    allocated shared memory to a process


      Our db running in 24*7.Every quarter only we bounce the database.
      Some of our db sessions are always active.

      How to find how many shared segments allocated to a particular process(at OS level) like pmon or end user sessions in it's life?

      Is it possible to find when that session has maximum segment size allocated and minimum segment size alloacted in it's life.

      Normally OS people use topas command.But i don't have much knowledge on unix.

      Thanks & Regards,
