concurrent manager are not going to down nomally
Hi experts,
maximum of time when i have take down my application some of concurrent managers is not going to down it is stuck even after a long time wait (30min - 1hr). at last i have kill that stuck manager manually by using kill -9.. i have check in background to find out any running process ( select * from fnd_concurrent_process where phase_code='R') but no any running request find out. i can not understand why the managers are not going to down?
plz suggest how can i find out the managers stuck region. and take down the managers normally.
