Greetings, Oracle 8174 on HPUX 11 Multiple CPU Server using EMC Disks I see 100s of Av Rd(ms) for some of the Datafiles in our hourly Statspack reports. If we look at the sar -d reports for the same time, they look good (%busy , avwait, avserv) no way near what STATSPACK is saying. Am I missing some thing here. Please advice. --=20 Regards & Thanks BN -- //www.freelists.org/webpage/oracle-l
