Tanel,
Thanks for replay,

Your suggestion can be the way to get the right information.
I am aware about x$ksmup & x$ksmpp unfortunately this is third party
application and we cant use those views.
The dumping can be the strategy.
.
I have found ?Diagnosing and Resolving ORA-4030 errors? (Note 233869.1).
There is reference to the EVENT: 10261. It is seems that this event can be
useful for the purpose that we are discussing.
.
Are you aware, dose heapdump and 10261 works well in MTS env.?
.
