Transient task not being started by SSM after IPL

Products

• OPS/MVS Event Management & Automation

Issue/Introduction

• After IPL, transient tasks managed by System State Manager (SSM) do not start automatically.
  
  
• OPSS started task starts but no dependent tasks are triggered.
  
  
• OPSS must be stopped/started to trigger start up of dependent tasks.

 

Environment

OPS/MVS 14.0

z/OS 3.1

 

Cause

• OPSS is set to PASSIVE MODE in STCTBL.
  
  
• The SSMBEGUX exit filters out resources in PASSIVE mode when setting the DESIRED_STATE during IPL.
  
  
• Because the desired state for OPSS is never set, dependent tasks remain in a DOWN state as their prerequisites are not met.

 

 

 

Resolution

There are two options:

1. Set MODE='ACTIVE' for OPSS in STCTBL.
   |
   or
   
   
2. Update SSMBEGUX to remove the MODE<>'PASSIVE' filter.
