Tuning the Session Cache

To help you tune the resource cache, CA Top Secret provides functions to display cache utilization on a global system level and on an individual terminal level. You should compare the number of times that overflows occurred to the number of validations requested. Some cache overflow is reasonable, since a small set of users might access many different resources in a CICS system. However, if no overflows are noted, then the cache size is probably too large for the kind of resource validation activity taking place in the CICS system.

Note: If the cache size is too small, excessive host resource validation is performed. Making the cache too large can result in excessive operating system paging.
