Re: ORA-12838 please : Is possible to append two times to the
 same table before doing a commit

Tim Gorman


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

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...
