• Access Windows Home Server from an Ubuntu Computer on your Network

  - by Mysticgeek

  If you’re a Windows Home Server user, there may be times when you need to access it from an Ubuntu machine on your network. Today we take a look at the process of accessing files on your home server from Ubuntu. Note: In this example we’re using Windows Home Server with PowerPack 3, and Ubuntu 10.04 running on a home network. Access WHS from Ubuntu To access files on your home server from Ubuntu, click on Places then select Network. You should now see your home server listed in the Network folder as well as other Windows machines…double-click the server to access it. If you don’t see your server listed, you might need to go into Windows Network \ Workgroup and find it there. You’ll be prompted to enter in the correct credentials for WHS just as you would when accessing it from a Windows machine. It’s your choice if you want to have the password remembered or not…make your selection and click Connect. Now you will see the available folders on your home server. In this example we signed in with Administrator credentials, so we have access to everything. Double-click on the folder share you want to access content from…here we see MS Office documents on the server. Or, here we take a look at a music folder with various MP3 files which you can make Ubuntu play. You can access the files directly from the server, provided there is a Linux app that can handle the file type. In this example we opened a Word document in OpenOffice. Here we’re playing an MKV movie file from the server in Totem Movie Player.   You can easily search for files on the server as well… If you want to store your Ubuntu files on WHS it’s just a matter of dragging them to the correct WHS folder you want them in. If you’re using an Ubuntu computer on your home network and need to access files from Windows Home Server, luckily it’s a straight-forward process. You’ll often have to find the correct software to use Windows files, but even that’s getting much easier with version 10.04.

• SQL SERVER – ColumnStore Index – Batch Mode vs Row Mode

  - by pinaldave

  What do you do when you are in a hurry and hear someone say things which you do not agree or is wrong? Well, let me tell you what I do or what I recently did. I was walking by and heard someone mentioning “Columnstore Index are really great as they are using Batch Mode which makes them seriously fast.” While I was passing by and I heard this statement my first reaction was I thought Columnstore Index can use both – Batch Mode and Row Mode. I stopped by even though I was in a hurry and asked the person if he meant that Columnstore indexes are seriously fast because they use Batch Mode all the time or Batch Mode is one of the reasons for Columnstore Index to be faster. He responded that Columnstore Indexes can run only in Batch Mode. However, I do not like to confront anybody without hearing their complete story. Honestly, I like to do information sharing and avoid confronting as much as possible. There are always ways to communicate the same positively. Well, this is what I did, I quickly pull up my earlier article on Columnstore Index and copied the script to SQL Server Management Studio. I created two versions of the script. 1) Very Large Table 2) Reasonably Small Table. I a query which uses columnstore index on both of the versions. I found very interesting result of the my tests. I saved my tests and sent it to the person who mentioned about that Columnstore Indexes are using Batch Mode only. He immediately acknowledged that indeed he was incorrect in saying that Columnstore Index uses only Batch Mode. What really caught my attention is that he also thanked me for sending him detail email instead of just having argument where he and I both were standing in the corridor and neither have no way to prove any theory. Here is the screenshots of the both the scenarios. 1) Columnstore Index using Batch Mode 2) Columnstore Index using Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput.  Batch mode processing spreads metadata access costs and overhead over all the rows in a batch.  Batch mode processing operates on compressed data when possible leading superior performance. Here is one last point – Columnstore Index can use Batch Mode or Row Mode but Batch Mode processing is only available in Columnstore Index. I hope this statement truly sums up the whole concept.

• SQL Server Scripts I Use

  - by Bill Graziano

  When I get to a new client I usually find myself using the same set of scripts for maintenance and troubleshooting.  These are all drop in solutions for various maintenance issues. Reindexing.  I use Michelle Ufford’s (SQLFool) re-indexing script.  I like that it has a throttle and only re-indexes when needed.  She also has a variety of other interesting scripts on her blog too. Server Activity.  Adam Machanic is up to version 10 of sp_WhoIsActive.  It’s a great replacement for the sp_who* stored procedures and does so much more.  If a server is acting funny this is one of the first tools I use. Backups.  Tara Kizer has a great little T-SQL script for SQL Server backups.  Wait Stats.  Paul Randal has a great script to display wait stats.  The biggest benefit for me is that his script filters out at least three dozen wait stats that I just don’t care about (for example LAZYWRITER_SLEEP). Update Statistics.  I didn’t find anything I liked so I wrote a simple script to update stats myself.  The big need for me was that it had to run inside a time window and update the oldest statistics first.  Is there a better one? Diagnostic Queries.  Glenn Berry has a huge collection of DMV queries available.  He also just highlighted five of them including two I really like dealing with unused indexes and suggested indexes. Single Use Query Plans.  Kim Tripp has a script that counts the number of single-use query plans.  This should guide you in whether to enable the Optimize for Adhoc Workloads option in SQL Server 2008. Granting Permissions to Developers.  This is one of those scripts I didn’t even know I needed until I needed it.  Kendra Little wrote it to grant a login read-only permission to all the databases.  It also grants view server state and a few other handy permissions.   What else do you use?  What should I add to my list?

