Hello all,

I have failed in my attempts so far, but what I'm trying to do is trace a
session during a soft parse where I will see in the trace that the child
cursor was found in the library cache and there is no need for a hard
parse. It's part of a research interest of mine.

I'm still searching for blogs that have done this already, but have not
found one yet.
I've tried strace with no success
I'm also looking for trace events (like 10046) that will trace this info.

So far:
10053 won't show anything because the child cursor already has an execution
plan
10046 level 12 does not show what I'm looking for

Any help is greatly appreciated.
