Issue/Introduction

Trying to start the AutoSys services via the unisrvcntr command fails with this output:

(example trying to start the Application Server for an instance named ACE)

$ unisrvcntr start waae_server.ACE
Starting waae_server.ACE (via systemctl):  Job for waae_server.A12.service failed because the control process exited with error code. See "systemctl status waae_server.ACE.service" and "journalctl -xe" for details.
                                                           [FAILED]
Executed waae_server.ACE start...................................FAIL 1

In the system's /var/log/messages log you may see something like:

The issue persists with unisrvcntr despite:

Successfully start the services using the /etc/init.d/waae* startup scripts

Confirming the $AUTOSYS/csutils/bin/assrvc file has root ownership and the setuid bit:

-rwsr-xr-x. 1 root root 123112 Jun  8  2020 assrvc

 

Environment

CA AutoSys Workload Automation 12.x

Cause

This has been known to occur if SELinux is enabled and contains a policy preventing the user switch when the unisrvcntr command executes $AUTOSYS/csutils/bin/assrvc with the setuid bit.

Resolution

Check if SELinux is enabled with command 'sestatus'.

Try disabling it temporarily in the 'etc/selinux/config' file as mentioned in this link:
https://access.redhat.com/solutions/3176

The unisrvcntr command will work, confirming it is an SELinux policy issue.

Consult your system admins about disabling SELinux or removing the blocking policy.
