[xwiki-users] Heap size errors with new XWiki installation on jetty and oracle 11g
Hi, I recently set up a new XWiki instance, on a windows server, hosted in Jetty with the Database on Oracle 11g. After starting the server there was a "blank wiki shell", I was prompted to install the Enterprise xar which I did. It seemed to install correctly, I could create a user and log in etc. But I keep on experiencing heap size errors. I reached the point where I had allocated 2Gb memory, and it is still freezing up with heap errors. Has anyone experienced the same and managed to solve it, or got any ideas on how to isolate the problem? My configs are as follows: Java 6 64 bit Windows 2000 Server Jetty 7 Wrapped as a service with apache-commons-daemon (procrun). Thanks for listnening, Neil.
Hi, I didn't experience this kind of issue. Could you tell us the XWiki version you set up ? The problem may come from Java 6 on Windows 2K (that is very old). Maxime 2011/7/8 Neil Crow <[email protected]>:

Hi Maxime, I don't remember the version number exactly, and i don't have in front of me right now. But it was the latest stable version as of monday last week when i downloaded it. Neil On 9 Jul 2011 12:53, "Maxime Sinclair" <[email protected]> wrote:

Are you sure it is heap memory, and not PermGen? Are you sure the memory setting is taken into account, or is it passed to the wrong script that doesn't forward it to the Jetty process? Normally 500M should be enough for running XWiki without problems.
Sorry Dumitriu, You are absolutely correct. I was typing from my memory and not looking at the screen. It is permgen. In process explorer (sysinternals) I was seeing the java process, underneath the service exe process had 2Gb allocated. Neil. On 9 Jul 2011 17:56, "Sergiu Dumitriu" <[email protected]> wrote:

Sorry again Sergiu, Thanks for pointing out the perm gen. I fixed the problem by adding the following command line switches: -XX:MaxPermSize=128M -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled I also set my heap size bzck down to 512M.
