SQL Server 2008 R2 Hosting :: Tips How to Restore Database with SQL Server 2008 R2

clock June 28, 2013 07:38 by author Ben

SQL Server 2008 R2 delivers several breakthrough capabilities that will enable your organization to scale database operations with confidence, improve IT and developer efficiency, and enable highly scalable and well managed Business Intelligence on a self-service basis for your users.

This is the tips to restore your database in sql server 2008 :

You need to select the backups which you need to restore from the backup set list.



First, thing to notice here is, it takes a tail-log backup of the source database.
The Backup Sets list does not list all backup sets available in the media, it only lists backups of the selected database:



Also, it is showing only the latest backups since last FULL database backup, just like selecting database as source in earlier versions. Older backup can be restored via "Timeline…", which is self-explanatory:



And to make it complete, it also has a "Verify Backup Media" button. Enjoy it! :)



IIS 7.5 Hosting :: Configuring Pinging to Avoid Terminating Processes

clock June 17, 2013 14:01 by author Ben

IIS monitors the worker processes health by sending a periodic request the worker processes. This pinging is to ensure that if the worker processes responding the incoming requests in timely manner. If the worker process does not respond in a timely manner, IIS terminates the process after a specific number of ping.  Now, consider you are debugging your web application by attaching w3wp.exe from Visual Studio.  During debugging, it might take a long to find out result of debugging and as an out come, execution is on hold as you are pausing around with some breakpoints or playing around the code.

In between your debugging, IIS sending a ping to check worker process health and found it’s not responding, as you are holding the execution around breakpoint or other operation with in visual studio. Resulting of that, IIS terminates the process and you will get error message “The web server process that was being debugged has been terminated by Internet Information Services” .

Now think about it,  you are middle of a debugging session and the worker process process terminates. This will stop your entire debugging. This is quite frustrating and irritating when you are in a middle of debugging and debugger terminates because of the worker process.

Here is the solution:

Open the application pool from IIS Manager and navigate to “Advanced Settings” from the context menu of selected application pool.

This will open “Advanced settings” dialog window. Move to “Process Model” section

By default, you will find,

Ping Enabled = True with Ping Maximum Response Time = 90s and Ping Period = 30s

If worker process responding with in the specified time frame, IIS will keep the worker process alive. But considering the debugging time, the maximum response time is very less.

What you can do over here is, increase the Ping Maximum Response Time  with some values which can ensure worker process will get a response in between health check.

Or, Disable the Pinging by Ping Enabled = False  . By this setting IIS will stop pining your worker process for health checkup.

Note :  This is recommended only for your development environment.  Don’t disable it on Test, staging or Production environments. Worker process health monitoring, terminating processes when there is no timely request are very crucial for application performance.



Tip IIS 8.0 Hosting :: Enabling SSL on IIS 8.0 Using Self-Signed Certificates

clock June 10, 2013 12:27 by author Ben

SSL enables browsers to communicate with a web-server over a secure channel that prevents eavesdropping, tampering and message forgery.  You should always use SSL for login pages where users are entering usernames/passwords, as well as for all other sensitive pages on sites (for example: account pages that show financial or personal information). 

Configuring SSL on Windows with previous versions of IIS has been a pain.  Figuring out how to install and manage a certificate, and then associate it with a web-site, is something I bet most web developers don't know how to enable.

The good news is that IIS 8.0 makes it radically easier to configure and enable SSL.  IIS 8.0 also now has built-in support for creating "Self Signed Certificates" that enable you to easily create test/personal certificates that you can use to quickly SSL enable a site for development or test purposes. 

Using IIS 8.0 you can SSL enable an existing web site in under 30 seconds.  The below tutorial demonstrates how to-do this.

Step 1: Create a New Web Site

We'll start by creating a new web-site using the new IIS 8.0 admin tool.  This admin tool is a complete re-write of the previous IIS admin tool (and was written entirely in managed code using Windows Forms), and provides a more logical organization of web features.  It provides a GUI admin experience for all ASP.NET and IIS settings.

To create a new site on the box, right click on the "Web Sites" node in the left hand tree-view pane and choose the "Add Web Site" context menu option.  Enter the appropriate details to create a new web-site:

One nice feature of IIS on Windows Vista is that you can now have an unlimited number of sites on a box (previous versions of IIS on Windows Client only allowed 1 site).  The 10 simultaneous request limitation on Windows Client versions of IIS also no longer exists with IIS 8.0.

Once we've completed the above steps, we will now have a brand new site running on our IIS web-server.

Step 2: Create a new Self Signed Certificate
Before binding SSL rules to our new site, we need to first import and setup a security certificate to use with the SSL binding. 

Certificates are managed in IIS 8.0 by clicking the root machine node in the left-hand tree-view explorer, and then selecting the "Server Certificates" icon in the feature pane on the right:

This will then list all certificates registered on the machine, and allow you to optionally import and/or create new ones.

