• First Day of Data Integration Track at Oracle OpenWorld 2012

  - by Irem Radzik

  OpenWorld started full speed for us today with a great set of sessions in the Data Integration track. After the exciting keynote session on Oracle Database 12c in the morning; Brad Adelberg, VP of Development for Data Integration products, presented Oracle’s data integration product strategy. His session highlighted the new requirements for data integration to achieve pervasive and continuous access to trusted data. The new requirements and product focus areas presented in this session are: Provide access to any data at any source On premise or on cloud Enable zero downtime operations and maximum performance Leverage real-time data for accurate business insights And ensure high quality data is used across the enterprise During the session Brad walked over how Oracle’s data integration products, Oracle Data Integrator, Oracle GoldenGate, Oracle Enterprise Data Quality, and Oracle Data Service Integrator, deliver on these requirements and how recent product releases build on this strategy. Soon after Brad’s session we heard from a panel of Oracle GoldenGate customers, St. Jude Medical, Equifax, and Bank of America, how they achieved zero downtime operations using Oracle GoldenGate. The panel presented different use cases of GoldenGate, from Active-Active replication to offloading reporting. Especially St. Jude Medical’s implementation, which involves the alert management system for patients that use their pacemakers, reminded me in some cases downtime of mission-critical systems can be a matter of life or death. It is very comforting to hear that GoldenGate delivers highly-reliable continuous availability for life-saving medical systems. In the afternoon, Nick Wagner from the Product Management team and I followed the customer panel with the review of Oracle GoldenGate 11gR2’s New Features.  Many questions we received from audience were about GoldenGate’s new Integrated Capture for Oracle Database and the enhanced Conflict Management features, as well as how GoldenGate compares to Oracle Streams. In addition to giving details on GoldenGate’s unique capability to capture changed data with a direct integration to the Oracle DBMS engine, we reminded the audience that enhancements to Oracle GoldenGate will continue, while Streams will be primarily maintained. Last but not least, Tim Garrod and Ryan Fonnett from Raymond James presented a unified real-time data integration solution using Oracle Data Integrator and GoldenGate for their operational data store (ODS). The ODS supports application services across the enterprise and providing timely data is a critical requirement. In this solution, Oracle GoldenGate does the log-based change data capture for Oracle Data Integrator’s near real-time data integration between heterogeneous systems. As Raymond James’ ODS supports mission-critical services for their advisors, the project team had to set up this integration environment to be highly available. During the session, Ryan and Tim explained how they use ODI to enable automated process execution and “always-on” integration processes. Their presentation included 2 demonstrations that focused on CDC patterns deployed with ODI and the automated multi-instance execution and monitoring. We are very grateful to Tim and Ryan for their very-well prepared presentation at OpenWorld this year. Day 2 (Tuesday) will be also a busy day in our track. In addition to the Fusion Middleware Innovation Awards ceremony at 11:45am at Moscone West 3001, we have the following DI sessions Real-World Operational Reporting Customer Panel 11:45am Moscone West- 3005 Oracle Data Integrator Product Update and Future Strategy 1:15pm Moscone West- 3005 High-volume OLTP with Oracle GoldenGate: Best Practices from Comcast 1:15pm Moscone West- 3005 Everything You need to Know about Monitoring Oracle GoldenGate 5pm Moscone West-3005 If you are at OpenWorld please join us in these sessions. For a full review of data integration track at OpenWorld please see our Focus-On document.

