Hello All,

I Have a doubt :

I have a query which is executing over a db link.
Suppose my query is :

select * from dual@test_link;
On a Assumption that this query takes fairly heavy resources ,then which db's AWR will be showing the wait event : SQL*Net message from db link Doubt

Regards,
tigsav

Who says the remote DB even IS an Oracle DB AND IS configured to have AWR? YOur local oracle DB certainly can't depend on that.

Think a little bit.
Which db can wait for "SQL*Net message from db link" due to this query?

      give me the dual row 
db1 ------------------------> db2
         here's the row
    <------------------------

Who can wait for something from the db link?
