Re: Database link usage per object?

Hi,
in my opinion, there is no direct method but we could possibly do one by
instrumenting some code. You could store the value for "bytes received/sent
via SQL*Net from/to dblink" from v$SESSTAT and the access the object and
then check the value again?. I have not tried this myself but should work.
do let me know if this works or otherwise

best regards
