Hi,
3 days ago, we took this following error at xwiki 1.8 startup. The install
is the standalone "Stable: xwiki-enterprise-installer-windows-1.8.2.exe "
with the hdsqldb database by default.
We use xwiki since 2 or 3 months and the database is large of 82Mo.
- I tried to use files of the database (replacing database folder) on
another clean standalone install, and the problem is same.
- I tried to use default database folder of clean install on my problematic
install, and it works.
- I tried to use save of my database folder (5-6 days old), and the problem
is same.
I see in error message several lines with "Cannot create
PoolableConnectionFactory (Out of Memory)" or "Caused by:
java.sql.SQLException: Out of Memory", but i need real help to understand
and fix my problem.
Please any help is welcome, thanks.

still there:

Independently of that, eliminate out of memory error from possibilities:
(1) Increase the memory on your java process. I've been running a vhosted
1.8 system happily for over a month now, nonstop, with the following
settings (YMMV, I'm running two large apps in tomcat):
tomcat 2040 0.5 60.2 1835160 1230408 ? Sl Apr03 267:28
/usr/java/default/bin/java -server -Xms160m -Xmx1024m -XX:PermSize=160m
-XX:MaxPermSize=320m -Djavax.servlet.request.encoding=UTF-8
-Dfile.encoding=UTF-8 -DjavaEncoding=UTF-8 -Djava.awt.headless=true ...
Note the gargantuan 1.2g process size... but it just keeps running... It
always eventually reaches it's 1.2g (-Xmx1024m) limit but doesn't give out
of memory errors.
(2) Check on additional customizations as needed. Increase fixed limits in
your SQL connector, or in the db it itself? For example with

need to increase: "-- max_allowed_packet=32M" ...

Thank you for your answer, but i need explanations.

(1) how to do? where can i manage theses settings?

New subject: [xwiki-users] Problem with HSQLDB Database please Help!!
Thanks,
I resolve my problem increasing limit size of java with the -Xmxsizem
parameter!
it was by default on -Xmx300m, and i need -Xmx600m.
In order to understand...i would like to know what is really loaded in
memory?
Xwiki need to load all the database in memory? all the pages with join
files? i thought one of interest of a database is to don't load all
information? Our base is still pretty small today, it means in one year we
will need 8Go of RAM? or we must change for Mysql?
Thank you for your help

(0) Restart your container. And relaunch. Check to see if this error is
still there:
Wrapped Exception: com.xpn.xwiki.XWikiException:
Error number 0 in 3:
Exception while hibernate execute Wrapped Exception: Could not create a
DBCP
pool. There is an error in the hibernate configuration file, please
review
If so, beg for additional assistance on list... (Does this error arise
from
an out of memory condition or indicate version mismatch between db and
software?).
Independently of that, eliminate out of memory error from possibilities:
(1) Increase the memory on your java process. I've been running a vhosted
1.8 system happily for over a month now, nonstop, with the following
settings (YMMV, I'm running two large apps in tomcat):
tomcat 2040 0.5 60.2 1835160 1230408 ? Sl Apr03 267:28
/usr/java/default/bin/java -server -Xms160m -Xmx1024m -XX:PermSize=160m
-XX:MaxPermSize=320m -Djavax.servlet.request.encoding=UTF-8
-Dfile.encoding=UTF-8 -DjavaEncoding=UTF-8 -Djava.awt.headless=true ...
Note the gargantuan 1.2g process size... but it just keeps running... It
always eventually reaches it's 1.2g (-Xmx1024m) limit but doesn't give
out
of memory errors.
(2) Check on additional customizations as needed. Increase fixed limits
in
your SQL connector, or in the db it itself? For example with
MySQL<http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationMy…
need to increase: "-- max_allowed_packet=32M" ...
(3) Look into logs more carefully, and run some of the queries that are
failing directly into your database. Potentially related, issues with
large
attachments:

http://n2.nabble.com/Hibernate-exception-when-trying-to-delete-attachment-t…
(4) Consult

for additional tips on Process size, turning off Monitoring, changing
cache
size, etc.

New subject: [xwiki-users] Problem with HSQLDB Database please Help!!
Hi Remi,
Remi wrote:
Thanks,
I resolve my problem increasing limit size of java with the -Xmxsizem
parameter!
it was by default on -Xmx300m, and i need -Xmx600m.
In order to understand...i would like to know what is really loaded in
memory?
Xwiki need to load all the database in memory?
No. XWiki caches in memory a maximum number of documents that you can
configure.
all the pages with join
files? i thought one of interest of a database is to don't load all
information? Our base is still pretty small today, it means in one year we
will need 8Go of RAM? or we must change for Mysql?
HSQLDB is not meant for production instances in any case. It is a
convenience distribution for testing. In a near future we will write a
warning message next to the standalone distributions (jetty + HSQLDB)
download links to state this clear and avoid any confusion.
For a production environment you will need to install XWiki in your own
servlet container and configure it to use your own database.
Please refer to
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HInstallin…
(and http://platform.xwiki.org/xwiki/bin/view/AdminGuide/ in general).
If you need, XWiki SAS (http://www.xwiki.com) can provide you hosting or
consulting to get the best out of your XWiki installation.

Jerome.
