Dear Gurus
Our Platform: Redhat Linux Enterprise Editions5.3 64bit
We are installing Oracle11g r2 Grid(Clusterware+ASM) and want to use ASM for storage OCR,VOTING,DATA and FLASH Storage.
We are not want to use ASMLib.
plz find the shared raw partitions details

ASM Spfile on shared raw device

Hi,
I am building two nodes Cluster on Linux 4 update 5. I have successfully created the CRS. Now I am trying to create the ASM instance using the ./dbca. When I select both nodes to manage diskgroup, during the instance creation, and after I enter the SPFILE file location, I am receiving this message
{The /dev/raw/raw10/spfile.asm.ora location is not valid. The directory "[/dev/raw/raw10/] is not a shared system partition across nodes1 and 2.}
The Oracle:dba has the ownership and read/write permission on this partition.
Your help highly appreciated.
Majid

1) Check to make sure that the partition /dev/raw/raw10 is a shared raw device between the nodes (you can do this by using: dd if=/dev/zero of=/dev/raw/raw10 bs=1M count=x from both the nodes while logged in oracle).
2) Since /dev/raw/raw10 is a raw device, you can not specify /dev/raw/raw10/spfile.asm.ora as an SPFILE location. Alternatively, under $ORACLE_HOME/dbs create a link to /dev/raw/raw10 with the name spfile$ORACLE_SID.ora from both the nodes.
ln -s /dev/raw/raw10 $ORACLE_HOME/dbs/spfile$ORACLE_SID.ora (both the nodes)
HTH
Thanks

SPARC 64bit Clusterware 10.2.0.4 - shared raw device

Dear group,
I have been asked to install RAC 10.2.0.4 SE on Solaris 10 (SPARC). I am not a Solaris admin altough I have done many RAC installations on RHEL4/5.
Does anyone have suggestions/pointers to documentation (apart from the docs on OTN which I already consulted) on how to place OCR and vorting disk on shared raw devices? The setup is unlikely to use any multipathing but will rely on a low end SAN for shared storage. I am especially interested in the proper use of the "format" tool (I know for instance that I need to start from cyliner 1 for ASM slices).
So far all I found were documents explaining SFRAC, Sun Cluster etc which I either don't have at my disposal or can't use due to license restrictions.
On a comparable single-pathing Linux setup, we'd simply use fdisk to create partitions on the shared disk(s) which then are made available as raw devices thanks to udev.
Thanks and regards,
Martin

Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
Mini DisplayPort–to–VGA adapter implicated
The following sequence of events causes the problem to occur:
Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
I used Apple System Profiler to save a list of identified devices at two points in time:
Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
Many devices are enumerated in the second list that are missing from the first. For example:
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
AppleUSBHub <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
Keyboard Hub@fe110000 <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
AppleUSBHub <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
IOUSBInterface@0 <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
Apple Keyboard@fe112000 <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
and many child devices…
Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
Some devices are discovered even when the computer is in sleep mode. This is how it should work.
The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
Can anyone else reproduce this problem?

Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
Here is an article that may help you with that process:

Raw device not seen after reboot the server

hi,
I hv upgrade kernal in linux 7.2 but when reboot system no raw device found
how can find out raw device

From http://www.fors.com/orasupp/unix/37914_1.HTM
Raw Devices and Oracle - 20 Common Questions and Answers
2. How can a raw device be recognised?
In the /dev directory, there are essentially two type of files: block
special and character special. Block special files are used when data is
transferred to or from a device in fixed size amounts (blocks), whereas
character special files are used when data is transferred in varying
size amounts. Raw devices use character special files; a long listing
of the /dev directory shows them with a 'c' at the leftmost position of
the permissions field, e.g.
crw-rw-rw- 1 root system 15, 0 Mar 12 09:45 rfd0
In addition, character special files usually have names beginning with
an 'r', as shown in the above example. Some devices, principally disks,
have both a block special device and a character special device
associated with them; for the floppy diskette shown above, there is also
a device
brw-rw-rw- 1 root system 15, 0 Apr 16 15:42 /dev/fd0
So the presence of a 'c' in a device does NOT necessarily mean this is a
raw device suitable for use by Oracle (or another application).
Generally, a raw device needs to be created and set aside for Oracle (or
whatever application is going to use it) when the UNIX system is set
up - therefore, this needs to be done with close co-operation between
the DBA and UNIX system administrator.
Once a raw device is in use by Oracle, it must be owned by the oracle
account, and may be identified in this way.

Raw devices versus Cluster File Systems in RAC 10gR2

Hi,
Does anyone using cluster file systems in a RAC 10gR2 installation, specifically IBMs GPFS?
Ive visited a company that is running RAC 10gR2 in AIX over raw devices. Why someone would choose to use raw devices , with all the problems to administer , when all the modern file systems are so powerful? Is there any issues when using cluster file systems + RAC? Is there considerable performance benefits when using raw devices with RAC ?
I´ve always used Oracle stand alone instances over file systems (since version 7) , and performance was always very good. I´ve tested raw devices almost 10 years ago , and even in that time (the hardware today is much better - SAN , 15K rpm disks , huge caches - and the file systems software today is much better) the cost to administer it does not compensate the benefits (only 5% more faster than file systems in Oracle 7).
So , besides any limitations imposed by RAC , why use raw devices nowadays ?
Regards,
Antonio Belloni

Hi,
spontaneously, my question would be: How did you eliminate the influence of the Linux File System Cache on ext3? OCFS2 is accessed with the o_direct flag - there will be no caching. The same holds true for RAW devices. This could have an influence on your test and I did not see a configuration step to avoid it.
What I saw, though, is "counter test": "I have tried comparing simple file copies from an OS level and the speed differences are not apparent - so the issue only manifests itself when the data is read via an oracle db." and I have no good answer to that one.
Maybe this paper has: http://www.oracle.com/technology/tech/linux/pdf/Linux-FS-Performance-Comparison.pdf - it's a bit older, but explains some of the interdependencies.
Last question: While you spent a lot of effort on proving that this one query is slower on OCFS2 or RAW than on ext3 for the initial read (that's why you flushed the buffer cache before each run), how realistic is this scenario when this system goes into production? I mean, how many times will this query be read completely from disk as opposed to use some block from the buffer? If you consider that, what impact does the "IO read time from disk" have on the overall performance of the system? If you do not isolate the test to just a read, how do writes compare?
Just some questions. Thanks.

