Home -> Community -> Mailing Lists -> Oracle-L -> RE: Top on Sun Solaris - More Shared Memory Discussing
On Solaris7 when I do "pmap -x pid" on an Oracle process. Notice from the
output below
Address 80000000 is listed under the Private portion not the shared portion
although under
the Permissions columns it says "shared". Now we all know that this is
definitely shared so why does Solaris report it under private? Is there a
reason behind this or just pmap reported it wrong?

You don't need to worry... the 190M includes the shared memory of the SGA for all processes that are connected to the database. Your TRUE process memory is much smaller
