What is a pre-requisite for connection pooling?

  
Multiple processes must agree that they will share the same connection, where every parameter is the same, including the security settings. (More...)

Does ADO.NET supports automatic connection pooling?

  
Yes.

There is a pooling property with connection string. By default it is set to true.
Use this property to specify that a particular connection should not participate in the pool, but instead should be destroyed when it is closed. (More...)

What is Connection Pooling ?

  
Connection Pooling will make a single connection instance, which allows that instance to connect to all the databases. Advantage is that it does not open and close the connection object multiple times. (More...)

What is Connection Pooling

  
Connection pooling is of

· A Connection Pool is a container of open and reusable connections. A Connection Pool is released from the memory when the last connection to the database is closed.

· The Data Providers in ADO.NET have Connection Pooling turned on by default; if you need to turn it off, specify Pooling = false in the connection string being used.

· Connection Pooling gives you an idle, open, reusable connection instead of opening a new one every time a connection request to the database is made. When the connection is closed or disposed, it is returned to the pool and remains idle until a request for a new connection comes in.

· The pool can house connections up to the maximum limit as specified in the connection string that was used to connect to the database.

Parameters used in Connection pooling

  
Connection Pooling is controlled and the parameters passed to a connection string comprises the following:

· Connect Timeout

· Min Pool Size

· Max Pool Size

· Pooling

(More...)

Adv and Disadv of using Connection Pooling

  
Advantage of using Connection Pooling is an improvement of performance and scalability

Disadvantage is that one or more database connections, even if they are currently not used, are kept open

What is connection pooling and what is the maximum Pool Size in ADO.NET Connection String?

  
A connection pool is created when a connection is opened the first time. The next time a connection is opened, the connection string is matched and if found exactly equal, the connection pooling would work.
Otherwise, a new connection is opened, and connection pooling won't be used.
Maximum pool size is the maximum number of connection objects to be pooled.
If the maximum pool size is reached, then the requests are queued until some connections are released back to the pool. It is therefore advisable to close the connection once done with it. (More...)

Explain in detail the fundamental of connection pooling?

  
ADO.NET with IIS uses a technique called connection pooling, which is very helpful in applications which regularly connecting to the database and accessing information on the server. In this if the database call is made for the first time the connection object is made, after release of connection that object is kept in pool and ADO.NET keeps reference to it. And next time when the request to execute any query/stored proc comes up, it bypasses the hefty process of establishing the connection and just picks up the connection from the connection pool and uses that for this database call. (More...)

Where do you store connection string?

  
Database connection string can be stored in the web config file.
The connection string can be stored in the WEB.Config file under
element. (More...)

What does connection string consist of?

  
The connection string consists of the following parts:
In general:

Server: Whether local or remote.

Uid: User Id (sa-in sql server)

Password: The required password to be filled-in here

Database: The database name. (More...)

How you will write a Connection String in web.Config fiel?

  
Ans) Then write below lines of code:

configuration>
connectionStrings>
add name="sqlconnectionstring" connectionString="Data Source=INTHIYAAZ;Initial Catalog=DB;User ID=sa;Password=sa" />
/connectionStrings>
/configuration>