• SQL SERVER – Log File Growing for Model Database – model Database Log File Grew Too Big

  - by pinaldave

  After reading my earlier article SQL SERVER – master Database Log File Grew Too Big, I received an email recently from another reader asking why does the log file of model database grow every day when he is not carrying out any operation in the model database. As per the email, he is absolutely sure that he is doing nothing on his model database; he had used policy management to catch any T-SQL operation in the model database and there were none. This was indeed surprising to me. I sent a request to access to his server, which he happily agreed for and within a min, we figured out the issue. He was taking the backup of the model database every day taking the database backup every night. When I explained the same to him, he did not believe it; so I quickly wrote down the following script. The results before and after the usage of the script were very clear. What is a model database? The model database is used as the template for all databases created on an instance of SQL Server. Any object you create in the model database will be automatically created in subsequent user database created on the server. NOTE: Do not run this in production environment. During the demo, the model database was in full recovery mode and only full backup operation was performed (no log backup). Before Backup Script Backup Script in loop DECLARE @FLAG INT SET @FLAG = 1 WHILE(@FLAG < 1000) BEGIN BACKUP DATABASE [model] TO  DISK = N'D:\model.bak' SET @FLAG = @FLAG + 1 END GO After Backup Script Why did this happen? The model database was in full recovery mode and taking full backup is logged operation. As there was no log backup and only full backup was performed on the model database, the size of the log file kept growing. Resolution: Change the backup mode of model database from “Full Recovery” to “Simple Recovery.”. Take full backup of the model database “only” when you change something in the model database. Let me know if you have encountered a situation like this? If so, how did you resolve it? It will be interesting to know about your experience.

