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 administrative console to view the distribution of active high availability group members across the application servers.
We need to know the name of the core group containing the high availability groups we want to view. We 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.
Perform this task...
- To view the current active high availability group member distribution for the servers in a core group.
- To determine whether a particular server is overloaded because it is hosting the active member for multiple high availability groups.
- To check the current active member distribution before you update policies that might affect this distribution.
- To verify that we 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:
Tasks
- In the administrative console, click...
Servers > Core Groups > Core group settings > core_group > Runtime
- 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
- Click Show servers.
A list of servers displays that shows the number of active high availability group members on each server.
