Directing Application dumps in WebSphere for z/OS

Sometimes when you have an application that produces a dump, you run the risk of depleting your space in the Unix System Services, USS, file system and having this affect other applications.  In order to redirect your WebSphere dumps to a pre-allocated file system, you can do the following:

In the WebSphere Admin Console...go to...

Environment -> WebSphere variables

Add a new environment variable at the Cell or Server level which ever is the highest.  The name of the variable will be _CEE_DMPTARG and the value will be the new HFS or ZFS you allocated and mounted.....i.e. /home/websphere/dumps.

Save the configuration and stop and re-start the cell and or servers.
