Monitoring Record Level Sharing
This topic describes the workspaces that monitor the status of Record Level Sharing. You access these workspaces through the Record Level Sharing Summary node in the Tivoli® Enterprise Portal.
See Workspaces for general information on predefined workspaces and a list of all nodes that are included in the OMEGAMON for Storage on z/OS product. Each node corresponds to a specific area of storage resource monitoring. And each node includes links to a unique set of storage resource workspaces. See Workspaces to learn about navigating among workspaces. Also see Workspaces to learn about linking to the workspaces of other IBM Tivoli Monitoring products.
In addition, with OMEGAMON for Storage on z/OS Version 4.2.0 Interim Feature 3 or later, you can issue dataset-level Storage Toolkit commands from the dataset group level. To access these commands, open the RLS Summary workspace from the Navigator, right-click a row on the table view and select the Dataset Actions... menu item, then select the action you want to perform.
