Question:

How do you reduce I/O, CPU and decrease CPF usage in CA Top Secret?

Answer:

Implementing the SECCACHE control option to provide a cache for CA Top Secret to place security records that reflect the status of a user following a 'RACROUTE REQUEST=VERIFY' request.

The cache is managed in a common data space that can be accessed from all address spaces.

The cache increases system performance by:

  • Reducing CPU cycles in both the user and Top Secret address space required to complete subsequent RACROUTE VERIFY requests.
  • Reducing I/O against the security file when the file is shared between multiple systems.

If the main reason for implementing CPF was for performance reasons then enabling SECCACHE may allow sites to revisit that decision.