• dotnet Cologne 2011 : Anmeldung ab 14. März

  - by WeigeltRo

  Am 6.5.2011 findet in Köln die dotnet Cologne 2011 statt, eine von der .NET User Group Köln und der von mir geleiteten Gruppe Bonn-to-Code.Net gemeinsam organisierte Community-Konferenz rund um .NET. Die “dotnet Cologne” hat sich mittlerweile als die große .NET Community- Konferenz in Deutschland etabliert. So war die letztjährige dotnet Cologne 2010 mit 300 Teilnehmern bereits einen Monat im Voraus ausgebucht. Und heise online schrieb: “Inzwischen besitzt die dotnet Cologne ein weites Einzugsgebiet. Die Teilnehmer kommen nicht mehr ausschließlich aus dem Kölner Umfeld, sondern aus allen Teilen Deutschlands [...] Die gute Qualität des Vorjahres in Verbindung mit einem geringen Preis hat sich schnell herumgesprochen, sodass Teilnehmer aus Bayern oder Thüringen keine Ausnahme waren.” Auch in diesem Jahr erwartet die Teilnehmer ein ganzer Tag voll mit Themen rund um .NET. Auf der Website http://www.dotnet-cologne.de sind dazu jetzt die ersten Vorträge, Sprecher sowie Infos zur Anmeldung veröffentlicht. Die Anmeldung ist ab Montag, den 14.3.2011 um 14:00 freigeschaltet. Es empfiehlt sich, schnell zu handeln, denn für die 100 ersten Teilnehmer gilt der “Super-Early Bird” Preis von nur 25,- Euro; diese Plätze waren letztes Jahr in Nullkommanix weg. Die Teilnehmer 101 – 200 zahlen den “Early Bird” Preis von 40,- Euro, ab Platz 201 gilt der “Normalpreis” von 55,- Euro. Aber egal ob “Super-Early”, “Early” oder “Normal”: 25 Vorträge auf 5 Tracks, gehalten von bekannten Namen der .NET Community, dazu den ganzen Tag über Verpflegung und Getränke – das ist zu diesem Preis ein sehr attraktives Angebot. Wir haben damit eine Konferenz organisiert, die wir selbst gerne besuchen würden. Ganz im Sinne “von Entwicklern, für Entwickler”. Was ist neu? Das Feedback vom letzten Jahr war sehr positiv, den Leuten hat’s einfach gut gefallen. Gleichwohl haben wir Feedback-Bögen, Blog-Einträge und Tweets sehr aufmerksam ausgewertet und bei der Organisation berücksichtigt: Der neue Veranstaltungsort, das Komed im Mediapark Köln, ist zentral gelegen und verfügt über günstige Parkmöglichkeiten Die Räumlichkeiten bieten mehr Platz für Teilnehmer, Sponsoren und natürlich auch das Mittagessen Wir haben dieses Jahr einige etwas speziellere Vorträge auf Level 300 und 400 im Programm, um neben fundierten Einführungen in Themengebiete auch “Deep Dives” für Experten anbieten zu können. Längere Pausen zwischen den Vorträgen ermöglichen es den Teilnehmern besser, nach den Vorträgen mit den Sprechern verbleibende Fragen zu klären, sich an den Sponsorenständen Infos zu holen oder einfach Kontakte mit Gleichgesinnten zu knüpfen. Was das Fördern der Kommunikation unter den Teilnehmern angeht, haben wir schon die eine oder andere Idee im Kopf. Aber einiges davon hängt nicht zuletzt von finanziellen Faktoren ab – und damit sind wir schon beim Thema: Es gibt noch Sponsoring-Möglichkeiten! Die dotnet Cologne 2011 ist die Gelegenheit, Produkte vorzustellen, neue Mitarbeiter zu suchen oder generell den Namen einer Firma bei den richtigen Leuten zu platzieren. Nicht ohne Grund unterstützen uns viele Sponsoren dieses Jahr zum wiederholten Mal. Vom Software-Sponsor für die Verlosung bis hin zum Aussteller vor Ort – es gibt vielfältige Möglichkeiten und wir schicken auf Anfrage gerne unsere Sponsoreninfos zu.

• Silverlight Death Trolls Dancing on XAML&rsquo;s Grave

  - by D'Arcy Lussier

  I’m starting to see a whole bunch of tweets and blog posts on how Silverlight/WPF is dead, or how the XAML team has been disbanded at Microsoft, or how someone predicted Silverlight would die, blah blah blah. They all have a similar ring to it though: “Told ya so!” “They were stupid ideas anyway!” “Serves Microsoft right, boy are they dumb!” Let me tell you something, all those that are gleefully raving about Silverlight/WPF’s demise are nothing more than death trolls. Let’s assume that everything out there is true. Microsoft is obviously moving towards HTML 5 in a huge way (TechCrunch pointed out that SkyDrive has replaced its Silverlight based version with an HTML 5 one), and not just on the web as we’ve seen with recent announcements about how HTML 5 apps will be natively supported on Windows 8. WPF never caught on in the marketplace, regardless of its superior technology offering to Winforms. And Silverlight…well, it gave Flash a good run for its money, but plug-in based web applications are becoming passé in light of HTML 5. (It’s interesting that at a developer conference I put on just a few weeks ago, only 1 out of 60+ sessions included Silverlight. 5 focussed on HTML 5.) So what does this *death* of Silverlight/WPF/XAML mean then in the grand scheme of things (again, assuming that they truly *are* dying/dead)? Well, nothing really…at least nothing bad. Silverlight has given us some fantastic applications and experiences (Vancouver Olympics anyone?), and WP7 couldn’t have launched without Silverlight as its development platform. And WPF, although it had putrid adoption, has had some great success stories. A Canadian company that I talked to recently showed me how they re-wrote their point-of-sale application entirely in WPF, and the product is a huge success providing features their competitors aren’t. Arguably (and I say that only because I know I’m going to get WTF comments for this), VS.NET 2010 is a great example of what a WPF app can provide over previous C++ based applications. Technologies evolve. In a decade we’ve had 5 versions of the .NET framework, seen languages like J# come and go, seen F# appear, see communications layers change with WCF, seen EF go through multiple evolutions and traditional ADO.NET Datasets go extinct (from actual use anyway), and ASP.NET Webforms be replaced with ASP.NET MVC as a preferred web platform. Is Silverlight and WPF done? Maybe…probably?…thing is, it doesn’t really affect me personally in any way, or you…so why would we care if its gets replaced with something better and more robust that we can build better solutions with? Just remember the golden rule: don’t feed the trolls.

