Example 2: Automated drop recovery of a partitioned table space

For this example, assume that a table space that should have been dropped from your test environment was mistakenly dropped from your production environment. You need to recover this table space, and you want to use 

BMC AMI Recover

 to create output image copies of the recovered table space.

The following information is available for the recovery:

  • Table space name: ACCTGTS
  • Database name: ACCTGDB

Step 1: Create the automated drop recovery job for a partitioned table space

Specify the values to recover the table space as shown in the following example.

Use the procedures described in Recovering-dropped-objects.

When you specify a single object to be recovered, and that object is a table or table space, Log Master displays the Options field under Specify Dropped Object(s). To display a panel on which you can define the output image copies, type E in the Options field.

Specify the values as shown in the following figure. Notice that you type 0 in the Partitions in the table space field. This value causes BMC AMI Recover to create one output image copy that contains all of the partitions of the table space, instead of one image copy for each partition.

Step 2: Review the JCL for an automated drop recovery of a partitioned table space

After you save the work ID and generate the JCL, review the job.

The generated JCL contains multiple job steps, and, if necessary, you can edit the JCL to adapt it to your environment. For example, you can stop or restart the automated drop recovery action between job steps. The following figure shows an example of the JCL created for this purpose.

Results of the job to recover a partitioned table space

After you submit the automated drop recovery job, Log Master and BMC AMI Recover create the table space, recover data into it, gather statistics on the table space, rebind any application plans that were invalidated when the table space was dropped, and take the table spaces out of check pending status.
