Revalidating mirrored object sets

The online method is described in the following sections. For more information about using ARMBGPV, see the BMC AMI Recovery Manager for Db2 documentation.

The revalidation procedure automatically verifies the mirroring status of the system resources and reports mirroring exceptions when it revalidates a object set. System resources are revalidated once per revalidation job, regardless of how many object sets are being revalidated. Before generating disaster recovery JCL, you should revalidate mirrored object sets to check the recoverability of objects and to verify mirroring status.

To revalidate mirrored object sets

1. From the main menu, select Option 1, Application object sets to display the Object set List panel.
2. Enter an object set name or wildcard pattern to display a list of object sets to revalidate.

3. Type R next to a single object set (or RA to report on all displayed object sets).The Batch Object Set Report Options panel is displayed.

   Option	Value
   Report type	1. Revalidation
   JCL Type	2. DR

   Warning

   Important

   The Mirror System option on this panel generates the REVALIDATE MIRROR SYSTEM syntax of ARMBGPV. You do not need to specify it if you are revalidating a mirrored object set because the mirrored system resources are automatically revalidated when a mirrored object set is revalidated. You can use this option if you want to revalidate mirrored system resources at the same time you are revalidating a nonmirrored object set or if you have no mirrored object sets at all (just a mirrored subsystem).

   The second Batch Object Set Report Options panel is displayed.

5. On the second Batch Object Set Report Options panel, set the following values:

   Option	Value
   Recover to	4. Restart RBA/LRSN
   Backout	2. No

6. On the JCL specification panel, type a data set name and press Enter to generate the revalidation job and submit the job.Mirroring exceptions for subsystem resources are written to the ARMXCEPT file. If mirroring exceptions are found for application data sets, information messages are written to ARMPRINT.

   Warning

   Important

   DEFINE NO objects are identified as mirroring exceptions, but they are given a status of DEFER, which does not interfere with mirror recovery.
