Issue/Introduction

During the installation of an AutoSys Agent on UNIX/Linux, the following error occurs:

[CAUAJM_W_116414] Unable to install or upgrade the "WA_AGENT" agent. The agent
installer return code is "255".

From the installation log file:

Custom Action:            cybermation.iainstaller.library.CybFatalLinuxService
                          Status: FATAL ERROR
                          Additional Notes: FATAL ERROR -     class cybermation.iainstaller.library.CybFatalLinuxService FatalInstallException: Service could not be registered. A service with the same Agent name 'WA_AGENT' already exists.  The agent cannot be registered to start automatically at system startup.  Disable the automatic startup or change the Agent name to be unique.

Environment

Release : 12.0

Component : CA Workload Automation AE (AutoSys)

Cause

This error can occur when the Agent directory has been deleted or moved manually, but the Agent startup script still exist in '/etc/init.d' and the softlinks in /etc/rc.d/rc*.d are also still present:

ls -l /etc/init.d/waae_agent*

lrwxrwxrwx. 1 root root 29 Sep 15  2020 K89waae_agent-WA_AGENT -> ../init.d/waae_agent-WA_AGENT

Resolution

The startup script from '/etc/init.d' and the softlinks in '/etc/rc.d/rc*.d' can be manually deleted.

Once done, the installer will not detect an existing WA_AGENT service anymore and will install the Agent and created new files in /etc/
