Hi Kenan Yes there are several documents to determine the hardware and bandwidth. According to Oracle Methods PJM 4.1, there are documents under [TA] Application and Technical Architecture headline see detail given below. TA.110 Define System Capacity Plan document will help you to size the stuff you want. You must have good understanding of existing and future transaction volumes, annual growth, number of users, OS, non oracle tools and applications, deployment architecture, patching and room for upgradation related tasks etc. to calculate the exact sizing. You can find it under ABF 1.4 - AIM for Business Flows and it covers; Production/TEST Environment Servers Server Capacity Requirements Processing Capacity Requirements - Server Class and CPUs Memory Requirements Disk Capacity Requirements Regards Imran Kiani Phase Task Overview Template Core/Opt Definition A TA.010 Define Architecture Requirements and Strategy Architecture Requirements and Strategy Core A TA.020 Identify Current Technical Architecture Current Technical Architecture Baseline Optional A TA.030 Develop Preliminary Conceptual Architecture Preliminary Conceptual Architecture Optional Elaboration B TA.050 Define System Availability Strategy System Availability Strategy Core B TA.060 Define Reporting and Information Access Strategy Reporting and Information Access Strategy Optional B TA.070 Revise Conceptual Architecture No template provided.
