  • Difference between Detach/Attach and Restore/BackUp a DB

    - by SAMIR BHOGAYTA
    Transact-SQL BACKUP/RESTORE is the normal method for database backup and recovery. Databases can be backed up while online. The backup file size is usually smaller than the database files since only used pages are backed up. Also, in the FULL or BULK_LOGGED recovery model, you can reduce potential data loss by performing transaction log backups. Detaching a database removes the database from SQL Server while leaving the physical database files intact. This allows you to rename or move the physical files and then re-attach. Although one could perform cold backups using this technique, detach/attach isn't really intended to be used as a backup/recovery process. Commonly it is recommended that you use BACKUP/RESTORE for disaster recovery (DR) scenario and copying data from one location to another. But this is not absolute, sometimes for a very large database, if you want to move it from one location to another, backup/restore process may spend a lot of time which you do not like, in this case, detaching/attaching a database is a better way since you can attach a workable database very fast. But you need to aware that detaching a database will bring it offline for a short time and detaching/attaching does not provide DR function. For more information about detaching and attaching databases, you can refer to: Detaching and Attaching Databases http://technet.microsoft.com/en-us/library/ms190794.aspx

  • Does waterfall require code complete before QA steps in?

    - by P.Brian.Mackey
    The process used at a certain company consists of: Create a layout according to some designs made in a web page design tool. (CSS, html) Requirements come in with "functional requirements". These consist of 100's of lines of business directions. E.G. Create a Table on page X. Column1 has numeric data. Column1 is the client code. Column2 is a string...etc. Write code to meet all functional requirements. When all code is checked in, send to QA (which is the BA that wrote the requirements) for inspection, bug finds and change requests. Punt back to developer with a list of X bugs and Y change requests. While bug finds or change requests 0 go to step 4. The agile development environments I have worked in allow, if not demand, early QA inspection and early user acceptance. So, pieces of the program can be refined and redefined before the entire application is in place. Not only that, but the process leaves little room for error or people changing their minds. Instead, those "change requests" come in at the last stage when they do the most damage. And being that a bug-fix's cost increases over time, this is a costly way to write code. I am no waterfall expert. As described, is this waterfall being mishandled in some way? How does waterfall address my concerns?

  • Apparent leak in Mozilla Firefox

    - by LeopardSkinPillBoxHat
    I use Mozilla Firefox 3.6 all day, opening and closing tabs quite regularly. I am noticing over time that the firefox.exe process size keeps growing and growing over time. Initially I put this down to memory fragmentation caused by opening and closing tabs, but now I am suspecting that there is a memory leak in one of the add-ons that I have installed. The problem I am seeing is that when the process size gets to about 1.5GB in the "Mem Usage" stat in Task Manager (and it gets there quite regularly), Firefox freezes up. Does anyone have any ideas about how I could diagnose whether: Any of the add-ons are leaking memory? Something else is causing this problem?

  • Qt's future in the light of Nokia-Microsoft partnership

    - by Shinnok
    In case you missed it, a lot has happened in the last two day that could potentially impact the Qt framework, for the worse. :-( It will impact the mobile sector in several and probably not currently acknowledged ways, for sure. It started yesterday with Nokia's CEO Stephen Elop internal letter depicting Nokia sitting on a burning platform and the need for a big and aggressive shift in business. A day later, at the Nokia World conference, Nokia announced the partnership with Microsoft , which at the moment resumes to Nokia adopting the Windows Phone 7 platform and development environment, dumping Symbian along the road and tagging Meego as R&D(a pretty dangerous keyword if you ask me), as for Maemo/N900 series i guess it's bye bye for good. I know what you're thinking but no, Qt is not going to be ported to the Window Phone platform. And i'm also scared about this. You can watch the Elop & Ballmer joint press release here. Now after reading this huge thread on the Qt-interest mailing list i can't help but wonder, what is the future of Qt at Nokia, now that they aren't focused(at all?) on Qt anymore(remember the full focus switch on Qt as main development framework for all Nokia products(including Symbian, yes) back in October?). I love Qt, in my opinion it is the only true cross-platform application development framework and one of the few to make C++ development a joy(to the extent possible) and good things has happened to the framework and considerable momentum while under Nokia, thus i am wondering, what are the chances that Qt might suffer a slow death at Nokia after this? Yes i know about KDE.org and the fact that Qt is easily spawnable, but i still feel uneasy. It also must be horrible for all of the efforts either by Nokia employees or third parties that have gone into Symbian and all of the Ovi Store Symbian/Qt content and business and why not, Maemo/Meego. There are also massive layouts planned, i suspect Symbian techs and Qt? I'd love to hear your input on this? Is Qt future safe&proof? LE: The question as been gradually revised, improved and better referenced, thus you might want to throw a quick re-read to see what you might have missed.

