Core group collection Use this page to view the core groups that are defined
for your
system. A core group is a component of the high availability manager
function.
A default core group, called DefaultCoreGroup, is created for each
cell in
the product environment. A core group can contain stand-alone servers,
cluster
members, node agents and the deployment manager. A core group must
contain
at least one node agent or the deployment manager.
Core group policies Use this page to create or update the various high availability
group policies. For a given high availability group, the associated
policy determines which members of the group should be made active.
Core group policy settings Use this page to define a policy for a high availability
group. A policy is defined at the core group level. It only applies
to matching high availability groups contained within this core group
Core group server move options Use this page to move one or more core group servers to
a different core group. You must stop a core group server before you
move it.
Core group server settings Use this page to view the servers that are part of a core
group
and to define or edit custom properties for a core group server.
Core group servers collection Use this page to view a list of the servers that are part of a
core group. A core group server can be an application server, a deployment
manager, or a node agent that is a member of a high availability core group.
Use this page to move servers into a different core group. All members of
a cluster must be in the same core group. If you select one or more members
of a cluster, all of the members of that cluster must be moved.
Core group service settings Use this page to set up the application server properties
that relate to core groups.
Core group settings Use this page to create a core group or to edit an existing
core group. A core group is a component of the high availability manager
function. It can contain stand-alone servers, cluster members, node
agents, administrative agents, and the deployment manager.
Discovery and failure detection settings Use this page to configure the discovery and failure detection
settings for a core group. These settings are used to monitor the
health of core group members. The discovery protocol establishes network
connectivity between core group members of the core group. The failure
detection protocol monitors the established network connections. Both
the default discovery protocol and the default failure protocol run
at regularly scheduled intervals on all started core group members.
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.
Preferred coordinator servers settings Use this page to define an ordered list of preferred core
group servers. This list indicates where the high availability manager
coordinators will run.
Preferred servers Use this page to define the ordered list of preferred
servers for the selected policy. The policy gives preference to
the servers in this list when activating group members.
Servers with active members collection Use this page to determine how many high availability group
members are active on a particular application server.
Static group servers collection Use this page to designate for a static policy which high
availability
group members should be made active.
