  • If some standards apply when "it depends" then should I stick with custom approaches?

    - by Travis J
    If I have an unconventional approach which works better than the industry standard, should I just stick with it even though in principal it violates those standards? What I am talking about is referential integrity for relational database management systems. The standard for enforcing referential integrity is to CASCADE delete. In practice, this is just not going to work all the time. In my current case, it does not. The alternative suggested is to either change the reference to NULL, DEFAULT, or just to take NO ACTION - usually in the form of a "soft delete". I am all about enforcing referential integrity. Love it. However, sometimes it just does not fully apply to use all the standards in practice. My approach has been to slightly abandon a small part of one of those practices which is the part about leaving "hanging references" around. Oops. The trade off is plentiful in this situation I believe. Instead of having deprecated data in the production database, a splattering of "soft delete" logic all across my controllers (and views sometimes depending on how far down the chain the soft delete occurred), and the prospect of queries taking longer and longer - instead of all that - I now have a recycle bin and centralized logic. The only tradeoff is that I must explicitly manage the possibility of "hanging references" which can be done through generics with one class. Any thoughts?

  • SQL SERVER – SQL Server Performance: Indexing Basics – SQL in Sixty Seconds #006 – Video

    - by pinaldave
    A DBA’s role is critical, because a production environment has to run 24×7, hence maintenance, trouble shooting, and quick resolutions are the need of the hour.  The first baby step into any performance tuning exercise in SQL Server involves creating, analyzing, and maintaining indexes. Though we have learnt indexing concepts from our college days, indexing implementation inside SQL Server can vary.  Understanding this behavior and designing our applications appropriately will make sure the application is performed to its highest potential. Vinod Kumar and myself we often thought about this and realized that practical understanding of the indexes is very important. One can not master every single aspects of the index. However there are some minimum expertise one should gain if performance is one of the concern. More on Indexes: SQL Index SQL Performance I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can. Here is the interview of Vinod Kumar by myself.

  • SQL SERVER – Table Variables and Transactions – SQL in Sixty Seconds #007 – Video

    - by pinaldave
    Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Misconception and Resolution. Quite often I have seen people getting confused with certain behavior of the T-SQL. They expect SQL to behave certain way and SQL Server behave differently. This kind of issue often creates confusion and frustration. Sometime I have seen them also confusing it with bug and submitting the bug, where reality is totally different. Similar concept which are going to see today. I have seen quite commonly developer assuming that table various will be rolled back when transaction is rolled back. This sixty seconds video describes that table various are not rolled back when transactions are rolled back.

  • SQL SERVER – Right Aligning Numerics in SQL Server Management Studio (SSMS)

    - by pinaldave
    SQL Server Management Studio is my most favorite tool and the comfort it provides to user is sometime very amazing. Recently I was retrieving numeric data in SSMS and I found it is very difficult to read them as they were all right aligned. Please pay attention to following image, you will notice that it is not easier to read the digits as we are used to read the numbers which are right aligned. I immediately thought before I go for any other tricks I should check the query properties. I right clicked on query properties and I found following option. I checked option Right align numeric values and it just worked fine. Do you have any other similar tricks which do you practice often. I prefer to also include column headers in the result set as it gives me proper perspective of which column I have selected. Sometime little tips like this helps a lot in productivity, I encourage you to share your tips. I will publish it with due credit.

  • SQL SERVER – Cardinality Estimation and Performance – SQL in Sixty Seconds #072

    - by Pinal Dave
    Yesterday I wrote blog post based on my latest Pluralsight course on learning SQL Server 2014. I discussed newly introduced cardinality estimation in SQL Server 2014 and how it improves the performance of the query. The cardinality estimation logic is responsible for quality of query plans and majorly responsible for improving performance for any query. This logic was not updated for quite a while, but in the latest version of SQL Server 2104 this logic is re-designed. The new logic now incorporates various assumptions and algorithms of OLTP and warehousing workload. I hope my earlier blog post clearly explained how new cardinality estimation logic improves performance. If not, I suggest you watch following quick video where I explain this concept in extremely simple words. You can download the code used in this course from Simple Demo of New Cardinality Estimation Features of SQL Server 2014. Action Item Here are the blog posts I have previously written. You can read it over here: Simple Demo of New Cardinality Estimation Features of SQL Server 2014 Pluralsight Course You can subscribe to my YouTube Channel for frequent updates.

  • OpenGL - Stack overflow if I do, Stack underflow if I don't!

    - by Wayne Werner
    Hi, I'm in a multimedia class in college, and we're "learning" OpenGL as part of the class. I'm trying to figure out how the OpenGL camera vs. modelview works, and so I found this example. I'm trying to port the example to Python using the OpenGL bindings - it starts up OpenGL much faster, so for testing purposes it's a lot nicer - but I keep running into a stack overflow error with the glPushMatrix in this code: def cube(): for x in xrange(10): glPushMatrix() glTranslated(-positionx[x + 1] * 10, 0, -positionz[x + 1] * 10); #translate the cube glutSolidCube(2); #draw the cube glPopMatrix(); According to this reference, that happens when the matrix stack is full. So I thought, "well, if it's full, let me just pop the matrix off the top of the stack, and there will be room". I modified the code to: def cube(): glPopMatrix() for x in xrange(10): glPushMatrix() glTranslated(-positionx[x + 1] * 10, 0, -positionz[x + 1] * 10); #translate the cube glutSolidCube(2); #draw the cube glPopMatrix(); And now I get a buffer underflow error - which apparently happens when the stack has only one matrix. So am I just waaay off base in my understanding? Or is there some way to increase the matrix stack size? Also, if anyone has some good (online) references (examples, etc.) for understanding how the camera/model matrices work together, I would sincerely appreciate them! Thanks!

  • Use a Free Utility to Create Multiple Virtual Desktops in Windows

    - by Lori Kaufman
    If you’ve used Linux, you’re probably familiar with the virtual desktop feature. It provides a convenient way to organize programs and folders open on your desktop. You can switch among multiple desktops and have different programs and folders open on each one. However, virtual desktops is a feature missing in Windows. There are many third-party options for adding virtual desktops to Windows, including one called Dexpot, which we have covered previously. Dexpot is free, but only for private use. Companies, public institutions, non-profit organizations, and even freelancers and self-employed people must buy the program. We found another virtual desktop tool that is completely free for everyone to use, called mDesktop. It’s a lightweight, open source program that allows you to switch among multiple desktops using hot keys and specify open programs or folders to be active on all desktops. You can use mDesktop to group related programs or to work on different projects on separate desktops. mDesktop is portable and does not need to be installed. Simply extract the .zip file you downloaded (see the link at the end of this article) and double-click the mDesktop.exe file.

  • Transitioning to Transaction Base

    - by Glen McCallum
    I was actually hired at Oracle Health Sciences to work on the HTB application. Long story short, when HL7 version 3 was relatively new ... Canada made an initial sprint at adoption. Since then progress has slowed. I was part of that initial adoption and learned a lot about the Reference Information Model. At that time we worked mostly with CDA R2 Level 3 (fully coded/ structured xml) documents.HTB is a HL7 v3 RIM-based repository. Love it or hate it, the product is unique in the market place. One of the advantages is the flexibility of the model. You can aggregate information from literally any source system without any HTB data model modification and then use that data in a semantically meaningful way. That's extremely powerful.There is a minor speed bump getting up to speed with HL7 v3, there's no doubt about that. I believe that is why Oracle recruited me from Canada originally - so I could have a running start at HTB. In the near future I'm looking forward to an application deep dive with John Hatem.

