Write some tests in PL/SQL, changing the optimizer_mode as you go,
all while a 10046 trace is running.
The trace file will show which optimizer mode is used.

Subject: RE: Optimizer_Mode
Jared,
Ours is a hybrid application. We wanted to use First_Rows
during
oltp operation and all_rows during batch operations. I read somewhere
about this undocumented parameters, where with in pl/sql programs
optimizer_mode will be always All_rows. I just wanted to comfirm this,
also if this is true we may not have to write logon trigger or someother
mechanism to force All_rows. I am talking about 8i as well as 9i db.
Thanks and Regards,
Satheesh Babu.S
