Any Software impact when applying IBM APAR OA54807?
We would like to know does CA Datacom - AD will get impacted by applying the IBM APAR OA54807.
It says in the APAR as following ACTION: Software must no longer reference the IHAPSA field PSASTAK. With this PTF, PSASTAK is no longer the beginning of the normal FRR stack. PSACSTK is an existing pointer to the beginning of the normal FRR stack. Software that references PSASTAK must be converted to use PSACSTK as the pointer to the normal FRR stack.
1- Apply service as noted in the dependency hold and any related service from Independent Software Vendor products to correct references to PSASTAK.
2- Scan code for software developed by your installation for references to PSASTAK.
3- Convert references of PSASTAK to use PSACSTK as a pointer to the normal FRR stack.
What you might see: Software that continue to reference PSASTAK may experience ABEND0C4 and other symptoms after this PTF is applied..
z/os, CA Datacom/DB or AD 14.0 and higher
Operating System control block PSA was affected by IBM APAR OA54807.The field in the control block called PSASTAK was specifically changed.
Since Datacom/DB does not reference the field, it should not be impacted by this APAR.
