Urgent : OS Block header size (convert raw device to filesystem using dd)

Hi,
We need to convert oracle datafiles raw devices to filesystem.
Environment: Oracle 8.1.7 on solaris 8.
Our unix team is unable to tell the value of os block header size to be used for skip/iseek parameter of "dd" command. I know that rman "copy datafile" can be used but it does not help for converting redo log files.
could someone please help.
Thanks.
Rakesh

DB has been shutdown, cold backups have been taken and cannot make any changes at this point.
Is it so tough to know this value ?
Just to clarify, in the following dd command, what should be the value of skip :
dd if=/dev/rdsk/rawfile1of=/data/file1 bs=8192 skip=??? count=100000
Thanks,
Rakesh

What procedures exist for change raw devices to filesystem?

What procedures exist for change raw devices to filesystem?
I understand that only you can:
- Backup Full (System with raw device) and Restore in System with Filesystem
- Export/Import
Specifically I want to know:
A backup (created in MaxDB 7.5 with DB in Rawdevices) can be restored on another System, with DB in file system??
Someone could give me details of the procedure?
Someone knows another method?
Greetings to all.

> Specifically I want to know:

No problem as long as
- the target systems database version is at the same patchlevel (or higher)
- the target database is big enough
- the target system has the same endianess (you can e. g. not import a backup from Windows to HP-UX)
A SAPDB/MaxDB backup has no information about the source filesystem setup, it contains only pages. There has "just" to be enough space to restore them.

Saving from bridge and converting from raw to jpeg

why can I not convert from raw to jpeg in bridge (camera raw) and save to a location different from the original

Yep sure can.
In bridge select your picture(s) then edit in camera raw.
In camera raw look in the bottom left of the camera raw dialog box and you will see a save as button.
This will allow you to save your raw files as jpg, tiff or pngs.

Hidden file when converting from raw to jpeg. How to delete this?

I just found out that when converting raw into jpeg in Photoshop there is a hidden file enclosed starting with ._ Computers don't see them but televisions do. I discovered this because I want to show a batch of my images on a television with a usb of a sd card. It shows my images and after each normal image I get a black image with a questionmark. It says 'cannot read this file' and it shows the name of the image but with a ._ in front of it. For instance garden.jpg and then -_garden.jpg. Computers don't read images starting with ._ but televisions seem to do so. I want to delete these ._ images because I cannot show a slide show of my images on a television. Anyone can help? It seems that this hidden file is incorporated into the jpeg file.
Thanks in advance!

Thanks. I have thought of this solution but these files are not showing when I set it this way. I had a specialist helping me to find this problem and he was very surprised that these hidden files didn't show up in his special program for showing hidden information. Only when going deeper and deeper into this program these files showed on his computer. As they are incorporated into the original file (the jpeg version) you don't seem to be able to delete them. What do people do when they want to show (jpeg converted from raw)images on their tv?
I have a Mac if that helps.

"Convert" from RAW to JPEG?

I normally shoot in RAW so I have the power to make more accurate corrections, if needed. 90% of the time I don't need the RAW image after I've made adjustments, however. Here's what I would like to accomplish using Aperture 3:
-Import RAW images
-Make adjustments to photos as needed
-"Convert" all images 3 stars and below to JPEG and replace (i.e. DELETE) all associative Master RAW images.
What I've been doing is exporting all the images to my desktop after I've made the adjustments, delete all the photos out of the album, and re-import the JPEG images into the album.
Obviously, this is not a very efficient method and a "convert" option would be nice to use if it's present.

The answer is 'No'.
There is no way of doing what you want, many of us in the real world would love that. I for one understand your question from the stand point of I don't want to save every image I ever take in RAW because of the file size.
If you camera can support taking photos in RAW+Jpeg, then there is a route to take that is discussed in this thread:
http://discussions.apple.com/thread.jspa?threadID=2375402&start=0&tstart=0
In essence, with RAW+Jpeg, you take a photo in both formats. Note the Jpeg version captures the photo with your camera settings intact (i.e. Creative mode settings, saturation, picture style 'stuff' as an example).
You import (have to choose in import, bottom right corner...outlined in above thread) and then choose which you want to keep Raw and which to keep in jpeg.
That is, for the moment, the best route to take....if you can. Not all cameras offer Raw+Jpeg.
Best of luck! I know your pain!

