The changelog backend supports a db-directory property that specifies the absolute or relative path (relative to the local server root) to the file system directory that is used to hold the Oracle Berkeley DB Java Edition database files containing the data for this backend.

If you change the changelog database location, you must stop and restart the Directory Server for the change to take effect. If the changelog backend is already enabled, then the database files must be manually moved or copied to the new location while the server is stopped.