  • XNA extending the existing Content type

    - by Maarten
    We are doing a game in XNA that reacts to music. We need to do some offline processing of the music data and therefore we need a custom type containing the Song and some additional data: // Project AudioGameLibrary namespace AudioGameLibrary { public class GameTrack { public Song Song; public string Extra; } } We've added a Content Pipeline extension: // Project GameTrackProcessor namespace GameTrackProcessor { [ContentSerializerRuntimeType("AudioGameLibrary.GameTrack, AudioGameLibrary")] public class GameTrackContent { public SongContent SongContent; public string Extra; } [ContentProcessor(DisplayName = "GameTrack Processor")] public class GameTrackProcessor : ContentProcessor<AudioContent, GameTrackContent> { public GameTrackProcessor(){} public override GameTrackContent Process(AudioContent input, ContentProcessorContext context) { return new GameTrackContent() { SongContent = new SongProcessor().Process(input, context), Extra = "Some extra data" // Here we can do our processing on 'input' }; } } } Both the Library and the Pipeline extension are added to the Game Solution and references are also added. When trying to use this extension to load "gametrack.mp3" we run into problems however: // Project AudioGame protected override void LoadContent() { AudioGameLibrary.GameTrack gameTrack = Content.Load<AudioGameLibrary.GameTrack>("gametrack"); MediaPlayer.Play(gameTrack.Song); } The error message: Error loading "gametrack". File contains Microsoft.Xna.Framework.Media.Song but trying to load as AudioGameLibrary.GameTrack. AudioGame contains references to both AudioGameLibrary and GameTrackProcessor. Are we maybe missing other references?

  • What are benefit/drawbacks of classifying defects during a peer code review

    - by DXM
    About 3 months ago, our engineering group rolled out Review Board to be used for all peer code reviews. Today, I had a discussion with one of the people involved in that process and found out that we are already looking for a replacement (possibly something commercial) because of several missing features. One of the features that is apparently asked by many people is the ability to classify/categorize each code review comment (i.e. is it a style issue, coding convention, resource leak, logic error, crash... whatever). For those teams that regularly practice code review, is this categorization a common practice? Do you do it? have you done it in the past? Is it good/bad? On one hand, it gives the team some more metrics and possibly will indicate more specific areas where developers may potentially need to be trained in (at least that seems to be the argument). Are there other benefits? And on the other hand, and this is my concern, is that it will slow down code review process that much more. As a team lead, I've done a fairly large share of reviews, and I've always liked the ability, to highlight a chunk of code, hammer off a comment and move on as fast as possible. Although I haven't tried it personally, I have a feeling that expanding that combo box every time and scrolling/searching for the right category would feel like something is tripping you. Also if we start keeping metrics on this stuff, my other concern is that valuable code review meeting time will be spent on arguing whether something is a logic error or if it should be classified as a crash.

  • Importing PSTs with PowerShell in Exchange 2010 SP1

    Unless you use Red Gate's PST Importer, the import and export of PST files with Exchange 2010 is a complex and error-prone business. Microsoft have acknowledged this in the release of Exchange 2010 SP1, since they have now re-engineered the way that PSTs are handled to try and ease the pain of importing and exporting them, but it is still a matter of using Powershell with cmdlets, rather than a GUI. Jaap Wesselius takes a look at the new process.

