PDB Logging Clause… Again…

Tim Hall - 11 hours 3 min ago

About 14 months ago I spotted a problem with the PDB Logging Clause. I opened an SR and several months later I got a patch, which unfortunately didn’t fix the issue, just altered the symptom somewhat. I wrote about that patch here.

Yesterday I got a new patch, which actually does fix the problem, so now the PDB Logging Clause works as documented!

I’ve updated the PDB Logging Clause article to reflect the change.

I realise it’s a small issue, with an easy workaround, but 14 months seems a bit excessive. :)

Oracle Utilities Customer Care and Billing available

Anthony Shorten - 18 hours 53 min ago

Oracle Utilities Customer Care and Billing is now available. This release includes the newest version of Oracle Utilities Application Framework (V4.

This version of the Oracle Utilities Application Framework has the following features:

  • New Login Screen - A simpler login screen has been introduced with a new screen in line with Oracle's Cloud offerings.
  • Session Timeout - In past releases when a session expired due to inactivity it would throw the user back to the login screen. This release now includes a popup message informing the user that the session is timed out prior to sending the user back to the login screen.
  • Required Fields indicator - In line with the new interface implementation introduced in, required fields can be indicated with a required fields indicator: *. This only applies to newer UI hint based screens. For backward compatibility this feature can be disabled.
  • Menu Behavior - Menu behavior has been tweaked to allow greater flexibility and a wide range of device support. Menu's can be locked into position to cater for user behavior. 
  • Toolbar History enhancements - In Oracle Utilities Application Framework, identifiers were recorded when using individual functions to enhance navigation. To complement this, these identifiers will be displayed in the History on the toolbar.
  • Component Installation - In the past installation, required additional effort to install individual components such as channels or tiers in an installation event. This enhancement greatly simplifies this by assigning installation roles to individual installations. Upon selecting appropriate roles, only those parts of the installation are exposed and configured for that installation. It is also possible to change roles after installation for maximum flexibility. This enhancement allows disparte installations to be linked into a virtual environment and managed for patching and management from Oracle Enterprise Manager easily
  • New Help Engine - This releases sees the product use the Oracle Help Engine for Web which provides greater usability, flexibility and standardization for our help. This enhancement is only available to Oracle WebLogic customers. Customers on IBM WebSphere will continue to use the legacy help engine. This also means that Framework Help is now included in Product Help.
  • Enhanced OIM Integration - The Business object used for Oracle Identity Management (OIM) has been enhanced following feedback from the Oracle Cloud implementations and customers using OIM. The interface now defaults more attributes and uses the user templating functionality to reduce the amount of business rules within OIM.
  • User Security Changes - To support greater levels of security, the user object now has additional security levels to control different aspects of security ralated to its maintenance. For example, it is now possible to allow specific users to administrate user group membership.
  • Map XML Enhancements - A simpler approach to mapping fields has been implemented to speed up mapping XML data types including a new wizard to aid schema designers.
  • XQuery engine upgraded - The latest Oracle XQuery engine has been adopted to provide new functions and reduce memory footprint needed for scripting.
  • Batch Parameter Security - It is now possible to encrypt data used on individual sensitive batch parameters.
  • System Heath Check - A new system wide health check API has been introduced that can be extended to verify components within the architecture to provide status information. The initial release will cover architecture and specific level of service checks. A simple user interface and web service have been included for this facility. This will be incorporated into a future Application Management Pack for Oracle Utilities release.
  • Additional Sort keys on Manual To Dos - Manual To Do entries now populate the standard sort keys even if custom sort keys are populated.
  • Extendable Lookup Enhancements - We have added a few new features for Extendable lookups to make them easier to use. This includes characteristic support, a new CLOB field, overriding support, action support and extended validation support.
  • Support Manual Transition of Sych Requests - It is now possible to manually transition a Sync Request.
  • Currency Symbol Support - Number elements may define a currency reference to automatically render the currency symbol.
  • Extended Currency Support - The base classes within the framework have been extended to support a wider range of world currencies.
  • Page Based Web Services - Inbound Web Services has been extended to now support legacy page based services. This will reuse the definitions in the page services to expose them as Inbound Web Services without the need for further configuration. This will aid in moving from XAI to IWS for legacy customers.
  • Message Driven Bean in IWS - The MDB has now been moved to the IWS implementation to implement an Integration Server architecture. Existing MDB implementations will be supported in the short term but will need to move to this new IWS implementation long term.

