Global Enqueue for PowerExchange CDC

Global Enqueue for PowerExchange CDC

PowerExchange CDC issues only SYSTEMS-level enqueues for serializing across multiple MVS systems. To use PowerExchange CDC on multiple MVS systems, you must make use of a global serialization product such as GRS or MIM to propagate these enqueues.
If you are using a cross-system serialization product that requires you to specifically define the enqueues that need to be propagated globally, you need to know the QNAMEs issued by PowerExchange CDC.
The DB2 ECCR uses a SYSTEMS-level enqueue to prevent multiple instances of the same ECCR running. The QNAME is DB2CAPT. The RNAME is an eight-byte field, the NAME= value from the DB2 ECCR REPL2CTL control file statement CA. The SYSTEMS enqueue exists for the life of the ECCR execution.
You might need to include this information in the options for your cross-system serialization product to ensure these enqueues are properly handled.
