[dspace-tech] Error to tried to creating a community

2018-05-07 Thread Manuel Hidalgo 
Hi,

We finish to install dspace 6.2 but when we tried to create a community on
dspace, shows this error and not create the community.

Someone know how we can resolve that.

Thanks

Re: [dspace-tech] Error deleting a collection

2018-05-07 Thread Stanislav Orlov 
Thank you Claudia,

We started ten years ago and went through a few upgrades. I can see how 
this problem might have been created during the process, but we never ran 
into the problem until now.  If I look at foreign keys for 
community2collection table, I see this: 

Name: community2collection_community_id_fkey
Fields: community_id
Referenced Schema: public
Referenced Table: community
Referenced Fields: community_id
On Delete: NO ACTION
On Update: NO ACTION 

What do I need to do to fix this?

Stan

[dspace-tech] Re: "Distributed" DSpace

2018-05-07 Thread Mark H. Wood 
If you are running your Servlet container (e.g. Tomcat) behind Apache HTTPD 
or Nginx or some such, then you could also run that web front-end service 
on a separate host.

You may be able to load-balance across several containers behind a common 
front-end.  I haven't tried that.

Another (small) load that can be separated out is the Handle service.

DSpace used to have storage code to support keeping the assetstore(s) in 
SRB distributed storage.  I don't recall ever hearing that it was used, and 
it was recently removed.  It would have needed refactoring anyway, and SRB 
has been superseded.  It wouldn't be hard to write a Bitstore 
implementation for SRB's successor iRODS.  But before tackling that, there 
is probably a lot you can do to spread I/O load and improve throughput 
using the facilities that your OS already has, perhaps with some small 
rearrangement of hardware and physical storage.

But I'll echo the other advice in this thread:  first determine that you 
have a performance problem, and where it is.  That is not a lot of 
content.  Unless it is extraordinarily popular, you may not have any 
scaling work to do.

Re: [dspace-tech] Error deleting a collection

2018-05-07 Thread Claudia Jürgen 

Hello Stanislav,

are you using Postgres or Oracle and is this an original 4.0
installation or did you upgrade from an older version?
If you are using Postgres and did upgrade there may have been an issue
with the upgrade process.
The constraint is here:
https://github.com/DSpace/DSpace/blob/dspace-4.0/dspace/etc/postgres/database_schema.sql#L410
and was added during 1.5 to 1.6
https://github.com/DSpace/DSpace/blob/dspace-4.0/dspace/etc/postgres/database_schema_15-16.sql#L106

You may  inspect your db  for the foreign keys:
psql [YourDBName]
\d [TableName]
will show you the foreign keys.
\d community2collection

There has been an issue with the upgrade process, maybe your problem in
an aftereffect of this:
http://dspace.2283337.n4.nabble.com/Dspace-tech-running-the-15-to-16-script-td3280357.html

Hope this helps

Greetings!

When I try to delete collections in DSpace 4.0 on Windows Server 2008, I
have the following error:

org.postgresql.util.PSQLException: ERROR: constraint
"comm2coll_collection_fk" does not exist

Our PostgreSQL has a "community2collection" table with one foreign key -
"community_id" - so I don't know what needs to be done to fix it.  You help
will be most welcome.

Thanks for suggestions.

Another related question is: does anyone uses any distributed filesystem(s)
to distribute storage of the files across multiple machines ?

Re: [dspace-tech] "Distributed" DSpace

2018-05-07 Thread helix84 
Do you expect the load to be mainy page views or file downloads?

For anonymous page views, set up Varnish Cache. You can also easily
move Solr (search, statistics, oai) to a separate machine if it turns
out to receive much load.

If you expect to have many small files with a small part being
downloaded constantly, Varnish may help there, too.
In case of relatively few large files, if you happen to saturate your
drive's I/O, you can rebalance the assetstore files among several
assetstores on physically separate volumes. There seems to be a new
bitstore-migrate tool [1] in DSpace 6 to help you with that, but I
haven't tried it. It's straightforward to rebalance the assetstore
files manually, too.

So it all comes down to what turns out to be slow. But avoid
optimizing what you think may be slow. First measure, only then act
upon that.
