Listers, We have a new 11g based hybrid application that a third party vendor is configuring. We observe some slowness in the response times. I do not see any slow sql in v$sql. The vendor is recommending that we set the OPTIMIZER_MODE to FIRST_ROWS to get better response times, among other parameter changes. I have read in few sources that FIRST_ROWS is not generally used, with oracle itself using ALL_ROWS. Can anyone advise? -- Thanks, Ram.
