TKPROF Report - Do not understand report

1. Could someone help me make sense of the report. I am not clear on what to make sense of when the:

Parse and Execute = 33
but the Misses in library cache during parse = 0.

call count cpu elapsed disk query current rows
------- ---- --- ------ ----- ----- ------- ----
Parse 33 0.00 0.00 0 0 0 0
Execute 33 0.00 0.05 0 66 331 33
Fetch 0 0.00 0.00 0 0 0 0
------- ---- ---- ---- ---- ---- ----- ----
total 66 0.00 0.05 0 66 331 33

Misses in library cache during parse: 0
Optimizer goal: CHOOSE
Parsing user id: 21

2. Also I have put an attachment, could anyone give me a breif on what can be inmproved from the tkprof report.

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..

This means that you parsed the query every time you executed. My guess is you are updating in a loop and explicitly parsing and executing in each iteration of the loop. Explicitly parsing every query will limit your scalability and overburdens your CPU.

What is the difference between "soft parse" and "hard parsing". How can soft parsing be avoided.
