UPGRADING ORACLE APPLICATION 11I

TO E-BUSINESS SUITE R12

Overview of upgrade to R12

Upgrading an application from 11i to R12 involves, upgrading the database side,

upgrading the middleware techstack and upgrading the application side.

Supported upgrade path for application side upgrade is as given below.

In case of database upgrade, you have to upgrade the database to 1gR2 !1.2.".

#ecause application R12 can be used only with 1g database.

Upgrade Process

$ll upgrade functionality has been consolidated into a single uni%ed upgrade driver

that performs the upgrade without reliance on the information formerly captured on

the $utoUpgrade screens.

Rapid Install provides the most up&to&date, certi%ed version of 'racle $pplications

products, along with the certi%ed technology stack components. In an upgrade, it

creates the new %le system for the application !middle" tier components and the new


2/23

%le system for the database. $fter the upgrade, you run Rapid Install again to

con%gure servers and start services.

$n upgrade also includes various manual steps, including those that direct you to run

scripts or apply patches. (ou rely on $uto)atch to apply all patches, including the

uni%ed driver that performs the upgrade to Release 12.

Upgrade Steps in brief

*ere are the + simple steps, briey presented below for upgrade. -hese steps are at

very high level of abstraction. e will detailed each steps as we move on further.

1" Understand installed components, system si/ing information, 0S considerations

2" )repare for upgrade using Upgrade anual Script!-US".

3" Upgrading to R12. -his includes upgrading the database and applying the re4uired

patches through $uto)atch.

+" )ost&Upgrade process. 5omplete the upgrade process by applying the latest RU)

patches to keep the system most current.

e wont be considering the functional upgrade task here.

Upgrade steps in detail

1) Understanding installed components

-echnology Stack 5omponents

Rapid Install automatically installs and con%gures the re4uired technology stack

components for both the database tier and the application tier.

-he database tier technology stack for both a new installation and for a system

upgrade is based on 'racle1g Release 2.

8atabase #ackup

EEE e strongly recommend that you back up your entire system before you begin

the upgrade. EEE

8atabase Initiali/ation )arameters

Initiali/ation parameters re4uired at each stage of the upgrade may vary depending

on when you upgrade your database. Review the re4uirements for these parameters

before you begin. Refer to metalink note I8 3DCD.1 for initiali/ation parameters.

5hange the following initiali/ation parameters as speci%ed below for upgrade

process. 'nce the upgrade process completes, reset the parameters back.

ake sure that the temporary tablespace you have is locally managed and not

-he Upgrade anual Script !-US" e@amines your current con%guration and creates

a report that lists upgrade tasks that do not apply to your system. -his report

contains information that is uni4ue to your system con%guration, so its output is

relevant to your individual upgrade. 'mitting the steps listed in the -US report can

signi%cantly reduce upgrade downtime.(ou create the -US report by applying a

Release 11i patch, which loads obGects into your $))S schema that -US uses to

e@amine your $pplications con%guration. (our current $pplications environment is

not aPected.

#elow are the list of steps I am mentioning, which are the re4uired steps. I am

skipping the conditional steps here, Gust to make it brief. (ou can as well check the

oracle documentation for the complete steps.

in 'racle applications 11i post to have detailed steps. -he database version should

be 1.2..2

$fter running this wi/ard, you will %nd that your e@isting application is intact and also

a new %le system has been created for you.


21/23

$ll your services should be up and running. (our 11i application should be intact. (ou

might face an issue, that services !specially $pache" wont come up and your UR

wont open. In this case you can check if the services get started from WinstX directory

that got created after you run the wi/ard.

(ou can go to location Mu1MappMapplmgrMinstMappsMZ-'=-$S?MadminMscripts and

run adstpall.sh script from that location. If the services were started from this

location, then it will be stopped. -hen you can start the services back from

Y5''0=-')MadminMscriptMZ-'=-$S? location.

$lso during running of the wi/ard con%guration information will be written to

following %les. you can check at your prompt and it will list the con%guration %les.