• Oracle's Australian Graduate Recruitment Program

  - by david.talamelli

  I have been with Oracle for 5 years now and one thing that I have found that there is never a shortage of here is - Variety. Over the last 5 years I have had the opportunity to work on projects across various countries, across various technologies and skill-sets and also across various level of seniority. No two days are the same. One of the projects I was fortunate to be involved in occurred last year and it is one of the ones that is closest to me. Last year I was able to take responsibility for our 2011 Graduate Recruitment drive in Australia. Two weeks ago I went to Sydney to meet our Graduates who started in February 2011 with us and it was great to see them come to the end (or beginning actually) of our journey together. I am excited at the potential of what our Graduates careers will develop into here with us. I remember at our interviewing last year trying to explain life in Oracle, it is great to see those same Graduates with us now learning and developing life and business skills that I hope they will take with them in their professional careers. I was talking to one of my colleagues this week who mentioned the excitement and energy that our new Graduates bring is infectious, and I agree it really is. Our Graduates have a big learning curve ahead of them and they are about to start going on rotations into some of our Business Groups - but I think it is a great experience to see how a global company operates and pulls together to achieve results together. Here is a picture we took the other week of this year's Oracle Graduates (if any of our Graduates are reading this blog - it was great seeing you in NSW and I do wish you all the success here at Oracle) Once again Oracle's Graduate Program will be running in 2011 in Australia (Graduates will start in Jan/Feb 2012). The Oracle Australia Graduate Development Program is a one-year program consisting of orientation, formal training, project rotations in one core line of business and finally job placement. The formal training is a combination of structured development programs on soft skills and functional competencies via various delivery formats. Graduates are also expected to work in a team environment and complete multiple projects addressing real business challenges and at the time gaining a broad business understanding. For our Australia program we are hiring in our North Ryde and Melbourne offices. Resume submissions are being accepted now. First Round interviews will take place in June 2011 with Final Round interviews in July 2011. The Australia Graduate Program is open to Australian Residents and Citizens who are either in the final year of their studies or have graduated the previous year. For more details on Oracle and our Graduate Program visit our Campus website To express your interest, mail your resume to [email protected]

• Is 4-5 years the “Midlife Crisis” for a programming career?

  - by Jeff

  I’ve been programming C# professionally for a bit over 4 years now. For the past 4 years I’ve worked for a few small/medium companies ranging from “web/ads agencies”, small industry specific software shops to a small startup. I've been mainly doing "business apps" that involves using high-level programming languages (garbage collected) and my overall experience was that all of the works I’ve done could have been more professional. A lot of the things were done incorrectly (in a rush) mainly due to cost factor that people always wanted something “now” and with the smallest amount of spendable money. I kept on thinking maybe if I could work for a bigger companies or a company that’s better suited for programmers, or somewhere that's got the money and time to really build something longer term and more maintainable I may have enjoyed more in my career. I’ve never had a “mentor” that guided me through my 4 years career. I am pretty much blog / google / self taught programmer other than my bachelor IT degree. I’ve also observed another issue that most so called “senior” programmer in “my working environment” are really not that senior skill wise. They are “senior” only because they’ve been a long time programmer, but the code they write or the decisions they make are absolutely rubbish! They don't want to learn, they don't want to be better they just want to get paid and do what they've told to do which make sense and most of us are like that. Maybe that’s why they are where they are now. But I don’t want to become like them I want to be better. I’ve run into a mental state that I no longer intend to be a programmer for my future career. I started to think maybe there are better things out there to work on. The more blogs I read, the more “best practices” I’ve tried the more I feel I am drifting away from “my reality”. But I am not a great programmer otherwise I don't think I am where I am now. I think 4-5 years is a stage that can be a step forward career wise or a step out of where you are. I just wanted to hear what other have to say about what I’ve mentioned above and whether you’ve experienced similar situation in your past programming career and how you dealt with it. Thanks.

