• WAIT-VHUB ? Whats Going On ?

  - by Neeraj Gupta

  I know many of you have been working on Oracle's Exalogic and other Engineered Systems. With partitions enabled now, things have gone multi dimension. But its fun. Isn't it ? While you have some EoIB configurations together with InfiniBand partitions, the VNICs are not coming up and staying in WAIT-VHUB state ?  Chances are that you have forgot to add InfiniBand Gateway switches' Bridge-X port GUIDs to your partition. These must be added as FULL members for EoIB to work properly. VHUB means a virtual hub in EoIB. Bridge-x is the access point for hosts to work over EoIB so thats why it must be a full member in partition. Step 1: Find out the port GUIDs of your bridge-x devices in IB Gateway switch. # showgwports INTERNAL PORTS: --------------- Device   Port Portname  PeerPort PortGUID           LID    IBState  GWState --------------------------------------------------------------------------- Bridge-0  1   Bridge-0-1    4    0x0010e00c1b60c001 0x0002 Active   Up Bridge-0  2   Bridge-0-2    3    0x0010e00c1b60c002 0x0006 Active   Up Bridge-1  1   Bridge-1-1    2    0x0010e00c1b60c041 0x0026 Active   Up Bridge-1  2   Bridge-1-2    1    0x0010e00c1b60c042 0x002a Active   Up Step 2: Add these port GUIDs to the IB partition associated with EoIB. Login to master SM switch for this task. # smpartition start # smpartition add -pkey <PKey> -port <port GUID> -m full # smpartition commit Enjoy !

  If you facing the issue that the web Analytics Reports in SharePoint 2010 Central Administration is not updating data. When you go to your site > site settings > Site Web Analytics reports or Site Collection Analytics reports  You get old data as in the ribbon displayed "Data Last Updated: 12/13/2010 2:00:20 AM" Please insure that the following things are covered: Insure that Usage and Data Health Data Collection service is configured correctly. Log Collection Schedule is configured correctly Microsoft Sharepoint Foundation Usage Data Import and Microsoft SharePoint Foundation Usage Data Processing Timer jobs are configured to run at regular intervals One last important Timer job is the Web Analytics Trigger Workflows Timer Job insure that this timer job is enabled and scheduled to run at regular intervals (for each site that you need analytics for). After you have insured that the web analytics service configuration is working fine and the Usage Data Import job is importing the *.usage files from the ULS LOGS folder into the WSS_Logging database, and that all the required timer jobs are running as expected… wait for a day for the report to get updated… the report gets updated automatically at 2:00 am in the morning… and i could not find a way to control the schedule for this report update job. So be sure to wait for a day before giving up :)

• Doubt regarding search engine/plugin(One present on the website itself)

  - by Ravi Gupta

  I am new to web development and trying to study various types of websites as case study. Right now my focus is on how search engines works for an eCommerce website. I know basic functioning for a search engine, i.e. crawl web pages, index them and the display the results using those indexes. But I got little confuse in case of an eCommerce website. Don't you think that it would be better if a search engine instead of crawling the web pages containing products, it should directly crawl the database and index the products stored in the database? And when a user search for any product, it will simply give us the rows of the table which matches the user query? If this is not the case, can someone please explain how the usual method works on eCommerce website?

• How to set Qwt path to the run-time linker in Xubuntu

  - by Rahul

  I've successfully installed Qwt in Xubuntu 12.04(qmake - make - make install). But now I need to set the Qwt path to run time linker of Xubuntu. In manual it's given like - If you have installed a shared library it's path has to be known to the run-time linker of your operating system. On Linux systems read "man ldconfig" ( or google for it ). Another option is to use the LD_LIBRARY_PATH (on some systems LIBPATH is used instead, on MacOSX it is called DYLD_LIBRARY_PATH) environment variable. But being newbie to Linux environment, I'm not able to proceed further. Please help me with this.

