Hi
Could some one please shred me some light on the following TKPROF's
output.
My questions:
1) Why a user SQL statements are shown as part of the recursive call
section, in stead of the non-recursive call section.
2) Why some SQL statements did not have a "wait event" section.
Eventhough a response times of that statement is very expensive.
3) Why a "FORALL" statement is too expensive.

Your sql-statement is INSIDE a pl/sql-statement. Whence it's recursive depth is 1.
327000 rows in 1 forall update might be on the large side, causing a lot of overhead.
Next time, please, please use code-tags for better readability.