• Asp.net session on browser close

  - by budugu

  Note: Cross posted from Vijay Kodali's Blog. Permalink How to capture logoff time when user closes browser? Or How to end user session when browser closed? These are some of the frequently asked questions in asp.net forums. In this post I'll show you how to do this when you're building an ASP.NET web application. Before we start, one fact: There is no full-proof technique to catch the browser close event for 100% of time. The trouble lies in the stateless nature of HTTP. The Web server is out of the picture as soon as it finishes sending the page content to the client. After that, all you can rely on is a client side script. Unfortunately, there is no reliable client side event for browser close. Solution: The first thing you need to do is create the web service. I've added web service and named it AsynchronousSave.asmx.    Make this web service accessible from Script, by setting class qualified with the ScriptServiceAttribute attribute...  Add a method (SaveLogOffTime) marked with [WebMethod] attribute. This method simply accepts UserId as a string variable and writes that value and logoff time to text file. But you can pass as many variables as required. You can then use this information for many purposes. To end user session, you can just call Session.Abandon() in the above web method. To enable web service to be called from page’s client side code, add script manager to page. Here i am adding to SessionTest.aspx page When the user closes the browser, onbeforeunload event fires on the client side. Our final step is adding a java script function to that event, which makes web service calls. The code is simple but effective My Code HTML:( SessionTest.aspx ) C#:( SessionTest.aspx.cs ) That’s’ it. Run the application and after browser close, open the text file to see the log off time. The above code works well in IE 7/8. If you have any questions, leave a comment.

  Note: Cross posted from Vijay Kodali's Blog. Permalink How to capture logoff time when user closes browser? Or How to end user session when browser closed? These are some of the frequently asked questions in asp.net forums. In this post I'll show you how to do this when you're building an ASP.NET web application. Before we start, one fact: There is no full-proof technique to catch the browser close event for 100% of time. The trouble lies in the stateless nature of HTTP. The Web server is out of the picture as soon as it finishes sending the page content to the client. After that, all you can rely on is a client side script. Unfortunately, there is no reliable client side event for browser close. Solution: The first thing you need to do is create the web service. I've added web service and named it AsynchronousSave.asmx.    Make this web service accessible from Script, by setting class qualified with the ScriptServiceAttribute attribute...  Add a method (SaveLogOffTime) marked with [WebMethod] attribute. This method simply accepts UserId as a string variable and writes that value and logoff time to text file. But you can pass as many variables as required. You can then use this information for many purposes. To end user session, you can just call Session.Abandon() in the above web method. To enable web service to be called from page’s client side code, add script manager to page. Here i am adding to SessionTest.aspx page When the user closes the browser, onbeforeunload event fires on the client side. Our final step is adding a java script function to that event, which makes web service calls. The code is simple but effective My Code HTML:( SessionTest.aspx ) C#:( SessionTest.aspx.cs ) That’s’ it. Run the application and after browser close, open the text file to see the log off time. The above code works well in IE 7/8. If you have any questions, leave a comment.

