SIMULATE YES

You can verify that needed recovery resources are valid and available and that log apply can be done.

In simulation mode, BMC AMI Recover proceeds with all recovery activities that are not destructive. Destructive actions that could affect real database objects or recovery environment are simulated or suppressed.

There are several limitations and requirements you should take in account when you use the SIMULATE YES option:

• The SIMULATE YES option cannot be specified with the ANALYZE ONLY, or ANALYZE SCANONLY options.
• The LOGSCAN command cannot be used if you specify the SIMULATE YES option.
• Point-in-time recovery is not allowed if the SIMULATE YES option is specified.
• The requested recovery scenario can require unloading keys from the real table space (partition) if REBUILD or UNLOADKEYS is requested for the table space (partition) not recovered in the same step. Such actions will be suppressed if the SIMULATE YES option is specified.
• Objects may be in any initial status and there is no impact on the status or contents of the real database objects if the SIMULATE YES option is specified.
• No registration into Db2 or BMC tables occurs and no restarts are possible if the SIMULATE YES option is specified.
• Some options related to the suppressed or simulated actions will have no impact if the SIMULATE YES option is specified.

• In the following recovery scenarios, BMC AMI Recover creates and uses temporary data sets (SIMDBC or SIMDBD), instead of real spaces (DSNDBC or DSNDBD), for simulation:

  • Recoveries from Inline, instant snapshot, or flashcopy image copies
  • Backout, LOGONLY, or LOGAPPLY ONLY recoveries

  When you simulate recovery of inline, instant snapshot, or flashcopy image copies, BMC AMI Recover snaps the image copy into temporary data sets to process the simulation.

  When you simulate a backout, LOGONLY, or LOGAPPLY ONLY recovery, BMC AMI Recover snaps the original spaces into temporary data sets to process the simulation.

• Except when temporary data sets are required, any output activity for the spaces and output copies (including data set allocation, creation, and extension) is only simulated if the SIMULATE YES option is specified. No real I/O or requests to the system services take place. When temporary data sets are required, output activity is restricted to the temporary data sets.
• Use SIMRCVR and SIMRBLD instead of regular RECOVER and REBUILD if the SIMULATE YES option is specified.

For more information about recovery simulation, see Recovery Management for Db2 documentation. You can use BMC AMI Recovery Manager for Db2 and its online interface to generate JCL for the simulation mode for both application and system recovery.
