SGA/PGA (Memory) in RAC environment.

598389Aug 27 2009 — edited Aug 28 2009
Guys,

I would like to get your inputs on SGA / PGA settings on a RAC database.. Does LMS/LMON/LMD process use memory which is part of PGA or these process allocate memory at OS level ?

I would like to see the usage of Memory used by a database.

below sql from Mr. Kyte's website i have used. Somehow i am not getting real usage of the system. Any help would be appreciated.

Thanks

select
ssst.sid,
stn.name ,
round(ssst.value/1024/1024,2) memory ,
USERNAME,
COMMAND,
OSUSER,
MACHINE,
TERMINAL,
PROGRAM ,
ssst.STATISTIC#
from v$statname stn,v$sesstat ssst , v$session ses
where stn.STATISTIC# = ssst.STATISTIC# and
ssst.sid = ses.sid and
name like 'session%pga%memory%'
order by 3 asc ;
