Choice Hotels Reduces Time to Market with Oracle WebCenter

WebCenter Team - Wed, 2014-04-16 07:00
Choice Hotels is a global hotel franchise with 6000+ franchisees. Choice is in the process of completely re-building their distribution platform for the next generation.  They currently process and distribute over $6B worth of reservation activity to the franchisees of Choice Hotels. To continue to grow and support the strategic business initiatives of the company they needed to address the primary vehicle for delivering business to their customers.  Their current platform was an amalgam of 25 years of development on disparate systems that offered limited inter-operability and scalability.  A strategic decision was made to adopt the Oracle technology stack to build out this new platform.



 They introduced more self-service opportunities to their business to create greater empowerment and flexibility, thus reducing the dependency on IT to introduce new features to their production systems. They are using WebCenter Sites as their Web Experience Management platform deployed for their International Websites. Standardizing on WebCenter Sites has allowed them to consolidate four different Content Management System platforms and created a Content Center of Excellence making it easier for any of their business users to take advantage of the WYSIWYG interface.

Perhaps the biggest win at the enterprise level is standardizing on the Oracle platform. They have seen tremendous benefits by being standardized on a focused set of tools and applications.  Their development, testing, administration, and database engineers now have greater flexibility and mobility throughout their enterprise.  Since they all have the same relative skill set, they can flex on certain projects in order to get them to market quicker.  No more Sys Admins having to learn the ins and outs of a particular system and its idiosyncrasies because everything is now a standard Oracle deployment.

An introduction into Oracle VM (V3.x)

Marco Gralike - Wed, 2014-04-16 06:00
One other internal presentation that was presented by me, showed the technical architecture and production experiences regarding Oracle VM V3. It was based on demo of a Hands-On Lab (HOL-9870, Oracle VM) given during Oracle Openworld 2013. Based on this HOL, structures were explained and demoed for architects and database administrators.

Read Oracle Linux 7 Beta 1

Surachart Opun - Wed, 2014-04-16 03:53
It might be too late posting about Oracle Linux 7 (Beta 1). Just came back from long holidays in Thailand. I think it's very interesting to learn something new in OL7. Users can download it by using OTN account.
Download.

Interacting client-side JavaScript with server-side PeopleCode

Duncan Davies - Wed, 2014-04-16 03:23

This week we have a guest-post from Richard Yip. Richard is a PeopleSoft HCM & Payroll Technical Consultant at Santander Bank here in the UK. He is a long-term PeopleSoft techie and a regular at the UKOUG conferences.  I’m delighted to be able to give him a conduit through which to share some of his good work.

Richard Yip: How to interact client-side Javascript with server-side PeopleCode

(using getElementById.focus(), getElementById.submit(), submitAction_win0(this.form,this.name) and window.showModalDialog)

This example shows a custom built payroll results calendar which allows the user to display multiple sets of payroll results information on a single page, without needing to navigate out of the page as is currently delivered.

Additionally, it allows the display of related information such as payslip and 12 Months Fiscal Summary (pivoted summary results).

Note: results have been “desensitized” .

Something that looks like this:

Example 1
Click for bigger

The App Designer page, PeopleCode, SQL, JavaScript, CSS and HTML are shown below. The HTML/CSS were initially prototyped using Microsoft Office SharePoint Designer.

Screen shots

Main page after selecting an employee from a search page. Example 2

 

The menu bar above is created by HTML.RY_GP_RSLT_CAL_PIVOT_SQL_HDR

The following codes are used: -

PeopleCode :
DERIVED_RY_GP10.HTMLAREA2.RowInit
SQL:   HTML.RY_GP_RSLT_CAL_PIVOT_SQL
HTML:  HTML.RY_GP_RSLT_CAL_PIVOT_SQL_HDR
HTML:  HTML.RY_GP_RSLT_CAL_PIVOT_SQL_DTL

Displaying the results calendar

When ‘Show Calendar’ is clicked, the payroll results for this calendar are now visible. See function Show_Calendar() and Hide_Calendar() in Javascript collection in HTML.RY_GP_RSLT_CUSTOM_JS.

