IMS restart and XRF processing for HALDB Online Reorganization

If you shut down IMS while any online reorganizations of HALDB partitions are running, IMS suspends the reorganizations before completing the shutdown checkpoint.

After IMS restarts, IMS automatically resumes the online reorganizations. IMS resumes the online reorganization even if you specified the NOPDBO option in the DFSVSMxx member.

If IMS terminates abnormally while any online reorganizations are running, IMS dynamically backs out all uncommitted changes for these reorganizations to the most recent sync point. After IMS restarts, IMS automatically resumes the online reorganizations.

When an XRF takeover occurs, IMS automatically resumes the online reorganizations on the new active IMS system.

You can also use the OPTION(REL) parameter of either the INITIATE OLREORG command or the UPDATE OLREORG command, or code RELOLROWNER=Y in the DFSDFxxx member of the IMS.PROCLIB data set, to instruct the IMS system to release ownership if the system terminates (either normally or abnormally) before completing the reorganization. Using one of these options allows another IMS system to resume the suspended reorganization.
