Google Glass + iBeacons

Oracle AppsLab - 1 hour 49 min ago

GlassBeacon

If you haven’t talk to me IRL for the past 10 months, then I haven’t pestered you about the wonders of BLE and micro-location. My love affair with BLE (Bluetooth Low Energy) beacons became clear when I heard at WWDC 2013 that Apple was implementing BLE beacon detection in their CoreLocation framework. Apple showed how a small BLE beacon sending a constant signal (UUID + Major + Minor *) at a given interval could help for what is now known as micro-location.

At the time I just happened to be experimenting with wifi and bluetooth RSSI to accomplish similar results. I was prototyping a device that sniffed MAC addresses from surrounding devices and trigger certain interactions based on our  enterprise software (CRM, HCM, etc). You can find more on this topic in the white paper “How the Internet of Things Will Change the User Experience Status Quo” (sorry but its not free) that I presented last year at the FiCloud conference.

The BLE beacon or iBeacon proved to be a better solution after all, given its user opt-in nature and low power consumption capabilities. Since then I have been prototyping different mobile apps using this technology. The latest of these is a Google Glass + iBeacon ( github link: GlassBeacon) example. I’m claiming to be the first to do this implementation since the ability to integrate BLE on Glass just became available on April 15 2014 :).

Stay tuned for more BLE beacon goodness. We will be showing more enterprise related use cases with this technology in the future.

*UUID: a unique id to distinguish your beacons. Major: used to group related sets of beacons. Minor: used to identify a beacon within a groupPossibly Related Posts:

Webcast: Database Cloning in Minutes using Oracle Enterprise Manager 12c Database as a Service Snap Clone

Pankaj Chandiramani - 8 hours 30 min ago

Since the demands
from the business for IT services is non-stop, creating copies of production
databases in order to develop, test and deploy new applications can be
labor intensive and time consuming. Users may also need to preserve private
copies of the database, so that they can go back to a point prior to when
a change was made in order to diagnose potential issues. Using Snap Clone,
users can create multiple snapshots of the database and “time
travel
” across these snapshots to access data from any point
in time.


Join us for an in-depth
technical webcast and learn how Oracle Cloud Management Pack for Oracle
Database's capability called Snap Clone, can fundamentally improve the
efficiency and agility of administrators and QA Engineers while saving
CAPEX on storage. Benefits include:



  • Agile provisioning
    (~ 2 minutes to provision a 1 TB database)

  • Over 90% storage
    savings

  • Reduced administrative
    overhead from integrated lifecycle management

MongoDB is growing up

Curt Monash - 9 hours 37 min ago

I caught up with my clients at MongoDB to discuss the recent MongoDB 2.6, along with some new statements of direction. The biggest takeaway is that the MongoDB product, along with the associated MMS (MongoDB Management Service), is growing up. Aspects include:

  • An actual automation and management user interface, as opposed to the current management style, which is almost entirely via scripts (except for the monitoring UI).
    • That’s scheduled for public beta in May, and general availability later this year.
    • It will include some kind of integrated provisioning with VMware, OpenStack, et al.
    • One goal is to let you apply database changes, software upgrades, etc. without taking the cluster down.
  • A reasonable backup strategy.
    • A snapshot copy is made of the database.
    • A copy of the log is streamed somewhere.
    • Periodically — the default seems to be 6 hours — the log is applied to create a new current snapshot.
    • For point-in-time recovery, you take the last snapshot prior to the point, and roll forward to the desired point.
  • A reasonable locking strategy!
    • Document-level locking is all-but-promised for MongoDB 2.8.
    • That means what it sounds like. (I mention this because sometimes an XML database winds up being one big document, which leads to confusing conversations about what’s going on.)
  • Security. My eyes glaze over at the details, but several major buzzwords have been checked off.
  • A general code rewrite to allow for (more) rapid addition of future features.

Of course, when a DBMS vendor rewrites its code, that’s a multi-year process. (I think of it at Oracle as spanning 6 years and 2 main-number releases.) With that caveat, the MongoDB rewrite story is something like:

  • Updating has been reworked. Most of the benefits are coming later.
  • Query optimization and execution have been reworked. Most of the benefits are coming later, except that …
  • … you can now directly filter on multiple indexes in one query; previously you could only simulate doing that by pre-building a compound index.
  • One of those future benefits is more index types, for example R-trees or inverted lists.
  • Concurrency improvements are down the road.
  • So are rewrites of the storage layer, including the introduction of compression.