  • The role of the Infrastructure DBA

    - by GavinPayneUK
    Do you have someone performing an Infrastructure DBA role within your organisation? Do you realise why today you now might need one? When I first started working with SQL Server there were three distinct roles in the SQL Server virtual team: developer , DBA and sysadmin . In my simple terms, the developer looked after the “code”: the schema, stored procedures, and any ETL to get data in, out or updated within the database. They could talk in business entity terms about Customer numbers, Product codes...(read more)

  • One of my apache processes is huge - how can I find out why?

    - by Malcolm Box
    I'm running Apache 2.2.12 with mod_wsgi, hosting a Django site. Most of the apache child processes weigh in at about 125MB RSS, but occasionally I see one child balloon to 1GB RSS. At this point there's usually 1 huge process (1GB), a couple of large ones (500MB) and the rest are still ~125MB. These are the mod_wsgi daemon processes. I've tried using memory leak tracing in Python to see if it's the Django code, and I see no leaks. Looking in the logs doesn't show any particularly strange requests. I'm stumped on how to figure out what's causing this - any ideas? Also, any workaround ways to kill the large apache process when it gets too big, without bringing apache down? Some more details: Not using mod_php Using pre-fork

  • How to debug why w3wp.exe crashes randomly?

    - by sassyboy
    On the main production server, the IIS worker process crashes sometimes. From the event viewer I get the following information. Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8 Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319 Exception code: 0xe053534f Fault offset: 0x0000b9bc Faulting process id: 0x%9 Faulting application start time: 0x%10 Faulting application path: %11 Faulting module path: %12 Report Id: %13 This happens randomly on the prod server and I have not been able to recreate this crash anywhere else. This was happening on IIS 6, and we recently moved to Windows Server 2008 and IIS 7.5 and the crash happens there as well. How to go about finding the root cause of this?

  • How to install compat-drivers or compat-wireless

    - by Sasho
    Could someone please explain me in detail how to install some of this drivers. I am running Ubuntu 12.04.2 and have the infamous (as I see everywhere in the net) problem with Atheros AR9462 wifi card. I tried everything to fix it and compat drivers are the only solution that I haven't tried. I tried to install some random package from kernel.org site and it couldn't make the driver (it threw some error). Then I updated the kernel to 3.10-rc7 and downloaded the last release of compat drivers and again the same problem occured. I reinstalled Ubuntu 12.04.2 and now I am using the 3.5 kernel because I don't know if rc7 is stable version. So my question is which compat wireless or compat drivers to download for this kernel and what is the process of installing. I tried with some command from the repository and it returned that it's not found. PS I am new to Ubuntu and Linux in general so explaining at length the install process and which driver I should install would be appreciated.

  • IMAP can't access virtual account sharing name with local user account

    - by chernevik
    I am setting up a postfix/dovecot mail server with virtual accounts, per the Chris Haas tutorial. I'm finding that virtual users who also have local user accounts on the mail server cannot access their email remotely via IMAP. They're told they cannot login. (I'm using Thunderbird for that). These same users can login when emulating IMAP locally via telnet. Virtual users without local accounts have no trouble with IMAP access from remote clients. These local user accounts have vestiges of prior efforts in their home directories: mbox files, Mail and mail directories. I've looked at the logs for clues to where the remote login process is failing (dovecot authentication failure? confusion over where emails are stored?) but found nothing helpful. I haven't found much in the dovecot or postfix documentation that describes the IMAP login process and expectations in enough detail to help me diagnose this. So: how do I go about identifying the problem and researching a solution?

  • Real-time Big Data Analytics is a reality for StubHub with Oracle Advanced Analytics

