Oracle Restore and Recovery

Hello.
Guys I`m pretty new to Oracle and I been trying to restore our backup from Live Database to Our Test Database.
This is what i did.
After installing the Oracle 11g (11.2.0) on our Rhel6 environment, I try to create the folder structure to Test Server same as on Live Server.
After that I "startup nomount pfile='directory'" then created the spfile.
Then I copy the backupset and control file from Live Server to Test Server and restore the control file.
I alter Database to mount mode then go to rman to restore Database.
It all goes well but when I try to recover Database I receive an error.
This is the Error = RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 8929 and starting SCN of 811164225283.
I try to ignore this error and proceed to opening the database;
Alter Database Open resetlogs.
But then again I receive this error.
ORA-01092: ORACLE instance terminated. Disconnection forced
ORA-00704: bootstrap process failure
ORA-39700: database must be opened with UPGRADE option
Process ID: 8020
Session ID: 3 Serial number: 4461
Can some one please help me on how to do this?
I`m really new to oracle and I dont know what to do.

Sir,
Thanks for your assistant.
I have successfully restore the Database.
Now my problem is after recovery I cannot access the EM.
Here is the error shown.
"503 Service Unavailable
Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details."
Is this the cause of my recovery?
Should I turn off EM first before I recover?Just to expand on what Hemant said, the dbcontrol has two parts. One is the repository, which is a bunch of tables in the database. The other is the configuration, which is a bunch of files buried under ORACLE_HOME. The two have to be in sync in ways I don't fully understand, but when you replicate a database from one host to another, especially if any kind of database rename is involved, you are getting the repository from the source system and laying it down with the configuration on the target system. Bottom line, exactly as Hemant said, drop and recreate at least the repository. I do both the repository and the config.

Database is in the pending status after restore and recovery.

Stop the EM console and then restart it. I expect all is OK then.

[HELP] Problem with restore and recovery to new host

Hi, guys!
I have been trying for two days, but still cannot get it to work.
I have taken a full hot(online) backup with archive logs as well as the control file and SPFILE, and then copied the backup to the new host with the same directory structure and settings. Finally, I have tried to restore & recover the database on the new host but failed during the restore process.
Both the original host and the new host have the same Oracle installed down to the patch level. I couldn't figure out the proper solution to this problem base on my limited knowledge about Oracle DB.
Could anyone help me out here? Any advice would be appreciated!

a) Does the directory structur exist on the new server :

Yep, I have doubled check the directory structure that get in the way, and they are all exist.
Would it be something to do with the folder permissions?

b) Apparently a RESETLOGS has been issued on 07-Nov. Which controflile backup do you have restored and mounted on the new server ? It should be the one after the RESETLOGS.

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.

Restore and Recovery problem-XP reinstall

I have a N100 laptop that I am trying to reinstall XP operating system. I have the recovery discs. Started the process in the Rescue and Recovery menu. Part way into the process after putting in the first disc the process will go no further. Just to review how I got thru the menu. I chose option Restore my entire hard drive. then selected backup from CD/DVD. then I get a message: to restore from CD/DVD either insert final C disc or insert final discs of recovery discs. nothing happens when inserting the disc. also-when I restart the computer it always goes to the Rescue and Recovery menu. I can't get a normal Windows startup. Any suggestions of how to get at least to a normal Windows startup and avoid getting to the R and R menu or how to re-format the drive?

Hi dawcary,
I dug out my old x32 that has the recovery discs. The version of Recovery is the same as yours.
Booting from the R&R disc it eventually comes to the window with the two options that you describe, plus a third option to restore factory settings. Choosing to restore to factory settings wipes the drive and installs the predesktop. If you reboot at that point, it will go into the predesktop and that window will then only show the two choices that you listed above.
I don't know why yours doesn't show that third option.
At this point, it sounds like the predesktop is installed on your hard drive and nothing else. Rebooting might be bypassing the cd drive and booting into the predesktop. You probably already did this, but it's the only thing I can think of. Put your R&R disc in the cd drive and start the machine. Press F12 at startup and in the list of bootable devices that comes up, choose cd drive. That "should" give you the third option to restore to factory.

