Oracle Database Administration from Zero to Hero - Configuring Databases for Shared Server (Part 2 of 3)

The video tutorial explains the configuration of the dispatchers parameter in Oracle Database. It covers the basics of enabling shared servers, setting up dispatchers for different protocols, and tuning parameters for large systems. The tutorial also details the attributes of dispatchers, such as protocol, address, and description, and provides examples of single and multiple dispatcher configurations. It emphasizes the importance of understanding index attributes for managing multiple configurations and highlights the need for consulting Oracle Reference documentation for full syntax details.

What is the primary role of a dispatcher in Oracle Database?

• To manage user authentication

• To handle incoming connection requests

• To store database backups

• To optimize query performance

Which attribute is mandatory when setting the dispatchers parameter?

• Description

• Any one of Protocol, Address, or Description

• Address

• Protocol

What does the sessions attribute specify in a dispatcher configuration?

• The number of dispatchers to start

• The listener associated with the dispatcher

• The maximum number of network sessions per dispatcher

• The protocol used by the dispatcher

What is the default value for the number of dispatchers when not specified?

• Zero

• One

• Three

• Two

Which attribute would you use to specify a particular listener for a dispatcher?

• Index

• Service

• Protocol

• Listener

In a single dispatcher configuration, what happens if the service name does not match the one registered in the listener?

• The dispatcher will not start

• The dispatcher will use a default service

• The dispatcher will handle all services

• Connection requests will be rejected

How can you configure multiple dispatchers for different protocols?

• By using separate configuration files

• By setting multiple dispatcher parameters

• By using the index attribute

• By restarting the database

What is the purpose of the index attribute in dispatcher configurations?

• To set the maximum connections

• To specify the protocol

• To define the service name

• To differentiate between multiple dispatchers

If you want to add a new dispatcher configuration without affecting existing ones, which attribute would you use?

• Protocol

• Index

• Service

• Address

What happens if a dispatcher configuration with a specific index already exists and you set a new configuration with the same index?

• Both configurations run simultaneously

• The new configuration is ignored

• The existing configuration is overridden

• The existing configuration is removed
