Managing Cross-System Command Traffic › Defining Types of Linkages

Defining Types of Linkages

Once potential target consoles have been identified on each target system, decide how you want CA MIC to select the target consoles. CA MIC selects a target console on each system to which a cross-system command is issued. Use one of these methods to select consoles:

• Define a shared linkage to tell CA MIC to select a console from a pool of target consoles available on the target system. The consoles in the pool are shared by all external command sources you identify on LINK commands.
• Define a dedicated linkage to tell CA MIC to select a console from a pool of target consoles available on the target system. Once selected, the target console is removed from the pool and dedicated to the external command source.
• Define an exclusive linkage to specify the console name of a specific target console that you want to assign to a command source.

The method you use depends upon factors such as the availability of target consoles and the number of command sources. Use the POOL or TGTCONS parameters on the LINK command to define the type and allocation method to be used with the target console pool. The following sections describe the advantages and disadvantages of each type of linkage and tell you how to create each linkage.

Note: The concept of target consoles is valid only when issuing cross-system commands to a z/OS system running CA MIC for z/OS. When cross-system commands are issued to a z/VM system running CA MIC for z/VM, the commands are executed through the MIMGR service machine.