T42 HD replaced, can't get restore and recovery disc to work properly

Hello Support Team!
I purchased a ThinkPad from a company going out of business and was happy with it until the hard drive started to freak out. I replaced the hard drive with a new Western Digital 250 GB and ordered the recovery discs from the place in Atlanta. The discs arrived and I thought I was ready for my new computer. I'm following all the directions in the install, changing the startup to boot from the CD. I get the Recovery Welcome Screen and try to click on Restore Factory Settings. At this point, I get a screen that says "In order to proceed, your system must be rebooted". I haven't gotten past this point now matter what I try.
I like this little machine, but I'm afraid I can no longer breathe new life into it????
Do you have any suggestions?
Thanks!
slhackett
Solved!
Go to Solution.

OK, that's a good start.
Have you wiped the drive before attempting to install the OS? If not, now would be a good time to do it.
Download the PC Doctor for DOS bootable CD, burn a disk and boot from it.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/1ety48ww.exe
Wipe the drive clean (under utilities), run diagnostics on the rest of the system.
If everything comes back clean, re-try installing the OS.
Good luck and keep us posted.
Cheers,
George

Backup and Restore and Recovery

I just recently ran the Backup for my NB255-N245 Notebook with Windows 7 Starter. I did not use the Online Backup but used a USB drive with 128GB of capacity. After doing this I was looking to see what was on the drive because it seemed only 2GB of space was used. I on see 2 items 1 named Notebook and another file MediaID.bin. I am curious what is on this drive and what can be restored or recovered with it? I was originally trying to make a copy of the C drive so I could restore it from the original files, if I am explaining that correctly. This being I think there may be a corrupted file somewhere. I did find out apparently recovery disks seem to be needed to do what I was going to do but not sure if that is correct?

There is a lot of information around, but I will try to explain it in simple terms from my head (sorry, I won't provide links).
Anyway, here is how it is supposed to work.
You must create a user who will be designated as a Data Recovery Agent (DRA).
Do the following on a domain joined workstation - could be a VM.
Encrypt a file using this account so that EFS certificate is created for the DRA.
Export the certificate and export private key. Delete private key during the export.
Save the exported certificate into the safe. Delete exported certificate from the workstation. Optionally, if it was a VM, delete a VM too.
This leaves you with account for DRA that only has the public key, but not the private key. This user can encrypt EFS files, but cannot read them. This is your DRA account. You don't use it for anything else but as a DRA.
So, configure Data recovery policy, using your prepared account as DRA.
That's all.
When you need to recover files, get a new (clean) domain joined workstation - could be a VM.
Get certificate from the safe.
Create a new user JohnDoe.
Import a certificate from the safe to JohnDoe.
Now JonhnDoe has both private and public key and can read EFS encrypted data.
Decrypt the data as you like.
When you are finished, destroy JohnDoe and workstation (VM).

Single Tablespace Backup, Restore and Recovery

Hi Experts,
I need your kind help. Actually I want to take hot backup by RMAN for a particular TABLESPACE ..
I know this is possible. My question is when I restore a tablespace to any other test database
I need to create new database or I can restore it to any existing database? Just like adding new tablespace??
To recover this tablespace I need to archive log backup ?
How I can open the database on which I m going to restore/recover this particular tablespace ???
Regards,
Rizwan

You cannot copy a tablespace from one database to another using the normal Backup/Restore methods.
You have to use the TTS (Transportable Tablespace) methods.

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Restore and recovery cases, please add any if i am missing any

in an up database, datafile gets corrupted
in an up database, system file gets corrupted
in an up database, datafile lost
when you start database, log file shows corruption
Please add

I am not sure that what exactly you are trying to do, sorry for a dry comment! There are a lot of different cases which are defined in the B/R guide. I must say that you finish them all first reading the B/R guide side by side. Once you are done, read Rama Velpuri's 8i Backup and ecovery guide and practise it. Once you are fnished from both, I doubt that ther would be anything left .
Just my 2 cents.

