‘Whenever I see an
erring man, I say to myself I have also erred; when I see a
lustful man I say to myself, so was I once; and in this way I
feel kinship with everyone in the world and feel that I cannot
be happy without the humblest of us being happy.’ Gandhi |

The EM Oracle 10g Database
Control
It is like Oracle
Enterprise Manager with more features that are new. It can
automatically alert you to new critical patches. You can use the patch
wizard to select an interim patch and see if any of your system
requires it. It is integrated with a build-in MetaLink connection.
The Oracle Enterprise
Manager Grid Control in the Oracle 10g database
Setting configuration
Step #1: Find your hostname
or IP address of your server. Ex: hostname is myserver
Step #2: Make sure that the
/etc/hosts file contains the localhost name and server name.
For example, you should
have the following two lines in your /etc/hosts.
127.0.0.1
localhost.localdomain localhost
111.222.33.4
myserver.mydomain myserver
Notice that the 'myserver'
name should be the same as your server name.
Step #3: Open your browser
and enter the following URL http://myserver:7777/em and press enter
key. This will initiate Enterprise Manager Database Grid Control.
Step#4: Enter your username
and Password. Username can be SYSTEM with its password.
Now, you should see the
Oracle EM 10g Grid Control page. By clicking on the Home, Targets,
Deployments, Alerts, Jobs, and Management System tabs, you can
navigate and monitor your databases information.
On the Oracle 10g, one more
tablespace (SYSAUX) was added. It provides a centralized location for
all auxiliary database metadata that does not reside in the SYSTEM
tablespace.
To stop the Oracle
Management Server, do the following command:
# emctl stop oms
To start the Oracle
Management Server, do the following command:
# emctl start oms
To get the status of the
Oracle Management Server, do the following command:
# emctl status oms
Using the dbconsole process
You must have the dbconsole
process running.
To start the EM Database
Control:
# emctl start dbconsole
To stop it:
# emctl stop dbconsole
To get its status:
# emctl status dbconsole
The default port is 5500
and you can access it by opening your Web browser and enter the
following URL: http://myserver:5500/em

“Nonviolence is the
answer to the crucial political and moral questions of our time;
the need for mankind to overcome oppression and violence without
resorting to oppression and violence. Mankind must evolve for
all human conflict a method which rejects revenge, aggression,
and retaliation. The foundation of such a method is love.”
Martin Luther King Jr., December 11, 1964 |