More articles will be published over the next few weeks outlining more information about most of these enhancements. Refer to the product documentation and release notes for more details of each of these enhancements.

Notes on packaged applications (including SaaS)

DBMS2 - 20 hours 5 min ago

1. The rise of SAP (and later Siebel Systems) was greatly helped by Anderson Consulting, even before it was split off from the accounting firm and renamed as Accenture. My main contact in that group was Rob Kelley, but it’s possible that Brian Sommer was even more central to the industry-watching part of the operation. Brian is still around, and he just leveled a blast at the ERP* industry, which I encourage you to read. I agree with most of it.

*Enterprise Resource Planning

Brian’s argument, as I interpret it, boils down mainly to two points:

  • Big ERP companies selling big ERP systems are pathetically slow at adding new functionality. He’s right. My favorite example is the multi-decade slog to integrate useful analytics into operational apps.
  • The world of “Big Data” is fundamentally antithetical to the design of current-generation ERP systems. I think he’s right in that as well.

I’d add that SaaS (Software As A Service)/on-premises tensions aren’t helping incumbent vendors either.

But no article addresses all the subjects it ideally should, and I’d like to call out two omissions. First, what Brian said is in many cases applicable just to large and/or internet-first companies. Plenty of smaller, more traditional businesses could get by just fine with no more functionality than is in “Big ERP” today, if we stipulate that it should be:

  • Delivered via SaaS.
  • Much easier to adopt and use.

Second, even within the huge enterprise/huge app vendor world, it’s not entirely clear how integrated ERP supposedly is or isn’t with CRM (Customer Relationship Management). And a lot of what Brian talks about fits pretty cleanly into the CRM bucket.

2. In any case, there are many application areas that — again assuming that we’re in the large enterprise or large internet company world — fit well neither with classical ERP nor with its CRM sibling. For starters, investigative analytics doesn’t fit well into packaged application suites, for a myriad of reasons, the most basic of which are:

  • The whole point of investigative analytics is to discover things that are new. Therefore, business processes are inherently unpredictable.
  • So are data inputs.

If somebody does claim to be selling an app in investigative analytics, it is usually really an analytic application subsystem or else something very disconnected from other apps. Indeed, in almost all cases it’s both.

3. When it comes to customer-facing websites, I stand by my arguments three years ago in the post just linked above, which boil down to:

  • What I just said above about investigative analytics, plus the observation that …
  • … websites have a strong creative aspect that fits badly with soup-to-nuts packaged applications.

Also, complex websites are likely to rely on dynamic schemas, and packaged apps have trouble adapting to those.

4. This is actually an example of a more general point — packaged or SaaS apps generally assume rather fixed schemas. (The weasel word “rather” is included to allow for customization-through-configuration, but I think the overall point holds.) Indeed, database design is commonly the essence of packaged app technology.

5. However, those schemas do not have to be relational. It would be inaccurate to say that packaged apps always assume tabular data, because of examples such as:

  • SAP has built on top of quasi-objects for a long time, although the underpinnings are technically relational.
  • There are some cases of building entirely on an object-oriented or hierarchical data model, especially in health care.
  • Business has some inherent hierarchies that get reflected in data structures, e.g. in bills of materials or organization charts.

But even non-tabular data structures are, in the minds of app developers, usually assumed to have fixed schemas.

My Delphix presentation at Oaktable World

Bobby Durrett's DBA Blog - 20 hours 40 min ago

It is official.  I will be doing my Delphix presentation at Oaktable World during the Oracle OpenWorld conference at the end of this month.  My talk is at 9 am on Tuesday, October 27.

