During the Amsterdam stage of the Oracle Open World Tour, I had a great opportunity to interview John Wookey Senior Vice President, Applications Development at Oracle Corporation. John is very high up in one of the largest if not the largest application development shop based on Oracle technology in the world. As such, he represents the biggest customer of Oracle’s Tools division as well as one of the most important customers of the Application Servers and Database product development teams. He is ‘topdog’- to speak with Oracle terminology – a major consumer of Oracle’s dogfood.
During this interview, we focused on the technology that John’s teams currently use of will be using in the foreseeable future for development of the many modules of the Oracle E-Business Suite. This post will be a somewhat unstructured summary of a one hour long conversation that was very, very interesting. The more refined article is to appear in OGH Visie, the magazine of the Dutch Oracle User Group (OGH).
For me, some of John’s comments came as a bit of a surprise, especially his view on the future of Oracle Forms within the Applications Development team. It sheds some more light on the issues we discussed just a few days ago. See also this post.
John explained how within the Apps division, there is a strong drive towards a Single Technology Stack Architecture for all Modules of the E-Business Suite. There is an Applications Technology group, headed by Cliff Godwin, that continuously investigates – along with the product development groups within Oracle, Tools, Application Server and Database – in new technological developments. Plans from the product development teams are discussed with this AppTech group in early stages, suggestions for desirable new features are made by this group. When new (Beta) releases become available, the AppTech group will test and pilot them and after careful consideration may decide to start applying them in the Apps product.
The early involvement of Apps in the development cycle and its focus on productivity and stability are an important quality boost for the overall process. Another area where Apps have vested interests is in porting the technology stack to different platforms. Apps has developed thousands of regression tests on tools and database and these are run automatically for new (alpha drops and beta) versions of the software, allowing product development very timely feedback on their work. Many of these regression test sets have been fed back into the Technology Development groups by Apps.
The AppTech group always needs to strike a balance between the minimum release of especially the database they can force upon their customers and the set of functionality available for the AppsDevelopers. Apps cannot force their customers to always upgrade to the latest database release, so they cannot afford to make use of the latest database features. Currently Apps certifies on 8.1.7, 9iR2 and 10g. Support for 8.1.7 will not last much longer, which means that developers within the Apps group can start using all of 9iR2 – which means compared to 8.1.7 that they have much more functionality at their disposal.
The Application Technology Group is also responsible for developing a common foundation for all Oracle Apps. This entails generic infrastructure components and libraries with reusable objects that can be used Apps-wide. I take it this also includes utilities and generators that make life easier – and more productive – for developers. It probably also includes management of Standards & Guidelines for doing development in the best or at least agreed-upon way.
John pointed out that within Oracle Apps, over the last few years many pieces of generic functionality were developed that not only enhanced the E-Business Suite, but should probably also be part of the development tools themselves. And much of their work has indeed been rolled forward into the tools. He mentioned three areas of generic Apps infrastructure that are currently not part of the development tools as we get them from Oracle, but could certainly be of interest to many more development shops than just Oracle Apps:
- Functional Security Architecture
- Menuing System
- Flex Fields
Later in the talk, John also spoke about a â€˜personalization frameworkâ€™ that I take to pertain specifically to the Self Service Technology Stack. That seems like a piece of generic functionality also desirable to external parties.
I asked John whether there is a chance Apps would share its own productivity enhancing frameworks and its no doubt huge piles of Standards and Guidelines with the rest of the world (starting with me).

