We are using JBoss 4.0.4 with Oracle 10g. We are using ojdbc14.jar as the
driver.
I have a session bean for which transaction attribute is
<trans-attribute>NotSupported</trans-attribute>
When this session bean calls a stored procedure, if the stored procedure takes
a long time, i.e more than an hour, we get an exception -
java.sql.SQLException: Io exception : Connection reset
We narrowed it down and found that exception happens at exactly 60 minutes.
Yes, no one should expect to run a stored procedure which takes more one hour
and I have asked developers to fix it. However I want to find out why it
happened. If we wrap the stored procedure call in a session bean method with
"RequiresNew", this seems to work.
Is there any parameter which controls this timeout? The Transaction-timeout in
jboss-service.xml is set to high number (180 minutes) so there must be some
other parameter.
What am I missing? (oracle-ds.xml is attached).
