Dear friends

Recently i configured Oracle 8i on Win2000 with clustered nodes.AS a experiment i installed one application.To my surprise the application is running very slow.Matter of fact the same application is running on small server very well ,the database configuration is o. k. since this is the only application running.Even the network is seems to be o.k. Can u tell me what are the areas which i can check to improve its performance as shortly i have to move it into production.All your comments and remarks are appreciated.
regards