  • SQL SERVER – Copy Column Headers from Resultset – SQL in Sixty Seconds #026 – Video

    - by pinaldave
    SQL Server Management Studio returns results in Grid View, Text View and to the file. When we copy results from Grid View to Excel there is a common complaint that the column  header displayed in resultset is not copied to the Excel. I often spend time in performance tuning databases and I run many DMV’s in SSMS to get a quick view of the server. In my case it is almost certain that I need all the time column headers when I copy my data to excel or any other place. SQL Server Management Studio have two different ways to do this. Method 1: Ad-hoc When result is rendered you can right click on the resultset and click on Copy Header. This will copy the headers along with the resultset. Additionally, you can use the shortcut key CTRL+SHIFT+C for coping column headers along with the resultset. Method 2: Option Setting at SSMS level This is SSMS level settings and I kept this option always selected as I often need the column headers when I select the resultset. Go Tools >> Options >> Query Results >> SQL Server >> Results to Grid >> Check the Box “Include column header when copying or saving the results.” Both of the methods are discussed in following SQL in Sixty Seconds Video. Here is the code used in the video.

  • TechEd 2012: Office, SharePoint And More Office

    - by Tim Murphy
    I haven’t spent any time looking at Office 365 up to this point.  I met Donovan Follette on the flight down from Chicago.  I also got to spend some time discussing the product offerings with him at the TechExpo and that sealed my decision to attend this session. The main actor of his presentation is the BCS – Business Connectivity Services. He explained that while this feature has existed in on-site SharePoint it is a valuable new addition to Office 365 SharePoint Online.  If you aren’t familiar with the BCS, it allows you to leverage non-SharePoint enterprise data source from SharePoint.  The greatest benefactor is the end users who can leverage the data using a variety of Office products and more.  The one thing I haven’t shaken my skepticism of is the use of SharePoint Designer which Donovan used to create a WCF service.  It is mostly my tendency to try to create solutions that can be managed through the whole application life cycle.  It the past migrating through test environments has been near impossible with anything other than content created by SharePiont Designer. There is a lot of end user power here.  The biggest consideration I think you need to examine when reaching from you enterprise LOB data stores out to an online service and back is that you are going to take a performance hit.  This means that you have to be very aware of how you configure these integrated self serve solutions.  As a rule make sure you are using the right tool for the right situation. I appreciated that he showed both no code and code solutions for the consumer of the LOB data.  I came out of this session much better informed about the possibilities around this product. del.icio.us Tags: Office 365,SharePoint Online,TechEd,TechEd 2012

  • Dutch ACEs SOA Partner Community Award Celebration

    - by JuergenKress
    When you win you need to celebrate. This was the line of thinking when I found out that I was part of a group that won the Oracle SOA Community Country Award. Well – thinking about a party is one thing, preparing it and finally having the small party is something completely different. It starts with finding a date that would be suitable for the majority of invited people. As you can imagine the SOA ACEs and ACE Directors have a busy life, that takes them places. Alongside that they are engaged with customers who want to squeeze every bit of knowledge out of them. So everybody is pretty busy (that’s what makes you an ACE). After some deliberation (and checks of international Oracle events, Trip-it, blogs and tweets) a date was chosen. Meeting on a Friday evening for some drinks is probably not a Dutch-only activity. But as some of the ACEs are self-employed they miss the companies around them to organize such events. Come the day a turn-out of almost 50% was great – although I expected some more folks . This was mainly due to some illness and work overload. Luckily the mini-party got going, (alcoholic) beverages were consumed, food was appreciated, a decent picture was made (see below) and all had a good chat and hopefully a good time. (Above from left to right: Eric Elzinga, Andreas Chatziantoniou, Mike van Aalst, Edwin Biemond) All in all a nice evening and certainly a "meeting" which can be repeated.  For the full article please visit Andreas's blog Want to organize a local SOA & BPM community?

