Terminating the instance due to error 474 tips

Oracle Database Tips by Donald BurlesonDecember 14, 2015

Question:  What 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.
