Executing system recovery simulation JCL at the local site

The disaster recovery simulation JCL simulates the recovery of the BSDS and logs. Any steps that are disruptive to the system are commented out, and the Db2 catalog and directory are not recovered.

For more details, see Task-6-Generating-the-disaster-recovery-simulation-JCL.

The flow of the system recovery simulation JCL is determined by the options that you specified. If more than one job is created within a phase, BMC AMI Recovery Manager includes job steps that synchronize job execution without requiring manual intervention.

The following table shows the operations that are performed for each non-data-sharing subsystem. Whether they are performed on only one or on all members of a data-sharing object set is shown in parentheses. When the BSDS or logs are specified, these are work copies.

Important

If you have the Recovery Management for Db2 solution, recovery data is collected throughout the recovery and then consolidated and reported at the end.

Functions accomplished during the Initialization Phase

Step	Systems without remote hardware mirroring	Systems with level 1 remote hardware mirroring	Systems with level 2 remote hardware mirroring
1	Delete and define each BSDS work copy (all).	Delete and define each BSDS ¹ work copy (all).	Delete and define each BSDS ¹ work copy(all).
2	Delete and define each active log work copy (all).	REPRO new BSDS work copy from the mirrored copy ¹ (all).	REPRO new BSDS work copy from the mirrored copy ¹ (all).
3	Recover each BSDS work copy from the last archive log data set (all).	Delete and define each active log ¹ work copy (all).	Delete and define each active log ¹ work copy (all).
4	Use Change Log Inventory to rename the archive log data set work copies (if required) and add the last copy of the archive log data set work copy to the BSDS work copies (all).	REPRO new active log work copies from the mirrored copy ¹ (all).	REPRO new active log work copies from the mirrored copy ¹ (all).
5	Use Change Log Inventory to generate the CRCR (all).	Print log map (all).	Print log map (all).
6	Use Change Log Inventory to add the active log work copies to the BSDS work copy. Optionally, initialize all but one of the active log data set work copies (all).	Not applicable	Not applicable
7	Print log map (all).	Not applicable	Not applicable

^{1Required only if your system is mirroring just one copy of the BSDS and active logs (HWCOPY n option).}
