Internal disk configuration for oracle

Hi experts
I need some guidance for internal disk configuration for oracle
requirements are for 2 node clustered VM on linux OS OEL
the OS will be for RAC, OEM
will RAID 5 be optimal setting
this is not production env
thanks

RAID+10 provides better performance.

How to determine raw disks configured for OCR/voting disk, ASM spfile

I have a two-node Oracle 10gR2 RAC configuration using raw disks. Basically, raw disks are used for CRS's OCR/voting disks, ASM's ASM spfile and disk groups.
Is there a better way to figure out what raw disks are configured in Oracle using methods other than those shown below:
- To find out votedisk:
# crsctl query css votedisk
0. 0 /dev/ora_crs_vote1
1. 0 /dev/ora_crs_vote2
2. 0 /dev/ora_crs_vote3
- To find out OCR:
# ocrcheck
Status of Oracle Cluster Registry is as follows :
Version : 2
Total space (kbytes) : 525836
Used space (kbytes) : 3856
Available space (kbytes) : 521980
ID : 1603037329
Device/File Name : /dev/ora_ocr_file1
Device/File integrity check succeeded
Device/File Name : /dev/ora_ocr_file2
Device/File integrity check succeeded
Cluster registry integrity check succeeded
- Is there a way to figure out what disk device is used for ASM spfile?
- To find out raw disks configured for disk groups:
while connected to the ASM instance in sqlplus:
SQL> select name,path from v$asm_disk where name like 'DG%';

Optimum Disk Configuration for CS6

Hi Hardware forum members,
I have read the Generic Disk Guidelines, read the various forum threads on this topic, watched the Adobe Video2Brain videos and am still confused re optimum disk configuration for CS6 Premier Pro.
( lots of disagreemnet on HDD RAID0 versus SSD )
The video and advice from Adobe is to have a separate disk for each disk for each type of file so that you are not reading and writing from the same disk.
I rang Adobe technical support and they advised me that if I had 4 individual separate SSD's they would allocate one to the O/S and Programs, one to the Media and Media Cache which they said had to be on the same disk, one to the Project and finally one to the Export and Preview.
I then asked them if I purchased another SSD so that I had one for the O/S and Programs and then 2 x 2 in a RAID0 configuration, how would they allocate the the drives. They said they would allocate one RAID0 volume to the Media and Media Cache and to the second RAID0 volume they would allocate the Project, Export and Preview. Doesn't this contradict the advice to keep the files separate, as your Project files would be on the same disk as your Export and Preview ?
In any case, they said the 2 X 2 RAID0 configuration would give the better performance.
What do the forum members here think will be the better disk configuration from the two options above ?
What about TRIM support for SSD'S in a RAID0 configuration - is that still an issue, before I commit to the 2 X 2 SSD in RAID0 configuration.
FYI - Backup will be to 4 x 3tb Seagates in a RAID5 config and the SSD'S under consideration are the Samsung 840 Pro's.
Your thoughts and recommendations will be most welcome.
Kind Regards
Martin.

Hi Jim,
Thank you very much for taking the time to respond to my post - it is much appreciated.
I have ruled out the 2 x 2 ssd in raid 0 as an option due to the lack of TRIM support for this configuration as the performance would just deteriorate over time.
Your advice makes sense as everybody's individual needs and preferences are different.
I'm still going to go with a combination of individual SSD drives ( no raid and just depends how many individual SSD's I decide to allocate) with the RAID5 array of 4 x 3tb disks for backup (around 9tb usable space ). The machine wont just be used exclusively for video editing and hence this is swaying my decision towards the SSD's.
I could be persuaded to change the RAID5 backup to a RAID10 with the same disks but this would give me more speed and safer redundancy, albeit with only 6TB of usable space. ( I know the backup has nothing to do with the CS6 performance or configuration, just mentioning it ).
FYI, the machine is a desktop, not a laptop, with an ASRock Extreme 11 x79 mb which gives me enough SATA3 connections and has onboard RAID options
Other components are a 3930k processor, 64 gb 8 x 8 Corsair Vengenace 1866 c9 memory kit, and an EVGA GTX680 4G Classified Video Card.
Thanks again for taking the time to reply - much appreciated
I'm looking forward to getting the build up and running
Happy to hear anyone else's thoughts on this topic too.
Kind Regards
Martin.

