A dispatcher can support multiple client connects concurrently while a shared server process can be dedicated to only one dispatcher.
Under the Oracle Shared Server architecture, client-user processes connect to shared user processes.
Each dispatcher has its own request queue, which is monitored every three seconds by the dispatcher.
Oracle Shared Server required Oracle Net Service even if the client and shared server processes reside on the same machine.
第1题:
What is the new Oracle Shared Server?()
第2题:
What type of configuration can provide the best availability in a Virtual IO Server environment?()
第3题:
The Oracle Shared Server architecture reduces memory usage by reducing the number of server processes required. To process a request for a server process, the following tasks are performed: 1.A shared server picks up the request from the request queue and processes the request. 2.The dispatcher retrieves the response from the response queue. 3.A user sends a request to its dispatcher. 4.The dispatcher returns the response to the user. 5.The shared sever places the response on the calling dispatcher’s response queue. 6.The dispatcher places the request into the request queue in the SGA. Put the above task in the order in which they are performed.()

第20题:
An improved version of multithreaded server configuration.
A connection pooling configuration where several clients are connected to the same server process.
Two more database servers, which share data by means of database links; the client software is unaware to which server it is connected.
A configuration of Real Application Cluster where the client connection is routed to the least busy instance.
第21题:
The initial request from the client to the listener.
Messages between the dispatcher and the shared server background processes.
A redirect message from the listener to the client during client connections.
Round-trip messages between the listener and the shared server background processes.
第22题:
The dispatcher returns the response to the user.
The dispatcher places the request into the request queue.
The shared server places the response in the response queue.
The response is handed off to the next available dispatcher.
A shared server picks up the request from the request queue and processes the request.
第23题:
The listener hands the connection request directly to a dispatcher.
A dedicated server inherits the connection request from the listener.
The client connects to a dedicated server directly using a protocol address provided by the listener.
The application initiating the session spawns a dedicated server process for the connection request.
The listener issues a redirect message to the client, containing the protocol address of a dispatcher. The client then terminates the network session to the listener and establishes a network session to the dispatcher, using the network address provided in the redirect message.
