E-Business Suite Release 11i Certified with OEL 5, RHEL 5, SLES 10

[June 10, 2008 Update:  Added link to Oracle Linux Technology Center, where you can find more information about additional support options for various versions of Linux]

Oracle E-Business Suite Release 11i ( is now certified on the following new operating system platforms on the x86 architecture:
  • Oracle Enterprise Linux (OEL) 5
  • Red Hat Enterprise Linux (RHEL) 5
  • SUSE Linux Enterprise Server (SLES) 10
For full details about operating system patches and other prerequisites for this certification, see:

Hello, Zia,The permutation space = all the operating system platforms and their versions * all of the E-Business Suite versions * E-Business Suite application products * techstack components * techstack versions. The cartesian set of all of those combinations is vast, and represents far too many combinations to summarize in a single document.  We capture this information in a database called CERTIFY, which is available to all Oracle Metalink users (and Oracle employees).  It's a bit tricky to use (since it was originally developed many years ago), but is the authoritative source for every question about E-Business Suite techstack certification.Regards,Steven

Hello architects. Is there a single document somewhere that lists all certified techstacks for EBS 11i/R12?

Hi Steven,
There are customers still running 11.5.10 instance.Can we expect 11.5.10 certification on RHEL 5.


Posted by Phani K on June 13, 2008 at 06:07 PM PDT #

Hello Phani -
The minimum Oracle database version certified with RHEL 5 is 10gR2 (10.2.0), so 11.5.10 users are required to upgrade their installed db to this version which in turn (see ML Note: 362203.1) requires the 11.5.10 Consolidated Update 2 (CU2) and thus effectively upgrades the EBS system to This is equivalent to what 'Maintenance Packs' did in prior 11i releases..
So, the vanilla 11.5.10 release with 9i DBMS (without CU2, and other requirements) cannot be supported on RHEL 5.

Hi Steven,

Is there any information on certification of Oracle E-Biz R12 on RHEL5.1.

Thanks in advance

Hello Prabhu -
The certification of EBS Release 12 on RHEL 5.1 is currently in progress - unfortunately we cannot divulge any ETAs, etc. due to Oracle's rules on public communications. See Steven's blog article:

Posted by John A on July 17, 2008 at 07:04 AM PDT #

I would like to confirm that RHEL5 is certified for on the Application Tier (not concerned with the database tier) and that Oracle VM is not a prerequisite.

Reason: Metalink currently states that RHEL 4 & 5 require Oracle VM (implies it by listing RHEL and Oracle VM alonside in the same field display). This discrepancy was verified by our local Oracle office.


Posted by Henry Y on July 17, 2008 at 10:49 PM PDT #


I agree that those Certify matrices on Metalink are a bit confusing.

I confirm that RHEL 5 *is* certified for for both the Application Tier and Database Tier. Oracle VM is *not* a prerequisite for RHEL 5.

We're working on getting those matrices reformatted to clarify this.

can we make a clone for oracle application R from OEL v4 update 5 to OEL v5 or vice versa?

Thank you

Posted by bahaa Ahmed on July 23, 2008 at 10:42 PM PDT #

Hi there -
EBS cloning between OEL 4 and OEL 5 is fully supported - please review the 11i cloning doc (ML Note: 230672.1) in conjunction with the Installation Update Notes (ML Note: 316806.1) for requirements, etc.

Posted by John A on July 25, 2008 at 06:43 AM PDT #

Dear John,

Thanks for your reply.

I checked the documents you mentioned, but i didnt find any statement specifieds clearly that cloning for EBS 11i from OEL4 to OEL5 or vice verse is supported or not.

I wonder if you have for any chance did a clone as per the above?

Thanks a lot in advance

Posted by Bahaa M on July 30, 2008 at 04:46 PM PDT #

Cloning from the (n-1) to n version of an OS (so, OEL 4 to OEL 5 in this case) is done as part of the certification process for the newer OS.