• Bitmask data insertions in SSDT Post-Deployment scripts

  - by jamiet

  On my current project we are using SQL Server Data Tools (SSDT) to manage our database schema and one of the tasks we need to do often is insert data into that schema once deployed; the typical method employed to do this is to leverage Post-Deployment scripts and that is exactly what we are doing. Our requirement is a little different though, our data is split up into various buckets that we need to selectively deploy on a case-by-case basis. I was going to use a SQLCMD variable for each bucket (defaulted to some value other than “Yes”) to define whether it should be deployed or not so we could use something like this in our Post-Deployment script: IF ($(DeployBucket1Flag) = 'Yes')BEGIN   :r .\Bucket1.data.sqlENDIF ($(DeployBucket2Flag) = 'Yes')BEGIN   :r .\Bucket2.data.sqlENDIF ($(DeployBucket3Flag) = 'Yes')BEGIN   :r .\Bucket3.data.sqlEND That works fine and is, I’m sure, a very common technique for doing this. It is however slightly ugly because we have to litter our deployment with various SQLCMD variables. My colleague James Rowland-Jones (whom I’m sure many of you know) suggested another technique – bitmasks. I won’t go into detail about how this works (James has already done that at Using a Bitmask - a practical example) but I’ll summarise by saying that you can deploy different combinations of the buckets simply by supplying a different numerical value for a single SQLCMD variable. Each bit of that value’s binary representation signifies whether a particular bucket should be deployed or not. This is better demonstrated using the following simple script (which can be easily leveraged inside your Post-Deployment scripts): /* $(DeployData) is a SQLCMD variable that would, if you were using this in SSDT, be declared in the SQLCMD variables section of your project file. It should contain a numerical value, defaulted to 0. In this example I have declared it using a :setvar statement. Test the affect of different values by changing the :setvar statement accordingly. Examples: :setvar DeployData 1 will deploy bucket 1 :setvar DeployData 2 will deploy bucket 2 :setvar DeployData 3   will deploy buckets 1 & 2 :setvar DeployData 6   will deploy buckets 2 & 3 :setvar DeployData 31  will deploy buckets 1, 2, 3, 4 & 5 */ :setvar DeployData 0 DECLARE  @bitmask VARBINARY(MAX) = CONVERT(VARBINARY,$(DeployData)); IF (@bitmask & 1 = 1) BEGIN     PRINT 'Bucket 1 insertions'; END IF (@bitmask & 2 = 2) BEGIN     PRINT 'Bucket 2 insertions'; END IF (@bitmask & 4 = 4) BEGIN     PRINT 'Bucket 3 insertions'; END IF (@bitmask & 8 = 8) BEGIN     PRINT 'Bucket 4 insertions'; END IF (@bitmask & 16 = 16) BEGIN     PRINT 'Bucket 5 insertions'; END An example of running this using DeployData=6 The binary representation of 6 is 110. The second and third significant bits of that binary number are set to 1 and hence buckets 2 and 3 are “activated”. Hope that makes sense and is useful to some of you! @Jamiet P.S. I used the awesome HTML Copy feature of Visual Studio’s Productivity Power Tools in order to format the T-SQL code above for this blog post.

• Live Event: OTN Architect Day: Cloud Computing - Two weeks and counting

  - by Bob Rhubart

  In just two weeks architects and others will gather at the Oracle Conference Center in Redwood Shores, CA for the first Oracle Technology Network Architect Day event of 2013. This event focuses on Cloud Computing, and features sessions specifically focused on real-world examples of the implementation of cloud computing. When: Tuesday July 9, 2013              8:30am - 12:30pm Where: Oracle Conference Center              350 Oracle Pkwy              Redwood City, CA 94065 Register now. It's free! Here's the agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Michael Timpanaro-Perrotta Director, Product Management, Oracle Database Cloud New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Michael Timpanaro-Perrotta respond to audience questions. Registration is free, but seating is limited, so register now.

• C# reference collection for storing reference types

  - by ivo s

  I like to implement a collection (something like List<T>) which would hold all my objects that I have created in the entire life span of my application as if its an array of pointers in C++. The idea is that when my process starts I can use a central factory to create all objects and then periodically validate/invalidate their state. Basically I want to make sure that my process only deals with valid instances and I don't re-fetch information I already fetched from the database. So all my objects will basically be in one place - my collection. A cool thing I can do with this is avoid database calls to get data from the database if I already got it (even if I updated it after retrieval its still up-to-date if of course some other process didn't update it but that a different concern). I don't want to be calling new Customer("James Thomas"); again if I initted James Thomas already sometime in the past. Currently I will end up with multiple copies of the same object across the appdomain - some out of sync other in sync and even though I deal with this using timestamp field on the MSSQL server I'd like to keep only one copy per customer in my appdomain (if possible process would be better). I can't use regular collections like List or ArrayList for example because I cannot pass parameters by their real local reference to the their existing Add() methods where I'm creating them using ref so that's not to good I think. So how can this be implemented/can it be implemented at all ? A 'linked list' type of class with all methods working with ref & out params is what I'm thinking now but it may get ugly pretty quickly. Is there another way to implement such collection like RefList<T>.Add(ref T obj)? So bottom line is: I don't want re-create an object if I've already created it before during the entire application life unless I decide to re-create it explicitly (maybe its out-of-date or something so I have to fetch it again from the db). Is there alternatives maybe ?

