How to start OPP(output post processor)

What is OPP?

Concurrent Processing now uses the Output Post Processor (OPP) to append 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).
