CSALIMITS (MWE): Specifying maximum number of NOWAIT MWEs per address space

Explanation: MWE(#mwes) is an optional subparameter of the CSALIMITS parameter specifying the maximum number of NOWAIT MWEs submitted by a single address space that is to be kept on the CSA queue until completed. NOWAIT MWEs in excess of the maximum number will be removed from the CSA queue as soon as they are copied into the DFSMShsm address space. For #mwes, specify a 1-to 4-character decimal number indicating how many NOWAIT MWEs per address space are kept on the CSA queue until completed. To limit the number of NOWAIT MWEs kept on the CSA queue, specify a number between 0 and 8191. If you specify 0, all NOWAIT MWEs are removed from the CSA queue as soon as they are copied into the address space of DFSMShsm. If you specify 8192 or higher, the number of MWEs to keep on the CSA queue per address space is limited only by the amount of CSA available, as specified in the MAXIMUM subparameter.

SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.

SETSYS default: None.

DFSMShsm default: If you do not specify this subparameter on any SETSYS command, the DFSMShsm default is 4.

Note: If DFSMShsm is inactive, the NOWAIT MWEs will not be removed from the CSA queue. In that case, the number of NOWAIT MWEs submitted by all address spaces that will be added to the CSA queue is controlled by the INACTIVE subparameter.
