Hi david, of course there is something you can do !!!! First tell your sysadmin to stop being so negative !!! Transfererate is data/time, where time is the sum of three steps - seek: time to position the heat to the right location - latency: then r/w head has to wait for the correct sector - transfer: actual transfer of data First you have to do tests to find out where you loose the biggest percetage of time. If transfer is your biggest problem the solution is easy : place the files on the out side sectors of the discs ( outer sectors are up to 4 times faster that inner sectors ). pls refer to man pages of mkfs/lvm to see how you can set up partitions or luns on hp-ux. If seek is your problem than a reorganizing of the data into a more sequential way or setting up bufferpages (kernel parameter in hp-ux) might give you an advantage if the inodes are used frequently and therfore are stored in the bufferpages so no physical read takes place. But of course setting up bufferpages takes away memory so there is a trade off when working with oracle. more or less the same is true for latency. hmmm just said "same" ... google for same and you will find some interesting white papers (S.A.M.E = stripe and mirror everything) HTH alex david hill <david.hill@lech An: Multiple recipients of list ORACLE-L <[EMAIL PROTECTED]> ateau.ca> Kopie: Gesendet von: Thema: OT: HPUX SCSI Performance [EMAIL PROTECTED] 05.02.2003 17:38 Bitte antworten an ORACLE-L Hi Guys I'm hoping there is sysadmin in the list that can help me. We just received a brand new Itanium Server to play with It has 2 U320 disk not striped or mirrored or anything Doing test and monitoring them through glance, is giving me a transfer rate of about 15Megs a sec These should be up around 60 - 80 megs right? My sysadmin says there is nothing he can do. Can someone tell if there is some sort setting he hasn't set or a config somewhere? Thanks.
