Hi forum,
i have RP2450 9000/800/SD16000 with 16Gb Ram
hp-ux 11.11 Oracle 9.2.0+BaaN application.

when i moni system via glance the Disk Utilization seems %100 and responsible deamon

Who could check or tell me what is wrong on my
kernel param?or give any link about what i have to change on my kernel params?is there any recomendations about my system spec and kernel?Which kernel params of my system might be wrong or missing?

Please urgent help!!!

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Hi,

Is this a new application or has this application behaviour just changed ?

which exact version do you run ?
select * from v$version ?
(have you applied oracle patches for oracle 9.2)

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Only thing I see is shmmax - mine is set to:

shmmax 0x400000000


But you say it's disk utilization - what is on theat disk?

Is it a particular lvol? IE- - do you have redo logs on same disk as indexes?

Some guidelines I follow:

APPENDIX D - Oracle Requirements

Vgcreate volume groups as per the following standard (these are minimum)

Preamble: VG00 - VG09 are internal disks, VG10 and higher are reserved for EMC.

VG00
The root volume group VG00 should be mirrored and only contain OS files.
Primary swap should be 1 x memory
/ - 140MB (HP Default) set higher - 200 MB
/usr - 2GB
/usr/openv - 512MB
/var - 4GB
/tmp - 512MB
/stand - 256MB
/opt - 2GB
/home - 512MB with quotas (32MB soft, 64MB hard)
/var/opt/perf/datafiles - 2GB
If adding CCMON - then /opt/cctool - 256MB
Note: /var/tmp should be a symbolic link to /tmp. /tmp should be 1777 (sticky bit).

VG01
/app - 512MB
/usr/local - 512MB
/app/admin - 512MB
/var/adm/crash - 1 x memory + 512MB
VG02
File system swap
VG03
Applications
VG04-VG09
Reserved

VG10 - VG19
Log volumes (redo, archive, etc)

VG20 - VG256
Data volumes

Miscellaneous

Don't use strict/contiguous when creating logical volumes.
Create file systems with "large file" support (fsadm).
Mount file systems with "delaylog".
Oracle
The following is the typical oracle layout:

Volume Size File System

vg01 4 Gig - /app/oracle
vg01 500 Meg - /app/dbcorp
vg30 6 Gig - /data/oracle/irsp/data01
vg30 6 Gig - /data/oracle/irsp/data02
vg30 6 Gig - /data/oracle/irsp/data03
...
Can all be on one mount point if need be, but this probably will reduce performance.

vg31 2 Gig - /data/oracle/irsp/indx01

vg31 2 Gig - /data/oracle/irsp/indx02

vg31 2 Gig - /data/oracle/irsp/indx03

...

Again, can all be on one mount point if need be, but this probably will reduce performance.

vg12 12 Gig - /data/oracle/irsp/arch
Should be on a different mount point than dataXX and indxXX as this will benefit from different mount flags.

vg10 8 Gig - /data/oracle/irsp/exports
Also should be on a different mount point than dataXX and indxXX as this will benefit from different mount flags.

vg10 1.5 Gig - /data/oracle/irsp/redo01a
vg11 1.5 Gig - /data/oracle/irsp/redo01b
redo01a & redo01b on different physical volumes

vg10 1.5 Gig - /data/oracle/irsp/redo02a
vg11 1.5 Gig - /data/oracle/irsp/redo02b
redo02a & redo02b on different physical volumes

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Hi,

Kernel parameters have little to do with the disk utilization.

Post your 'sar -d 5 5' 'sar -b 5 5' 'sar 5 5' outputs. Also post the following details.

1. How big are your LUNs.
2. How many VGs you have and with how many disks.
3. How big are your LVs.
4. What's your storage system.

-Sri

I'd collect some performance data with the past recommendations, or get more comprehensive with the script I'm attaching.

This is a comprehensive link on performance tuning:

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Better thing would be to post here your initbaan01.ora file or spfilebaan01.ora rather than your kernel params.

One more thing : How many CPUs are there on this box ? Are you using Raw devices ? Asynch-ios ?

Fred

as you seem to look for perfs :

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Your kernel params are absolutely fine.

Be aware that if you're using your default Measureware/Glance configuration - that 100% disk utilization in Glance SHOULD NOT BE TOTALLY BE BELIEVED in.. The default glance/mwa config will give glance users a 100% DIsk utilisation graph/stat even if just one LUN is reaching 90-100% Utilisation.

Your best gauges to tell you if you've an I/O (a serious one at that are):

1. sar -d (you've queue lenghts gt 0, gt. 20 access/service times

2. sar (CPU states where %WIO is consistently high -- say close to 50%)

3. vmstat (you've many blocked processes)

4. Oracle complains that the system is really waiting in I/O states.

What storage do you have? an EVA perhaps?

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Some points about Oracle :
. Is time_statistics=true necessary ? It implies a processing overhead.
. If you have more than 1 CPU, I would go for db_writer_processes setting.
. How often do you switch log ? (You can see it in alert.log file)

Regards,

Fred

Re: hp-ux 11.11 kernel param+Oracle 9.2.0 performance+General performance

Also,
could you run a statspack report when the system is hit (and another one when the system is fine would add essential info)

Performance from oracle prospective is essential, the OS stats aren't enough !
