DB를 COLD BACKUP(FULL BACKUP) 받는 방법
제품 : ORACLE SERVER
작성날짜 : 1995-11-21
데이타베이스를 COLD BACKUP 받는 방법
==================================
콜드 백업은 데이타베이스가 정상적으로 SHUTDOWN 된 상태에서 데이타 화일,
로그 화일, 콘트롤 화일을 모두 백업받는 것을 말한다. SHUTDOWN 하지 않고
OPEN 된 상태에서 백업을 받으면 백업받은 내용을 나중에 사용할 수가 없으므로
유의해야 한다.
콜드 백업을 위해서 데이타베이스를 SHUTDOWN 할 때에는 NORMAL, IMMEDIATE
옵션을 사용해야 하며 ABORT 를 사용해서는 안 된다. ABORT 를 사용한
경우에는 SHUTDOWN 후에 다시 STARTUP 하고 NORMAL 로 SHUTDOWN 하도록 한다.
콘트롤 화일과 데이타 화일 및 로그 화일의 위치를 확인하여 이들을 tar,
cpio, dd 등의 명령을 이용하여 백업 받도록 한다. NT 에서는 COPY 명령이나
탐색기를 이용해서 백업을 받으면 된다.
콘트롤 화일 확인 방법
sqlplus에 system/manager로 접속해서
SQL>select value from v$controlfile;
데이타 화일 확인 방법
SQL>select name from v$datafile;
로그 화일 확인 방법
SQL>select member from v$logfile;
위에서 확인된 3 종류의 화일들을 백업받으면 된다.
(오라클은 반드시 SHUTDOWN된 상태이어야 함)
필요에 따라서는 파라미터 화일까지 받아두는 것이 좋다.
파라미터 화일은 $ORACLE_HOME/dbs/init<SID>.ora 이다.
(NT 에서는 C:\ORANT\DATABASE\init<SID>.ora 화일이다.
보통은 initORCL.ora 라고 되어 있다.)
여기서 <SID>는 오라클 인스턴스 이름으로 환경변수 ORACLE_SID 로 지정이 되어
있다.(NT 에서는 REGISTRY에 지정됨)
Hi,
I believe the database is shutdown and started for an export is to avoid a snapshot too old error which could araise when you have consistant=y.Still I do not believe it should be done.
Ok your second oint I would say is complimentary , because even you have a full export when the whole DB crashes.It would be much faster to restore from a cold backup than to create a new DB and import the data.

Force Time Machine Full Backup
I wanted to update my Macbook Pro with a new Hard Disk, after preparing & installing the new HD and then chossing to restore from the Time Machine, i was surpised that the Time Machine showed me only some Backups(Full Backups), and the last full backup was 6 Months old, although i did a TM Backup just before installing the new HD, but apprently it is an incremntal backup, therfore it was not shown in the list.
So my question is how to force a TM Full Backup so that i can just restore it on the new HD. I know i can do it if i deleted all the old Backups, but i want to keep them, is it possible?<?xml version="1.0" encoding="UTF-8"?>

Help me understand.
What is considered a Whole backup? Is a Whole backup the same as a full backup... the same as a cold backup? If I have different drives, should I backup everything on each drive or should I only backup certain files? If only certain files... which ones?
I understand that if I run in NoArchiveLog Mode, then I am only able to restore my database from a cold backup if there is a failure more or less.
So what files are important in a NoArchiveLog Mode Oracle 8.1.7 Database? I read the Backup and Recovery guide and I'm trying to figure out if I should copy the redo logs or not. The books says "Oracle recommends that you do not backup a current online log, because if you restore that backup, the backup will appear at the end of the redo thread."
I'm thinking that the statement in the book is for individuals running in archive mode.Help me understand.

r.- If you are going to backup the database to get a cold backup you have to backup : the datafiles, the controlfiles and optionally the redo log files but that is not needed if you shut the database down in a clean way. Shutdown a database in a clean way is to close it some of these options ( NORMAL, IMMEDIATE, TRANSACTIONAL )

Is backup full database , is backuing up controlfile ?
Hi
i am on 8174
is that enough to cold backup the database?
shutdown immediate;
startup mount;
run {
allocate channel t1 type 'SBT_TAPE';
send 'NB_ORA_POLICY=....';
backup full format 'bk_%U_%t' (database);
or do i need
backup current controlfile; ?
i can see here http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76990/rmanconc.htm#436070
this statment "A full backup is different from a whole database backup, which is a backup of all datafiles and the current control file."
is that means
backup full database , is backuing up controlfile ?(i think yes) and is restoring from it requires any archivelogs?(i think no)
Thanks very much
Edited by: user9145417 on 25-Aug-2010 16:42The reason to have the current controlfile is that it keeps all the information of the database. If you lose the entire machine, it will be much more difficult to recover to another machine without that controlfile. That is one reason that control files are multiplexed, so that you do not lose all of them.
With 8174 I don't believe there was a method to always included it automatically like with 10g. So yes...always backup your control file with an exact statement.
Will you need archive logs? If you want to do a complete recovery you will need all the archivelogs that occur after the start of the backup untill the time the database crashes.
Do you need to backup the archivelogs within this script? Well that depends if you can think of any circumstance that would require you to recover to a point in time using the backup taken before this one.

Is it possible to take a full backup without shutting down an instance?(10g
Hi. everyone.
Is it possible to take a full backup without shutting down an instance?
The db version is 10gr2.
As far as I know, in order to take a full backup of a database,
one need to shutdown a database.
Our db environment is a RAC environment which has two nodes.
Yesterday, I heard from a hardware vendor that we do not need to shutdown
instances(2-nodes) in order to take a full backup.
Best Regards.Hi,
>>As far as I know, in order to take a full backup of a database, one need to shutdown a database.
In fact, a database operating in NOARCHIVELOG mode is necessary to shutdown the database in order to perform a full backup (Cold Backup), but otherwise a database that is operating in ARCHIVELOG mode, then is possible to perform a full database backup with the database in a open state. (Hot Backup)

RMAN Backup Issue when Full backup file was missing
Hi,
On : 11.2.0.2 version, Recovery Manager
RMAN Backup issue
Last week we had the NFS Issue where we backup the files onto NFS.
The problem occurred in the below sequence
Saturday the backup was successful
Saturday before deleting the backup files they are copied to tape
Deleting the backup files via OS command
Sunday Full backup started but due the NFS issue backup failed(Killed the instance and restarted)
Did the RMAN Incremental backup which worked on Monday
On Tuesday RMAN started complaining and started doing the Full backup.
no parent backup or copy of datafile 1 found
no parent backup or copy of datafile 3 found
no parent backup or copy of datafile 24 foundSony any idea why the Incremental backup worked on Monday but not on Tuesday
Regards
NMOk here is why I would like exact filenames..
1) to speed the time of recovery. I am much more familiar with traditional recovery methods than RMAN, and while I myself installed and suggested RMAN for backups, our other (11i) database does not use RMAN and so I am more familiar with traditional recovery. So to be able to recover quickly I want to have these files as close as possible to the original names so that I can use my standard script (from a trace file) to recreate the control fiile. If I can get RMAN to spit out the filies with original names but keep RMAN for making the backup, I may ditch the rman bacjup script in chron and write a traditional hot backup script which copies the files the old fashioned way.
2) to reduce cloning time. The RMAN duplicate command is not as good as I thought. I was actually easier for me to restore RMAN backups first to a box that has all the same paths, and THEN shutdown (cold) these files and copy them cold to another server, and restore from there. Agaiin if I can get the original file names, I could choose to do recovery either way (RMAN or traditional) in a real emergency instead of being forced to use rman.
3) to be able to switch to a backup file in the FRA without having to rename it. Seems logical if it is already named correctly.

Rman full backup and restoration
Hi,
I am planning to upgrade a oracle 10.2.0.2 RAC database to 10.2.0.4.
If i get any issues during oracle upgradation we need to revert back to 10.2.0.2 again.
I am not pretty perfect in RMAN, so please let me know
1) DO I need to take the full backup of RMAN?
2) Should I take cold backup or hot backup?
3) If my upgradation fails, how to come back to 10.2.0.2 again by using rman backup?
Thanks,

Hi,
My new Oracle Home location is different from the old Oracle Home location.Huh? You would apply the patchset to an existing ORACLE_HOME. Where does this different location come in?
and what operating system are we talking about here?

Is any one please explain me how to revert back to old 10.2.0.2 database with the RMAN backup if get strucked up during the upgradation.
If you please explain with the rman commands then that could be great help for me.

HT1175 Time Machine wants to start with a new, full backup instead of using the existing one
Hi, my Time Machine wants to start a new, full backup, instead of continuing with the existing one on the time Capsule.
Looking a the Troubleshooting guide, I've found the following piece of info, which is, as 99% of the times with the troubleshooting guides, totally useless to resolve my problem...
Message: Time Machine starts a new, full backup instead of a smaller incremental backup
There are three reasons why this may occur:
You performed a full restore.
Your Computer Name (in Sharing preferences) was changed--when this happens, Time Machine will perform a full backup on its next scheduled backup time.
If you have had a hardware repair recently, contact the Apple Authorized Service Provider or Apple Retail Store that performed your repair. In the meantime, you can still browse and recover previous backups by right-clicking or Control-clicking the Time Machine Dock icon, and choosing "Browse Other Time Machine disks" from the contextual menu.
It should be noted (hence the uselessness of the guide) that:
-I haven't performed ANY full restore
- I havent changed my computer name
- My computer has not had ANY repair, much less a hardware repair. Neither recently, nor in the 9 months I've owned it.
Which puts me back to square one, with the marginal improvement that now I have a way of browsing my old backups.
In the event I decide to start all over again, will there be a way for me to "sew" the two backup files?
Or will I always have to go the silly way around?
Anybody has any idea?
Thank you for your time (machine/capsule, your choice;-)Hi John,
no, that doesn't have anything to do with my problem.
Just look at the image below.
Time Machine thinks that the disk I've always used to do my backups has none of them.
If I open the disk with Finder, obviously they are where they should be.
It is even possible to navigate them as per the instruction reported above, but even following Pondini's advice #s B5 and B6 (which are more applicable to my problem) didn't solve the problem.
Actually, not being a coder, I'm always scared of doing more damage than good when I have a Terminal window open.
My question is: how is it possible that Apple hasn't thought of some kind of user command to tell the idiotic Time Machine software that a hard disk backup is a hard disk backup, no matter what?
Estremely frustrating and annoying: I'm wasting HOURS in trying to find a solution to a problem that should not have arisen in the first place...
Have a nice weekend

ACS 5.3.0.40 On-demand Full Backup failed.
Hi,
I have ACS 5.3.0.40 Primary Secondary Authenticators , of which the Scheduled backup has stopped.
When checked the :
Monitoring Configuration >
System Operations >
Data Management >
Removal and Backup
> Incremental Backup , it had changed to OFF mode. without any reason.
The same was observed earlier too.
I have made the
Incremental Backup to ON and intiated the
View Full Database Backup Now. But it wasn't successful and reported an Error:
FullBackupOnDemand-Job Incremental Backup Utility System Fri Dec 28 11:56:57 IST 2012 Incremental Backup Failed: CARS_APP_BACKUP_FAILED : -404 : Application backup error Failed
Later i did the acs stop/start "view-jobmanager" and initiated the On-demand Full Backup , but no luck, same error reported this time too.
Has any one faced similar type of error /problem reported , please let me know the solution.
Thanks & Regards.One other thing; if this does end up being an issue with disk space it is worth considering patch 5.3.0.40.6 or later since improves database management processes
This cumulative patch includes fixes/enhancements related to disk management to avoid following issue
CSCtz24314: ACS 5.x *still* runs out of disk space
and also fix for
CSCua51804: View backup fails even when there is space in disk
Following is taken from the readme for this patch
The Monitoring and Reporting database can increase when as records are collected. There are two mechanisms to reduce this size and prevent it from exceeding the maximum limit.
1. Purge: In this mechanism the data will be purged based on the configured data retention period or upon reaching the upper limit of the database.
2. Compress: This mechanism frees up unused space in the database without deleting any records.
Previously the compress option could only be run manually. In ACS 5.3 Patch 6 there are enhancements so it will run daily at a predefined time, automatically when specific criteria are met. Similarly by default purge job runs every day at 4 AM. In Patch 6 new option provided to do on demand purge as well.
The new solution is to perform the Monitoring and Reporting database compress automatically.
2. New GUI option is provided to enable the Monitoring and Reporting database compress to run on every day at 5 AM. This can be configured under GUI Monitoring And Configuration -> System Operations -> Data Management -> Removal and Backup
3. Changed the upper and lower limit of purging of Monitoring and Reporting data. This is to make sure at lower limit itself ACS has enough space to take the backup. The maximum size allocated for monitoring and reporting database is 42% of /opt( 139 GB). The lower Limit at which ACS purges the data by taking the backup is 60% of maximum size Monitoring and Reporting database (83.42 GB). The upper limit at which ACS purges the data without taking backup is 80% of maximum size Monitoring and Reporting database (111.22 GB).
4. The acsview-database compress operation stops all services till 5.3 patch 5 , now only Monitoring and Reporting related services are stopped during this operation.
5. Provided “On demand purge” option in Monitoring and Reporting GUI. This option will not try to take any backup, it will purge the data based on window size configured.
6. Even if the “Enable ACS View Database compress” option is not enabled in GUI then also automatic view database compress will be triggered if the physical size of Monitoring and Reporting database reached to the upper limit of its size.
7. This automatic database compress takes place only when the “LogRecovery” feature is enabled, this is to make sure that the logging which happens during this operation will be recovered once this operation is completed. ACS generates alert when there is a need to do automatic database compress and also to enable this feature.
8. Before enabling “LogRecovery” feature configure the Logging Categories in such way that only mandatory data to log into Local Log Target and Remote Log Target as Log collector under System Administration > ... > Configuration > Log Configuration
This “LogRecovery” feature can recover the logs only if the logs are present under local log target.
9 This automatic database compress operation also performed only when the difference between actual and physical size of Monitoring and Reporting database size is > 50GB.
10 The new CLI “acsview” with option “show-dbsize” is provided to show the actual and physical size of the Monitoring and Reporting database. This is available in “acs-config” mode.
acsview show-dbsize Show the actual and physical size of View DB and transaction log file -
I bought a new external hard drive for backups, but time machine won't do a full back up.
I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?
When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.Triple-click anywhere in the line below to select it:
tmutil compare -E
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot. -
DPM Express Full Backups Causing SQL timeouts
Hi,
We run a SQL 2008 R2 failover cluster on Server 2008 R2 SP1 connected to an Equallogic SAN. The SQL failover cluster is fully servicepacked and installed the latest cumulative updates.
We have all our databases in full recovery mode and protected by DPM 2012 SP1 with latest cumulative updates.
The protection groups for SQL are configured to synchronise every 60mins and 1 express full backup every night. Every time the SQL express backups run the SQL server experiences timouts and end users report applications timing out. In the SQL server Application
logs I see Event ID 833 numerous times, these only occur as the express full backups take place. Every time the express full backups run we see the same timeouts and event logged that I/O has taken longer than 15 seconds to complete:

I was under the impression that DPM SQL backups would remain online during the backup.
Is this normal?
Any way to fix this issue?
Thanks,

A copy backup will not truncate the logs but a full backup will and it will also stamp the database once it does a full backup. -
Hello all, I could use some help with my iPhone 4, I hope this is the best place to ask!
The Problem:
I want to do a full backup of my iphone to either itunes or to icloud. Unfortunately the iphone got wet and isn’t working properly. The phone turns on and still works, but the touch screen no longer works. I have a passcode lock on the phone so iTunes will not allow me to backup it up until I type in the passcode (which I cannot physically do). WiFi had been turned off before it got wet so it won’t connect to any known WiFi networks either to backup automatically to iCloud.
What happened:
I had been travelling for 6 months and went tubing on a river with my iphone in a dry bag. Unfortunately the dry bag failed and filled with water ruining my iphone.
What I’d like to do:
It’s an old phone and I was planning on buying a new iPhone anyway. I would love to do a full backup to either iCloud or to my computer so when I get a new iPhone I don’t lose anything. I’ve already connected it to my PC and downloaded all the photos and videos off the phone so at least I haven’t lost that, but I would like to be able to recover all the text messages, WhatsApp messages and notes I had created during my 6 months of travel.
The last time it was backed up to my pc or to icloud was in April, so there are 6 months worth of very meaningful data I would love to keep to remind me of my travels!
Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??
iTunes recognizes the phone just now and I tried upgrading the phone to iOS7 in the hopes that it would first backup and then upgrade. Unfortunately all that happened is the phone upgraded to iOS7, but it didn’t backup to iTunes. Now the phone is stuck at the iOS7 welcome screen and I can’t do anything else with it.
Any ideas or tips would be welcome!
NOTE: This is NOT a jailbroken iPhone.If there is no other way around this, is there anyway to completely wipe the phone then??
The Apple store agreed to give me a new iPhone 4 as a warranty replacement for $150 (I travel a lot and I have a factory unlocked phone, so this is still worth it for me). But before I trade it in, I would like to make sure all my data is backed up on the device first.
When I try and restore the phone now on iTunes, it says I have to turn off Find My iPhone on the phone first before I can restore it. Now since I can't use the screen I can't really do that.
So how do I completely wipe the iPhone???
Thanks! -
How to create a new full backup alongside existing one?
I have recently reinstalled my MBP from scratch and installed some apps from scratch as well. I still have my old TM backup in a sparsebundle on my NAS (a ReadyNAS NV+).
I now would like to create a complete new full backup alongside my existing one. Or put differently, a new folder/backup inside the Backups.backupdb inside the mounted sparsebundle. Currently I see a folder called "XYZs MacBook Pro". I'd like that to be renamed to something like "XYZs Old MacBook Pro" and create a new full backup under "XYZs MacBook Pro".
I understand you end up having multiple folders inside Backups.backupdb if you have many Macs (with different MAC addresses). I only have one Mac, but want TM to treat my old previous backup (of the same MPB, hence with the same MAC address) as if it was from another Mac (with a different name).
With such a setup, I can still access backups from my previous installation of the same hardware by selecting another volume from TM (by holding Alt when clikcing at the TM icon) or with tools such as Back-In-Time.
Is there any way to achieve this? My sparsebundle is large enough to hold another full backup alongside the old one.
Thanks

But wait, you said if I erased the disk I get a new UUID. I did not erase it but I moved all files into a /Previous folder (after booting from the install DVD), then installed the system new, and then moved user data (and some Library and some application stuff) back from /Previous. So, I guess, I have no new UUID for my internal disk.
Ah, yes, that is different ("reinstalled from scratch" usually means erased). If the disk was never erased, it will still have the same UUID. But since you've moved or replaced virtually everything, it will all get backed up anyway.
I'm not sure why you did all that; the old +Erase and Install+ and +Archive and Install+ options no longer exist for Snow Leopard: there's just Install, which replaces OSX without touching anything else.
I wanted to have a *really clean* install as my old systems seemed to be messed up with some bad settings.
So, back to my original question: how can I make the new "XYZs MacBook Pro" appear alongside the old "XYZs MacBook Pro" and switch volumes when I start TM using the Option key?
Why would you want to do that? You can view and restore from any backup.
I figured that way I can keep all old backups from the old installation and not have TM retire old stuff. And start a new one from scratch for the new installation where things will get retired. Basically keep the two backups apart from each other and not see any of the old stuff unless explicitly mounted using the option key.
If I follow your approach, what happens to old files of the old disk/UUID? Will they get retired eventually? Would my original idea work as envisioned or would it retire old things nevertheless? If the latter is the case, it is of no use and your suggested approach is the better one.
Is there maybe a ay to force TM to start a new full backup?
Back up to a different place: a different HD or partition, or erase the current one.
Guess that's my only option then. I created a full bootable backup to en external USB disk using Carbon Copy Cloner. Erasing the internal disk and copying back using CCC will create a new UUID then I guess ...
I will try that in the next couple of days and report back here. Thanks a lot for all your help and explanations so far, much appreciated! -
Time Machine repeatedly does full backups, including FileVault while logged in
So let me preface this - for months I'd hoped for a way that Time Machine could backup my FileVault encrypted account without logging out. Last night Snow Leopard spontaneously started doing this. I know many may think that I'm looking a gift horse in the mouth, but read further and hopefully someone can help me make sense of this.
Last night I attached my external 1TB USB hard drove to my 15" MBP (spring 2010 model) running OS X 10.6.7. It started doing a Time Machine backup automatically, as usual. Since I was logged into my account that uses FileVault (a massive home folder - 220GB) I expected a fast backup of things only outside my home folder. As i looked at the details, however, i quickly realized that it was backing up all 270GB of data on my hard drive - including my FileVault account while still logged in!
At first i thought i just got lucky - i'd been craving this feature for years and it just happened to me without even doing anything. Curious guy that i am, i logged out of my acct with my USB drive still attached to see what would happen. After FileVault cleared out space in my home folder, it did _another_ backup, that took about 10 minutes to complete. This seemed strange so i logged back in and started another backup manually. To my utter shock, it started doing the whole 270GB over again!
I even cleared out my TM drive, erased, reformatted, checked permissions, etc etc and did the same on my system drive, hoping that it was just a matter of broken permissions. No change.
So there's two things going on here and i'm pretty concerned about both:
1) Why is TM backing up my entire encrypted home folder while i'm still logged in??? Apple has clearly designed TM and FV to NOT work this way for data integrity reasons and the fact that it's happening has me freaked out a bit over the reliability of my backups.
2) Why is TM doing full backups after each time i login to my account? If i stay logged in, it appears to only do incremental (normal) backups but if i logout, then re-login and allow the hour to pass and let a backup start on its own, it starts the whole 270GB again.
I'm getting to the point of wiping the system and starting from scratch but since i presently live in a country with no Apple store and extremely poor internet access, that prospect horrifies me
any ideas?
many thanks,
-TimThanks for the input Pondini -
I tried deleting the file as mentioned in #A4 and it still had the problem. Last weekend i finally got a brand new hard drive and reinstalled OSX 10.6.3 from scratch, then promptly applied the 10.6.7 combo update. I purposely chose to NOT import my old user from backup and instead set up everything again manually (royal pain, but the only way i could be sure that i wouldn't bring the problem with me). Today i whipped out my TimeMachine drive and set it up for backups. I crossed my fingers and it AGAIN started backing up all 250+GB of my system from within my FileVault protected account.
My wife's MBP is still running 10.6.4 and i'm beginning to wonder if his is an issue with 10.6.7 since i'm relatively certain i didn't experience this before that upgrade.
I've checked my wife's exclusions under Options and her home folder is NOT in that list, yet her TM is not attempting to backup everything until she logs out of her FV acct.
In response to Linc Davis, _yes_ it was backing up my info into a sparsebundle file, not just the raw unencrypted data, which is extremely strange.
If i DO add my home folder to the exclude list, will it still be backed up when i log out?
At this point, i'm thinking my next steps are:
1) try a different TM backup drive, even though i've wiped and checked my current drive numerous times
2) downgrade to an older version of Snow Leopard to see if 10.6.7 is the culprit
Any other ideas?
