• One is the name of the catalog file, as you see it from your computer’s desktop. This is called the catalog file name.
• The other is the name of the catalog, as seen in the catalog window’s title bar. This is simply called the catalog name.
When a catalog is first created, the catalog name defaults to the same name as the catalog file. Newly created catalogs are named the same as their file names by default, but the catalog name can be changed at any time.
Before you rename a catalog, be aware that a catalog’s name is an internal reference within Cumulus. The catalog name is the name users will see when connecting to catalogs, and it also appears at the top of catalog windows. It’s important to remember after renaming a catalog, that you must update the permissions of any users (or roles) that have restricted catalog access that includes access to the renamed catalog. This is because restricted catalog access permission is based on the names of catalog, so users will not be able to access renamed catalogs until those newly renamed catalogs are added back into the list of accessible catalogs for that user (or role).
Note that catalogs cannot be renamed while set to use the Cumulus Vault in Always and Exclusive mode.
To change a catalog name (what you see in the catalog window):
1. Make sure the collection window containing the catalog is the active window in Cumulus.
2. Select Cumulus / Edit > Preferences.
3. Click Catalog Settings.
The Catalog Settings window is displayed. If the active collection window contains more than one catalog, select the catalog you want to edit under Catalogs.
4. Click General. You’ll see a field labeled Name.
5. Enter a new name for the catalog in the Name field and click OK. The change is saved and the window closes.
You change a catalog’s file name as you would any other file.
