Why would you? The Optimizer takes things into account like the load on the system (in 10g). The load in your read-only system will differ from your production system, so that can lead to different execution plans. And unless you guarantee that every other configuration item is identical in the two systems, tuning a query on your read-only database may not yield the same results on your production database.

Sorry but no. The PLAN_TABLE is a permanent segment and you can only have temporary segments in the TEMP tablespace.
