Just had a fellow tell me that explain plan in completely unreliable in 9.2 and getting accurate results requires direct SGA access on executing SQL (he is working in a RAC environment). They are running Precise, a good product, but this sounds like something a sales person told him. I can only recall that occasionally the plan executed is not the plan you see in explain plan. Anyone know the truth of this issue?
