hi

JAVA_OPTIONS="${JAVA_OPTIONS} -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/path/OOM.log"

i've used the above command in startweblogic.sh.

1.Please check the syntax whether it is correct or not?

2.sending to a file.log will redirect ??

3.when OOM occurs heapdump will be generated. how long will it take and will it effect any load ??

thanks.

and your changes should go in setDomainEnv.sh because that is sourced by all lifecycle scripts.
When using NodeManager make sure it is configured to use scripts.
 
It is sorta covered in the JavaRanch Style Guide.