• NSPopupButton Bindings with Value Transformer

  - by rdelmar

  I don't know if what I see with a popup button populated by bindings with a value transformer is the way it's supposed to be or not -- the unusual thing I'm seeing (at least with respect to what I've seen with value transformers and table views) is that the "value" parameter in the transformedValue: method is the whole array bound to the array controller, not the individual strings in the array. When I've done this with table views, the transformer is called once for each displayed row in the table, and the "value" parameter is whatever object is bound to that row and column, not the whole array that serves as the content array for the array controller. I have a very simple app to test this. In the app delegate there is this: +(void)initialize { RDTransformer *transformer = [[RDTransformer alloc] init]; [NSValueTransformer setValueTransformer:transformer forName:@"testTransformer"]; } - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.theData = @[@{@"name":@"William", @"age":@"24"},@{@"name":@"Thomas", @"age":@"23"},@{@"name":@"Alexander", @"age":@"64"},@{@"name":@"James", @"age":@"47"}]; } In the RDTransformer class is this: + (Class)transformedValueClass { return [NSString class]; } +(BOOL)allowsReverseTransformation { return NO; } -(id)transformedValue:(id)value { NSLog(@"%@",value); return value; } In IB, I added an NSPopupButton to the window and an array controller to the objects list. The content array of the controller is bound to App Delegate.theData, and the Content Values of the popup button is bound to Array Controller.arrangedObjects.name with the value transformer, testTransformer. When I run the program, the log from the transformedValue: method is this: 2012-09-19 20:31:39.975 PopupBindingWithTransformer[793:303] ( ) 2012-09-19 20:31:40.019 PopupBindingWithTransformer[793:303] ( William, Thomas, Alexander, James ) This doesn't seem to be other people's experience from what I can see on SO. Is there something I'm doing wrong with either the bindings or the value transformer?

• Perl regex which grabs ALL double letter occurances in a line

  - by phileas fogg

  Hi all, still plugging away at teaching myself Perl. I'm trying to write some code that will count the lines of a file that contain double letters and then place parentheses around those double letters. Now what I've come up with will find the first ocurrance of double letters, but not any other ones. For instance, if the line is: Amp, James Watt, Bob Transformer, etc. These pioneers conducted many My code will render this: 19 Amp, James Wa(tt), Bob Transformer, etc. These pioneers conducted many The "19" is the count (of lines containing double letters) and it gets the "tt" of "Watt" but misses the "ee" in "pioneers". Below is my code: $file = '/path/to/file/electricity.txt'; open(FH, $file) || die "Cannot open the file\n"; my $counter=0; while (<FH>) { chomp(); if (/(\w)\1/) { $counter += 1; s/$&/\($&\)/g; print "\n\n$counter $_\n\n"; } else { print "$_\n"; } } close(FH); What am I overlooking? TIA!

• Refreshing and alerting only when a keyword appears?

  - by Straightfw

  I know of the addons which reload the page and inform about any change on the website like Check4Change and Reload Every for Firefox. However, I'd love to have something which not only looks for any change but for a particular keyword or a list of keywords. I mean: something that I can configure to look for, say, "Jesse James" and it reloads every n seconds but gives me an alert/sound only when this keyword appears on the site, ignoring any other content chagne. Is there anything like this for any browser?

• Securing debain with fail2ban or iptables

  - by Jimmy

  I'm looking to secure my server. Initially my first thought was to use iptables but then I also learnt about Fail2ban. I understand that Fail2ban is based on iptables, but it has the advantages of being able to ban IP's after a number of attempts. Let's say I want to block FTP completely: Should I write a separate IPtable rule to block FTP, and use Fail2ban just for SSH Or instead simply put all rules, even the FTP blocking rule within the Fail2Ban config Any help on this would be appreciated.

