3.1 Verify the Oracle Real Application Clusters Guard Installation

After you have installed Oracle Real Application Clusters Guard software on all nodes in the cluster, you can optionally verify the installation.

This section describes how to perform the tasks involved in installation verification.

3.1.1 Start Oracle Real Application Clusters Guard Manager

After the installation, you can invoke Oracle Real Application Clusters Guard Manager from the Start menu by choosing:

Programs -> Oracle - <Oracle_Home> -> Oracle Real Application Clusters Guard Manager

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

3.1.2 Connect to the Cluster

Oracle Real Application Clusters Guard displays the Connect to Cluster dialog box that allows you to make a connection to a cluster. Figure 3-1 shows an example of a connection.

Figure 3-1 Connect to Cluster Window

Cluster Alias is required input; User Name, Password, and Domain are optional on Windows NT and required on Windows 2000.

Note: If you do not specify a user name, password, or domain, Oracle Real Application Clusters Guard attempts to connect to the cluster using the account with which you logged on to the server node.

The following list describes the input to this 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.

Click OK or press Enter to connect to the cluster.

Once invoked, the Oracle Real Application Clusters Guard Manager main window appears, as shown in Figure 3-2.

3.1.3 Run Verify Cluster

The first time you connect to a cluster after you install Oracle Real Application Clusters Guard, Oracle Real Application Clusters Guard 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 3-3.

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

Figure 3-3 Verify Cluster Operation Results

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.

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 3-4.

   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 3-5.

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 3-6.
