Greetings Oracle 9i AIX 5L we are using SAN Stroage I see quite a few SQL in the STATSPACK report with high Elapsed time, I notice the following: 1. Disk is 100% bussy - topas report 2. sar -d report - Service time is less than 20 msec, disks show 99 to 100% busy 3. STATSPACK Report for file io shows 3 digit numbers for Av rd (ms) 4. STATSPACK Report TOP SQL Shows high Elapsed time. Some of the SQL are doing FTS What other stats should I look at to narrow down the issue Should I go behind Tuning the Queries or Storage, spreading datafiles across multiple disks. Apprecaite your thoughts -- Regards & Thanks BN