  I have a new Windows 7 64bit laptop, which connects wirelessly to a ASDL router/modem. With my regular connection, page requests often time out - usually with form submissions. When I use the same connection to connect to a VPN (using OpenVPN) the requests seem to work fine. These are not requests to sites that are only available via the VPN - just regular websites I think this is specific to this new laptop (provided and set up by my employer) - other machines work fine. Many thanks for any advice, James

• PowerShell PowerPack Download

  - by BuckWoody

  I read Jeffery Hicks’ article in this month’s Redmond Magazine on a new add-in for Windows PowerShell 2.0. It’s called the PowerShell Pack and it has a some great new features that I plan to put into place on my production systems as soon as I finished learning and testing them. You can download the pack here if you have PowerShell 2.0. I’m having a lot of fun with it, and I’ll blog about what I’m learning here in the near future, but you should check it out. The only issue I have with it right now is that you have to load a module and then use get-help to find out what it does, because I haven’t found a lot of other documentation so far. The most interesting modules for me are the ones that can run a command elevated (in PSUserTools), the task scheduling commands (in TaskScheduler) and the file system checks and tools (in FileSystem). There’s also a way to create simple Graphical User Interface panels (in ). I plan to string all these together to install a management set of tools on my SQL Server Express Instances, giving the user “task buttons” to backup or restore a database, add or delete users and so on. Yes, I’ll be careful, and yes, I’ll make sure the user is allowed to do that. For now, I’m testing the download, but I thought I would share what I’m up to. If you have PowerShell 2.0 and you download the pack, let me know how you use it.

• Understanding Data Science: Recent Studies

  - by Joe Lamantia

  If you need such a deeper understanding of data science than Drew Conway's popular venn diagram model, or Josh Wills' tongue in cheek characterization, "Data Scientist (n.): Person who is better at statistics than any software engineer and better at software engineering than any statistician." two relatively recent studies are worth reading.   'Analyzing the Analyzers,' an O'Reilly e-book by Harlan Harris, Sean Patrick Murphy, and Marck Vaisman, suggests four distinct types of data scientists -- effectively personas, in a design sense -- based on analysis of self-identified skills among practitioners.  The scenario format dramatizes the different personas, making what could be a dry statistical readout of survey data more engaging.  The survey-only nature of the data,  the restriction of scope to just skills, and the suggested models of skill-profiles makes this feel like the sort of exercise that data scientists undertake as an every day task; collecting data, analyzing it using a mix of statistical techniques, and sharing the model that emerges from the data mining exercise.  That's not an indictment, simply an observation about the consistent feel of the effort as a product of data scientists, about data science.  And the paper 'Enterprise Data Analysis and Visualization: An Interview Study' by researchers Sean Kandel, Andreas Paepcke, Joseph Hellerstein, and Jeffery Heer considers data science within the larger context of industrial data analysis, examining analytical workflows, skills, and the challenges common to enterprise analysis efforts, and identifying three archetypes of data scientist.  As an interview-based study, the data the researchers collected is richer, and there's correspondingly greater depth in the synthesis.  The scope of the study included a broader set of roles than data scientist (enterprise analysts) and involved questions of workflow and organizational context for analytical efforts in general.  I'd suggest this is useful as a primer on analytical work and workers in enterprise settings for those who need a baseline understanding; it also offers some genuinely interesting nuggets for those already familiar with discovery work. We've undertaken a considerable amount of research into discovery, analytical work/ers, and data science over the past three years -- part of our programmatic approach to laying a foundation for product strategy and highlighting innovation opportunities -- and both studies complement and confirm much of the direct research into data science that we conducted. There were a few important differences in our findings, which I'll share and discuss in upcoming posts.

  In my part of the world the weather has taken its seasonal turn toward the kind of cold, damp, miserable stuff that offers a major motivation to stay indoors. While I plan to spend some of the indoor time working my way through the new 50th anniversary James Bond box set, I will also devote some time to improve my mind rather than my martini-mixing skills by catching up on my reading.

