In our sample application, we have a sixth and seventh connection at the end of the code, their connection request will be given from the connection pool. Name=SuperApp Workstation ID=SuperNova Pooling=true Connection Lifetime=100 Lifetime in the connection string and it determines how long a connection will be kept in the connection pool. Connection poolsĪre not destroyed until the active process ends or the connection lifetime is exceeded.
Names, authentication types, and other differences cause to generate different connection pools. Connections string dissimilarities cause to generate separate connection pools. The reason for the generation of two separate connection pools is the application name difference in the connection Many connections are managed in these pools. The parameter NumberOfActiveConnectionPools shows the number of connection pools and NumberOfPooledConnections shows how NET Framework Data Provider for SQL Server in PerfMon. This case can observe using performance counters of the. The first 3 connections will place in a connection pool and the second 2 connections will place another pool. When we run this console application it will generate 2 connection pools. Request 7 new connections and execute a very simple query. When the application sends a signal to close the connection, instead of closing the connection, the pool worker sends it to the connection pool. If the pool worker finds a connection according to matching criteria it returns this ready connection to this request. When a user requests a new connection with a matching connection string, the pooler looks for an available connection in the pool that corresponds to that connection string. The connection pool can be likened to a connection cache because in this working concept SQL SQL Server keeps ready to use in a pool instead of destroying the connections that their tasks have finished up. Name=SuperApp Workstation ID=SuperNova Pooling=true However, we can explicitly set this option in the connection string. Therefore, we don’t need to change anything to enable this option. The default setting of the connection pool is true, Therefore, SQL Server uses the connection pooling mechanism to get rid of this laborious task. Generating a new connection is a bit resource-intensive task for the SQL engine. SQL connection string and connection pooling Server=localhost Database=SQLShackDemo User Id=SuperHero Password=1pass Application In the following connection string, we will set the machine name as SuperNova. In a connection string, we can change the connecting machine name to use the Workstation ID attribute.
