http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10249 Tomcat hangs with Interclient JDBC driver [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|INVALID | ------- Additional Comments From [EMAIL PROTECTED] 2003-04-02 10:29 ------- I had the same bug with Oracle DB. It's very unlikely that this driver hangs. The problem is caused in the "endless" loop at org.apache.commons.pool.impl.GenericObjectPool.borrowObject(). After creating the new connection, some check is done: if(_testOnBorrow && !_factory.validateObject(pair.value)) { In my configuration the ValidationQuery parameter was generated by the manager but i left it empty. This caused validateObject() to return false, which then caused the endless loop. I would expect an Error or any appropriate handling in this case since it is a fatal misconfiguration. Workaround: Remove the parameter for the validation query from the config in server.xml --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