I will describe our journey as a new Delphix customer with its ups and downs. I tried to have the spirit of a user group talk where you get a real person’s experience that you might not get from a more sales oriented vendor presentation.

Kyle Hailey, a Oaktable member and Delphix employee, will host my talk.  I have been very impressed by Kyle’s technical knowledge and he will be with me to answer questions about Delphix that I could not answer.  I think it will be a good combination of my real world user experience and his depth of technical background in Delphix and Oracle performance tuning.

If you are going to OpenWorld and if you want to know more about Delphix come check it out.  Also, feel free to email me or post comments here if you have any questions about what the talk will cover.

Response to Robert Talbert: Pedagogical change is difficult, many need support

Michael Feldstein - Wed, 2015-10-07 12:51

By Phil HillMore Posts (367)

On Monday Robert Talbert, associate professor at Grand Valley State University and author of the Casting Out Nines blog, wrote a provocative and important post titled “Active learning as an ethical issue”. Robert noted:

The recent Proceedings of the National Academy of Sciences study stands out among these recent studies. It is a meta-study of 225 prior studies on active learning, and the results are bracing: students in these studies who were in classes focused on lecture and direct instruction in the classroom were 55% more likely to fail their courses than their counterparts in active learning focused classes, and scored almost half a standard deviation lower than their active learning counterparts on exams.

This sentence from the PNAS study stopped me in my tracks when I first read it:

“If the experiments analyzed here had been conducted as randomized controlled trials of medical interventions, they may have been stopped for benefit—meaning that enrolling patients in the control condition might be discontinued because the treatment being tested was clearly more beneficial.”

Robert’s central point is that active learning should be thought of as an ethical issue, where it could be considered unethical to withhold treatment. He then asks why faculty might withhold active learning and listed four reasons: self-preservation, laziness, a weird and irrational superiority complex, and legitimate external forces (such as overly controlling school structure).

The argument is an interesting and compelling one based on the study, and it is worth reading the whole article and his follow-up post. I wish we treated teaching and learning more often as an ethical issue,but I would add one additional reason that the active learning treatment is not more prevalent. This one comes from our discussions with faculty and support staff as part of our e-Literate TV series on personalized learning, and Michael and I summarized the point in the introduction episode. In a nutshell, changing to active learning (described as personalized learning in the series, but this terms overlaps with active learning in the context of this discussion) designs often or usually comes along with a fundamental change in role of the faculty and TAs involved. This changing role is profound and not easy, especially if faculty try to make changes on their own without peer or staff support.

Michael Feldstein: And going along with that was a willingness for faculty and for students to really ask some hard questions about the roles that they needed to take in the classroom, right? This is no longer, “I go up as a faculty member, and I lecture. I tell you what you know. And you, as a student, dutifully write it down and regurgitate it on the test.”

Faculty have to be comfortable letting go of a certain amount of control. We heard that over and over again. And students need to be comfortable and confident taking a certain amount of control over their education.
Faculty have to be comfortable letting go of a certain amount of control.

Phil Hill: Just taking a step back, I can’t emphasize enough what we’re talking about, the fact that this personalized learning, where it’s done in an appropriate manner, absolutely doesn’t replace the faculty. So, we just need to move past a lot of that part of the discussion.

But that change in role is significant. So, when you say, “You’ve got to give up some control,” we’re not just talking a slight adjustment in your teaching; you’re talking about something deeply held, internal beliefs. And part of the implication there is not just that it’s significantly different, but it also means it takes a lot of work and a lot of time to make that transition in a role.
It’s not just that it’s significantly different . . . , it also means it takes a lot of work and a lot of time.

And then, to pick up on your other point, students are coming in, and they need to be much more part of an active learning experience. Well, they’ve gone through, likely, the K–12 system, where they’ve almost been taught to be passive learners, or that’s sort of their expectations.

But now they’re coming in, and they’re being asked to do a lot of active work—to really stay up to speed, not put off work and cram right before the exams, but come in prepared to the classes. And a lot of times, they’re teaching themselves. So, those two change in roles are very significant, and they take time for people to deal with.

