Welcome to Oracle Net Configuration Assistant in custom installation mode. You can configure basic elements of the network, including:
Select this option to create a listener with one or more protocol addresses. The listener is a process on the server that receives and responds to client connection requests for a database. Clients using connect descriptors configured with the same protocol addresses can send a connection request to the listener.
Note: This option is not available on clients.
Select this option to configure naming methods. When an end user connects to a database service, a connect string that identifies the service through a simple name, called a connect identifier, is used. A connect identifier can be the actual name of the service or a net service name. The connect identifier is resolved to a connect descriptor, which contains the network location and identification of the service, by a naming method. You can configure this computer to resolve connect identifiers using any of the following methods:
Additionally, if the local naming method is selected on the client, you are prompted to configure connect descriptors in a client-side tnsnames.ora file.
Select this option to configure the following:
One net service name in the tnsnames.ora file
This net service names is established for connections to external procedures.
Local naming and easy connect naming methods in sqlnet.ora file
When the client or server attempts to resolve a connect identifier, local naming is attempted first, followed then by easy connect naming.
(Server Only) Two default listener protocol addresses in the listener.ora file
One address will use TCP/IP on port 1521 and the other will use IPC for client connections to external procedures. Oracle Net Configuration Assistant also automatically configures service information for the external procedures in the listener.ora file.
For information about using the local naming and easy connect naming methods, see Chapter "Configuring Naming Methods" in the Oracle Net Services Administrator's Guide.
For information about prioritizing naming methods in the sqlnet.ora file, see Chapter "Configuring Profiles" for information in the Oracle Net Services Administrator's Guide.
For information about configuring the listener.ora file, see Chapter "Configuring and Administering the Listener" in the Oracle Net Services Administrator's Guide.