• Hosting advice for a write-heavy dynamic website

  - by Rahul Rawat

  I have built a website using PHP and MySQL and now I am looking for a hosting service. I am expecting about a 1000 users registering and about 5-10k pageviews/day in a week's time. So which host should I opt for? It will let users submit contents of type blobs and submit around 10 pictures per users. I hope that traffic will increase so can justhost's or bluehost's shared hosting serve that purpose or should I go for more dedicated ones. Basically the site is write heavy and there are average 2-3 MySQL queries per page and it is quite dynamic. So depending on these requirements which web hosting will be optimal for me.

• NHibernate Session Load vs Get when using Table per Hierarchy. Always use ISession.Get&lt;T&gt; for TPH to work.

  - by Rohit Gupta

  Originally posted on: http://geekswithblogs.net/rgupta/archive/2014/06/01/nhibernate-session-load-vs-get-when-using-table-per-hierarchy.aspxNHibernate ISession has two methods on it : Load and Get. Load allows the entity to be loaded lazily, meaning the actual call to the database is made only when properties on the entity being loaded is first accessed. Additionally, if the entity has already been loaded into NHibernate Cache, then the entity is loaded directly from the cache instead of querying the underlying database. ISession.Get<T> instead makes the call to the database, every time it is invoked. With this background, it is obvious that we would prefer ISession.Load<T> over ISession.Get<T> most of the times for performance reasons to avoid making the expensive call to the database. let us consider the impact of using ISession.Load<T> when we are using the Table per Hierarchy implementation of NHibernate. Thus we have base class/ table Animal, there is a derived class named Snake with the Discriminator column being Type which in this case is “Snake”. If we load This Snake entity using the Repository for Animal, we would have a entity loaded, as shown below: public T GetByKey(object key, bool lazy = false) { if (lazy) return CurrentSession.Load<T>(key); return CurrentSession.Get<T>(key); } var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), true); var snake = animal as Snake; snake is null As you can see that the animal entity retrieved from the database cannot be cast to Snake even though the entity is actually a snake. The reason being ISession.Load prevents the entity to be cast to Snake and will throw the following exception: System.InvalidCastException :  Message=Unable to cast object of type 'TPHAnimalProxy' to type 'NHibernateChecker.Model.Snake'. Thus we can see that if we lazy load the entity using ISession.Load<TPHAnimal> then we get a TPHAnimalProxy and not a snake. =============================================================== However if do not lazy load the same cast works perfectly fine, this is since we are loading the entity from database and the entity being loaded is not a proxy. Thus the following code does not throw any exceptions, infact the snake variable is not null: var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), false); var snake = animal as Snake; if (snake == null) { var snake22 = (Snake) animal; }

  I am leading a QA team of 10 people. we have been received the request for a training of a ETL dataware housing tool for QA, Support and Development. But however the management does not feel that it is important for QA to be involved in such a training as it is support and development team who will be involved ih developing or fixing the issues in the product. How do I convince the management that this training is very important from the QA perspective as this is the team that will find bugs and which will reduce the maintainance cost?

• What can I do to encourage teams to lighten up? [closed]

  - by Rahul

  I work with a geographically distributed team (different timezones) with people from various cultures and background. Some of us have never met each other in person but we communicate with each other over phone, chat and email almost on an hourly basis. Most of our meetings and discussions are dead serious and boring. What's worse, any attempt at humor is not very well received because of cultural differences. I feel that we are all taking our work a bit too seriously. We don't shy away from painful arguments, nasty emails and heated discussions when things go wrong but never attempt to develop camaraderie or friendships in better times. I would like to know your experiences with such situations and what, if anything, did you do to lighten things up at workplace.

  - by Rahul Shivsharan

  I have an experience in Java language and in JEE related Framework for about 5 years. In these 5 years i have worked on Core java, Spring, Hibernate, JPA, Struts 1. Now just to be prepared for the near future, i am thinking to learn some new programming language or some new technology, this will help me out to be a more elligible employee. So my question to you is, which new technology or language should i learn, my target is for next 3 years. So just in case if Java fades out (thought it won't) than i can jump on to this newly learned stuff. Where should i start from ? Should i learn some other language in JVM like Scala, Clojure, Groovy, JRuby ? Or should i learn some altogether different language like Python or Erlang, Perl ? Or new technology which is related to NoSQL, like MongoDB, Hadoop, CouchDB. Or learn few current happening things in market like RoR, Node.js, LessCss or Sass, Coffee Script ?

