Issue/Introduction

After installation of an z/OS Aagent version 12 following the standard procedure, the agent does not come up because the starting of the STC aborts.

Cause

The problem is with IBM's recommended DIAG trap set (IGVINITCPOOL) and not having defaultjob class defined in the .ini file, the Automic z/OS AGENT attempts to allocate an extended console.
It is this piece of code where the abend happens and needs to be resolved.

Environment

z/OS Agents version 12.2 and 12.3

Resolution

The workaround consists of forcing the defaultjobclass in the Agent configuration.

Enter the following definition 'defaultJobClass =B 'in the WLM section.of the Agents configuration file.

Now the STC will start up and the agent will get operational and will connect to the AE.


Solution:

Update to a fix version listed below or a newer version if available.


Fix version:
