Using Performance Monitor

Last update March 6, 2019

The CA IDMS Performance Monitor is a performance and tuning tool. The topics in this section describe the following information:

Key Benefits and Features

You can use Performance Monitor to monitor hardware and software resource utilization in a DC/UCF system.


Performance Monitor includes the following components:



Statistics Collected

Realtime Monitor DCAs, DBAs, operators, system programmers Specific system-resource statistics at the time of the request
Interval Monitor DCAs, DBAs System-wide, wait-time statistics for a unit of time (for example, five minutes), which are necessary to track bottlenecks in resource utilization
Application Monitor Application programmers, DCAs, DBAs Statistics about resource usage by individual programs and chargeback/billing information by group code

All three Performance Monitor components are implemented through windowing. Windowing provides the following.

  • Comprehensive online help. You can request help at any time by using the HELP command. The position of the cursor at the time of the request indicates the required level of information. Online help explains the meaning of each Performance Monitor field.
  • The ability to control more data than can fit on the terminal screen. For example, you can scroll to the right to see additional columns of data.
  • Flexible screen displays. You can edit and sort screens to display data in a more meaningful format.

For more information about windowing, see Windowing.

Beginning a Performance Monitor Session

To begin a Performance Monitor session, enter the task code for the monitor you want to use:

Monitor Task Code
Realtime Monitor pmrm
Interval Monitor pmim
Application Monitor pmam

Information on the Screen

The first three lines on your terminal screen define the product, release, date, time of day, window number for the current window (see Windowing) and refresh interval (if installed with the refresh option). This area also provides a field for entering commands and a message area.

The rest of the terminal screen contains one or more windows. Each window displays a monitor screen. The default window is the window that is displayed in the upper-left corner of the terminal screen. Performance Monitor displays as many windows at a time as possible. Use the windowing facility to manipulate the window displays, as described under Windowing.

Note: If secured external monitoring is enabled, only authorized users/groups are allowed to monitor security external systems selected by the Active System Summary function (PF19).

Ending a Session

When you are ready to exit Performance Monitor:

  1. Type quit, bye, or end following the CMD--> prompt
  2. Press [Enter] to return to the ENTER NEXT TASK CODE prompt.
    Note: You can also press [Clear] to exit Performance Monitor.
