Have you considered trying StorageXpert from Quest? - Kirti
-----Original Message----- Sent: Tuesday, July 23, 2002 10:58 AM To: Multiple recipients of list ORACLE-L All, We are tuning a new vital process on our data warehouse, and it is IO intensive - lots of parallel direct reads and writes. During our testing we are driving IO wait to ~60% (per top). questions: 1) is top a valid measure of IO wait? 2) Is a high io wait an issue to be concerned about? 3) how else can it be accurately measured? 4) How can I link IO wait to what is happening inside the database?