The 11i FAQ on cloning (ML Note: 216664.1) states the following under bullet point 13:

13. Can I clone from one operating system version to another?

Yes, if the target system platform is binary compatible with the source system platform. For example, if you have an existing single-node Oracle Applications system on Solaris 2.6, you could clone it to a node running Solaris 8, but not to a node running HP-UX. Note that cloning from a higher version of a platform to a lower version is not supported, for example, from Solaris 8 to Solaris 2.6.

Dear All,

Is it possible to install the following split-tier configuration:
- E-business (Application Tier) on RHEL5 32bit
- Oracle 9i (Database Tier) on RHEL4 64bit since it is not supported on RHEL5

I would appreciate any input.


Posted by Sam on August 06, 2008 at 05:37 AM PDT #

Hi, Sam,

Yes, this is supported. This is what's called a "split configuration" for Oracle E-Business Suite Release 11i, where the app tier is on a fully supported platform (like 32-bit RHEL 5), and the db tier is on a db-tier only platform (like 64-bit RHEL 4).


Posted by Steven Chan on August 07, 2008 at 06:26 AM PDT #

Hi Steven,

i have been looking around to find out the expected support end date for OEL4. can you please help me on this ?

Michael Sesuraj.

Posted by Michael Sesuraj on January 13, 2009 at 12:09 PM PST #

Hi, Michael:

Oracle's Support windows are listed here:


OEL's support is listed in the "Lifetime Support Policy: Oracle Technology Products" PDF. I just checked this. It shows different OEL support tables for Premier, Basic, and Network support.

I'm not an OEL specialist and I confess that I don't really know what the differences are between each of these support categories. I'd recommend looking up the table for your particular support class; if you need more details, a formal Service Request via Metalink might be your best bet.

I'm trying a clone migration from RHEL 4.3 to RHEL 5.2. Its a 2-tier set-up. I have applied all the required RPM's (I hope) on both tirers.

The DB tier is now up and running fine, but I'm having huge problems getting Discoverer running on the Apps Tier. There are plenty hits on Google with this problem - but no real solution. (We are running eBS on Oracle

Lots of info about LD_ASSUME_KERNEL settings, but that is all not relevant any more for RHEL 5.

I have an SR open with ML - but no solution yet.

Any suggestions?


Posted by Grant Cohn on February 09, 2009 at 03:10 PM PST #

Hello, Grant,

No suggestions based upon the information you've provided. There are no known issues with Discoverer, EBS, and RHEL. If you drop me a line with your SR number, I can take a quick look at this.


Posted by Steven Chan on February 10, 2009 at 05:04 AM PST #

Hello Steven Chan,

I am running eBS with db on HP-UX PARISC, application on one node and db on the other node.

1. Is it possible to clone the apps (node) from HP-UX PARISC to Linux RHEL 5 ?
2. Must i upgrade the database from to 10R2 for question 1 to be successful ?
3. Kindly direct me to links that can be of help for a successful migration of eBS apps from HP-UX PARISC to Linux RHEL 5

Thank you.

I have an eBS environment split tier environment where the app server requires more than 16GB of RAM that is supported by RHEL 5 -32bit. Can the eBS run on the RHEL 64bit OS? Is this supported? If not, what are my options.

Posted by Eric Espeseth on March 25, 2009 at 05:39 AM PDT #

Hi, Eric,

Unfortunately, EBS 11i application tier servers are not supported on Linux-x86 64-bit platforms.

The easiest option would be to implement a multi-node load-balanced architecture in your EBS environment. This would spread your application tier server load between multiple servers, which should reduce your memory requirements. For details about multinode deployments, see:

In-Depth: Load-Balancing E-Business Suite Environments - http://blogs.oracle.com/stevenChan/2006/06/indepth_loadbalancing_ebusines.html

Another option would be to consider upgrading to EBS R12. This is a different kettle of fish, of course, but I wanted to make sure that you're aware of this option. EBS 12.0 and higher are certified for Linux x86-64, for Oracle Enterprise Linux 4 and 4, Red Hat Enterprise Linux 4 and 5.

