DML operation against synonym oracle I have been reading the GoldenGate 11g R2 installation guide and it states:

Non-supported objects and operations in Oracle DML:
[...]
Synonyms
[...]

But I see in the next section that DDL operations are supported, so CREATE, ALTER, etc...
So, what is exactly a DML operation against a synonym and how is it not supported?
From reading the documentation, it looks like DML on a synonym for a normal object will not be replicated. For example, you have a table called FOO &amp; a synonym called BAR that points to FOO. An INSERT into FOO will succeed, but an INSERT into BAR will not, as it is a synonym for another table &amp; not a real base table. 

Test this in your dev environment to verify.
