Disaster recovery simulation—Db2 system resources

During disaster recovery simulation, 

BMC AMI Recovery Manager

 generates JCL to copy the BSDS and to create the proposed conditional restart control record (CRCR) in the BSDS.

Other checks on your specifications for disaster recovery are also made. However, no actual conditional restart or recovery of the catalog and directory is performed.

Important

We recommend that you review the volume specifications (especially the VOLSERS) for data sets (such as the alternative BSDS and active logs) that are generated by ARMBSRR to verify they are appropriate for your organizational standards. For example, you might not want the simulation to run on your production volumes.

BMC AMI Recovery Manager performs the following tasks for system recovery simulation:

  • During the recovery, the ARMBWDC program continually records data collection information. The ARMBRDC program processes the data collected during recoveries and stores the results.
  • ARMBSRR creates and processes the OPTIONS SIMULATE YES syntax whether you are running with DSNUTILB or

    Some content is unavailable due to permissions.

    .
  • ARMBSRR creates a dummy BSDS file. If you are using data sharing, ARMBSRR creates one dummy BSDS per data sharing member. The dummy BSDS files are named vcat.BMCBSDS1 and vcat.BMCBSDS2. All JCL that is generated at this point references the dummy BSDS file. Change Log Inventory and Print Log Maps are run against the dummy BSDS.
  • ARMBSRR prints a report that lists the copies and logs used for the recovery of each catalog and directory table space.

Important

The report is produced whether or not BMC AMI Recovery Manager is running in simulation mode. If the ARMVRPT DD statement is present, the information for this report prints to the ARMVRPT output. If the ARMVRPT DD statement is not present, this information prints at the end of the ARMPRINT DD.

You select the simulation mode in the BMC AMI Recovery Manager interface to generate JCL for system recovery simulation. The tasks that you perform for system recovery simulation vary depending on your disaster recovery procedures:

The following table summarizes the tasks required for disaster recovery simulation:

Task

Description

Reference

1

Build subsystem object sets (first time only)

2

Establish a recovery point

3

Set archive log copy options

4

Set options to generate simulation JCL

5

Generate simulation JCL

6

Execute simulation JCL

These procedures assume that you have image copies of your business applications, the Db2 catalog and directory, the BMC AMI Recovery Manager repository, and the R+/CHANGE ACCUM repository (if applicable).
