Weblogic 10.3.6 or Later

weblogic.application.ModuleException: java.lang.OutOfMemoryError: GC overhead limit exceeded

This error can be caused due to the lack of memory for java heap. To solve this problem please follow below steps.

Please note that, raising memory/heap size can not be enough everytime, find the root cause of what process/code are using most of the memory and why.

To change the WebLogic JVM heap size:

1. Open the setDomainEnv file in a text editor.

Easy way to find “setDomainEnv”. Search file under base directory

find /u01/app/middleware -name setDomainEnv.sh

/u01/app/middleware = base directory of the weblogic

or

Find directory “…/user_projects/domains”

/u02/app/oracle/middleware/user_projects/domains/Bordro/bin/setDomainEnv.sh

2. Search for this comment line:

# IF USER_MEM_ARGS the environment variable is set, use it to override ALL MEM_ARGS values

3. Immediately after the comment line, add one of these lines:

export USER_MEM_ARGS=”-Xms128m – Xmx8192m ${MEM_DEV_ARGS} ${MEM_MAX_PERM_SIZE}”

4. Save the file.
5. Re-start Weblogic Server or Managed server, you deployed your application.
