Viewing a command flow timeline

You can view a timeline of the commands that the Command Flow Collector has collected. The commands are grouped by program, then displayed in rows or columns that represent the different platforms and applications, regions, or Task Control Block (TCB) modes that were used.

About this task

To view a command flow timeline for a transaction, you select the required transaction task ID from a command flow run. You can show whether the transaction switches between regions or between TCB modes.

Procedure

  1. Use one of the following procedures to display the required transaction task ID in a command flow run.
    1. In the User Command Flow view, expand the tree structure to display the transaction task ID for the command flow run you require.
    2. From a view that shows the required transaction resource, for example the Transactions view, right-click the required transaction and click Show Command Flow runs.
      Click one of the following options, as required:
      • All user IDs
      • Current User ID
      • Select User IDs. Select the required user IDs from the resulting dialog, then click OK.
      Transaction pop-up menu with Show Command Flow runs option selected
      The command flow runs for the selected transaction are displayed in the Show Resources view, listed by user ID.

      Expand the tree structure in the Show Resources view to show the transaction task ID for the command flow run you require.

  2. Right-click the task ID of the required command flow run, click Visualization, then click one of the following options:
    • Application Switches. Display the programs in rows or columns that represent the program and applications, with arrows to show the switches.
    • Region Switches. Display the programs in rows or columns that represent the regions, with arrows to show the switches.
    • TCB Switches. Display the programs in rows or columns that represent the TCB modes in use, with arrows to show the switches.
    Command flow run and the task pop-up menu with the Visualization > TCB Switches option selected.
