Using Fusion Middleware Control to Configure Primary and Secondary Instances

6-8 System Administrators Guide for Oracle Business Intelligence Enterprise Edition The instance score is an internal score that the load balancing algorithm associates with each Presentation Services instance in the cluster. It is based on various metrics that are collected by the load balancer. Set this parameter to true to disallow request redirection, or false to allow requests to be redirected. For example: oracle.bi.presentation.sawconnect.loadbalance.AlwaysKeepSessionAffiliation=true 3. Save and close the file.

4. Restart the analytics application from the Oracle WebLogic Server Administration

Console. If Oracle BI Publisher is using the Oracle BI Presentation Catalog, then the xmlpserver application must also be restarted.

5. Repeat these steps for each computer that hosts the analytics Java component.

6.4 Using the Cluster Manager

The Cluster Manager in the Administration Tool was used in previous releases to monitor and manage Oracle BI Server, Oracle BI Scheduler, and Cluster Controller instances. This tool is still supported in the current release. Although you use Fusion Middleware Control for most administrative tasks that relate to clustered components, the Cluster Manager provides a useful way to view and change the state of clustered components. For example, you can view the currently active Oracle BI Scheduler instance and change the active instance to a different Oracle BI Scheduler if necessary. You can also see which Oracle BI Server is the Master BI Server. Fusion Middleware Control shows the current status of clustered components, but does not provide a way to view or change the current state. The Cluster Manager lets you monitor, analyze, and manage the operations of Oracle BI Server, Oracle BI Scheduler, and Cluster Controller instances in a cluster. It provides status, cache, and session information. The Cluster Manager is available only when the Administration Tool is connected to a clustered DSN. If all Cluster Controllers or Oracle BI Servers in the cluster are currently stopped or offline, then 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 window 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 comprise 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, then Clusters.

3. Select Refresh, then Every, and select another value from the list.

4. To refresh the display at any time, ensure that the Cluster Manager is the active window and press F5, or select Refresh, then Now. This action retrieves the most current information for the cluster. To activate an inactive Oracle BI Scheduler instance: Deploying Oracle Business Intelligence for High Availability 6-9 1. In the Administration Tool, open a repository in online mode.

2. Select Manage, then Clusters.

3. In the Cluster Manager dialog, right-click an Oracle BI Scheduler instance.

4. If the Oracle BI Scheduler instance selected is inactive, then select Activate.

6.4.1 Viewing and Managing Cluster Information

The section describes how to view status, cache, and session information about a cluster and the meaning of the information provided.

6.4.1.1 Status Information

The Status view is automatically displayed when you first open the Cluster Manager window. You can also access the Status view by selecting View, then Status in the Cluster Manager window. The categories of information that are displayed in the Information pane might vary depending on the server to which the Administration Tool is connected. Table 6–4 describes categories that might appear. Table 6–4 Status Columns Column Description Last Reported Time The time that the Cluster Controller or Oracle BI Server communicated with the Controlling Cluster Controller. If the server or controller is offline, then this field might be blank. Name The name of the computer that is hosting the Oracle BI Server or Cluster Controller. Role The role of the object in the cluster: ■ Controlling. A Cluster Controller that is currently assigned the responsibility for control of the cluster. ■ Primary. The Primary Cluster Controller. This role is not displayed if the Primary Cluster Controller is currently the controlling Cluster Controller. ■ Secondary. The Secondary Cluster Controller. This role is not displayed if the Secondary Cluster Controller is currently the controlling Cluster Controller. ■ Clustered server. An Oracle BI Server that is a member of the cluster. This role is not displayed for the clustered server that is defined as the master server. ■ Master. The clustered server that the Administration Tool connects to for editing repositories in online mode. ■ Active. The Oracle BI Scheduler is active. Sessions This field is available when either Servers or an individual server is selected in the Explorer pane. It shows the number of sessions that are currently logged on to a clustered server. Start Time The timestamp showing when the Cluster Controller or Oracle BI Server was last started. This field is blank if the Cluster Controller or clustered server is offline.
