You can configure directory server failover for IBM®
Tivoli® Directory Server by specifying a list
of host:port pairs, by using multiple IP addresses, or by configuring
virtual IP failover.
About this task
For a complete description of directory server failover
options, see Failover Support (IBM
Tivoli Directory Server).
Procedure
To configure directory server failover:
- Access the domain directory configuration properties in
the administration console:
- In the domain navigation pane, click the domain (the
top-level object).
- Click the Directory Configuration tab.
- Click the directory configuration that you want to modify.
- In the directory configuration Properties tab,
select one of the following options and modify the Directory
Server Host field as follows:
Option |
Description |
Specify a failover list. |
Enter a list of host:port pairs in the Host property.
Separate the host name and port number pairs with a space character.
Each pair must consist of a host name and port number, as follows: Hostname1:Port1 Hostname2:Port2 Hostname3:Port3 ... HostnameN:PortN
The
following failover configuration example uses host:port pairs:- Host
- tds1:389 tds2:389 tds3:389 (for nonsecured
connection)
- tds1:636 tds2:636 tds3:636 (for SSL connection)
- Port
- Content Platform Engine ignores
any value in this property.
- Global catalog host
- gc4:3268 gc5:3268 gc6:3268 (for nonsecured
connection)
- gc4:3269 gc5:3269 gc6:3269 (for SSL connection)
- Global catalog port
- Content Platform Engine ignores
any value in this property.

Configure failover by specifying a DNS A record that represents
multiple IP addresses. |
- Create a DNS A record for each Tivoli Directory Server that you want to use
for failover in your local site. For each DNS A record, the name must
be the same but the Tivoli Directory Server IP
address must be different. For failover to work, you must have at
least two Tivoli Directory Server servers.
- Enter the name for the DNS A record in the Host and Global
catalog host fields.
The following example shows how
to configure failover by using multiple IP addresses. The example
is based on the following assumptions:
In the administration console, you can set the following
fields for this example: - Host
- localTDS
- Port
- 389
For more information about DNS A records, see your DNS Server
documentation.
|
Specify a virtual IP. |
Enter the domain information for your environment.- Host
- The virtual IP address or host name
- Port
- Your port number, such as 389.
Failover configuration example that uses a domain
name
- Host
- 10.10.10.11 (a virtual IP address)
- Port
- 389
