Re: [Virtuoso-users] Question about LDP documentation

2023-12-01 Thread Hugh Williams via Virtuoso-users

Hi Mark,

That old wiki document is indeed out of date as  there is now a new “LDP 
enable/disable” checkbox option in the latest build for enabling LDP on WebDAV 
folders via the Conductor and not as an added WebDAV property as before, as 
detailed  in this new community forum post we have created:


https://community.openlinksw.com/t/using-virtuoso-as-ldp-client-and-server/4191

Note, there is also a fix for a missing “SPARQL_ADMIN” internal user account 
for DAV/LDP operations that has been made as detailed in following commit to 
the Virtuoso open source develop/7 branch:


https://sourceforge.net/p/virtuoso/virtuoso-opensource/ci/eddfba1a074416d4c6d8b99521c768d0b4f1189c/

And thus we would recommend updating your binary to this latest build to get 
this and other fixes ...

Re: [Virtuoso-users] Virtuoso support for ERA - Virtuoso backend

2023-11-30 Thread Hugh Williams via Virtuoso-users

Hi Ghislain,

Yes, I do remember from the publication office and Mondeca days, I am fine 
thanks and trust you are too …

The issues you report were logged as a support case#693 
<https://shop.openlinksw.com/support_system/customers/display_case.vsp?caseNumber=693>
 by Anestis from Deloitte (cc’ed in on this mail) who support the Virtuoso 
services hosted for EC Digit a few weeks ago. You can be given access to  by 
Anestis the case owner,  if you are registered on our support system, where 
such issues should always be logged so they can be managed and tracked 
centrally, rather than email threads. 

From the support case#693 
<https://shop.openlinksw.com/support_system/customers/display_case.vsp?caseNumber=693>
 the following updates were provided last week:

For Issue #1 - Wrong results for BIND depending on OPTIONAL/BIND order:

I created Virtuoso SPARQL to SQL 
<https://vos.openlinksw.com/owiki/wiki/VOS/VirtTipsAndTricksAnalyzingSPARQLQuery>
 plans for the two queries to see how they differ when translated to SQL for 
execution for analysis by development who report, it is very hard to say what 
exactly happens to SPARQL to SQL translation especially when nesting subqueries 
in coalsece/case so on. And would suggest to modifying the queries to the 
following which returns the correct results when the optionals are specified 
with the respective bind calls:

PREFIX eud: <http://data.europa.eu/949/>

SELECT DISTINCT ?AA ?BB ?CC ?DD
FROM <http://data.europa.eu/949/graph/rinf>
WHERE {
?AA a eud:OperationalPoint.
?AA eud:uopid ?EE.
FILTER(lcase(str(?EE)) = lcase("DEYBBMO"))

?AA eud:track ?BB.

OPTIONAL { ?BB eud:demonstrationINF ?CC_direct }
OPTIONAL { ?BB ?CC_tmp eud:demonstrationINF }
BIND(COALESCE(?CC_direct,?CC_tmp,eud:notData) AS ?CC )

OPTIONAL { ?BB eud:verificationINF ?DD_direct. }
OPTIONAL { ?BB ?DD_tmp eud:verificationINF }
BIND(COALESCE(?DD_direct,?DD_tmp,eud:notData) AS ?DD)
}

LIMIT 10

TEST server Live Link 
<https://test.virtuoso.ecdp.tech.ec.europa.eu/sparql?default-graph-uri==PREFIX+eud%3A+%3Chttp%3A%2F%2Fdata.europa.eu%2F949%2F%3E%0D%0A%0D%0ASELECT+DISTINCT+%3FAA+%3FBB+%3FCC+%3FDD+%0D%0AFROM+%3Chttp%3A%2F%2Fdata.europa.eu%2F949%2Fgraph%2Frinf%3E%0D%0AWHERE+%7B%0D%0A++%3FAA+a+eud%3AOperationalPoint.%0D%0A++%3FAA+eud%3Auopid+%3FEE.%0D%0A++FILTER%28lcase%28str%28%3FEE%29%29+%3D+lcase%28%22DEYBBMO%22%29%29%0D%0A%0D%0A++%3FAA+eud%3Atrack+%3FBB.%0D%0A%0D%0A++OPTIONAL+%7B+%3FBB+eud%3AdemonstrationINF+%3FCC_direct++%7D%0D%0A++OPTIONAL+%7B+%3FBB+%3FCC_tmp+eud%3AdemonstrationINF+%7D%0D%0A++BIND%28COALESCE%28%3FCC_direct%2C%3FCC_tmp%2Ceud%3AnotData%29+AS+%3FCC+%29%0D%0A%0D%0A++OPTIONAL+%7B+%3FBB+eud%3AverificationINF+%3FDD_direct.+%7D%0D%0A++OPTIONAL+%7B+%3FBB+%3FDD_tmp+eud%3AverificationINF+%7D%0D%0A++BIND%28COALESCE%28%3FDD_direct%2C%3FDD_tmp%2Ceud%3AnotData%29+AS+%3FDD%29%0D%0A%7D%0D%0A%0D%0ALIMIT+10+==text%2Fhtml=3>
where we assume ?BB ?CC_tmp eud:demonstrationINF and ?BB ?DD_tmp 
eud:verificationINF could be either notApplicable/notYetAvailable or not exists 
, the BIND can be moved around and would works.

Note the 'OPTIONAL { ?BB ?DD/CC_tmp eud:verificationINF }' simplification of 
'COALESCE(IF EXISTS...))' in the revised query.

Let us know if this works as expected ...

Development are going to look into this issue with the optionals with both 
original queries should return the same results, and so we will be dumping some 
of the <http://data.europa.eu/949/graph/rinf> graph data to recreate locally.

For issue #2 - Error in COALESCE division by zero:

I checked with development and they indicate the Virtuoso COALESCE "Divide by 
Zero" issue is a known problem from sometime ago and cannot readily be fixed in 
the Virtuoso SQL engine where the function is implemented. Generally the 
trapping and supressing of errors in such SQL functions cannot readily be 
passed back to the SPARQL layer without significantly affecting performance.

Re: [Virtuoso-users] Regarding Virtuoso's RDF Store

2022-11-16 Thread Hugh Williams via Virtuoso-users

Hi Jishnu,

What is the SQL database being used as RDF Store currently ?

