Lost locks recovery

The failure of a coupling facility lock structure that cannot be rebuilt by VSAM creates the lost locks condition.

The lost locks condition can occur only for data sets opened in RLS mode. A data set can be made available for general use only after all the CICS® regions that were accessing the data set at the time of the lock structure failure have completed the process known as lost locks recovery.

Issue the IDCAMS SHCDS LISTSUBSYS(ALL) command to display the lost locks and the owners of those locks.
