RE: performance question ablout oracle on F840 filer
by Lenzer, Mike 04 Apr '01

Bryan, What "tunings" did you apply to NFS, Filer, etc. ? Check below for some recommended values. Simply comparing filer ops is not a good measure of performance. For example: setting nfs mount options in /etc/vfstab to hard, intr, suid, rsize=32738, wsize=32768, proto=udp, vers=3 (which is a known good configuration), will result in "lower" nfs ops than say using r/wsize=8192, but your thruput will be the same or better. If I read you specs right, you're using 1xFC9 shelf for 2 volumes ? Assuming you are using the recommended spare disk, you max. number of spindles for say vol0 would be 4. The WAFL filesystem improves in performance with increasing number of spindles. Try moving the index's over to vol0, delete vol1 and expand vol0 by 2 or more disks. In a small volume environment, performance will be enhanced by placing just the online redo logs onto your local drive. Once you have more spindles you can place them on a seperate volume on the filer and mount them over your 2nd GbE link. It is ideal to seperate sequential writes (such as redo logs) from random i/o over a separate GbE link and separate volume. To ensure your problem isn't the GbE connection, try testing for raw thruput of data by issuing a "dd if=/dev/zero of=/toaster/test bs=32k" command. Then umount and remount the filer mount point (to avoid local caching) and read it back. If the numbers are low, you may have a duplex-mismatch and need to ensure auto-negotiation is enabled for the NICs in the E3500. Needless to say, ensure Solaris 2.7 has the latest patches applied and the F840 is using at least Data ONTAP 6.0.1R3 or better Data ONTAP 6.1 which is at FCS on http://now.netapp.com <http://now.netapp.com> Also consult the Technical Reports below for further information: http://www.netapp.com/tech_library/3047.html <http://www.netapp.com/tech_library/3047.html> http://www.netapp.com/tech_library/3105.html <http://www.netapp.com/tech_library/3105.html> /M/ Michael Lenzer Oracle TME Network Appliance Inc. 495 East Java Dr Sunnyvale, CA 94089 USA -----Original Message----- From: brynay_cradle [mailto:bryany@cradle.com.tw] Sent: Tuesday, April 03, 2001 11:30 PM To: toasters Subject: performance question ablout oracle on F840 filer Hi , My customer setup oracle 8.15 on sun E3500 (Solaris.7) and put oracle database on filer F840 , but performance is poor.

oplock problems
by Matt Graham 04 Apr '01

04 Apr '01

Hello, I have been having oplock break time outs, and I can't seem to isolate the cause of the problem. It is only certain clients that are experiencing the problem. One of the clients seemed to be fixed when I moved it from the switch that it was on to a hub (which doesn't make any sense, and may be coincidental) Also, I never noticed these problems before we converted to a fully switched network The clients are win98 and nt4. I am running NetApp Release 5.3.6R2. I am now running with oplocks disabled, but it seems like a poor solution to me. Any help appreciated, Matt

It works fine here - all you need is to have the remote shell daemon (rshd) running on the Sun box, with the NetApp filer allowed to run commands as root ("netapp.network root" in root's .rhosts file). Alternatively, you could do something like: rsh netapp dump 0u / > /dev/rmt/0 - the output of the netapp's 'dump' command will be sent to standard output, which goes to the tape drive.

Inodes a go go
by Tom "Mad Dog" Yergeau 03 Apr '01

03 Apr '01

Okay, so the maximum number of inodes is 95% of the true (not usable) size of a volume divided by four. And if you're daring enough to type this into your filer, it will tell you that anyway: usvasvfile-001> maxfiles inquisition 50000000000000000 Max inode count cannot exceed 201249946 Now here's the problem. I just passed this information on to the developers who wrote the program that uses up this exceedingly ridiculous number of inodes, and they tell me that they are going to start using them up even faster than in the past, and we may run out within six months, and is there anything we can do to get more inodes? I suggested they re-write their program to not generate tens of thousands of directories every day, but I don't know how well that will fly. Can anyone think of a way to get more inodes? NetApp folks, any hope a RFE for a higher inode limit would go through? Thanks, Tom As our developer says: -----Original Message----- From: Joseph Manak Sent: Tuesday, April 03, 2001 1:56 PM To: Tom "Mad Dog" Yergeau Subject: RE: We will endeavor to pursue an inode conservation program....

Hi Kunihiko, The dump utility on a NetApp filer can only move data to a tape drive which is directly attached to a filer. It can not move data to a tape drive which is attached to a Sun server. If you wish to leave the tape drive attached to your Sun 450, you will need to buy a software package which can control that. Some of the backup packages which will allow you to move data from the filer, to the tape drive attached to the Sun are : WorkStation Solutions- Quick Restore v2.7; Syncsort - Backup Express v2.1.3; Bakbone - Netvault 6.03; Legato- Networker 6.0.1 with SnapImage v1.5.

RE: Filer Serial Connectivity
by Mike Sphar 03 Apr '01

03 Apr '01

Actually, is there any reason you *couldn't* hook a modem up to the console port? I used to hook modems up to the console ports of old UNIX systems all the time in my early days of tech support. The console port is just a serial port, and the modem is just a serial interface device. I don't see why you couldn't hook a modem up to a console port and as long as you got the cabling right and configured the modem right it should work. Though personally if I were going to go through this sort of work I would likely hook the modem up to a separate terminal server or a machine running conserver. -- Mike Sphar - Sr Systems Administrator - Engineering Support Services - Remedy Corporation BOFH, GWP, MCP, MCP+I, MCSE, BFD -----Original Message----- From: Paul Brosseau [mailto:paulb@netapp.com] Sent: Tuesday, April 03, 2001 6:42 AM To: geen(a)ti.com; toasters(a)mathworks.com Subject: RE: Filer Serial Connectivity As for the dial-in thing, That is the old way of doing things. Today you want to leverage your network to do things. I think that filers should have an option to hook a modem directly up to the console port, but the usefulness of such a feature is pretty limited. The product design is network centric. In the old days the network used to be unreliable. Today's switched netwoorks are probably the mostreliable part of the computing infrastructure. Except of course for your filers ;-)

One thing we do here locally is we purchased IP addressable power strips. Most of the major power guys sell them these days and that allows us to power cycle and filer head, shelf, switch, whatever regardless of whether the box head, shelf, etc. has the capability. I'll feed back this feedback into the remote supportability group. I'm sure they are already thinking about it, but it never hurts. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com
