In cases where disk space issues arise, you can change the on-disk location of the LDAP
Change Log database. The changelog backend supports a
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 then 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.