With the Virtuoso commercially licensed edition its virtual database engine can 
be used to generate transient or persisted RDF views of data stored in ODBC or 
JDBC accessible relational databases as detailed at:

https://medium.com/virtuoso-blog/rdf-views-generate-b0538101a724
https://vos.openlinksw.com/owiki/wiki/VOS/VirtRdb2RDFViewsGeneration

Also, if the current RDF Store as the ability to dump its RDF data to datasets 
in one of the standard data representations ie  turtle, N-triple, NQuad, 
RDF/XML, as most do then those dataset can be bulk load directly into the 
Virtuoso commercial or open source product offerings as detailed at:

https://vos.openlinksw.com/owiki/wiki/VOS/VirtBulkRDFLoader

Note, the first method of creating RDF Views of the relational data cannot be 
done with the open source product as the virtual database engine required is a 
commercial only feature ...

Re: [Virtuoso-users] Unexpected results with geof:sfIntersects

2022-05-11 Thread Hugh Williams via Virtuoso-users

Hi Luís,

I would suggest reporting this issue on the Virtuoso open source git issue 
tracker at:

https://github.com/openlink/virtuoso-opensource/issues

which is where most now report issues or ask questions since we move to using 
git ...

Also, do you have a minimal test case for recreating the issue, as if so that 
should be provided as well ...

The Virtuoso built-in inferencing available in the open source product does not 
support owl:unionOf, and owl:intersectionOf. 

In the Virtuoso 8+ commercial edition support for the creation of custom 
inference rules of any type is support new custom inferencing engine available 
in this release as detailed at:

Re: [Virtuoso-users] problem restoring from Online Backup.

2020-10-21 Thread Hugh Williams via Virtuoso-users

Hi Skaros,

You need to specify the Virtuoso configuration ( ie INI) file with the -c or 
+configfile option when restoring the backup such that the database file(s) 
(without or with striping etc) the backup should be restore to ie

$ virtuoso-t +restore-backup bck +configfile virtuoso.ini

Wed Oct 21 2020

Re: [Virtuoso-users] database corruption after DB.DBA.DAV_QUEUE_RUN exit handler

2020-08-12 Thread Hugh Williams via Virtuoso-users

Hi Jorge,

I would suggest using the official OpenLink provided Virtuoso Docker images at:

 
https://community.openlinksw.com/t/virtuoso-enterprise-edition-docker-quick-start-guide/285

rather then the “tenforce/virtuoso” docker images which use older code base, 
and see if the same error occurs ...

Re: [Virtuoso-users] How to install isql?

2020-04-30 Thread Hugh Williams via Virtuoso-users

Hi Luis,

The Virtuoso client connectivity kit components are not licensed and can be 
freely redistributed, as in the commercial product it is the Virtuoso server 
where licensing is enforce for use.

Or why do you not use the open source “isql-vt” program Ubuntu provides as 
suggested previously ie 
http://manpages.ubuntu.com/manpages/cosmic/man1/ISQL-VT.1.html , which you can 
simply run the command "apt install virtuoso-opensource-6.1-bin" on ubuntu to 
install ie

root@ubuntu:/tmp/mozilla_hwilliams0# isql-vt

Command 'isql-vt' not found, but can be installed with:

apt install virtuoso-opensource-6.1-bin

 isql -?
Connection options:

  -?  - This help message
  -U username - Specifies the login user ID
  -P password - Specifies the login password
  -H server_addr  - Specifies the Server address (IP)
  -S server port  - Specifies the TCP port to connect to
  -E  - Specifies that encryption will be used
  -C  - Specifies that password will be sent in cleartext
  -X pkcs12_file  - Specifies that encryption & X509 certificates will
be used
  -T server_cert  - Specifies that CA certificate file to be used
  -b size - Specifies that large command buffer to be used
(in KBytes)
  -K  - Shuts down the virtuoso on connecting to it

Parameter passing options:

  -u name1=val1... - Everything after -u is stored to associative array U,
until -i is encountered. If no equal sign then value
is NULL
  -i  - Ignore everything after the -i option, after which 
comes arbitrary input parameter(s) for isql procedure,
which can be referenced with $ARGV[$I] by the
ISQL-commands.
  =   - Sets the ISQL options

  Note that if none of the above matches then the non-options go as

Re: [Virtuoso-users] How to install isql?

2020-04-28 Thread Hugh Williams via Virtuoso-users

Hi Luis,

What Virtuoso installation do you have as it you compile from source 
(http://vos.openlinksw.com/owiki/wiki/VOS/VOSUbuntuNotes 
<http://vos.openlinksw.com/owiki/wiki/VOS/VOSUbuntuNotes>), build and install 
the “isql” program is placed in the “bin” directory along with the Virtuoso 
binary.  Or a probably older version of Virtuoso is available on Ubuntu systems 
,see https://www.howtoinstall.me/ubuntu/18-04/virtuoso-opensource-6.1/ 
<https://www.howtoinstall.me/ubuntu/18-04/virtuoso-opensource-6.1/>  and that 
would include the “isql” program although I think they call it “isql-vt” and 
there is already an “isql” program in the system bin directory used for 
something else.

Re: [Virtuoso-users] reset DBA password

2020-04-17 Thread Hugh Williams via Virtuoso-users

Hi Alfredo,

If you are restoring a backup of the current database or is password was not 
changed since the last backup then it must restore with the same password. That 
is unless the restore actually failed and when you restarted Virtuoso actually 
an empty database with the default dba/dba  uid/pwd is created, thus I would 
suggest trying “dba” as a password first and if this is successful you need to 
determine why the restore was not successful.

No we do not provide prebuilt open source binaries for Solaris, thus you would

Re: [Virtuoso-users] What is preventing external connections to TCP port 1111 to connect to Virtuoso running within a Docker container?

2019-10-03 Thread Hugh Williams

Hi Allan,

If you can access the HTTP port 8890 from external machine then there is no 
reason why you would not be able to access the SQL TCP port  (given you can 
access it from the host machine ie localhost:1112) other then there is a 
problem with the network firewall on the host machine (or wherever this is 
enforced) that is prevent access to TCP port 1112 from external machines. Thus 
you should check your fire walling ...

BTW, I presume this is you own docker image that was create, rather then using 
the OpenLink Virtuoso 7 open source docker image at:

https://hub.docker.com/r/openlink/virtuoso-opensource-7/ 
<https://hub.docker.com/r/openlink/virtuoso-opensource-7/>

Re: [Virtuoso-users] Is there a way to send SPARQL queries via curl (over HTTP) to Openlink Virtuoso and obtain the results in JSON format.

