  Oracle Database Tips by Donald Burleson

Dedicated Connection

In a dedicated connection the client must have an application that can use Oracle Net, Oracle Net and a network transport protocol such as TCPIP. Once the required software is installed the DBA edits or installs a proper tnsname.ora file in the ORACLE_HOME\network\admin directory and the user should be able to connect. You can test connectivity on a TCPIP network using the ping system utility and the network address or name of the server to see if the server can be reached from the current client. Once the Oracle Net application is installed and configured you can test connectivity using the tnsping utility and the database connection alias (service name).

In a dedicated connection the client requests a connection at the specified port (usually 1521) the listener process accepts the request, checks to see if it has the database in its list of instances and then passes the connection directly to the database. There are no special initialization parameters required for a dedicated connection.
