Determining System Resources

System resources may be difficult to determine at the planning stage. Once you define the hardware and software requirements of the application, such as the database system or file system you want to use or any extra security features you may want to have, then you can determine:
  • How much virtual storage you need to set up your application system.
  • How much storage space your application requires.
  • How much processor time your application requires. If your application requires a large amount of processor time, you may want to run it in a batch environment or send it to a disconnected virtual machine to run. This frees your terminal for other work.
See the appropriate books describing the resource requirements needed for each licensed program or feature. Begin by looking in the planning material, administration material, or both for each licensed program.