2019-07-02 Thread Hugh Williams

Hi Allan,

The are various ways to send curl commands to Virtuoso to perform SPARQL / 
SPARUL queries like:

curl --request POST 'http://localhost:8890/sparql/?' --data-urlencode 
'query=select * from  <http://example.org> where {?s ?p ?o} limit 5’

cat query.rq 
select * from  <http://example.org> where {?s ?p ?o} limit 5

curl --request POST http://localhost:8890/sparql --data-urlencode 
"format=csv" --data-urlencode qu...@query.rq

curl --request POST 'http://localhost:8890/sparql-auth/?' --digest 
--user dba:dba --data-urlencode 'query=INSERT INTO GRAPH <http://example.org> { 
<1> <2> <3> }'

Hi Peter,

The triple value do indeed appear to be valid, but the problem could be 
somewhere else in the dataset file and not necessarily on the reported line or 
line before it.

Is it a public dataset you are loading and if so can you provide a copy for 
local testing ?

Re: [Virtuoso-users] GeoSPARQL

2018-11-15 Thread Hugh Williams

Hi Pasquale,

The new GeoSPARQL feature is in the git develop/7 branch for which prebuilt 
binaries are not available and would thus have to be compiled from:

https://github.com/openlink/virtuoso-opensource/tree/develop/7 
<https://github.com/openlink/virtuoso-opensource/tree/develop/7>

Re: [Virtuoso-users] Unable to load procedure code.

2018-09-30 Thread Hugh Williams

Hi Fernando,

You should be able to use the isql “set blobs on;” command to view the LONG 
VARCHAR column values:

SQL> help set;
SET TIMEOUT sec   to set transaction timeout to sec seconds
AUTOCOMMIT ON/OFF/MANUAL to set whether to autocommit or not.
  Default is OFF
READMODE SNAPSHOT or NORMAL to switch between non-locking and normal read
ACCESSMODE RO or RW to switch between read-only and read-write connection
MAXROWS num   to set the max. limit of rows printed with select.
  Use the value zero to print always all rows.
DEADLOCK_RETRIES num  to set the max. limit of deadlock retries.
BLOBS ON or OFF   to control whether LONG VARCHAR columns are printed
TIMES2STRINGS ON or OFF to control how timestamps are printed
BANNER ON or OFF  to control whether the banner is shown with select
TYPES ON or OFF   to control whether column types are shown in banner
VERBOSE ON or OFF to control whether information about execution times,
  etc, are printed.
PROMPT New Prompt> or OFF to set the new prompt or turn off prompting
HIDDEN_CRS CLEARED or PRESERVED to control whether trailing CRs of MS-DOS
   files are cleared from foreach blobs. Note that all explicit
   \15 escape-sequences are always kept in the content.
ERRORS STDOUT or STDERR to control where error messages are directed.
ECHO ON or OFFto control whether statements are echoed.
Use SHOW to show the current values of these parameters.
Help more?>
You can specify these options on the command line also, for example
/opt/virt-geosparql/isql VERBOSE=OFF BANNER=OFF PROMPT=OFF BLOBS=ON 
ERRORS=STDOUT
You can also run one or more ISQL-commands directly from the command line with
EXEC=statement option. E.g. "EXEC=select * from fyyl" The statement(s)
are executed and no further input is asked, unless foreach statement is used.

Your URLs are not accessible external and just hang trying to load, thus is

Re: [Virtuoso-users] Error SR078: The result set is too long, must limit result for at most 2097151 rows

2018-09-06 Thread Hugh Williams

Hi Peter,

You can get around this by using LIMIT / OFFSET in the query or by using one of 
the SQL interfaces ie ODBC / JDBC / ADO.Net etc as was indicated in the git 
issue (https://github.com/openlink/virtuoso-opensource/issues/700) and even 
using our Jena/Sesame Provider which use JDBC under the covers for connecting 
to Virtuoso ...

Re: [Virtuoso-users] SPIN rules chaining in Virtuoso 8

2018-09-02 Thread Hugh Williams

Hi Adam,

As indicated previously SPIN / Custom Inferencing functionality is a Virtuoso 8 
commercially license product feature and not available in the Virtuoso open 
source product this mailing list is targeted at. Thus using the commercial 
product you should log an online support case with us, where the issue can be 
picked up by one of our consultants at:

http://support.openlinksw.com/support/online-support.vsp

Also, I don’t understand the rule you are seeking to create as a rectangle 
cannot have a volume, so you are  calculating the area as width * height  , and 
then multiplying area * height to get volume, which is incorrect, as you would 
need to depth (or length) to calculate the volume of a cube ie box effectively 
? Or are you just using this to demonstrate the chaining of rule results being 
sought ?

BTW, running your scripts I don’t get the error you report, as both the first 
one wich runs completion without error, although volume is not returned, thus 
what is the version of Virtuoso 8 being used, which can be obtained by running 
the command the the “bin” directory of your installation:

./virtuoso-iodbc-t -?

The second script gives error:

 Error SPINX: VD [Virtuoso Server]SPIN graph top-level subject 
http://example.org/shapes#rs1 is of unsupported rdf:type 
http://www.w3.org/1999/02/22-rdf-syntax-ns#Property

To get your first script to run  changed the rule to:

SPARQL 
PREFIX shapes: <http://example.org/shapes#> 
PREFIX spin:<http://spinrdf.org/spin#>
PREFIX sp: <http://spinrdf.org/sp#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX owl: <http://www.w3.org/2002/07/owl#>

WITH  
INSERT {

spin:rule [
   a sp:Construct;

   WHERE {
   {
   SELECT ?this (xsd:float(?height) * 
xsd:float(?width)) AS ?area
   WHERE { 
   ?this 
<http://example.org/shapes#width> ?width ; 
 
<http://example.org/shapes#height> ?height . 
 } 
   }
   }
  """
  ] ;
spin:rule [
   a sp:Construct;
   sp:text """ 
   CONSTRUCT { ?this 
<http://example.org/shapes#volume> ?volume }
   WHERE {
   {
   SELECT ?this (xsd:float(?height) * 
xsd:float(?height) *  xsd:float(?width)) AS ?volume
   WHERE { 
   ?this 
<http://example.org/shapes#width> ?width ; 
 
<http://example.org/shapes#height> ?height . 
 } 
   }
   }
  """
  ] .
} 

Done. -- 5 msec.

-- Line 109: EXEC ('SPARQL ' || 
SPARQL_SPIN_GRAPH_TO_DEFSPIN('urn:spin:rule:geometry:lib'))

Done. -- 200 msec.

Which is essentially what your first script is seeking to do, but  ?area from 
the first rule does not seem to be available to the second rule as it has not 
been evaluated it seems, which is what you seem to be hoping it will as part of 
a chain ?

