2.4.1 Creating a new database link
The basic database link configuration requires four pieces of information:
• Suffix information
A suffix is created in the directory tree that is managed by the database link, not a regular
database. This suffix corresponds to the suffix on the remote server that contains the data.
• Bind credentials
When the database link binds to a remote server, it impersonates a user, and this specifies
the DN and the credentials for each database link to use to bind with remote servers.
• LDAP URL
This supplies the LDAP URL of the remote server to which the database link connects.
• List of failover servers
This supplies a list of alternative servers for the database link to contact in the event of a
failure. This configuration item is optional.
2.4.1.1 Creating a new database link using the console
1. In the Directory Server Console, select the Configuration tab.
2. Create a new suffix as described in “Creating suffixes”
Deselect the Create associated database automatically checkbox. It is simpler to configure
a database link on a suffix without a database associated with it because having both a
database and database link requires custom distribution functions to distribute directory
data.
3. In the left pane, right-click the new suffix, and select New Database Link from the pop-up
menu.
