Issue:
Are any of the CA DADS Plus CICS r 4.0 features impacted by applying IBM APAR OA54807?
Environment:
CA DADS Plus CICS r 4.0 installed in a z/OS environment with IBM APAR OA54807 applied.  
Cause:
IBM APAR OA5407 introduces a new IEASYS Parm called OSPROTECT which specifies the operating system mode for unauthorized programs and users. 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.The PSASTAK is related to recovery management and the apar itself changes the definintion of the PSASTAK field in module IHAPSA  to PSACSTK and software continuing to reference PSASTAK can receive a S0C4. 
Resolution:
CA DADS Plus CICS r 4.0 does not reference or use the PSASTAK field so there is no impact on CA DADS Plus CICS when applying IBM APAR OA54807.
