Mixed Platform Architectures for Release 12

Editor Mar 15 Update:  There are a number of mixed platform architectures that are supported for Release 12 today, although certification of additional platforms is still pending.  More details added below.

Editor Update:  It turns out that our official nomenclature for these types of configurations has evolved between releases.  In Release 11i, these were called "split configurations."  In Release 12, these are now called "mixed platform architectures."

Here's a quick update for those of you who might be interested in "mixed platform architectures," where the E-Business Suite's database and application servers are deployed on different operating system platforms. 

Itanium Chip:

R12 Fully Certified Platforms

As of March 15, 2007, the following are the fully certified platforms (application and database tiers) for the E-Business Suite Release 12. See Oracle Certify for exact versions and platforms certified with E-Business Suite:
  • HP-UX Itanium
  • Linux x86 and x86-64 (32-bit OS)
  • Linux x86-64 (64-bit OS)
  • Microsoft Windows Server 2003
  • Sun Solaris Operating System (SPARC)
These platforms can be mixed together, i.e. the database tier can use any one of these platforms, and the application tier can use any one of these platforms.  So, this would be a certified combination:  database tier on HP-UX Itanium, and application tier on Linux x86-64 (32-bit OS).

Not Certified Yet... For Use on the Database Tier Only

Certifications for the following additional platforms are underway for the database tier only:
  • IBM System z Linux
  • Linux Itanium
  • Microsoft Windows Server 2003 x64
  • Microsoft Windows Server 2003 Itanium
In other words, you can't use any of these four operating system platforms for your database tier yet, but these certifications are forthcoming.  When they're certified, you'll be able to deploy any of these four platforms on your database tier only.  At that time, you will be able to mix any of these four database tiers with application tiers running on any of the existing fully certified platforms in the first list.

The certifications of the four database tier only platforms are underway now, and are expected to be released in conjunction with the R12 certification for the Database.  Firm schedules aren't available yet, but feel free to monitor or subscribe to this site for updates, which I'll post as soon as they're available.

Still Confused?

Don't worry -- you're not the only one.  As you can infer from the changes to this article, we've been working through the nomenclature around these mixed platform architectures ourselves.  If you're still struggling to get a handle on this, either log a Service Request or contact your Oracle account manager to get some help with your specific target platform architecture.


I wish to know the platforms that support 11i (oracle apps)

You can get a comprehensive listing of supported Oracle E-Business Suite Release 11i platforms by logging into Metalink > Certify > View Certifications by Product > E-Business Suite.

My customer choosed to implement R12.X in a mixed architecture:
Database on HP PA-RISC 11.11 ..
aplication tiers on Solaris 9.

In this article i notice that this kind of mixed architecture is supported.

Under metalink -> certify -> product ebusinessSuite -> R12
: i found that
When the E-Business Suite application tier is installed on a "Certified E-Business Suite Platform," the following additional platforms may be used for the database tier
only. In previous E-Business Suite releases, this configuration was referred to as a "Split Configuration Database Tier."

* IBM Linux on POWER
* IBM System z Linux
* Linux Itanium
* Microsoft Windows Server 2003 x64
* Microsoft Windows Server 2003 Itanium
* Solaris 10 (x64)

==> Since HP UX does not appear on this list, it means it is not yet supported.

mixed architecture PA-Risc and Solarisis supported or not ?

Hi, Ibrahim,

Both Solaris 9 SPARC (64-bit) and HP-UX PA-RISC are fully-certified platforms for EBS 12. This means that you can run either platform on the application tier, database tier, or both.

Hi Steven,

We would like to go with following Architecture (mixed platform) for R12 (12.1.3).

App Server - Win 2008 64 bit R2
DB - Red hat Enterprise Linux 5.x

Is this mix supported? Also is there any known performance impact going with this Architecture?


Posted by Navaneeth on July 16, 2012 at 11:31 PM PDT #

Hi, Navaneeth,

EBS 12.1.3 is certified on both of the platforms you've listed. You can look up platform certifications on My Oracle Support > Certifications tab. The certification page for each of the respective platforms has links to the appropriate documentation.

There are no performance issues with mixed platform architectures.

Hi Steven,

In our existing env, we placed DB, Conc Processing Server, Report, Admin, APPL_TOP, COMMON_TOP at Node 1. And Web Server and Forms Server are installed in Node 2. Both OS are in same platform - Solaris.
Currently we are running EBS. If Node 2 is going to change to another platform - Linux, can we still maintain same architecture as at our current existing environment? In terms of patching, we can see the problem where we need separate patches in case patching is required.
Appreciate your advice.

Thank you.

Hi Steven,

Our internal (Intranet) application Tier is running on Solaris 11. We now plan to add an external application Tier (Internet) within DMZ having its own file system on Red Hat Linux to support iSupplier, SSHR. We would like to know whether this combination is supported and certified. ?

Current Production: 2 Tier - DB (Solaris 11) and Internal App Tier -1(Solaris 11)
Future: 3 Tier - DB (Solaris 11) , Internal App Tier-1 (Solaris 11) and External only App Tier-3 (Red Hat Linux)

As long as a given physical server's operating system is certified with the target E-Business Suite release, you can deploy that in your multinode architecture.