• List of all states from COMPOSITE_INSTANCE, CUBE_INSTANCE, DLV_MESSAGE tables

  - by Deepak Arora

  In many of my engagements I get asked repeatedly about the states of the composites in 11g and how to decipher them, especially when we are troubleshooting issues around purging. I have compiled a list of all the states from the COMPOSITE_INSTANCE, CUBE_INSTANCE, and DLV_MESSAGE tables. These are the primary tables that are used when using BPEL composites and how they are used with the ECID.  Composite State Values COMPOSITE_INSTANCE States State Description 0 Running 1 Completed 2 Running with faults 3 Completed with faults 4 Running with recovery required 5 Completed with recovery required 6 Running with faults and recovery required 7 Completed with faults and recovery required 8 Running with suspended 9 Completed with suspended 10 Running with faults and suspended 11 Completed with faults and suspended 12 Running with recovery required and suspended 13 Completed with recovery required and suspended 14 Running with faults, recovery required, and suspended 15 Completed with faults, recovery required, and suspended 16 Running with terminated 17 Completed with terminated 18 Running with faults and terminated 19 Completed with faults and terminated 20 Running with recovery required and terminated 21 Completed with recovery required and terminated 22 Running with faults, recovery required, and terminated 23 Completed with faults, recovery required, and terminated 24 Running with suspended and terminated 25 Completed with suspended and terminated 26 Running with faulted, suspended, and terminated 27 Completed with faulted, suspended, and terminated 28 Running with recovery required, suspended, and terminated 29 Completed with recovery required, suspended, and terminated 30 Running with faulted, recovery required, suspended, and terminated 31 Completed with faulted, recovery required, suspended, and terminated 32 Unknown 64 - CUBE_INSTANCE States State Description 0 STATE_INITIATED 1 STATE_OPEN_RUNNING 2 STATE_OPEN_SUSPENDED 3 STATE_OPEN_FAULTED 4 STATE_CLOSED_PENDING_CANCEL 5 STATE_CLOSED_COMPLETED 6 STATE_CLOSED_FAULTED 7 STATE_CLOSED_CANCELLED 8 STATE_CLOSED_ABORTED 9 STATE_CLOSED_STALE 10 STATE_CLOSED_ROLLED_BACK DLV_MESSAGE States State Description 0 STATE_UNRESOLVED 1 STATE_RESOLVED 2 STATE_HANDLED 3 STATE_CANCELLED 4 STATE_MAX_RECOVERED Since now in 11g the Invoke_Messages table is not there so to distinguish between a new message (Invoke) and callback (DLV) and there is DLV_TYPE column that defines the type of message: DLV_TYPE States State Description 1 Invoke Message 2 DLV Message MEDIATOR_INSTANCE STATE Description  0  No faults but there still might be running instances  1  At least one case is aborted by user  2  At least one case is faulted (non-recoverable)  3  At least one case is faulted and one case is aborted  4  At least one case is in recovery required state  5 At least one case is in recovery required state and at least one is aborted  6 At least one case is in recovery required state and at least one is faulted  7 At least one case is in recovery required state, one faulted and one aborted  >=8 and < 16  Running >= 16   Stale In my next blog posting I will walk through the lifecycle of a BPEL process using the above states for the following use cases: - New BPEL process - initial Receive activity - Callback BPEL process - mid-level Receive activity As always comments and questions welcome!

• SQLAuthority News – Social Media Series – YouTube and Movies

  - by pinaldave

  Pinal Dave on Youtube! Some people might not know it, but YouTube is actually more than a place to watch funny cat videos and people singing their favorite pop songs – it’s actually a social media site.  When you are a member of YouTube you can follow people who regularly post videos, post video responses of your own, and even gain a following for your own videos.  I myself was not aware of YouTube’s potential until recently, when I started to make SQL Server in Sixty Seconds videos. YouTube is very different than other types of social media, and a big factor is that anyone can look at videos without being a member.  Unlike other social media sites, like Twitter and Facebook, you have to have an account in order to participate.  But on YouTube you are even more anonymous.  To make and post videos you need an account, but anyone who comes to the site can look at what you’ve made without signing in or leaving any trace of having seen your material.  This makes YouTube very anonymous and hard to track. However, we should not overlook the power of video on the internet.  Over the past few months I have been making SQL Server in Sixty Second videos and have come to love it.  It is very exciting to be able to talk about a subject that mostly I write about, and for many people video is far more accessible and easy to understand.   I have really enjoyed diving into something new, and would love to have more people check out these videos and give me feedback.  You can find me at www.youtube.com/user/pinaldave. I am very excited with all the possibilities on YouTube and it might just be the technology evangelist in me, but I would love for other people to discover how fun and exciting this site can be, too.  Don’t think of it as just a place to find funny videos and waste a few minutes of your time, think of it as a place to learn and interact with interesting people.  Come watch a few of my videos, while you’re there.  Remember, everything is free and there are no contracts to sign, but I hope that you get as excited as I am and join up.  We need more people creating good content on this site!

• Speech Recognition

  - by DesigningCode

  Today I was asked to write a wee application for someone so that they could turn pages on their ebooks without having to reach for their keyboard or mouse… that way they could do craft or knit or whatever they are doing while they are reading. I vaguely remember that windows has something built in, but have never really played with it before.   I have in the past turned on the screen reader and impressed my kids by making the computer saying “amusing” phrases along the lines of “Zac has a smelly bum”. So instead of firing up Visual Studio and getting stuck into the juciy task of writing a speech recognition program…. I typed “speech recognition” into the start menu of my windows 7 computer.   And wow!  I’ve been playing with it for the last 40 minutes or so and have been most impressed.   Dictation wise it certainly misses stuff or gets the wrong words, but I did the training and it certainly improved. But what I’m enjoying is controlling windows. for instance, to start this blog entry  I said “Open Writer”  and it worked no problem.    In fact after I muddled my way through getting going with speech recognition I enjoyed saying “Open notepad” … “close”  over and over again. It allows you to click anywhere on the screen, just say “mousegrid”   and a 1-9 numbered grid comes up,  say a number and it puts a smaller 1-9 numbered grid, and you hone in, till the middle square is on a place you want to click, then you say “click” or “double click”.  if you want to enter a key, say “Press Tab”  for example.   inside programs it understands menu entries.  In fact, while writing this I just said “File”  “Save” and it happily saved. I think I will play around with this for a while more and try it out in visual studio.   Might be quite good for being able to do menu entries instead of grabbing for my mouse…. can keep my hands on the keyboard. ok, wasn’t the first post I wanted to do on geeks with blogs! but hey…   will do some techy posts soon.

