Question : Websphere J2EE application loses its connection to Oracle DB when the application is used in the morning

Our J2EE application running on Webshpere 6 is losing its connection to the Oracle 10 g database, every morning when users first use the application. The current fix is to restart the Web Sphere and then the application is ok to use again. It seems that when the application isn't used when the users go home until the morning, that Websphere loses its connection to Oracle.
We have confirmed with the DBA that the Oracle DB was not brought offline during the night.

In the WAS connection pool settings, is there a reconnect setting to the database
If there is such a setting then, where is it located?

Here are the current connection pooling settings

connectionTimeout="180"
maxConnections="64"
minConnections="2"
reapTime="300"
unusedTimeout="1800"
purgePolicy="EntirePool"

Hi,

Once the users have logged on does this occur? If so, how many users?

Also, i presume you are not using clusterware on the server and/or the application is not protected by this?