  • SQL SERVER – Database in RESTORING State for Long Time

    - by Pinal Dave
    A very interesting question I received the other day. “Our database has been in restoring stage for a long time. We have already restored all the necessary files there. After restoring the files we are expecting that  the database will be in operational mode, however, it is continuously in the restoring mode. Any suggestion?” The question is very common. I sent user follow up emails to understand what is actually going on with the user. I realized after restoring their bak files and log files their database was in the restoring state because they had not restored the latest log file with RECOVERY options. As they had completed all the database restore sequence (bak and log in order), the real need for them was to recover the database from norecovery state. User can restore log files till the database is no recovery mode. If the database is recovered it will be in operation and it can continue database operation. If the database has another operations we cannot restore further log as the chain of the log file after the database is recovered is meaningless. This is the reason why the database has to be norecovery state when it is restored. There are three different ways to recover the database. 1) Recover the database manually with following command. RESTORE DATABASE database_name WITH RECOVERY 2) Recover the database with the last log file. RESTORE LOG database_name FROM backup_device WITH RECOVERY 3) Recover the database when bak is restored RESTORE DATABASE database_name FROM backup_device WITH RECOVERY To understand how the backup restores timeline works read Backup Timeline and Understanding of Database Restore Process in Full Recovery Model.

  • Gain Total Control of Systems running Oracle Linux

    - by Anand Akela
    Oracle Linux is the best Linux for enterprise computing needs and Oracle Enterprise Manager enables enterprises to gain total control over systems running Oracle Linux. Linux Management functionality is available as part of Oracle Enterprise Manager 12c and is available to Oracle Linux Basic and Premier Support customers at no cost. The solution provides an integrated and cost-effective solution for complete Linux systems lifecycle management and delivers comprehensive provisioning, patching, monitoring, and administration capabilities via a single, web-based user interface thus significantly reducing the complexity and cost associated with managing Linux operating system environments. Many enterprises are transforming their IT infrastructure from multiple independent datacenters to an Infrastructure-as-a-Service (IaaS) model, in which shared pools of compute and storage are made available to end-users on a self-service basis. While providing significant improvements when implemented properly, this strategy introduces change and complexity at a time when datacenters are already understaffed and overburdened. To aid in this transformation, IT managers need the proper tools to help them provide the array of IT capabilities required throughout the organization without stretching their staff and budget to the limit. Oracle Enterprise Manager 12c offers  the advanced capabilities to enable IT departments and end-users to take advantage of many benefits and cost savings of IaaS. Oracle Enterprise Manager Ops Center 12c addresses this challenge with a converged approach that integrates systems management across the infrastructure stack, helping organizations to streamline operations, increase productivity, and reduce system downtime.  You can see the Linux management functionality in action by watching the latest integrated Linux management demo .

    LinqPad as we all know has been a wonderful tool for running ad-hoc queries. With Azure Table storage in picture LinqPad was no longer in picture and we shifted focus to Cloud Storage Studio only to realize the limited and strange querying capabilities of CSS. With some tweaking to Linqpad we can get the comfortable old shoe of ad-hoc queries with LinqPad in the Azure Table storage. Steps: 1. Start LinqPad 2. Right Click in the query window and select “Query Properties” 3. In The Additional References add reference to Microsoft.WindowsAzure.StorageClient, System.Data.Services.Client.dll and the assembly containing the implementation of the DataServiceContext class tied to the Azure table storage. 4. In the additional namespace imports import the same three namespaces mentioned above. 5. Then we need to provide following details. a. Table storage account name and shared key. b. DataServiceContext implementing class in your code. c. A LINQ query. e.x. var storageAccountName = "myStorageAccount";  // Enter valid storage account name var storageSharedKey = "mysharedKey"; // Enter valid storage account shared key var uri = new System.Uri("http://table.core.windows.net/"); var storageAccountInfo = new CloudStorageAccount(new StorageCredentialsAccountKey(storageAccountName, storageSharedKey), false); var serviceContext = new TweetPollDataServiceContext(storageAccountInfo); // Specify the DataServiceContext implementation // The query var query = from row in serviceContext.Table select row;         query.Dump(); Sarang, K

