Oracle Grid
What is the Oracle 10g
Database Grid?
Yesterday was Internet
and today is Grid. It looks like the technology
finds its way to hang on something to grow. Now,
there is a committee called the Global Grid Forum (GGF)
that is developing standards for Grid computing.
The following are some
of the most important features that enable Grid
computing at the Oracle 10g Database level:
-
Automatic Storage
Management
-
Portable
Clusterware
-
High-Speed
InfiniBand Network Support
-
Real Application
Clusters and automatic workload management
-
Resource Manager
-
Oracle Streams
-
Centralized
Management with Enterprise Manager Grid Control
-

What is OEM 10g?
It is Oracle
Enterprise Manager with more new features. 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.
Navigate the Oracle Enterprise Manager Grid Control
in the Oracle 10g database
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
