Oracle® Fail Safe Installation Guide
Release 3.3.1 for Windows
Part No. A96685-01
This chapter contains the following topics to help you connect to a cluster and get started using Oracle Fail Safe Manager:
|Starting the Manager and Verifying the Oracle Fail Safe Installation||Section 3.1|
|Oracle Fail Safe Manager Tutorial and Online Help||Section 3.2|
This section describes how to start Oracle Fail Safe Manager, connect to the cluster, and perform the tasks involved in installation verification.
After the installation completes, invoke Oracle Fail Safe Manager from the Windows taskbar by choosing:
-> Oracle - <Oracle_Home>
-> Oracle Fail Safe Manager
In the example, replace <Oracle_Home> with the name of the Oracle home where you installed Oracle Fail Safe.
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, from the File menu, choose Add Cluster to Tree.) In the Cluster Alias box, enter the alias for the cluster and then click OK.
Figure 3-1 Adding a Cluster to the Tree View
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.
Figure 3-2 Oracle Fail Safe Manager with Cluster Added to Tree View
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 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 Fail Safe mode.)
Figure 3-3 Connect to Cluster Dialog Box
Cluster Alias is required input; User Name, Password, and Domain are optional on Windows NT and required on Windows 2000. The Save as Local Preferred Credentials option is not a required choice on either Windows system.
Note:If you do not specify a user name, password, or domain, Oracle Fail Safe 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 the Connect to Cluster dialog box:
Enter a user name for a domain account name that has Administrator privileges on all nodes of the cluster where you are connecting.
Enter the password for account specified in the User Name field.
Contains the alias of the cluster that you selected from the tree view. The alias name is assigned to the cluster when you (or someone else) created the cluster with MSCS. A cluster alias is sometimes referred to as a cluster name.
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 expands the tree view, as shown in Figure 3-4.
Figure 3-4 Oracle Fail Safe Manager
The first time you connect to a cluster after you install Oracle Fail Safe, Oracle Fail Safe Manager prompts you to run the Verify Cluster operation to validate the Oracle Fail Safe installation and the network configuration. The Verify Cluster operation displays its progress in a Verifying Cluster 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 Oracle Fail Safe Manager menu bar. This is especially useful if you later change your cluster configuration.)
Figure 3-5 Verify Cluster Operation Results
Verify Cluster performs operations to verify that:
The Oracle homes are identical on all nodes
The Oracle Fail Safe 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 resource DLLs for the resource types that Oracle Fail Safe supports.
The Oracle Fail Safe Concepts and Administration Guide describes the Verify Cluster operation in more detail.
Start the Control Panel:
> Control Panel
Open the Services Window:
On Windows NT, double-click the Services icon on the Control Panel.
On Windows 2000, double-click Administrative Tools, then Services on the Control Panel.
Scroll down to the Oracle service listings and locate the OracleMSCSServices entry, as shown for Windows NT in Figure 3-6.
Click Close to exit the Services Control Panel.
Perform steps 1 through 4 on each cluster node.
Figure 3-6 Services Dialog Box on Windows NT
The Oracle Services for MSCS service is maintained by MSCS. Upon successful installation of the Oracle Services for MSCS on each cluster node, invoke the 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).
-> 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.
Figure 3-7 Oracle Services for MSCS in the Cluster Administrator Window
After installing Oracle Services for MSCS on all cluster nodes and verifying the cluster, invoke the MSCS Cluster Administrator and verify that it includes the cluster resource types for Oracle Fail Safe.
For example, if you have the Oracle database server installed on your cluster nodes, start the MSCS Cluster Administrator, as follows:
-> Administrative Tools
-> Cluster Administrator
Select Resource Types in the Cluster Administrator tree view, and, in the right-hand pane, locate the Oracle Database and Oracle TNS Listener entries in the Display Name column, as shown in Figure 3-8.

For detailed step-by-step instructions about using Oracle Fail Safe Manager, refer to the Oracle Fail Safe tutorial and help. To access these online tools, from the Oracle Fail Safe Manager menu bar, choose Help
-> Contents or Help
-> Tutorial for step-by-step instructions, as shown in Figure 3-9.
Figure 3-9 Help Menu
The online help is your primary source of information when you use Oracle Fail Safe Manager. For example, if you select Contents in the Help menu, the Help window displays the first help topic. If you select Search for Help on, a Help window opens to display Contents, Index, and Find tabs (similar to what you find in Microsoft Windows Help). You can find common tasks under the Contents tab and in the Index. The Find tab allows you to perform a full text search of the Oracle Fail Safe Manager Help.
The help contains topics for both Oracle Fail Safe users and Oracle Real Application Clusters Guard users. The following conventions are used to differentiate among topics specific to one or the other software program:
Topics that are specific to Oracle Fail Safe contain the phrase "Fail Safe mode" in the help topic title.
Topics that are specific to Oracle Real Application Clusters Guard contain the phrase "Real Application Clusters Guard mode" in the help topic title.
Topics that apply to both software programs have no reference to Fail Safe or Real Application Clusters Guard in the help topic title.
To view the full set of Oracle Fail Safe documentation, select Online Manuals.
In addition, first-time users might want to browse through the online quick tour, which provides an easy-to-follow overview of Windows clusters and the ways you can deploy highly available business solutions with Oracle Fail Safe. You can access the quick tour from the Windows taskbar after you have installed Oracle Fail Safe. Choose: Start
-> Oracle - <Oracle_Home>
