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.
