To provide a list of all the Listener Control utility commands or provide syntax help for a particular Listener Control utility command. Commands are shown in the following example output. When you enter a command as an argument to HELP , the Listener Control utility displays information about how to use the command. To reread the listener. This command enables you to add or change statically configured services without actually stopping the listener.
In addition, the database services, instances, service handlers, and listening endpoints that were dynamically registered with the listener are unregistered and subsequently registered again. To save the current configuration state of the listener, including trace level, trace file, trace directory, and logging to the listener. Any changes are stored in listener. Before modification of the listener. This command enables you to save all runtime configuration changes to the listener.
To obtain detailed information about the database services, instances, and service handlers dispatchers and dedicated servers to which the listener forwards client connection requests. The output shows the following:. An instance named sales belonging to two services, sales1.
Service sales2. To alter the parameter values for the listener. Parameter value changes remain in effect until the listener is shut down. Parameters are shown in the example output. Moreover, when the size of the database file growing automatically from its specified size, you can use.
On the other hand, a file system is a more unstructured data store for storing arbitrary, probably unrelated data. Difference Between File a Difference Between File and Database is that a data file is a collection of related records stored on a storage medium such as a hard disk or optical disc.
While a database is a collection of data organized in a manner that allows access, retrieval, and use of that data. Database File System DBFS leverages the features of the database to store files, and the strengths of the database in efficiently managing relational data, to implement a standard file system interface for files stored in the database.
On Linux and Unix systems, the listener is implemented as a background process that you can see by issuing the ps command. For example:. On Windows NT systems, the listener process is implemented as an NT service, which you can see listed in the Services control panel. Also on Windows NT, when you start a listener for the first time, the Listener Control utility automatically creates a service for that listener. Unfortunately, the service is created without first checking listener.
After that service was created, the newly started listener read the listener. The bad part about all this is that the erroneous NT service still remains. To find out how to delete it, read Section 4. You may find it convenient to configure your server so that the Net8 listener starts automatically when the system boots. On Windows NT systems, you use the Services control panel to configure a listener to start when the system boots. On Linux and Unix-based operating systems, you need to modify the system startup scripts.
Figure 4. In Figure 4. In the resulting dialog, select Automatic as the Startup Type, as shown in Figure 4. When you have the startup type set the way you want it, click the OK button to close the dialog. Your change takes effect the next time you boot the server. Use the command SPAWN to start a program stored on the computer on which the listener is running, and which is listed with an alias in the listener. To start a listener configured in the listener.
Use the command STATUS to display basic status information about a listener, including a summary of listener configuration settings, listening protocol addresses, and a summary of services registered with the listener. The output contains:. Distributed Operation s The Listener Control utility can perform operations on a local or a remote listener.
To set up a computer to remotely administer a listener: Ensure that the Listener Control utility lsnrctl executable is installed. When issuing commands, specify the listener name as an argument. Listener Security It is important to provide security through a password for the listener. Usage Notes The Listener Control utility prompts you for the old password and then for the new one. Usage Notes This command enables you to save all runtime configuration changes to the listener.
See Also: "Listener Security". If you require this command to run the listener, please notify Oracle Support Services. Prerequisites Listener must not already be running. Usage Notes To start a listener configured in the listener. Prerequisites The listener must be running.
Note: You can combine commands in a standard text file, and then run them as a sequence of commands.
