CA Top Secret and the SYSPLEX XES Function

The XES data‑sharing feature lets you define a primary and an alternate list structure in the coupling facility.

If this feature is enabled, CA Top Secret attempts to obtain the requested data from the coupling facility before any physical I/O is performed. If the requested data is obtained from the coupling facility no I/O is performed. Thus saving the time from having to do the actual I/O to the database.

If you are using the CACHE facility with CA Top Secret, the cache call is performed prior to any call to the coupling facility. If the data is found in the CACHE, no calls to the coupling facility or the I/O to the database are performed.