Michael also noted this challenge of knowing how to change in his recent post on lectures.

Following the IHE piece on Essex County College’s struggles to get good outcomes from their personalized learning program in developmental math, and following my blog post on the topic, Phil and I had an interesting exchange about the topic in email with ECC’s Vice President for Planning, Research, and Assessment Doug Walercz. With his permission, I’d like to share some of his observations with you. One of the big takeaways from the conversation, for me, is that our cultural notion of the pedagogical work that happens in a good lecture is pretty impoverished relative to the reality. We don’t have a clear understanding of all the things that a good lecture accomplishes, and therefore we often lose valuable elements of student support when we try to replace it. This has pretty serious implications for MOOCs, flipped classrooms, personalized learning, and a wide array of pedagogical approaches that replace a traditional in-person lecture with something else.

Michael then shared Doug’s email describing his viewpoints on expert blindness and the nature of combining non-cognitive aspects of teaching with content delivery. Michael concludes:

We don’t fully understand what we are doing well now. Therefore, when we attempt to deconstruct it and then reconstruct it in a different environment, we don’t really know what we will miss or how we will need to retrain our instructors so that we won’t miss it. That’s why it is so important to undertake these sorts of experiments thoughtfully, self-critically, and iteratively.

The point is that changing to any new pedagogy – active learning, adaptive, personalized, etc – changes the role of faculty and the methods of providing support to students in significant ways. I would add this difficulty with understanding and implementing change to Robert’s list of reasons why the active learning treatment has been withheld. Using Robert’s argument that this this an ethical issue, this reason should not be one to prevent such a change, but it is a reason why many faculty have not yet changed or a reason that additional support for faculty might be needed in order to allow more extensive adoption of active learning.

Some faculty will be able to make these changes to active learning on their own – think of them as autodidacts in learning about learning – but if you want deeper changes, then we need to acknowledge that many, if not most, faculty will need support to do so.

In Robert’s follow-up post, he makes an important point about assessment and effectiveness:

But also do this: Gather formative assessment data on a regular basis and see what students are actually learning.Don’t try to base the effectiveness of your teaching on how much passion and verve you appear to bring to lectures; don’t base it on summative assessments where the data come too late for students to act on them; don’t base it on how many students talk in your discussions or how bright and bushy tailed they appear to be. Base it on data that you collect about student learning.

Then do this: Analyze your assessment data when you get it, and objectively decide whether your teaching is helping students learn. And if it isn’t, consider how you might change, and then make the change.

Why go to Oracle OpenWorld?

Duncan Davies - Wed, 2015-10-07 07:00

We’re a shade under a month away from the biggest event in the calendar for those that work in the Oracle marketplace – the Oracle OpenWorld Conference.

It runs every year in San Francisco and draws a massive 60,000 attendees from 145 countries (plus 2.1 million online attendees). That’s huge.

There are more than 2,500 sessions from ~3,600 speakers, approximately half of which are customers/partners and half are Oracle themselves. As well as the sessions there are the demo grounds and the exhibition hall, all great places for networking with people that you’ve either not met before or have only ever come across online. You get quality face-time with top developers and execs, who are normally hidden behind many levels of Oracle Support. These are the people who have designed and written the products and services that we’ll be using over the coming years, so meeting up with them is priceless.

If you register before the event, it’s $2,450 (about £1,600).

I’m lucky to have the chance to go again this year, and I know already that it’s going to have huge value for both me and Cedar. Both my colleague, Graham, and I were lucky enough to be selected to speak (his session is on Fluid, mine is on Selective Adoption – the two hottest topics in PeopleSoft right now).

Graham also produced this lively promo video:

This (above) is what we look like, it’d be great to say hello to you if you’re around. Likewise, if you’re coming to either of our sessions let us know and we’ll be sure to say hi.

As a nice bonus, we get to see Elton John and Beck at the Appreciation Event!

I’m really looking forward to seeing and hearing about the very latest from the PeopleSoft and Fusion/Taleo worlds. Look out for a Cedar event when we return where we can share everything with you.
