• Oracle Open World 2012: SQL Developer Recap

  - by thatjeffsmith

  Last week was the ‘big show’ in San Francisco. I was very happy to meet many of you in person. And many of you had questions – lots of questions! We had full or overflowing rooms for our sessions and hands-on-labs. The SQL Developer ‘booths’ were also slammed several times. So exciting to see so many of YOU excited about SQL Developer. It’s very cool to hear the stories of our tools saving you and your organizations so much time (and money!) Instead of doing a Day 0 – Day 9 recap, I thought I’d share with you the questions that I heard more than once. And just for giggles, I’ll throw in some answers as well So in no particular order… What’s the difference between Oracle SQL Developer & Oracle SQL Developer Data Modeler? Mathematically speaking – two words. But as far as the actual modeling features go, there’s no difference between the two applications. The same ‘code’ or features as it pertains to data modeling and design are in both tools. However, in SQL Developer you have all of the OTHER features fighting for real estate in the UI. So I have a general rule of thumb – if you spend MOST of your time in the database, use SQL Developer. And if you spend most of your time in the data model, run the separate and dedicated program, Oracle SQL Developer Data Modeler. Here’s a couple of screenshots to drive home the UI point: Oracle SQL Developer Oracle SQL Developer Data Modeler running INSIDE of SQL Developer. Notice how the Modeler menu items fold under the file menu? Oracle SQL Developer Data Modeler Easier to navigate and manipulate your models with the stand alone modeler. Just no worksheet to run your ad-hoc queries, etc. Don’t forget you can disable the Data Modeler inside of SQL Developer via the Extensions preference page. How can I model my table partitions? Partitioning is defined via the Physical model. So after you have finished your relational model, you need to generate a physical model. Oracle SQL Developer Data Modeler Physical Model and Partitioning Open the properties for your physical model table. Enable the ‘partitioned’ property. Once you do so, the ‘Partitioning’ page will activate. Lots and lots of partitioning support and options here But what about Interval Partitioning? An extension of range partitioning in 11gR2, we don’t currently support this partitioning scheme in SQL Developer. But we’re working on it! Can SQL Developer ignore column order when comparing models? Yes! After you start a model compare, one of your options is to disregard the order of an attribute or column definition. Tell SQL Developer you don’t care when your column shows up, just as long as it DOES show up. Wow, you got a lot of questions around modeling! Is that normal? Yes! While we appreciate that many folks inherit their applications and associated designs, new applications are being ‘born’ every day. Since both of our tools are free for anyone to design their new Oracle applications with, we attract a fair amount of attention I want to do a Hands On Lab. How do I get your software and instructional guides? Go here. Download VirtualBox. Then download the VB image. Import the appliance. Start it. Connect oracle/oracle on the OEL VM. Click on ‘Start Here’ in the desktop. Follow the instructions. If you need help, ask away! You went too fast in your Tips & Tricks session. Do you have cliff notes? Yes! And you’re SO close to finding them! Just go to my SQL Developer resources page. All of my tips are documented on this blog somewhere. I’ve indexed the most popular ones on the resource page. You can use the Search dialog on the right to find the rest. Or just send me a comment or question, and I’ll do my best to answer them as they come in.

• Should I create separate Work and Personal Github accounts?

  - by Almost Surely

  I'm fairly new to programming, and I've been working on many personal projects, which I'm concerned can come across as silly/unprofessional. The kind of projects I have are a Reddit Image Downloader and a tool for GM's to use in roleplaying games. I want to start building up a Github for projects in my chosen field of Data Analytics, but I'm not sure how to orgaqnize projects on my Github account. Should I create a "Professional" Github, mainly containing different analytical scripts and have a separate "Personal" account for fun little projects of mine? Or am I just overthinking this and should I just maintain account?

• How to Use An Antivirus Boot Disc or USB Drive to Ensure Your Computer is Clean

  - by Chris Hoffman

  If your computer is infected with malware, running an antivirus within Windows may not be enough to remove it. If your computer has a rootkit, the malware may be able to hide itself from your antivirus software. This is where bootable antivirus solutions come in. They can clean malware from outside the infected Windows system, so the malware won’t be running and interfering with the clean-up process. The Problem With Cleaning Up Malware From Within Windows Standard antivirus software runs within Windows. If your computer is infected with malware, the antivirus software will have to do battle with the malware. Antivirus software will try to stop the malware and remove it, while the malware will attempt to defend itself and shut down the antivirus. For really nasty malware, your antivirus software may not be able to fully remove it from within Windows. Rootkits, a type of malware that hides itself, can be even trickier. A rootkit could load at boot time before other Windows components and prevent Windows from seeing it, hide its processes from the task manager, and even trick antivirus applications into believing that the rootkit isn’t running. The problem here is that the malware and antivirus are both running on the computer at the same time. The antivirus is attempting to fight the malware on its home turf — the malware can put up a fight. Why You Should Use an Antivirus Boot Disc Antivirus boot discs deal with this by approaching the malware from outside Windows. You boot your computer from a CD or USB drive containing the antivirus and it loads a specialized operating system from the disc. Even if your Windows installation is completely infected with malware, the special operating system won’t have any malware running within it. This means the antivirus program can work on the Windows installation from outside it. The malware won’t be running while the antivirus tries to remove it, so the antivirus can methodically locate and remove the harmful software without it interfering. Any rootkits won’t be able to set up the tricks they use at Windows boot time to hide themselves from the rest o the operating system. The antivirus will be able to see the rootkits and remove them. These tools are often referred to as “rescue disks.” They’re meant to be used when you need to rescue a hopelessly infected system. Bootable Antivirus Options As with any type of antivirus software, you have quite a few options. Many antivirus companies offer bootable antivirus systems based on their antivirus software. These tools are generally free, even when they’re offered by companies that specialized in paid antivirus solutions. Here are a few good options: avast! Rescue Disk – We like avast! for offering a capable free antivirus with good detection rates in independent tests. avast! now offers the ability to create an antivirus boot disc or USB drive. Just navigate to the Tools -> Rescue Disk option in the avast! desktop application to create bootable media. BitDefender Rescue CD – BitDefender always seems to receive good scores in independent tests, and the BitDefender Rescue CD offers the same antivirus engine in the form of a bootable disc. Kaspersky Rescue Disk – Kaspersky also receives good scores in independent tests and offers its own antivirus boot disc. These are just a handful of options. If you prefer another antivirus for some reason — Comodo, Norton, Avira, ESET, or almost any other antivirus product — you’ll probably find that it offers its own system rescue disk. How to Use an Antivirus Boot Disc Using an antivirus boot disc or USB drive is actually pretty simple. You’ll just need to find the antivirus boot disc you want to use and burn it to disc or install it on a USB drive. You can do this part on any computer, so you can create antivirus boot media on a clean computer and then take it to an infected computer. Insert the boot media into the infected computer and then reboot. The computer should boot from the removable media and load the secure antivirus environment. (If it doesn’t, you may need to change the boot order in your BIOS or UEFI firmware.) You can then follow the instructions on your screen to scan your Windows system for malware and remove it. No malware will be running in the background while you do this. Antivirus boot discs are useful because they allow you to detect and clean malware infections from outside an infected operating system. If the operating system is severely infected, it may not be possible to remove — or even detect — all the malware from within it. Image Credit: aussiegall on Flickr

