Connectivity and Networking
One of the DBA’ key tasks is to establish and maintain connectivity between the database on the server and the user community. In the traditional client/server model, users connect to databases on separate servers by using a client, and the client/server model is still used in many places to run business functions. However, web-based connection models are much more common today as a means of connecting to databases. Oracle calls its set of connectivity solutions (which encompasses connectivity, manageability, and network security) Oracle Net (previously SQL Net) Services. In this chapter, I show how to use Oracle Net, a component of Oracle Net Services, to make and maintain connections between clients and databases. I also show you how to install the Oracle Client software. You’ll also see how to use the new Oracle Instant Client, which lets you connect to an Oracle database without the use of network configuration files.
