The core group bridge service can be configured to establish
communication between core groups. A core group is a statically defined
component of the high availability manager. To configure communication
between core groups, use an access point group. An access point group
is a collection of core groups that communicate with each other.
Before you begin
Before you configure a core group bridge service, become familiar
with the content of the following topics:
- Core groups, which describes the functionality of
a core group.
- Creating a new core group (high availability domain),
which describes how to configure a core group.
- Configuring communication between core groups that are in
the same cell, which describes how to configure communication
between core groups that are in the same cell.
- Creating advanced core group bridge configurations,
which describes how to configure two or more core groups, such that
the members of each core group can communicate with the members of
the other core groups, even if one or more of the other core groups
resides outside of a firewall.
About this task
You must configure the core group bridge service whenever
two or more core groups are configured in the same cell. You must
also configure the core group bridge if you need to share traffic
among core groups that are in different cells. Configure the core
group bridge to communicate between cells only when the service is
required by another product component. By configuring the core group
bridge service, the availability status of the servers in each core
group is shared among all the configured core groups. You can configure
core groups to communicate in the following ways:
Procedure
- Configure the core group bridge service for communication
between two core groups that are in the same cell. You
can configure each core group to communicate with one or more of the
other core groups in the cell.
- Configure the core group bridge service for communication
between two core groups that are in different cells. You can configure the core group in one cell to communicate
with a core group in the other cell.
- Configure the core group bridge service for communication
within the cell, and outside of the cell.
- Configure the core group bridge service for communication
using a tunnel peer access point. This is the type of communication
that you must configure if you are using a DMZ Secure Proxy Server for IBM® WebSphere® Application Server.
Results
Multiple core groups can communicate with each other.
What to do next
Continue configuring the high availability environment.