How to convert from ASM to regular filesystem

Hi All,
On our RHEL 5.5 machine we have one disk partition managed by ASM (11.2.0.1.0). We wan't to convert it to regular file system. How can we do it?
Regards,
Vinod

Open a Terminal window and paste the following:
# su - oracle
$ . oraenv
ORACLE_SID = [oracle] ? +ASM
The Oracle base has been set to /u01/app/oracle
$ kfod disks=all
Disk          Size Path                                     User     Group
================================================================================
   1:       9214 Mb ORCL:ASMDISK1                            <unknown> <unknown>
   2:       9214 Mb ORCL:ASMDISK2                            <unknown> <unknown>
ORACLE_SID ORACLE_HOME
================================================================================
      +ASM /u01/app/oracle/product/11.2.0/grid
The above will either show you the device, e.g. /dev/..., or the diskname (ORCL) in case you use ASMLib
$ su - root
# /etc/init.d/oracleasm querydisk -p ASMDISK1
Disk "ASMDISK1" is a valid ASM disk
/dev/sde1: LABEL="ASMDISK1" TYPE="oracleasm"
# /etc/init.d/oracleasm querydisk -p ASMDISK2
Disk "ASMDISK2" is a valid ASM disk
/dev/sdf1: LABEL="ASMDISK2" TYPE="oracleasm"
U sing the info from the previous output, the following will permanently remove devices from ASM and create a file system (ext4) that you can mount. When using fdisk or parted, be sure to use the device name, e.g. /dev/sde and not the partition (/dev/sde1).
# parted -s /dev/sde mklabel msdos mkpart primary 1 -- -1
# parted -s /dev/sdf mklabel msdos mkpart primary 1 -- -1
# mkfs.ext4 -L testdrive /dev/sde1
# mkfs.ext4 -L testdrive /dev/sdf1
You can then mount the file systems, for example:
# mkdir -p /u02
# mount /dev/sde1 /u02
All previous information on the devices will be lost.

Convert from RAW to Jpeg on iPad?

Do any of the 3rd party photography apps let you convert RAW images to Jpeg on the iPad itself?
Do any of them let you change the resolution, especially resize to 72 dpi for Web viewing?

I don't know of any applications that can access the actual RAW data.
Even the iPad photos app doesn't really understand RAW ... I believe that it is just showing you the embedded jpg that exists in all RAW formats.
I believe that some of the photo apps (such as "Photogene for iPad") can also read in the embedded jpg and resize / adjust / etc. the photo and then let you send the photo to other apps such as Facebook. How well this will work will depend on the size of the embedded jpg in the RAW format you use. My camera is the 5D mark II which has full resolution jpg files. Other cameras (like the original 5D) have much smaller embedded jpgs.

Converting from global to local filesystem

Hi all, I have a 2-node cluster running Sun Cluster 3.2 in which multiple file systems are currently marked as global file systems (ie the file systems are visible from both nodes and they all have the "global" keyword in /etc/vfstab). I've been requested to turn these (global) file systems into "local" file systems.
Is this done by removing the keyword "global" from /etc/vfstab for each file system on both nodes and then rebooting each node?
Thanks in advance,
Stewart

Hello,
yes, by removing the global flag until the next mount of that vfstab entry.
You can check it in the output of the mount command for that FS.
HTH,

Convert Raw Device to file system based file systems for datafiles [HP-UX]

Hello experts,
Once again in seek of guidance..
I am in the process of migrating my database (Oracle 7.2.3 on HP-UX 10.20 to Oracle 8.1.7 64-bits on HP-UX 11).
Amongst one of our steps is to convert our RAW Device datafiles to File System based files within the same server and version - Oracle 7.2.3 on HP-UX 10.20.
E.g. /dev/vg00/rlvol1 to become /d01/oradata/cmtdb/tbs1.dbf
Is this something possible?
Can i just do the following:
a. Shutdown database (normal)
b. dd if=/dev/vg00/rlvol1 of=/d01/oradata/cmtdb/tbs1.dbf bs=20k
c. chown oracle7:dba /d01/oradata/cmtdb/tbs1.dbf
d. svrmgrl> startup mount
e. alter database rename file '/dev/vg00/rlvol1' to '/d01/oradata/cmtdb/tbs1.dbf'
f. alter database open.
Thanks very much for your replies.
Please tell me about possible problems that i can anticipate.