Example 3
Click for bigger

Displaying the payroll results information

When then user clicks on any Calendar ID, highlighted in red, the PeopleCode is invoked via client side JavaScript.

To invoke PeopleCode, I used the javascript DOM method – see function do_calid(obj) in GetHTMLText(HTML.RY_GP_RSLT_CUSTOM_JS)

document.getElementById("DERIVED_RY_GP10_DETAIL_BUTTON").focus();
document.getElementById("DERIVED_RY_GP10_DETAIL_BUTTON").click();

Screen shot below show 3 different calendar group/calendar id clicked by the user using the results calendar above.

Example 4
Click for bigger

The Clear Data  button will remove the specific payroll result. Basically, each calendar results in contained in a <DIV> tag with an ID. The following line takes the id of the <div> tag, for example BOX1 and passes it to the field DERIVED_RY_GP10.ID_LBL and then automatically clicks the field DERIVED_RY_GP10_CLEAR_BUTTON. This is similar to the DOM click() function previously mention. See HTML.RY_GP_RSLT_SEG_HDR

<div id='%Bind(:12)' class="result_container">
<input class='calendar_container' id="DERIVED_RY_GP10_CLEAR_BUTTON" title="ID" style="WIDTH: 72px" onclick="this.form.DERIVED_RY_GP10_ID_LBL.value='%Bind(:12)';submitAction_win0(this.form,this.name);" type="button" value="Clear Data" name="DERIVED_RY_GP10_CLEAR_BUTTON">

The Copy to Excel  button will download the information to Excel. This uses the ActiveXObject(“Excel.Application”) function. See HTML.RY_GP_RSLT_HDR

Display the 12 Months Fiscal Summary

Using the window.showModalDialog function to display the 12 Months Fiscal Summary. See Get_Summary() in RY_GP_RSLT_CUSTOM_JS . Also see Get_Payslip().
Other method may include <iframe>

Example 5
Click for bigger

Summary/Design consideration

Strong knowledge of html, Javascript, CSS and  SQL in addition to PeopleCode.

Using a HTML editor facilitates prototype stage.

In this example, it’s all about presentation as getting the data from the database via SQL is fairly easier.

I have used the SQL XMLElement function to inject some html, albeit with a bit of trickery.

Page Field Name and Enable as Page Anchor gives the developer control over how the field is referenced in html

Preview of Maria Colgan, and Andrew Bond/Stewart Bryson Sessions at RM BI Forum 2014

Rittman Mead Consulting - Wed, 2014-04-16 02:11

We’ve got a great selection of presentations at the two upcoming Rittman Mead BI Forum 2014 events in Brighton and Atlanta, including sessions on Endeca, TimesTen, OBIEE (of course), ODI, GoldenGate, Essbase and Big Data (full timetable for both events here). Two of the sessions I’m particularly looking forward to though are ones by Maria Colgan, product manager for the new In-Memory Option for Oracle Database, and another by Andrew Bond and Stewart Bryson, on an update to Oracle’s reference architecture for Data Warehousing and Information Management.

The In-Memory Option for Oracle Database was of course the big news item from last year’s Oracle Openworld, promising to bring in-memory analytics and column-storage to the Oracle Database. Maria is of course well known to the Oracle BI and Data Warehousing community through her work with the Oracle Database Cost-Based Optimizer, so we’re particular glad to have her at the Atlanta BI Forum 2014 to talk about what’s coming with this new feature. I asked Maria to jot down a few worlds for the blog on what she’ll be covering, so over to Maria:


NewImage“Given this announcement and the performance improvements promised by this new functionality is it still necessary to create a separate access and performance layer in your data warehouse environment or to run  your Oracle data warehouse  on an Exadata environment?“At Oracle Open World last year, Oracle announced the upcoming availability of the Oracle Database In-Memory option, a solution for accelerating database-driven business decision-making to real-time. Unlike specialized In-Memory Database approaches that are restricted to particular workloads or applications, Oracle Database 12c leverages a new in-memory column store format to speed up analytic workloads.

