The CA IDMS Delays panel enables you to pinpoint bottlenecks due to CA IDMS requests.
On this panel, you can easily see the percentage of CA IDMS samples taken during the monitored period where CA Mainframe Application Tuner detected tasks in CA IDMS. CA Mainframe Application Tuner is reporting whether or not each task is executing or waiting at the time the samples were taken.
You can use one of the following methods to access this panel:

The previous panel shows CA IDMS delays summarized by Module and Offset, sorted by Totl% (default).
See the following panel for an example of these delays summarized by TaskCode.
A description for each field in the CA IDMS Delays panel follows.
Name of the profile that you specified when you created the monitor definition.
Type of analysis in effect: NORMAL, ALL, ACTIVE, or WAIT.
An asterisk (*) following the value indicates that tasks or transactions have been selected for analysis. Place the cursor on the Options field value and press Enter to display a pop-up panel listing the selected tasks/transactions.
Unique name that identifies a task to CA IDMS DC/UCF.
The user types the task code in response to the DC/UCF system prompt. Task codes are defined at system generation or by using a DCMT VARY DYNAMIC TASK command.
Name of the program requesting CA IDMS DB/DC services, when known, or the name of the program invoked by specifying the task code.
Relative address within the module to which control will be returned upon completion of the CA IDMS DB/DC service request.
Status of the CA IDMS DB/DC service request, whether it is waiting for resources, ready to execute, or executing.
Percentage of CA IDMS samples taken during the monitored period where CA Mainframe Application Tuner detected CA IDMS TASKs either executing or waiting for resources.
Visual depiction of the Totl% value.
Identifier of the ECB on which the task is waiting.
The ECB can be internal as defined by CA IDMS macro #ECBDS or external as defined by CA IDMS macro #ELEDS.
Note: Scroll right to see this field on the CA IDMS Delays panel.

To see the CA IDMS Wait reasons, select the CA IDMS Delay panel by choosing option 15 from the Interactive Analysis Menu. You might need to scroll to the right (depending on your screen size and terminal model) to see the Wait field. This field displays the identifier of the ECB on which the task is waiting.
