Where we need to provide the file name and location. If we want, we can set a password to encrypt the XML file. Below is a part of that XML:. Now we can create a new application pool for this configuration file.
While creating a new application pool, we have to select the "Application Pool From File " option as shown in the below figure. When we select this option, a screen will come where we need to enter the file name and the password of that file. Select the file and click on the "Read File" button.
This will show you the imported application pool name. Click "OK" to import the full configuration. Here we need to mention the new application pool name or we can have another option where we can replace an existing application pool.
For moving ahead, we need to provide the password. This is one of the most important tasks for web server configuration and this is important when we are hosting on a production server.
As I have already discussed, the application pool is the heart of any web application hosted on IIS. We need to know each and every configuration of the application pool.
To start configuration, we need to go to the Properties of the application pool. Recycling the application pool means recycling the worker process w3wp. It is a very good practice to recycle the worker process periodically, which wll keep the application running smooth. There are two types of recycling related with the application pool:. Worker process recycling is the replacing of the instance of the application in memory. This improves web site performance and keeps web sites up and running smoothly.
We can set a specific time period after which a worker process will be recycled. IIS will take care of all the current running requests. We can configure an application with a given number of requests. Once IIS reaches that limit, the worker process will be recycled automatically. If we want to recycle the worker process at any given time, we can do that configuration on IIS.
We can also set multiple times for this. Server memory is a big concern for any web application. Sometimes we need to clean up a worker process based on the memory consumed by it. There are two types of settings that we can configure in the application pool to recycle a worker process based on memory consumption. These are:. At any time, if the worker process consumes the specified memory at memory recycling settings , it will be recycled automatically.
This is quite an interesting question. Based on the above settings, an application pool can be recycled any time. So what happens to the users who are accessing the site at that time? We do not need to worry about that. This process is transparent from the client. When you recycle an application pool, HTTP. SYS holds onto the client connection in kernel mode while the user mode worker process recycles.
After the process recycles, HTTP. SYS transparently routes the new requests to the new worker process. To improve the performance of a web application, we can setup the performance settings of the application pool. We can set the shut down time of the worker process based on the ideal time. The worker process will be shut down at a given time period if it is ideal. Whenever a new requests comes, it will live again. Another important thing for improving the performance is "Web Garden".
By default, each application pool runs with a single worker process W3Wp. We can assign multiple worker processes with a single application pool. An application pool with multiple worker processes is called a Web Garden.
Many worker processes with the same application pool can sometimes provide better throughput performance and application response time. And each worker process should have its own thread and memory space. As Shown in the picture, in IIS Server, there may be multiple application pools and each application pool has at least a single worker process.
A Web Garden should contain multiple worker processes. There are certain restrictions in using a Web Garden with your web application. If we use Session Mode as "in proc", our application will not work correctly because the Session will be handled by a different worker process.
Main advantage : The worker processes in a web garden share the requests that arrive for that particular application pool. If a worker process fails, another worker process can continue processing the requests. Now we move to the "Health" tab. When wel select the "Health" tab, it will show the following screen:. IIS provides a couple of settings to improve the health of an application pool.
There are also a few settings for measuring the worker process health. This property specifies whether the WWW Publishing Service should periodically monitor the health of a worker process. Checking this option indicates to the WWW service to monitor the worker processes to ensure that worker processes are running and healthy. By default, it sets to 30s. This is also needed to check if a service is staying ideal or not.
If it is ideal it can be shutdown until the next request comes. The Windows Activation Process maintains all this stuff. When enabling Rapid Fail Protection, the application pool is shut down if there are a specified number of worker process crashing within a specified time period. When this happens, the WWW Publishing Service puts all applications in the application pool "out of service". Failure Count : The default value for failure count is 5 minutes.
This property specifies the maximum number of failures allowed within the number of minutes specified by the "Time Period" property before the application pool is shut down by Rapid Fail Protection. If the number of failure is more than the specified in a given time, the application pool should be put on "out of service mode". Time period : This property specifies the number of minutes before the failure count for a process is reset. By default, it is set to 5 minutes.
In general it means the time taken to start a worker process. This is the shutdown time for a worker process. This is the time required to execute all old running worker process requests before it shuts down during recycle time. This is the last and final setting for an application pool. An application pool has three types of identity: "Network Service" is the default Identify. Below are the listed application pool identities with description:. We can also configure the application pool under a given user account.
For that, we need to select the "Configurable" option on "Identity" tab. Sign in to vote. Recently we have purchased new server with Windows Server OS. Since we still don't know how to properly configure IIS 7. Thank you. Sunday, July 6, AM. User posted You can't install IIS 6 on w2k8. Monday, July 7, AM. Is this a new feature? Saturday, January 3, AM. User posted It's not possible to have IIS 6 and 7 on the same box.
Saturday, January 3, PM. User posted Yes, that is exactly what it really is. I just verified that with my hosting company. User posted No offense taken. Saturday, June 27, AM. User posted Hello Gabriel, sorry for ask this, but how in this world you get IIS 6 installed on Windows ???
