In the illustration below, the file system is on a shared disk, mounted on node 1 only.
The following Symfoware Server resources are located in this file system:
Data storage destination directory
Tablespaces
Backup data storage destination directory
Transaction log storage destination directory
A Symfoware Server process waits for connections of user applications that access the database, on a client access point activated on node 1 only.
*1: A client access point is an IP address given to a cluster service.
A client that connects to a database can connect continually to an active database server by connecting to this IP address.
In Windows Server(R) 2003, this IP address is called a "cluster IP address".
When an error is detected on node 1, Microsoft Failover Clustering / Windows Failover Clustering or Microsoft Cluster Service mounts the file system on node 2 and activates the client access point on node 2. The Symfoware Server process is also started on node 2. Since the client access point remains unchanged, the user application can access Symfoware Server process on node 2 simply by re-establishing the database connection.
