CICSPlex® SM uses a cached copy of RACF information in order to reduce unnecessary I/O to the RACF database. When you change a RACF definition, you will, in some situations, need to force the CMAS to refresh the cached information.
Perform the following steps to refresh the general resource profiles in the cache.
A CMAS stores security information for a userid in the cache when it performs a security check. By default, the information is retained in the cache until the user has remained inactive in the CMAS for the time specified by the SECTIMEOUT CICSPlex SM parameter, and the CMAS has performed a userid timeout check.
Whenever a change is made to a userid (for example, with the CONNECT, REMOVE, ALTUSER, or DELUSER commands), the change becomes visible when the CMAS discards security information for the user form the cache.