[…] One of the keynote speakers during last week’s Oracle Open World Conference van John Wookey, Senior Vice President for Oracle Applications. John is sort of an old acquaintance, as two years ago I did an interview with him on dogfood (see: Eating your own dogfood – use of Oracle Development tools within the Oracle Applications development group ). Note: at that time, PeopleSoft, JD Edwards, Siebel and Retek were all competitors, no mergers on the horizon – or so I thought. And we discussed technology, of which I thought Wookey knew surprisingly much!This keynote was a different story altogether. In front of a close to 10.000 person audience, aided by two roaring Italian motor-engines ("they are from Ducati, one of our customers, an Italian motor-cycle constructor; we also would have liked to invite Boeing…"), John spoke strategy. Strategy for Oracle Applications, not just the E-Business Suite, or Fusion Apps, but all product lines. And as the buses in San Francisco cried out all over the city: Unlimited Applications. I was at first, I’ll freely admit, a little skeptical about Unlimited Applications – Oracle’s promise to provide unlimited support for all product lines – EBS, Siebel, Retek, JD Edwards, and PeopleSoft. However, I know not only believe they will actually do this, I can even see the sense of it.Oracle announced Oracle E-Business Suite R12 – and indicated that there will be an R13 further down the road. It also announced a new release of JD Edwards World (A9.1) on IBM I-series – the first new release of JDE since 1998 on that platform! Wookey also outlines the roadmap for Siebel – R8.0, 8.1 , 8.2 – and PeopleSoft – EE9, 9.1, 9.x. […]
[…] Last week, my colleague Marcos guided us through the still relatively new Oracle offering called XML Publisher. During a session of our Knowledge Center on Oracle Development Tools, we saw XML Publisher in action and used it ourselves. We also had quite a bit of discussion, whether XML Publisher will replace Oracle Reports and to what extent it may be used with Java/J2EE powered projects. We concluded that functionality wise XML Publisher is ready to take over from Oracle Reports. However, the current licensing policy as we understand it is rather prohibitive – $40K per processor, $30k if you’ve already licensed Application Server – or $40 per employee (not end user) which, depending on the actual conditions, could prove interesting.XML Publisher first came to my attention during Oracle World, Fall 2004. I wrote about it in the article Eating your own dogfood – use of Oracle Development tools within the Oracle Applications development group – Reporting: birth of a new tool: XML Publisher, an interview with John Wookey during Oracle World 2004 in Amsterdam. It is created initially to facilitate all those customers of the Oracle E-Business Suite that require reports based on data within the Oracle E-Business Suite and with customized layout. Oracle was facing more and more customers using the standard shipped reports and requiring specialized layout for those reports, often because of local regulations. Oracle realized it would not be possible to ship all those customized layouts as part of the core product, so XML Publisher was developed to allow customers to create their own report layouts based on standard (or even custom) data sources. The initial intention was to use all the curent reports in the E-Business Suite as Data Sources – RDFs ran with XML as output format – for the newly developed XML Publisher templates. It now seems that Oracle has a RDF2RTF processor – a tool that takes Oracle Report Definitions and converts them to XML Publisher style templates. However, this tool is not yet available external to Oracle, although that does seem to be the plan.More details on XML Publisher can be found among other resources in this article by Mark Rittman: A First Look At XML Publisher , More on XML Publisher and Wrapping up on XML Publisher . XML Publisher can be downloaded from Oracle MetaLink. Report-templates for XML Publisher are in fact RTF documents that are created using a Word plug-in. (According to Mark, there will be a plugin for Excel shortly. ) You can create the layout of the report using the full power of MS Word – quite handy compared to Oracle Reports Builder and much more convenient for end users. Including images, tables, indexes and other more interesting layout options is as effortless as with normal documents.The plugin part is used when the dynamic data elements are introduced into the template. Marcos demonstrated how you can first link the current template to an XML Data Source – which can be an XML Document on the file system or the internet or an SQL Query (also see More on XML Publisher). In the template itself, we can include elements from that XML source (internally specified through XPath expressions that we can though not need to edit), just by picking them in a wizard. We have the full range of XPath/XSLT expressions at our disposal, allowing us to manipulate the contents from the XML source before displaying it in the report. Note that here we will lose the end user and require a real developer or someone trained for day-to-day administration of the application. Marcos demonstrated how simple it is to create iterations – loops over sets of records that are typically displayed in tables or bullet lists in the report output. He also showed us how references to images can be dynamic: that this the URL for the image can be constructed while generating the report output from the values found in the XML source.We can preview the Report from the template at any time; the preview is available in PDF, HTML and Excel format. The data in the preview is the data from the XML Data Source we have attached to our template editing session.The XML Publisher plugin allows us to export the template definition in several formats, including XSL-FO and XSLT. The latter is an XSLT stylesheet that contains an awful lot of XSL-FO elements, embedded in an XSLT stylesheet. Taking this stylesheet, we can take an XML source and transform it to XSL-FO output – using any XSLT transformation engine, like Apache Xalan, Saxon or Oracle XDK. The XSL-FO document can be edited in one of several XSL-FO editors or rendered – more likely – using render engines like Apache FOP, to output formats like PDF, PS, SVG or RTF. Of course these functions are normally exectued by the XML Publisher Server, but it can be interesting to use the XSL-T created with the XML Publisher plugin for Word in more customized ways. Note that Report definitions are stored by the XML Publisher plugin as an XDO file along with an RTF document. This XDO file is a custom XML format, that describes the XML Data Source to be used when the report is executed.XML Publisher is based primarily on XML, XSL-FO (FO= Formatting Objects) and XSL-T (T=Transformations). It can render output in various formats, including HTML, PDF, RTF (Rich Text Format) and Excel (although currently the Excel output is basically just HTML output interpreted by Excel). The approach taken with XML Publisher as demonstrated by Marcos is very much like a PostScript/PDF Document Generator AMIS developed almost three years ago for one of our customers: we used HTML to define the Report template instead of RTF, had a less elegant way of injecting references to dynamic data elements and could not handle record sets. However, the basic approach using a template developed in Word by end-users, using a XSL-T stylesheet brimming with XSL-FO elements to transform XML datasets was there to, as was the rendering in PDF from XSL-FO. Well, in hindsight it sounds like the obvious approach, so of course there are many similarities.All in all, this session provided a very useful overview of where XML Publisher currently is, how it can be used and what the internals are. […]
Today I heard that John Wookey now has overall lead for all of Oracle Apps. Mr. Ron Wohl, previously his boss, apparently is away on sabbatical leave. In hindsight, I have come close to the sun….

