Re: [basex-talk] Running BaseX under Tomcat on a commercial Java hosting provider

[Christian Grün]

Michael,

Thanks a lot for the entertaining post! I hope your journey was not
too frustrating ;) I will have some more thoughts on the hurdles you
have encountered. Regarding user management, I hope we have made
things easier with BaseX 8 and upwards. Maybe the major advantage now
is that the permissions can be edited as (...surprise...) XML.

All the best,
Christian

Re: [basex-talk] AUTOOPTIMIZE - was true now false

[Etanchaud Fabrice]

Hello James,

Did you set AUTOOPTIMIZE to true BEFORE database creation ?
How did you set the option ? in the db:create call, or as a SET/CREATE DB pair ?

I don't have this problem with 8.3.1

Best regards,
Fabrice

Objet : [basex-talk] AUTOOPTIMIZE - was true now false

Hello,

I'm trying out AUTOOPTIMIZE for the first time and I'm not getting what I 
expect.

Running: BaseX 8.3 beta ec9b627

A new database is created with a single document which has TEXTINDEX, 
ATTRINDEX, UPDINDEX and AUTOOPTIMISE all set to true.

This is what INFO DATABASE shows (as I expect):

Indexes
 Up-to-date: true
 TEXTINDEX: true
 ATTRINDEX: true
 FTINDEX: false
 TEXTINCLUDE:
 ATTRINCLUDE:
 FTINCLUDE:
 LANGUAGE: English
 STEMMING: false
 CASESENS: false
 DIACRITICS: false
 STOPWORDS:
 UPDINDEX: true
 AUTOOPTIMIZE: true
 MAXCATS: 100
 MAXLEN: 96

Now I add a new document (or more than one) to the database. I expect that 
Up-to-date will still be true and that AUTOOPTIMIZE will still be true. But 
what I see is both are now false:

Indexes
 Up-to-date: false
 TEXTINDEX: true
 ATTRINDEX: true
 FTINDEX: false
 TEXTINCLUDE:
 ATTRINCLUDE:
 FTINCLUDE:
 LANGUAGE: English
 STEMMING: false
 CASESENS: false
 DIACRITICS: false
 STOPWORDS:
 UPDINDEX: true
 AUTOOPTIMIZE: false
 MAXCATS: 100
 MAXLEN: 96

Perhaps this is the expected behaviour and I've misunderstood AUTOOPTIMIZE? Or 
is there a bug?

Many thanks, James

Re: [basex-talk] AUTOOPTIMIZE - was true now false

[Christian Grün]

Hi James,

maybe this is due to the beta version you are working with? I just ran
the following command script with BaseX 8.3.1...

set updindex true
set autooptimize true
create db name
add to x.xml 
info db
close

...and the up-to-date continues to be "true" after the update.

Hope this helps,
Christian

[James Ball]

Hi Christian,


> maybe this is due to the beta version you are working with?

That is easy to test - and I will do that. I just wanted to make sure I hadn’t 
misunderstood what I *should* see. I will let you (and the list know) the 
outcome of my test. 

Many thanks, James

[basex-talk] XML Prague: Little Update

[Christian Grün]

Hi all,

We are currently assembling the talks for our XML Prague User Meeting.
You will soon find more information on our Lanyrd conference page [1].
For example, it’s not settled yet if the meeting will take place in
the morning or afternoon (afternoon would be our favorite).

We are still looking for speakers; please let us know if you are interested!

All the best,
Christian

Re: [basex-talk] Sizing BaseX Server

[Dirk Kirsten]

Hello Christophe,

that's easy: The more you got, the better it is ;)

More serious: It is hard, if not impossible, to tell. This very much
depends on your use case and how you intend to use BaseX in your
process. As a traditional database and having lots of read/write access,
you are most likely I/O bound. However, you can also do complex
operations using XQuery, so you could be CPU bound.

I find it almost always beneficial to use SSDs instead of traditional
HDDs, but again: If you never touch the disk at all, this wouldn't make
a difference (but it also decreases the BaseX startup time, which is nice).

The use cases just differs to much for BaseX - you can use BaseX
embedded into your smartphone application or on a large zServer, so it
is really though to give a general advice. For a practicable approach I
would always recommend you run your application at some standard server
and take a look using Java profiling where BaseX is bound and then
increase the according component.

Cheers
Dirk

Re: [basex-talk] Sizing BaseX Server

[Dirk Kirsten]

Hello Christophe,

I would see having a virtual machine as a big plus, not a negative. So
in case you really see a bottleneck you could simply demand more CPU,
RAM or whatever from your hosting provider and it will be a matter of
clicks instead of actually changing your hardware.

Cheers
Dirk

Re: [basex-talk] Sizing BaseX Server

[Christophe Marchand]

Ok, thanks a lot, Dirk. I had the same feeling, SSD, lot of RAM, big 
procs, etc...


The problem I have is the server will be a virtual machine, and I have 
to give sizing infos to infra to let them provision VMs...


Thanks again,
Christophe
