FDBR post-recovery

When recovery is complete, all shared databases and areas are available to other sharing IMS subsystems in the sysplex. You can restart the failed IMS subsystem at any time.

During IMS restart, IMS does the following to complete recovery:

• Writes updates for shared VSO areas to DASD
• Recovers nonshared DEDB areas that were not tracked by the FDBR region
• Recovers MSDBs

After the IMS subsystem is running, you can reestablish tracking by the FDBR region by issuing the z/OS® STARTfdbrproc command.
