Oracle recommends that you compare your OPPM configuration to the parameters described in Appendix A. OPPM performance may vary depending upon the type of operations, data fields/parameters etc.
For the purposes of these guidelines, implementation "size" is measured by the peak number of simultaneous OPPM users. The peak number of simultaneous users is a good indicator of how your hardware should be configured; however, there are many factors that may yield unpredictable results. These factors include: the size of the database, the types of operations a given set of users performs, and other factors determined by the characteristics of the solution implemented in OPPM. For a complete list of these factors, see Appendix A.
OPPM is a highly customizable platform. Performance and hardware requirements heavily depend on the data configuration and the nature and number of calculations. OPPM hardware guidelines give you an idea of what different sizes of configurations look like, but actual needs vary depending upon the details of the implementation and customer requirements. Oracle recommends that you assess hardware needs for OPPM components after the design of the OPPM implementation is complete.
