9.4. SQLDBA
SQLDBA is an Oracle-supplied utility
program that is similar in function to Server Manager. SQLDBA was
supplied with Oracle Version 6, but was made obsolete with the
introduction of Server Manager with Oracle7 Version 7.0. SQLDBA was
supplied, for compatibility purposes, through Oracle7 Version 7.2.
Functionally, SQLDBA is much like the newer Server Manager. It
provides the ability to execute SQL statements as well as to perform
monitoring of the Oracle database to which it is attached. SQLDBA is
a character-mode application; there is no graphical version, although
some basic character-mode graphics are used where available.
There are a number of differences between SQLDBA and the newer
Server Manager; some of them are
operational, but most are cosmetic. One of the most notable
differences is the behavior of the STARTUP command. When you are
using SQLDBA to start a database, any failure in the startup process
results in all operations being backed out and the database being
shut down. When you are using Server Manager, however, failure of any
step of the startup leaves the database in its current state. For
example, if an error occurs after mounting the database, Server
Manager will leave the database mounted, while SQLDBA will dismount
the database and shut down Oracle.

Manager, see Oracle Corporation's online SQLDBA to
