What is Connection Pooling in ASP.NET?

In previous articles, we have learned to encrypt and decrypt the connection string in web.config file. In this article, we will learn what is connection pooling? Why connection pooling useful? and what is the maximum limit & minimum limit of connection pooling?

Connection Pooling in ASP.NET

When we use ADO.NET in a c# application, the first thing we do is create a connection object and open the…

Can't Debug SharePoint Workflow

This is probably the toughest thing I've run up against yet with SharePoint. I won't share how much time was involved. shudder

I was not able to hit the breakpoints I added to my custom workflow in Visual Studio 2005. I attached to the w3wp.exe process s of type "Workflow", I compiled the dll in debug mode, I even made sure the appropriate .pdb resided in the same gac_msil directory as my assembly in the gac. Nothing.

Further frustrating the issue, and at the time unknowingly related, was the fact that once a workflow was initiated on a list item, it would give me the infamous "Failed On Start (Retrying)" error. I couldn't debug my workflow to see why it was failing to start. Argh.

Eventually I found this post here (Thank you Irfan Bashir!) , which suggested checking the "Policy for Web Application" section under Sharepoint Central Administration -> Application Management. Make sure your App Pool account for your SharePoint site (in my case "Network Service") has Full Control as opposed to just "Full Read". Restart IIS and try debugging your application again! This should get rid of at least any trouble you have hitting your breakpoints in Visual Studio.

Key IIS Measurements to Screen

Microsoft's Internet Information Services (IIS) is a web server that has customarily come packaged with Windows (e.g., variants 5.0, 6.0, and past). IIS has various extensibility highlights. Swappable interfaces like ISAPI and FastCGI make it conceivable to utilize IIS with an assortment of backend innovations, from small scale systems like Flask to runtimes like Node.js, alongside advances you'd hope to discover inside a Windows-based generation condition (e.g., ASP.NET). What's more, through an environment of IIS augmentations, called modules, you can prepare your server to perform assignments like revising URLs and automatically stack adjusting demands. IIS gives you a chance to enhance execution with inherent substance reserving and pressure includes, and enhance the unwavering quality of your applications by secluding them in isolated application pools.

In this post, we'll review IIS measurements that can enable you to guarantee the accessibility and execution of your web server. While we're concentrating on IIS 10, which is packaged with Windows Server 2016 and Windows 10, you can counsel the documentation in case you're utilizing a prior rendition and need to check whether something we talk about is accessible to you. And keeping in mind that IIS can actualize various TCP-based conventions, including FTP, we'll be focusing on IIS's default setup as a server for HTTP or HTTPS.

The structure of an IIS server

You'll need to sort out your checking system around the way that IIS's parts are spread out over various Windows procedures and drivers. We'll investigate these parts, at that point present the IIS measurements you'll need to use to screen them.

HTTP.sys and laborer forms

The laborer procedure directs the fundamental work of a web server: dealing with customer demands and serving reactions. IIS can deal with solicitations with numerous laborer forms at once (contingent upon your setup), every one of which keeps running as the executable w3wp.exe.

At the point when a demand achieves your Windows server, it goes through HTTP.sys, a portion mode gadget driver. HTTP.sys tunes in for HTTP and HTTPS asks for, and approves every one preceding passing it to a laborer procedure. On the off chance that no specialist procedure is accessible to deal with a demand, HTTP.sys places the demand in a portion mode line.

When checking traffic to HTTP.sys, you will probably be utilizing execution counters gathered by the World Wide Web Publishing Service (WWW Service), which keeps running as a component of an occasion of the procedure, svchost.exe. The WWW Service passes put away IIS arrangement settings to HTTP.sys, and gathers execution counters for every ii site.

Each laborer procedure has a place with an application pool, which keeps applications commonly segregated to enhance their accessibility—if an application crashes, it won't influence other application pools. Laborer forms in a single pool don't impart assets to different pools. You can pass arrangement settings to a solitary pool to, for example, throttle the CPU use of its specialists. Every application pool defaults to a solitary laborer process, and you can design your pools to incorporate more.

Assigning File Permission For ApplicationPoolIdentity in IIS 8

Everything was going fine after publishing a new web application to IIS 8 on Windows Server 2014. Then suddenly I saw few errors in logs like:

System.UnauthorizedAccessException Access to the path 'C:\inetpub\wwwroot\wodnerful-app\reports\Q1 2017.pdf' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode) at WonderfulApp.Controllers.Api.Reports.d__4.MoveNext()

The files were under root application folder. The application was running under ApplicationPoolIdentity in its own application pool.

I checked the permissions on folder for following principals/groups:

IIS_User

IUSR

Authenticated Users

Network Service

Well, all had the read and execute permissions.

Clearly the ApplicationPoolIdentity under which the website was running was not (or part of) anyone of the above.

I looked at it in Task Manager and it showed WonderfulApp as user running this (w3wp.exe) process.

It seemed straightforward at this point: go to the folder, right-click select Properties>Security>Advanced>Add>Select a principal> type user name in the box and click Check Names button.

But whatever I did, it was not getting the WonderfulApp user/principal that was shown in Task Manager.

After fiddling around and googling about it, I stumbled upon this answer on Severfault. It required to type IIS APPPOOL Yep those are 3 Ps before the WonderfulApp like this: IIS APPPOOL\WonderfulApp.

Giving appropriate permissions to IIS APPPOOL\WonderfulApp made it work

So in short, if your app is running under ApplicationPoolIdentity and you are not impersonating, your user name should be IIS APPPOOL\ApplictaionPoolName

Happy Coding!