Although as said you should log an online support case for this issue

Re: [Virtuoso-users] virtuoso-opensource install providing dba and dav passwords as command line parameters

2018-08-31 Thread Hugh Williams

Hi Matteo,

The +pwdold +pwddba +pwddav options can be passed to the Virtuoso server binary 
to change the “dba” and “dav” user password, see:

$ ./virtuoso-t -?
Virtuoso Open Source Edition (Column Store) (multi threaded)
Version 7.2.6-dev.3229-pthreads as of Aug 15 2018 (7f57cb6fe)
Compiled for Darwin (x86_64-apple-darwin17.6.0)
Copyright (C) 1998-2018 OpenLink Software

Usage:
  virtuoso-t [-fcnCbDARwMKrBd] [+foreground] [+configfile arg] [+no-checkpoint]
 [+checkpoint-only] [+backup-dump] [+crash-dump]
 [+crash-dump-data-ini arg] [+restore-crash-dump] [+wait]
 [+mode arg] [+dumpkeys arg] [+restore-backup arg]
 [+backup-dirs arg] [+debug] [+pwdold arg] [+pwddba arg]
 [+pwddav arg]
  +foregroundrun in the foreground
  +configfileuse alternate configuration file
  +no-checkpoint do not checkpoint on startup
  +checkpoint-only   exit as soon as checkpoint on startup is complete
  +backup-dump   dump database into the transaction log, then exit
  +crash-dumpdump inconsistent database into the transaction log, 
then exit
  +crash-dump-data-ini   specify the DB ini to use for reading the data to dump
  +restore-crash-dumprestore from a crash-dump
  +wait  wait for background initialization to complete
  +mode  specify mode options for server startup (onbalr)
  +dumpkeys  specify key id(s) to dump on crash dump (default : all)
  +restore-backuprestore from online backup
  +backup-dirs   default backup directories
  +debug Show additional debugging info
  +pwdoldOld DBA password
  +pwddbaNew DBA password
  +pwddavNew DAV password

You could also use an “autoexe.isql” file to change the pwd  as follows :

1. Go the the Virtuoso database directory where the configuration files for the 
database instance reside ie virtuoso.ini, virtuoso.log etc ; and create  a file 
called "autoexec.isql" with the following contents:

user_set_password ('dba', ‘your-pwd’)
user_set_password ('dav', ‘your-pwd')
;

2. Then start the database as normal and the pwd will be changed.

3.  Finally remember to remove the auotexec.isql script to prevent it being 
reset again when next started …

Note the “i” in the name of the “autoexec.isql” file, which many miss ...

Re: [Virtuoso-users] Virtuoso 8 - total number of output rows is always 25 or less

2018-08-30 Thread Hugh Williams

Hi Adam,

If you are using Virtuoso 8 then this must be the commercially license version 
which has a built-in demo license that does restrict the number of rows to 25 
in a result set as detailed at:

https://medium.com/virtuoso-blog/built-in-virtuoso-demo-license-f29a1bf0ccf3 

Implying that either a valid commercial license is not in place or if you have 
an evaluation license it has expired resulting the the built-in license being 
invoked on startup.

Check your “virtuoso.log” file in the database directory which will detail the 
license pickup on startup ...

Re: [Virtuoso-users] LDAP authentication or import.

2018-08-08 Thread Hugh Williams

Hi Fernando,

In the Virtuoso Conductor LDAP UIs the version defaults to version 2, but they 
have a drop down list box to enable this to be changed to 3

What interface is being used when the authentication fails and what is the 
actual error being reported when attempting to authenticate and what are the 
actual parameters being set LDAP server configured in the Virtuoso Conductor ?

Hi Nauman,

This is the list of default users created Virtuoso:

U_NAME
VARCHAR NOT NULL
___

PKI
PROXY

The “dba” , “dav” users should not be removed as these are Admin user accounts  
... the “SPARQL” , “SPARQL_ADMIN” accounts are special accounts required for 
SPARQL/RDF  access  ... the other users accounts I doubt are required ... still 
not sure why you want to delete all users from a default installation ?

Hi Nauman,

Virtuoso has a user_drop() function as detailed at:

http://docs.openlinksw.com/virtuoso/fn_user_drop/

Or you can delete them via the Conductor  “System Admin” -> “User Accounts” tab

Note the special “dba” Administrative user account cannot be deleted ...

Re: [Virtuoso-users] locking down sparql endpoint

2018-04-20 Thread Hugh Williams

Hi Erich,

You could disable the /sparql endpoint from the Conductor “Web Application 
Server -> Virtual Domains & Directories” tab and either:

1. Delete the /sparql virtual directory

2. Edit the /sparql virtual directory and set the “VSP User”  from “dba” to 
“nobody” , that way you can always set it back to “dba” should you want to 
reenable it 

and there are probably other methods ...

Re: [Virtuoso-users] Unicode in Virtuoso

2018-03-27 Thread Hugh Williams

Hi Erich,

When you say bulk update method I presume you mean with the Virtuoso RDF Bulk 
Loader ie 
https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtBulkRDFLoader  ?

If so are you able to provide a sample NT file for upload to recreate locally , 
as we have not had such complaints and Virtuoso is used for hosting datasets in 
many languages with unicode chars which are uploaded using the bulk loader ?

Hugh Williams

Re: [Virtuoso-users] No bif:match other than bif:contains?

2018-02-13 Thread Hugh Williams

Hi Jason,

No such bif:match function exists in Virtuoso ...

You should be able to use a filter clause in conjunction with bif:contains to 
get a performant exact match with something like:

select * where {?s ?p ?o . ?o bif:contains '"Nevis"' FILTER 
(?o="Nevis"@en)}

See the following live example against DBpedia:

http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org=select+*+where+%7B%3Fs+%3Fp+%3Fo+.+%3Fo+bif%3Acontains++%27%22Nevis%22%27+FILTER+%28%3Fo%3D%22Nevis%22%40en%29%7D=text%2Fhtml_redir_for_subjs=121_redir_for_hrefs==3=on=+Run+Query+
 
<http://dbpedia.org/sparql?default-graph-uri=http://dbpedia.org=select+*+where+{?s+?p+?o+.+?o+bif:contains++%27%22Nevis%22%27+FILTER+(?o=%22Nevis%22@en)}=text/html_redir_for_subjs=121_redir_for_hrefs==3=on=+Run+Query+>

Re: [Virtuoso-users] indexTreeMap set twice

2018-02-08 Thread Hugh Williams

Hi Henrik,

I see what you there are 2 entries for IndexTreeMaps in the default open source 
INI file . The default value for IndexTreeMaps is 256 as indicated in the docs 
at:

http://docs.openlinksw.com/virtuoso/dbadm/ 
<http://docs.openlinksw.com/virtuoso/dbadm/>

and in a commercial Virtuoso INI file the value is 64, which is probably where 
the confusion has come from, so will have development remove the 256 value as I 
suspect the 64 value used in commercial is what open source should use for a 
base installation ...

