IMS restart and Fast Database Recovery processing for HALDB Online Reorganization

When an FDBR takeover occurs, IMS backs out all uncommitted changes for these reorganizations to the most recent sync point, closes the partition, and unauthorizes the partition.

After the FDBR terminates, the failed IMS system no longer has ownership of the online reorganization. The online reorganization can be resumed by issuing the command INITIATE OLREORG on either another IMS system or on the failed IMS system after it is restarted.
