If your environment includes programs like RMF™, JES3, or DB2®, you may have to take their requirements into consideration when setting up SMF.
If SMF is processing records for DB2, the volume of data can be quite large. You must ensure an adequate number of VSAM buffers at initialization and sufficiently large SMF data sets.
If you are running a JES3 complex or using RMF, you might need to allocate larger data sets. If DASD space is severely limited in your installation, you might have to dump the data sets more frequently. The same considerations apply if you are using RACF® and auditing many security-related events.
