We are using JBOSS as our application server and it has a pool of connections for the clients. if a client do an update on a table through the application server in the database and if the client kills its connection by typing control c then it should rollback the transaction but that application server force it to be commited which should be rollback.
so is there anyway to change the behaviour of the oracle to rollback when the any client kills its session instead of exit it.
