JdbcConnectionPool
public JdbcConnectionPool(JdbcConnectionFactory factory,
DefaultPoolController controller,
int min,
int max,
boolean autoCommit)
throws java.lang.Exception
setTimeout
public void setTimeout(long timeout)
- Set the timeout in milliseconds for blocking when waiting for a
new connection. It defaults to -1. Any number below 1 means that there
is no blocking, and the Pool fails hard. Any number above 0 means we
will wait for that length of time before failing.