  • SQL SERVER – A Funny Cartoon on Index

    - by pinaldave
    Performance Tuning has been my favorite subject and I have done it for many years now. Today I will list one of the most common conversation about Index I have heard in my life. Every single time, I am at consultation for performance tuning I hear following conversation among various team members. I want to ask you, does this kind of conversation happens in your organization? Any way, If you think Index solves all of your performance problem I think it is not true. There are many other reason one has to consider along with Indexes. For example I consider following various topic one need to understand for performance tuning. ?Logical Query Processing ?Efficient Join Techniques ?Query Tuning Considerations ?Avoiding Common Performance Tuning Issues Statistics and Best Practices ?TempDB Tuning ?Hardware Planning ?Understanding Query Processor ?Using SQL Server 2005 and 2008 Updated Feature Sets ?CPU, Memory, I/O Bottleneck Index Tuning (of course) ?Many more… Well, I have written this blog thinking I will keep this blog post a bit easy and not load up. I will in future discuss about other performance tuning concepts. Let me know what do you think about the cartoon I made.

  • Computer Science Degree or Computer Engineering Degree?

    - by Paul
    Hello everyone, I'm 23 years old living in Italy and this year I will be getting my high school diploma. I'm interested in pursuing a collage degree and work in the IT field. At the moment I'm self teaching myself Java (I also know python, html, css and mysql). I'm also learning about algorithms and OO design. I'm curious how important a college degree is for me, considering my age and if there is a big difference between computer science and computer engineer. There is a computer science university where I currently live but not a computer engineer one. For some reason universities that offer computer engineering courses are only in bigger cities such as Milan, Bologna, Roma. Cost wise, it would be cheaper for me to study near home at a computer science school. Career wise, would a computer engineering university offer me more work opportunities instead of a computer science degree ? Is it easier transiting from CS to CEN or vice-versa? I'm not exactly sure what type of job I want to pursue in the future since I'm still a bit undecided but definitely not system/network administrator, database administrator, game developer.

  • Windows 7 - Ubuntu 10.10 Dual Boot Partitioning Recommendation for HP Laptop OEM

    - by Denja
    Hi Linux Community, After been temporary impressed with the newb Windows 7 and after intensly using it I find my self struggling with the ever slow and buggy windows OS once again. It's Time to go with the Ubuntu/Linux way for a better and faster tomorrow. Unfortunately in my country most Users/Business use Windows based Systems. As a Computer technician i want to learn and use both Systems and possibly introduce New users to more affordable Linux Based Systems. For now I want to create dual-boot or even triple boot layouts on my laptop machine Here's the layout in use now: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I want to make. * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows data partition (user files) NTFS - 60GB(Extended or Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Primary)(sda3) * Linux swap swap- RAM size, 3GB (sda4) * Linux home Ext4- 164,9GB (Extended)(sda5) Question 1: Is the layout that i want to make correct as the Primary and Extended Partition concerns ? Question 2: Can I definitely get rid of SYSTEM Boot loader of windows? Question 3: If I get rid of HP_TOOLS and RECOVERY partition will it be a problem? Question 4: Based on my layout what is your suggestion for a Triple Boot layout for OSX or Puppy Linux? Thank you in advance for your advises and suggestions.

  • SQL SERVER – Reset SA Password – SQL in Sixty Seconds #066

    - by Pinal Dave
    It has been quite a long time since I posted SQL in Sixty Seconds Video. Here we are back with the new video. One of the most popular question, I often receive is very similar to following: “How do I reset the password for SA username?” “I have forgotten the SA password, what should I do?” “Our DBA just left the job and now noone knows how to reset the SA password. Please help.” Solution Honestly, it is pretty simple to reset the password for SA username. You just have to login to the system where your SQL Server is installed. Open SQL Server Management Studio and login with the help of Windows Authentication. As local system is the admin of the SQL Server, you will get access with administration privileges. Now, open the database, expand Security >> Login folder and right click over SA username. Now, it will bring up the screen where you can change the password for SA. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password. You can read it over here:  SQL SERVER – Forgot the Password of Username SA Change Password of SA Login Using Management Studio You can subscribe to my YouTube Channel for frequent updates.