I could optionally go to a certificate authority like Verisign and purchase a certificate to import using this admin UI.  Alternatively, I can create a "self-signed certificate" which is a test certificate that I can use during the development and testing of my site.  To-do this, click the "Create Self-Signed Certificate" link on the right-hand side of the admin tool:

Enter a name to use for the certificate (for example: "test") and hit ok.  IIS8 will then automatically create a new self-signed crypto certificate for you and register it on the machine:

Step 3: Enable HTTPS Bindings for our New Site
To SSL enable the web-site we created earlier, select the web-site node in the left-hand tree-view, and the click the "Bindings" link in its "actions" pane on the right-hand side of the screen:

This will then bring up a dialog that lists all of the binding rules that direct traffic to this site (meaning the host-header/IP address/port combinations for the site):

To enable SSL for the site, we'll want to click the "Add" button. This will bring up an "add binding" dialog that we can use to add HTTPS protocol support.  We can select the self-signed certificate we created earlier from the SSL certificate dropdownlist in the dialog, and in doing so indicate that we want to use that certificate when encrypting content over SSL:

Click ok, and we now have SSL enabled for our site:

Step 4: Test out the Site
Add a "default.aspx" page to the site, and then try and hit it with the browser by typing https://localhost/default.aspx (note the usage of "https" instead of "http" to indicate that you want to connect over SSL).

If you are using IE8, you'll likely see this anti-phishing error message kick in

Don't panic if this happens - it is just IE being helpful by suggesting that a self-signed certificate on your local machine looks suspicious. Click the "Continue to this website" link to bypass this security warning and proceed to the site.  You'll find that your default.aspx page is now running protected via SSL:

You are all done. :-)

Appendix: A Few Last SSL Notes
A few last SSL related notes:
The IIS 8.0 admin tool has an "SSL Settings" node that you can select for each site, directory or file that allows you to control whether that particular resource (and by default its children) requires an SSL request in order to execute.  This is useful for pages like a login.aspx page, where you want to guarantee that users can only enter their credentials when they are posting via an encrypted channel. If you configure the login.aspx page to require SSL, IIS 8.0 will block browsers from accessing it unless they are doing so over SSL.

Within an ASP.NET page or handler, you can programmatically check whether the current request is using SSL by checking the Request.IsSecure property (it will return "true" if the incoming browser request is over SSL).

You can set the "requireSSL" attribute on the <forms> configuration section within web.config files to have ASP.NET's forms-authentication system ensure that forms-authentication cookies are only set and used on SSL enabled pages and URLs.  This avoids the risk of a hacker trying to intercept the authentication cookie on a non-SSL secured page, and then trying to use a "replay attack" from a different machine to impersonate a user.



Visual Studio Tip :: Configure Code Analysis in Visual Studio

clock June 7, 2013 07:53 by author Ben

I like well-written code, and I especially like it when I've written it. But I don't always live up to my own expectations. So I've used various tools (FxCop, CodeRush, ReSharper) to give me some objective feedback on the quality of my code. Starting with Visual Studio 2010, Microsoft built the latest version of their tools into Visual Studio: Visual Studio 2012 Ultimate (and up) and Visual Studio 2012 Professional (and up). From Visual Studio's Analyze menu, you can select Run Code Analysis on individual projects or on your whole solution.

The code analysis tools will report on whether your code reflects best practices, based on a set of Microsoft's rules. You should realize, however, that just because Microsoft has a specific rule, it doesn't mean that you should write your code according to that rule.

For instance, Microsoft expects all of its projects to use the CLSCompliant attribute. This attribute causes the compiler to check for issues that would prevent your code's external API from being compatible with other .NET Framework code.

For instance, it's perfectly OK in C# to have two public methods with the same name but with different upper and lower case letters (e.g. Update() and uPDATE()). However, those method names would be indistinguishable in Visual Basic, which is why they would violate the CLSCompliant attribute.

However, you probably don't need the CLSComplaint attribute because (a) you're a single language shop, and (b) you probably wouldn't do anything that violates the CLSCompliant attribute anyway (I mean, really: Update and uPDATE?)

It's important, therefore, from the Analyze menu to select the Configure Code Analysis choice and pick the right rule set for you. The Microsoft All Rules choice is almost certainly not the choice you want. Instead, select the <Choose Multiple Rule Sets> option and check off the rule sets that appeal to you. This will let you, over time, remove the rule sets that flag issues you're not interested in.

If you're really committed, consider adding and removing rules from the rulesets themselves. To do that, from the File menu select Open | File and navigate to the folder that the ruleset files are kept in (For my installation of Visual Studio 2012, that's C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Static Analysis Tools\Rule Sets\). Opening a ruleset file in Visual Studio will allow you to check off which rules in the ruleset you want to keep and which you want to ignore.
