Steps to Fix Output Post Processor Startup in EBS R12

 Steps to Fix Output Post Processor Startup

In Oracle E-Business Suite, there are occasions when we encounter issues such as the Output Post Processor failing to start up, resulting in a mismatch between the actual number of processes and the target number of processes. Consequently, many concurrent programs end up completing with errors or warnings.

Solution: To resolve such issues, follow these steps:

1. Restart the manager called "Output Post Processor" from the frontend:

   • Log in to Oracle Applications with sysadmin responsibility.
   • Navigate to: Concurrent -> Managers -> Administer.
   • Select "Output Post Processor" and click on the "Restart" button.

2. If the above step does not resolve the issue, perform a complete application stack restart:

   • Ensure no processes are running from the application end after shutting down services.
   • Execute the "ps ux" command from the OS application user to check for any running processes.
   • If any processes are found, terminate them using the "kill -9 process_id" command.

Once completed, restart the application. This should resolve the issue with the Output Post Processor.
