Tip of the week:
Environment: Oracle EBS 12.1.3, Oracle Database 11gR2, RedHat Linux5
Symptoms:
Users unable to open the out files.
Concurrent requests failed with “Post-processing of request failed error message”
One or more post-processing actions failed. Consult the OPP service log for details.
No further attempts will be made to post-process this request.
Cause:
The concurrent manager process was able to successfully invoke the Output Post-Processor (OPP) but encountered a timeout as the OPP takes longer than the value assigned to complete the job.
Solution:
Increase the value of profile Concurrent: OPP Response Timeout . Bounce Apache and retest.
If the issue still exists, perform the following steps.
Increase the number of Output Post Processors as follows:
Increase the number of processes for Output Post Processor.
Additionally, ensure there is a setting of oracle.apps.fnd.cp.opp.OPPServiceThread:2:0:max_threads=5 under Parameters.

Sunthar, EBS shows my Output Post Processor down, when I try to restart via OAM, and look at the Log I receive an “Error occurred while fetching file”. Where would the log file be located and/or what env variable should I be looking at ?

Please run the below query to get the logfile
SELECT fcpp.concurrent_request_id req_id, fcp.node_name, fcp.logfile_name
FROM fnd_conc_pp_actions fcpp, fnd_concurrent_processes fcp
WHERE fcpp.processor_id = fcp.concurrent_process_id
AND fcpp.action_type = 6
AND fcpp.concurrent_request_id = yourrequestid
Thanks….
