Enterprise Manager Ops Center can manage and monitor Oracle Solaris Clusters and their nodes. Enterprise Manager Ops Center manages Oracle Solaris Clusters in the same way as other assets. Cluster assets are of the following types:

You can monitor, provision, and update the software on a cluster's nodes.

After the Oracle Solaris Clusters have been discovered, the Asset tree represents the cluster architecture. A cluster can contain the following components:

Terms Used in Oracle Solaris Clusters

Zone node A non-global zone hosted on a cluster node and is in the nodelist of a resource group. It is active in the resource group but it is not a full cluster node.

Nodelist Specifies the nodes of any type that the resource group can run on.

global cluster A cluster of Oracle Solaris 10 nodes and the host of multiple zone clusters.

resource group A collection of resources and policies that act as a data service

Public interconnect Network connections for data services, always uses IPMP

Private interconnect Network connections for cluster management and configuration

Dual Partition upgrade Upgrades one half of the cluster's nodes, then the other half, so that data service is not interrupted.

CMAS The cluster software's agent. Enterprise Manager Ops Center uses this agent to discover and manage cluster nodes.

Viewing Cluster Details

When you select an Oracle Solaris Cluster, the dashboard shows its components. To see the attributes of a cluster, hover the cursor to see ID, version, and package status. In addition, the status of its quorum service is displayed: device, version, possible votes, and current votes.

When you select the specific cluster, the dashboard shows its components, for example, global nodes and zone clusters. The icons for each type display a number, which indicates the number of nodes or the number of zones.

When you select the Global Node type, the dashboard shows each global node. To see the attributes of a global node, hover the cursor to see OS version, host name, IP address, current votes, and possible votes.

The Alerts tab displays the current alert status for the cluster. The Serial Console tab gives access to the cluster's systems.