Using USB-8451, and AD7747 from Analog Devices to measure capacitance and convert the capacitance to digital output

Hello,
I am new to LabView and data aqusition. I have LabView 8.5.1 installed on my laptop, and I studied the Getting Started document of LabView, except the data aqusition chapter.
I have microfabricated a differential capacitive sensor, and now I want to test the capabilities of my sensor.
After asking NI engineers, I have been suggested to use USB-8451 with AD7747 (24-Bit Capacitance-to-Digital Converter) from Analog Devices because AD7747 has I2C serial interface.
I have ordered USB-8451, AD7747, and Evaluation Board for AD7747. And I am waiting for them.
Are there any suggestions about how to connect my differential capacitive sensor to AD7747, and eventually to USB-8451?
You may want to know some further information to answer my question:
*The sensor is similar to the sensor on pages 501, 514, and 515 of "Microsystem Design" book from author Stephen D. Senturia.
*The datasheet for AD7747 can be reached from this link: http://www.analog.com/static/imported-files/data_sheets/AD7747.pdf
*My purpose is to make a very precise and accurate "displacement measurement micodevice" by using "the change in the capacitance" during the motion of the mobile fingers of the sensor.
As an initial challenge for myself, I will feel satisfied if I can measure the capacitance change in my sensor when I apply an external mechanical disturbance to my sensor. For example, there must be a change in capacitance if I just swing my hand from top of the sensor region.
I am looking forward for your reply,
Thanks in advance,
Sincerely,
sriverfxtr

Hi Aaron,
Here you go, this is made with a USB-8452.
When you run the code tick the power en dac enable box on.
Maybe you can help me with my problem, I want to use a fiber to sense light from a led.
Do you use any fiber hardware with the TCS3414?

Transport tablespace from raw to cooked

Hi
I have a tablespace which contains raw devices
What is the best way to copy this tablespace to some other database which has filesystem rather than raw devices?
Both hosts and destinations are Oracle 9.2.0.6.0 on hp unix

Hi,
How about ftp, scp if they have fast network connectity
else tape drive.
and you would to use dd in on the source side to convert it from raw device to cooked file system at source or directly at the target.
I suppose you have different question if yes then please elaborate.

Anurag

Restore from RAW

Hi,
I have installed a database on a RAW file system.
Now, my database got crash..
How can I takeoout all the DBF files from that raw system to a normal filesystem?
Regards,
Indraneel

Hi,
This is the famous Unix dd command.
<quote from Metalink Note 120934.1>
Copying raw devices to filesystem
This can be tricky because we must
offset the header block for the raw device. You will need to contact the OS
vendor to find out how large the OS header block for the raw device is so that
it can be offset with the skip command. Also make bs equal to a multiple of
db_block_size (setting to equal db_block_size is recommended)
% dd if=/dev/<raw device> of=/path/<dbf> bs=<BlockSize> skip=
<SkipInputBlocks> count=<# of blocks (bs) in the datafile used by oracle
(optional)>Regards,
Yoann.

Multiple Black and white conversion from raw or jpgs

Hi All
Any help would be appreciated.
I have 300 wedding images taken on raw and jpg. I now want to convert them all to black and white. Any way I can do this without doing it one at a time (whether using raw or jpg files)?
Hope someone has the answer or else I need to fork out £500 for CS4!!
Clive

Hi
Thanks for reply. I am able to open and convert from raw ok, what I don’t know if I can do is process multiple files that have been changed, i.e. to black and white?
I don’t think PE8 will actually do this.

How do I convert multiple RAW files to JPEG with the same settings?

I have a considerable number (800) RAW files to convert to JPEGs. I am happy to convert them in batches requiring similar settings to save time whilst of course, leaving the original RAW files to make more individual adjustments if required later.
I thought there was a way of doing this in small batches to save time but can't recall how to do it.
Can anyone help?

Many thanks Barbara and dj_paige.
What I didn't mention is that I'm using PSE 5 with ACR 4.6, if its relevant. I'm thinking of updating to the next version when its out in the hope that it will run with Windows 7 64 bit or I may go to Lightroom.
I can now see that I can batch convert a whole folder of files using "process multiple files" as dj_paige suggested but that is too many at once as the settings I choose won't be relevant for all the pics in the folder.
I was hoping to batch convert say 5 or 6 similar photos at a time with the same settings. I'm not quite clear what you're suggesting but I'm hoping that its a "work round" using two stages to achieve this.
I can't see a list of open files within ACR to ensure that they are all selected as you suggest.
What does clicking Open rather than Done mean? Does this amend the original RAW file to the settings selected so that if I then "process multiple files" on the whole folder to convert from RAW to JPEG they will in fact have already been processed in smaller groups so I can convert without applying any further changes?
If so, what settings should I apply to "process multiple files" to ensure a simple conversion of file type rather than any further adjustments?
Any further help on this would be much appreciated.
