Disaster Recovery for WebSphere Application Server for z/OS
 Technote (FAQ)
 
Problem
What are the Disaster Recovery options for WebSphere® Application Server if it must be recovered onto a system with a different system, SYSPLEX or DB2® Subsystem name?
 
 
Solution
In WebSphere Application Server 4.0 there is no way to change the system or sysplex name used in a WebSphere Application Server runtime environment. If these names must be changed because of your disaster recovery procedures, the recommended approach is to use the prepare for Cold Start process, if this is viable in your scenario.

If the prepare for Cold Start process is not acceptable, the only other alternatives are:

  • Have a recovery system with identical names to the original WebSphere Application Server system

    or
  • Reinstall WebSphere Application Server onto your recovery system with the new system and/or SYSPLEX and/or DB2 subsystem names.


Another scenario starts with the assumption that, as part of the disaster recovery, you have the same system, sysplex and DB2 subsystem names as on the original WebSphere Application Server system. If the daemon IP address is also the same, you should be able to recover your WebSphere Application Server system using all of the backed-up data described in the document "Operations and Administration" Chapter 5, "WebSphere for z/OS backup guidelines and procedures."

All of the backups must be the same snapshot of time as in your WebSphere Application Server environment. If this is not the case, your disaster recovery plan must redefine the servers, then redeploy the applications onto the newly-defined servers.
