Re: ORA-12838 please : Is possible to append two times to the same

I believe Oracle is enforcing this to guarantee consistency of the
database. I realise you are probably using the APPEND hint for performance
reasons but is it really necessary?

Otherwise you could perhaps look at move complex arrangements involving
temporary tables for the two inserts and then a single insert into the
final table. Perhaps even place the first query into a temporary table and
then for the second query add "union all select * from temp_table" to the
end to combine the two results. Some times you have to work with what you
are given - I doubt it's an Oracle bug, there's probably a real
complication with performing two appended inserts on a table without
commiting the first lot of data (perhaps a sudden inability to rollback the
transaction).

Hi Mladlen the idea is this, maybe there is a hidden parameter, or some
workaround to this.
I read in a previous post in this forum this seems to be a bug.

And I can't do a commit between them. >:)
