How to: automatically cycle one of a pair of started tasks in some cases

Issue/Introduction

Given a pair of started tasks, if one abnormally terminates we need to recycle the other so that the function works.  Is there a simple way to automatically do that while preserving the normal behavior when we shut down a system?

Resolution

This suggestion requires the implementation of the FCYCLE function of the SSMCNTL rule. Check the comments section of the SSMCNTL rule in the **.CCLXRULM library for the required steps to implement the FCYCLE function.

The solution is to create specific FAILED_UP actions in the action table for the 2 tasks. The delivered FAILED_UP action has the following action text: 

RULE("SSMRSTRT &SSM!RESNAME &SSM#RESTARTS &SSM#RSTCNT")

Here is an example where the tasks are STC1 and STC2. For the first task duplicate the current FAILED_UP entry and set STC1 as ACTION_RES_TYPE and include a new action to recycle STC2. 

The columns should look like: 

 ACTION_RES_TYPE STC1 action_text RULE("SSMRSTRT &SSM!RESNAME &SSM#RESTARTS &SSM#RSTCNT");MVSCMD("SSM FCYCLE JOB=STC2") 

 A similar entry would have to be created for STC2 changing the FCYCLE command to STC1 as the second action.
