Oracle using NetApp
by Robin Winslett 20 Aug '02

20 Aug '02

Has anyone got experience with running Oracle on NetApp filers? I am looking for information for a project I am involved in. 1. How does performance really stack up compared with a DAS or SAN solution? Does the IP stack -vs- SCSI stack cause a significant performance lag? 2. Are there compelling reasons why this would be a preferred solution? 3. Are there compelling reasons why this solution should be avoided? 4. What are the gotchas of such a solution? Are there configuration issues that can trip you up? I've read the whitepapers on the NetApp and Oracle sites. I am looking for someone though that has actually done this. Thanks, Robin winslett(a)ev1.net

Well my goal is to run a differential on the active file system monday through friday. Then on Monday morning at 12:05 am do a full on weekly.0. Then I need to reset the archive bits on the active file system so that the differential Monday night will backup the proper data. -----Original Message----- From: Benn, Paul [mailto:paul.benn@netapp.com] Sent: Tuesday, August 20, 2002 12:02 PM To: Steve Evans Subject: RE: Reset Archive Bits don't know specifically what you're trying to achieve but perhaps you could create a script to run on the Windows machine once a week that might do what you want. you'd need to leverage rsh and manually create and delete the weekly snapshot. something like: REM delete the snapshot created the week before rsh [filer's host name] [-l username] snap delete [snapshot name] REM reset the archive bits attrib -a /s REM create a snapshot that you want to backup from rsh [filer's host name] [-l username] snap create [snapshot name] REM run the backup ntbackup [options] -----Original Message----- From: Steve Evans [mailto:sevans@foundation.sdsu.edu] Sent: Tuesday, August 20, 2002 11:48 AM To: Benn, Paul Subject: RE: Reset Archive Bits Not if I backup the snapshot though right?

by the way, a "full" backup (assuming you do that once a week) should clear the archive bit as well. regards, Paul Benn Network Appliance -----Original Message----- From: Steve Evans [mailto:sevans@foundation.sdsu.edu] Sent: Tuesday, August 20, 2002 10:13 AM To: toasters(a)mathworks.com Subject: Reset Archive Bits I'm looking at running differentials during the week and then backing up weekly.0 Monday morning at 12:05.

secure filer access
by Moritz Willers 20 Aug '02

20 Aug '02

I'm trying to configure ssh/https admin access from any host to a filer, but no telnet, no http admin and rsh access from one host only (the admin host). I can't find how I can control ssh/https access separately. Is this really not possible or am I missing something? how do others manage secure filer management via cli and gui? thanks - Moritz Visit our website at http://www.ubswarburg.com This message contains confidential information and is intended only for the individual named.

how about the "attrib -a /s" command? -a = clear the archive bit and /s = subdirectories -----Original Message----- From: Steve Evans [mailto:sevans@foundation.sdsu.edu] Sent: Tuesday, August 20, 2002 10:13 AM To: toasters(a)mathworks.com Subject: Reset Archive Bits I'm looking at running differentials during the week and then backing up weekly.0 Monday morning at 12:05.

RE: Exchange 2000 Cluster
by Benn, Paul 20 Aug '02

Hello Greg, I assume that you will be using SnapManager for Exchange, which is the only way we support the use of Exchange on filers. If so, the installation procedure for MSCS can be found in the SnapManager for Exchange 2000 System Administrator's Guide. You can download the guide in PDF format from the NOW site (now.netapp.com). You may also need to apply the Microsoft hot fix for Q307939. This will be called out in the guide as well. Please let us know if you have any further questions, Paul Benn Network Appliance -----Original Message----- From: Greg Veach [mailto:gvj@veach.net] Sent: Tuesday, August 20, 2002 7:48 AM To: toasters(a)mathworks.com Subject: Exchange 2000 Cluster I am looking for documentation (configuration, limitations ...) on using a filer in an exchange 2000 cluster.

Re: Oracle using NetApp
by Joseph Bishop 20 Aug '02

Hello, We have 6 servers hitting our NetApp 760 with about 25 instances. Love love love the filer. I have not seen a problem with the database even if the network goes down for some time (20 minutes and more). The only hiccup I have seen is if the filer is rebooted while databases are operating. A control file that is located on the filer may have a lock held against it when it comes back up. We run 1 filer and 2 local control files. If that happens, delete the filer based control file and replace it with a copy from the local set. Then your database will restart. Cheers, Joe At 09:35 AM 8/20/02 -0400, Brian Long wrote: > > 1.
