Will "sys" Component of CPU Utilization be Higher on a RAID 5 Volume Versus a RAID 1+0/0+1 Volume on a Database Server ?
Under peak Hybrid Loads the CPU Utilization's "sys" component is 50 % & "usr" component is 50 % . Our Hybrid Application DATABASE is setup on a Hitachi Storage Box configured such that a SINGLE RAID 5 Volume spans across ALL the underlying Disks of the Storage Box . Qs. Could Hardware RAID 5 be the Cause of High "sys" on respective DB Server ? Qs. Any people having any experience of HIGH "sys" on SF15K machines with Hybrid Databases ? NOTE Application Software sits on a Different APP Server machine . Banking Application Database Oracle 8.1.7 Solaris 8 VXFS SF15K DB Server - 40 CPUs Hitachi Storage Box from HP Concurrent Oracle sessions = 5000 Will provide any info needed Thanks -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: VIVEK_SHARMA INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
