High availability group settings

Use this page to manage the state of a high availability groups.
To view this administrative console page, click Servers > Core groups > Core group settings > core_group. Click on the Runtime tab. In the Group name properties field, specify a match criterion for a specific high availability group, or specify an asterisk (*) to get a list of all the high availability groups that are part of this core group. (A match criterion is one or more name=value pairs that match attributes contained in a high availability group's name.) Then click Show groups.

High availability group Names of the high availability groups. The name of a high availability group is a set of name=value pairs or attributes, separated with commas. For example, name=productiongroup,policy=abc,ibm=websphere could be the name of a high availability group. This field is read-only.
Quorum Specifies if quorum is enabled for each high availability group. This field is read-only.
Policy Lists the policies that have match criteria that matches properties contained in the name of that high availability group. There should only be one policy listed for a high availability group. However, if multiple policies have match criteria that equally match properties in a high availability group's name, all of the policies with matching criteria are listed, and the ERROR icon appears in the status column.
For example, if you have a high availability group named name=productiongroup,policy=abc,ibm=websphere, and MyPolicy1 has the match criteria name=productiongroup, and MyPolicy2 has the match criteria policy=abc, both MyPolicy1 and MyPolicy2 are considered matching policies and are listed in the Policy column.
This field is read-only.
Status Indicates, with icons, whether or not only one policy is associated with a high availability group. If the OK icon displays in this column, a single policy is associated with that high availability group. If the ERROR icon displays in this column, multiple policies are associated with that group.
If the ERROR icon displays for a high availability group, adjust the match criteria for one or more of the policies listed in the Policy column for that group so that the correct policy is the only one associated with that high availability group.
The match criteria for multiple policies can match some of the same properties in a group's name as long as one policy has a match criteria that matches more of the properties in that group's name than the match criteria of any of the other policies. For example, if you have a high availability group with a name that consists of the following name and value pairs:
name=productiongroup,policy=abc,ibm=websphere

and MyPolicy1 has the match criteria name=productiongroup and MyPolicy2 has the match criteria name=productiongroup,ibm=websphere MyPolicy2 is considered the matching policy because it has more match criteria that matched the properties contained in the high availability group's name.
This field is read-only.

Use the Disable button if you want to prevent all of the members of a high availability group from being activated. One of the few times you might want to use this button is if you are planning to remove or delete the server on which this group is running.
Use the Enable button to enable all of the members of a high availability group that were previously disabled. These members can then be activated according to the policy associated with that group.
