My car has a flat tire. The manufacturer packed a spare tire, jack, and lug wrench in the trunk of the car at no additional cost, and described the process in the owners manual. I want to replace the flat tire without using any method other than the one involving the use of the tools designed for and provided for the job.
Is there any book or site, which describes more scenarios and explanation on manual backup and Recovery(without RMAN)

Oracle 11g Backup and Recovery

Hi ,
Please let me know which is the best book for Backup and Recovery perferbable RMAN which also include Oracle 11G fundamentals for recovery .
Looking forwrad for your responsce ..
Thanks
Nitin

rajeysh,
I do agree with you on the book and the online docs but nowadays i do think that the oracle online documentation could have wrong or misplaced information. So reading the online documentation along with a book that has some hands on experience parameters should be the best solution. Also you can support the knowledge by searching the internet.
Regards.

Dear 789393,
What you can possibly do is go to the amazon and search for RMAN. See the results and search web and comments about those specific books. You can purchase whichever you want that meets the criteria of yours.

Oracle Backup and Recovery 101: where can I get more information?

Hey everyone. I'm a pretty new Oracle DBA and backup and recovery is something I want to learn as much about as I can.
I read a blog about "how to be a good DBA" and it really drove home the importance of backups. I know how important they are, I just want to learn more.
What I mean is, I understand a lot of the high level concepts. It is pretty much straight forward. What I am looking for is something that really goes down in the internals of what is going on behind the scenes so I know what is going on.
I thought it would be extremely beneficial for me to learn about user backups. Granted, RMAN is the direction my company is heading to, but right now, we are doing user made backups. My thinking is that if I can get a solid grip and understanding of backup and recovery, user made backups, it will make the transition to RMAN much easier. That way, when I am working in RMAN, issue a command to do backup, I know the equivalent of a user backup and what is going on.
I hope that makes sense.
Is there a recommended book that goes over backup and recovery in depth?
I'd like to learn about all the user-made backup commands that can be executed at the command line (example, putting a tablespace in backup).
Since backups are essential to the life of a DBA, I thought the more I know, the better off I would be.

You can always find good information from Oracle document site,
Oracle® Database Backup and Recovery Basics
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/toc.htm
Oracle® Database Backup and Recovery Advanced User's Guide
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/toc.htm
User managed backup is quite different from RMAN backup. For RMAN backup you need to get familiar with the RMAN command syntax and configure.

Backup and Recovery Plan

I know very little backup and recovery plan in oracle using RMAN or any agent.
Is this right way to summarize the backup and recovery plan for 24 X 7 system required to have 99.99% up time.
The backup and recovery strategy recommended below is based on the premise that database is set ‘ARCHIVE LOG’ mode.
The database files must be backed up using an RMAN backup (or tape agent i.e. Oracle Agent for Veritas) to allow for recovery of corrupted files or files on failed volumes. These archive logs and RMAN backups should be written to a directory on a separate volume from any other database files. It is not recommended to store RMAN backups in the Oracle Control files. The RMAN backups and archive logs and document images are then written to tape in accordance with the GFS backup strategy.
Any suggestions and inputs would be helpful
Thanks

It was a generic note for the productions databases, i.e. have db in archivelog mode, take backups through RMAN to TAPE or on disk which will be used in case of disaster or media recovery.
You need to decide what kind backup and recovery policy you need to have and where you are going to copy/place the backup.
Just keeping in mind the following:
1. How quickly the database can be recovered in case of disaster/media recovery.
2.Make sure no transaction are lot, in another way, recovery until point of time.
3. What kind of policy you need, incremental, cummulative or full backup.

Need help in oracle data recovery

Friends ,i need help in oracle data recovery.
I had an oracle 8i database running on windows.
For some reason Windows operating system crashed.
It is not booting up.
I dont have current backups.But my database physical files are in the disk.
Controlfile,datafiles and redo log files are there.
Is there any way I can recover my database?
Please help in this issue.
regards
Ajith

HI citrus,
thanks for the reply.
I have installed database 9i on the same PC after O/S reinstallation.
You are saying that ,I need to keep oracle root folder same as that of my old installation ,and copy control files,redo log and data files in exactly same folders as that of old database,and then start the database?
thank you for your patience and support.

