6 Quick Start to Oracle Net Services

Help novice users set up and test a simple but common network configuration, such as one between a client application and a database over a TCP/IP network.

• Prerequisites for Establishing Connectivity
  The tasks in this chapter show a TCP/IP connection between a database server and a client computer.
• Confirming Network Availability
  Before using Oracle Net to connect a client computer to a database server, confirm that the client computer can successfully communicate with the database server computer. Evaluating network connectivity can eliminate network-based errors.
• Starting Oracle Net Listener and the Oracle Database Server
  Oracle Net Listener and the Oracle Database server must be running in order for the database server to receive connections.
• Starting Oracle Connection Manager
  If Oracle Connection Manager is installed, then follow these steps to start Oracle Connection Manager.
• Using Easy Connect to Connect to a Database
  Easy Connect extends the functionality of the host naming method by enabling clients to connect to a database server with an optional port and service name in addition to the host name of the database.
• Viewing Connection Strings Using the connstr Utility
  You can run the Oracle Database Connection String command-line utility (connstr) to display Oracle Database connect strings for all the available network service names.
• Connecting to the Database
  There are several methods for connecting to Oracle Database.
