OracleAS 10g Upgrade Paths

[May 9, 2007 Update:  Corrected legend typo from OCSM to OCMS.  "OCMS" represents Oracle Communication & Mobility Server.  Elaborated on certification stance to remind readers that although OracleAS 10g 10.1.3 is part of Release 12's techstack, it can't be upgraded in place right now.]

There are a lot of Oracle Application Server 10g releases.  I find it challenging to keep them straight myself, so I can only imagine how hard it must be for you to sort out upgrade paths between the various releases.  In response to popular demand at this year's Collaborate conference, here are my personal cheatsheet diagrams that I use to find upgrade paths between the various OracleAS 10g releases. 

A Hand-Drawn Map Through the Woods

A word of caution:  I've reviewed this information with our Oracle Application Server Release Managers, but these charts don't represent official documentation from Oracle Application Server Development.  In fact, I'm not sure that any single piece of official documentation captures this kind of information.  So, if there are any conflicts between what I show here and the official documentation, the latter prevails (and let me know, so I can fix my own diagrams).

Distinguishing Between the Two Major OracleAS 10g Releases

There are a couple of things you should bear in mind before reading these:

  1. The OracleAS 10g components used by the E-Business Suite -- Single Sign-On, Oracle Internet Directory, Discoverer, Business Intelligence, Portal, Web Cache, and Oracle Integration (including BPEL 10g) -- are released in the 10.1.2/10.1.4 codeline. 

  2. The OracleAS 10g 10.1.3.x codeline is the J2EE-only subset of OracleAS 10g.  These products are released on their own codeline and have a completely separate upgrade roadmap.  We don't certify any integrations between the E-Business Suite Release 11i and these products, although Release 12 includes 10.1.3 as its Java ORACLE_HOME.   I'm including my diagrams for this group, too, so you can see how the releases relate to each other.
How to Read the Diagrams

Here's a legend for reading the following diagrams:

Updated Legend:

If you haven't installed any OracleAS 10g releases before, you can start with any of the fresh install versions (marked with solid borders).  You can only apply incremental patchsets (marked with dashed borders) to an existing environment previously built with a fresh install version.

Releases Useful for E-Business Suite Integrations

The following chart shows upgrade paths between releases that are relevant to E-Business Suite sysadmins interested in using Oracle Application Server 10g components.  These components include Single Sign-On, Oracle Internet Directory, Discoverer, Business Intelligence, Portal, Web Cache, and Oracle Integration (including BPEL 10g and Business Activity Monitoring 10g).

Reading the chart, you can see that it's possible to upgrade from Oracle Application Server 10g to the Patchset.   Once you've done that, it's possible to install Portal on top of that upgraded environment.

A different path shows that it's possible to upgrade your OracleAS 10g environment to the Patchset. 

Likewise, if you've installed OracleAS 10g and upgraded that environment to use the latest Oracle Identity Management release (marked as "IM"), you can upgrade that environment, in turn, to the Patchset.

The "Other" OracleAS 10g Release

The diagram below is relevant for customers who are building their own J2EE applications using OracleAS 10g development tools, including Business Process Execution Language (BPEL), Business Activity Monitoring (BAM), Oracle Web Services Manager (OWSM), and Enterprise Service Bus (ESB).  With the exception of BPEL and BAM, E-Business Suite Release 11i users don't generally use any of the following releases, but I'm including this chart for the sake of completeness.  Release 12 includes OracleAS 10g 10.1.3 in its techstack but it can't be upgraded in place to a later version right now.

A Final Word about Version Numbers

For reasons too tortuous to go into here (and because I don't really understand them myself), Oracle Application Server version numbers don't necessarily correspond to the order in which a particular patchset was released.  They also don't mean that you can apply a higher version on top of an older version. 

For example, the Patchset was released after the Identity Management (IM) release.  Since they're on separate codelines, you can't apply the Identity Management release on top of the Patchset.  That's not a meaningful combination since they're different products entirely. 

When in Doubt, Contact Oracle Support

It is not without some misgivings that I post this information here.  As is usually the case when wading into this area, these charts and their accompanying examples might have helped some of you but confused others. 

Remember, I'm part of E-Business Suite Development, not Oracle Application Server Development.  In some ways, I'm a passerby in these parts, just like you.  So, if you do need more help in assessing the viability of a particular upgrade for your environment, it's advisable to go directly to the source:  Oracle Support is always your best option for getting a definitive answer to your questions.



A very timely and informative post given that I'm just in the process of an AS 10g upgrade specifically to get Discoverer 10g. One question I do have though, is around eBusiness and licensing. If you are an existing 11i customer with Discoverer 4i licenses, is the upgrade to Discoverer 10g covered by those licenses? Similarly 9iAS to 10G AS?

Posted by Gareth Roberts on May 07, 2007 at 12:11 PM PDT #

Gareth,My understanding is that if you've licenced an E-Business Suite product that includes Discoverer-based content (e.g. Financials Intelligence or anything in the Business Intelligence System), then this includes your Discoverer licence.  Your Discoverer licence includes free upgrades from 4i to 10g, since 4i is now desupported.So, the bottom line is that you can upgrade your E-Business Suite environment from Discoverer 4i to 10g at no additional cost.  Licencing for Oracle Application Server is a bit different, however.  Having a Oracle9i Application Server licence as part of Release 11i doesn't automatically grant a licence for Oracle Application Server 10g.  There may be some conditions where you're granted a restricted use licence for Oracle Application Server 10g.  Given that I'm in Development (and not privy to a lot of licencing-related updates), I'd recommend a quick chat with your Oracle account manager.  He or she can fill you in on the latest updates for restricted-use licences for Oracle Application Server 10g.Good luck with your upgrade!Regards,Steven

I've been told by our Oracle Account team that release of OAS Form (middle-tier) is impending (over a year now). This release is important to us because 1) we're moving to Vista and supposedly this .release is "Vista certified" with JRE not jinitiator; and 2) our Vendor Application is not certed on 11.
Can you shed any light on the G.A. of OAS Is it for real? Otherwise we are trying to get JRE 1.6 working in place of Jinitiator on OAS getting hung up no class def found for "Java Plug-in 1.6.0_03
load: class oracle.forms.engine.Main not found.
java.lang.ClassNotFoundException: oracle.forms.engine.Main

Obviously Oracle Support will not touch this, but Gallo has a very real business problem that we some how have to solve.
Thanks for listening.

Hello, Stephen,I haven't heard any firm details about the Forms release date that can be shared publicly at this point.  I've sent your email to the OracleAS Release Manager so that he's aware that this release is on Gallo's critical path.Regards,Steven

Hi, Stephen,A quick update from our OracleAS team: patchset is
already released on Windows and Solaris.  Linux x86, x86-64, Win x86-64 and a
couple of other platforms will be released shortly.Regards,Steven

Hi Stephen

We are currently using OAS 10.1.2. Any news about the 11g release as to when this would be available?


Posted by Venkat on August 13, 2008 at 12:15 AM PDT #

Hi, Venkat,

No, I'm afraid I don't have anything I can share about that release. I'll post more information about this as soon as I can.
