Press Enter to refresh the panel for the latest information. This panel summarizes several of the most important OMEGAMON for CICS (3270) features: exception, bottleneck, task, and enqueue analysis.

The overview display is divided into four areas and provides information on the following features:

Exception Analysis: OMEGAMON for CICS (3270) automatically tests dozens of conditions against predefined thresholds and reports any potential problems by displaying a warning message with an exception name. For additional information on the exception analysis feature, see Exception analysis.
Bottleneck Analysis: OMEGAMON for CICS (3270) monitors CICS activity and reports on any condition causing CICS to wait. The wait reasons listed here are internal to CICS. Contention caused by other workloads running on this processor are detected by impact analysis and can be accessed by selecting the Impact Analysis (E) of the Bottleneck Analysis panel. For more information on the OMEGAMON for CICS (3270) bottleneck analysis feature, see Bottleneck analysis.
Task Analysis: A list of all tasks in a wait condition displays automatically. The transaction ID and task number are included as well as the name and type of resource causing the wait. For a list of associated wait reasons, select All Tasks (A) on the Tasks menu or enter T. to fast path, and then press PF1 for Help. For more information on OMEGAMON for CICS (3270) task analysis, see Task analysis.
Enqueue Analysis: Any task holding a resource causing another task to wait is detected and displayed by Enqueue Analysis. The task name and number as well as the name of the resource being waited for is listed. For additional information on the enqueue analysis feature, see Exception analysis.

For an explanation of an exception condition and recommendations for resolving it, place the cursor on the exception line and press PF11. To obtain more information about a wait-reason, waiting task, or enqueue resource, move the cursor to the line describing the item and press PF11.
