authentication method

A security method that allows you to have high confidence in the identity of users, clients, and servers in distributed environments. Network authentication methods can also provide the benefit of single sign-on for users. The following authentication methods are supported in Oracle9i and Oracle8i, depending on whether or not Oracle Advanced Security is installed:

• CyberSafe

• KERBEROS(v5)

• RADIUS

• SSL

• Windows NT native authentication

Change the Oracle Context

When Oracle Net Manager is started, the objects displayed in the Directory > Service Naming folder are the Oracle service entries contained in the default Oracle Context established during directory usage configuration with the Oracle Net Configuration Assistant. You can create and modify entries for another Oracle Context for which you have authentication.

To change the current Oracle Context:

1. Choose Command > Directory > Change Current Context. The Choose a New Context dialog box appears.

2. From the Directory Naming Context list, select the directory entry that contains the Oracle Context you want to view.

3. From the Oracle Context list, select the Oracle Context, and then choose OK. If modifications were not saved to the current Oracle Context, a Save dialog box prompts you to save changes.

client load balancing

Load balancing, whereby if more than one listener services a single database, a client can randomly choose between the listeners for its connect requests. This randomization allows all listeners to share the burden of servicing incoming connect requests.

cman.ora file

A configuration file that specifies protocol addresses for incoming requests and local and remote commands, as well as Oracle Connection Manager parameters. The Oracle Net Manager does not support configuration of this file. It must be configured manually.

The cman.ora file must reside in one of the following locations:

1. The directory specified by the TNS_ADMIN environment variable If the TNS_ADMIN environment variable is not defined as a variable on Windows NT, it may be in the registry.

2. The node's global configuration directory. For Sun Solaris, this directory is /var/opt/oracle. Windows NT does not have a central directory.

3. The $ORACLE_HOME/network/admin directory on UNIX or the ORACLE_HOME \network\admin directory on Windows operating systems.

For more information, see Chapter 11, Configuring and Administering Oracle Connection Manager, in the Oracle10i Net Administrator's Guide.

Command menu

The Command menu enables you to perform the following operations:

Directory

This submenu contains commands the perform actions to a directory server:

Element	Description
Change Current Context	Choose to select a different Oracle Context than the current one. The Oracle Context is a subtree in the directory that stores Oracle entries, including database services and net service names for use with directory naming. When a new Oracle Context is selected, objects in the navigator's Oracle Net Configuration > Directory > Service Naming folder display for the new Oracle Context.
Set Authentication	Choose to set authentication credentials to the directory server.
Export Net Service Names	Choose to launch the Directory Server Migration Wizard. This wizard exports net service names stored in a tnsnames.ora file to a directory server.

Note: The Directory menu only displays if access to the directory has been configured. For more information about directory access configuration and other requirements, see Directory Naming Requirements for Oracle Net Manager.

Test Service

Choose to connect to a database service using connect descriptor information stored in a tnsnames.ora file or a directory server.

Configuring a Connect Descriptor for External Procedures

External procedures are procedures that are called from another program, but are written in a different language. An example would be a PL/SQL program calling one or more C routines that are required to perform special-purpose processing.

In order for the Oracle database to connect to an external procedure, the database server must be configured with a net service name to access external procedures.

Note: Oracle Net Configuration Assistant automatically creates a net service name for external procedures during installation.

To configure a database server for external procedures:

1. Ensure that the listener is configured for external procedures, as described in Configure External Procedures for the Listener.

2. Create a net service name in the tnsnames.ora file on the database. Ensure that the connect descriptor information matches the information configured for the listener.

3. Choose File > Save Network Configuration.
