SGA lock question

[George_Dodds]

OS: 11.23

DB: Oracle 9i

Below are our current sga settings, I just need to confirm something.

If lock_sga is set to FALSE even if dba MLOCK is set in privgroup, does that mean that the Oracle memory is not ring fenced, ie it's being shared with the OS, or is the memory thats allocated to Oracle dedicated with those settings.

lock_sga                             boolean
FALSE

:/etc # cat privgroup
dba MLOCK

Cheers

George
