What is connection pooling in IIS?
Connection pooling allows you to reuse connections rather than create a new one every time the ADO.NET data provider needs to establish a connection to the underlying database. Connection pooling behavior can be controlled by using connection string options (see the documentation for your data provider).
What is connection pooling?
Connection pooling means that connections are reused rather than created each time a connection is requested. To facilitate connection reuse, a memory cache of database connections, called a connection pool, is maintained by a connection pooling module as a layer on top of any standard JDBC driver product.
How many connections IIS can handle?
By default IIS 8.5 can handle 5000 concurrent requests as per MaxConcurrentRequestsPerCPU settings in aspnet. config. In machine. config, the maxconnection is 2 per CPU as default.
How do I check my connection pool?
Open the ODBC Data Source Administrator in Control Panel → Administrative Tools. Select the Connection Pooling tab. Ensure that the PerfMon Enable checkbox is checked. Start Performance Monitor by selecting Start → All Programs → Administrative Tools → Performance.
How does Connection pool work?
Each JDBC resource specifies a connection pool. The JDBC driver translates the application’s JDBC calls into the protocol of the database server. When it is finished accessing the database, the application closes the connection. The application server returns the connection to the connection pool.
What is pool size in connection string?
A connection pool is created for each unique connection string. When a pool is created, multiple connection objects are created and added to the pool so that the minimum pool size requirement is satisfied. Connections are added to the pool as needed, up to the maximum pool size specified (100 is the default).
What is max pool size?
Max Pool Size: The maximum number of connections allowed in the pool. Min Pool Size: The minimum number of connections allowed in the pool. The default value is zero. Enlist: Signals whether the pooler automatically enlists the connection in the creation thread’s current transaction context. The default value is true.
How do I increase connection pool size in IIS?
IIS 8.5:
- Open IIS Manager.
- Expand the local server and click Application Pools.
- Find the application pool you wish to limit and right click on it.
- Click Advanced Settings.
- Under the CPU section, set “Limit” to the amount of CPU you wish to be the maximum.
- Set Limit Action to Throttle.
- Click OK to apply.
Does IIS have a timeout?
Time-out values allow the server to specify how long server resources are allocated to specific tasks or clients. Time-out settings are configurable from IIS Manager as well. For more information about setting the various time-out values, see Setting Connection Timeouts in the Help that comes with IIS Manager.
What is ODBC connection pooling?
ODBC connection pooling is a method of sharing active database connections with similar or identical connection characteristics. ODBC connection pooling can improve performance significantly because an ODBC application can take a long time to connect relative to the time it takes to process data.
What is connection pool timeout?
Connection timeout Specifies the interval, in seconds, after which a connection request times out and a ConnectionWaitTimeoutException is thrown. This value indicates the number of seconds that a connection request waits when there are no connections available in the free pool and no new connections can be created.
How connection pooling is used?
In software engineering, a connection pool is a cache of database connections maintained so that the connections can be reused when future requests to the database are required. Connection pools are used to enhance the performance of executing commands on a database.
Is connection pooling possible with rest?
Statelessness in a REST implementation requires that any state necessary to process a request needs to be included in it. It does not prevent the server to maintain a state anyway for efficiency. A connection pool is ok, so is an authentication cache on the server.
What is the connection pooling timeout?
A connection timeout is a contract between application and the pool; your application should get a connection within the specified time or get an exception. In the end, HikariCP throws connection not available if it times out.
