Screen Description

The Task and Program Pool Overview screen displays summary information about both task and program activity. The screen is divided into two parts:

• Task activity
• Program-pool activity

You can request detailed information about user tasks, system tasks, and program-pool activity, as follows:

• To request the Active User Task Detail screen to view detailed information about the system resources used by active user tasks, type any nonblank character in the select field to the left of Task Activity Summary.
• To request the Active System Task Detail screen to view detailed information about the system resources used by active system tasks, type any nonblank character in the select field to the left of System Task.
• To request the Program Pool Detail screen to view detailed information about program-pool use, type any nonblank character in the select field to the left of Program Pool Summary.

When you have selected the screens you want, press [Enter]. The Realtime Monitor creates a new window for each screen requested.

What To Look For

• Look for a non-zero number in the Wait fields in the Program Pool Summary. A non-zero number indicates programs have to wait for space in the program pool. Investigate this condition further by displaying the Program Pool Detail screen.
• Look for high values in the Aborted task count field. Lower abort numbers are preferable for a production system while higher abort numbers may be okay for a development system.
• Look for Times at Max # values that are close to the Genned Max # value. This indicates that the concurrency level is limited by the MAX TASK value specified in the system generation SYSTEM statement.