This session explains in detail how Oracle Database In-Memory works and will demonstrate just how much performance improvements you can expect. We will also discuss how it integrates into the existing Oracle Data Warehousing Architecture and with an Exadata environment.”

The other session I’m particularly looking forward to is one being delivered jointly by Andrew Bond, who heads-up Enterprise Architecture at Oracle and was responsible along with Doug Cackett for the various data warehousing, information management and big data reference architectures we’ve covered on the blog over the past few years, including the first update to include “big data” a year or so ago.

NewImage

Back towards the start of this year, Stewart, myself and Jon Mead met up with Andrew and his team to work together on an update to this reference architecture, and Stewart carried on with the collaboration afterwards, bringing in some of our ideas around agile development, big data and data warehouse design into the final architecture. Stewart and Andrew will be previewing the updated reference architecture at the Brighton BI Forum event, and in the meantime, here’s a preview from Andrew:

“I’m very excited to be attending the event and unveiling Oracle’s latest iteration of the Information Management reference architecture. In this version we have focused on a pragmatic approach to “Analytics 3.0″ and in particular looked at bringing an agile methodology to break the IT / business barrier. We’ve also examined exploitation of in-memory technologies and the Hadoop ecosystem and guiding the plethora of new technology choices.

We’ve worked very closely with a number of key customers and partners on this version – most notably Rittman Mead and I’m delighted that Stewart and I will be able to co-present the architecture and receive immediate feedback from delegates.”

Full details of the event, running in Brighton on May 7-9th 2014 and Atlanta, May 15th-17th 2014, can be found on the Rittman Mead BI Forum 2014 homepage, and the agendas for the two days are on this blog post from earlier in the week.

The worst database developers in the world?

DBMS2 - Wed, 2014-04-16 00:45

If the makers of MMO RPGs (Massive Multi-Player Online Role-Playing Games) aren’t quite the worst database application developers in the world, they’re at least on the short list for consideration. The makers of Guild Wars didn’t even try to have decent database functionality. A decade later, when they introduced Guild Wars 2, the database-oriented functionality (auction house, real-money store, etc.) would crash for days at a time. Lord of the Rings Online evidently had multiple issues with database functionality. Now I’m playing Elder Scrolls Online, which on the whole is a great game, but which may have the most database screw-ups of all.

ESO has been live for less than 3 weeks, and in that time:

1. There’s been a major bug in which players’ “banks” shrank, losing items and so on. Days later, the data still hasn’t been recovered. After a patch, the problem if anything worsened.

2. Guild functionality has at times been taken down while the rest of the game functioned.

3. Those problems aside, bank and guild bank functionality are broken, via what might be considered performance bugs. Problems I repeatedly encounter include:

  • If you deposit a few items, the bank soon goes into a wait state where you can’t use it for a minute or more.
  • Similarly, when you try to access a guild — i.e. group — bank, you often find it in an unresponsive state.
  • If you make a series of updates a second apart, the game tells you you’re doing things too quickly, and insists that you slow down a lot.
  • Items that are supposed to “stack” appear in 2 or more stacks; i.e., a very simple kind of aggregation is failing. There are also several other related recurring errors, which I conjecture have the same underlying cause.

In general, it seems like that what should be a collection of database records is really just a list, parsed each time an update occurs, periodically flushed in its entirety to disk, with all the performance problems you’d expect from that kind of choice.

4. Even stupider are the in-game stores, where fictional items are sold for fictional money. They have an e-commerce interface that is literally 15+ years out of date — items are listed with VERY few filtering options, and there is no way to change the sort. But even that super-primitive interface doesn’t work; in particular, filter queries frequently return incorrect empty-set responses.

5. Much as in other games, over 10 minutes of state changes can be lost.

Except perhaps for #5, these are all functions that surely are only loosely coupled to the rest of the game. Hence the other difficulties of game scaling and performance should have no bearing on them. Hence there’s no excuse for doing such a terrible job of development on large portions of gameplay functionality.

Based on job listings, ESO developer Zenimax doesn’t see database functionality as a major area to fix. This makes me sad.

