  Hi all,
  My db is 9.2.0.4 on AIX os

 Query from view V$PGASTAT, we can determine RAM usage for Oracle instance. There is a column with name is Total PGA used for auto workareas. Some processes or application that will not counted in this statistics. I know them are Java and PL/SQL and anyone can talk to me which processes or app will not counted ? And to know the amount of memory used by them (Java, PL/SQL, ..) I used formula:

  Total pga allocated (also know from this view) - Total PGA used for auto workareas

  Am I right ? And to know which sessions consumes how PGA memory, plz show me methods to do this ?

Howdy, Stranger!
