You can improve the performance of the CICS® PA plug-in by closing projects that you are not using.
When a project is closed
you can no longer change it in the Workbench and its resources no
longer appear in the Workbench, but it does still exist on the local
file system. Closed projects require less memory. Closed projects
are indicated by the closed project icon next to the project name.
When a project is open
you can make changes to it in the Workbench and its resources exist
on the local file system. Open projects are indicated by the open
project icon next to the project name.
For further information on creating projects and other Eclipse functions, see the Eclipse Workbench User Guide.
