Prerequisites

Before starting this module, you should have:

Completed the Preinstallation Tasksmodule

Installing the Oracle9iDatabase

Perform the following steps to install the Oracle9 idatabase:

1. The Oracle Universal Installer requires 400 MB of temporary space on yourC:drive to run

successfully. If you do not have at least 400 MB on the C:drive, then update theTEMPuser

variable in your environment variables and change it to a location with the required amount ofspace. In addition, make sure that the computer has sufficient system memory (the combination

of RAM and virtual memory). If the page file size is too small, messages appear indicating that

the computer is running low on virtual memory. Check your page file size to make sure that the

initial size is 200 MBand the maximum size is 400 MB.

2. Insert yourOracle9iEnterprise Edition CD-ROMinto the CD-ROM drive. In the Autorun

window that appears, choose Install/Deinstall Products. If you do not have your laptop set up

for Autorun capability, runautorun.exedirectly from theAUTORUNdirectory on your Oracle9i

Enterprise Edition CD-ROM. You will install Oracle9 iin its own home directory. Click Nextto

accept the default Oracle_Home name and location.

3. In the Welcome window, click Next.

12. The Oracle Universal Installer displays a summary of the installation options. Make sure that you

have the required disk space available and then click Install.


13. The Oracle Universal Installer begins installing Oracle9iEnterprise Edition and related software.

Note:This process takes at least one hour. The Oracle Universal Installer also creates

installation logs as it progresses. You can view these while the installation is in progress. The log

for this installation session is located atC:\Program Files\Oracle\Inventory\

logs\installActions.log. If you install another product, the current log is copied to this file

and renamed, so there is always a history of each successive installation.


14.After the initial software is copied to the disk, the Oracle Universal Installer also automatically

configures the network for the Production database. This is done in the background. The

success of the operation is reported in the Oracle Universal Installer Configuration Tools

window. Once the network configuration has been completed, the Oracle Universal Installer

starts the Oracle Database Configuration Assistant. This assistant installs and configures the

initial database in the background as well.

For more information about the Oracle9iinstallation process, please see theOracle9i

Installation Guide.

Exploring the Oracle9iInstallation

In this topic, you will review some of the directory structures that were built for you when OracleUniversal Installer installed an optimal flexible architecture (OFA)-compliant image of the Oracle9i

software.

1. Open Windows NT Explorer and click the drive where you installed the database (for example,

D:). Select View > Refresh. Navigate to theD:\Oracledirectory. Notice that there are three

subdirectories: admin, Ora90, and oradata.

2. Navigate to theadmindirectory. The D:\Oracle\admindirectory is an OFA-compliant

directory that contains information about different database instances installed on this machine.

So far it contains one directory, orcl, for the orcl.world instance that you just created.

3. Navigate back toD:\Oracle\Ora90. This is the Oracle9isoftware directory, also known as the

Oracle9iORACLE_HOME. All the software for the Oracle9iEnterprise Edition is installed under

this directory tree.

4. Navigate to theD:\Oracle\Ora90\Network\admindirectory. This is the directory that the

networking files are stored in.

5. Open thelistener.orafile generated during the Oracle Universal Installer installation of

Oracle9i

.

6. Notice that the listener has been set to listen for three different types of connections:

External processes called from the server, using InterProcess Communication (IPC)

Oracle Net connections from across the network, using TCP/IP, on port 1521

The listener has also been configured with two services:

An external process server for external procedure calls

A database service for the ORCL.WORLDinstance

Yourlistener.orafile should look like the following:

# LISTENER.ORA Network Configuration File:

d:\oracle\ora90\network\admin\listener.ora

# Generated by Oracle configuration tools.

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC3))

)

10/19

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = meyoung-lap)(PORT = 1521))

)

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = d:\oracle\ora90) (PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = orcl.world)

(ORACLE_HOME = d:\oracle\ora90)

(SID_NAME = orcl)

)

)

7. Closethe file when you are finished.

8. Open thetnsnames.ora file generated during the Oracle Universal Installer installation of

Oracle9i. Change US.ORACLE.COM toWORLD. This is done for simplicity purposes. The

examples used through out the series will use this domain name however you may use what

ever you would like.

# TNSNAMES.ORA Network Configuration File:

d:\oracle\ora90\network\admin\tnsnames.ora


EXTPROC_CONNECTION_DATA.WORLD= (DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC3))

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

)

ORCL.WORLD= (DESCRIPTION =

(ADDRESS_LIST =


)

(CONNECT_DATA = (SERVICE_NAME = orcl.world)

)

)

INST1_HTTP.WORLD= (DESCRIPTION =

(ADDRESS_LIST =


)

(CONNECT_DATA =

(SERVER = SHARED)

(SERVICE_NAME = MODOSE)


19 6/7/2016


11/19

(PRESENTATION = http://HRService)

)

)

9. Save your work and close the file.

10. Open theSQLNET.ORAfile generated during the Oracle Universal Installer installation of

Oracle9i. Change the US.ORACLE.COMentry toWORLD. The DEFAULT_DOMAINname mustmatch the domain name in yourTNSNAMES.ORAfile.

# SQLNET.ORA Network Configuration File:

d:\oracle\ora90\network\admin\sqlnet.ora


NAMES.DEFAULT_DOMAIN =WORLDSQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

11. Save your work and close the file.

12. Navigate to theD:\Oracle\Ora90\Databasedirectory. This directory contains the password

files and the default initialization files for each instance created on this machine.

13. Open theinitorcl.orafile. Notice that it contains a reference to the "real" initialization file at

D:Oracle\Admin\orcl\pfile\initorcl.ora .

14. Navigate back toD:\Oracle\Oradata\orcl. This is the directory that contains the data files

for each instance that you create on this machine. Explore the contents of this directory.

15. Select Start> Settings> Control Panel. Scroll down to the list of the services that were added

as a result of your installation.

16. Now that you have installed Oracle9i, you should rebootthe machine.

Testing the Oracle9iInstallation

In this section you will test the installation of the Oracle9idatabase using Enterprise Manager, which

combines all of the management tools together into one product.

1. Select Start > Programs > Oracle-OraHome90 > Enterprise Manager Console.

2. In the Oracle Enterprise Manager Console login window, make sure that Launch standaloneis

selected and then click OK. Note: You can launch Enterprise Manager to immediately connect to

the database for direct database administration. No configuring is necessary. From this Login

window, you can also connect to the Oracle Management Server (OMS) however you need to
