Turbocharging Your EBS 12.0 Techstack Upgrade

All three of the major new technology stack components included in Oracle E-Business Suite Release 12.1.1 are also certified with Release 12.0.  You could manually upgrade each of these R12.0 techstack components yourself.  But now that Release 12.1.1 is out, why bother with that time-consuming approach when there's an easier and faster way?

You can use the EBS 12.1.1 Rapid Install to upgrade just the application and database tier technology stack components in your existing EBS 12.0 instance. Your technology stack components are upgraded to the same versions delivered with EBS 12.1.1 while leaving your EBS 12.0 product code (e.g. Financials, Supply Chain) untouched.

Running the Rapid Install with the -techstack option

Using the rapidwiz -techstack option with the EBS 12.1.1 Rapid Install provides options to upgrade the applications and database tier components for the following ORACLE_HOMEs:
  1. Application Server 10g OC4J to 10.1.3.4 (Applications tier)
  2. Application Server10g Forms and Reports to 10.1.2.3 (Applications tier)
  3. Database Release 10gR2 to 11gR1 version 11.1.0.7 (software and configuration files only on the DB tier. DB upgrade and post install steps to be performed separately)
From the first screen below, you can select the respective tier and proceed with the upgrade.

1. Upgrading the Database Technology Stack

Before selecting the database tier technology stack upgrade, make sure that your environment meets the minimum operating system prerequisites for running the 11gR1 Database.

If you choose the database tier upgrade, the wizard takes inputs for the Database host, Oracle SID, ORACLE_HOME and OS user related inputs.

It creates the new ORACLE_HOME with the associated Release 12.1.1 patches for the 11gR1 11.1.0.7 Database.  The installation then proceeds with installing the 11gR1 database software and the required configuration files for the E-Business Suite.

After the installation and configuration is complete, you need to complete the remaining DB upgrade steps using Section 1 and Section 2 of Interoperability Notes for 11gR1 with EBS R12.

2. Upgrading the Applications tier Technology Stack


If you choose to upgrade your applications tier, the Rapid Install wizard requires the CONTEXT file for your existing configuration. Point the wizard to the Application tier context file for your applications tier, e.g. $INST_TOP/appl/admin/<context name>.xml.

The wizard identifies the respective ORACLE_HOMEs from the context file and proceeds to upgrade these components.

After validating and confirming the information, the installer proceeds to upgrade the components in the two Oracle Application Server 10g 10.1.3 and 10.1.2 ORACLE_HOMEs.

After all of the new Oracle Application Server 10g files are laid down in your filesystem, the Rapid Install wizard validates the installation. A green tick on the Validation window means the installation passed the post-install checks.

Once you've run this upgrade on all of the Application tier nodes in your EBS instance, you're done!  Automated, validated, and fast.

Hi Prasad,

Very good article, save lot of time...but i have a problem with this method.
my system OUL5x64 r12 12.0.6
want to upgrade techstack from 10.1.2.0.2AS and 10.1.3.0.0 AS to 10.1.2.3 AS and 10.1.3.4AS
the processes went exactly as the screens on this article and successful finished.
when checking the AS versions in $ORACLE_HOME/config/ias.propertiers (in 10.1.2 and 10.1.3 HOME) they are still in the old versions.
tried it again and got the same result.
Would you please advise.
Thanks-Tom

Tom,

Have you pointed to the right context file for picking up the 10.1.3. and 10.1.2 Oracle Homes?. Did you verify the post install logs and also through UI?. If sure about it, please log a bug against 1745 and INSTALL with your exact platform details and we will take it up from there. I tried it several times on Linux before posting this article and it worked fine.

Hi Prasad,

i've opened aTAR with oracle about this issue and we did OWC
the Analyst was doing the upgrade along with me and at the end it did not upgrade any thing. Yes i did point to the correct XML file.
i am on oul5x64 (oracle VM) ebs R12 12.0.6
i did this install more than 3 times and every time , i have the same result as your screen shots, but nothing got upgrade. The analyst will check with the backend and will get back to me.

Thanks-Tom

Dominic West:

Would the techstack upgrade allow us to deploy a web service in the e-biz AS rather than using a seperate web services manager?

We don't need the full SOA integrated gateway as installed in 12.1.1

Thanks
Dominic

Hi, Dominic,

Our Applications Technology Group tells me that the only web services supported through the Integration Repository will be those generated via our SOA provider and deployed in the EBS OracleAS home. This is being targetted for a future EBS R12 release.

There are no current plans to support web services that are not generated and deployed by the EBS Integrated SOA Gateway. We do not currently plan to support the deployment of custom web services for a custom PL/SQL API via JDeveloper.

Gerry McGreevy:

We are at 12.0.4 (db 11.1.0.6). We are thinking of upgrading to 12.1.1, and are interested in the steps you outlined in your blog post here.

However, we are concerned about continued support by Oracle. Is such a method supported? Are there more detailed upgrade instructions other than the broad outline in your blog (ie. We are wondering what functional steps are necessary, Pre-steps, post-steps, etc). Is there such a list?

Thanks
Gerry McGreevy

Hi, Gerry,

This is a fully-certified and supported option. For complete documentation on this feature, see page 1-17, "Installing a New Technology Stack" and page 4-1, "Installing Technology Stack Components" in the "Oracle Applications Installation Guide: Using Rapid Install, Release 12" manual:
