Searching hard parses

2001-06-15 Thread Fernando Papa


Hi everybody!

I have this numbers for parses:

1402684 parse count (hard)
9766294 parse count (total)

14,36   % of my parses are hard

My database it's up since more than two days, with 943249 cumulative logons
(oltp). The problem is two months ago the percentage of hard parses was
about 12%... I try to find which sql sentences are forcing hard parses,
but I don't know I can do it querying some v$ views or I need to examine
directly all the sessions...

Thanks in advance!

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...
