RE: Rollback waiting on 'cache buffer chains' latch - SOLVED

No, the physical process was gone (killed with kill -9):

15:34:17 SQL> select b.spid from v$session a, v$process b where
a.paddr=b.addr and a.sid=664;

SPID
------------
9859284

15:34:26 SQL> ! ps -p 9859284
      PID    TTY  TIME CMD

<no processes returned>


The only problem evident at the OS level was that PMON was spinning away
gobbling up a whole CPU, so it appears that PMON got hung on the
rollback for some reason.  It occurs to me now that I should've checked
to see what the PMON process was waiting on, but for some reason I never
thought to check that yesterday - too late now.  Well maybe it will show
me in the hanganalyze dump . . .

 
Thanks,
Brandon

So, did this hung session still have a physical process left in OS?