• Updating the managed debugging API for .NET v4

  - by Brian Donahue

  In any successful investigation, the right tools play a big part in collecting evidence about the state of the "crime scene" as it was before the detectives arrived. Unfortunately for the Crash Scene Investigator, we don't have the budget to fly out to the customer's site, chalk the outline, and eat their doughnuts. We have to rely on the end-user to collect the evidence for us, which means giving them the fingerprint dust and the evidence baggies and leaving them to it. With that in mind, the Red Gate support team have been writing tools that can collect vital clues with a minimum of fuss. Years ago we would have asked for a memory dump, where we used to get the customer to run CDB.exe and produce dumps that we could analyze in-house, but those dumps were pretty unwieldy (500MB files) and the debugger often didn't dump exactly where we wanted, or made five or more dumps. What we wanted was just the minimum state information from the program at the time of failure, so we produced a managed debugger that captured every first and second-chance exception and logged the stack and a minimal amount of variables from the memory of the application, which could all be exported as XML. This caused less inconvenience to the end-user because it is much easier to send a 65KB XML file in an email than a 500MB file containing all of the application's memory. We don't need to have the entire victim shipped out to us when we just want to know what was under the fingernails. The thing that made creating a managed debugging tool possible was the MDbg Engine example written by Microsoft as part of the Debugging Tools for Windows distribution. Since the ICorDebug interface is a bit difficult to understand, they had kindly created some wrappers that provided an event-driven debugging model that was perfect for our needs, but .NET 4 applications under debugging started complaining that "The debugger's protocol is incompatible with the debuggee". The introduction of .NET Framework v4 had changed the managed debugging API significantly, however, without an update for the MDbg Engine code! After a few hours of research, I had finally worked out that most of the version 4 ICorDebug interface still works much the same way in "legacy" v2 mode and there was a relatively easy fix for the problem in that you can still get a reference to legacy ICorDebug by changing the way the interface is created. In .NET v2, the interface was acquired using the CreateDebuggingInterfaceFromVersion method in mscoree.dll. In v4, you must first create IClrMetaHost, enumerate the runtimes, get an ICLRRuntimeInfo interface to the .NET 4 runtime from that, and use the GetInterface method in mscoree.dll to return a "legacy" ICorDebug interface. The rest of the MDbg Engine will continue working the old way. Here is how I had changed the MDbg Engine code to support .NET v4: private void InitFromVersion(string debuggerVersion){if( debuggerVersion.StartsWith("v1") ){throw new ArgumentException( "Can't debug a version 1 CLR process (\"" + debuggerVersion + "\"). Run application in a version 2 CLR, or use a version 1 debugger instead." );} ICorDebug rawDebuggingAPI=null;if (debuggerVersion.StartsWith("v4")){Guid CLSID_MetaHost = new Guid("9280188D-0E8E-4867-B30C-7FA83884E8DE"); Guid IID_MetaHost = new Guid("D332DB9E-B9B3-4125-8207-A14884F53216"); ICLRMetaHost metahost = (ICLRMetaHost)NativeMethods.ClrCreateInterface(CLSID_MetaHost, IID_MetaHost); IEnumUnknown runtimes = metahost.EnumerateInstalledRuntimes(); ICLRRuntimeInfo runtime = GetRuntime(runtimes, debuggerVersion); //Defined in metahost.hGuid CLSID_CLRDebuggingLegacy = new Guid(0xDF8395B5, 0xA4BA, 0x450b, 0xA7, 0x7C, 0xA9, 0xA4, 0x77, 0x62, 0xC5, 0x20);Guid IID_ICorDebug = new Guid("3D6F5F61-7538-11D3-8D5B-00104B35E7EF"); Object res;runtime.GetInterface(ref CLSID_CLRDebuggingLegacy, ref IID_ICorDebug, out res); rawDebuggingAPI = (ICorDebug)res; }elserawDebuggingAPI = NativeMethods.CreateDebuggingInterfaceFromVersion((int)CorDebuggerVersion.Whidbey,debuggerVersion);if (rawDebuggingAPI != null)InitFromICorDebug(rawDebuggingAPI);elsethrow new ArgumentException("Support for debugging version " + debuggerVersion + " is not yet implemented");} The changes above will ensure that the debugger can support .NET Framework v2 and v4 applications with the same codebase, but we do compile two different applications: one targeting v2 and the other v4. As a footnote I need to add that some missing native methods and wrappers, along with the EnumerateRuntimes method code, came from the Mindbg project on Codeplex. Another change is that when using the MDbgEngine.CreateProcess to launch a process in the debugger, do not supply a null as the final argument. This does not work any more because GetCORVersion always returns "v2.0.50727" as the function has been deprecated in .NET v4. What's worse is that on a system with only .NET 4, the user will be prompted to download and install .NET v2! Not nice! This works much better: proc = m_Debugger.CreateProcess(ProcessName, ProcessArgs, DebugModeFlag.Default,String.Format("v{0}.{1}.{2}",System.Environment.Version.Major,System.Environment.Version.Minor,System.Environment.Version.Build)); Microsoft "unofficially" plan on updating the MDbg samples soon, but if you have an MDbg-based application, you can get it working right now by changing one method a bit and adding a few new interfaces (ICLRMetaHost, IEnumUnknown, and ICLRRuntimeInfo). The new, non-legacy implementation of MDbg Engine will add new, interesting features like dump-file support and by association I assume garbage-collection/managed object stats, so it will be well worth looking into if you want to extend the functionality of a managed debugger going forward.

