Task 1: Creating copies of business applications

Before you create copies of your business applications, perform the following steps:

• Create and revalidate recovery site object sets

  Consider creating a set of BMC AMI Recovery Manager object sets specifically for use in disaster recovery. You may want to name these object sets to reflect the sequence in which you want them to be recovered at the recovery site. For example:

  • DROBJECTSET1 — accounts receivable
  • DROBJECTSET2 — inventory
  • DROBJECTSET3 — order entry

  For more information on creating object sets, see Creating-and-working-with-object-sets.

  When creating these object sets, if possible, limit the number of objects in any one object set to no more than a few hundred, including both table spaces and indexes. One large object set may require significantly more time for JCL generation than is required for the same set of objects when divided into smaller object sets.

  Important

  We recommend that you create application object sets for all BMC tables that will be needed at the disaster recovery site (for example, BMC AMI Copy, BMC AMI Recover, and so on).

• Audit recoverability

  After you have created a set of disaster recovery object sets, you should run the BMC AMI Recovery Manager program ARMBGPV to audit their recoverability by using the SITETYPE RECOVERY option. You may also want to save the pick list report for future reference.

• Execute batch revalidation procedures regularly

  Schedule batch revalidation jobs for your disaster recovery object sets. It is important to verify the recoverability of object sets regularly. How often you should schedule these jobs depends on the frequency of object changes and the scheduling of your offsite backups. See Revalidating-and-reporting-on-object-sets-in-batch for more information.

• Regenerate the backup JCL after revalidation
