Well I don't agree completely. Statspack has its own place and 10046 = trace has its own. Statspack is supposed to give you a SNAPSHOT (or = should we call it materialized view now ...?) of the system for a given = time duration. Granted it is an overall picture but it will identify = issues SYSTEMWIDE. It helps you concentrate in possible problem areas.

The 10046 trace OTOH is process (session) specific. It will allow you to = identify issues within that specific process that you are tracing.=20

Statspack =3D> MACRO Level =3D> System Level 10046 =3D> Micro Level =3D> session level

My 0.15 cents.

I'm a relatively new DBA but I have 30 years electronic engineering =3D experience. I'm used to tools that work and actually measure what they =

purport to. I got all excited about the capacity planner about 6 months =
=3D

ago and asked the same questions you are asking now. Mostly, nobody is =
=3D

using it. It becomes a headache itself, the agent fails and causes you =
=3D

grief. I don't think you'll find much usefulness in it. When you start =
=3D

troubleshooting it won't give you anything helpful.=3D20

After reading Carey Milsaps Optimizing Oracle Performance I am less than =
=3D

thrilled with statspack also. You can't solve (or even determine) a =3D particular problems origin while looking at aggregate values.

The main value of these things is to provide a comfort level and =3D distraction to management. Attach your statspack report to an email and =
=3D

send it to your boss. It should keep him (or her) busy for some time =
=3D

while you work on the database.
