JES2 new Function (STAC Queue Corrupted)

ITAP-SSSE z/OS JES2 support, suggested that we submit a RFE, requesting that the development team introduce a new function in JES2 so that the STAC queue is verified when a STATUS/CANCEL SSI call is being handled and if queue error is detected, the issuer of the call would be notified via a new RC.

the suggestion was given in the scope of the PMR 63391,001,822 and 64047,001.822, that report performance problems after corruption in STAC Queue.

..... I have discussed with development.
They do agree to have some RAS enhancements (Reliability/
Availability/Serviceability) to a future release of JES2
to let the issuer of the STAC SSI call be aware the STAC
queue have been corrupted.
To make this official, I would suggest you submit an RFE
through this WEB site:
.
To recap, the enhancement would be to introcuce new function
in JES2 so that the STAC queue is verified when a
STATUS/CANCEL SSI call is being handled and if queue error
is detected, the issuer of the call would be notified via a
new RC......


Another enhancement that we would like to suggest, was to evaluate the possibility of refresh the STAC queue via a JES2 hotstart.

.... The STAC queue resides in a dataspace (JES2STAC) and the only
way to refresh the STAC queue is via a JES2 warmstart
(meaning an IPL). A JES2 hotstart will not rebuild the
dataspace (JES2AUX address space maintains the dataspace on a
hotstart).....