Configuring Internal DELL RD1000 for Oracle Secure Backup

Hi all,
I have a Dell R710 server running Solaris 10 9/10 which has an internal Dell RD1000 drive. I intend to use this as a target for Oracle Secure Backup but am so far unable to configure the solaris sgen driver to see it as a valid tape/scsi drive.
iostat -En reveals the ff
c2t0d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
Vendor: DELL Product: RD1000 Revision: 0053 Serial No:
Size: 160.04GB <160037691392 bytes>
Also after reboot
-bash-3.00# dmesg | grep -i RD1000
Feb 21 22:02:10 genunix: [ID 846691 kern.info] model DELL RD1000
however after following the installation guide i am still unable to see any /dev/scsi/changer or /dev/scsi/sequential directories.
Any help will be greatly appreciated.
Thanks

I don't know about this tape not appearing to the OS, some other OS related documentation would help you there. This may be due to the fact that this is a removable disk storage device, rather than actual tape.
However I have checked the OSB tape support matrix and this device is not listed, so this is not supported for use with OSB.
Thanks

Would like to know if this is correct disk configuration for 11.2.0.3

Hello, please see the procedure below that I used to allow the grid infratstructure 11.2.0.3 oui to be able
to recognize mY EMC San disks as candidate disks for use with ASM.
we are using EMC powerpath for our multipathing as stated in the original problem description.I want to know if this is a fully supported method for
configuring our san disks for use with oracle ASM becuase this is redhat 6 and we do not have the option to use the asmlib driver.Please note that I have
been able to successfully install the gird infrastructure successfully for a 2 node RAC cluster at this point using this method.Please let me know if there
any issue with configuring disks using this method.
We have the following EMC devices which have been created in the /dev directory.I will be using device emcpowerd1 as my disk for the ASM diskgroup I will be
creating for the ocr and voting device during grid install.
[root@qlndlnxraccl01 grid]# cd /dev
[root@qlndlnxraccl01 dev]# ls -l emc*

As you can see the permissions by default are root:disk and this will be set at boot time.These permissions do not allow the Grid Infrastructure to recognize
the devices as candidates for use with ASM so I have to add udev rules to assign new names and permissions during boot time.
Step 1. Use the scsi_id command to get the unique scsi id for the device as follows.
[root@qlndlnxraccl01 dev]# scsi_id whitelisted replace-whitespace --device=/dev/emcpowerd1
360000970000192604642533030434143
Step 2. Create the file /etc/udev/rules.d/99-oracle-asmdevices.rules
Step 3. With the scsi_id that was obtained for the device in step 1 you need to create a new rule for that device in the /etc/udev/rules.d/99-oracle-
asmdevices.rules file. Here is what the rule for that one device looks like.
KERNEL=="sd*1" SUBSYSTEM=="block",PROGRAM="/sbin/scsi_id --whitelisted --replace-whitespace /dev/$name",RESULT=="360000970000192604642533030434143",NAME="asm
crsd1",OWNER="grid",GROUP="asmadmin",MODE="0660"
( you will need to create a new rule for each device that you plan to use as a candidate disk for use with oracle ASM).
Step 4. Reboot the host for the new udev rule to take affect and then verify that the new device entry will be added into the /dev directory with the
specified name, ownership and permissions that are required for use with ASM once the host is back online.
Note: You will need to replicate/copy the /etc/udev/rules.d/99-oracle-asmdevices.rules file to all nodes in the cluster and restart them for the changes to
be in place so that all nodes can see the new udev device name in the /dev directory on each respective node.
You should now see the following device on the host.
[root@qlndlnxraccl01 rules.d]# cd /dev
[root@qlndlnxraccl01 dev]# ls -l asm*
brw-rw----. 1 grid asmadmin 65, 241 Aug 2 10:10 asmcrsd1
Step 5. Now when you are running the oui installer for the grid installation when you get to the step where you define your ASM diskgroup you should choose
external redundancy and then click on the change disk dicovery path and change the disk discovery path as follows.
/dev/asm*
Now at this point you will see the new disk name asmcrsd1 showing as a condidate disk for use wiith ASM.
PLease let us know if this is a supported method for our shared disk configuration.
Thank you.

