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. Use the admin console to view the distribution of active high availability group members across the appservers. we need to know the name of the core group that contains the high availability groups you want 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 active high availability group member distribution for the servers in a core group.

• You want to determine whether a particular server is overloaded because it is hosting the active member for multiple high availability groups.

• You want to check the current active member distribution before you update policies that might affect this distribution.

• You want to verify that you obtained the proper results to the current active member distribution after a policy change goes into affect.

To view the distribution of active high availability group members:

 

1. In the admin console ...

   Servers > Core Groups > Core group settings.

2. Click the core group that contains the high availability groups you want 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 that contain the specified name-value pairs in their group name. For example, we might specify the following value to obtain a list of all of the high availability groups that contain IBM_hc=MyCluster and type=WAS_TRANSACTIONS in their names.

     IBM_hc=MyCluster,type=WAS_TRANSACTIONS
     

5. Click Show servers.
