Oracle Server Manager is a tool included with each database for use in database administration. There are actually two versions of Server Manager: the graphical (GUI) version and the line-mode version. The line-mode version is available on every platform, while the GUI version is available on all platforms that support a GUI environment.

Server Manager can be used to administer any database running Oracle Version 7.0 or later. In order to use Server Manager, the Oracle-supplied script catsvrmg.sql must be run as SYS on the database being administered. Normally, this script is automatically executed by catproc.sql.
