Define an Option Set Control Table

An Option Set Control Table (OSCT) is used to define the optional features that the APPC link supports during communication. The option sets provide these optional features.

To define an OSCT, use the DEFOPSET command. You can specify single or parallel session links by using the PARSESS operand. However, if not specified, the default is parallel sessions.

During the activation of a link, the OSCT entry nominated in the DLT definition for the destination is used to determine the supported options and to indicate the associated mode names.

Example: Define an Option Set Control Table

To define an OPSET of NMOPSET with single session links issue the following command:

DEFOPSET OPSET=NMOPSET PARSESS=NO 

Note: For more information, see the description of the DEFOPSET command in the online help.
