Introduction

This paper will walk you through the steps of installing Oracle Database 11g release 2 (Oracle version 11.2.0) in aLinu environ!ent. "bout #0$ of the !aterial presente% here applies to other platfor!s as well. &verything you rea%in this paper is han%s on' rollupyoursleevesan%getbusy !aterial for Oracle users who want to get anOracle

%atabase up an% running uickly without rea%ing hun%re%s of pages of %ocu!entation an% *rea%!e+ files.

These steps are !eant to get you up an% running as fast as possible' while leveraging best practices in or%er to set upa scalable' robust %atabase environ!ent that offers high perfor!ance. ,n or%er to keep the steps reasonably si!plethis paper %oes not cover -eal "pplication lusters (-")' nor %oes it cover Oracle ,nternet Directory (O,D)'"uto!atic /torage anage!ent ("/)' or ri% ontrol.

,n this paper we will install the 11.2.0.1 release of Oracle Database 11g. This is the base %istribution of OracleDatabase 11g release 2. e sure to check Oracle /upport3s etalink at http455!etalink.oracle.co! to see if a newerpatch set has been release% since this paper was publishe%. 6ou will nee% a vali% usto!er /ervice ,%entifier (/,)nu!ber in or%er to access the etalink website.

7e ran our Oracle installations on servers euippe% with ,ntel 8eon processors running -e% 9at &nterprise Linu &/release : (Tikanga)' up%ate ; (=;). Oracle Database 11g is supporte% on other processor architectures an% Linu%istributions as well. ?ote that with -e% 9at &nterprise Linu' the &/ an% "/ varieties are supporte% while 7/ is not.

There are four phases to getting Oracle up an% running on your server4

1. @repare the server

2. ,nstall the Oracle software an% latest patch set

A. reate a %atabase

;. o!plete the server configuration

7e will walk through these phases one at a ti!e' %etailing all the steps involve%. The en% result will be a very usable%atabase that can be scale% up uite large' an% an Oracle installation that follows in%ustryrecogniBe% bestpractices. Of course' every i!ple!entation is uniue' an% you will nee% to evaluate each step carefully against yourparticular reuire!ents. 9owever' this paper will get you off to a very soli% start.

The author wishes to acknowle%ge that this paper %raws heavily fro! the previous Database /pecialists' ,nc. paperC,nstalling an% onfiguring Oracle Database 10g on the Linu @latfor!C by -oger /chrag thanks -oger

Prepare the Server

These steps configure your %atabase server so that it will be rea%y to accept the Oracle software an% %atabase. ,nthis section' we will !ake sure your server !eets Oracle3s !ini!u! reuire!ents' create a Linu user an% group to*own+ the software' an% create so!e %irectories that will be use% by the Oracle software an% %atabase. "ll of the

steps in this section are run as the root user.

1. ake sure that your har%ware platfor! (processor architecture) is certifie% by Oracle orporation for usewith Oracle Database 11g release 2' an% that you have acuire% the correct %istribution of Oracle softwarefor your har%ware platfor!.

Install the Oracle Software and Latest Patch Set

These steps install the Oracle software an% latest patch set on your server. "s of this writing' Oracle release11.2.0.1.0 is the only version of Oracle Database 11g release 2 available for %ownloa% fro! Oracle Technology?etwork or available on D or DID !e%ia. "t so!e point in the future' Oracle will release latest patchsets (e.g.11.2.0.2' 11.2.0.A' etc.) however the first such patchset has not yet been release. Therefore' we will install Oracle

release 11.2.0.1.0. Once Oracle have release% a patch set you shoul% apply the patchset on top of the base11.2.0.1.0 release. efore procee%ing with the steps in this section' you shoul% check Oracle Technology ?etwork(http455www.oracle.co!5technology ) an% Oracle /upport3s etalink (http455!etalink.oracle.co!) to see if any 11grelease 2 patch sets are available.

The Oracle Fniversal ,nstaller will suggest creating a %atabase at the sa!e ti!e that it installs the Oracle software."lthough we %o not have any latest patchsets to install' we will hol% off on the %atabase creation until a later stepsince that is the preferre% seuence of events once a 11g release 2 patch set is eventually release%.

,n this section' we will prepare the oracle user3s environ!ent' run the Oracle Fniversal ,nstaller an% ti%y up a few!inor loose en%s. "ll of the steps in this section' ecept where note%' are run as the oracle user.

1. &%it the oracle user3s login file on the %atabase server so that the environ!ent will be configure%auto!atically on login. ,f you are using ash shell' then e%it .bash>profile. ,f you are using ourne or Korn

shell' then e%it .profile. 6ou can also use shell an% e%it .cshrc' but the synta will be %ifferent fro! theea!ples you see here. or now' we will har%co%e certain things. ut after we create a %atabase' we willco!e back an% eli!inate all har% co%ings. 9ere is what we a%%e% to our .bash>profile for the install4

20. ,f you ha% to set your D,/@L"6 variable !anually in the previous step' then ensure that the 8 server on your

k. During the installation an &ecute onfiguration /cripts win%ow will appear. The installation willbe pause% at this point' waiting for you to run scripts as root. (The first ti!e you install Oraclesoftware on the %atabase server there will be two scripts to run as root' while a%%itionalinstallations only reuire one script to be run as root.) 6ou shoul% open another win%ow' log in tothe %atabase server as root' review the scripts to be run thoroughly' run the scripts' an% click OKin the &ecute onfiguration /cripts win%ow.

l. Once the root scripts have ran the installer will %isplay the inish win%ow' click lose to en% theinstallation.

2A. "t this point we are rea%y to patch the Oracle software installation with the latest !aintenance releaseavailable. Log onto Oracle Oracle /upport3s etalink (http455!etalink.oracle.co!) an% %ownloa% the latestpatch set for Linu =; or whichever processor architecture your %atabase server uses. "s of this writing'there are no patch sets available so we will skip this step' once a patch set beco!es available we willup%ate this %ocu!ent with the instructions for the patch set.
