Job resubmission fails in some Linux OS with WA Agent

Products

• Workload Automation Agent
• CA Workload Automation AE - System Agent (AutoSys)

Issue/Introduction

When a user resubmits the same job that they receive a permission denied response in the spool file. 

Environment

Release : Any

Component : Workload Automation System Agent

OS: Linux / Ubuntu / RHEL

Cause

In newer Linux distros (post 2023), the OS may not allow a user that does not own the file to make changes to it, including root.  This permission is enforced when "fs.protected_regular" kernel parameter is set to 1.

Resolution

Set the fs.protected_regular kernel parameter to 0.  See this KD for more details on setting the parameters.

Alternatively, run all the jobs as same user as that starts the agent (e.g. root).
