Juan Carlos,
First, I have to ask why you are bothering with APPEND when you are only adding 5 rows at a time? The APPEND feature (a.k.a. direct-path) as well as parallel execution is intended for loading thousands or millions or billions of rows. I suggest that you simply remove the APPEND hint — a whole lot easier...

However, just in case the sample code you posted to the list isn't what is truly being used, and in fact the real code is inserting more than 5 rows, then how about combining the two select clauses with a UNION statement, so that the two statements become one statement?

The ROWNUM in the WHERE clauses presents a problem, but perhaps:

> insert /*+ APPEND */ into ctb.xxxdeftra
> <first-SELECT-statement>
> union
> <second-SELECT-statement>;
>
> commit;

...and so on, as needed. This way, you can append dozens of such SELECT statements together and still make them one transaction. But please make sure that you are using the APPEND feature correctly, to load lots and lots of data? Not just 10 rows...

Hope that one or the other of these suggestions help...