• Logical Domain Modeling Made Simple

  - by Knut Vatsendvik

  How can logical domain modeling be made simple and collaborative? Many non-technical end-users, managers and business domain experts find it difficult to understand the visual models offered by many UML tools. This creates trouble in capturing and verifying the information that goes into a logical domain model. The tools are also too advanced and complex for a non-technical user to learn and use. We have therefore, in our current project, ended up with using Confluence as tool for designing the logical domain model with the help of a few very useful plugins. Big thanks to Ole Nymoen and Per Spilling for their expertise in this field that made this posting possible. Confluence Plugins Here is a list of Confluence plugins used in this solution. Install these before trying out the macros used below. Plugin Description Copy Space Allows a space administrator to copy a space, including the pages within the space Metadata Supports adding metadata to Wiki pages Label Manages labeling of pages Linking Contains macros for linking to templates, the dashboard and other Table Enhances the table capability in Confluence Creating a Confluence Space First we need to create a new confluence space for the domain model. Click the link Create a Space located below the list of spaces on the Dashboard. Please contact your Confluence administrator is you do not have permissions to do this.   For illustrative purpose all attributes and entities in this posting are based on my imaginary project manager domain model. When a logical domain model is good enough for being implemented, do a copy of the Confluence Space (see Copy Space plugin). In this way you create a stable version of the logical domain model while further design can continue with the new copied space. Typical will the implementation phase result in a database design and/or a XSD schema design. Add Space Templates Go to the Home page of your Confluence Space. Navigate to the Browse drop-down menu and click on Advanced. Then click the Templates option in the left navigation panel. Click Add New Space Template to add the following three templates. Name: attribute {metadata-list} || Name | | || Type | | || Format | | || Description | | {metadata-list} {add-label:attribute} Name: primary-type {metadata-list} || Name | || || Type | || || Format | || || Description | || {metadata-list} {add-label:primary-type} Name: complex-type {metadata-list} || Name | || || Description |  || {metadata-list} h3. Attributes || Name || Type || Format || Description || | [name] | {metadata-from:name|Type} | {metadata-from:name|Format} | {metadata-from:name|Description} | {add-label:complex-type,entity} The metadata-list macro (see Metadata plugin) will save a list of metadata values to the page. The add-label macro (see Label plugin) will automatically label the page. Primary Types Page Our first page to add will act as container for our primary types. Switch to Wiki markup when adding the following content to the page. | (+) {add-page:template=primary-type|parent=@self}Add new primary type{add-page} | {metadata-report:Name,Type,Format,Description|sort=Name|root=@self|pages=@descendents} Once the page is created, click the Add new primary type (create-page macro) to start creating a new pages. Here is an example of input to the LocalDate page. Embrace the LocalDate with square brackets [] to make the page linkable. Again switch to Wiki markup before editing. {metadata-list} || Name | [LocalDate] || || Type | Date || || Format | YYYY-MM-DD || || Description | Date in local time zone. YYYY = year, MM = month and DD = day || {metadata-list} {add-label:primary-type} The metadata-report macro will show a tabular report of all child pages.   Attributes Page The next page will act as container for all of our attributes. | (+) {add-page:template=attribute|parent=@self|title=attribute}Add new attribute{add-page} | {metadata-report:Name,Type,Format,Description|sort=Name|pages=@descendants} Here is an example of input to the startDate page. {metadata-list} || Name | [startDate] || || Type | [LocalDate] || || Format | {metadata-from:LocalDate|Format} || || Description | The projects start date || {metadata-list} {add-label:attribute} Using the metadata-from macro we fetch the text from the previously created LocalDate page. Complex Types Page The last page in this example shows how attributes can be combined together to form more complex types.   h3. Intro Overview of complex types in the domain model. | (+) {add-page:template=complex-type|parent=@self}Add a new complex type{add-page}\\ | {metadata-report:Name,Description|sort=Name|root=@self|pages=@descendents} Here is an example of input to the ProjectType page. {metadata-list} || Name | [ProjectType] || || Description | Represents a project || {metadata-list} h3. Attributes || Name || Type || Format || Description || | [projectId] | {metadata-from:projectId|Type} | {metadata-from:projectId|Format} | {metadata-from:projectId|Description} | | [name] | {metadata-from:name|Type} | {metadata-from:name|Format} | {metadata-from:name|Description} | | [description] | {metadata-from:description|Type} | {metadata-from:description|Format} | {metadata-from:description|Description} | | [startDate] | {metadata-from:startDate|Type} | {metadata-from:startDate|Format} | {metadata-from:startDate|Description} | {add-label:complex-type,entity} Gives us this Conclusion Using a web-based corporate Wiki like Confluence to create a logical domain model increases the collaboration between people with different roles in the enterprise. It’s my believe that this helps the domain model to be more accurate, and better documented. In our real project we have more pages than illustrated here to complete the documentation. We do also still use UML tools to create different types of diagrams that Confluence do not support. As a last tip, an ImageMap plugin can make those diagrams clickable when used in pages. Enjoy!

• Help Protect Your Children with the CEOP Enhanced Internet Explorer 8

  - by Asian Angel

  Do you want to make Internet Explorer safer and more helpful for you and family? Then join us as we look at the CEOP (Child Exploitation and Online Protection Centre) enhanced version of Internet Explorer 8. Setting CEOP Up We chose to install the whole CEOP pack in order to have access to complete set of CEOP Tools. The install process will be comprised of two parts…it will begin with CEOP branded windows showing the components being installed… Note: The components can be downloaded separately for those who only want certain CEOP components added to their browser. Then it will move to the traditional Microsoft Internet Explorer 8 install windows. One thing that we did notice is that here you will be told that you will need to restart your computer but in other windows a log off/log on process is mentioned. Just to make certain that everything goes smoothly we recommend restarting your computer when the installation process is complete. In the EULA section you can see the versions of Windows that the CEOP Pack works with. Once you get past the traditional Microsoft install windows you will be dropped back into the CEOP branded windows. CEOP in Action After you have restarted your computer and opened Internet Explorer you will notice that your homepage has been changed. When it comes to your children that is not a bad thing in this instance. It will also give you an opportunity to look through the CEOP online resources. For the moment you may be wondering where everything is but do not worry. First you can find the two new search providers in the drop-down menu for your “Search Bar” and select a new default if desired. The second thing to look for are the new links that have been added to your “Favorites Menu”. These links can definitely be helpful for you and your family. The third part will require your “Favorites Bar” to be visible in order to see the “Click CEOP Button”. If you have not previously done so you will need to turn on subscribing for “Web Slices”. Click on “Yes” to finish the subscription process. Clicking on the “CEOP Button” again will show all kinds of new links to help provide information for you and your children. Notice that the top part is broken down into “topic categories” while the bottom part is set up for “age brackets”…very nice for helping you focus on the information that you want and/or need. Looking for information and help on a particular topic? Clicking on the “Cyberbullying Link” for example will open the following webpage with information about cyberbullying and a link to get help with the problem. Need something that is focused on your child’s age group? Clicking on the “8-10? Link” as an example opened this page. Want information that is focused on you? The “Parent? Link” leads to this page. The “topic categories & age brackets” make the CEOP Button a very helpful and “family friendly” addition to Internet Explorer. Perhaps you (or your child) want to conduct a search for something that is affecting your child. As you type in a “search term” both of the search providers will provide helpful suggestions for dealing with the problem. We felt that these were very nice suggestions in both instances here… Conclusion We have been able to give you a good peek at what the CEOP Tools can do but the best way to see how helpful it can be for you and your family is try it for yourself. Your children’s safety and happiness is worth it.

• Test-Drive ASP.NET MVC Review

  - by Ben Griswold

  A few years back I started dallying with test-driven development, but I never fully committed to the practice. This wasn’t because I didn’t believe in the value of TDD; it was more a matter of not completely understanding how to incorporate “test first” into my everyday development. Back in my web forms days, I could point fingers at the framework for my ignorance and laziness. After all, web forms weren’t exactly designed for testability so who could blame me for not embracing TDD in those conditions, right? But when I switched to ASP.NET MVC and quickly found myself fresh out of excuses and it became instantly clear that it was time to get my head around red-green-refactor once and for all or I would regretfully miss out on one of the biggest selling points the new framework had to offer. I have previously written about how I learned ASP.NET MVC. It was primarily hands on learning but I did read a couple of ASP.NET MVC books along the way. The books I read dedicated a chapter or two to TDD and they certainly addressed the benefits of TDD and how MVC was designed with testability in mind, but TDD was merely an afterthought compared to, well, teaching one how to code the model, view and controller. This approach made some sense, and I learned a bunch about MVC from those books, but when it came to TDD the books were just a teaser and an opportunity missed.  But then I got lucky – Jonathan McCracken contacted me and asked if I’d review his book, Test-Drive ASP.NET MVC, and it was just what I needed to get over the TDD hump. As the title suggests, Test-Drive ASP.NET MVC takes a different approach to learning MVC as it focuses on testing right from the very start. McCracken wastes no time and swiftly familiarizes us with the framework by building out a trivial Quote-O-Matic application and then dedicates the better part of his book to testing first – first by explaining TDD and then coding a full-featured Getting Organized application inspired by David Allen’s popular book, Getting Things Done. If you are a learn-by-example kind of coder (like me), you will instantly appreciate and enjoy McCracken’s style – its fast-moving, pragmatic and focused on only the most relevant information required to get you going with ASP.NET MVC and TDD. The book continues with the test-first theme but McCracken moves away from the sample application and incorporates other practical skills like persisting models with NHibernate, leveraging Inversion of Control with the IControllerFactory and building a RESTful web service. What I most appreciated about this section was McCracken’s use of and praise for open source libraries like Rhino Mocks, SQLite and StructureMap (to name just a few) and productivity tools like ReSharper, Web Platform Installer and ASP.NET SQL Server Setup Wizard.  McCracken’s emphasis on real world, pragmatic development was clearly demonstrated in every tool choice, straight-forward code block and developer tip. Whether one is already familiar with the tools/tips or not, McCracken’s thought process is easily understood and appreciated. The final section of the book walks the reader through security and deployment – everything from error handling and logging with ELMAH, to ASP.NET Health Monitoring, to using MSBuild with automated builds, to the deployment  of ASP.NET MVC to various web environments. These chapters, like those prior, offer enough information and explanation to simply help you get the job done.  Do I believe Test-Drive ASP.NET MVC will turn you into an expert MVC developer overnight?  Well, no.  I don’t think any book can make that claim.  If that were possible, I think book list prices would skyrocket!  That said, Test-Drive ASP.NET MVC provides a solid foundation and a unique (and dare I say necessary) approach to learning ASP.NET MVC.  Along the way McCracken shares loads of very practical software development tips and references numerous tools and libraries. The bottom line is it’s a great ASP.NET MVC primer – if you’re new to ASP.NET MVC it’s just what you need to get started.  Do I believe Test-Drive ASP.NET MVC will give you everything you need to start employing TDD in your everyday development?  Well, I used to think that learning TDD required a lot of practice and, if you’re lucky enough, the guidance of a mentor or coach.  I used to think that one couldn’t learn TDD from a book alone. Well, I’m still no pro, but I’m testing first now and Jonathan McCracken and his book, Test-Drive ASP.NET MVC, played a big part in making this happen.  If you are an MVC developer and a TDD newb, Test-Drive ASP.NET MVC is just the book for you.

• SQL SERVER – Example of Performance Tuning for Advanced Users with DB Optimizer

  - by Pinal Dave

  Performance tuning is such a subject that everyone wants to master it. In beginning everybody is at a novice level and spend lots of time learning how to master the art of performance tuning. However, as we progress further the tuning of the system keeps on getting very difficult. I have understood in my early career there should be no need of ego in the technology field. There are always better solutions and better ideas out there and we should not resist them. Instead of resisting the change and new wave I personally adopt it. Here is a similar example, as I personally progress to the master level of performance tuning, I face that it is getting harder to come up with optimal solutions. In such scenarios I rely on various tools to teach me how I can do things better. Once I learn about tools, I am often able to come up with better solutions when I face the similar situation next time. A few days ago I had received a query where the user wanted to tune it further to get the maximum out of the performance. I have re-written the similar query with the help of AdventureWorks sample database. SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID; User had similar query to above query was used in very critical report and wanted to get best out of the query. When I looked at the query – here were my initial thoughts Use only column in the select statements as much as you want in the application Let us look at the query pattern and data workload and find out the optimal index for it Before I give further solutions I was told by the user that they need all the columns from all the tables and creating index was not allowed in their system. He can only re-write queries or use hints to further tune this query. Now I was in the constraint box – I believe * was not a great idea but if they wanted all the columns, I believe we can’t do much besides using *. Additionally, if I cannot create a further index, I must come up with some creative way to write this query. I personally do not like to use hints in my application but there are cases when hints work out magically and gives optimal solutions. Finally, I decided to use Embarcadero’s DB Optimizer. It is a fantastic tool and very helpful when it is about performance tuning. I have previously explained how it works over here. First open DBOptimizer and open Tuning Job from File >> New >> Tuning Job. Once you open DBOptimizer Tuning Job follow the various steps indicates in the following diagram. Essentially we will take our original script and will paste that into Step 1: New SQL Text and right after that we will enable Step 2 for Generating Various cases, Step 3 for Detailed Analysis and Step 4 for Executing each generated case. Finally we will click on Analysis in Step 5 which will generate the report detailed analysis in the result pan. The detailed pan looks like. It generates various cases of T-SQL based on the original query. It applies various hints and available hints to the query and generate various execution plans of the query and displays them in the resultant. You can clearly notice that original query had a cost of 0.0841 and logical reads about 607 pages. Whereas various options which are just following it has different execution cost as well logical read. There are few cases where we have higher logical read and there are few cases where as we have very low logical read. If we pay attention the very next row to original query have Merge_Join_Query in description and have lowest execution cost value of 0.044 and have lowest Logical Reads of 29. This row contains the query which is the most optimal re-write of the original query. Let us double click over it. Here is the query: SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID OPTION (MERGE JOIN) If you notice above query have additional hint of Merge Join. With the help of this Merge Join query hint this query is now performing much better than before. The entire process takes less than 60 seconds. Please note that it the join hint Merge Join was optimal for this query but it is not necessary that the same hint will be helpful in all the queries. Additionally, if the workload or data pattern changes the query hint of merge join may be no more optimal join. In that case, we will have to redo the entire exercise once again. This is the reason I do not like to use hints in my queries and I discourage all of my users to use the same. However, if you look at this example, this is a great case where hints are optimizing the performance of the query. It is humanly not possible to test out various query hints and index options with the query to figure out which is the most optimal solution. Sometimes, we need to depend on the efficiency tools like DB Optimizer to guide us the way and select the best option from the suggestion provided. Let me know what you think of this article as well your experience with DB Optimizer. Please leave a comment.

