Operating Environment 
Scalable operation   
 
In scalable operation with Oracle9i RAC, Oracle is operated on all nodes.    Regardless of which 
node a client is connected to, the client is able to use the database. 
 
Standby operation 
 
In standby operation, a cluster system consists of an operational node and standby nodes.    On 
the operational node, Oracle applications, a logical IP address and shared disks are active.    On 
the standby nodes, these resources are inactive.    In the event of a failure, business operation is 
switched to one of the standby nodes, and the resources in this standby node are activated.   
Then, the client can be connected to the running node using the logical IP address without 
modifying any settings.