Hi,
I've seen this solution in a lot of forums but I do not agree or don't like at all; even if we have 100 luns of 73GB each.
so the thing is, as in any other unix flavor we don't have asmlib***just EMCPOWERPATH running on differentes unix/linux flavors we dont like either udev-rules, dm-path and stuff***
Try this as root user
ls -ltr emcpowerad1
brw-r----- 1 root disk 120, 465 Jul 27 11:26 emcpowerad1
# mknod /dev/asmdisks
# chown oragrid:asmadmin /dev/asmdisks
# cd /dev/asmdisks
# mknod VOL1 c 120 465
# chmod 660 /dev/asmdisks/VOL*
repeat above steps on second node
asm_diskstring='/dev/asmdisks/*'
talk with sysadmin and stoadm guys to garanty naming and persistents in all nodes of your RAC using emcpowerpath. (even after reboot or san migration)

Trying to optimize eSATA and internal disk configurations

I'm trying to optimize the HD setup on my dual 2.5GHz G5 with 4.5GB RAM
major considerations.
- massive itunes library (260GB), and big iphoto lib (25GB) as well
- lots of video editing in Final Cut with large capture files and many video exports
- regular podcasting and other media creation with all my music and photos
- need for regular COMPLETE backups
- speed
Here's the current setup. I have six disks as part of the system
1. internal 160GB disk (maps simply to a MACHD volume)
2. internal 250GB disk (maps simply to a COMMONS volume for Democracy player files, torrent downloads etc)
then on my 4-port eSATA controller card
4x 500GB SATA drives from Western Digital for a total of 2TB eSATA disk space
they are in 2 eSATA enclosures from FirmTek
I'm managing the disks with SoftRAID
Before I get into the problem, how would YOU use this incredible amount of disk space, considering the goals I have? (video, media storage, backup).
Now, The problem
I've been disappointed with the speed of my system and suspect its my HD configuration. I have enough RAM right!?
I've got some raid stripes going on
2 of the 500GB disks (disk2 and disk3) support two "active" volumes
a) a striped ATLAS volume of 800GB (holds itunes, documents, iphoto, basically all media files)
b) a striped VIDEO SCRATCH volumn of 200GB (for working files in FCP, imovie, etc)
the other 2 of the 500GB disks (disk0 and disk1) support two "clone" volumes
a) a mirror MACHDCLONE volume on both disk0 and disk1 (to protect the system drive. I run Super Duper 3x per week)
b) a striped ATLAS_CLONE volume to backup the active ATLAS volume
the COMMONS volume is not backed up in any way. figure i can live without my Democracy files and torrents, etc.
My ideas:
based on my performance observations, my setup above is just wrong, and I don't know where to turn for the best advice. Google is very poor at dealing with such complexity in search results. There are some video advice sites, but they only cover part of my problems. I have a few theories of how I should be using these drives
1. use the eSATA drives strictly for performance benefits, not for backup. consider a USB2.0 drive for backups and use Mozy for offsite backup
2. simplify the disk allocation. No single disk should support more than one volume
3. the video scratch SHOULD be striped in order to benefit from speed. and should be on its own physical disk(s) separate from ANY other function
So I'm thinking
a) stripe two of the eSATAs into a single 1 TB array for my media or ATLAS volume
- this solves me running out of space on the volume (getting closer with the iTunes video downloads every day)
- it's also just physically easier to deal with. I can SEE what drives make up ATLAS alone
- will be easier for me to eventually replace the G5 with an MBP running its own eSATA pc card with easy access to the same ATLAS volume
this still leaves two 500GB eSATA disks around
b1) I could extend the ATLAS volume to an array including a 3rd eSATA disk for a 1.5TB volume. this would allow me to bring COMMONS files onto ATLAS
b2) the remaining 500GB eSATA disk can be video scratch
OR
c1) dedicate 1 500GB disk to VIDEO SCRATCH
and
c2) partition the other 500GB disk as a clone of both COMMONS and the internal System drive
see how CONFUSING THIS IS ?
there are too many permutations of things.
I know I like keeping the system drive simple and internal. Ideally, the second internal disk would mirror this volume, but they do not match in size or brand
part of me wants to stripe all FOUR eSATA drives into a blazing 2TB masterpiece, but it seems like a bad idea to put VIDEO SCRATCH on the same array as ATLAS
Other questions:
should the itunes library get it's own disk altogether? is striping of benefit here?
are there some sites that explain HD management well?
PowerMac G5 2.5GHz 4.5GB RAM Mac OS X (10.4.9) also own a blacbook

