The first line gives you the total figures.
Processes named oracledbcih use 231682 * 4k of real memory, and 27314 *
4k of Paging.
If you want to be exact (strict) determining the memory overload due to
these processes on your system, you can substract the system segment
from these total figures because it is shared by every process and this
system segment is loaded at boot time.
In Feb 2002, I posted a question to this list to know how to interpret
the "virtual" figure in svmon reports, but I got no answer. Anyone knows
now ?
