Enclave Information Workspace

An enclave is a transaction that spans more than one dispatchable unit of work and more than one address space, and even multiple systems, but is reported on and managed as a single unit of work.

This workspace can be reached from the Navigation view, from the Address Space CPU workspaces, or from the WLM Service Class Resources workspace. When accessed from the Navigator, the Enclave Information workspace provides performance data for all existing enclaves.When accessed by the link from the Address Space CPU Utilization workspace, only the enclaves associated with the address space selected in the link are presented. When accessed from the service class view, only the enclaves in that service class and period are shown.

This workspace contains two views. The Enclave Information table view provides information about the owner, characteristics, and CPU utilization of each enclave. The Enclave CPU % by Address Space bar chart summarizes enclave CPU utilization at the address space level. In the chart, there are two bars for each address space: one for dependent enclaves and one for independent enclaves.

Note: The Enclave Information table view and the Enclave CPU % by Address Space bar chart derive information from different attribute groups. The Enclave Information table view provides data derived from the Enclave Table attributes, while the bar chart provides data derived from the Address Space CPU Utilization attributes. Since the data is not gathered in one atomic operation, there may be discrepancies in the information provided by the table view and bar chart. For example, if an enclave has just completed, it is possible that its owner will be represented in the bar chart even though the enclave does not appear in the Enclave Information table view. When you display this workspace as the result of navigating from another workspace, the Enclave Information table view generally displays only a subset of all of the enclaves in the system. However, the bar chart always reflects all address spaces owning enclaves.

From the Enclave Information workspace, you can navigate to

This workspace can record history.
