Re: Searching hard parses

Hello,

First of all, let's notice that:

• number of .... means AMOUNT
• ratio means SPEED
• time means TIME

If you don't encounter time related events such as waits, CPU usages, It doesn't make sense What the values of AMOUNT and SPEED are.

In you case, startting from parse count is not correct way. You should focus on parsing if parse time is high.

use itrprof SQL Analyzer to see parse time, parse amount with their relavent SQLs.

regards...