Re: [Virtuoso-users] Virtuoso Open Source Edition 7.2.5-dev compile failure: no member named 'mp_alloc_file' in 'struct mem_pool_s'

2018-02-06 Thread Hugh Williams

Hi Cameron,

In your config.nice file do you add the “--with-debug” configure option, as we 
find the error you report occurs when it is enabled, which development need to 
look into. In the meantime please remove the --with-debug option, which is not 
require for a default build, and rerun config.nice and then run "make clean" 
followed by “make" to recompile without the option enabled.

Re: [Virtuoso-users] Query optimization, possible indexing?

2018-01-25 Thread Hugh Williams

Hi Quentin,

Thanks for the input, I see what you mean as the jena program is executing the 
query:

String qStr = "PREFIX base: <http://base.org#> PREFIX xsd: 
<http://www.w3.org/2001/XMLSchema#>  SELECT ?s {?s base:name 
\"test_sensor\"^^xsd:string}";

and does actually return results when run against isql:

SQL> SPARQL define input:default-graph-uri   PREFIX  xsd:  
<http://www.w3.org/2001/XMLSchema#> PREFIX  base: <http://base.org#>  SELECT  
?s WHERE   { ?s  base:name  "test_sensor"^^xsd:string };
s
LONG VARCHAR
___

http://base.org#x1
http://base.org#x2

2 Rows. -- 101 msec.
SQL>

But when I set Virtuoso trace_on() ^^xsd:string  element is being stripped off 
by time it gets to Virtuoso ie

define input:default-graph-uri  
PREFIX  xsd:  <http://www.w3.org/2001/XMLSchema#>
PREFIX  base: <http://base.org#>

SELECT  ?s
WHERE
  { ?s  base:name  "test_sensor" }

which I assume must be done by the Jena Provider, thus we need to check this ...

Hi Jason,

I would suggest compiling from source to get the FCT vad for the Virtuoso 
binary you are also compiling, although generally VADs built from other 
archives should work ...

Re: [Virtuoso-users] Install VOS behind a proxy with path.

2017-09-22 Thread Hugh Williams

Hi Fernando,

Have you tried using the mod_proxy_html module as detailed in the last post at:


https://serverfault.com/questions/561892/how-to-handle-relative-urls-correctly-with-a-reverse-proxy

To make a reverse proxy:

1. Install mod_proxy_html 

yum install mod_proxy_html

• Load mod_proxy_html module 

LoadModule proxy_html_module modules/mod_proxy_html.so

• And use following setting

ProxyRequests off  
ProxyPass /folder/  http://test.madeupurl.com  
ProxyHTMLURLMap http://test.madeupurl.com  /folder  

  
ProxyPassReverse /  
ProxyHTMLEnable On  
ProxyHTMLURLMap  /  /folder/  
RequestHeaderunset  Accept-Encoding

[Hugh] This is not possible as there are internal process within Virtuoso 
itself that need write access to the database.

Hi André,

Not that we are aware of. does not know if such exists. However you can run the 
Virtuoso isql command line tool [1] in a shell buffer and interact that way 
possibly ...

Hi Paquale,

The HTTP logs cannot be directed to STDOUT, and not sure why this would be 
needed for a docker image, as the logs should still be accessible via file 
system from where you should be able to process them ...

The steps to recreate this issue via SQLWorkBench and the JDBC driver is what

Re: [Virtuoso-users] graph group access

2017-06-26 Thread Hugh Williams

Hi Roland,

By sparql interface, I assume you mean the Virtuoso default /sparql endpoint ? 
I tried this myself on my test instance and can query the same data from my 
/sparql endpoint as I can from isql.

What happens if you query via the /sparql-auth  protected default endpoint and 
authenticate as the “dba” user can you then query the graphgroup and get 
results ?

What is the complete sequence of command that have been run against you 
Virtuoso instance to setup the graph group test  ?

Re: [Virtuoso-users] graph group access

2017-06-22 Thread Hugh Williams

Hi Roland,

This works for me:

SQL> SPARQL INSERT INTO GRAPH <http://example.org> { <1> <2> <3> };

Done. -- 4 msec.
SQL> DB.DBA.RDF_GRAPH_GROUP_CREATE ('graphgroup', 0);

Done. -- 1 msec.
SQL> DB.DBA.RDF_GRAPH_GROUP_INS ('graphgroup','http://example.org');

Done. -- 2 msec.
SQL> SPARQL SELECT * FROM  where {?s ?p ?o};
s   
  p 
o
LONG VARCHAR
  LONG VARCHAR  
LONG VARCHAR
___

1   
  2 
3

1 Rows. -- 253 msec.
SQL>

Please provide steps to reproduce your issue preferably via isql so all steps 
and results can clearly be seen ...

What user are you connecting with, as typically graph groups are used to 
control access to specific user or groups of users as in the example at:

http://vos.openlinksw.com/owiki/wiki/VOS/VirtRDFGraphsSecurity

and permissions need to be accessed to the specific user for accessing the 
graph group which is not indicate in your mail to have been done, thus I assume 
you are connecting as the default “dba” or sparql user ?

2017-06-22 Thread Hugh Williams

Hi Beppe,

I am confused now as the original test case provided for recreating did not use 
SQLWorkbench or JDBC, so how can the issue then be recreated ?

Re: [Virtuoso-users] Adding virtuoso to rdf4j failed

Hi Adam,

What is the version of the Virtuoso RDF4J Provider and JDBC driver being used:

java -jar virt_rdf4j.jar
java -jar virt_jdbc4_2.jar

as the components where updated last week and work for Henrik, thus want to 
check you are using these ?

Hi Henrik,

That is true, the sources are included as well such that gradle can recompile 
if need be, but a compiled jar is provided also, so this is not necessary 
unless the sources are changed. Anyway the source files have also been updated 
and the zip file replaced ...

Re: [Virtuoso-users] Adding virtuoso to rdf4j failed

2017-06-13 Thread Hugh Williams

Hi Henrik,

The “rdf4j_virtuoso.zip” does not compile the virt_rdf4j.jar provider which is 
included as a prebuilt jar ...

It appears the the Version 2.1.4 [Build 1.2] jar is problematic as when I used 
that one I got the error you report. There is a later build:

De-iMac:rdf4j hwilliams$ java -jar ./virt_rdf4j.jar 
OpenLink Virtuoso(TM) Provider for RDF4J(TM) Version 2.1.4 [Build 1.3]
De-iMac:rdf4j hwilliams$

which is in the git develop/7 branch, and testing with that build I can then 
create a New Repo and insert & query data ...

