Fields

Connection Pool The name used to identify the Connection Pool.

URL The URL of the database to use.
Username The user id.
Password The password.

The password must be entered twice and both passwords must match.

Initial Size The number of connections to start off with when the server is started.

10 is the default for iServer.

Initial Size must be a value greater than 1.

Maximum Size The maximum number of connections to allow.

20 is the default for iServer.

The value must be equal to or greater than the value for Initial Size.

Timeout The maximum number of minutes that an inactive connection will remain open in the connection pool before it is closed.

30 minutes is the default for iServer.

-1 is used to always keep the connection open in the pool while the server is running.

The number must be at least 1.

Setting this value too large or to -1 may result in database connection timeouts and setting this value to small may impact performance and memory requirements.

This parameter is ignored when Connection Pool Interval in Server, connection_pool_interval in iws.ini, is set to -1.

Parameters Any parameter used by the JDBC driver during the creation of the Connection Pool.

Zero or more parameters can be specified by entering line delimited key=value pairs.
