WebSphere Application Server for z/OS makes extensive use of the /tmp directory.
You can use the df -kP /tmp shell command to show the number of available 1K blocks in the /tmp directory HFS. Divide the number of available 1K blocks by 1024 to determine the number of megabytes of free space.
If your /tmp directory resides in a permanent read-write HFS, use the confighfs command in /usr/lpp/dfsms/bin to extend it as necessary. For example, the following command will add an additional 10 MB of space to the HFS in which /tmp resides:
/usr/lpp/dfsms/bin/confighfs -x 10m /tmp
If your /tmp directory resides in a temporary file system (TFS), modify the MOUNT statement in BPXPRMxx that defines it to add additional space. To define a 20 MB TFS and mount it at /tmp, for example, use the following MOUNT command:
Also, determine whether these datasets are in the system link pack area (LPA) or link list. Record this information on the worksheet.
Each WebSphere Application Server for z/OS address space should have a region size of at least 512 MB. All WebSphere Application Server for z/OS cataloged procedures are shipped with a default of REGION=0M.
