Hi,

I want to change Heap memory size of liberty's JVM. But I can not know how to do this.

I can see used heap memory via admin Center. But it is not editable.

The Liberty JVM settings can be updated in the server.startup.bat or (probably) server.startup.sh script in the <JAZZ_HOME>\server directory:

e.g: 
...
set JAVA_OPTS=%JAVA_OPTS% -Xmx4G
set JAVA_OPTS=%JAVA_OPTS% -Xms4G
set JAVA_OPTS=%JAVA_OPTS% -Xmn512M
set JAVA_OPTS=%JAVA_OPTS% -XX:MaxDirectMemorySize=1G
set JAVA_OPTS=%JAVA_OPTS% -Xgcpolicy:gencon
set JAVA_OPTS=%JAVA_OPTS% -Xcompressedrefs -Xgc:preferredHeapBase=0x100000000
...
