Issue/Introduction

Hi

We're trying to uninstall an agent and install it again but are facing issues.

Below is details of the commands run and folder structure, after the uninstall we could see some folders still existing and after the fresh install could still see the old version of the agent

We've also noticed the agent is stating uninstall v6.6, but this doesn't match with the version ?

bash-4.2$ ./uninstall

Environment

Release : 6.6

Component : CA Release Automation Core

Cause

The below is not an error but a message, as the only user has access to remove a service from run-level is either root or the one belonging to root group.

Failed to remove agent startup script from runlevels. Needs to be removed manually.

New install shows old version

During cause analysis it was observed that for some irregularities there are more than one directory with same name on Linux OS which doesn't look right. A new installation in the same directory is referencing to old incorrect conf/version file

Resolution

Failed to remove agent startup script from runlevels. Needs to be removed manually.

Resolution: Login as root and remove the agent service from run-level

New install shows old version

Resolution: Run the command changing the directory where the agent is getting installed

bash-4.2$ ./nolio_agent_linux_x64_6_6_0_b9640.sh -q -Vsys.installationDir=/opt/CA/CARAAgent -Vnolio.nimi.port=6600 -Vinstall.service.lsa$Boolean=true -Vnolio.nimi.secured$Boolean=true -Vnolio.execution.name=EXECUTION_SERVER_HOST -Vnolio.execution.port=6600 -Vnolio.hiddenport$Boolean=false -Vsys.programGroupDisabled$Boolean=false -Vsys.component.336$Boolean=true -Vsys.programGroupName=Nolio -Vsys.programGroupAllUsers$Boolean=true -Vsys.languageId=en