• Mac OS X roaming profile from Samba with OpenLDAP backend on Ubuntu 11.10

  - by Sam Hammamy

  I have been battling for a week now to get my Mac (Mountain Lion) to authenticate on my home network's OpenLDAP and Samba. From several sources, like the Ubuntu community docs, and other blogs, and after a hell of a lot of trial and error and piecing things together, I have created a samba.ldif that will pass the smbldap-populate when combined with apple.ldif and I have a fully functional OpenLDAP server and a Samba PDC that uses LDAP to authenticate the OS X Machine. The problem is that when I login, the home directory is not created or pulled from the server. I get the following in system.log Sep 21 06:09:15 Sams-MacBook-Pro.local SecurityAgent[265]: User info context values set for sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got user: sam Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got ruser: (null) Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in pam_sm_authenticate(): Got service: authorization Sep 21 06:09:15 Sams-MacBook-Pro.local authorizationhost[270]: in od_principal_for_user(): no authauth availale for user.

By the way, I intend to create a blog on my vps just for this, and create an install script in python that people can download so no one has to go through what I've had to go through this week :) After some sleep I am going to try to login from a windows machine and report back here.

• SQL SERVER – DMV – sys.dm_os_waiting_tasks and sys.dm_exec_requests – Wait Type – Day 4 of 28

  - by pinaldave

  Previously, we covered the DMV sys.dm_os_wait_stats, and also saw how it can be useful to identify the major resource bottleneck. However, at the same time, we discussed that this is only useful when we are looking at an instance-level picture. Quite often we want to know about the processes going in our server at the given instant. Here is the query for the same. This DMV is written taking the following into consideration: we want to analyze the queries that are currently running or which have recently ran and their plan is still in the cache. SELECT dm_ws.wait_duration_ms, dm_ws.wait_type, dm_es.status, dm_t.TEXT, dm_qp.query_plan, dm_ws.session_ID, dm_es.cpu_time, dm_es.memory_usage, dm_es.logical_reads, dm_es.total_elapsed_time, dm_es.program_name, DB_NAME(dm_r.database_id) DatabaseName, -- Optional columns dm_ws.blocking_session_id, dm_r.wait_resource, dm_es.login_name, dm_r.command, dm_r.last_wait_type FROM sys.dm_os_waiting_tasks dm_ws INNER JOIN sys.dm_exec_requests dm_r ON dm_ws.session_id = dm_r.session_id INNER JOIN sys.dm_exec_sessions dm_es ON dm_es.session_id = dm_r.session_id CROSS APPLY sys.dm_exec_sql_text (dm_r.sql_handle) dm_t CROSS APPLY sys.dm_exec_query_plan (dm_r.plan_handle) dm_qp WHERE dm_es.is_user_process = 1 GO You can change CROSS APPLY to OUTER APPLY if you want to see all the details which are omitted because of the plan cache. Let us analyze the result of the above query and see how it can be helpful to identify the query and the kind of wait type it creates. Click to Enlarage The above query will return various columns. There are various columns that provide very important details. e.g. wait_duration_ms – it indicates current wait for the query that executes at that point of time. wait_type – it indicates the current wait type for the query text – indicates the query text query_plan – when clicked on the same, it will display the query plans There are many other important information like CPU_time, memory_usage, and logical_reads, which can be read from the query as well. In future posts on this series, we will see how once identified wait type we can attempt to reduce the same. Read all the post in the Wait Types and Queue series.

