View high availability group information

High availability groups are dynamically created components of a core group. They cannot be configured directly, but they are directly affected by static data, such as policy configurations, which is specified at the core group level. We can use the console to view information about the high availability groups that are part of a core group.

You need to know the name of the core group containing the high availability groups to view. You should also determine if we need to view all of the high availability groups or a subset of these groups, based on the group name.

We might want to perform this task if:

• You want to view the current set of high availability groups.

• You want to view the group name of a high availability group.

• You want to view the policy that is associated with a high availability group.

• You want to view the state of a high availability group

To view information about the high availability groups contained in a core group:

1. In the console, click Servers > Core Groups > Core group settings.

2. Click the core group containing the high availability groups to view.

3. Click the Runtime tab.

4. Specify a value in the Group name field.

   • Specify an asterisk in this field if we want a list of all the high availability groups that are part of this core group.

   • Specify a set of name-value pairs, separated by a comma, to get a list of only those high availability groups containing the specified name-value pairs in their group name. For example, you might specify the following value to obtain a list of all of the high availability groups containing IBM_hc=MyCluster and type=WAS_TRANSACTIONS in their names.
     IBM_hc=MyCluster,type=WAS_TRANSACTIONS

5. Click Show groups.

Results

A list of high availability groups contained in this core group that meet the specified criteria is displayed, with pertinent information about these groups.

What to do next

We can click on the name of one of the high availability group names to display information about members of that group. Because high availability group members are dynamically created, no member information is available for configured servers that are not actually running.

We can also view the distribution of active high availability group members.

Subtopics

• View the distribution of active high availability group members
  Because high availability group members are dynamically created, core group policy configuration is used to determine which high availability group members the high availability manager activates. In some situations, it is possible for active members of multiple high availability groups to all be running on the same server process. We can use the console to view the distribution of active high availability group members across the application servers.

• Servers with active members collection
  Use this page to determine how many high availability group members are active on a particular application server.

• High availability groups collection
  Use this page to view information about the high availability groups contained in a core group.

• High availability group members collection
  Use this page to view information about the individual members of a high availability group. This page lists the current members of the selected high availability group.
