FCDSESWR

A resource name of FCDSESWR indicates a wait for an ESDS write lock.

For integrity reasons, WRITE requests to recoverable ESDS data sets must be serialized. When a transaction issues such a request, it holds the ESDS write lock for the time it takes to log the request, obtain a record lock, and write the data set record. If another transaction issues a WRITE request during this period, it is suspended until the ESDS lock is released. The lock is normally released when the WRITE completes, but may be help until syncpoint of the WRITE fails.
