Recovery without DBRC
If you perform any recovery-related actions offline when DBRC is not running, such as making database image copies, problems could arise because DBRC would not be notified of the changes in status.
Therefore, DBRC must be specifically informed of such changes. DBRC offers you several commands for this purpose.
Because restart is required, the Utility Control Facility (UCF) might have to be used without DBRC being active. If you use UCF for any recovery-related work, DBRC must be informed of status changes afterward.
