You may not be able to immediately connect to the Dimensions CM database due to lack of network access. In these situations, you can edit your files in your local workspace by changing them to local mode and then checking in the files when you have access to the Dimensions CM repository.
A second method of placing files into local mode is to choose the Work Offline option when you are prompted to connect to the Dimensions CM server.
This enables the Work offline option for your editing session. Working offline automatically changes files to local mode when you attempt to edit them. The work offline session ends either:
when you explicitly connect to an offline connection. This allows you to check in your changes without exiting the IDE.
when you exit your Eclipse workbench. The next time that you start your Eclipse workbench, you will be able to log in to Dimensions CM and check in your changes.
