Recovering the Db2 subsystem

You can set up a batch job that will recover the Db2 subsystem to a previous point in time.

1. On the DB2 Administration Menu (ADB2) panel, specify Z, and press Enter.
   The System Administration (ADB2Z) panel is displayed.
2. Specify option SR, and press Enter.
   The System Restore (ADB2ZSR) panel is displayed, as shown in the following figure.

     BP - Change batch job parameters specified                                    

3. Specify values for the DSN for Restore System JCL and Member name fields to identify where the generated JCL is to be stored, and specify values for any other appropriate options.

   Depending on the level of Db2 that you are using, some of the fields on this panel might be hidden. See the online help for a description of the fields that are displayed.

4. Press Enter.
   Db2 Admin Tool displays the generated JCL for the job, which invokes the RESTORE SYSTEM utility.
5. Save the JCL for the batch job.
   Restriction: The batch job cannot be submitted directly after it is created. It cannot be run from Db2 Admin Tool.