Need clarification for cold backup and recovery

Hello Everyone ..
I have much confusion on cold backup and recovery topic.
Already i posted a scanario regarding this and i want to know some clarity points to understand.
1. I had cold backup two days before
2. I am creating an object *(EMP)* and inserting some records then issue log switch continiously.
3. Manually i removed all physical files (datafiles , control files , log files , redolog files ...)
4. then i issued STARTUP FORCE MOUNT;
5. here i am getting error identifying control file.
6. cold backup two days before all files restored
6. then i issue recover database using backup controlfile until cancel;
7. i am trying to issue select * from emp; i am getting error
select * from emp
*ERROR at line 1:
ORA-00942: table or view does not existMy QUESTION IS
After cold backup finished , i created emp table ..
when restoring old back " There is no emp table"
*- then , can i recover emp table ? - If so , please explain about this ..*
Note : REF - LINK https://forums.oracle.com/forums/message.jspa?messageID=11056341#11056341
- Above link says what i did ? . In this thread i am asking concept & logic ..
please do NOT consider as "*DUPLICATE*"

When you recover the database using backup controlfile until cancel, you have to apply archived logs. Did you apply all of them?
If the create command was in the online redo, not yet archived, and you lost the online redo, then you won't have it. This is why you want to have redo multiplexed, it is a critical piece.
In some recovery scenarios, if you haven't lost the online redo, you need to specify those files as if they were archives.
It is normally easier to just be sure you have the latest controlfiles and let Oracle figure it out automatically (which is why you want to use online RMAN backups rather than cold backups). But yes, it is important to understand what is going on for different scenarios. I used to have manual standbys, and one of the disaster instruction sets explained to try to get online redo over to the standby to lose as few transactions as possible. That could still be useful for some snapshot hardware type scenarios, assuming the business is too cheap to do proper failovers.

Backup and recovery oracle XE

Hi, oracle guru.
I have searched in google how to backup and recover to and from removable disk or hard disk (in separated folder) in oracle XE 10g, but I didn't found any.
I tried to use backup and recovery database given from oracle itself, and I analyze which file is added and modified. I do somekind of trial and error action. First, I backup my database and then I copy 2 files (I forgot the names, 1 is about 853 kb, and one is the backup file (about 500 mb)). And then I do some user deletion (I have several users) and then I backup and copy again to different folder from the previous one. Note that I am not using archive log: on.
Unfortunately, when I copy the previous backup (the one with complete users) to oracle folder, the restore database does work until, I guess starting database, it throws error saying that something error in SYSTEM.DBF, thus making my oracle doesn't work, even I canot go to database home page.
My question is that how to backup and recover database to and from removable disk or harddisk with different folder? Which files do I need to copy or should I add backup and recover script?
Thanks for the reply.

Yes, as I already mentioned, previously (assumes) that I have database with several users (say 5 users). And I use backup database and restore database from oracle folder in start menu, and it works perfectly (assuming that I delete one user and then restore database).
However, I tried to copy the backup file (which I mentioned before, but I am not sure the files I am copying is backup file since I only analyzed it). So, I test it. First I backup, and I copy to separate folder. Next, I do some user deletion, and I do backup. Say, for example I want to use that backup file in another computer. I copy the files to oracle installation folder. One in product/database/ folder, and one in flash-recovery area. When I try to use restore database (in start menu), it works, until, I guess, starting database, and it throws error saying that error in SYSTEM.DBF.
So, my point is that, how do I backup my database so that the backup file can be in separated folder (for example in removable disk), thus I can also select backup file to be restored.

Dell Backup and Recovery - Factory Recovery fails, need advice.

Back story:
I have tried this three times on three separate laptops, with poor results. Windows 7 on two of them and 8.1 one one, on all three the recovery partition is corrupt.I first boot it off of a live disk and backup any desired files. Then I boot, press F8, choose "Repair your computer" and discover that "Dell Factory Image Restore" is not one of the available options... so I boot the pc off of a different live disk and remove a bunch of "viruses", then I boot it off of the internal harddrive.In Windows I find that "Dell Backup and Recovery" may or may not be on the pc. It may or may not have ever been run before. If it is absent I download it and install it. When I run DBaR it tells me it needs to update, don't power off or disconnect the machine from the internet, etc. I then wait HOURS for this part to complete. When done it...

