The COVC transaction provides access to the Web User Interface run-time environment. It can be used to format and manipulate the internal data structures of the Web User Interface.
To run the COVC transaction, log onto the Web User Interface server and enter the COVC transaction ID, together with one of the following debugging commands:
This starts the Web User Interface server if not already started during PLTPI processing.
This shuts down the Web User Interface server.
This displays the COVC trace flags panel, as shown in Figure 11, giving you the opportunity to set appropriate trace levels.
This displays the Web User Interface control blocks using the CODB memory display (for information about the CODB transaction see the CICSPlex SM Problem Determination). You can display a control block directly by specifying the control block on the COVC DUMP command, for example 'COVC DUMP ANCHOR' displays the global anchor block. The control blocks that you can display are listed in Table 7.
