Networks have evolved from simple terminal-based systems to complex multitiered systems. Today's networks can comprise many computers on multiple operating systems using a wide variety of protocols and communicating across wide geographic areas. We need look no further than the explosion of the Internet to see how networking has matured and what a profound impact networks have on the way we work and communicate.
Although networks have become increasingly complex, they also have become easier to use and manage. For instance, we all take advantage of the Internet without knowing or caring about the components that make this communication possible because the complexity of this huge network is completely hidden from us.
The experienced Oracle database administrator has seen this maturation process in the Oracle network architecture as well. From the first version of SQL*Net to the latest releases of Oracle Net, Oracle has evolved its network strategy and infrastructure to meet the demands of the rapidly changing landscape of network communications.
This chapter highlights the areas that you need to consider when implementing an Oracle network strategy and the responsibilities that you have when managing an Oracle Database 10g (Oracle 10g) network. We'll also discuss the most common network configurations. The chapter introduces the features of Oracle Net—the connectivity management software that is the backbone of the Oracle network architecture. We'll explain how to configure the main client and server-side components of Oracle Net, and we'll discuss the tools that you have at your disposal to perform these tasks.
