Oracle's Connection Manager, or CMAN, is a new application that is available with Oracle8 Enterprise Edition.
CMAN is very similar to the Net8 listener, and provides support for connection concentration, network access control, and multi-protocol support.
One of the shortcomings of the Net8 listener is that it will accept connections from any Oracle client that knows the required information
(port number of the listener, host address, and database name). With CMAN you can specify which remote databases are allowed to make listener
After completing this module, you will be able to:
Describe the features of the Connection Manager
Configure the Connection Manager
Start and stop the Connection Manager
Use SQL*Net with connections to multiple protocols
In the next lesson, you will examine the function of CMANs three server programs.
