Executing a DDL command without committing

Question

Hi!
I have a PLSQL procedure that uses EXECUTE IMMEDIATE CREATE OR REPLACE DIRECTORY 'FROM_DIR' AS 'path' to obtain access to directories on the server. Before and after the statement is run, I have a list of inserts and updates into tables.
When the statment is run, the database automatically issues a commit.
I want to avoid the commit. Does anyone have a suggestion to how I can accomplish this. Is it perhaps possible to run the DDL statement in a separate session, thus avoiding the commit in my main session?