I have a 11.5.10CU2 env installed on OEL4. Can I upgrade to OEL5 in place? If so, is there a ML note describing the steps required?


Posted by Mark Waldron on May 18, 2009 at 01:35 AM PDT #

Hello, Mark,

I'm not a platforms specialist, but my understanding is that Note 316806.1 contains steps on how to do in-place upgrades like this.

If that Note doesn't fit the bill, it might be worth logging a formal Service Request via Metalink to get one of our platform specialists engaged.

Good luck with your upgrade!


Posted by Steven Chan on May 20, 2009 at 03:36 AM PDT #

Hello Steven,

I have done many, many Oracle EBS clones. This is the forst time I am trying to clone from Red Hat Linux 4 to Red Hat Linux 5. Thought I followed all the right docs but alas, I have hit a snag. The details have been documented in SR 3-5890925101:
Cloning EBS fails on appsTier with Java Error.

There is a certain amount of urgency to resolve this issue. Any help, advice and/or recommendations you have to offer would be most appreciated.

Thanks so much for your time,

Posted by Elaine Friedman on June 28, 2012 at 07:52 AM PDT #

Hello, Elaine,

I'm sorry to hear that you've encountered an issue with this.

I'll make sure that the Support Engineer assigned to your Service Request understands the urgency, but I would recommend that you explicitly ask Support to escalate your SR. You can do this by contacting Support and asking to speak with the on-duty Escalation Manager.

I'm trying to understand the difference between QU and CU. The reason I'm asking you this is because on the media pack download (ondemand) I can see "E-Business Suite Certified Configuration Release 11.5.10 QU 3.0 Media Pack for Linux x86" parts from B30942-01 to B30949-01. However, it doesnt mention if CU is included on not. I'm sorry for those dummy questions but I'm new on EBS world and trying to move from regular DBA to appl DBA. Also, I'd like to know if there is any documentation that explains all those version, releases and patches in the EBS world. Thank you in advance. Renato.

The "On Demand" downloads on the Software Delivery Cloud site are intended only for customers contracting services via our On Demand organization.

If you're interested in learning about the E-Business Suite, your best bet would be to download the E-Business Suite 12.1.3 images here:

Oracle VM Templates Available for E-Business Suite 12.1.3

These are virtualized images of prebuilt EBS 12.1 servers, so you can simply drop them into an Oracle VM environment and be up and running immediately.

Congratulations on your decision to move your skills up to the Apps DBA level. This is a good starting point:



Posted by Steven Chan on August 28, 2013 at 12:08 PM PDT #

Steven, thank you very much for your update in such short timeframe.

The idea of leaning ebs from 11.5 version is to

1) how to install/clone/upgrade/update 11 version since there are many customer still running that version;
2) how to upgrade from 11 to 12, again many customer "out there" running 11 and willing to upgrade to 12 thus I'd be able to help them by knowing both versions.

To sum up, take 1 step back, learn 11 and its particularities then step ahead to the "current" version.

Please advice if that's a wrong "approach"

Thank you once again. Renato

Posted by Renato on August 29, 2013 at 07:25 AM PDT #


I wouldn't bother with EBS 11i at this point. R12 was released in 2007, so it is the best release to learn going forward.


Posted by Steven Chan on August 30, 2013 at 10:15 AM PDT #

Is E-Business certified with RHEL 6? 32 or 64 bit OS?

Posted by guest on January 21, 2015 at 09:09 PM PST #

EBS 11i is not certified with either 32 or 64-bit RHEL 6. The last Linux OS certified is 32-bit Oracle Linux/RHEL 5 - this information is in My Oracle Support Certifications' page and the Installation and Upgrade Notes (MOS Note 316806.1).
