If you have disk space issues, you can change the on-disk location of the LDAP changelog database.
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 PingDirectory 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.
