High Disk IO

735688Jan 31 2010 — edited Feb 2 2010

friends!
Suddenly, we are facing very poor performance on our database. All our application jobs are taking almost double time to complete. I have observed 100% disk I/O on OS through "glance" command. I have compiled the STATSPACK report, which is showing normal workload on database. In back days, this problem was occure due to SAN device but SAN team is not inticating any problem on their site.

Quick response will highly appreciate.

regards
