Solaris

I have multiple oracle databases on one server. All the database are running from the same user i.e. oraent.
The process for each database can be distinguished by the ps -ef command

Eg :

Code:

ps -ef | grep oraent

The Output :

Code:

  oraent  5361     1   0 20:58:05 ?           0:00 oracledb1 (LOCAL=NO)
  oraent 11465     1   0 18:41:00 ?           0:03 oracledb2 (LOCAL=NO)
  oraent 27709     1   0 12:25:49 ?           0:01 oracledb3 (LOCAL=NO)

I need to find the total memory usage for each database at a given time.

I tried prstat, but there was no column which could differentiate the process per database.

Hope i was able to convey my requirement.

Any help will be welcome.
Thanks in advance..