Error in Check DB after RESTORE and RECOVER

Hi Team,
System was partially restored and recovered due hardware failure.
We had 3 file systems that had to be restored and in one of them we has "/oracle/BWP/sapdata8/temp_2/temp.data2" data file.
After the restore and recovery , the system was up.When ran check DB , the get the below error message and when i checked in DB02 , everytime when trying to see the datafile inside PSAPTEMP , there is a short dump with the same error message listed below.
Database error text........: "ORA-01157: cannot identify/lock data file 256 -
see DBWR trace file#ORA-01110: data file 256:
'/oracle/BWP/sapdata8/temp_2/temp.data2'"
When checked the restore , looks like "oracle/BWP/sapdata8/temp_2/temp.data2'" was not restored.
Kindly help to check how to correct this error. Even my online backup's are failing.

Hello Priyanka,
how did you restore your database?
The temporary files are not included in a backup, because they are not needed for a recovery - that works as designed.
After the recovery you have to add these files again.
If you would have used brrecover for restoring/recovering your database the temporary files would be added automatically.
Check the documentation here:
http://help.sap.com/saphelp_nw70/helpdata/EN/6e/4c37b85dc7f24d88f177396dc45645/content.htm
Now you have to do this manually like this:
shell> sqlplus / as sysdba
SQL> ALTER TABLESPACE PSAPTEMP ADD TEMPFILE '/oracle/BWP/sapdata8/temp_2/temp.data2' REUSE;
Regards
Stefan

Backup and recovery questions

Hi,
I am a newbie in Oracle database 11g Release 11.2.0.1.0 and Oracle Linux and I have questions regarding backup and recovery.
I used the “Schedule Oracle-Suggested Backup” and have it run nightly to back up to local disk. In the Backup Setting, on the Retention Policy, I selected “Retain backup that are necessary for a recovery to any time within the specified number of days (point-in-time recovery) day = 7”
With the setting above, I checked the “Manage Current Backups” and I have many back sets for SPfiles, controlfiles, datafiles, and archivelogs for the last several days. However, for image copies, I have only one set and it get over write nightly. With the configuration above, is that true that I can only recover to any point in last 24 hours?
My goal is to be able to recover any “point-in-time” in the past 5 days, should I change my Retention Policy to “Retain at least the specified number of full backups for each datafile” to 5 backups (each full daily backup)? Please provide some advices. Thanks

By looking the following, it looks like by default its 24 hours but it depends upon the recovery window you choose.
Enterprise Manager makes it easy to set up an Oracle-suggested backup strategy for backups to disk that protects your data and provides efficient recoverability to any point in the a recovery window of your choosing. (In the simplest case, examined in this section, this window is 24 hours.) The Oracle-suggested strategy leverages Oracle's incremental backup and incrementally-updated backup features to provide faster backups than whole database backups, and faster recoverability than is possible through applying database changes from the archived log to your datafiles.
The Oracle-suggested backup strategy is based on creating an image copy of your database. This copy is rolled forward by means of incrementally updated backups. Oracle Enterprise Manager schedules RMAN backups jobs for you to run during the overnight hours.
For each datafile, the strategy calls for backups as follows:
At the beginning of day 1 of the strategy (the time the first scheduled job actually runs), an incremental level 0 datafile copy backup. It contains the datafile's contents at the beginning of day 1. In a restore-and-recovery scenario, the redo logs from day 1 can be used to recover to any point during day 1.
At the beginning of day 2, an incremental level 1 backup is created, containing the blocks changed during day 1. In a restore-and-recovery scenario, this incremental level 1 can be applied to quickly roll forward the level 0 backup to the beginning of day 2, and redo logs can be used to recover to any point during day 2.
At the beginning of each day n for days 3 and onwards, the level 1 backup from the beginning of day n-1 is applied to the level 0 backup. This brings the datafile copy to its state at the beginning of day n-1. Then, a new level 1 is created, containing the blocks changed during day n-1. In a restore-and-recovery scenario, this incremental level 1 can be applied to the datafile rolled forward on day n-1 to the beginning of day n, and redo logs can be used to recover the database to any point during day n.
The datafile copies used in the Oracle-suggested backup strategy are tagged with the tag ORA$OEM_LEVEL_0. The level 1 incremental backups for use in this strategy are created for use with datafile copies that are so labelled. You can safely implement other backup strategies without concern for interference from the backups for the Oracle suggested strategy.
There are also Oracle-suggested strategies that use tape backups along with disk backups, but those are beyond the scope of this chapter.
