Providing an LDAP URL
On the server containing your database link, you have to identify the remote server
that the database link connects with using an LDAP URL. Unlike the standard
LDAP URL format, the URL of the remote server does not specify a suffix. It takes
the following form:
ldap://hostname:portnumber
You specify the URL of the remote server using the
the
cn=database_link_name,cn=chaining database,cn=plugins,cn=config
of the configuration file. For example, the
follows:
nsFarmServerURL: ldap://example.com:389/
Do not forget to use the trailing slash (/) at the end of the URL.
If you want the database link to connect to the remote server using LDAP over SSL,
the LDAP URL of the remote server takes the following form:
ldaps://hostname:portnumber
For more information about chaining and SSL, refer to "Chaining Using SSL," on
page 120.
Providing a List of Failover Servers
You can include additional LDAP URLs for servers to use in the case of failure. To
do so, add alternate servers to the
For example, you might enter the following:
nsFarmServerURL: ldap://example.com us.example.com:389
africa.example.com:1000/
In this sample LDAP URL, the database link first contacts the server
on the standard port to service an operation. If it does not respond, the database
link then contacts the server
then contacts
africa.example.com