Thus I have updated the “rdf4j_virtuoso.zip” and the virt_rdf4j.jar provider 
available for online download and referenced in the documentation, which should 
now work whether the jar or zip is downloaded for use ...

Hugh Williams

Re: [Virtuoso-users] Adding virtuoso to rdf4j failed

2017-06-05 Thread Hugh Williams

Hi Henrik,

I presume you are following the instructions at:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository
 
<https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtSesame2HttpRepository>

When during the addtion of the repo is the error occurring ? I assume Virtuoso 
is at least listed as an available repository and you have provide connection 
details and if so please provide the details of the connection params passed ? 
And it is at the point of added the Virtuoso repo that the error is occurring ?

If the RDF4J HTTP server is attempting to connect to Virtuoso then you can 
enable tracing to the “virtuos.log” file using the trace_on() function as 
detailed at:

http://docs.openlinksw.com/virtuoso/fn_trace_on/ 
<http://docs.openlinksw.com/virtuoso/fn_trace_on/>

Which should provide details of what is occurring in Virtuoso and hence 
possible cause of the problem ...

Hugh Williams

Re: [Virtuoso-users] Conductor behind ssl?

2017-05-04 Thread Hugh Williams

Hi Roland,

What is the URL actually giving the "The requested active content cannot be 
displayed due to execution restriction” error ? I presume https://hostname:4433 
 rather then https://hostname:4433/conductor which I would expect to give a 404 
error as there would be no /conductor  virtual directory for it to map to ?

To get rid of the  "The requested active content cannot be displayed due to 
execution restriction” error on https://hostname:4433 you would need to:

1. From the Conductor UI on the http default (8890) port go to the “Web 
Application Server -> Virtual Domain & Directories” tab and click on the folder 
icon of the HTTPS listener  virtual domain/host you created to view its list of 
virtual directories

2. Edit the “/“ ie root virtual directory which would be reading from 
the “ServerRoot” param setting in the INI file and set the “Default Page” to be 
“index.html” such that it load the index.html in that location. Then set the 
“VSP user” of the same vdir to be “dba”  (rather then “none").

Then the Virtuoso home page should load on the https listener port

To access the Conductor on the HTTPS listener port you would then need to 
duplicate the Virtual Directory [1] entry of the /conductor virtual directory 
for the Default HTTP listener ie 8890 which you can see its setting by editing 
the /conductor vdir for that existing http listener and use the entries to make 
the duplicate required for the HTTPS listener, at which point the conductor can 
then be access by it.

Once you have verified you can access the Conductor via the HTTPS listener, you 
can then delete the /conductor virtual directory on the default HTTP listener 
if you don’t want user to access it via the HTTP listener anymore or even 
create a rewrite rule [2] for it to  redirect it to the HTTPS listener.

Hi Mark,

Did you try a build from the Virtuoso git develop/7 branch 
(https://github.com/openlink/virtuoso-opensource) ie Version 7.2.5-dev.3217 as 
you indicated you would  when you asked this question in March, as this problem 
did not occur when I built from this branch ?

When exactly is the error occurring ?

I built against the latest develop/7 git tree and the FCT browser works for me:

Done. -- 5 msec.
SQL> VT_INC_INDEX_DB_DBA_RDF_OBJ ();

Virtuoso Open Source Edition (Column Store) (multi threaded)

Thus would suggest building against that branch to see if the error occurs ...

Re: [Virtuoso-users] Write load high relative to disk write throughput / intensive JDBC sparql INSERT DATA INTO GRAPH

2017-03-22 Thread Hugh Williams

Hi Thomas,

Looking at your INI file I note in the “[Parameters]” section you have  
"MaxClientConnections = 10” set , which should be set to something like 100 
I would recommend as this param sets the number of ServerThreads available to 
the SQL database for processing requests, which includes SQL connection and 
threads used by the server for internal processes/tasks, which are allocated on 
demand. The "MaxClientConnections = 10” setting in the “[HTTP Server]” 
section can be left as is as this is used for the  HTTP Web Server thread pool 
and are pre-allocated on server startup for use in the thread pool.

2017-03-19 Thread Hugh Williams

Hi Thomas,

Is the loading of the dataset now complete or it is still in progress as you 
opening statement is not clear ?

You should not need 40GB RAM for inserting and hosting 240 million triples, 
which should require less then 10GB depending on how well they can be 
compressed for storage in the database.

I assume you have set the swappiness as suggested previously ?

When you recompiled your Virtuoso was this done from the git stable/7 or 
develop/7 branch , as I latter has a number of memory consumption fixes that 
would not be in stable/7, thus I would suggest building from develop/7.

Have you provided a copy of your INI file previously,  if not can you provide a 
copy ?

Do ensure the following params are set to 1 in order to clean up unused 
threads/resources and reduce memory consumption of the Virtuoso server, which 
can otherwise be construed as memory leaks.:

ThreadCleanupInterval= 1
ResourcesCleanupInterval = 1

Re: [Virtuoso-users] Running to VOS with one virtuoso.db

2017-03-16 Thread Hugh Williams

Hi Ghislain,

The HTTP ports ( and SQL ports) cannot be the same for the two instances 
running on the same machine, they would have to be unique as I indicated 
previously, As if the ports are the same then the first to start will run and 
the other would fail to state with an “address already in use” type error in 
the Virtuoso file ...

Re: [Virtuoso-users] Write load high relative to disk write throughput / intensive JDBC sparql INSERT DATA INTO GRAPH

2017-03-10 Thread Hugh Williams

Hi Thomas,

Is the ORCID dataset the only RDF datasets in the Virtuoso RDF Quad Store 
currently, or are there others ?

What is the size of the ORCID dataset ie triple count ?

I would definitely suggest setting swappiness to 10 to reduce swapping to disk 
which should speed inserts rates.

Looking at you status() command output I see "Clients: 4177045 connects, max 3 
concurrent”  indicating more than 4 million SQL connections have been made to 
Virtuoso since it was started on 9th Mar . What is making that many 
connections, it is this insertion process or are there other clients reading 
from the instance also ? Apart from that the status() output looks fine with 
please of unused Buffers for database working set size to be increased and 
still fit in memory , no deadlock and only one pending transaction which is one 
of your inserts.

You talk about the Oracle JDBC Driver but I still don’t see its relevance as 
ultimately your insertions to Virtuoso must be done one of its client 
interfaces / services ie either the /sparql endpoint or the Virtuoso JDBC 
driver I would presume, thus which is it ?

