Question

I am running following script for starting my bea weblogic workshow 8.1.4, workshop start properly and function very well

C:\bea\weblogic81\workshop
C:\bea\jdk142_05\bin\javaw.exe
-XX:-UseThreadPriorities -Xmx512m -Xms512m -Xss256k -client -Dbpelexport.java.home=”C:\bea10.3\jdk160_05\”
-Dsun.io.useCanonCaches=false -Dsun.java2d.noddraw=true -Dsun.java2d.d3d=false -Djava.system.class.loader=”workshop.core.AppClassLoader”
-cp “C:\bea\weblogic81\workshop\wlw-ide.jar”
workshop.core.Workshop

But when i start exporting my process(means these lines come in picture -Dbpelexport.java.home="C:\bea10.3\jdk160_05\") I am getting following error

My system has 3 GB of RAM.

is there any way i can supply memory parameters to jdk1.6 java.exe also in the same script.

suggest me something…

Answer 1

Modify the -Xmx argument to give the process more memory, such as -Xmx=2G to allow Java use 2 gigs of memory. Adjust as needed.
