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.

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:

Environment

Release : 12.0

Component : CA Workload Automation AE (AutoSys)

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/
