The OPSLOG Does Not Have to Be a DIV Data Set

The OPSLOG is not required to be a DIV data set. If you keep the OPSLOG in a data space only (that is, you do not allocate an OPSLOG data set to the CA OPS/MVS address space), then there will be no OPSLOG real storage trimming since there is no checkpoint cycle. In this case, you must use either the SRM or workload manager mechanism to control the size of the CA OPS/MVS working set. You should also ensure that there is a sufficient amount of paging space available on your page data sets to hold the paged-out OPSLOG pages.