Coursera CEO Interview: Mike Caulfield nailed it two months ago

Michael Feldstein - Tue, 2014-04-15 20:03

Two months ago Mike Caulfield lamented the inability for many people in online education, especially massive online initiatives, to honestly learn from the past. In the post Mike referred to the failed AllLearn initiative and the seminal post-mortem written up in University Business.

How does that relate? A paragraph from the 2006 post-mortem of AllLearn really stuck out for me:

Oxford, Yale, and Stanford have kept quiet about the collapse of their joint e-learning venture…[h]owever, AllLearn’s closure could offer an unprecedented opportunity to step back and discuss the strengths and weaknesses of the business model… Further research into the series of collapsed online ventures may shed some light on what makes a successful distance education program, and enable some of the surviving online providers to redefine their business models and marketing strategies accordingly

Of course they don’t delve into these things honestly, and as a result most people in these institutions are unaware of them. Like Leonard, the institutions alter the record of the past. They wake up the next day with amnesia, consult a set of dramatically altered notes, and wonder why no one has tried massive Ivy League courses yet. The PR push to cover one’s tracks ends up erasing the institutional knowledge that could build a better initiative.

Little did Mike realize that he was writing a script.

One month later Coursera hired Richard Levin as its new CEO. As president of Yale, Levin was one of the key figures in the creation of All Learn in 2000, and after the 2006 collapse of the initiative Levin was one of the key figures directly responsible for the Open Yale Courses initiative.

The consensus view is that AllLearn failed to generate enough interest in its non-credit elite courses, and subsequently the program closed due to economics (by Levin’s own previous admission). In 2005 AllLearn attempted to address this challenge by branching beyond alumni as related in this Yale Daily News post [emphasis added in all quotes below].

“I think we’ve learned a lot form the experiment,” Levin said. “While I believe we’ve produced some very high quality courses, we’ve learned that it’s hard to generate large audiences sufficiently from these courses from just the alumni of the three partner schools. So we’ve reached out to attract broader audiences through affiliating with universities and through finding other organizations that might have an interest in making courses available to members.”

Fast forward a year, and it is clear that the effort had failed economically despite the broadening of audiences, again from the Yale Daily News.

Yale President Richard Levin, who served as AllLearn’s chairman, said he thinks that while the participating institutions learned what is necessary to manage a successful distance learning program, they were unable to make the project financially viable.

“We are disappointed that we weren’t able to find a way to make this successful economically,” Levin said. “[But] we learned a lot, and I think it will serve us well in the future.”

Open Yale Courses also provides non-credit elite courses. The problem? You might have guessed it, as described by this 2012 report for the Committee on Online Education.

Open Yale Courses has been supported by generous grants from the Hewlett Foundation, but those grants are ending this semester; and there is no provision yet for the continuation of this program. There has been extensive planning, however, to keep the 42 existing courses on the Yale site as well as the iTunes U and YouTube platforms. All of the courses are being stored and preserved for future study. New visitors are discovering Open Yale Courses daily and global media coverage, which has been constant and enthusiastic since the start of the project, continues unabated.

The initiative is now attempting direct solicitation as a method of funding.

I don’t mean to question Levin’s good intentions nor his considerable support of the mission of making education more accessible through online technology. However, I find it disingenuous to try and alter history. This week the New York Times interviewed Levin about his new role as Coursera CEO, and the reporter asked some good questions but lacked follow-up.

Q. Yale has not exactly been a mass institution.

A. No, but we were early in the on-line arena, with a venture back in 2000 called All-Learn.

Q. How much did you lose, and why didn’t that spoil this for you?

A. It was too early. Bandwidth wasn’t adequate to support the video. But we gained a lot of experience of how to create courses, and then we used it starting in 2007 to create very high quality videos, now supported by adequate bandwidth in many parts of the world, with the Open Yale courses. We’ve released over 40 of them, and they gained a wide audience.

So here we have yet another initiative offering non-credit elite courses, and one of the biggest challenges that Coursera faces is that it has yet to find a viable business model. The company is living on $85 million in venture capital investment and has not yet found revenue sources that go beyond a few million dollars per year (Signature Track). Levin called out this challenge in the same NYT interview.