• Replication Services in a BI environment

  - by jorg

  In this blog post I will explain the principles of SQL Server Replication Services without too much detail and I will take a look on the BI capabilities that Replication Services could offer in my opinion. SQL Server Replication Services provides tools to copy and distribute database objects from one database system to another and maintain consistency afterwards. These tools basically copy or synchronize data with little or no transformations, they do not offer capabilities to transform data or apply business rules, like ETL tools do. The only “transformations” Replication Services offers is to filter records or columns out of your data set. You can achieve this by selecting the desired columns of a table and/or by using WHERE statements like this: SELECT <published_columns> FROM [Table] WHERE [DateTime] >= getdate() - 60 There are three types of replication: Transactional Replication This type replicates data on a transactional level. The Log Reader Agent reads directly on the transaction log of the source database (Publisher) and clones the transactions to the Distribution Database (Distributor), this database acts as a queue for the destination database (Subscriber). Next, the Distribution Agent moves the cloned transactions that are stored in the Distribution Database to the Subscriber. The Distribution Agent can either run at scheduled intervals or continuously which offers near real-time replication of data! So for example when a user executes an UPDATE statement on one or multiple records in the publisher database, this transaction (not the data itself) is copied to the distribution database and is then also executed on the subscriber. When the Distribution Agent is set to run continuously this process runs all the time and transactions on the publisher are replicated in small batches (near real-time), when it runs on scheduled intervals it executes larger batches of transactions, but the idea is the same. Snapshot Replication This type of replication makes an initial copy of database objects that need to be replicated, this includes the schemas and the data itself. All types of replication must start with a snapshot of the database objects from the Publisher to initialize the Subscriber. Transactional replication need an initial snapshot of the replicated publisher tables/objects to run its cloned transactions on and maintain consistency. The Snapshot Agent copies the schemas of the tables that will be replicated to files that will be stored in the Snapshot Folder which is a normal folder on the file system. When all the schemas are ready, the data itself will be copied from the Publisher to the snapshot folder. The snapshot is generated as a set of bulk copy program (BCP) files. Next, the Distribution Agent moves the snapshot to the Subscriber, if necessary it applies schema changes first and copies the data itself afterwards. The application of schema changes to the Subscriber is a nice feature, when you change the schema of the Publisher with, for example, an ALTER TABLE statement, that change is propagated by default to the Subscriber(s). Merge Replication Merge replication is typically used in server-to-client environments, for example when subscribers need to receive data, make changes offline, and later synchronize changes with the Publisher and other Subscribers, like with mobile devices that need to synchronize one in a while. Because I don’t really see BI capabilities here, I will not explain this type of replication any further. Replication Services in a BI environment Transactional Replication can be very useful in BI environments. In my opinion you never want to see users to run custom (SSRS) reports or PowerPivot solutions directly on your production database, it can slow down the system and can cause deadlocks in the database which can cause errors. Transactional Replication can offer a read-only, near real-time database for reporting purposes with minimal overhead on the source system. Snapshot Replication can also be useful in BI environments, if you don’t need a near real-time copy of the database, you can choose to use this form of replication. Next to an alternative for Transactional Replication it can be used to stage data so it can be transformed and moved into the data warehousing environment afterwards. In many solutions I have seen developers create multiple SSIS packages that simply copies data from one or more source systems to a staging database that figures as source for the ETL process. The creation of these packages takes a lot of (boring) time, while Replication Services can do the same in minutes. It is possible to filter out columns and/or records and it can even apply schema changes automatically so I think it offers enough features here. I don’t know how the performance will be and if it really works as good for this purpose as I expect, but I want to try this out soon!

• 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?

• The Complementary Roles of PLM and PIM

  - by Ulf Köster

  Oracle Product Value Chain Solutions (aka Enterprise PLM Solutions) are a comprehensive set of product management solutions that work together to provide Oracle customers with a broad array of capabilities to manage all aspects of product life: innovation, design, launch, and supply chain / commercialization processes beyond the capabilities and boundaries of traditional engineering-focused Product Lifecycle Management applications. They support companies with an integrated managed view across the product value chain: From Lab to Launch, From Farm to Fork, From Concept to Product to Customer, From Product Innovation to Product Design and Product Commercialization. Product Lifecycle Management (PLM) represents a broad suite of software solutions to improve product-oriented business processes and data. PLM success stories prove that PLM helps companies improve time to market, increase product-related revenue, reduce product costs, reduce internal costs and improve product quality. As a maturing suite of enterprise solutions, PLM is still evolving to realize the promise it can provide across all facets of a business and all phases of the product lifecycle. The vision for PLM includes everything from gathering early requirements for a product through multiple stages of the product lifecycle from product design, through commercialization and eventual product retirement or replacement. In discrete or process industries, PLM is typically more focused on Product Definition as items with respect to the technical view of a material or part, including specifications, bills of material and manufacturing data. With Agile PLM, this is specifically related to capabilities addressing Product Collaboration, Governance and Compliance, Product Quality Management, Product Cost Management and Engineering Collaboration. PLM today is mainly addressing key requirements in the early product lifecycle, in engineering changes or in the “innovation cycle”, and primarily adds value related to product design, development, launch and engineering change process. In short, PLM is the master for Product Definition, wherever manufacturing takes place. Product Information Management (PIM) is a product suite that has evolved in parallel to PLM. Product Information Management (PIM) can extend the value of PLM implementations by providing complementary tools and capabilities. More relevant in the area of Product Commercialization, the vision for PIM is to manage product information throughout an enterprise and supply chain to improve product-related knowledge management, information sharing and synchronization from multiple data sources. PIM success stories have shown the ability to provide multiple benefits, with particular emphasis on reducing information complexity and information management costs. Product Information in PIM is typically treated as the commercial view of a material or part, including sales and marketing information and categorization. PIM collects information from multiple manufacturing sites and multiple suppliers into its repository, but also provides integration tools to push the information back out to the other systems, serving as an active central repository with the aim to provide a holistic view on any product sold by a company (hence the name “Product Hub”). In short, PIM is the master of commercial Product Information. So PIM is quickly becoming mandatory because of its value in optimizing multichannel selling processes and relationships with customers, as you can see from the following table: Viewpoint PLM Current State PIM Key Benefits PIM adds to PLM Product Lifecycle Primarily R&D Front end Innovation Cycle Change process Primarily commercial / transactional state of lifecycle Provides a seamless information flow from design and manufacturing through the ultimate selling and servicing of products Data Primarily focused on “item” vs. “product” data Product structures Specifications Technical information Repository for all product information. Reaches out to entire enterprise and its various silos of product information and descriptions Provides a “trusted source” of accurate product information to the internal organization and trading partners Data Lifecycle Repository for all design iterations Historical information Released, current information, with version management and time stamping Provides a single location to track and audit historical product information Communication PLM release finished product to ERP PLM is the master for Product Definition Captures information from disparate sources, including in-house data stores Recognizes the reality of today’s data “mess” across information silos Provides the ability to package product information to its audience in the desired, relevant format to meet their exacting business requirements Departmental R&D Manufacturing Quality Compliance Procurement Strategic Marketing Focus on Marketing and Sales Gathering information from other Departments, multiple sites, multiple suppliers A singular enterprise solution that leverages existing information silos and data stores Supply Chain Multi-site internal collaboration Supplier collaboration Customer collaboration Works with customers, exchanges / data pools, and trading partners to provide relevant product information packaged the way the customer desires Provides ability to provide trading partners and internal customers with information in a manner they desire, continuously Tools Data Management Collaboration Innovation Management Cleansing Synchronization Hub functions Consistent, clean and complete commercial product information The goals of both PLM and PIM, put simply, are to help companies make more profit from their products. PLM and PIM solutions can be easily added as they share some of the same goals, while coming from two different perspectives: the definition of the product and the commercialization of the product. Both can serve as a form of product “system of record”, but take different approaches to delivering value. Oracle Product Value Chain solutions offer rich new strategies for executives to collectively leverage Agile PLM, Product Data Hub, together with Enterprise Data Quality for Products, and other industry leading Oracle applications to achieve further incremental value, like Oracle Innovation Management. This is unique on the market today.