Backup And Recovery on 7.2.3

i need information on backup and recovery, please help me.(from begin)
i don't speak english, but don't worry, i read the english.
Thanks you.
Oscar Rojano. [email protected]

i suggest you read the oracle backup and recovery manual sections, or take the course, as this is an extremely important topic.
a cold backup is done when the database is down. to do a cold backup, first shutdown the database. then backup all datafiles. then restart the database. you can use this type of backup if your business can tolerate the database being down for the time it takes to do the backup.
a hot backup is done when the database is up and running. the database must be running in archive log mode. then, a hot backup can be performed by putting tablespaces into backup mode, and then backing up the affected datafiles. whenever you do a hot backup, you must be sure to also back up all archive log files from the start of the backup through the end of the backup. if you must restore the backup, and you don't have the archive logs, your database will not start and you will not be able to get it back.
an export is a backup of selected tables. it is not a complete backup and should not be used if a fast, complete recovery of the entire database is required. it is good if a fast restore of a single table is something you need to do often. be aware of database consistency problems if you are restoring a single table that is updated frequently.
depending on your requirements, you will use one or more of the three backup solutions above.
i would recommend that you use the oracle RMAN (recovery manager) tool, in conjunction with an enterprise backup tool from HP, Veritas, or IBM, to be sure your backups are as complete and reliable as possible.

Making data in tables online and offline - Backup and Recovery

Hi All,
I'm working on a project where the functionality is similar to 'Backup and Recovery' for database tables.
Lets say we have a set of 6 tables T1, T2.... T6. They do have relationship between them. The tables in questions are simple standard tables, which are not table partitioned.
- I want remove the records from live tables based on user entered date ranges and store it in some offline medium.
- I might want make the data online again from the offline medium; Application should be able use that data without any modifications.
- Different offline mediums can be
a) Flat file
b) Different table space
c) Any other secondary medium (like XML, tape..Etc,)
The total number of records will run in millions.
The proposed solution should consider,
1. Performance - Java solutions not feasible. Anything in SQL, PL/SQL or runs in DB itself(tools) are OK.
2. Reliability - Should be highly reliable, Data corruption simply unacceptable.
3. Security - Users should not be able to make out of the file.
Few options include:
1. Use partition
2. Use SQL*Loader
3. Export and import of tables.
My main targets:
1. Reduce space.
2. Increase performance for queries.
Please pass on your suggestions, any help is highly appreciated!
Thanks In Advance!

Few points to note:
1. I agree partition would be right solution, but as I mentioned in my earlier statement, 'The tables in questions are simple standard tables, which are not table partitioned.'. The tables right now are not partitioned and I believe we cannot add/modify partitions, if the table were not created with the partition option. One work around is to build a partitioned table and copying all the properties(indexes,rows,constraints) from the existing non-partitioned table. But I suspect this is highly riskier and we can't afford to it.
2. I need to support Oracle database versions starting from 8.0.6.
3. Flat file is mandatory, others are optional. I can restrict our discussion just for a file.
4. Considering the above points, the only option I could think of is I can move the records from the table to flat file and remove from tables. When required rollback the file data to the table and application would be able to use it. For export/import few options are: SQL*loader, exp/imp utilities, PL/SQL file UTL packages
Thanks In Advance

About Backup and Recovery in a distribuited enviroment

Hi.
I've read that if you more that one DB (say 2) connected in a distribuited enviroment, all DBs must be recovered in case one of your DBs fails.
I'd like to clarify the folloiwng issues:
- It that 100% true, i mean isn't an exception to that rule?.
- What happens if one DB is in archive mode and the other is not?
- Why do i have to restore both DBs if there's one one in trouble?.
- Isn't there a way to tell recovery process that you don't want restore or apply the distributed data, since you know that data is already there (at least in the case of complete recovery)?
Thanks in advance ...!

I couldn't find much info on the topic for 9i (you don't mention your version), but found this in the Backup and Recovery Concepts manuls:
"If the database is a member of a distributed database system, then all databases in the system should operate in the same archiving mode. Note the consequences and constraints contained in the following table.
Mode Constraint Consequence
ARCHIVELOG
Closed cleanly
Backups at each node can be performed autonomously, that is, individually and without time coordination.
NOARCHIVELOG
Closed cleanly
Consistent whole database backups must be performed at the same global time to plan for global distributed database recovery. For example, if a database in New York is backed up at midnight EST, the database in San Francisco should be backed up at 9 PM PST."
Therefore, I wouldn't recommend having one database in archivelog mode and the other not. As far as your last question is concerned, I'd say that Oracle won't try any recovery if there isn't a need for it (if the data is already there), but that could be tested to confirm. I think that you need to read carefully the RAC concepts manual, and try some backup/recovery scenarios hopefully on a test box.
