After a core dump, heap dump, or java dump is created, by default, the dump will reside in the ${WAS_INSTALL_ROOT}/profiles/your_profile directory. This usually is not perferred, as this can cause the profile directory to eventually run out of disk space.

You can specify a custom location for the core/heap/java dump files to be written to, at Servers > Server Types > WebSphere application servers > your application server > Java and Process Management > Process definition > Environment Entries, and create the following keys where the value is the directory where the core/heap/java dump will reside.

• IBM_JAVACOREDIR
• IBM_HEAPDUMPDIR
• IBM_COREDIR

You will need to restart the application server for this change to take effect.