Thanks so much for that awesome feedback.
A few points.
I have the dual processor G5, not the quad core. Purchased in Jan 2005.
My RAM pageouts are fine (didn't know what that was until you mentioned it)
Love the idea of moving COMMONS "outside the box"
I used to have my system volume boot from an external RAID, but didn't notice a big improvement, and it meant my G5 would ONLY boot if the eSATAs were powered up. I just didn't like that feel. I want the tower to work in a self-contained fashion, even if I don't have access to all media. I want access to the OS and apps.
I'm unlikely to buy more SATA controllers and enclosers or too many new disks. I'm on a serious budget and want to work with as much of what I have as possible. That said, i just checked out the Drobo and am drooling. I'll wait to see how well it performs for data access (and video) and not just storage.
It sounds dreamy to stripe all four of the eSATAs into a 1.8TB storage megaplex. I imagine they would scream in an ATLAS_BADASS volume, but then I've got nothing left for VIDEO SCRATCH used to capture and render.
The VIDEO_SCRATCH doesn't need to be large, and I think that's where I'm having a conflict. My eSATA drives are way too big to use even ONE as a video scratch, much less striping two of those bad boys just for that purpose
Purchasing a 10K drive for video scratch (or system volume) is not really in the cards yet.
So here's where I sit now:
1. My Media Storage
++ the 4 eSATA drives (2.0TB raw)
I go with the badass steroid injected ATLAS volume striped across all four.
this is my media array and holds all the contents of ATLAS and COMMONS (iTunes, iPhoto, Documents, FCP training videos, ripped DVDs, the works)
2. My System Volume
++ the 250GB internal SATA
move COMMONS out
migrate system volume to this disk
better storage-to-free space ratio
3. My Scratch Disk
a) use the now-spare 160GB internal Maxtor (probably weak and slow)
b) get an external FW800 RAID disk from OWC
http://eshop.macsales.com/shop/firewire/hard-drives/EliteAL/StripedRAID
I'd go with the 160GB or 320GB
4. Backup Plan - level 1 - local
++ use my spare external Maxtor 250GB FW drive
clone the system volume regularly
++ get an external FW drive (like the 1TB My Book Premium II from WD)
clone ATLAS_BADASS regularly
the WD is just $400
i know it's capacity is lower than my super striped RAID, but i don't know of any cheap way to clone ATLAS_BADASS to a 1.5TB drive
5. Backup Plan - level 2 - remote
pay for a Mozy storage account which has unlimited capacity
upload system and ATLAS_BADASS every few weeks
any new thoughts? and thanks again!

Shared Disk Subsystem for Oracle 10g RAC

I am investigating the feasibility of clustering two 220Rs together in an Oracle 10g RAC configuration. Can I use a D1000 disk array for the shared storage between the two nodes? Can you briefly describe how to do it or point me to documentation on how to do it?

hi dstmark,
can you kindly share some information with me? i am thinking of building up a small lab at home using A1000 to build up an Oracle RAC, as a1000 have 2 scsi port and have a build in controller.
but i am unsure about the detail software requirement, as google return some conflict information.
is SUN cluster would be enough? do i need to get something like Veritas Cluster? which may require a license key....
thanks for sharing information.

