Issue/Introduction

After upgrading Agents MVS from 12.1.x to 12.3.x, the OS/390 Jobs remain in status "Waiting for Resources" and JOB is not submitted to JES2.

For every trial to submit a JOB, this RunID is tried to be re-executed every 10 seconds with U02000005 messages, and nothing is submitted.

20210129/080003.496 - U02000005 Job 'JOBNAME$' with RunID '52226063' started.    
20210129/080013.539 - U02000015 Periodical job test started.                           
20210129/080013.668 - U02000005 Job 'JOBNAME$' with RunID '52226063' started.    
20210129/080023.669 - U02000015 Periodical job test started.                           
20210129/080023.738 - U02000005 Job 'JOBNAME$' with RunID '52226063' started.    

In the Logging(LOG) of the Job in this Status we have the following messages every X seconds:

U00012124 Agent reports remote status ' '
U00012123 Remote resource is available on host

 

Cause

Bug: a function returns in some Partitions in Agents 12.3.x a non-initialized value, which prevents Jobs to start.

Environment

Release : 12.3

Component : AUTOMATION ENGINE

Subcomponent: Agent for z/OS (MVS)

Resolution

Workaround:

Add the following two lines into the ini file of the agent z/OS 12.3.x

(WLM)

InitiatorCheck=SYSTEM

 

Save and restart the Agent, jobs will now be submitted correctly.

 

Solution:

This problem should be fixed in an ulterior Service Pack 12.3.x yet to be planned.
