How to multiplex datafiles, controlfiles on different disks?

Hi, Sir...
I want my database to have two control files, data files on different disks..
In XE, after installation, data files, control files as follows (you know)..
D:\Oracle\XE\oradata\XE\Control.DBF, SYSAUX.DBF, SYSTEM.DBF, TEMP.DBF, UNDO.DBF, USERS.DBF
How to multiplex datafiles, controlfiles on different disks(such as E:\Oracle\XE\oradata\XE\......)
Thank you...
Regards,
Cusco

shutdown the database, copy the control files to the new directory, modify the control_files parameter
startup
you cannot multiplex datafiles (you would have to do that at the os level with mirroring etc)

How to multiplexing control files in ASM instance???

Hi Folks
I have an Oracle DB10g R2 with ASM in which the unique control file is in one group of ASM.
My question is how to multiplex the controlfile and redo logs???
Very thanks,
Wilson

Hi, you can use the OMF feature of ORACLE to move the controlfile into the ASM.
1. you create a backup controlfile: ALTER DATABASE BACKUP CONTROLFILE TO '/home/oracle/control.bac';
2. you specify the locations:
- ALTER SYSTEM SET db_create_online_log_dest_1='+ASMGROUP1'; -- RMAN will restore one mirror of the controlfile in each of these locations!
- ALTER SYSTEM SET db_create_online_log_dest_2='+ASMGROUP1';
ALTER SYSTEM SET db_recover_file_dest='+ASMGROUP1'; -- this will make RMAN restore the controlfile in the flash_recovery_area!
3. you create a pfile from spfile:
- CREATE PFILE FROM SPFILE;
4. you archive the current redolog:
- ALTERSYSTEM ARCHIVE LOG ALL;
and SHUTDOWN IMMEDIATE
5. you edit the pfile by removing the entry for CONTROL_FILES!!!
- and after this: CREATE SPFILE FROM PFILE;
6. you use RMAN to restore the controlfile in the ASM:
RMAN> STARTUP NOMOUNT;
RMAN> RESTORE CONTROLFILE FROM '/home/oracle/control.bac';
RMAN> ALTER DATABASE MOUNT;
RMAN> RECOVER DATABASE USING BACKUP CONTROLFILE;
RMAN>ALTER DATABASE OPEN RESETLOGS;
Hope this helps,

How do I move my photo library to a different disk partition?

How do I move my iPhoto library to a different disk partition?

Drag it to a partition or disk image formatted as Mac OS Extended. If you want that copy to be an active iPhoto library and not a backup, also launch iPhoto with the Option key held down and point it to the new location.

OCR and VOT disk, in the same asm disk or different disks ?! and how ?!

What Oracle recommends regarding the OCR and Voting disks in Rac 11gR2 on ASM ?!
Making them under the same disk or different disks ?!
and how ?!
Thanks a lot,
Regards,
Gehad.

Best practice is that OCR/Voting should be under ASM. Making them under the same disk or different disks depends upon the ASM diskgroup. If we want to keep it on seperate failover groups then we should create muliple failover group.
For external : 1 ; Normal : 3 and higher : 5 asm diskgroups.
I hope i would be clear ith my answers.

W2k8R2 Windows Backup - BMR on different disk configuration - How to move one parition of three parition to an other raid-disk?

Hello folks,
I need your help in following situation.
My source-system has 1 RAID5 (600GB) over 5 HDDs. On the RAID-Disk are one primary partition (250GB) and 1 extended partitions (350GB).
Because the hardware is out of support, I will migrate it to new hardware-server. I must minimized the downtime and the administrative effort. So I can't reinstall a new windows-installation, because 4 different software-licences are binding on SID. Additional
a DFS-R is configured, so I need some hours to reconfigure it.
The new destination-system has one RAID1 (300GB) that I will use it for windows-system, and one RAID 6 (1TB) that is planed for data.
I has make a full backup (with all Critical) by using Windows Server Backup to a NAS storage. Than I has boot my destination system from Windows Server 2008 R2 media, and will make a recover. All Hard Disk is detected, after I install the storage-drivers. When
I confirm the last step in windows-server-backup, windows-backup stop with error "Not enough space on harddisk 0"
How can I move the extended partition to harddisk 1 (RAID6) durring BMR??? I cann't exclude the volume in backup-procedure, because the DFS-R is installed with some share on this disk.
Has anyone a idea?
Best regards

Hi,
I'm afraid we will not get it resolved. BMR will restore the partition information so you need at least a 600GB disk/RAID to restore both Drive C and D - it will create partitions on disk/RAID but cannot be separated restore to different disks/RAIDs.
How about get another 300GB disk and change your system RAID from RAID1 to RAID5. (Or change RAID1 to RAID0 but of course you will lose fault tolerance ability).
If you have any feedback on our support, please send to [email protected]

How can I split my current video into several segments. To put on 3 different disks. Can I do this with out losing all the work?

I need help. I have completed my video and now realize it is too big for a single DVD. Is there a way I can split the video and not lose the current info so I can put video on 3 different disks?
Thank You

Thanks for the update. Looking forward to your results from further searches for that .iso file.
If you burn a Timeline content to a video file saved to the computer hard drive, you can use Publish+Share/Computer/and one of those choices to get a video file (.mov, .mpg, .avi, wmv, mp4, m2t). But, this route does not allow for menus. You can take the saved video file and transfer it to USB Flash Drive or memory card, and, if your player supports that, you can playback the file with the player.
When you burn a Timeline content to DVD-VIDEO on DVD disc, menus are supported. And, what you have on the DVD after the burn to disc are two folders (OpenDVD and VIDEO_TS) in the correct disc system format. It is the VIDEO_TS Folder on the disc that has the video files and menu files for DVD-VIDEO format.
When you take the Timeline content to Publish+Share/Disc/DVD, but use Folder (4.7 GB), you end up with a saved folder which contains the same OpenDVD Folder and VIDEO_TS Folder that you would have gotten from the direct burn to disc. But, now you need to take just the VIDEO_TS Folder from the saved folder and get it to a DVD disc in the correct disc system format. You do that with a free 3rd party software such as ImgBurn.
If you go the ISO Image route, your DVD video files (video and menu et al) are saved as a file in format represented by the .iso file extension. It is essentially a copy of your DVD-VIDEO data including menus. The .iso image produced can be taken to DVD disc to produce the DVD-VIDEO on DVD disc.
So, in the case of burn to folder, you are looking for a saved folder with OpenDVD Folder and VIDEO_TS Folder inside.
In the case of the burn to ISO Image, you are looking for a file with the .iso file extension.
The Save In: location of the burn dialog should point to where you are going to find the folder or file after the burn to.
Please consider. We will be watching for further developments.
ATR
Add On...have you told me yet what is exactly shown in the Save In field of your burn dialog?
C:\Users\owner\Documents or something else?

RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE

제품 : RMAN

RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE
==========================================================
PURPOSE
이 자료는 Oracle 9.2 이상의 RMAN에서 사용 가능한 MAXSIZE 기능에 대하여
설명할 것이다.
How to restore archive logs with limited disk space
Old Backup을 사용하여 RMAN으로 database를 recvoery할때, 모든 archived
redo logfile들을 Restore할 destination의 disk space가 모자란 경우를 종종 만난다.
이러한 경우 여러 개의 restore and recovery job으로 나누어 수행한다.
즉, 첫 번째 restore and recovery job이 끝나면 archived redo logfile들을 지우고
다음 적용될 것들을 restore한다. 그리고 다시 Recovery를 수행한다. 이러한 작업을
원하는 시점까지 recovery를 하기위해 반복적으로 수행한다.
Oracle 9iR2(9.2.0.x)부터 RMAN은 MAXSIZE option을 제공하는데 이것은 archive log
file이 restore될 disk의 space를 control할 수 있게 해 준다.
만약 disk space가 매우 제한적이라면, 즉 예를 들어 모든 archive log의 size 합보다
disk free space가 적다면 MAXSIZE option을 사용하는 것은 매우 유용하다.
이 OPTION이 기술되면 RMAN은 Media Manager에게 disk space 크기에 부합하는 만큼만
archive log들을 restore하도록 한다. 부가적인 restore operation들은 restore된
마지막 archive log가 적용될 때마다 발생한다.
MAXSIZE option은 이러한 작업들을 하나의 rman job으로 처리하게 해 주고
실수를 하지 않게 해 준다.
아래는 MAXSIZE를 설명하기 위한 예제이며 총 6 단계로 구성되어 있다.
STEP 1: Add data to the database to enforce log switches
STEP 2: Backup the database and archive logs and delete the logs
STEP 3: Add additional data to enforce new log switches
STEP 4: Remove the data file and simulate a database crash
STEP 5: Restore the data file from the backup
STEP 6: Recover the database using MAXSIZE
위 예제는 Unix와 Windows 모두에 적용될 수 있다.
STEP 6 는 다음과 같은 조건으로 두 번 수행될 것이다.
1) MAXSIZE가 archive log size보다 작은 경우:
이 경우 RMAN-6558 Error message를 만나게 된다.
그러므로 MAXSIZE를 archive log보다는 크게 설정해야한다.
2) MAXSIZE가 archive log size보다 큰 경우:
예를 들어 여러 개의 archive log를 포함할 수 있을 정도로 크게 설정하면
restore/recovery는 user에게 transparent하게 수행되어진다.
즉 archive log들은 restore된 후 applied되고 deleted되어 진다. 다시 새로운
archive log들이 restore되어지고 applied된 후 deleted 되어 진다. 이러한 작업은
recovery가 끝날 때까지 반복되어진다. 이러한 작업들이 진행되는 동안 RMAN은
아무런 Message도 발생시키지 않는다.
# Step 1: INSERT enough new data to generate log switches
create table rman_tst (col1 varchar2 (10));
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 2: BACKUP the database and the archive logs automatically
# and then delete the input
run {
backup database format='/web01/usupport/krosenme/admin/backups/db_%d%s%t'
plus archivelog format='/web01/usupport/krosenme/admin/backups/arch_%d%s%t'
delete input;
# Step 3: INSERT enough new data to generate new log switches
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 4: REMOVE users01.dbf file and crash the database
mv users01.dbf users01.org
shutdown abort
# Restore is now needed as the data file is deleted. The backup was
# taken before the new data was added to it, thus archive logs are
# needed to bring the database up to date
# Step 5: RESTORE the data file from the full backup
run {
restore datafile '/web01/usupport/krosenme/oradata/kro_920/users01.dbf';
# Step 6: RECOVER
run {
recover database delete archivelog maxsize 10 K;
# This will fail with RMAN-6558 as the archived log has a size of 16 KB,
# which is bigger than MAXSIZE limit of 10 KB. So the error is expected
# and MAXSIZE works as designed.
# Now rerunning STEP 6: but with MAXSIZE 50 K
run {
recover database delete archivelog maxsize 50 K;

cold backup means offline backup, you shut database normally and copy datafiles to another location.
i think operating system does not matter that much but it is RedHat Linux Enterprise Server.
backing up archivelogs whith rman script which is:
run {
allocate channel c1 type disk format '$BKUPLOC/arch_%d_%u_%s_%p.bkp';
change archivelog all validate;
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
backup archivelog time between 'SYSDATE - (30*60/(60*60*24))' and 'sysdate';
release channel c1;
so here is the details.
1. because everything is lost, we restored all files(datafiles, controlfiles, redologs etc) from offline backup meaning copied all files from another location to corresponding location.
2. want to apply archive logs which were created after cold backup till disk failure and we have these archive logs with backups which were taken by rman.
So
first of all, we want to register these archive log rman backups(because these backup information does not exist in restored controlfile)
and then restore them and then apply them.
we need rman commands to register these backups and restore them.

How to recover datafile.when control file auto backup is off

hi friend
i took hot backup of my database using following command
rman>backup database;
in my case controlfile auto backup is off.
and i have lost my all controlfiles as well as datafiles except spfile.
i have recovered control file using dbms_backup_restore package.
know i am able to mount database using following command
rman> startup mount;
when i wrote following command
rman> restore database;
i got following error
RMAN-06023: no backup or copy of datafile name found to restore
enven i have backup of datbase.
can anybody tell me how to recover datafiles in this case.
thanking you
sohail

hi,
I think you might have a problem here as the error from RMAN is described in the following metalink note
Doc ID: Note:100565.1
You should change you backup script to be something like
rman {
backup database include current controlfile;
do you have any earlier backups of your database?

How do I create a new boot disk from an existing one?

I have a G4 Quicksilver with internal PATA disk, running 10.4. I want to upgrade the internal disk from 40 GB to 160 GB. I have installed a second disk and can see it fine, but what I really want is to put the system on the new disk and have it be the one and only boot disk in the system. Is there a straightforward way to do this? Is a carbon copy cloner the way to go? Will that have problems with the different disk sizes? Will it handle bad blocks properly? Isn't there a way to just use drag-and-drop?
Once I have made a copy, how do I make it the boot disk? Do I have to swap it into the PATA "master" position to do this?

