Can you clarify a bit more on #2? Is DDL something that would be common or

well tom is almost 99% there ... there is the rest of the story ... about
GTTs that
1. you better use dynamic_sampling with them
2. any even one session is useing it, you can't perform most DDLs 3. forget
doing truncates on them, KGopal probably has the proof.
otherweise they work almost as advertised ...
