Oracle BI Publisher - OPP (Output Post Processor)

The Output Post Processor (OPP) is mainly used to process post actions of concurrent requests. For instance once the concurrent manager finishes running the concurrent program, it will communicate with OPP to apply the XML Publisher template and create the final output. The services run by OPP are managed through OAM (Oracle Applications Manager). A minimum of one OPP process should always be available in the system to process the concurrent request, otherwise OPP will complete with status WARNING. Depending on the availability the concurrent manager may contact local or remote OPP while running a concurrent request. The OPP service is a multi threaded and initiates a new thread for every concurrent request it processes. We can also view more details of OPP service in OAM. So depending on your work, one can manage the workshifts and the number of threads per process to handle the workload.