Q. Doesn’t edX have an advantage in being not-for-profit, meaning they don’t have to worry about returning on investment so soon? Yesterday Andrew Ng said, “We’ve raised $85 million, so we’ve got some runway.” How much runway?

A. I think the principal investors in Coursera understand that this is a long term play. We’re fortunate to have patient investors; and as Andrew said, we’re quite adequately capitalized. I think we can become financially viable certainly within that five-year framework.

Q. You’re an economist. How do you get from here to there?

A. Right now courses are free and we’re charging for certification. We think that as the idea of using Coursera courses for professional advancement grows, the numbers seeking certificates will grow. And the price we charge probably can grow, too. A move from $50 or $60 for Signature Track to $100 is certainly imaginable. At $100 a pop, if you had two or three, or five million people. …

I would suggest that Coursera will not “get from here to there” by altering the record of the past. AllLearn failed to generate sufficient interest in its courses, and the proximate cause was not “insufficient bandwidth”. AllLearn in fact had several approaches that alleviated bandwidth concerns, including CD-ROM delivery and the ability to turn off high-bandwidth features. AllLearn’s average learner was a 47-year-old Yale alumni – hardly a case of low-income lack of access to sufficient bandwidth. Plenty of online ventures started in 2000 or prior have succeeded – Penn State’s World Campus, UMUC, most large for-profits, UMassOnline, University of Central Florida, etc. This was not a case of being “too early”.

Read the University Business post-mortem and the Yale article. The issue involved economics and insufficient revenue to offset expenses.

Coursera and all the xMOOC providers have this same long-term challenge of adequate business models. I called out this challenge as one of the four key barriers that MOOcs faced, based on a July 2012 post. I speak as someone who would like to see MOOCs succeed – not in their current form, but in a form that evolves to better meet learner needs. This healthy evolution won’t happen, however, unless the providers honestly evaluate the lessons of the past.

Update (4/17): It appears that Levin is doubling down on his new theory about AllLearn. From the Yale Daily News today:

“I knew from the beginning that [online ed] had great potential,” Levin said.

In fact, Yale’s experiment with online education began under Levin’s presidency. In 2000, Yale launched AllLearn, a joint venture with Stanford and Oxford that faltered after four years due to insufficient technology at the time. The Internet bandwidth in most homes was inadequate for properly sharing course material, Levin admitted.

For the record, I can find no explanations from the time of AllLearn’s demise in 2006 that insufficient bandwidth was the problem. What we do have are statements including from Levin himself that insufficient demand leading to unsustainable revenue was the problem.

Using test prep software to prepare for 12c OCP upgrade exam

Bobby Durrett's DBA Blog - Tue, 2014-04-15 17:54

I got the newly available Kaplan test prep software for the Oracle 12c OCP upgrade exam.

I took the test in certification mode when I was tired at the end of the day some day last week and got 44% right – fail!  I usually wait until I get all the questions right before taking the real test so I have a ways to go.

The practice test software has been useful  in terms of showing me things I didn’t study very well or at all.  I’m expecting to significantly improve my correct answer percentage on my next pass.

I’m a little nervous though because it seems that the real test involves some questions that are generic database questions and I don’t think that the test prep software includes that section.  If you look at the list of topics they have a  section called “Key DBA Skills”.  I’d hope that after 19 years as an Oracle DBA I’d have some skills, but there are plenty of things I don’t do every day, such as setting up ASM.  I guess I’ll just have to bone up on the key areas of pre-12c that I don’t use all the time and hope I’m not surprised.

Anyway, I’m at 44% but hoping to make some strides in the new few weeks.

April 2014 Critical Patch Update Released

Oracle Security Team - Tue, 2014-04-15 14:04

Hello, this is Eric Maurice again.

