RE: Pinning/keeping plans in shared pool

I removed all histograms on all 26 tables of the query, but the optimization time (parse/execute phase depending on bind variable peeking) still takes 14 seconds.

Regards,
Brandon

Yes, there are certainly histograms involved here since I'm running the gather_stats_job, so I think I will take your advice and try removing all the histograms (by running gather_table_stats with method_opt=>'FOR ALL COLUMNS SIZE 1') and see if that makes a significant difference in the parse time.

So, you're at 10.2.0.2 on AIX 5.3 from 8.0.6. You have a couple of queries joining 20+ tables which performs OK on 806 and has a very long parse time with 10gR2.
