Getting Started

3.1.1 Start Oracle Fail Safe Manager

After the installation completes, invoke Oracle Fail Safe Manager from the Start menu by choosing:

Programs -> Oracle - <Oracle_Home> -> Oracle Fail Safe Manager

In the example, replace <Oracle_Home> with the name of the Oracle home where you installed Oracle Real Application Clusters Guard.

When Oracle Fail Safe Manager opens, usually the Add Cluster to Tree dialog box is also opened, as shown in Figure 3-1. (If the Add Cluster to Tree dialog box is not open, then from the File menu, choose Add Cluster to Tree.) In the Cluster Alias box, enter the alias for the cluster and then click OK.

After you click OK in the Add Cluster to Tree dialog box, the cluster alias is added to the tree view, and the General tab for the cluster is displayed, as shown in Figure 3-2. However, because Oracle Fail Safe Manager is not yet connected to the cluster, the general tab displays the message: "Oracle Fail Safe Manager is not currently connected to this cluster. To connect, open the File menu, and select Connect to Cluster." The next section describes connecting to a cluster in detail.

3.1.2 Connect to the Cluster

After you add the cluster to the tree view, you must connect to the cluster. Open the Connect to Cluster dialog box by doing one of the following:

• On the File menu, click Connect to Cluster.

• Right-click the cluster alias, then click Connect.

• Click the box to the left of the cluster alias (to expand the cluster alias folder).

Oracle Fail Safe Manager displays the Connect to Cluster dialog box that allows you to make a connection to a cluster, as shown in Figure 3-3. (Note that if both Oracle Fail Safe and Oracle Real Application Clusters Guard are installed on the cluster, Oracle Services for MSCS will open a window that asks whether you want Oracle Fail Safe Manager to present the Oracle Fail Safe or Oracle Real Application Clusters Guard view of the cluster. If you have both products installed, click Real Application Clusters Guard mode.)

The User Name, Password, and Domain are optional on Windows NT and required on Windows 2000 and Windows XP.

The following list describes the input to the Connect to Cluster dialog box:

• User Name

  Enter a user name for a domain account name that has Administrator privileges on all nodes of the cluster where you are connecting.

• Password

  Enter the password for account specified in the User Name field.

• Cluster Alias

  Enter or select the alias name that was assigned when you created the cluster with MSCS. A cluster alias is sometimes referred to as a cluster name.

• Domain

  Enter the name of the domain to which the user name belongs.

• Save as local preferred credentials

  Select to have Oracle Fail Safe Manager save the account information you have entered to a text file, <Oracle_Home>\fs\fsmgr\FsClusters.txt on the system from which you are running Oracle Fail Safe Manager. The password is saved in an encrypted format. This allows you to disconnect and reconnect to the cluster (from your current system) without having to respecify the account information each time a reconnection is requested.

Click OK or press Enter to connect to the cluster.

Once you are connected to the cluster, the Oracle Fail Safe Manager main window appears with the phrase "Real Application Clusters Guard" included in the title bar, as shown in Figure 3-4. Oracle Fail Safe Manager is said to be running in Real Application Clusters Guard mode. For the sake of brevity, Oracle Fail Safe manager running in Real Application Clusters Guard mode is sometimes referred to as Oracle Real Application Clusters Guard Manager or just the manager.

3.1.3 Run Verify Cluster

The first time you connect to a cluster after you install Oracle Real Application Clusters Guard, the manager prompts you to run the Verify Cluster operation to validate the Oracle Real Application Clusters Guard installation and the network configuration. The Verify Cluster operation displays its progress in a Clusterwide Operation window, as shown in Figure 3-5.

(Later, you can run the Verify Cluster operation at any time by choosing Troubleshooting -> Verify Cluster from the manager menu bar. This is especially useful if you later change your cluster configuration.)

Description of the illustration cwo_vc.gif

Verify Cluster performs operations to verify that:

• The Oracle homes are identical on all nodes

• The Oracle Real Application Clusters Guard release is identical on all nodes

• The resource providers are configured identically on all nodes

• The resource providers are disabled if the required software has not been installed

• The Host Name/IP Address mappings resolve consistently across all nodes in the cluster

Verify Cluster also registers with MSCS the Oracle resource DLLs for the resource types supported by Oracle Real Application Clusters Guard.

The Oracle Real Application Clusters Guard Concepts and Administration Guide describes the Verify Cluster operation in more detail.

3.1.4 Verify the OracleMSCSServices Service Entry

Upon successful installation and verification of Oracle Services for MSCS, the Services Control Panel on each cluster node should include a new service entry named OracleMSCSServices.

To verify the OracleMSCSServices entry in the Services Control Panel:

1. Start the Control Panel:

   Start -> Settings -> Control Panel

2. Double-click the Services icon on the Control Panel.

3. Scroll down to the Oracle service listings and locate the OracleMSCSServices entry, as shown in Figure 3-6.

   The Startup status for OracleMSCSServices is displayed as Started on the node where the Cluster Group resides, and it is displayed as Manual on the other cluster nodes.

4. Click Close to exit the Services Control Panel.

5. Perform steps 1 through 4 on each cluster node.

3.1.5 Verify That Oracle Services for MSCS Is in the Cluster Group

The Oracle Services for MSCS service is maintained by MSCS. Upon successful installation of Oracle Services for MSCS on each cluster node, invoke MSCS Cluster Administrator and verify that it includes Oracle Services for MSCS as a resource in the Cluster Group (the group containing the MSCS resources critical to cluster operation).

To verify that Oracle Services for MSCS is listed as a resource, start the MSCS Cluster Administrator, as follows:

Start -> Programs -> Administrative Tools -> Cluster Administrator

Click Cluster Group in the Cluster Administrator tree view to select it, and, in the right-hand pane, locate the Oracle Services for MSCS entry in the Name column, as shown in Figure 3-7.

3.1.6 Verify That Additional Components Were Installed

Upon successful installation of Oracle Real Application Clusters Guard on all cluster nodes, invoke the MSCS Cluster Administrator and verify that it includes the cluster resource types for Oracle Real Application Clusters and the Oracle TNS Listener, as follows.

Start -> Programs -> Administrative Tools -> Cluster Administrator

Select Resource Types in the Cluster Administrator tree view, and, in the right-hand pane, locate the Oracle Real Application Clusters Instance and Oracle TNS Listener entries in the Display Name column, as shown in Figure 3-8.
