You can improve the performance of the CICS® PA plug-in by closing projects that are not in use.
Closed projects require less memory. When a project is closed, you cannot change it in the CICS Explorer® workbench and its resources do not appear in the workbench, but the project still exists on the local file system.
When a project is open, its resources are displayed in the workbench and you can change it in the workbench.
For further information about creating projects and other Eclipse functions, see Eclipse Workbench User Guide.
