Subject: Database Connection reset on Oracle 10g AS using Oracle 11g
database
Larry,
I saw an answer for one of the thread
http://www.mail-archive.com/user-java@ibatis.apache.org/msg03522.html
I have something similar, How do I modify spring.xml file to use
BasicDataSource feature to ping the query?
I have J2EE application running on OC4J application server. Where the
database connection is dropping / resetting after some idle time. The idle
time varies from 20 mins to 90 mins. The persistence layer is created
using Spring and iBatis with Struts as controller.
I am not able to find that why the code / oracle database is trying to
close the connection before it makes new one.
Here is the exception log:
