Before remote copy mode is resumed, the remote copy pair must be checked for data differences. After the tests the changes to the source unit are as a rule accepted and replication is resumed.
Actions on the standby system
> | Terminate the application on the target units. |
Actions in the local system
> | Keep the changes on the source units (i.e. all changes made on the target units during the recovery tests are discarded).

The WAIT operand specifies whether the command waits for synchronization to be completed (WAIT=*UNTIL-SYNCHRONIZATION) or not (WAIT=*NO). This simplifies the programming of test procedures for recovery because extensive queries regarding the synchronization progress of the remote copy pair are unnecessary.
