Hi,

I'm back again with the problem :)

Firstly, I add the validationQuery and it works and I can see it in postgres 
logs.

But still not able to login after a while of inactivity....

Now, after 15 min of waiting, I'm getting a socket connexion timeout, but seems 
logic after such a long period of trying to connect.

Thank you again for your ideas and haven't found a solution.
You might try to enable keepalive on your postgresql connection. Connection porperties can be specified with the attribute "connectionProperties" (at least according to http://commons.apache.org/proper/commons-dbcp/configuration.html) or in the jdbc url jdbc://...?tcpKeepAlive=true. You can even specify the timeout for connnecting to your database.

Regards
 Felix

Regards, Luc.

Hi,

Thanks for the reply, I tried to add the options you told me about 
(testWhileIdle, timeBetweenEvictionRunsMillis, and maxConnLifetimeMillis), but 
I'm still unable to log after un hour ...
Do you have validationQuery configured?  testOnBorrow, testWhileIdle
do not work without it.


Best regards,
Konstantin Kolinko
