Issue:

The OSF uses OPSOSF address spaces as servers that handle asynchronous action requests from various CA OPS/MVS facilities.

OPSOSF address spaces have the following characteristics:

1. They include the following facilities:

– Automated Operations Facility (AOF)

– Enhanced Console Facility (ECF)

– IMS Operations Facility (IOF)

– Multi-system Facility (MSF).

2. They use z/OS cross-memory services to handle action requests.

3. They may be swappable or non-swappable, as determined by the value of OSFSWAPPABLE parameter.

4. They are started and stopped by CA OPS/MVS as necessary, although the number of active servers must fall within the bounds set by the following parameters:

– OSFMIN and OSFMAX

– OSFTSLMIN and OSFTSLMAX

– OSFTSPMIN and OSFTSPMAX

– USSMIN and USSMAX

It can happen that these OPSOSF dynamic tasks abend S013 with the below messages:

What is the cause of this kind of abend and how to prevent it from happening?  

 

Environment:

CA OPSMVS - OPSOSF Component 

 

Cause:

The OPS2023S message and the subsequent S013 ABEND will be issued any time an OPSOSF server attempts to do I/O to SYSTSPRT or SYSTSIN subsystem datasets and OPSMAIN (the central address space for CA OPS/MVS) has not created a control block for that ASID yet. 

This can mostly happen if: 

1) An MVS START OPSOSF command is issued manually. 
2) OPSOSF has a higher WLM class than that of OPSMAIN. 

OPSMAIN issues an ASCRE (address space create request) Z/OS service call.

The return code from the call includes the ASID of the newly created OPSOSF address space. 
If OPSMAIN is suspended by WLM after the ASCRE completes but before OPSMAIN creates the server control block and the OPSOSF server reaches the point of asking for data via the SYSTSIN / SYSTSPRT DD subsys datasets, the OPS2023S message is issued when OPS sees the server request. 

 

Resolution:

 

This is usually a temporary error situation which can be prevented increasing the Z/OS WLM Service Class for OPSMAIN so that it could not be suspended by WLM during the ASCRE/SCB creation for OPSOSF.