Devices not discover on bluetooth preferences

I just bought a Sony MDR-1RBT MK2 bluetooth haedset, but my Macbook pro can't find it.
I have followed the procedure of the manual, such as hold down the power button for 7 seconds.
I checked the headset could work with a mobile phone.
My Macbook pro bluetooth must work, because I am using bluetooth wireless mouse.
My Macbook pro purchased in 2010 with OS upgraded to 10.9.1.
What is the possible problem? Are my Macbook pro too old to support?
configuration of Macbook pro: 17-inch, MacBookPro6,1, processor 2.53GHz Intel Core i5, 8 GB Memory, NVIDIA GeForce GT 330M 512MB
Bluetooth:Broadcom, chipset:2070B0

Thank you for your reply. I solved this problem.
Thank you the genius of Apple store.
They helped me to find the problem.
It was because the headset required to press the power button long enough to activate the pairing mode.

ASM spfile on raw device

How do you create a spfile on a raw device, or how do you move one to it?
Any help will be appreciated.
Thanks

Hi all,
maybe I am the only one, but as I understood Alexander's question, he wants to put the ASM spfile on a RAW device, not the database spfile - but I might be wrong. Alexander?
An ASM spfile cannot be kept in a diskgroup. However, if you choose to manage the ASM environment using DBCA, you can specify a shared location for the ASM spfile in course of the initialization of the ASM environment (when you create your ASM instances for the first time using DBCA).
Once the ASM environment has been created, one may use Ned's approach to relocate a spfile of an ASM environment as well. I am not too sure, but I would think that the sqlplus command "create spfile='RAW device' from pfile; would do the trick, too, given that you have a pfile. Now, if you have a spfile only right now, you can create a pfile first using this command and create the spfile in the final destination later. However, in either case, do not forget to change the pfile link after you have performed those steps.
Just my 2 cents. Thanks,
Markus

Network devices not showing up under "shared" in finder bar

Ok so i have a network that consists of a maxtor nas device, 2 win xp pc's, 1 win7 pc, d-link 524 router, and my macbook pro. I would like to be able to transfer files between my mac and the devices and use the printer attached to my maxtor. My issue is that none of the computers show up under the "shared" section of finder or under network. I use to have this issue with leopard but it resolved itself. Now under snow leopard for a couple months and i have yet to get it work. I can access my mac and other pcs from a pc. Anyone know how to get my network to show up on my mac?

Your problem is very common under Snow. At first my shares did not show up under shared in finder windows. I, then, of course, used "Connect to Server" to connect to the shares--both Mac and PC. I found that the more I kept the shares active the more likely they were show up under shared. Then, I discovered that if I kept the computers from sleeping during the period of needed access they would tend to stay in shared without nearly so much keeping the connections active.
If you do not like the above work around, then there are two other possibilities. You can elect to show mounted items on your desktop. Do that and connect to each share. Then, go > users > unlock > + login options > try dragging the mounted shares to the login item window. If successful, then the shares should be available at login.
Another approach is to mount and connect as indicated above. Then, making an alias to the share should at least make things faster.

Shared devices not showing up in finder

Shared devices on my network are not showing up in Finder on my MacBook Air. Problem just began in the last 24 hours, and is limited to just this computer. Have done usual things -- checking, unchecking shared devices in Finder; relaunching Finder; restarting computer. Any ideas?

and i configured following in /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sdb1 -- ocr
/dev/raw/raw2 /dev/sdb2 -- voting disk
/dev/raw/raw3 /dev/sdb3 -- asmdisk group
/dev/raw/raw4 /dev/sdb5 -- asmdisk group
and my question is how node2 can understat these raw device as shared storage?
thanks for any support

hi thanks for your suggestion ,
this may be ok for VMware , but what about for non-VMWare environment?
how can i make raw device as shared storage?
one more, all the docs that i followed on net , configured node1 partitions as shared storage.

Ipod nano 7g not discover any device bluetooh

Hi, my ipod nano 7g not discover any bluetooh device.
I turn on the bluetooht and is "searching" in "discoverable mode" but does not detect any device.
My iphone 5, immediately detects the headset Nokia BH-503, the same as my iPad mini.
Please .... help me!

Have you placed the headset in pairing (discoverable) mode and have you turned off the BT on the iPhone 5 and iPad mini if they are in range?

IPhone 4S bluetooth not discovering bluetooth devices

My iPhone 4S bluetooth is not discovering bluetooth devices, specifically my new Platronics Voyager Pro HD headset which worked just fine with the iPhone 4 even after the recent software upgrade. I noticed that others are having bluetooth discovery issues as well. Will Apple be addressing this problem with a software fix or is this a hardware problem?
CrystalVan

Nevermind! It always helps to re-read the Platronics - how to pair your device instructions. DUH!!!!
