OCF local functions are subsystem functions providing cross-system communications services for Beta product started tasks, batch jobs, online users, or programs running on the same operating system as the OCF local functions. Depending on the Beta product and the product features, OCF functions can either run exclusively in their own address space, or they can run in the same address space as the Beta product started tasks.
OCF remote functions are subsystem functions providing cross-system communication services for Beta product started tasks, batch jobs, online users, or programs running on an operating system connected via an SNA network to the operating system running the local OCF functions. Again, depending on the Beta product implementation and product features, the OCF remote functions can either be running exclusively in their own address space or they can be running in the same address space as the Beta product started tasks.
During the installation of any Beta product requiring the services of the Open Communication Facility, a set of startup parameters is created. Parameters are tailored to your installation requirements which you specify when running the installation REXX. When you submit the installation jobs, the startup parameter members are placed into the BETA.PARMLIB member assigned to the Beta product concerned.
The OCF startup parameters are used for controlling how VTAM resources are used when local subsystems and batch jobs communicate with remote subsystems. Please refer to the description of the startup deck.
