[grp1260]

Hi All

            I am new to the alfresco. I have downloaded Alfresco-Labs-3b-OOo-Setup from sourceforge site and i have installed in my machine. It installed properly. while deploying also it has deployed the properly. i am using the derby database. While try to do some customization on Create Content Wizard, i am facing the error "java.lang.OutOfMemoryError: PermGen space" in tomcat. And it is getting disconnected due to above error. Please provide the proper solution to come out of this probelm. I tried the solutions provided in the forum on above mentioned problem but nothing was working, it might be the way i approaching to correct it is not the proper way. please provide the correct approach to resolve the solution.Please do the needful.


Thanks
Prasad.

The first thing for you to do is to post your JAVA_OPTS settings, so that we know what you have tried. Then let us know what environment you are running in.
Then check that your JAVA_OPTS actually has been picked up, you can do this by looking in the Administration Console, System Information and then System Properties. Check for eaxmple heap size.

Here is some mor info on JVM tuning and PermGen: http://wiki.alfresco.com/wiki/JVM_Tuning

It looks like you have not updated the JAVA_OPT.
Edit alfresco.bat in your installation folder, look for JAVA_OPT=
Try these setting (depending on your memory)
set JAVA_OPTS=-Xms256m -Xmx1024m -Xss96k -XX:MaxPermSize=256m -server

I am on linux32, had the same error, following http://www.jroller.com/agileanswers/entry/preventing_java_s_java_lang I set permsize and maxpermsize in java_opts to 512, which seems to work for me.

Modify JAVA_OPTS variable in Tomcat to ${ALF_HOME}/tomcat/bin/setenv.bat file. This file looks like to:


set JAVA_OPTS=-Xms256m -Xmx1024m -Xss96k -XX:MaxPermSize=256m -server 

set JAVA_HOME=C:\1BPMS-~1\alf34c_1\java 

set JAVA_OPTS=%JAVA_OPTS%

I had the same error, and switching from HotSpot to Resin fixed it (it was on a Windows server).
It might not work in all cases.
Resin performs garbage collection on PermGen, while HotSpot does not.

Hope this helps,
