Distributed Relational Database Architecture › CA 2E Implementation of DRDA › Shipped Defaults

Shipped Defaults

In keeping with CA 2E's implementation independent design capabilities, you do not have to modify the design of a function to use DRDA. To generate a DRDA application from an existing design, you set generation options and regenerate the functions, but the design remains the same.

CA 2E ships the default values for the new model values, file options, and function options. You explicitly set DRDA functionality. If you do not specify distributed processing functionality for your model, DRDA functionality does not affect it.

By setting certain flags, you can choose how you wish to generate and implement your distributed applications. The shipped defaults for the options that drive CA 2E distributed function creation are:

• New model values:
  • YGENRDB (*NONE - no DRDA compilation enabled)
  • YDSTFIO (*NONE - no generation of distributed functionality)
• Distributed flag: Distributed - N (No); flag for each CA 2E file in the model
• Function option: Distributed File I/O control - M (MDLVAL); YDSTFIO model value

Use of these defaults is described later in this chapter.