Oracle today released the April 2014 Critical Patch Update.  This Critical Patch Update provides fixes for 104 vulnerabilities across a number of product lines including: Oracle Database, Oracle Fusion Middleware, Oracle Hyperion, Oracle Supply Chain Product Suite, Oracle iLearning, Oracle PeopleSoft Enterprise, Oracle Siebel CRM, Oracle Java SE, Oracle and Sun Systems Products Suite, Oracle Linux and Virtualization, and Oracle MySQL.  A number of the vulnerabilities fixed in this Critical Patch Update have high CVSS Base Score and are being highlighted in this blog entry.  Oracle recommends this Critical Patch Update be applied as soon as possible.

Out of the 104 vulnerabilities fixed in the April 2014 Critical Patch Update, 2 were for the Oracle Database.  The most severe of these database vulnerabilities received a CVSS Base Score of 8.5 for the Windows platform to denote a full compromise of the targeted system, although a successful exploitation of this bug requires authentication by the malicious attacker.  On other platforms (e.g., Linux, Solaris), the CVSS Base Score is 6.0, because a successful compromise would be limited to the Database and not extend to the underlying Operating System.  Note that Oracle reports this kind of vulnerabilities with the ‘Partial+’ value for Confidentiality, Integrity, and Availability impact (Partial+ is used when the exploit affects a wide range of resources, e.g. all database tables).  Oracle makes a strict application of the CVSS 2.0 standard, and as a result, the Partial+ does not result in an inflated CVSS Base Score (CVSS only provides for ‘None,’ ‘Partial,’ or ‘Complete’ to report the impact of a bug).  This custom value is intended to call customers’ attention to the potential impact of the specific vulnerability and enable them to potentially manually increase this severity rating.  For more information about Oracle’s use of CVSS, see http://www.oracle.com/technetwork/topics/security/cvssscoringsystem-091884.html.

This Critical Patch Update also provides fixes for 20 Fusion Middleware vulnerabilities.  The highest CVSS Base Score for these Fusion Middleware vulnerabilities is 7.5.  This score affects one remotely exploitable without authentication vulnerability in Oracle WebLogic Server (CVE-2014-2470).  If successfully exploited, this vulnerability can result in a wide compromise of the targeted WebLogic Server (Partial+ rating for Confidentiality, Integrity, and Availability.  See previous discussion about the meaning of the ‘Partial+’ value reported by Oracle). 

Also included in this Critical Patch Update were fixes for 37 Java SE vulnerabilities.  4 of these Java SE vulnerabilities received a CVSS Base Score of 10.0.  29 of these 37 vulnerabilities affected client-only deployments, while 6 affected client and server deployments of Java SE.  Rounding up this count were one vulnerability affecting the Javadoc tool and one affecting unpack200.  As a reminder, desktop users, including home users, can leverage the Java Autoupdate or visit Java.com to ensure that they are running the most recent version of Java.  Java SE security fixes delivered through the Critical Patch Update program are cumulative.  In other words, running the most recent version of Java provides users with the protection resulting from all previously-released security fixes.   Oracle strongly recommends that Java users, particularly home users, keep up with Java releases and remove obsolete versions of Java SE, so as to protect themselves against malicious exploitation of Java vulnerabilities. 

This Critical Patch Update also included fixes for 5 vulnerabilities affecting Oracle Linux and Virtualization products suite.  The most severe of these vulnerabilities received a CVSS Base Score of 9.3, and this vulnerability (CVE-2013-6462) affects certain versions of Oracle Global Secure Desktop. 

Due to the relative severity of a number of the vulnerabilities fixed in this Critical Patch Update, Oracle strongly recommends that customers apply this Critical Patch Update as soon as possible.  In addition, as previously discussed, Oracle does not test unsupported products, releases and versions for the presence of vulnerabilities addressed by each Critical Patch Update.  However, it is often the case that earlier versions of affected releases are affected by vulnerabilities fixed in recent Critical Patch Updates.  As a result, it is highly desirable that organizations running unsupported versions, for which security fixes are no longer available under Oracle Premier Support, update their systems to a currently-supported release so as to fully benefit from Oracle’s ongoing security assurance effort.