Error starting Portal or Commerce Server when Configured for Oracle

I've been attempting to configure Portal 4.0 to work with Oracle. I'm running Oracle

properly (have done this many times). However, after I make all of the necessary

the config.xml file (do a text search for an element RDBMSRealm withan

Verify that it looks like this:

I have a MacPro with a 2 500gb and a 250gb internal disks. OSX is installed on one of the 500gb drives, I have the other 500 for data, like finalcut content, and the 250 for bootcamp (windows xp). I also have a 500gb WD mybook premium that I use for time machine.
I would like to add some more space dedicated to video.
I was thinking about was a WD mybook studio pro II 1TB using a stripe set. Here is where it gets messy in my opinion. Should I use FW800, or should I use eSata?
My next problem: I have 1TB of space on a nice fast raid0, but no redundancy. What should I do now? I can get another 1TB mybook (fw400) and do nightly backups, but with what? I would like to use time machine, but from what I read, you can only use 1 disk with it. I could use the software that comes on the mybook to do the backup, looks like it would work, but not all that pretty.
What I was thinking, get a 1TB fw drive and use it for time machine and back up the 500gb OS drive, and the 500gb data drive. I could get another 1tb drive and backup the mybook studio pro II nightly. That way I will never loose more than 1 days work.
The other thing I was thinking was use 2 mybook studio pro 2's and do a software raid1 and mirror them. So i would basicly have a raid 0+1 (mirrored stripeset). the stripes would be hardware raid, and the mirror would be software. From what I hear, software raid doesnt perform that well. Also, what interfaces would I use. I only have 1 fw800 port on the back, and would rather not plug 1 in the back, and 1 in the front. and it would be bad to use 1 fw800 and 1 fw400.
just trying to get the best balance between performace, reliability, and cost.
Any help would be great!
Thanks!
Brian

I would go easy on WD MyBook. Why the fondness for vendor? check out threads and reports on hard drives like MacIntouch.

Put to rest the idea of mirroring. One drive today can saturate FW800. Mirrors are not as useful as backup and its built-in? Another: Apple dropped 0+1 for good reason in Leopard. But you heard software RAID...? Apple RAID is fine, done right.
Invest in a single 4-channel PCIe SATA controller and then you can use SATA drives, and do more than all these other FW drives, cables, all of which run on the single FW bus. Load your 500GB drives there and replace with newer drives (OS X, scratch, data).
If/when you need faster or better drives:

TB drives: http://www.barefeats.com/hard94.html
Add WinClone and/or Windows backup software to backup to one of your existing FW drives, may as well use them for something.
TimeMachine will by default backup all drives. I don't like that. You can have multiple TM sets, nothing to stop you. Definitely don't rely on one backup set or strategy. Definitely use SuperDuper to keep working backups of your system too. You can backup to sparse disk images.
You have PCI Express to add disk controllers, you don't need to rely on USB or Firewire. And if you want to add FW/USB, less trouble and better Mac support with Oxford based OWC Mercury cases.

HRMS Analytics configuration for Oracle EBS

Hi ,
I have to configure HRMS Analytics for Oracle EBS(Referring Configuration Guide for OBIA 7.9.6.3) , I am new to OBIA :
I just started working domain Values (csv files), I have few queries for the same:
1. Is is necessary to Use the query mentioned in the OBIA Setup guide , to get the Domain Values. Can we use different query to extract the Domain Values ?
What is the effect if query is changed ?
2. Some csv are for 11i instance ,so does it mean , it is not required to configure those csv files for R12 ?
Any help in this regard will be highly appreciated.
Thanks,
Razi

