Applying WLS patch using BSU -java.lang.OutOfMemoryError: GC overhead limit exceeded

Posted by Sriram Sanka on July 8, 2018


If you are trying to Apply any Big Patch, while Checking for conflicts…., “BSU”  might end-up with Java Heap  Errors.

 

 

To Avoid,  Try to Increase the size in $FMW_Home/utils/bsu . Edit bsu.sh using any editor as below. 

Change the Value MEM_ARGS=”-Xms256m -Xmx512m” to MEM_ARGS=”-Xms1024m -Xmx1024m” or even bigger  and save. 

This will resolve the above issue and re-try applying the patch .

 

For more Details Ref Oracle MOS Doc:  Weblogic 10.3.6 Patching Error Using BSU – “java.lang.OutOfMemoryError: GC overhead limit exceeded” (Doc ID 2007492.1) and
