Configuration Management Tools
See the Oracle Enterprise Manager documentation set and online help for information about using Oracle Enterprise Manager Navigating Oracle Net Manager The Oracle Net Manager interface includes two panes, a toolbar, and various menu items. Panes The Oracle Net Manager interface has two panes: the navigator pane and the right pane. Navigator Pane The navigator pane provides a graphical tree view of network objects and the objects they contain, organized in hierarchies of folders. You can use the navigator pane to view, modify, add, or delete objects in each folder. The navigator pane functions the same way as it does in other Oracle Enterprise Manager applications.
That is, the navigator pane lets you:. Expand and contract folders so that you can navigate to the network object you want to monitor or manage. Examples of objects are connect identifiers, listeners, and profiles. Right-click an object to perform operations on the object. When you expand a folder, you see a nested list of objects and folders.
When a object is selected, information about the object is displayed in the right pane of the Oracle Net Manager. Lists the main folders in the navigator pane. Table 6-1 Oracle Net Manager Navigator Pane Folders Option Description Local Displays networking elements configured in local configuration files:. Net service names in the tnsnames.ora file. Listeners in the listener.ora file. Profile in the sqlnet.ora file Directory Displays connect identifiers configured in a directory server Right Pane The right pane contains property sheets that enable you to configure network components.
XREF to 5-2 shows the Service Identification property sheet used for connect identifier configuration. Toolbar The toolbar contains buttons that correspond to the network objects in the folder hierarchies. The toolbar buttons are enabled depending on the objects viewed or selected in a pane. Move the mouse cursor over a toolbar button to display the description of the button's function. The toolbar buttons are: Create This button creates new connect identifiers, listeners objects under the Directory or Local Service Naming, Listeners folders.
Delete This button deletes connect identifier and listener objects under the Directory or Local Service Naming and Listeners folders. Verify Connectivity This button verifies the connectivity of a selected connect identifier to an Oracle database service. During a connectivity test, a connection to a database service is made by using connect descriptor information stored in a directory server or a tnsnames.ora file. Help The Help button opens the Oracle Net Manager online Help. Menus You use Oracle Net Manager menus to perform actions, such as testing connectivity to an Oracle database, and to open wizards and dialog boxes. The following list describes the items available under each menu.
File Menu describes the contents of the File menu. Table 6-4 Command Menu Contents Option Description Directory The Directory submenu contains the following menu items: Change Current Context: Enables you to change the current. The Oracle Context is a subtree in the directory that stores Oracle entries, including net entries, 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: Enables you to set authentication credentials to the directory server Export Net Service Names: Launches the Directory Server Migration Wizard. This wizard exports net service names stored in a tnsnames.ora file to a directory server. Test Service Connects to a database service using connect descriptor information stored in a directory server or a tnsnames.ora file Help Menu describes the contents of the Help menu.

Describes the key differences between the tools. Oracle Net Configuration Assistant is provided primarily to configure basic network components during installation, including:. Listener names and protocol addresses.
Naming methods the client will use to resolve connect identifiers to connect descriptors. Net service names in a tnsnames.ora file. Directory server usage Oracle Net Configuration Assistant runs automatically during software installation, as described in your Oracle installation guide.
It can also be run after installation in standalone mode to configure naming method usage, the listener, net service names in the tnsnames.ora file, and directory server usage in a similar way that is provided during installation. To start Oracle Net Configuration Assistant:. On UNIX, run netca from $ORACLEHOME/bin.
On Windows, choose Start Programs Oracle - HOMENAME Configuration and Migration Tools Net Configuration Assistant. Table 6-7 Oracle Net Configuration Assistant Option Description Listener configuration Click to create modify, delete, or rename a listener. Naming Methods configuration Click to configure this computer to resolve connect identifiers to connect descriptor through one or more of following naming methods:.
Local naming. Directory naming. Host naming. Network Information Service. Cell Directory Service Local Net Service Name configuration Click to create, modify, delete, rename, or test connectivity of a connect descriptor stored in a local tnsnames.ora file.
Directory Usage Configuration Click to configure a directory server for directory-enabled features. Listener Control Utility The Listener Control utility enables you to administer the listener. The basic syntax for this utility is as follows: LSNRCTL command listenername For example, the following command starts a listener named lsnr: LSNRCTL START lsnr You can also issue Listener Control utility commands at the LSNRCTL program prompt. To obtain the prompt, enter lsnrctl with no arguments at the operating system command line.
When you run lsnrctl, the program is started. You can then enter the necessary commands from the program prompt. For example: lsnrctl LSNRCTL START lsnr.
