We are using JBOSS version 4.0.5GA and Oracle 10g version 10.2.0.4. During the day the database process in the OS increases. In the application all open connections are closed appropriately. The connection string are written in the JSP pages and java processes. Does JBOSS control or close open connections ? Or is it possible that Jboss is unable to close the database connection/session. As the open connection increases and the Databse and the system becomes slow, forcing us to restart the DB.