The "DEFINE sql:log-enable 2” pragma being passed in the SPARQL insert queries 
does set row by row auto-commit and turn off transaction logging, which is the 
fastest transaction mode for write operations, see:

http://docs.openlinksw.com/virtuoso/fn_log_enable/

Re: [Virtuoso-users] Write load high relative to disk write throughput / intensive JDBC sparql INSERT DATA INTO GRAPH

2017-03-09 Thread Hugh Williams

Hi Thomas,

What is this JDBC Connector from Oracle that is being used for the inserts in 
RDF/XML form ?

What is the ORCID dataset being used as the only one I see is in N-Triple 
format from 2014 at:

https://datahub.io/dataset/orcid_2014_dataset 
<https://datahub.io/dataset/orcid_2014_dataset>

Performing inserts with transaction would consume more memory maintaining the 
transaction than with log_enable(2) which auto commits without transaction 
logging in memory.

The  O_DIRECT param set in your INI file is an old param for which no real 
benefit has been seen on current OS’es and on a Linux system setting swappiness 
as detailed at:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning#Linux-only%20--%20”swappiness;

Would give better results.

There is also no real need to set ColumnStore = 1 as for as the RDF_QUAD tables 
is column store by default in Virtuoso 7 , so that setting would only have 
effect on default SQL table creation

If you still have problems, can you provide a copy of your virtuoso.log file 
and the output of the “status();” command for review ...

Re: [Virtuoso-users] Unable to delete a graph content / Unable to iterate on graph triples - Same problem?!

2017-03-07 Thread Hugh Williams

Hi Beppe,

If these are RDF Linked Data View “Virtual” Graphs then these are stored in a 
different Quad Map storage location, see:


http://docs.openlinksw.com/virtuoso/rdfviewquadmapatternsvalueandiriclasses/

But you should be able to delete such graphs wit the “drop graph ” 
sparql query as indicated in the “Delete RDF Graphs” section of the following 
white paper on "Mapping Relational Data to RDF with Virtuoso's RDF Views” :


https://virtuoso.openlinksw.com/whitepapers/relational%20rdf%20views%20mapping.html

Or the indicated alternative SQL method of manually deleting Virtual graphs 
(from when drop graph was not supported) can be used ...

Hi Beppe,

That should be all that is required on the server for Unicode / UTF-8 support. 

Do you have a test case for recreating the problem being observed, which should

Re: [Virtuoso-users] Conversion to RDF issue.

2017-02-24 Thread Hugh Williams

Hi Imane,

Ah, you are on the open source mailing list also ... which answers my question 
in the other mail thread ... do you have a local Virtuoso instance and if so 
what version ( run “virtuoso-t -?”) ?

Querying the RDF data in the named graph for that generated page directly from 
the Virtuoso RDF Quad Store on our UriBurner service I do not see a problem 
with it:

http://linkeddata.uriburner.com/sparql?default-graph-uri=https%3A%2F%2Fwww.amazon.fr%2FOpen-Data-Now-Investing-Innovation%2Fdp%2F0071829776=select+*+where+%7B%3Fs+%3Fp+%3Fo%7D==text%2Fhtml_redir_for_subjs=121_redir_for_hrefs==3000
 
<http://linkeddata.uriburner.com/sparql?default-graph-uri=https%3A%2F%2Fwww.amazon.fr%2FOpen-Data-Now-Investing-Innovation%2Fdp%2F0071829776=select+*+where+%7B%3Fs+%3Fp+%3Fo%7D==text%2Fhtml_redir_for_subjs=121_redir_for_hrefs==3000>

Thus what is the problem in protégé , which is not a product I am familiar with 
?

Re: [Virtuoso-users] Scope of log_enable and effect on deletes

2017-02-21 Thread Hugh Williams

Hi Daniel,

What Virtuoso open source or commercial  release and build date or git tree are 
you using / building from ?

I don’t understand how your first query reports 4393 subjects and then in your 
last statement you say there should be 2 million ?

What is the total triple count of the <http://id.nlm.nih.gov/mesh/updates> 
graph ?

Do you have log_enable() set when running the delete query and if so what is it 
set to ?

Re: [Virtuoso-users] {Disarmed} Re: {Disarmed} Re: SQ156: Internal Optimized compiler error : sqlo table has no index in

2017-02-13 Thread Hugh Williams

Hi Jerven,

In Virtuoso 7+ the  RDF_QUAD table is created with COLUMN (column wise) indexes 
by default, whereas you seem to have been creating additional BITMAP (row wise) 
indexes , which is not recommended ie mixing column and row wise indexes as 
this can result in the unpredictable behaviour you are experiencing, see:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning#RDF
 Index Scheme 
<https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning#RDF%20Index%20Scheme>

Is there a reason why these additional indexes were being tried as the 5 
default (2 full & 3 partial) column wise indexes should suffice for most use 
cases, with only one exception found to date which is detailed in the Index 
Scheme Selection section of the Wiki doc:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning#Index

Re: [Virtuoso-users] SQ156: Internal Optimized compiler error : sqlo table has no index in

2017-02-06 Thread Hugh Williams

Hi Jerven,

Does the same error occur when the query is run against the /sparql endpoint or 
isql  ie not via the JDBC Driver ?

Also, are you able to get the  query “profile” or “sparql_to_sql_text” for the 
query as detailed at:

https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksAanalyzingSPARQLQuery

<https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksAanalyzingSPARQLQuery>

What version of Virtuoso is being used, is it a latest 07.20.3217 build ?

Re: [Virtuoso-users] Running to VOS with one virtuoso.db

2017-01-26 Thread Hugh Williams

Hi Pasquale,

What is the purpose of running two Virtuoso instances, is this for setup access 
for SPARQL or SQL storage ?

The easiest way to start multiple Virtuoso database instances on the same 
machine is to create two separate databases with a “virtuoso.ini” file on each 
set to use unique SQL & HTTP ports and then start each in the separate 
directories with a lock file for each …

Re: [Virtuoso-users] loaded data doesn't bind to graph specified

2017-01-26 Thread Hugh Williams

Hi Roland,

Is this not the same method you have loaded DBpedia NL datasets in the past ? 
In which case what is different with this new dataset load ?

What other graphs are in the Quad Store:

SPARQL SELECT ?g COUNT(*) { GRAPH ?g {?s ?p ?o.} } GROUP BY ?g ORDER BY 
DESC 2;

and can you query and of the other graphs with the name specified in the 
“Default Data Set Name” field (from)

Also, does the following return results when run from the isql command line 
tool:

sparql select * from <http://nl.dbpedia.org>  { ?s foaf:depiction ?pic 
} limit 100;

Re: [Virtuoso-users] Virtuoso upgrade in Ubuntu

2017-01-14 Thread Hugh Williams

Hi Iker,

I suspect your Virtuoso 6 installation is the default pre-built bundled with 
Ubuntu 14.04, which get installed in specific locations they specify, whereas 
you have compiled Virtuoso 7.2 from source which would install in its own 
default locations which I different to the Virtuoso 6 locations specified by 
Ubuntu. See the following documentation on how to compile using the Ubuntu 
specific locations:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSUbuntuNotes 
<https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSUbuntuNotes>

Note you would probably have to update your Ubuntu installation to the latest 
to get a pre-built bundled Virtuoso 7 installation by them …

Re: [Virtuoso-users] Parallel backup_online invocation

Hi Jerven,

Happy New Year !!!

The online backup is a sequential process and thus runs on a single thread and 
hence core and cannot be run across multiple threads ie in parallel as 
suggested …

Re: [Virtuoso-users] Memory allocation

2016-12-10 Thread Hugh Williams

Hi Roland,

I assume you are referring to the setting of the “NumberOfBuffers” INI file 
param, which it is recommended be set to 2/3 to 3/5 of available memory as 
detailed in the Virtuoso performance tuning guide at:

https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning

which is the maximum memory Virtuoso would allocate for hosting the database 
working set in memory, before it starts swapping to and from disk, which would 
significantly degrade performance.  

Virtuoso would need to allocate additional memory for query execution dependant 
on the type of query being executed ie to compile, execute result set, which is 
why the recommendation is to allocate 2/3 to 3/5 of available memory such that 
memory is available for servicing requests.

Re: [Virtuoso-users] Space allocation for master database

2016-11-26 Thread Hugh Williams

Hi Pasquale,

Note sure what you are seeking the Master database space allocation is the size 
of the virtuoso.db file on disk ie 138MB and it will grow dynamically as 
required, thus provided you have more free disk space on the file system as the 
database grows you should be fine.

More important is the Memory allocation to Virtuoso for hosting the database 
working set with the “NumberOfBuffers” INI file param, see the RDF Performance 
tuning guide at:

https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtRDFPerformanceTuning

and monitor the allocated and used buffers with the “status()” command run from 
isql

20 buffers, 183153 used

which is the key to performance ie being able to host the database working in 
memory, rather than having to read from disk which kills performance …

Re: [Virtuoso-users] Transaction in Virtuoso over HTTP

2016-11-26 Thread Hugh Williams

Hi Nauman,

Why are you asking this question again, having already asked this on stack 
overflow and  the git issue tracker, were the response was:

This is an issue of Transaction Semantics Fidelity i.e., how much control do 
you have over transactions. By default, all SPARUL statements a committed 
following execution, or rolled back. A Virtuoso SPARQL Endpoint provides basic 
auto commit transaction functionality.

You need a semantically rich transaction layer (as per what you referenced) 
when you want more specific conditional behavior provided by isolation levels, 
transaction blocks, and rollbacks or commits. Which as indicated in your email 
to support is available via one of the SQL Data Access interfaces ie 
ODBC/JDBC/ADO.Net/Jena/Sesame etc to get transaction support at the database 
engine level as indicated by Ted on stack overflow …

Re: [Virtuoso-users] Adding a public SPARQL endpoint

2016-11-08 Thread Hugh Williams

Hi Arun,

Where are you accessing the docket AMI from via HTTP , I assume a machine 
remote to it ?

In which case the “vhost” value should be the actual hostname or cname of the 
docker you want the /sparql endpoint to be accessible on, as “localhost” is not 
accessible from a remote machine for which localhost would be itself.

Re: [Virtuoso-users] increase group_concat size

2016-11-07 Thread Hugh Williams

Hi Roland,

Unfortunately that limit can't be change  as it's at the very base levels of 
the runtime, development indicate.

What is the use case you have that requires such a large GROUP_CONCAT size ?

Re: [Virtuoso-users] [VOS7] Text Search

2016-11-07 Thread Hugh Williams

Hi 

What happens if you just remove the resource type triple pattern ? As rdf:type 
is very expensive due to its nature, as in RDF_QUAD table you are going to have 
many members (or participants) in the rdf:type relation that have to be 
evaluated whenever its used in a query, hence the overhead. Or rather than 
rdf:type which hits instantiation of all class instances, a query can simply 
negate this cost by focusing on a distinct selection of attributes in the query 
dataset which is then evaluated for solution production.

To my knowledge the Virtuoso Anytime query feature was only ever implemented

Re: [Virtuoso-users] [UTF-8 Encoding] Problems with utf-8 encoding while doing full text search in sparql query

2016-10-24 Thread Hugh Williams

Hi Taemo,

Does this error occur when the query is run against the /sparql endpoint 
directly ?

Note also the following documentation on wide char support in the Free-Text 
index when handling accented characters:


http://docs.openlinksw.com/virtuoso/virtuosotipsandtrickscontrolunicode3/

Note of if this will help with you oriental char sets though, but you can try 
setting the:

[I18N]
XAnyNormalization=3

in the INI file as it is not set current and thus defaulting to 0 …

Hi Fred,

You can enable Virtuoso query logging as detailed at:

http://docs.openlinksw.com/virtuoso/ptune/

in the "Query Logging” section where many metrics on queries,  profile,

<http://support.openlinksw.com/support/online-support.vsp> 

detailing the issue and what version (virtuoso-iodbc-t -?) is being used etc. 
The open source version (virtuoso-t -?) would also be useful to see for

You simply load then in the new Virtuoso instance with the available RDF Bulk 
Loader, which supports the loading of nquad files as detailed at:

http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtBulkRDFLoader

being nquad format the graphs name is in included for each triple (ie gspo) , 
thus each will be loaded into the same graph name as it was dumped from ...

Hi Nikolaos,

We shall look into this …

Please note also the following document on Virtuoso Timezone-less data handling:

Re: [Virtuoso-users] VirtuosoDataSource fault-tolerance

2016-10-06 Thread Hugh Williams

Hi Daniel,

All the Virtuoso Data Access Clients for JDBC, ODBC, OLEDB, ADO.Net, Sesame, 
Jena etc support round robin connections for automatic fail-over and load 
balancing ie HA as detailed at:

http://docs.openlinksw.com/virtuoso/dataccessclientsconfailandbalance/

As this is in the client it can be used with Virtuoso server instances  of any 
form ie open source , commercial, scale-out cluster etc. provided the nodes are 
known/considered to be in sync and hence can service user requests …

Best Regards
Hugh Williams

documentation at:

http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtTipsAndTricksCORsEnableSPARQLURLs

as this works for me …