Here are the answers to the questions:
1. Is is necessary to Use the query mentioned in the OBIA Setup guide , to get the Domain Values. Can we use different query to extract the Domain Values ?
What is the effect if query is changed ?
A: Not necessairily. The query is there to help you gather the relevant data but this is a functional exercise. If a HR Functional person on your team can identify the relevant domains, events, etc, then you can populate it manually. The goal is to get the relevant EBS domain values and map to the BI requirements. The query is a fast way to get the list of the existing values from the EBS DB.
2. Some csv are for 11i instance ,so does it mean , it is not required to configure those csv files for R12 ?
A: If the COnfig Guide specifically has a section for R12 versus 11..then you need to follow for the version you are on. However, there are general "EBS" configurations that you need to do for both versions. Rule of thumb, if it doesnt specific the version, then it needs to be done for both.
If helpful, pls mark correct or helpful

Internal Order Configuration for a new company

Dear Experts,
Hi! I need help on the Internal Order creation for a new company which previously not maintained the Internal Order. Can Experts can provide me the T-code for the configuration. Any guidance given is very much appreciated. Thank you! _

Hi,
What figures do you have in mind? I/O is a cost collector, thus, if you have a cost which is to be posted on the I/O you should mention when creating a FI/MM document. For example, if you have FI doucment which is posted, let's say, via FB50, you enter your relevant I/O in the document line.

ODBC configure for oracle

Hello expert,
I have two configureation in configuration file for oracle database as follows:
PRODDW.WORLD=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=10.10.10.40)
(PORT=1521)
(CONNECT_DATA=
(SERVICE_NAME=proddw)
PRODDW=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=10.10.10.40)
(PORT=1521)
(CONNECT_DATA=
(SERVICE_NAME=proddw)
I can see "PRODDW" in the ODBC, but PRODDW.WORLD seems exact same as PRODDW in the above. so please tell me what is PRODDW.WORLD? why they are same?

so me folks do silly & needless things?
why are you bothered by seeing duplicate & redundant details?

How to configure hw disk array for ORACLE VM SERVER 2.1.1?

ORACLE VM SERVER 2.1.1 ON DISK SATA ARRAY R0. AFTER A INSTALLATION ORACLE VM SERVER DON;T LOAD

No reason to shout, buddy... Turn CAPS LOCK off, please.
Some more information might come in handy also. Like what kind of hardware you're using.
Otherwise it's going to be a shot in the dark.
In the meantime: try some GRUB-parameters to boot from the right device. That's all I can think of right now.

Hardware Configurations for Oracle 10g AS

Hi,
I'm looking for Hardware Configurations on various platforms which Oracle AS 10g supports. Basically i'm looking for details for these on each supported platforms.
No. Of CPUs
CPU Speed
RAM
Disk Space
I would appreciate if someone point me some document on this.
Thanks,
RK

Those parameters are more of a function of intended use (ie the application and which components of AS involved). There are absolute minimum values to enable installation (not use) of the software in each platforms Install Guide.
For certified platforms, check with you sales contact or Oracle Support.

Recommended configuration for Oracle VM Server and VM Manager

Hi,
Currently we have two dedicated DELL servers (VM server and VM Manager) for which are building an Oracle stack environment.
We are facing a problem which we didn't find answer from Oracle docs or via Google. The problem is that the virtual machines we create in VM Manager can't be connected to the outside world, and we think it's because our host (Hetzner) does not allow ports eth1-eth3 to be connected to the servers, unless we have these servers in the same rack and connected via switch.
Our question is, is it recommended configuration to have VM Server and VM Manager servers in the same rack and connected via switch?
If yes, the next question is, if we need in the future to add one more dedicated DELL server to our configuration to host virtual machines, is it possible if the new third dedicated DELL server is not connected via switch to the two dedicated DELL servers we have already have?
If no, the next question is, what could be the recommended configuration and solution to our problem in our case that ports eth1-eth3 cannot be connected to the servers?
Please do not hesitate to ask if you need more information. I do appreciate your time and expertise. Thanks.

The architectural environment is now done like on this graphic. For security reasons Hetzner hosting service does not allow ports eth1-eth3 to be connected, but in internal network under switch they do.