• The Top Ten Security Top Ten Lists

  - by Troy Kitch

  As a marketer, we're always putting together the top 3, or 5 best, or an assortment of top ten lists. So instead of going that route, I've put together my top ten security top ten lists. These are not only for security practitioners, but also for the average Joe/Jane; because who isn't concerned about security these days? Now, there might not be ten for each one of these lists, but the title works best that way. Starting with my number ten (in no particular order): 10. Top 10 Most Influential Security-Related Movies Amrit Williams pulls together a great collection of security-related movies. He asks for comments on which one made you want to get into the business. I would have to say that my most influential movie(s), that made me want to get into the business of "stopping the bad guys" would have to be the James Bond series. I grew up on James Bond movies: thwarting the bad guy and saving the world. I recall being both ecstatic and worried when Silicon Valley-themed "A View to A Kill" hit theaters: "An investigation of a horse-racing scam leads 007 to a mad industrialist who plans to create a worldwide microchip monopoly by destroying California's Silicon Valley." Yikes! 9. Top Ten Security Careers From movies that got you into the career, here’s a top 10 list of security-related careers. It starts with number then, Information Security Analyst and ends with number one, Malware Analyst. They point out the significant growth in security careers and indicate that "according to the Bureau of Labor Statistics, the field is expected to experience growth rates of 22% between 2010-2020. If you are interested in getting into the field, Oracle has many great opportunities all around the world.  8. Top 125 Network Security Tools A bit outside of the range of 10, the top 125 Network Security Tools is an important list because it includes a prioritized list of key security tools practitioners are using in the hacking community, regardless of whether they are vendor supplied or open source. The exhaustive list provides ratings, reviews, searching, and sorting. 7. Top 10 Security Practices I have to give a shout out to my alma mater, Cal Poly, SLO: Go Mustangs! They have compiled their list of top 10 practices for students and faculty to follow. Educational institutions are a common target of web based attacks and miscellaneous errors according to the 2014 Verizon Data Breach Investigations Report.    6. (ISC)2 Top 10 Safe and Secure Online Tips for Parents This list is arguably the most important list on my list. The tips were "gathered from (ISC)2 member volunteers who participate in the organization’s Safe and Secure Online program, a worldwide initiative that brings top cyber security experts into schools to teach children ages 11-14 how to protect themselves in a cyber-connected world…If you are a parent, educator or organization that would like the Safe and Secure Online presentation delivered at your local school, or would like more information about the program, please visit here.” 5. Top Ten Data Breaches of the Past 12 Months This type of list is always changing, so it's nice to have a current one here from Techrader.com. They've compiled and commented on the top breaches. It is likely that most readers here were effected in some way or another. 4. Top Ten Security Comic Books Although mostly physical security controls, I threw this one in for fun. My vote for #1 (not on the list) would be Professor X. The guy can breach confidentiality, integrity, and availability just by messing with your thoughts. 3. The IOUG Data Security Survey's Top 10+ Threats to Organizations The Independent Oracle Users Group annual survey on enterprise data security, Leaders Vs. Laggards, highlights what Oracle Database users deem as the top 12 threats to their organization. You can find a nice graph on page 9; Figure 7: Greatest Threats to Data Security. 2. The Ten Most Common Database Security Vulnerabilities Though I don't necessarily agree with all of the vulnerabilities in this order...I like a list that focuses on where two-thirds of your sensitive and regulated data resides (Source: IDC).  1. OWASP Top Ten Project The Online Web Application Security Project puts together their annual list of the 10 most critical web application security risks that organizations should be including in their overall security, business risk and compliance plans. In particular, SQL injection risks continues to rear its ugly head each year. Oracle Audit Vault and Database Firewall can help prevent SQL injection attacks and monitor database and system activity as a detective security control. Did I miss any?

• Why was Mr. Scott Scottish?

  - by iamjames

  It's a good question:  of all the engineers in the world, why choose a Scottish engineer?  The Gene Roddenberry probably chose a Scottish engineer because of this guy: That's James Watt, the same guy the unit of energy watt is named after.  He was a Scottish inventor and mechancial engineer who built the first made significant improvements to the steam engine.  Made sense in the 60's, however given the past hundred years if they were to make a new Star Trek they might have started with a German engineer (or maybe Japanese), but since World War II had ended barely 20 years earlier the 20-somethings that had survived the war were now 40-somethings and seeing a German engineer probably wouldn't have gone over too well.
