Backing up the WebSphere Application Server for z/OS system

This topic discusses methods for backing up configuration and data for the WebSphere® Application Server for z/OS® system.

About this task

Use the following guidelines to back up parts of your WebSphere Application Server for z/OS system.

Procedure

  1. Back up the HFS that contains your WebSphere Application Server 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 your 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 your own application executable files, databases, and bindings.
  6. If you wish to back up a single server, you can use the export/import function in the Administrative Console. For details on how to do this, see the assembling applications information.
