A sort extent pool latch? That's weird. You can get the sid of the guy holding the latch by joining v$latch.addr (or v$latchchildren if it's a latch with children - sort extent is not) against v$latchholder.laddr.
something like select sid from v$latch l, v$latchholder lh where l.addr = lh.laddr and l.name = 'sort extent pool'; On Saturday, December 8, 2001, at 06:20 PM, Doug C wrote: > Ok.. it's a sort segment latch.. any way to find out why?
