Defining CQS parameters

The CQSIPxxx, CQSSLxxx, and CQSSGxxx members of the PROCLIB data set must be updated to enable shared queues.

To enable shared queues, define the following CQS parameters:

  • CQS initialization parameters in PROCLIB member data set CQSIPxxx.
  • CQS local structure definition parameters in PROCLIB member data set CQSSLxxx (for local structure definition). These definitions apply only to a single CQS.
  • CQS global structure definition parameters in PROCLIB member data set CQSSGxxx (for global structure definition).

    You must define one of each of these parameters for each structure pair. All of the CQSs that share queues must have the same values specified in the CQSSGxxx PROCLIB member data set. If they differ, only the first CQS connects to the structure, and the others fail.

  • Execution parameters (optional).

    If you do not specify ARMRST=, CQSGROUP=, SSN=, STRDEFG=, or STRDEFL=, CQS retrieves the values that are specified in the CQSIPxxx PROCLIB member data set.
