    Part1 of building my own development SharePoint2010 Farm Part2 of building my own development SharePoint2010 Farm Part3 of building my own development SharePoint2010 Farm In my last post, I have installed SharePoint2010 in one of the server (WFE One) and configured using the OOB SharePoint configuration wizard. In this post I will show you how to use OOB windows network load balancing to distribute load for SharePoint2010 site. 1. Install SharePoint in another server WFE Two (you can follow the steps in my last post), but instead of choosing create new Farm, you need to select “connect to existing farm” this time. 2. Click next then click retrieve database names button and select the farm configuration database. 3. Click next and enter the passphrase you specified when you first installed the SharePoint Farm. 4. Click the advanced settings and select Use this machine to host the web site. 5. Click OK to finish the configurations 6. Next, Install NLB in the two WFE (web front end) SharePoint servers 7. Configure NLB to create the cluster. Go to Start—Administrative Tools—Network Load Balancing Manager 8. Right-click the Network Load Balancing Clusters Node and select New Cluster. 9. Type in the host name that is to be part of the new cluster. 10. Type in the IP address for the cluster. 11. Select the Multicast for this cluster.(The default one is Unicast) 12. You can configure the Port Rules for the clustering , but I will leave the default here. 13. Add another WEF to the cluster. 14. Type in the host name that is to be part of the new cluster. 15. Set the Priority to 2. 16. Click Next to complete the cluster setup. 17. Create an entry in the DNS for the new cluster. 18. Add the binding to the IIS site in the IIS Manager 19.

  • Apache doesn't load .php files

    - by Haddex
    First, sorry for my English and asking something that it's quite answered all over the web. I've read a lot of post about this problem but I still can't find the solution. I'm a web developer who recently moved to Ubuntu from Windows 7. I had a website done (it's online and working) and I set up LAMP to keep working with it. I made a test.php file with: <?php phpinfo(); ?> and put it on /var/www/html directory, it shows all the information about the php and I was really happy: "Ok, it's all done, tomorrow I will work hard" But I placed my whole web into /var/www/html , not in a folder, the index.php is in /var/www/html but guess what: doesn't load any of my .php files, the browser just keep thinking. What I did: I rebooted Apache: /etc/init.d/apache2 restart I tried again with the test.php file and it works fine I put in /var/www/html a .html file and works fine. I looked for /etc/apache2/sites-enable/000-default.conf and it says: DocumentRoot /var/www/html I looked for /etc/apache2/mods-enabled/dir.conf and it says: DirectoryIndex index.html index.cgi index.pl index.php ... Edit* I think it's something related to phpmyadmin, like if I'm not able to connect with the database. But I got nothing on the screen when trying to load the page so...I'm not sure. I can access to the url localhost/phpmyadmin and I edited the connection.php file like this: <?php # FileName="Connection_php_mysql.htm" # Type="MYSQL" # HTTP="true" $hostname_rakstadconnection = "localhost"; $database_rakstadconnection = "rakstadclandb"; $username_rakstadconnection = "root"; $password_rakstadconnection = "admin"; $rakstadconnection = mysql_connect($hostname_rakstadconnection, $username_rakstadconnection, $password_rakstadconnection) or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("SET NAMES 'utf8'"); ?> The name of the database is correct, like the user and password. http://i89.photobucket.com/albums/k220/Haddex/Capturadepantallade2014-06-09112609_zpsc45ddb72.png http://i89.photobucket.com/albums/k220/Haddex/Capturadepantallade2014-06-09112120_zps0b9e15f7.png *Edit2: could this be because it's a website that I brought to Linux from Windows? I used Dreamweaver. Edit3: I changed the # to /*/, nothing. The error.log file says: [Mon Jun 09 17:08:13.627881 2014] [:error] [pid 1517] [client 127.0.0.1:46663] PHP Warning: require_once(/var/www/html/Connections/rakstadconnection.php): failed to open stream: Permission denied in /var/www/html/index.php on line 1 [Mon Jun 09 17:08:13.627933 2014] [:error] [pid 1517] [client 127.0.0.1:46663] PHP Fatal error: require_once(): Failed opening required 'Connections/rakstadconnection.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/html/index.php on line 1 I'm reading error log but...should I add a linux path into a my index.php file? Don't think so. Thanks.

  • Metrics - A little knowledge can be a dangerous thing (or 'Why you're not clever enough to interpret metrics data')

