Connection validationQuery mechanism should be replaced by new method
connection#isValid()
------------------------------------------------------------------------------------------
Key: DBCP-357
URL: https://issues.apache.org/jira/browse/DBCP-357
Project: Commons Dbcp
Issue Type: Improvement
Affects Versions: 1.4, 1.4.1
Reporter: Philippe Mouawad
Hello,
Current method of connection validation relies on validationQuery.
This method has a rather big performance impact on the DB (CPU, for example 3%
with SELECT 1 FROM DUAL even with Oracle 10G FAST DUAL) and make an additional
query for each borrow (when testOnBorrow is true).
Wouldn't it be better to use new JDBC 4 method isValid which relies on Driver
check ? (Oracle would for example use its internal method ping)
Thank you
Philippe