Mark Hurd’s Latest Blog Explains Why Customer-Obsessed Marketing Is Your Next Competitive Edge



Oracle President Mark Hurd has posted his latest LinkedIn Influencer blog, “Customer-Obsessed Marketing Is Your Next Competitive Edge.” 
Mark HurdMark Hurd,
President, OracleIn this new blog, Mark writes, “Marketing executives are leading the charge to convince their organizations of the inherent danger in today’s highly digitized buyer-seller relationship. And they’re doing that by proving that “your customers are only one click away from your competitors” is more than just a clever phrase—it’s the difference between being a market leader and going out of business.
 
"The good news is that as marketing executives strive to develop new customer-engagement models, to optimize multiple channels formerly in conflict and generate new revenue streams, they now have access to world-class marketing-automation tools, which have the potential to keep more prospects from making that one-click jump to a competitor…

Frequently Misused Metrics in Oracle

Steve Karam - Tue, 2014-04-15 13:43
Lying Businessman

Back in March of last year I wrote an article on the five frequently misused metrics in Oracle: These Aren’t the Metrics You’re Looking For.

To sum up, my five picks for the most misused metrics were:

Business Graph

  1. db file scattered read – Scattered reads aren’t always full table scans, and they’re certainly not always bad.
  2. Parse to Execute Ratio – This is not a metric that shows how often you’re hard parsing, no matter how many times you may have read otherwise.
  3. Buffer Hit Ratio – I want to love this metric, I really do. But it’s an advisory one at best, horribly misleading at worst.
  4. CPU % – You license Oracle by CPU. You should probably make sure you’re making the most of your processing power, not trying to reduce it.
  5. Cost – No, not money. Optimizer cost. Oracle’s optimizer might be cost based, but you are not. Tune for time and resources, not Oracle’s own internal numbers.

Version after version, day after day, these don’t change much.

Anyways, I wanted to report to those who aren’t aware that I created a slideshow based on that blog for RMOUG 2014 (which I sadly was not able to attend at the last moment). Have a look and let me know what you think!

Metric Abuse: Frequently Misused Metrics in Oracle

Have you ever committed metric abuse? Gone on a performance tuning snipe hunt? Spent time tuning something that, in the end, didn’t even really have an impact? I’d love to hear your horror stories.

Also while you’re at it, have a look at the Sin of Band-Aids, and what temporary tuning fixes can do to a once stable environment.

And lastly, keep watching #datachat on Twitter and keep an eye out for an update from Confio on today’s #datachat on Performance Tuning with host Kyle Hailey!

Links to External Articles and Interviews

Michael Feldstein - Tue, 2014-04-15 11:41

Last week I was off the grid (not just lack of Internet but also lack of electricity), but thanks to publishing cycles I managed to stay artificially productive: two blog posts and one interview for an article.

Last week brought news of a new study on textbooks for college students, this time from a research arm of the  National Association of College Stores. The report, “Student Watch: Attitudes and Behaviors toward Course Materials, Fall 2013″, seems to throw some cold water on the idea of digital textbooks based on the press release summary [snip]

While there is some useful information in this survey, I fear that the press release is missing some important context. Namely, how can students prefer something that is not really available?

March 28, 2014 may well go down as the turning point where Big Data lost its placement as a silver bullet and came down to earth in a more productive manner. Triggered by a March 14 article in Science Magazine that identified “big data hubris” as one of the sources of the well-known failures of Google Flu Trends,[1] there were five significant articles in one day on the disillusionment with Big Data. [snip]

Does this mean Big Data is over and that education will move past this over-hyped concept? Perhaps Mike Caulfield from the Hapgood Blog stated it best, including adding the education perspective . . .

This is the fun one for me, as I finally have my youngest daughter’s interest (you made Buzzfeed!). Buzzfeed has added a new education beat focusing on the business of education.

The public debut last week of education technology company 2U, which partners with nonprofit and public universities to offer online degree programs, may have looked like a harbinger of IPO riches to come for companies that, like 2U, promise to disrupt the traditional education industry. At least that’s what the investors and founders of these companies want to believe. [snip]

“We live in a post-Facebook area where startups have this idea that they can design a good product and then just grow, grow, grow,” said Phil Hill, an education technology consultant and analyst. “That’s not how it actually works in education.”
