Resource Validation and Auditing › CICS Cache

CICS Cache

A CICS resource cache is an in-storage list of secured resources that a user has been allowed to access. The CICS cache reduces the number of host resource validation calls.

All successful resource checks for a user are cached. The cache exists for the life of the transaction. The CACHE box size is fixed at 512K. No auditing occurs for subsequent executions once the first transaction has been verified.

Two types of CICS cache are available:

Transaction life cache

Keeps a resource in the cache buffer for the life of the transaction. Once the transaction ends, the cache buffer is cleared. This is the default.

Session life cache

Keeps the resource in the cache buffer for the life of the signed on session. The cache is maintained until the user signs off. This provides improved performance since the authorization will be satisfied by the TSS CICS cache check. Set by control option OPTIONS(28).

Note: In addition to the time and date permissions, if auditing is in effect, only the first access for a particular resource is logged to the Audit Tracking file.
