SMFLIMxx (specifying region and memlimit values)
Use the SMFLIMxx parmlib member to specify values that are similar to several of the output fields in the IEFUSI SMF exit. These values can override the REGION of a job step, set the MEMLIMIT for a job step or cause space to be reserved in high private subpools in the private area.
The SMFLIM specification becomes active when the SMF address space is initialized, regardless of whether SMF records are being collected and recorded.
SMFLIMxx consists of a set of REGION statements. Each REGION statement has one or more filter keywords and corresponding memory attributes to be set.
Note: For more information on region size, see the section Limiting user
region size in z/OS MVS Initialization and Tuning Guide.
