The commands are used to display entries in the coupling facility trace table (CFTT) and manage the CFs in a processor configuration. The following lists the CF commands and their functions:
See TPF Operations for more information about these commands.
This section shows a scenario of how you might use the CF commands to manage CFs in a processor configuration by providing examples that span a series of commands.
Example 1: In the following example, two CFs are added to a processor configuration. First, a CF named CFONE, which is attached to symbolic device address (SDA) 1001, is added. Then, a CF named CFTWO, which is attached to SDA 510, is added.
A third CF named CFTHREE is enabled (normal operations are resumed on a CF that had been disabled) after a previous error interrupted it and the error has since been corrected. A TPF system tries to enable a fourth CF named CFFOUR after a previous error interrupted it and the error has not been corrected.

Example 2: In the following example, the fourth CF named CFFOUR is deleted from a processor configuration. By mistake, an attempt is made to delete the first CF named CFONE after a function started running on it.
+--------------------------------------------------------------------------------+ |User: ZMCFT DELETE CFFOUR | |System: MCFT0002I 07.59.28 CFMDEL - COUPLING FACILITY CFFOUR DELETED | | | |User: ZMCFT DELETE CFONE | |System: MCFT0011T 07:57.24 CFMDEL - COUPLING FACILITY CFONE NOT DELETED - THERE| | ARE STILL STRUCTURES ALLOCATED | +--------------------------------------------------------------------------------+
Example 3: In the following example, you tried to add the first CF named CFONE to a processor configuration again. You also tried to add a fifth CF named CFFIVE to a processor configuration, but the SDA you specified is already being used by another CF.
