16 Managing JDBC Connectivity
16-36 Administration Guide
If you enable the connection pool to grow as demand for connections increases, new
connections will cache statements as the statements are used. The startup class cannot
load the prepared statement cache for new connections. If you enable the connection
pool to shrink, the connection pool will close connections after the shrink period has
been met and connections are available. There is now way to specify which
connections to close first. Therefore, the connections for which you loaded the
prepared statement cache may close before non-loaded connections close.
