Issue/Introduction

We recently migrated from CA Autosys Workload Automation from 11.3.6 to 12.0.1 and we found some of the jobs thrown the following error when triggered:

T_X11TransTRANS(ibmSHMConnect) () can't connect: errno = 68
Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server us
ing ':0.0' as the value of the DISPLAY variable.

A similar error was not triggered when running with 11.3.6 client and agent. 

Environment

Release : 12.0

Component : CA Workload Automation System Agent

Cause

The jobs in question have their own specific profiles rather than using /etc/auto.profile

Resolution

The best option is to edit /etc/auto.profile and commented out the following
DISPLAY=":0.0"
export DISPLAY

This will not require an agent restart

The second option is to Uncomment the following parameter in the agentparm.txt, restart the System Agent service and re-run the job

oscomponent.profiles.global.override=true

Additional Information

Using the java environment variable

-Djava.awt.headless=true

Will prevent Java from using the UI.
