Hello folks,

Not sure whether this is typical scenario but still :

You are a DBA. An huge commercial application is running against a reasonably big ORACLE database. Size close to a TB with 4 instances. On HP-UX ad XP arrays.

You DO NOT have access to the application. It is a third party application.

Issue is : things are running pretty slow.
Task is : Improve them.

The DBAs feel that the database is doing fine, the application is THE problem. The application guys feel exactly the other way.

Now, can somebody give me an idea about what can I do to prove that database is doing fine ? There are no bottlenecks ? There are no performance issues from database side ?

A list of such things is the thing I expect...
