Subject Re: DB Connection TimeOut
Date Mon, 06 Dec 2004 06:27:01 GMT
I think you got a same problem as me. Here is the method somebody told me.
One simple approach is to set the "validationQuery" property to an SQL
statement that does a simple select or something.  If this is set,
DBCP will ensure that this query works successfully before handing you
back the connection.  If the database has timed out the connection
while it was sitting in the pool, the query will fail, and DBCP will
close this connection and go grab another one (creating a new one if
needed). To make sure you set TestOnBorrow to be true at least.
 Good luck.
