Question & Answer
Question
Why am I receiving EZY1293E INITAPI CALL FAILURE TRANSACTION = CSKL TASKID=nnnnnnn ERRNO= 156 ? I am running CICS Transaction Server for z/OS (CICS TS) V5.3.
Answer
The return code 156 on the EZY1293E indicates:
156 EMVSINITIAL All Process initialization error.
The errno 156 might indicate that the OMVS parameters MAXPROCUSER or MAXPROCSYS has been reached. To determine which of these has been reached, you can enter the following Display commands:
D OMVS,A=xxx where xxx is the CICS region ASID. This will show you what PID CICS is running under. D OMVS,O will show you the PID for the failing user.
D OMVS,LIMITS,PID=pidnumber where pidnumber is the PID CICS is running under. This will show the current settings and the high water usage for MAXPROCUSER.
D OMVS,LIMITS This will show the current settings and the high water usage for MAXPROCSYS.
If you see that the value is reaching the high water mark, adjust the value to allow more processes.
In this case, the value in MAXPROCUSER was too low and needed to be increased.