• Some New .NET Toys (Repost)

  - by Kevin Grossnicklaus

  Last week I was fortunate enough to spend time in Redmond on Microsoft’s campus for the 2011 Microsoft MVP Summit. It was great to hang out with a number of old friends and get the opportunity to talk tech with the various product teams up at Microsoft. The weather wasn’t exactly sunny but Microsoft always does a great job with the Summit and everyone had a blast (heck, I even got to run the bases at SafeCo field) While much of what we saw is covered under NDA, there a ton of great things in the pipeline from Microsoft and many things that are already available (or just became so) that I wasn’t necessarily aware of. The purpose of this post is to share some of the info I learned on resources and tools available to .NET developers today. Please let me know if you have any questions (or if you know of something else cool which might benefit others). Enjoy! Visual Studio 2010 SP1 Microsoft has issued the RTM release of Visual Studio 2010 SP1. You can download the full SP1 on MSDN as of today (March 10th to the general public) and take advantage of such things as: Silverlight 4 is included in the box (as opposed to a separate install) Silverlight 4 Profiling WCF RIA Services SP1 Intellitrace for 64-bit and SharePoint ASP.NET now easily supports IIS Express and SQL CE Want a description of all that’s new beyond the above biased list (which arguably only contains items I think are important)? Check out this KB article. Portable Library Tools CTP Without much fanfare Microsoft has released a CTP of a new add-in to Visual Studio 2010 which simplifies code sharing between projects targeting different runtimes (i.e. Silverlight, WPF, Win7 Phone, XBox). With this Add-In installed you can add a new project of type “Portable Library” and specify which platforms you wish to target. Once that is done, any code added to this library will be limited to use only features which are common to all selected frameworks. Other projects can now reference this portable library and be provided assemblies custom built to their environment. This greatly simplifies the current process of sharing linked files between platforms like WPF and Silverlight. You can find out more about this CTP and how it works on this great blog post. Visual Studio Async CTP Microsoft has also released a CTP of a set of language and framework enhancements to provide a much more powerful asynchronous programming model. Due to the focus on async programming in all types of platforms (and it being the ONLY option in Silverlight and Win7 phone) a move towards a simpler and more understandable model is always a good thing. This CTP (called Visual Studio Async CTP) can be downloaded here. You can read more about this CTP on this blog post. MSDN Code Samples Gallery Microsoft has also launched new code samples gallery on their MSDN site: http://code.msdn.microsoft.com/. This site allows you to easily search for small samples of code related to a particular technology or platform. If a sample of code you are looking for is not found, you can request one via the site and other developers can see your request and provide a sample to the site to suit your needs. You can also peruse requested samples and, if you find a scenario where you can provide value, upload your own sample for the benefit of others. Samples are packaged into the VS .vsix format and include any necessary references/dependencies. By using .vsix as the deployment mechanism, as samples are installed from the site they are kept in your Visual Studio 2010 Samples Gallery and kept for your future reference. If you get a chance, check out the site and see how it is done. Although a somewhat simple concept, I was very impressed with their implementation and the way they went about trying to suit a need. I’ll definitely be looking there in the future as need something or want to share something. MSDN Search Capabilities Another item I learned recently and was not aware of (that might seem trivial to some) is the power of the MSDN site’s search capabilities. Between the Code Samples Gallery described above and the search enhancements on MSDN, Microsoft is definitely investing in their platform to help provide developers of all skill levels the tools and resources they need to be successful. What do I mean by the MSDN search capability and why should you care? If you go to the MSDN home page (http://msdn.microsoft.com) and use the “Search MSDN with Big” box at the very top of the page you will see some very interesting results. First, the search actually doesn’t just search the MSDN library it searches: MSDN Library All Microsoft Blogs CodePlex StackOverflow Downloads MSDN Magazine Support Knowledgebase (I’m not sure it even ends there but the above are all I know of) Beyond just searching all the above locations, the results are formatted very nicely to give some contextual information based on where the result came from. For example, if a keyword search returned results from CodePlex, each row in the search results screen would include a large amount of information specific to CodePlex such as: Looking at the above results immediately tells you everything from the page views to the CodePlex ratings. All in all, knowing that this much information is indexed and available from a single search location will lead me to utilize this as one of my initial searches for development information.

