You must set up the failover cluster using Microsoft SQL Server Installation Wizard. The explanation here assumes an example that uses Microsoft SQL Server 2000.

When installing Microsoft SQL Server on the local disk of the executing server that comprises the cluster, set up the items listed below. Failover cluster setup is executed.

• Specify a logical host name for the virtual server name, and select Virtual Server.
• For the IP address of the virtual server, specify the logical IP address.
• Set data files on a shared disk.
• For the user name, specify the administrator account that is valid for all servers.
• For the authentication mode, select Mixed Mode (Windows authentication and SQL Server authentication).

When Microsoft SQL Server is installed on the executing server, it is automatically installed and set up on a standby server. For details about how to install and set up Microsoft SQL Server, see the Microsoft SQL Server documentation.

When you use Microsoft SQL Server in a cluster system environment, Hitachi recommends that you use TCP/IP for communication between Microsoft SQL Server and Microsoft SQL Server client.

Set up both the executing and standby servers comprising the cluster by installing the Embedded RDB of Asset Information Manager on the local disks of these servers. During installation, use the same settings for both the executing and standby servers.

You must also change PDHOST of the ODBC data source, which is created automatically during database creation, to the logical host name. The ODBC data source name is the service name of the database information that was set in the Server Setup dialog box.

Install the Oracle server component software and Oracle Fail Safe Server on the local disks of both the executing server and the standby server that constitute the cluster. After that, set up the clustering service using Oracle Fail Safe Manager. Create Oracle database instances on the shared disk. For details about the Oracle cluster environment setup method, see Oracle's Fail Safe documentation.