Cloning And Backup Tools
A bootable clone is an exact copy of your drive which is capable of booting your computer. Making a copy of your computer which is capable of actually starting the computer requires special copying procedures. Some people just back up data files but if you have problems you have to reinstall all your operating system and all your applications. With a bootable clone you just start up from the backup drive and clone back everything.
To copy files from one hard drive to another hard drive you can use:

How do i get rid of low disk space message popup HP tools drive E on pavilion g7-1219wm notebook pc

How do i get rid of low disk space message ( you are running out of disk space on Hp_Tools (E popup HP tools drive E on pavilion g7-1219wm notebook pc. It is very annoying. I am i school and I have noticed it since downloading different assignments from my college black boards.

Thanks Banhien for your quick response. However my system shows no backup schedule to disable. I do have a 'Manage Space" link and a Turn on schedule link and change settings link along with Restore options with 3 options-' restore all user files- select another backup to restore files from and recover system settings on your computer. If I click on 'Manage Space link', it gives me the option to 'Select how disk space is used by Windows back up'- then there are two options: 'data file backup'-which indicates i can free up space by deleting file backups, and the other option is 'system image' which is greyed out. Upon clicking on the option (view backups) under 'data file backup option'- it shows the current data file backups on my hp_tools (e the date of the file is displayed and the amount of usage- it gives me the option to delete- should I click the delete button?
banhien wrote:
Hi,
Please try:
Click Start, type "Backup and Restore," and press Enter. This brings up Windows Backup which is a little different than system protection.
In the middle of the Window you should see that the backup is on a schedule. Disable this.
Save your changes.
Delete the backup folder on the E:
Reboot notebook and verify that this resolves the issue.

[SOLVED] - Changing the root file system to a different disk

Hi,
I ran out of disk space on my / partition so I decided to buy a new hard drive, and copy everything over (but with different sized partitions). Hoewever, Arch is still using the old / partition rather than the new one.
My new home partition is mounted on /home, as I expect. But for some reason, both the old and the new root partitions are mounted on /. Furthermore, I know that the old disk is being used for the root filesystem because conky tells my that it's 94% full, which is how full the old / on my old disk was.
Here are the things I tried:
First of all, I changed my fstab so that the root partition on my new disk gets mounted as /. (I also changed it for my /home partition similarly). Here are the relevant lines from my fstab:
LABEL=new-hitachi-root / ext3 defaults 0 1
LABEL=new-hitachi-home /home ext3 defaults 0 1
UUID=3c1c1940-693f-4428-aa89-65e1403241f7 /old-home ext3 defaults 0 1
UUID=4a84f8ae-4bad-4acf-8573-1a7b244b416c /old-root ext3 defaults 0 1
After this, gparted reported that my old root partition was mounted under both / and /old-root. My new root partition is mounted under /, also. (So I have two partitions mounted under /, my old and new root partitions. However, the system is using the old root partition, since conky still tells my that / is 94% full).
I'm not sure what else to try. I tried messing around with /boot/grub/menu.list, but I'm not sure how to modify it, I keep making my system unbootable. At the moment it looks like
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/4a84f8ae-4bad-4acf-8573-1a7b244b416c ro
initrd /kernel26.img
(or it did look like that, before I modified it). That seems to be right, because the root entry says (hd0,0), which is the same as /dev/sda, which is the disk where my new root partition is.
Cheers for any help! I'm pretty stuck until I can get some more space on my root partition.

karol, thanks. Any idea how to get it to point to my new disk? I tried
root=/dev/disk/by-label/new-hitachi-root ro
but I couldn't boot from that, I got loads of errors... it couldn't find proc, it didn't even know the host name, loads of other errors. What is the new naming scheme?
bangkok_manouel, do you mean grub? I modified /boot/grub/menu.list as described above, is there anything else I should do?
Edit: I didn't post the whole fstab file, but boot is definetly in there. Actually, I'm still booting from the old disk, since I didn't want to boot from the new one until I got root and home right. (Is this bad?)
My whole fstab:
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0

PSE 11 (OS X): Help! Catalog has just decided my photos are on a different disk

I've been running PSE on my Mac for several years without problems. I just downloaded about 3,000 new photos from my camera, apparently without problems, but when I clicked on one of the thumbnails, PSE couldn't find the photo. On further investigation, I realized that while the photos had downloaded to the usual place, ~/photos/download, the catalog was now looking for them in the same directory but on my BACKUP disk (I have a second hard drive that I use to keep a copy of my main disk). I have no idea how this has changed or why, as I've never manually moved anything to the new disk, and have no idea how I'd tell PSE to look on a different disk anyway, but it seems to have decided to keep the same directory structure but now to look for everything on a different disk. How can I correct this? I can get PSE to find my newly uploaded photos if I copy them to the backup disk, but this is not what I want - it's supposed to be a backup disk!
Thanks for any suggestions, both about what might have gone wrong and (especially) about how to correct it.
Best,
Richard Stanton

