1. You are essentially "soft parsing"..since your Misses=0. You aren't hard parsing. So don't be overly concerned. If you don't know the difference see asktom, metalink, technet etc

2. Nice try. If you have a specific problem/issue, state the same. I'm not gonna pore over your tkprof output and recommend solutions! It's like someone posting a statspack report..and open endedly asking for suggestions! Yeah right..
