When using a Web garden, it is important to understand the way the session state and the looping work are done. It is also important to consider how other application pool settings affect your application.
Session state in a network garden using worker process isolation mode
When using session state, be aware that worker process isolation mod
configuration, and many examples of open source and Tomcat applications are used for this connection pool.This connection pool can set the maximum and minimum connections, connection waiting time, etc., basic functions are available. The configuration of this connection
Because applications in the application pool are separated from other applications by working process boundaries, applications in an application pool will not be affected by problems caused by applications in other application pools.
Windows 2003 supports two working modes at the same time. The default is ISS 6.0 Working Process Isolation Mode. Working Process Isolation Mode prevents one application or sit
(including asp.net and asp.dll) can declare that they are no longer suitable for service and require recycling.
By default, when IIS 6.0 reclaims a pool, it uses a recycling technique called overlapped recycle. In this recycling mode, the failed worker process remains running while a new worker process is created. IIS 6.0 passes the new incoming request to the n
system resources, and setting too small will cause frequent 503 errors during client access.

Let's take a look at the sqlconnection string parameters of ado.net.
We have set the maximum and minimum pools. How can we see the differences between Windows app and web appp?
We can create a web application or Windows app. After the app is enabled, you can use sp_who2 in the SQL analyzer to view the connected client, obviously, if a web application or Windows app starts n connections
network garden in the auxiliary process Isolation Mode
When using the session Status, note that the auxiliary process Isolation Mode does not support sending requests back to the process that causes the request to return. When an application is running in an ASP session or application network, the application needs to send its request back to the initiated process. When using IIS 6.0Application poolMake sure that the application keeps a
data providers, it uses the pool mechanism internally, so you no longer need to develop your own object pool mechanism (when using the provider ). Therefore, you can avoid complex tasks associated with manual transaction registration.
Monitoring connection pool
1) SQL Serv
In practice, we often encounter areas where pooling is needed, especially database connection pooling.Why do we need a pool? Because these resources are created, resources are consumed. Therefore, we use an object pool, which is pre-created with some resource objects. When we need to, we pull the object out of the pool
System Monitor chart area (you can set the parameters such as color and width), which is the number of IIS connections to the site, as shown in the yellow curve.
What you need to know is that Windows System Monitor displays the number of instant IIS concurrent connections, not the number of visitors within 15 minutes of "site statistics", so you'll find that there are not too many
The monitoring server is a critical part of server management. By using the appropriate monitoring tools, you can detect server problems, evaluate the results of changes to site content, and plan upgrades to facilitate user access to the site. Select the appropriate monitoring tools and methods based on the information you need.
You can also monitor the server by
