Pooling tab

The Pooling tab allows you to specify connection pooling data source settings. The fields are optional unless otherwise noted. On this tab, provide values for the options in the following table; then, click Apply.

See "Using DataDirect Connection Pooling" for a general description of connection pooling.

Connection Options: Pooling	Description
Connection Pooling	Specifies whether to use the driver’s connection pooling. If enabled, the driver uses connection pooling. If disabled, the driver does not use connection pooling. Default: Disabled
Connection Reset	Determines whether the state of connections that are removed from the connection pool for reuse by the application is reset to the initial configuration of the connection. If enabled, the state of connections removed from the connection pool for reuse by an application is reset to the initial configuration of the connection. Resetting the state can negatively impact performance because additional commands must be sent over the network to the server to reset the state of the connection. If disabled, the state of connections is not reset. Default: Disabled
Max Pool Size	The maximum number of connections allowed within a single connection pool. When the maximum number of connections is reached, no additional connections can be created in the connection pool. Default: 100
Min Pool Size	Specifies the minimum number of connections that are opened and placed in a connection pool, in addition to the active connection, when the pool is created. The connection pool retains this number of connections, even when some connections exceed their Load Balance Timeout value. Default: 0
LoadBalance Timeout	Specifies the number of seconds to keep inactive connections open in a connection pool. An inactive connection is a database session that is not associated with an ODBC connection handle, that is, a connection in the pool that is not in use by an application. Default: 0

If you finished configuring your driver, proceed to Step 6 in "Data source configuration through a GUI." Optionally, you can further configure your driver by clicking on the following tabs. The following sections provide details on the fields specific to each configuration tab:

• General tab allows you to configure options that are required for creating a data source.
• SQL Engine tab allows you to configure the SQL Engine's behavior.
• Advanced tab allows you to configure advanced behavior.
• Web Service tab allows you to configure web service behavior.
