Task summary
You can access the complete range of task analysis features through the Tasks menu.
Several task options display summary information on tasks that fit a selected category, for example, waiting tasks or tasks exceeding MAXR. Some of the task options provide detailed information on a single task that fits the selected category, for example, the currently running task. In addition, the Tasks menu includes options to terminate unwanted tasks, to view short and long term transaction rates that exceed a specified threshold, a summary of tasks performing I/O, a summary of tasks using the open transaction environment, a summary of storage usage for each task, a summary of any task with associated data, to view CICS system tasks and non CICS system tasks.
To start the task analysis select the Tasks option (T) on the Main Menu, or enter fast path T. from any screen. The initial display as shown in the following figure summarizes all tasks in the system.

=============================================================================== This screen and any other summary tasks screen on the Tasks menu show the transaction ID, task number, status, facility type, wait resource type, wait resource name, and CPU time used for the tasks that fit the selected category.
By analyzing the wait resource type and name you can determine what state each task is in and what might be delaying further task execution. For more information on wait reasons, press PF1 for Help from the All Tasks screen.
