Accessing the Oracle Enterprise Manager Database Control
At the end of a successful database creation, Oracle Enterprise Manager is
automatically launched and the database is started. At other times, provided the
dbconsole process is running on the server, Oracle DBA can navigate to your Database Control
from your client browser as follows:
1. Point your web browser to the following URL:
http://hostname:portnumber/em
For example, if Oracle DBA installed the database on a host computer named comp42, and
the installer indicated that your Enterprise Manager Console HTTP port number is
5500 (also recorded in the $ORACLE_HOME/install/portlist.ini file), enter the
following URL:
http://comp42:5500/em
If the database is up, Enterprise Manager displays the Database Control Login
page.
If the database is down and needs to be started, Enterprise Manager displays the
Startup/Shutdown and Perform Recovery page. If this is the case, click the
Startup/Shutdown button. Oracle DBA are then prompted for the host and target database
login usernames and passwords, which Oracle DBA must enter. For the database user and
password use SYS and the password Oracle DBA specified during installation.
Click OK to start the database. In the Confirmation screen, click YES to start the
database in open mode.
2. Log in to the database using a username that is authorized to access the Database
Control. This initially could be SYS or SYSTEM. Use the password Oracle DBA specified
for the account during the database installation.
The property pages across the top of the page enable Oracle DBA to access performance,
administration, and maintenance pages for managing your database. The
functionality provided by these pages is discussed in other chapters of this book.
The various sections of the Database Home page, and related links, provide a
wealth of information about the database’s environment and health. For example,
the Alerts, Related Alerts, and ADDM Analysis sections warn Oracle DBA of errors and
performance problems that are impacting the operation of your database. Oracle DBA can
click the provided links to see more detail about the problem area, and even to
obtain recommendations and SQL for resolving the problem.