• My History with Agile

  - by Robert May

  I’m going to write my history with Agile here.  That way, in future posts, I can refer back to it, instead of typing it out in the post that contains information you may actually want to read.  Note that I’m actually a pretty senior developer, and do lots of technical interviews.  I’m an Agile fan because of the difference it makes in peoples lives and the improvement in quality it brings, and I’ll sacrifice my technological advance to help teams. Management History I started management pretty early in my career, starting with the first job that I ever had.  I actually do NOT have a CS or similar degree.  I have a Bachelor’s of Business Administration with an emphasis in Computer Information Systems. My first management gigs were around call center work and were very schedule oriented.  I didn’t understand the true value of teams, and I’m ashamed to admit, I actually installed a fingerprint scanner as a time clock in this job.  I shudder to think of the impact that I had on the team spirit.  I didn’t even trust them enough to fill out their time cards correctly.  How sad. I was managing nearly 100 people in this position, with the help of a great set of subordinates. I did try to come up with reward programs for the team, but again, didn’t understand the concept of team, so instead of letting the team determine how the rewards should work, I mandated from on high, which isn’t a good thing. I was told that I wasn’t the type that would be a good manager by people whom I respected a lot.  They said it because I was a computer geek, since they don’t understand good management either, but in retrospect, they were right about me then.  I was too green. After my first job, I went on to other jobs and with the exception of one job, I’ve managed people at them all.  The rest of the management story is important for understanding agile, so I’ll save it for my next post. Technical History I’ve been in software development for many, many years.  I technically started programming on a commodore 64 in basic.  I didn’t know that I was programming, but I was sure having fun.  That was followed by batch files, Gorilla hacking (I always had to win), WordPerfect Macro programming and other things that taught me the basics. My first “real” job was with a telephone company, and that’s where I made my first database application in DataEase, wrote my first VBA app and started using real programming tools, like turbo pascal, vb3-vb5, and semi-real tools like RPG and VisualRPG.  I wrote my first web page in 1994, and built my first data driven web page in 1995 using perlDB.  You really can do anything with Perl.  At this time, I also started a Linux based internet service provider that is still in operation today.  One of the people I worked with is now a Microsoft employee building and designing frameworks you probably know well.  Smart guy.  I also built my first ASP applications connecting to Sql Server 6.5, setup Exchange 5.5 for the company, and many other system administration stuff.  I’m a programmer by choice, mostly because I don’t really like PC support. From there, I went on to a large state agency.  I got to see and maintain true waterfall projects.  5 years of maintaining the 200 VB COM+ (MTS, actually) dlls that were used to calculate a single number is a long time.  That was all Microsoft DNS technologies.  SQL Server and VB6 were the tools of choice, although .net started to be a factor near the end of employment.  I did some heavy XML work at this job and even wrote an XSD parser and validator in VB6 that was a shim until MSXML 3.0 came out.  Prior to 3.0, XSD’s weren’t supported, and I didn’t want to write DTDs. Ironically, jobs after this were more generic.  I pretty much settled in on the .net framework and revisions of it.  Lots of WPF, some silverlight, lots of ASP.NET, some SQL Azure, lots of SQL Server, some Oracle, but I don’t think that I was as passionate about development and technologies.  I was more into the management of development.  I like people.

• Oracle: Addressing Information Overload in Factory Automation

  - by [email protected]

   ORACLE's Stephen Slade has written about addressing information overload on the factory floor.  According to Slade, today's automated processes create large amounts of valuable data, but only a small percentage remains actionable.Oracle claims information overload can cost financially, as companies struggle to store and collect reams of data needed to identify embedded trends, while producing manual reports to meet quality standards, regulatory requirements and general reporting goals.Increasing scrutiny of new requirements and standards add to the need to find new ways to process data. Many companies are now using analytical engines to contextualise data into 'actionable information'. Oracle claims factories need to seriously address their data collection, audit trail and records retention processes. By organising their data, factories can maximise outcomes from excellence and contuinuous improvement programs, and gain visibility into costs int the supply chain.Analytics tools and technologies such as Business Intelligence (BI), Enterprise Manufacturing Intelligence (EMI) and Manufacturing Operations Centers (MOC) can help consolidate, contextual and distribute information.   FULL ARICLE:  http://www.myfen.com.au/news/oracle--addressing-information-overload-in-factory

• Benefits of PerformancePoint Services Using SharePoint Server 2010

  - by Wayne

  What is PerformancePoint Services? Most of the time it happens that the metrics that make up your key performance indicators are not simple values from a data source. In SharePoint Server 2007 PerformancePoint Services, you could create two kinds of KPI metrics: Simple single value metrics from any supported data source or Complex multiple value metrics from a single Analysis Services data source using MDX. Now things are even easier with Performance Point Services in SharePoint 2010. Let us check what is it? PerformancePoint Services in SharePoint Server 2010 is a performance management service that you can use to monitor and analyze your business. By providing flexible, easy-to-use tools for building dashboards, scorecards, reports, and key performance indicators (KPIs), PerformancePoint Services can help everyone across an organization make informed business decisions that align with companywide objectives and strategy. Scorecards, dashboards, and KPIs help drive accountability. Integrated analytics help employees move quickly from monitoring information to analyzing it and, when appropriate, sharing it throughout the organization. Prior to the addition of PerformancePoint Services to SharePoint Server, Microsoft Office PerformancePoint Server 2007 functioned as a standalone server. Now PerformancePoint functionality is available as an integrated part of the SharePoint Server Enterprise license, as is the case with Excel Services in Microsoft SharePoint Server 2010. The popular features of earlier versions of PerformancePoint Services are preserved along with numerous enhancements and additional functionality. New PerformancePoint Services features PerformancePoint Services now can utilize SharePoint Server scalability, collaboration, backup and recovery, and disaster recovery capabilities. Dashboards and dashboard items are stored and secured within SharePoint lists and libraries, providing you with a single security and repository framework. New features and enhancements of SharePoint 2010 PerformancePoint Services • With PerformancePoint Services, functioning as a service in SharePoint Server, dashboards and dashboard items are stored and secured within SharePoint lists and libraries, providing you with a single security and repository framework. The new architecture also takes advantage of SharePoint Server scalability, collaboration, backup and recovery, and disaster recovery capabilities. You also can include and link PerformancePoint Services Web Parts with other SharePoint Server Web Parts on the same page. The new architecture also streamlines security models that simplify access to report data. • The Decomposition Tree is a new visualization report type available in PerformancePoint Services. You can use it to quickly and visually break down higher-level data values from a multi-dimensional data set to understand the driving forces behind those values. The Decomposition Tree is available in scorecards and analytic reports and ultimately in dashboards. • You can access more detailed business information with improved scorecards. Scorecards have been enhanced to make it easy for you to drill down and quickly access more detailed information. PerformancePoint scorecards also offer more flexible layout options, dynamic hierarchies, and calculated KPI features. Using this enhanced functionality, you can now create custom metrics that use multiple data sources. You can also sort, filter, and view variances between actual and target values to help you identify concerns or risks. • Better Time Intelligence filtering capabilities that you can use to create and use dynamic time filters that are always up to date. Other improved filters improve the ability for dashboard users to quickly focus in on information that is most relevant. • Ability to include and link PerformancePoint Services Web Parts together with other PerformancePoint Services Web parts on the same page. • Easier to author and publish dashboard items by using Dashboard Designer. • SQL Server Analysis Services 2008 support. • Increased support for accessibility compliance in individual reports and scorecards. • The KPI Details report is a new report type that displays contextually relevant information about KPIs, metrics, rows, columns, and cells within a scorecard. The KPI Details report works as a Web part that links to a scorecard or individual KPI to show relevant metadata to the end user in SharePoint Server. This Web part can be added to PerformancePoint dashboards or any SharePoint Server page. • Create analytics reports to better understand underlying business forces behind the results. Analytic reports have been enhanced to support value filtering, new chart types, and server-based conditional formatting. To conclude, PerformancePoint Services, by becoming tightly integrated with SharePoint Server 2010, takes advantage of many enterprise-level SharePoint Server 2010 features. Unfortunately, SharePoint Foundation 2010 doesn’t include this feature. There are still many choices in SharePoint family of products that include SharePoint Server 2010, SharePoint Foundation, SharePoint Server 2007 and associated free SharePoint web parts and templates.

