Address Space Bottlenecks Summary workspace

This workspace provides address space-level wait state (bottleneck) information, showing contention percentages by resource. Various types of wait states are identified, including CPU wait percent, I/O wait percent, and enqueue wait percent. (For the full list of address space wait states, see the Address Space Bottleneck attributes.)

To use this workspace effectively, review the Address Space Bottlenecks Summary - Contention (%) by Resource table view to determine whether any address space is exceeding the wait threshold you have specified. This can easily be seen by locating the cells of this table that show either red or yellow alerts to indicate Critical or Warning conditions. For any such address spaces, click the link to drill down to the Address Space Bottlenecks Detail workspace workspace and review the lower-level data presented there. From this view, you can also link to the OMEGAMON for MVS - Job Details workspace for the job in the selected row.

This workspace also contains the Selected Execution States bar chart. The bar chart provides data for address spaces whose jobs have been in one or more of five execution states for at least 5% of time.

The five execution states are:
