How Linkages are Created

Command routing paths, or linkages, enable you to issue cross-system commands and to receive the cross-system responses to those commands. When you create a linkage, you authorize a command source on the local system to issue commands to a target system. CA MIC uses a console you designate on the target system to execute commands issued through a linkage. The designated console is known as the target console for the linkage.

The LINK command lets you create, modify, and delete linkages that enable consoles, products, internal and instream command sources, and TSO users on the local system to issue commands to any system. Each linkage you create by using the LINK ADD command is referenced by the command source you specify. The following are examples of linkage command sources:

CONSOLE=TAPECON1
PRODUCT=RCS
TSOUSER=DSIAZ11

After a linkage is defined, you can modify or delete the linkage by specifying the same command source named on subsequent LINK commands. You also use the command source to delete a linkage. Except for exclusive linkages, there cannot be two linkages with the same command source.

When you specify the SOURCE operand, the command source for the linkage is the source from which the LINK command is being issued.

Note: For more information about the LINK command, see the Statement and Command Reference Guide.
