Installation steps of Oracle database 11g Release 2.
 In this post I will describe the installation steps of Oracle database 11g Release 2
(32-bit) on Windows Server 2007 (32-bit).
--------------------------------------
- Download Oracle Database 11g release 2.
-http://www.oracle.com/technology/software/products/ warehouse/index.html.
- Run the setup.exe
 Provide your email address to be informed of security issues, install the product
and initiate Manager.
Select any of the following install steps.
1. Oracle Database 11g Release 2 introduces a new option that enables you to
specify the type of system on which the database is installed.
2. If you are installing on a laptop or a desktop, then select the Desktop Class
option;

3. otherwise, select the Server Class option to install on a server. This installation
class is for servers, such as you would find in a data center, or used to support
enterprise-level applications.
Typical install configuration.

The above errors came because I didn't unzip the 2 files in the same folder.
Download the Oracle win32_11gR2_database_1of2.zip andwin32_11gR2_database_2of2.zip unzip both
files in same folder and then run the setup again.

Installation of Oracle Database was successfull.

Configuring the listener
Run Net Configuration Assistant to configure the listener. It is available under the Oracle menu
on the Windows Start menu as shown in the following image:

The welcome screen will offer us four tasks that we can perform with this assistant.
We’ll select the first one to configure the listener, as shown here:
The next screen will ask you what we want to do with the listener. The four options are as
follows:
• Add
• Reconfigure
• Delete
• Rename

The next screen is the protocol selection screen. It will have TCP already selected for us, which is
what most installations will require.

To change or not change the default listener port 1521

last step.
It will ask us if we want to configure another listener.
Since we only need one, we’ll answer "no" and finish out the screens by clicking on the Finish
button back on the main

If selecting a create and configure the database the database is not install then
click on retry button and next click on skip button in final click on finish button
We have to try second option two install database configure assistance:
Go to the START Menu as shown in the following image:-
The first step is to specify what action to take
1. Since we do not have a database created, we’ll select the Create a Database option
2. If there was a database already created, the options for configuring a database or
deleting a database would be selectable
3. Templates can be managed with the Database Configuration Assistant application, which
are files containing preset options for various database configurations.

This step will offer the following three options for a database template to select:
° General Purpose or Transaction Processing
° Custom Database
° Data Warehouse
NOTE:-BUT WE HAVE TO SELECT A CUSTOM DATABASE
This step of the database creation will ask for a database name.
This step of the database creation process asks whether we want to configure Enterprise
Manager.

NOTE:-New in the 11gR2 version of the DBCA is the additional tab on this screen for the
Automatic Maintenance option.
On this screen we can set the database passwords on the system accounts using a
different one for each account, or by choosing one password for all four
 Click on the option to Use the Same Administrative Password for All Accounts and enter a
password
 This step is a combination now of the old steps 6 and 7 of the installation. It is
about storage and specifying the locations where database files are to be created.

CLICK ON NEXT
CLICK ON NEXT
The next screen is for configuring recovery options.
CLICK ON NEXT
This step is where we can have the installation program create some sample schemas in the
database for our reference, and specify any custom scripts to run
CLICK ON NEXT
The next screen is for Initialization Parameters.

In this step set sizing 16384 .and click on next
CLICK ON NEXT
CLICK ON NEXT

The final step has the following three options, and any or all can be selected for creating
the database:
° Create the database directly
° Save the creation options as a template for later use
° Save database creation scripts that can be used later to create the database
CLICK ON NEXT
The Next button is grayed out since this is the last screen. So click on the Finish button to
begin creating the database using the selections we’ve just chosen

Click on ok
INSTALL A DBCA GIVE A PASSWORD AND UNLOCK THE ACCOUNT:

CLICK ON OK AND EXIT
Configuring the repository and workspaces
1. We are going to use the Repository Assistant application to configure the repository,
create a workspace, and create the objects in the repository that are needed for OWB to
run.
2. The Repository Assistant application is available from the Start Menu under the
Warehouse Builder | Administration submenu of the Oracle program group as shown
here:
3. The Repository Assistant application is available from the Start Menu under the
Warehouse Builder | Administration submenu of the Oracle program group as shown
here:

CLICK ON REPOSITORY ASSISTENCE THEN CLICK ON
NEXT
We’ll launch the Repository Assistant application on the server (the only machine we’ve
installed it on) and the first step it is going to ask us for is the database connection
information—Host Name, Port Number, and Oracle Service Name — or a Net Service
Name for a SQL*Net connection.
Determining what port your listener is listening on
Open a command prompt window and type in the following command: C:>lsnrctl
LSNRCTL> status
Finding your database instance name
window and type in the following command: C:>lsnrctl

LSNRCTL> service
2. Now that we’ve determined the connection information for our database, we’ll move
along to step 2 of Repository Assistant. It asks us what option we’d like to perform of the
following:
° Manage Warehouse Builder workspaces
° Manage Warehouse Builder workspace users
° Add display languages to repository
° Upgrade Repository to current release of Warehouse Builder
° Manage J2EE User account ° Manage Optional Features
We’re going to select the first option to manage workspaces and move along to the next step.
This step asks us what we’d like to do with workspaces: create a new workspace or drop an
existing one.

This brings us to step 4 of the process, which is to specify an owner for the workspace
This step will depend on which option we specified in step 4. If we are creating a new user,
it will ask us for an existing user with DBA privileges in the database.

Step 6 is new with release 11gR2 of the Warehouse Builder.
This step will ask for the password for the OWBSYS user

Click NEXT Button
This step is to select a base language for the repository
