do I do when I see the error "Terminating the instance due
to error 474" in my alert log?
Answer: This is a serious error and you should
immediately open a service request with Oracle 's MOSC.
This can happen when the PMON process aborts:
PMON (ospid: nnnn): terminating
the instance due to error 474
Instance terminated by
PMON, pid = nnnn
ORA-474 : opidrv aborting process S000 ospid (nnnn_nnnn)
For a related issue, see MOSC for bug: 8310931 which is
fixed in 11.2.
