WCC services going down

Products

• CA Workload Automation AE - Scheduler (AutoSys)

Issue/Introduction

Our WCC services on UAT hosts are going down unexpected without any clear indication nor crash.

Environment

Release : 11.3.6 and 12.x

Component : 

Cause

From the log files we see that WCC receives a SHUTDOWN command on the shutdown port:

   CA-wcc.log

INFO   | jvm 1    | 2021/09/02 01:57:35 |    22580 | INFO: A valid shutdown command was received via the shutdown port. Stopping the Server instance.

    CA-wcc_services.log

INFO   | jvm 1    | 2021/09/02 01:57:30 |    22576 | INFO: A valid shutdown command was received via the shutdown port. Stopping the Server instance.

Resolution

WCC received a shutdown request thru the shutdown port 8005. 

Disabling the shutdown port using following steps

1. cd $CA_WCC_INSTALL_LOCATION/tomcat/conf
    cp -p server.xml server.xml_original
    vi server.xml

    and search for following line (in my server.xml it is on line 13

<Server port="8005" shutdown="">

    port 8005 is the default port number that has been chosen at installation time. It might be different in your environment.
    Change port "8005" to "-1". 
    This will disable that someone might perform a shutdown of the tomcat using that port number
    However you will be still able to stop/start WCC services using command "unisrvcntr"

2. cd $CA_WCC_INSTALL_LOCATION/tomcat_32/conf

             # for r12 release, there is no such option, so no need to follow this step for 12.x

    cp -p server.xml server.xml_original
    vi server.xml

    and search for following line (in my server.xml it is on line 14

<Server port="10133" shutdown="">

     Change port to "-1".

Stop/start the CA-wcc and CA-wcc-services.
