Just as SQLPlus is used to start, stop, and manage an Oracle database, Oracle provides a command-line utility known as Listener Control to start, stop, and manage the Oracle Net Listener. The executable name for Listener Control will be one of the following:
Which Oracle tool is used is to start, stop, and manage an Oracle database in Oracle 11g?
The Oracle tool used to start, stop, and manage an Oracle database in Oracle 11g is called SQLPlus.
SQLPlus is a command-line tool that provides an interface to the Oracle Database. It is typically installed with the Oracle database server and client software.
Here are some of the primary functionalities provided by SQL*Plus:
- Start the Database: To start an Oracle database, the command 'STARTUP' is used in SQL*Plus. This command initiates the instance and mounts and opens the database.
- Stop the Database: The 'SHUTDOWN' command is used in SQL*Plus to stop an Oracle database. There are several shutdown modes, including IMMEDIATE, TRANSACTIONAL, and NORMAL, each of which determines how ongoing transactions are handled before the shutdown.
- Database Management: SQL*Plus allows administrators to execute SQL commands for database management. These could include creating, altering, or dropping database structures like tables, views, indexes, etc. It also allows executing PL/SQL blocks for procedural database programming.
To use SQL*Plus, one needs to open a command prompt (on Windows) or terminal (on Unix/Linux), type 'sqlplus', and log in with a valid Oracle database username and password.
While SQLPlus is a powerful tool, it should be used carefully, especially when issuing commands that modify database structures or data. Only authorized users, such as database administrators, should have access to SQLPlus because of the potential impact on the database's operation and data integrity.