• Ubuntu 12.04 Battery problem

  - by Rahul

  I have my laptop ( Dell Inspiron 14R) on dual boot with Ubuntu 12.04 and Windows 7. While using Windows 7, I used to get about 2.5-3 hours on battery fully charged (with my cellphone connected for 3g Internet). The battery is almost 2 years old. But in Ubuntu 12.04, I'm getting only about 1-1.5 hrs on battery. I tried installing jupiter, also tried some tweaks that were mentioned in the forums, like editing the grub file. But nothing seems to work. I am not sure if any app is draining the battery. The one application that I use always is firefox. It's always open. Is there any way I could get at least 2.5 hrs of battery time?

• Change AccountName/LoginName for a SharePoint User (SPUser)

  - by Rohit Gupta

  Consider the following: We have an account named MYDOMAIN\eholz. This accounts Active Directory Login Name changes to MYDOMAIN\eburrell Now this user was a active user in a Sharepoint 2010 team Site, and had a userProfile using the Account name MYDOMAIN\eholz. Since the AD LoginName changed to eburrell hence we need to update the Sharepoint User (SPUser object) as well update the userprofile to reflect the new account name. To update the Sharepoint User LoginName we can run the following stsadm command on the Server: STSADM –o migrateuser –oldlogin MYDOMAIN\eholz –newlogin MYDOMAIN\eburrell –ignoresidhistory However to update the Sharepoint 2010 UserProfile, i first tried running a Incremental/Full Synchronization using the User Profile Synchronization service… this did not work. To enable me to update the AccountName field (which is a read only field) of the UserProfile, I had to first delete the User Profile for MYDOMAIN\eholz and then run a FULL Synchronization using the User Profile Synchronization service which synchronizes the Sharepoint User Profiles with the AD profiles. Update: if you just run the STSADM –o migrateuser command… the profile also gets updated automatically. so all you need is to run the stsadm –o migrate user command and you dont need to delete and recreate the User Profile

• In what ways can I test an image slideshow javascript code?

  - by Rahul

  I have a slideshow of images (and links) on a page. These images are part of a JSON response to a request sent after the page loads. The slideshow is set to play at an interval of 2 seconds. The slideshow can be paused, played over, and all other controls a normal slideshow would have. As a Rails dev, I proposed cucumber but the javascript guys in the team are not comfortable with ruby. I saw some cucumber for javascript libraries coming up, still in experimental stage. I checked out jasmine and related tutorials but all I could get from them is how I can carry out any internal functional testing such as credit-cart validation, etc. - which I think could actually be handled in unit testing? (Screw the research I did and) How should I go about testing this and similar components?

As with any Devoxx conference, this UK edition will have a nice mix of content, an impressive list of speakers and obviously Java EE will be well will covered too:  Apache TomEE, Java EE Web Profile and more on Tomcat (David Blevins) Myths, Tales and Voodoo - About Java EE and Testing (Adam Bien) 50 new features of Java EE 7 (Antonio Goncalves & Arun Gupta) Java EE 7 Hands-on Lab (Arun Gupta) In addition, there will be 2 BoF related to Java EE on Thursday evening, the first BoF will be about the Java EE platform and the second one will be about the Java EE Reference Implementation, i.e. GlassFish. I will participate in the Java EE Community BoF where will discuss Java EE general but with all recent activities, I suspect that a large portion of the BoF will spent on discussing the current plans for Java EE 8.  Right after and in the same room, I will join Steve Millidge of C2B2 for the GlassFish is here to stay! BoF. The goal is to discuss on GlassFish, the current status, the plans for the next release, how the community can contributes, etc. It should be mentioned that attending those BoFs is completely free, just make sure to register here.  So if you are in London next week, mind the Geek and see you at Devoxx UK!