    - by Jason Crease
    At RedGate Software, I work on a .NET obfuscator  called SmartAssembly.  Various features of it use a database to store various things (exception reports, name-mappings, etc.) The user is given the option of using either a SQL-Server database (which requires them to have Microsoft SQL Server), or a Microsoft Access MDB file (which requires nothing). MDB is the default option, but power-users soon switch to using a SQL Server database because it offers better performance and data-sharing. In the fashionable spirit of optimization and metrics, an obvious product-management question is 'Which is the most popular? SQL Server or MDB?' We've collected data about this fact, using our 'Feature-Usage-Reporting' technology (available as part of SmartAssembly) and more recently our 'Application Metrics' technology: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 28 19.0 8115 8115 MDB 114 77.6 1449 1449 (As a disclaimer, please note than SmartAssembly has far more than 132 users . This data is just a selection of one build) So, it would appear that SQL-Server is used by fewer users, but more often. Great. But here's why these numbers are useless to me: Only the original developers understand the data What does a single 'usage' of 'MDB' mean? Does this happen once per run? Once per option change? On clicking the 'Obfuscate Now' button? When running the command-line version or just from the UI version? Each question could skew the data 10-fold either way, and the answers only known by the developer that instrumented the application in the first place. In other words, only the original developer can interpret the data - product-managers cannot interpret the data unaided. Most of the data is from uninterested users About half of people who download and run a free-trial from the internet quit it almost immediately. Only a small fraction use it sufficiently to make informed choices. Since the MDB option is the default one, we don't know how many of those 114 were people CHOOSING to use the MDB, or how many were JUST HAPPENING to use this MDB default for their 20-second trial. This is a problem we see across all our metrics: Are people are using X because it's the default or are they using X because they want to use X? We need to segment the data further - asking what percentage of each percentage meet our criteria for an 'established user' or 'informed user'. You end up spending hours writing sophisticated and dubious SQL queries to segment the data further. Not fun. You can't find out why they used this feature Metrics can answer the when and what, but not the why. Why did people use feature X? If you're anything like me, you often click on random buttons in unfamiliar applications just to explore the feature-set. If we listened uncritically to metrics at RedGate, we would eliminate the most-important and more-complex features which people actually buy the software for, leaving just big buttons on the main page and the About-Box. "Ah, that's interesting!" rather than "Ah, that's actionable!" People do love data. Did you know you eat 1201 chickens in a lifetime? But just 4 cows? Interesting, but useless. Often metrics give you a nice number: '5.8% of users have 3 or more monitors' . But unless the statistic is both SUPRISING and ACTIONABLE, it's useless. Most metrics are collected, reviewed with lots of cooing. and then forgotten. Unless a piece-of-data could change things, it's useless collecting it. People get obsessed with significance levels The first things that lots of people do with this data is do a t-test to get a significance level ("Hey! We know with 99.64% confidence that people prefer SQL Server to MDBs!") Believe me: other causes of error/misinterpretation in your data are FAR more significant than your t-test could ever comprehend. Confirmation bias prevents objectivity If the data appears to match our instinct, we feel satisfied and move on. If it doesn't, we suspect the data and dig deeper, plummeting down a rabbit-hole of segmentation and filtering until we give-up and move-on. Data is only useful if it can change our preconceptions. Do you trust this dodgy data more than your own understanding, knowledge and intelligence?  I don't. There's always multiple plausible ways to interpret/action any data Let's say we segment the above data, and get this data: Post-trial users (i.e. those using a paid version after the 14-day free-trial is over): Parameter Number of users % of total users Number of sessions Number of usages SQL Server 13 9.0 1115 1115 MDB 5 4.2 449 449 Trial users: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 15 10.0 7000 7000 MDB 114 77.6 1000 1000 How do you interpret this data? It's one of: Mostly SQL Server users buy our software. People who can't afford SQL Server tend to be unable to afford or unwilling to buy our software. Therefore, ditch MDB-support. Our MDB support is so poor and buggy that our massive MDB user-base doesn't buy it.  Therefore, spend loads of money improving it, and think about ditching SQL-Server support. People 'graduate' naturally from MDB to SQL Server as they use the software more. Things are fine the way they are. We're marketing the tool wrong. The large number of MDB users represent uninformed downloaders. Tell marketing to aggressively target SQL Server users. To choose an interpretation you need to segment again. And again. And again, and again. Opting-out is correlated with feature-usage Metrics tends to be opt-in. This skews the data even further. Between 5% and 30% of people choose to opt-in to metrics (often called 'customer improvement program' or something like that). Casual trial-users who are uninterested in your product or company are less likely to opt-in. This group is probably also likely to be MDB users. How much does this skew your data by? Who knows? It's not all doom and gloom. There are some things metrics can answer well. Environment facts. How many people have 3 monitors? Have Windows 7? Have .NET 4 installed? Have Japanese Windows? Minor optimizations.  Is the text-box big enough for average user-input? Performance data. How long does our app take to start? How many databases does the average user have on their server? As you can see, questions about who-the-user-is rather than what-the-user-does are easier to answer and action. Conclusion Use SmartAssembly. If not for the metrics (called 'Feature-Usage-Reporting'), then at least for the obfuscation/error-reporting. Data raises more questions than it answers. Questions about environment are the easiest to answer.

  • Avoid SQL Injection with Parameters

    - by simonsabin
    The best way to avoid SQL Injection is with parameters. With parameters you can’t get SQL Injection. You only get SQL Injection where you are building a SQL statement by concatenating your parameter values in with your SQL statement. Annoyingly many TSQL statements don’t take parameters, CREATE DATABASE for instance, or really annoyingly ALTER USER. In these situations you have to rely on using QUOTENAME or REPLACE to avoid SQL Injection. (Kimberly Tripp takes about this in her recent blog post Little...(read more)

  • Accessing SQL Server data from iOS apps

    - by RobertChipperfield
    Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

  • SpringMvc java.lang.NullPointerException When Posting Form To Server [closed]

    - by dev_darin
    I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException ValidateUserNameManager.java public class ValidateUserNameManager implements ValidateUserNameIFace { private OfficersDAO officerDao;
