You can find out if whether command flow information is collected about a transaction from any view where a Transaction resource is displayed in the CICS® IA plug-in.
To view the Command Flow of a transaction, right-click the chosen transaction in the transactions tab and select Show Command Flow runs from the menu. You can then either choose to display the command flow runs for all user IDs, the current user ID, or specific user IDs.
The results are displayed in the Show Resources view. The user ID is shown with the region, the time of the first command issued for each user ID, and the Task ID.
You can analyze the Task ID information that is associated with a user ID by, right-clicking a Task ID and select Show Execution option from the menu.
The results, that show the execution of that task, are displayed in the Command Flow view.
The information in the Command Flow view is broken down into three sections, TCB Modes Used, and TCB Mode Switches in the upper section of the view, and the lower section of the view that displays the Command Flow information.
The Command Flows are ordered by time under the Program that ran the command. TCB Mode and previous TCB Mode are shown for each command.
If
a command caused a TCB Mode switch to occur the icon for the command
has a TCB mode switch icon attached to it. If the command has a nonzero RESP or RESP2
code the icon for the command has a warning icon
attached
to it. If you click a command with the warning icon the response codes
and reason codes are displayed in the lower bar of the Command Flow
view in decimal:
If you open the command flow editor for your user ID and change the query but do not save, when you try and start your user ID you are prompted to avoid the data loss. When the editor is closed you are prompted with a warning which allows you to either restore the editor with the unsaved changes or to ignore the failure and not to restore the editor.
You cannot open the command flow editor (view) when the collector is running, the corresponding button is disabled automatically when it starts. If the editor is already open, you can open the IA Operations view and click start, in which case you see a warning telling you that you must stop it first. You can use the editor to change some values, but you cannot save the changes until you stop the collector. The warning message allows you to do so by pressing Yes. Or you can go back to the editor by clicking No.
Column customizing
TCB Modes Used
You can maximize and minimize the command flow tree using the plus and minus icons. The total commands issued is displayed in the upper right of the view.
The TCB Modes Used view displays a summary of the TCB modes that were used during the execution of the task.
Commands and Resources are grouped and displayed by the mode that they operated under. If you select a command the command flow tree highlights the command in the lower section of the Command Flow view.
TCB Mode Switches
The TCB Mode Switches section of the Command Flow view displays a summary of any TCB mode switches that occurred during the running of the task.
Commands and Resources are grouped and displayed by the mode that they switched from and to. If you select a command the command flow tree highlights the command in the lower section of the Command Flow view.
Creating an Event Processing Capture Specification
You can use the Command Flow information to create a capture specification to be used with Event Processing:
Events associated with EXEC CICS commands
Events associated with EXEC CICS commands are displayed as child nodes of the command in the view. These child nodes are the events that are triggered against a command.