Also, you can now straightforwardly transform data in a MongoDB database and write it into new datasets, something that evidently wasn’t easy to do before.

One thing that MongoDB is not doing is offer any ODBC/JDBC or other SQL interfaces. Rather, there’s some other API — I don’t know the details — whereby business intelligence tools or other systems can extract views, and a few BI vendors evidently are doing just that. In particular, MicroStrategy and QlikView were named, as well as a couple of open source usual-suspects.

As of 2.6, MongoDB seems to have a basic integrated text search capability — which however does not rise to the search functionality level that was in Oracle 7.3.2. In particular:

  • 15 Western languages are supported with stopwords, tokenization, etc.
  • Search predicates can be mixed into MongoDB queries.
  • The search language isn’t very rich; for example, it lacks WHERE NEAR semantics.
  • You can’t tweak the lexicon yourself.

And finally, some business and pricing notes:

  • Two big aspects of the paid-versus-free version of MongoDB (the product line) are:
    • Security.
    • Management tools.
  • Well, actually, you can get the management tools for free, but only on a SaaS basis from MongoDB (the company).
    • If you want them on premises or in your part of the cloud, you need to pay.
    • If you want MongoDB (the company) to maintain your backups for you, you need to pay.
  • Customer counts include:
    • At least 1000 or so subscribers (counting by organization).
    • Over 500 (additional?) customers for remote backup.
    • 30 of the Fortune 100.

And finally, MongoDB did something many companies should, which is aggregate user success stories for which they may not be allowed to publish full details. Tidbits include:

  • Over 100 organizations run clusters with more than 100 nodes. Some clusters exceed 1,000 nodes.
  • Many clusters deliver hundreds of thousands of operations per second (combined read and write).
  • MongoDB clusters routinely store hundreds of terabytes, and some store multiple petabytes of data. Over 150 clusters exceed 1 billion documents in size. Many manage more than 100 billion documents.

SQL Developer’s Interface for GIT: Interacting with a GitHub Repository Part 2

Galo Balda's Blog - 18 hours 47 min ago

In this post I’m going to show to synchronize the remote and local repositories after an existing file in local gets modified. What I’ll do is modify the sp_test_git.pls file in our local repository and then push those changes to the remote repository (GitHub).

First, I proceed to open the sp_test_git.pls file using SQL Developer, add another dbms_output line to it and save it. The moment I save the file, the Pending Changes (Git) window gets updated to reflect the change and the icons in the toolbar get enabled.

modify_file

Now I can include a comment and then add the file to the staging area by clicking on the Add button located on the Pending Changes (Git) window. Notice how the status changes from “Modified Not Staged” to “Modified Staged”.

staged_file

What if I want to compare versions before doing a commit to the local repository? I just have to click on the Compare with Previous Version icon located on the Pending Changes (Git) window.

compare2

The panel on the left displays the version stored in the local repository and the panel on the right displays the version in the Staging Area.

The next step is to commit the changes to the local repository. For that I click on the Commit button located on the Pending Changes (Git) window and then I click on the OK button in the Commit window.

commit

Now the Branch Compare window displays information telling that remote and local are out of sync.

branch_compare2

So the final step is to sync up remote and local by pushing the changes to GitHub. For that I go to the main menu and click on  Team -> Git -> Push to open the “Push to Git” wizard where I enter the URL for the remote repository, the user name and password to complete the operation. Now I go to GitHub to confirm the changes have been applied.

ORA-00600 [3631] recovering pluggable database after flashback database in Oracle 12c

Bobby Durrett's DBA Blog - Wed, 2014-04-16 15:44

I was trying to recreate the scenario where a 12c container database is flashed back to a SCN before the point that I recovered a pluggable database to using point in time recovery.

