A z/OS batch application called ORDRPROC processes order messages. Each message is 30 to 40 KB in size. In the past, a non-shared local queue was used and the application was always run on the same single LPAR.
As part of a 24/7 high availability project, the queue is to be converted into a shared queue, so the processing can take place on any of four LPARs, but it is critical that the messages are processed by only one instance of the batch server program at a time.
The shared queue is to use an existing Coupling Facility structure named BATCHMSGS which is configured to offload messages larger than 24 KB to shared message data set (SMDS).
In addition to setting QSGDISP(SHARED), which attributes (amongst others) must the system administrator use within the define QLOCAL command for the new shared queue to support these requirements?
A. OFFLOAD(SMDS) SHARE
B. DEFSOPT(SHARED) NOTRIGGER
C. CFSTRUCT(BATCHMSGS) NOSHARE
D. STGCLASS(SHARED) PROCESS(ORDRPROC)
