       JVM Heap Size

       JVM means Java Virtual Machine.
       It is a memory in the web server where live and dead objects resides.
       If dead objects are more performance will degrades.
       PeopleSoft recommend the JVM Heap Size 512MB or Higher.

       Heap Size can be manually edited setEnv.cmd 

       Location of setEnv.cmd file
       PS_HOME\webserv\<Domain>\bin\setEnv.cmd

      In 8.50 Windows XP 32-bit
      SET JAVA_OPTIONS_WIN32 = -jrockit -XnoOpt -XXnoJITInline -Xms512m -Xmx512m
      -Dtoplink.xml Platform= oracle.toplink.platform.xml.jaxp.JAXPPlatform

      In 8.54 Windows
       SET JAVA_OPTIONS_WIN= -jrockit -XnoOpt -Xms512m -Xmx512m
       -Dtoplink.xml.platform=oracle.toplink.platform.xml.jaxp.JAXPPlatform

      For Administration Servers adjust JVM Heap size add the environment variable

      JAVA_OPTIONS_ADMINSERVR= "-Xms512m -Xmx512m"