Hi,
Can you please check Edit > Preferences > Camera/Card reader pref > "Save Files In" preference?
Also, for the current situation, you may reconnect the files using File > Reconnect > All Missing Files. You would need to manually locate path ~/photos/download and click Reconnect.
Hope this helps.
Thanks

Restore Oracle with brtools to a Windows server with different disk structure

Hello gurus,
Is it possible to restore Oracle to a Windows machine that has different disk structure than a source machine?
E.g. source machine had disks C:, D:, E: (on which Oracle data files were distributed), but a target machine has only disk C:
Database is backuped with brtools.

Hi
I did some mass changes using a script... to be honest I'm not sure if I did it to restore FROM a different location, or TO a different location.
You could also use Brrestore option -m|-mode to restore the datafiles to a new location.
Check online help -m|-mode - SAP Database Guide: Oracle (BC-DB-ORA-DBA) - SAP Library
For instance the here under command will restore datafiles #10 to #20 to the /tmp directory
brrestore -u / -b beokfyeu.pnd -c -m 10-20=/tmp
You could find datafile ID by querying view dba_data_files
select FILE_ID, FILE_NAME, TABLESPACE_NAME from DBA_DATA_FILES;

When one of contolfile is corrupt then how to recover the controlfile?

when one of contolfile is corrupt then how to recover the controlfile?

Let us say we have 3 control files and they are named as "cont01.ctl,cont02.ctl & cont02.ctl" and they are stored in three different mount points (/u01,/u02 & /u03)
first controlfile -> /u01/oradata/prod/cont01.ctl
second controlfile -> /u02/oradata/prod/cont02.ctl
third controlfile -> /u03/oradata/prod/cont03.ctl
1. According to the ALERT log file or any other source let us say the third controlfile got corrupted...
Now , what you can do is you have to shutdown the database and remove cont03.ctl and copy it form cont01.ctl or cont02.ctl :
$ cd /u03/oradata/prod
$ rm -rf cont03.ctl
$ cd /u01/oradata/prod
$ cp -r cont01.ctl /u03/oradata/prod/cont03.ctl
Now, you can go ahead and start the database. The database will start without any issue and it wil be ready for any operations on it..
2. Suppose all the files of the database got corrupted ... First of all you need to have backup of the database... the steps that are needed of this scenario are :
--> shutdown the database with abort option
--> Assuming its RMAN backup .. you have to first start the database in nomount state and you have to restore the contolfile from the last backup been taken and start the database in mount state and then perform the database recovery and open the database with resetlogs option(since you dont have current controlfile becoz you have restored it from a backup) :
Assuming its catalog:
$ rman target / catalog usr/pawd@tns
RMAN> STARTUP NOMOUNT;
RMAN> restore controfile (from autobackup) ; -- in case you have auto backup then use the autobackup option
RMAN> alter database mount ;
RMAN> recover database;
RMAN> alter database open resetlogs ;
After the database gets opened , immediately you have to take the backup..
Hope its clear...Cheers!

Why is Oracle RMAN restoring a datafile to a different diskgroup?

Hello,
When I was trying an RMAN restore of a datafile, I found it is restoring the datafile to a new location. Why is Oracle restoring a datafile to a different diskgroup instead of restoring to the original diskgroup where the datafile was originally present?
1) I have a datafile '+DATA3/slob1/datafile/undotbs2.260.819992871' which is on +DATA3 diskgroup
2) I am taking a backup on to +FRA diskgroup
3) I then offline and delete the datafile 5 using asmcmd to simulate the loss of a datafile
4) I perform restore and recover of datafile 5 from the backup set on +FRA
5) Unfortunately the datafile got restored on to +FRA instead of +DATA3. I realize that the file name can change because it is going to be a new file on ASM but I would assume this will be on the same diskgroup atleast since the control file has it pointing to '+DATA3/slob1/datafile/undotbs2.260.819992871' before restoration.
When I tested on file system, this gets restored on to file system correctly.
Anyone has any idea why the datafile was restored on to +FRA instead of +DATA3?
Below is the screen output of what I did.
