Accessing the Collect Report Data (CRD) panels

You can use the ISPF Online Monitor and its CRD panels to configure a collect task and to start and stop a collect task.

About this task

Before you can access the CRD panels to configure a collect task, the ISPF Online Monitor must be invoked from the IBM Tivoli OMEGAMON XE for DB2 Performance Expert on z/OS main menu. Choose option 3 (View online DB2 activity - PE ISPF OLM) to invoke the ISPF Online Monitor, if not already active.

From the Online Monitor Main Menu, select option 6 (Collect Report Data) or 6a (Collect Report Data - General). Alternatively, enter COLLECT on the command line, or press F17 (Collect).

You can access the collect report data panels from within the Online Monitor by selecting option 6 (Collect Report Data) from the Online Monitor Main Menu.

The Collect Report Data panel is displayed:

   1=Configure
   2=Start
   3=Display
   4=Stop

   Task Description                               Status

From the Collect Report Data panel you can configure and control the collection of report data.

  • Option 1 (Configure) displays a window where you configure collect tasks to collect report data and where you can limit the collection of Db2 trace data to time periods or events of interest. Refer to Configuring a collect task for more details.
  • Option 2 (Start) displays a window where you start a collect task after it has been configured. Starting a collect task actually starts a Db2 trace and enables the start and stop criteria that were specified with option 1 (Configure). Refer to Starting and stopping traces for more details.
  • Option 3 (Display) displays a window that shows the status of a collect task and any messages issued by that collect task. Refer to Displaying trace status and messages for more details.
  • Option 4 (Stop) displays a window where you can stop a collect task and associated Db2 traces. Stopping a collect task prevents the triggering of Db2 traces and stops all traces that were previously started by the task. Refer to Starting and stopping traces for more details.

The Task Description column shows the description of each collect task. You can change a description by overtyping it with another description. The Status field shows the current status of the task.

If you see a task error in the Status field, use the DB2 DISPLAY TRACE command to check if the traces are still running. If necessary, use the DB2 STOP TRACE command to stop the trace. Before you restart the appropriate Collect Report Data function, exit the Collect Report Data panel (by pressing F3) and, in a second step, exit the Online Monitor Main Menu (by pressing F3 again) to return to the IBM Tivoli OMEGAMON XE for DB2 Performance Expert on z/OS main menu. This way you stop the four asynchronous tasks that were automatically set up when you first selected option 3 (View online DB2 activity - PE ISPF OLM) from the IBM OMEGAMON for DB2 Performance Expert on z/OS main menu.
