What is Output Post Processor?
Concurrent Processing now uses the Output Post Processor (OPP) to enforce post-processing actions for concurrent requests.Post-processing actions are actions taken on concurrent request output. An example of a post-processing action is that used in Concurrent Processing support of XML Publisher.
If a request is submitted with an XML Publisher template specified as a layout for the concurrent request output, then after the concurrent manager finishes running the concurrent program, it will contact the OPP to apply the XML Publisher template and create the final output.
OPP runs as a service that can be managed through Oracle Applications Manager (OAM) from the System Activity page (Navigation: Applications Dashboard > Applications
Service (from the dropdown list) > Go).
The integration of XML Publisher within Concurrent Processing is done by means of a specialized concurrent manager called the Output Post Processor (OPP). If a request is submitted which has an XML Publisher template specified as a layout for the output, then after the concurrent manager finishes running the concurrent program, it will contact the OPP to apply the XML Publisher template and create the final output.
An overview of the actions involved:
1. An application user submits an XML Publisher based report.
2. The standard concurrent manager processes the request.
3. The XML data file is generated by the standard concurrent manager. This can be done by various methods:
o Oracle Reports - Report Definition File (RDF)
o XML Publisher Data Template - XML data template linked to the Data Definition
o Any other process that produces XML output
4. A post processing action defines that the output needs to be generated by the Output Post Processor hence it is triggered by the standard manager.
5. The Output Post Processor generates the final report and informs the standard concurrent manager whether that was successful.
6. The standard concurrent manager finalizes the concurrent request.
Processes in OPP:
There should always be at least one OPP process active in the system. If no OPP service is available to process concurrent requests, completed requests that require OPP post-processing will complete with a status of Warning.
One service instance of the OPP service is seeded by default. This seeded OPP service instance has one workshift with one process.
A concurrent manager contacts an available OPP process when a running concurrent request needs an OPP post-processing action. Concurrent managers use a local OPP process (on the same node) by default, but will choose a remote OPP if no local OPP process is available.
How to Increase the number of Output Post Processors?
1.Log on to Applications with “System Administrator” responsibility.
2.Navigate to Concurrent -> Manager -> Define.
3.Query for the “Output Post Processor” service.
4.Click on “Work Shifts” and increase the number of processes
How to get OPP manager log file location?
$APPLCSF/log/<SID>/FNDOPP####.txt OR
1,System Administrator > Concurrent > Manager > Administer
2,Search for ‘Output Post Processor’
3,Click the ‘Processes’ button .
4,Click the Manager Log button. This will open the ‘OPP’
Upload the OPP log file.
In some cases, Output Post Processor is not start up and it shows Actual and Target are showing different values when we query for Output Post Processor.
The log files shows that no error message.In this case apply the following possible solution for starting the OPP.
1. Shutdown the internal manager by using adcmctl.sh stop apps/apps
2. Make sure there is no FNDLIBR processe running:
$ ps -ef| grep FNDLIBR OR ps -ef|grep applprod|grep FNDLIBR
3. If there is any FNDLIBR processe please kill it $ kill -9 pid
4. Run cmclean.sql script as document from Note 134007.1
5. Restart the internal manager by using adcmctl.sh start apps/apps
