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

This lecture covers the configuration and management of dispatcher processes in Oracle databases. It explains how to modify dispatcher attributes, the procedure for shutting down dispatcher processes, and the importance of using the index attribute. The lecture also discusses the assignment of port numbers for security, differences between shared and dedicated server configurations, and key parameters affecting database operations. Additionally, it provides guidance on configuring client connections and using data dictionary views to verify configurations.

What is the recommended practice when modifying dispatcher configurations to avoid mistakes?

• Change all configurations simultaneously

• Modify the first matching configuration

• Always use the index attribute

• Use the default settings

What happens when the 'immediate' keyword is used in the shutdown command for a dispatcher?

• The dispatcher continues to accept new connections

• The dispatcher waits for all users to disconnect

• The dispatcher shuts down after a delay

• The dispatcher stops accepting new connections immediately

Which command is used to view the port number assigned to a dispatcher?

• PORT VIEW

• LSNRCTL SERVICE

• DISPATCHER INFO

• SHOW PORT

In a shared server configuration, what is required for a client to connect to the database?

• A network connection via the listener

• Direct database access

• A local connection without a listener

• A dedicated server process

What does the Max SHARED SERVERS parameter specify?

• The number of dispatcher processes

• The exact number of shared server processes

• The maximum number of shared server processes allowed

• The minimum number of shared server processes

How can a client be configured to always use a dedicated server process?

• Use a shared server configuration

• Do not specify any server type

• Set server to dedicated in the connect descriptor

• Set server to shared in the connect descriptor

What is the role of data dictionary views in shared server configurations?

• To shut down dispatcher processes

• To verify and tune shared server processes

• To modify dispatcher configurations

• To assign port numbers to dispatchers