I got this ugly ORA-00600:

RMAN> recover pluggable database pdborcl;

Starting recover at 16-APR-14
using channel ORA_DISK_1

starting media recovery
media recovery failed
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 04/16/2014 06:07:40
ORA-00283: recovery session canceled due to errors
RMAN-11003: failure during parse/execution of SQL statement: alter database recover if needed
 datafile 32 , 33 , 34 , 35
ORA-00283: recovery session canceled due to errors
ORA-00600: internal error code, arguments: [3631], [32], [4096], [4210689], [], [], [], [], [], [], [], []

I think the above error message stems from this bug:

Bug 14536110  ORA-600 [ktfaput: wrong pdb] / crash using PDB and FDA

There may have been some clever way to recover from this but I ended up just deleting and recreating the CDB through DBCA which was good experience playing with DBCA in Oracle 12c.  I’m trying to learn 12c but I have a feeling that I have hit a bug that keeps me from testing this flashback database, point in time recovery of a pluggable database scenario.  I wonder if I should patch?  I think that Oracle has included a patch for this bug in a patch set.  It could be good 12c experience to apply a patch set.

Retailers use business intelligence to optimize supply chain

Chris Foot - Wed, 2014-04-16 10:07

Due to the prevalence of omnichannel retail, merchandisers are obligated to satisfy the inventory fulfillment requirements of brick-and-mortar stores and consumers. Instead of using human resources to scrutinize the distribution process, commodity-based companies are hiring database experts to implement business intelligence tools capable of providing actionable information regarding the supply chain.

What's redefining modern delivery systems?
E-commerce has allowed corporations to deliver their products to consumers residing in various parts of the country, creating variable demand for particular items. In order to anticipate customer desires, data analytics tools are being used to chart regional weather conditions, translate online surveys and monitor the distribution of materials. Jim Rice, a contributor to Supply Chain 24/7, stated that while transportation and storage processes cannot change the specifications of an item, they can revolutionize the way in which that particular product is delivered to a customer.

For example, a customized, direct-to-order method can transform consumer expectations. People don't want to wait to receive their purchased materials, even though an unspoken covenant was established the minute they finalized the order on a website. Therefore, database administration personnel employ programs that scrutinize which areas of the supply chain can be optimized to ensure that products are delivered as promptly as possible. The patterns these software solutions recognize are often overlooked by human eyes.

Enhancing global sourcing
Database engineering company Oracle recently announced the introduction of Oracle Global Trade Intelligence, a global commerce analytics application that provides organizations with the ability to leverage worldwide sourcing and distribution data to measure, predict and optimize the performance of their supply chains. Released in February, the program contains modifiable dashboards that enable enterprises to construct user-defined trade performance measurements that scrutinize import and export activities throughout the world.

Oracle experts and sourcing professionals are thrilled with the release, which also offers executives the chance to streamline communications between overseas departments. This process is expected to ensure that all materials are properly tracked, significantly reducing the chance of losing vital products. In addition, the program gives strategists the ability to anticipate the actions of both foreign and domestic competitors.

"Organizations are moving beyond automation of their global trade processes and are seeking ways to leverage their global trade data to make better business decisions," said Vice President of Value Chain Execution Product Strategy Derek Gittoes.

In the age of global commerce, it's imperative that companies possess programs akin to Oracle Global Trade Intelligence in order expedite the shipment of goods and reduce the cost for such products on the consumer's end.

Monitoring Oracle Golden Gate from SQL Developer

DBASolved - Wed, 2014-04-16 07:16

Last week I was at Collaborate 14 speaking in two sessions; one of the sessions I had done a couple of times before.  The other session was about the different ways of monitoring Oracle GoldenGate (If you are curious about the presentation it can be found here).  While at the conference I ran the idea of monitoring GoldenGate from SQL Developer by a few peers and there seems to be interest.  As for Oracle, this approach to monitoring GoldenGate is not on Oracle’s road map for SQL Developer.

To achieve this goal, the usage of XML extensions within SQL Developer is needed.  Using XML extensions, I’ve been able to leverage monitoring GoldenGate from SQL into a working extension.  The extension is not perfect and continues to need some work.  As you can see in image 1, I can get the status of a GoldenGate process and associated stats.

Image 1:image

The SQL Developer extension for Oracle GoldenGate is available for whoever would like to use it and extend on it.  This extension is included with my other GoldenGate monitoring scripts located here and on my scripts page.

Note: at some point, I will hopefully get this extension uploaded to a Github repository for community digestion.

This extension is to help DBAs have a way to monitor their GoldenGate environments without the need of going directly to the server. For now, it just gives up/down status and operation stats.  Hopefully, as this matures (as I and others work on it) it will become a robust extension for all monitoring with Oracle GoldenGate.

Enjoy!

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.

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.
