Hi Mahari,

This can be done using the serverstartup.bat, on my windows installation, this file is found under:
C:\IBM\CLM601\JazzTeamServer\server\server.startup.bat

The lines to edit would be :
set JAVA_OPTS=%JAVA_OPTS% -Xmx4G
set JAVA_OPTS=%JAVA_OPTS% -Xms4G
set JAVA_OPTS=%JAVA_OPTS% -Xmn512M

to
set JAVA_OPTS=%JAVA_OPTS% -Xmx8G
set JAVA_OPTS=%JAVA_OPTS% -Xms8G
set JAVA_OPTS=%JAVA_OPTS% -Xmn2G

hope this helps.

Regards,
Dinesh

Odd,

It seemed to work, but now, the max is still 4GB. Not sure why.

I think you need 64bit JRE to go beyond 4G.

It's all about the answers!
