Back up the WAS for z/OS system

This topic discusses methods for backing up configuration and data for the WAS for z/OS system.

Use the following guidelines to back up parts of the WAS for z/OS system.

  1. Back up the HFS containing the WAS for z/OS configuration (e.g. WebSphere/V5R0M0/AppServer).

  2. Back up the RMDATA log for Resource Recovery Service (RRS). Otherwise, a failure could force you to do a cold start of RRS.

  3. Set the ARCHIVE log retention period to one day.

  4. Incorporate the following items in the normal backup procedures:

    • WebSphere Application Server for z/OS procedure libraries.

    • WebSphere Application Server for z/OS load libraries.

    • The directory where WebSphere Application Server for z/OS run-time information is written. The default is /WebSphere/V5R0M0.

  5. Back up our own application executable files, databases, and bindings.

  6. If we wish to back up a single server, we can use the export/import function in the Administrative Console. For details on how to do this, see the assembling applications information.