when will the next version of oracle apps be made available.. v11 has been out for some time.
Very interesting article… It’s amusing that Oracle have been stressing for years that
Forms will remain part of the development toolset in Apps.. I guess it boils down to there
not being a viable alternative until ADF and JSF.
I’ve been using ADF/UIX on and off since it first came out and it’s interesting to see
it being used in anger now. If it’s implemented well and allows for Pluggable L&F then
it really will allow clients to develope a corporate look and feel throughout their ERP
and Back Office as well as using Portal etc….
If this doesn’t occur, then Oracle will lose out signifcantly to Axapta, where integration
with the desktop will be seamless (aparently)
What will really blow the doors off proper Apps customisation and integration is when
OC4j becomes the host for the applications tier… Bring it on!
We can but hope that Oracle SCM will come back in some form one day. At the moment, things don’t look good. Two of the three pro-OSCM Oracle employees you mention are no longer with the company, and the remaining members of the Oracle SCM team are focussed on internal Apps support only. The existing version of Oracle SCM is still fully supported, of course.
The day that new development on Oracle SCM stopped coincided with Microsoft’s announcement about their new “Team System” replacement for Visual SourceSafe. I’m pretty sure it was a coincidence, but it served to highlight that development lifecycle support is still a really important competetive area. I thought that future releases of Oracle SCM would be the basis of a strong Oracle offering in this area (some of the stuff that was being developed internally was very cool: integrated bug tracking, task tracking and version control). Oracle SCM also had a great selling point that you mention: it’s used by Oracle to version control the huge amount of code that comprises the Oracle database.
There are a number of fundamental architecture issues with Oracle SCM 6i/9i that were, for the most part, resolved in the “7.x” releases that we use internally. IMHO, part of the problem with Oracle SCM was a failure to release a “7.x” version externally. For a long time, the team were focussed on providing a hosted version control solution (a bit like SourceCast) that never really took off. In the meantime, a lot of customers started using 6i/9i and because most of the development effort was on “7.x”, customers were not seeing a lot of improvement in the 6i/9i code base.
It seems that now, the strategy is to support existing Oracle SCM customers fully, but concentrate new functionality (in JDeveloper) around third party version control systems like CVS and Subversion. The rapid change in direction was a bit of a surprise to many (myself included: I was responsible for the Oracle SCM integration in JDeveloper, so it had a bit of an impact on my priorities).
See response from Steve Muench in his weblog…
Also interesting: an interview by Tim Anderson with Ted Farell (Architect and Director, Application Development Tools Division, Oracle Corporation). Ted Farell sais – among many other things -: “We do have solutions today. One of our consulting departments has built a product called JHeadStart, and that will allow you to draw a business flow diagram and it will generate a Java application for you. ”
What he says about the next release of JDeveloper (10gR2 I believe, due in November or so) is encouraging:
Brian: if Oracle SCM (or at least an enhanced version of it) is used by such critical and humongous environments such as Oracle ST and Oracle Apps, would not such a product be a much sought after tool for the rest of the world? At some point I believe msrs. Fisher, Bradshaw and Thomas were ready to take on the world (primarily ClearCase) for doing SCM at the Enterprise Level. Do you what happened? Is there any chance of a ‘return with a vengeance’ of SCM at Oracle?
Excellent and insightful article. From our point of view (in tools development), Applications are indeed our biggest customers.
I know a little about the way that Apps and ServerTech (development tools now come under servertech too) organize version control. Most of ServerTech is now using a tool called ADE. This is a front end interface to version control which originally used a ClearCase back end. These days, most products in the ServerTech division are using ADE with an Oracle SCM back end.
Likewise, Applications have a frontend SCM interface called Arcs. They’re in a process of migration between the existing back end for Arcs and using Oracle SCM too.
The big, obvious benefit of both Arcs and ADE is that you can replace the back end SCM system without having a major impact on your developers.
Finally, it’s worth mentioning that Oracle SCM has effectively reached the end of the line in terms of new feature development. The version of Oracle SCM we use internally (much improved from OSCM 6i/9i) will likely never be released as an external product. Much of the development of Oracle SCM in the UK has been wound up. The remaining members of the Oracle SCM team in the UK are now actually part of the Applications division, working directly on Arcs.
