There are situations where you must select a preferred
IP address, or a range of IP addresses that you want the high availability
manager to use for communication within a core group.
Before you begin
Determine the transport protocol the core group associated
with the high availability manager uses for communications.
About this task
Deprecated feature: Support for unicast
transports is deprecated. If the core group is configured to use unicast
transports, you should change the configuration settings to channel
framework transports wherever it is possible to do so.

You
should only set a preferred IP address if you want to restrict the
high availability manager communications to a specific IP address.
To configure a preferred IP address, complete the following steps:
Procedure
- Make a list of all of the product processes that are on
this machine.
Include both application server processes
and administrative processes, such as node agents or the deployment
manager, in this list. If a preferred IP is set for one process on
a machine, it should be set for all processes on that machine
- Determine the textual form of the preferred IP address. For example, 9.5.87.124 or 10.1.2.2.
- Update the IP address specified for the DCS unicast address
for all processes identified in the first substep with the textual
form of the preferred IP address.
- In the administrative console, navigate to the settings
page for either an application server, a node agent, or a deployment
manager.
For an application server process click .
For a node agent process click .
For a deployment manager process click .
- Select the appropriate process.
- In the Additional Properties section, , click to bring up the list of
ports for the selected process. Then click on the port named .
- Enter the preferred IP address in the Host field.
Following are the allowed values for the Host field:
- * (asterisk), which allows high availability manager communications
on all NICs. This is the default value, but cannot be used if your
processes must interact with V6.0 or V6.0.1 processes.
- Text IP address, such as 10.1.1.2, which restricts high availability
manager communications to the specified NIC. Text IP addresses can
be used if the host is configured to use a single IP address.
- A string host name of the form myhost.mydomain.
- Click , and then click to save your changes.
What to do next
The high availability manager uses the specified IP address
for communication within the core group.
