Using the Cluster Manager

The Cluster Manager allows you to monitor, analyze, and manage the operations of a cluster. It provides status, cache, and session information about the servers and controllers that make up a cluster. It is available only when the Administration Tool is connected to a clustered DSN.

NOTE:  If all Cluster Controllers or Oracle BI Servers in the cluster are currently stopped or offline, you cannot access the Cluster Manager to start them. You must manually start one Cluster Controller (generally, the primary) and one Oracle BI Server.

The Cluster Manager Graphical User Interface (GUI) has two panes: the Explorer pane on the left side and the Information pane on the right side. The Explorer pane displays hierarchical information about the servers, schedulers, and controllers that make up a cluster. The Information pane shows detailed information about an item selected in the Explorer pane.

The Cluster Manager window refreshes every minute by default. You can change the interval.

To set the refresh interval for the display

1. In the Administration Tool, open a repository in online mode.
2. Select Manage > Clusters.
3. To change this value, select Refresh > Every and choose another value from the list.
4. To refresh the display at any time, make sure the Cluster Manager is the active window and press F5, or select Refresh > Now.

   This retrieves the most current information for the cluster.

To activate an inactive Scheduler instance

1. In the Administration Tool, open a repository in online mode.
2. Select Manage > Clusters.
3. In the Cluster Manager dialog box, right-click a Scheduler instance.
4. If the Scheduler instance selected is inactive, select Activate.

   This allows the administrator to dictate the active Scheduler instance at run time.
