Issue/Introduction

Scheduler fails to complete startup. The process hung after logging the below messages in the event_demon log. Does not proceed to complete the startup process after.
event_demon log($AUTOUSER/out/event_demon.$AUTOSERV) -
CAUAJM_I_40275 Log Rollover level set to <MIDNIGHT,SIZE(100),PURGE(365)>.
CAUAJM_I_40249 Debug level set to <LIGHT,HEAVY,DBQUERY,GBE>.
CAUAJM_I_40378 One Automation Event Management messaging interface initialized successfully
CAUAJM_I_40244 EnableIPCaching value set to <1>.
CAUAJM_I_40244 AggregateStatistics value set to <1>.
CAUAJM_I_10654 System is running in dual server mode. Event server 1: AUTODBPRI. Event server 2: AUTODBSHD.
CAUAJM_W_00173 System appears to have a running primary scheduler. Checking for primary activity.
CAUAJM_W_00176 The primary is not active. Startup proceeding.
CAUAJM_W_40330 The shadow is not active. Startup proceeding.
----
The process does not respond or stop using graceful shutdown (unisrvcntr stop waae_sched.$AUTOSERV). The below snippet is the pstack extract of the scheduler process after issuing the stop command -

Environment

Release : 12.0, 12.01

Component : CA Workload Automation AE (AutoSys)

Cause

The pstack extract (Thread 2) confirms that Autosys does not receive the response from One Automation Event management after the integration initialization.

Resolution

Autosys requires One Automation Event management to be up and running after the integration.

By design, In the environments where Autosys is integrated with One Automation Event management for event alerts, the connection is validated by sending an API request as part of the scheduler startup procedure. The process waits for it to return before initiating the job processing. In this case, The Automic One Event management has a problem in returning the API request due to which the Autosys scheduler process is hung.

To resolve the problem, Ensure the One Automation Event management is up and running fine. Send a test API and see if it returns successfully.

Contact One Automation experts to get the problem resolved.

To work around the problem disable the One Automation Event Management integration with Autosys -

Login to the Autosys server

Kill the scheduler process which was hung

Take a backup of the Autosys configuration file ($AUTOUSER/config.$AUTOSERV)

Update and set the value of the property: OneAutomationEvents to "0"

OneAutomationEvents=0

Save the file and restart the scheduler.
