Chandra -
The question is better suited for an Oracle group.
However, I happen to know the solution - since I do it all here.
On your Oracle server, add the following line your sqlnet.ora file:
  SQLNET.EXPIRE_TIME= 10
Then restart your oracle databases.

Subject: Db connection issue due to firewall

Hello,

We use a db datasource for one of our applications.
The issue is that there is a firewall between tomcat server 5.5 & db
server
(ORACLE 9i), that cuts pool connections after 1 hour of  ideal time.


We've tried several configuration using :
validationQuery
testOnBorrow
testOnReturn
testWhileIdle
timeBetweenEvictionRunsMillis
numTestsPerEvictionRun
minEvictableIdleTimeMillis

But that does not solve the problem

Could you please give me some advices about the way I have to configure
this
to get it working ?

Best Regards,
Chandra
