Issue/Introduction

Our team is been trying to upgrade the agents from 12.x (7314) to version newer like 24.0.

When user upgrade a UNIX base agents it just says successfully upgraded on Action/Upgrade status details but it remains on same version and build as before.  Message from the upgrade log in spool/de_agent_cmd

Environment

Workload Automation Agent: 12.x or above

Workload Automation DE (ESP dSeries): 12.4 or above

OS: Linux

Cause

The /tmp folder in Linux does not have exec permission.

 

 

Resolution

Change the permission of /tmp with following command root / sudo

mount -o remount,exec /tmp

Then run the upgrade of Linux agent from Agent inventory.   Once done, revert the permission with this command:

mount -o remount,noexec /tmp

Note: Create job in the DE / manager that can run the above command as root instead of running it manually.  In the job, select the agent that needs to be upgraded.  Create a second job that revert the permissions back to noexec.