    - by Mark Hornick
    What can you use for a comprehensive platform for real-time analytics? How can you process big data volumes for near-real-time recommendations and dramatically reduce fraud? Learn in this video what Stubhub achieved with Oracle R Enterprise from the Oracle Advanced Analytics option to Oracle Database, and read more on their story here. Advanced analytics solutions that impact the bottom line of a business are challenging due to the range of skills and individuals involved in realizing such solutions. While we hear a lot about the role of the data scientist, that role is but one piece of the puzzle. Advanced analytics solutions also have an operationalization aspect that also requires close proximity to where the transactional activity occurs. The data scientist needs access to the right data with which to model the business problem. This involves IT for data collection, management, and administration, as well as ensuring zero downtime (a website needs to be up 24x7). This also involves working with the data scientist to keep predictive models refreshed with the latest scripts. Integrating advanced analytics solutions into enterprise apps involves not just generating predictions, but supporting the whole life-cycle from data collection, to model building, model assessment, and then outcome assessment and feedback to the model building process again. Application and web interface designers need to take into account how end users will see and use the advanced analytics results, e.g., supporting operations staff that need to handle the potentially fraudulent transactions. As just described, advanced analytics projects can be "complicated" from just a human perspective. The extent to which software can simplify the interactions among users and systems will increase the likelihood of project success. The ability to quickly operationalize advanced analytics projects and demonstrate measurable value, means the difference between a successful project and just a nice research report. By standardizing on Oracle Database and SQL invocation of R, along with in-database modeling as found in Oracle Advanced Analytics, expedient model deployment and zero downtime for refreshing models becomes a reality. Meanwhile, data scientists are also able to explore leading edge techniques available in open source. The Oracle solution propels the entire organization forward to realize the value of advanced analytics.

  • Fast Data: Go Big. Go Fast.

    - by J Swaroop
    Cross-posting Dain Hansen's excellent recap of the Big Data/Fast Data announcement during OOW: For those of you who may have missed it, today’s second full day of Oracle OpenWorld 2012 started with a rumpus. Joe Tucci, from EMC outlined the human face of big data with real examples of how big data is transforming our world. And no not the usual tried-and-true weblog examples, but real stories about taxi cab drivers in Singapore using big data to better optimize their routes as well as folks just trying to get a better hair cut. Next we heard from Thomas Kurian who talked at length about the important platform characteristics of Oracle’s Cloud and more specifically Oracle’s expanded Cloud Services portfolio. Especially interesting to our integration customers are the messaging support for Oracle’s Cloud applications. What this means is that now Oracle’s Cloud applications have a lightweight integration fabric that on-premise applications can communicate to it via REST-APIs using Oracle SOA Suite. It’s an important element to our strategy at Oracle that supports this idea that whether your requirements are for private or public, Oracle has a solution in the Cloud for all of your applications and we give you more deployment choice than any vendor. If this wasn’t enough to get the juices flowing, later that morning we heard from Hasan Rizvi who outlined in his Fusion Middleware session the four most important enterprise imperatives: Social, Mobile, Cloud, and a brand new one: Fast Data. Today, Rizvi made an important step in the definition of this term to explain that he believes it’s a convergence of four essential technology elements: Event Processing for event filtering, business rules – with Oracle Event Processing Data Transformation and Loading - with Oracle Data Integrator Real-time replication and integration – with Oracle GoldenGate Analytics and data discovery – with Oracle Business Intelligence Each of these four elements can be considered (and architect-ed) together on a single integrated platform that can help customers integrate any type of data (structured, semi-structured) leveraging new styles of big data technologies (MapReduce, HDFS, Hive, NoSQL) to process more volume and variety of data at a faster velocity with greater results.  Fast data processing (and especially real-time) has always been our credo at Oracle with each one of these products in Fusion Middleware. For example, Oracle GoldenGate continues to be made even faster with the recent 11g R2 Release of Oracle GoldenGate which gives us some even greater optimization to Oracle Database with Integrated Capture, as well as some new heterogeneity capabilities. With Oracle Data Integrator with Big Data Connectors, we’re seeing much improved performance by running MapReduce transformations natively on Hadoop systems. And with Oracle Event Processing we’re seeing some remarkable performance with customers like NTT Docomo. Check out their upcoming session at Oracle OpenWorld on Wednesday to hear more how this customer is using Event processing and Big Data together. If you missed any of these sessions and keynotes, not to worry. There's on-demand versions available on the Oracle OpenWorld website. You can also checkout our upcoming webcast where we will outline some of these new breakthroughs in Data Integration technologies for Big Data, Cloud, and Real-time in more details.