• Tron: Legacy, 3D goggles, and embedded UA

  - by Roger Hart

  The 3D edition of Tron: Legacy opens with embedded user assistance. The film starts with an iconic white-on-black command-prompt message exhorting viewers to keep their 3D glasses on throughout. I can't quote it verbatim, and at the time of writing nor could anybody findable with 5 minutes of googling. But it was something like: "Although parts of the movie are 2D, it was shot in 3D, and glasses should be worn at all times. This is how it was intended to be viewed" Yeah - "intended". That part is verbatim. Wow. Now, I appreciate that even out of the small sub-set of readers who care a rat's ass for critical theory, few will be quite so gung-ho for the whole "death of the author" shtick as I tend to be. And yes, this is ergonomic rather than interpretive, but really - telling an audience how you expect them to watch a movie? That's up there with Big Steve's "you're holding it wrong" Even if it solves the problem, it's pretty arrogant. If anything, it's worse than RTFM. And if enough people are doing it wrong that you have to include the announcement, then maybe - just maybe - you've got a UX and/or design problem. Plus, current 3D glasses are like sitting in a darkened room, cosplaying the lovechild of Spider Jerusalem and Jarvis Cocker. Ok, so that observation was weirder than it was helpful; but seriously, nobody wants to wear the glasses if they don't have to. They ruin the visual experience of the non-3D sections, and personally, I find them pretty disruptive to the suspension of disbelief. This is an old, old, problem, and I'm carping on about it because Tron is enjoyable mass-market slush. It's easier for me to say "no, I can't just put some text on it. It's fundamentally broken, redesign it." in the middle of a small-ish, agile, software project than it would be for some beleaguered production assistant at the end of editing a $200 million movie. But lots of folks in software don't even get to do that. Way more people are going to see Tron, and be annoyed by this, than will ever read a technical communication blog. So hopefully, after two hours of being mildly annoyed, wanting to turn the brightness up, and slowly getting a headache, they'll realise something very, very important: you just can't document your way out of a shoddy UI.

• Monitora&ccedil;&atilde;o com Oracle Enteprrise Manager

  - by fernando.galdino

  A figura abaixo oferece uma visão geral das possibilidades de monitoramento providas pelo Oracle Enterprise Manager (OEM), que é uma ferramenta que permite gerenciar a infraestrutura de TI da empresa. Um componente importante da solução é chanado OEM Grid Control. Esse componente permite gerenciar, visualizar e monitorar diversos elementos a partir de uma mesma console. E que elementos podem ser monitorados? No conceito utilizado pelo OEM, os elementos que podem ser monitorados são chamados de Targets, e esses targets envolvem a monitoração de hosts (Windows, Linux, Solaris), Banco de Dados, Middleware, Aplicações Web, Serviços que podem ser customizados pelo administrador, Sistemas e Grupos de targets, além dos aplicativos Oracle. Cada elemento monitorado é ativado através de packs de gerenciamento. Ou seja, há uma série de packs que podem ser adquiridas conforme a necessidade, para permitir a monitoração a partir do próprio OEM Grid Control. Existem packs de monitoramento especiais para banco de dados Oracle, packs de monitoramento para Tomcat, Jboss, WebLogic, SOA Suite, Identity Management. A lista é bem extensa e darei mais detalhes em um novo post. Mas caso queira visitar, veja: http://download.oracle.com/docs/cd/B16240_01/doc/nav/overview.htm Além das packs de monitoramento, existem também plugins e conectores. Os plugins permitem o gerenciamento de elementos adicionais, tais como dispositivos de rede, servidores, banco de dados de terceiros (DB2, SQL Server), Vmware, etc. Já os conectores permitem a integração com outros softwares, tais como gerenciadores de requisições de helpdesk, de modo a integrar os alertas gerados pela ferramenta e gerar tickets em ferramentas como CA Service Desk, BMC Remedy e outros. A extensão de funcionalidades é realmente bem vasta. Num próximo post irei comentar sobre o Ops Center, um novo componente que surgiu após a aquisição da Sun. Além do Grid Control e do Ops Center, há outros componentes bem interessantes. A figura abaixo ilustra diversas camadas onde o ferramental Oracle pode ser usado para monitoração. Há uma pack que permite gerenciar os níveis de serviços em todas as camadas ilustradas. Dada uma requisição, pode-se decompor os dados de SLA em cada camada. E há também o Real User Monitoring, que trata de medir a experiência com o usuário. Falarei disso num novo post, mas basicamente a ferramenta permite acompanhar todo o tráfego de rede gerado dos usuários finais até os servidores web, e com isso rastrear como cada usuário usa a aplicação, quanto tempo ele navega pelo site, se ele enfrentou algum tipo de problema, se houve algum pedido não finalizado devido a algum problema na infraestrutura.
