Screen Description

The Active User Task Detail screen displays a line of information for each user task in the dispatch chain. The tasks are sorted by task dispatching priority, from lowest to highest. This screen helps you determine why the system is slow.

If you have the appropriate DCMT discrete security, you can use this screen:

• to change the dispatching priority for a task
• to terminate an active task on the local system

This screen can also be used to terminate an active task executing on a remote Central Version (z/OS only). Canceling tasks running on a remote Central Version is controlled by your external security system. For more information, see the chapter Installation and Customization in the CA IDMS Performance Monitor System Administration Guide.

To do so, type over the existing value in the appropriate column for the task and press ENTER:

Important! You cannot change the task priority for a system that is being monitored remotely.

What To Look For

• Look for a task that is in a wait status (Task Status is WAIT) for a long time. If you know that the resource for which the task is waiting will not be available in the appropriate amount of time, you can terminate the task as described above.

  Event control blocks (ECBs) define what a task is waiting on. For example, an ECB of LMGR indicates that the task is waiting on a lock that is managed by the database lock manager. For more information about ECBs, see the CA ADS DSECT Reference Guide.

• When storage protection is on, look for a number in the Priv Aloc field that is much higher than the sum of the Priv Below and Priv XA fields. This indicates that the task is allocating more storage than it is actually using. In a CA ADS application, this situation can result from incorrect sizing of the record buffer blocks (RBBs). In a non CA ADS environment, examine the application for poor storage allocation.