• ORA-4030 Troubleshooting

  - by [email protected]

  QUICKLINK: Note 399497.1 FAQ ORA-4030 Note 1088087.1 : ORA-4030 Diagnostic Tools [Video]   Have you observed an ORA-0430 error reported in your alert log? ORA-4030 errors are raised when memory or resources are requested from the Operating System and the Operating System is unable to provide the memory or resources.   The arguments included with the ORA-4030 are often important to narrowing down the problem. For more specifics on the ORA-4030 error and scenarios that lead to this problem, see Note 399497.1 FAQ ORA-4030.   Looking for the best way to diagnose? There are several available diagnostic tools (error tracing, 11g Diagnosibility, OCM, Process Memory Guides, RDA, OSW, diagnostic scripts) that collectively can prove powerful for identifying the cause of the ORA-4030.    Error Tracing   The ORA-4030 error usually occurs on the client workstation and for this reason, a trace file and alert log entry may not have been generated on the server side.  It may be necessary to add additional tracing events to get initial diagnostics on the problem. To setup tracing to trap the ORA-4030, on the server use the following in SQLPlus: alter system set events '4030 trace name heapdump level 536870917;name errorstack level 3';Once the error reoccurs with the event set, you can turn off  tracing using the following command in SQLPlus:alter system set events '4030 trace name context off; name context off';NOTE:   See more diagnostics information to collect in Note 399497.1  11g DiagnosibilityStarting with Oracle Database 11g Release 1, the Diagnosability infrastructure was introduced which places traces and core files into a location controlled by the DIAGNOSTIC_DEST initialization parameter when an incident, such as an ORA-4030 occurs.  For earlier versions, the trace file will be written to either USER_DUMP_DEST (if the error was caught in a user process) or BACKGROUND_DUMP_DEST (if the error was caught in a background process like PMON or SMON). The trace file may contain vital information about what led to the error condition.    Note 443529.1 11g Quick Steps to Package and Send Critical Error Diagnostic Informationto Support[Video]  Oracle Configuration Manager (OCM) Oracle Configuration Manager (OCM) works with My Oracle Support to enable proactive support capability that helps you organize, collect and manage your Oracle configurations.

• Big Data – Evolution of Big Data – Day 3 of 21

  - by Pinal Dave

  In yesterday’s blog post we answered what is the Big Data. Today we will understand why and how the evolution of Big Data has happened. Though the answer is very simple, I would like to tell it in the form of a history lesson. Data in Flat File In earlier days data was stored in the flat file and there was no structure in the flat file.  If any data has to be retrieved from the flat file it was a project by itself. There was no possibility of retrieving the data efficiently and data integrity has been just a term discussed without any modeling or structure around. Database residing in the flat file had more issues than we would like to discuss in today’s world. It was more like a nightmare when there was any data processing involved in the application. Though, applications developed at that time were also not that advanced the need of the data was always there and there was always need of proper data management. Edgar F Codd and 12 Rules Edgar Frank Codd was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases. He presented 12 rules for the Relational Database and suddenly the chaotic world of the database seems to see discipline in the rules. Relational Database was a promising land for all the unstructured database users. Relational Database brought into the relationship between data as well improved the performance of the data retrieval. Database world had immediately seen a major transformation and every single vendors and database users suddenly started to adopt the relational database models. Relational Database Management Systems Since Edgar F Codd proposed 12 rules for the RBDMS there were many different vendors who started them to build applications and tools to support the relationship between database. This was indeed a learning curve for many of the developer who had never worked before with the modeling of the database. However, as time passed by pretty much everybody accepted the relationship of the database and started to evolve product which performs its best with the boundaries of the RDBMS concepts. This was the best era for the databases and it gave the world extreme experts as well as some of the best products. The Entity Relationship model was also evolved at the same time. In software engineering, an Entity–relationship model (ER model) is a data model for describing a database in an abstract way. Enormous Data Growth Well, everything was going fine with the RDBMS in the database world. As there were no major challenges the adoption of the RDBMS applications and tools was pretty much universal. There was a race at times to make the developer’s life much easier with the RDBMS management tools. Due to the extreme popularity and easy to use system pretty much every data was stored in the RDBMS system. New age applications were built and social media took the world by the storm. Every organizations was feeling pressure to provide the best experience for their users based the data they had with them. While this was all going on at the same time data was growing pretty much every organization and application. Data Warehousing The enormous data growth now presented a big challenge for the organizations who wanted to build intelligent systems based on the data and provide near real time superior user experience to their customers. Various organizations immediately start building data warehousing solutions where the data was stored and processed. The trend of the business intelligence becomes the need of everyday. Data was received from the transaction system and overnight was processed to build intelligent reports from it. Though this is a great solution it has its own set of challenges. The relational database model and data warehousing concepts are all built with keeping traditional relational database modeling in the mind and it still has many challenges when unstructured data was present. Interesting Challenge Every organization had expertise to manage structured data but the world had already changed to unstructured data. There was intelligence in the videos, photos, SMS, text, social media messages and various other data sources. All of these needed to now bring to a single platform and build a uniform system which does what businesses need. The way we do business has also been changed. There was a time when user only got the features what technology supported, however, now users ask for the feature and technology is built to support the same. The need of the real time intelligence from the fast paced data flow is now becoming a necessity. Large amount (Volume) of difference (Variety) of high speed data (Velocity) is the properties of the data. The traditional database system has limits to resolve the challenges this new kind of the data presents. Hence the need of the Big Data Science. We need innovation in how we handle and manage data. We need creative ways to capture data and present to users. Big Data is Reality! Tomorrow In tomorrow’s blog post we will try to answer discuss Basics of Big Data Architecture.
