Restore & recovery test

I have the full offline backup of my development system now I want to perform a restore & recovery test as our golive is very nearer . Can anybody shed the light to perform it from SQL management studio with steps.

You can script it like this:
RESTORE DATABASE QAS
FROM Tape0, Tape1, Tape2
WITH NORECOVERY,
FILE = 4,
     MOVE 'PRDDATA1' TO 'H:\DATA1\QASDATA1.MDF',
     MOVE 'PRDDATA2' TO 'H:\DATA2\QASDATA2.NDF',
     MOVE 'PRDDATA3' TO 'H:\DATA3\QASDATA3.NDF',
     MOVE 'PRDDATA4' TO 'H:\DATA4\QASDATA4.NDF'
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251240.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251410.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251425.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251440.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251455.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251510.TRN' WITH NORECOVERY;
RESTORE LOG TS2 FROM DISK = 'Q:\FROM_PRD\PRD_tlog_200801251525.TRN' WITH RECOVERY;
"Tape0, Tape1, Tape2" is the device that the backup is being restored from. In this case, three tape drives in parallel.
The MOVE statements tell SQL Server where the original DB files from PRD will now be located on the QAS server.
The Q:\ drive here is a location that contains the transaction logs copied over from the PRD system.
Always make sure you use the NORECOVERY option in every step before you are finished applying logs, and use the RECOVERY option with the last log you want to apply. Once you use the RECOVERY option, no more logs can be applied and a new CHECKPOINT is set in the DB, so make sure you get it right the first time.

Database Restore & Recovery from tape

Hi Fellows
I'm about to attempt a recovery from backup tape to a test server, as a 'tape recovery' test. The files I've marked for recovery include (directories including all sub-tree);
Datafiles directory
$ORACLE_HOME/sid/ directory where the sid is the database sid
Control Files
adump, Bdump, cdump and udump directories
Archivelogs directory
Flashrecovery area directory
Redo logs directory
initfile and spfile
With these files recovered (from one point in time), and the dbconsole shut down prior to restore (for the sid) should the database be able to startup afterwards? Is there any other actions I should make? Thanks, David

Thanks for your responses Alok and Santosh
I'm pretty sure the files I have selected should be able to recover the database. The recovery, I think is rightly said, can only be done within Oracle. I'll look into a test of RMAN (I know it should be better) recovery once I've tested this as a 'straight from tape' recovery.
Thanks again, David
Alok and Santosh
I thought I'd put this in as 'aftermath' of the attempted recovery;
I had the server team restore the files stated (basically everything - redo, archivelogs, datafile, controlfiles, init and sp files, even the dump files) - and repalced them into directories made the same as the other server. When I started it, I was able to go into a 'Oracle Suggested' full database recovery, which was successful. I then checked the expdp dump files, 1 taken at the same time of backup as rman - and one directly after the restore), and compared rows - exactly the same. So appears to have worked.
Many thanks, David

Database restore/recovery questions...

HI I am somewhat new to the recovery process and I have just installed a new 2 node cluster on linux itanium and I have created a testdb in ASM. I have backup up the new testdb using rman with a full online backup and including control file. We are not using a recovery catalog and all of the rman backup data is only stored in the control file.
I was planning to use the drop database command to drop the datafiles and then resore the database so that I can test my restore/recovery procedure.
If i use the drop database command it will reove the control file and parameter file so I was wondering how I can get my database back if that is the case because all of the backup data is stored in the control file?
Can someone steer me in the right direction here? How can I recover if the control file is gone?

controlfile backup is crucial to be backed up for this scenario,if yours alls backup stuff exist while controlfile backup (repositry of yours database files as well backup stuff) gone then recovery would be more tricky and complex.

Disaster Recovery Test

Hi,
Can anybody please guide, who'll play the major role in "Disaster Recovery Test"
like functional / basis / abap etc,,,

Hello Mahesh
Everybody has to play a major role , first Basis has to take action then abaper and then for testing Functional people required to put their effort.here is brief excerpt from an article regarding "Disaster recovery for SAP".
It will give all of us an idea about Disater recovery.
When you have your SAP system installed, you don't have a disaster recovery solution.
"SAP has standard methodologies for doing backups and restoring the SAP environment, but there's nothing built into their application that specifically targets disaster recovery,"
In other words, SAP tells you very explicitly what you need to protect, but you're on your own in figuring out how to make it happen. It is common practice among third-party solution providers to ask about disaster recovery, but if you're doing your own thing it is important to be aware of the need for a disaster recovery solution.
Outsourcing vs. building a secondary site:
There are two ways to go about setting up your disaster recovery solution: Outsource or build your own secondary site. Outsourcing may be more convenient and less expensive, especially for smaller companies on a tight budget. Simply approach the outsourcing company with your needs, and they will pretty much take it from there. Graap likens it to an insurance policy, where you pay a premium on an ongoing basis for the security.
If you decide to outsource, ask colleagues for recommendations and spend some time researching prices, which can vary a lot. But make sure the outsourcer can step up to the plate in the unlikely event that you need their services.
Building your own secondary site requires a larger investment up front but the leaves you in full control of your contingency plans rather than be at the mercy of an outsourcing company. If your outsourcing provider falls through for some reason -- such as being in the same disaster zone as your main office during an earthquake for example -- you're in trouble. When building your own site, you can prepare for more scenarios and place it far enough away from your main office.
High availability vs. cost:
Specialists say one of the most important questions to consider is availability and how quickly you need to get your systems back online. The difference between getting back online in 10 minutes or three days could be millions of dollars, so you want to make sure you get just the right solution for your company.
Around-the-clock availability will require mirroring content across two sites in real-time. This enables you to do an instant failover with little or no downtime, rather than force you to physically move from the office to a backup site with a stack of tapes.
Regardless of whether you outsource or set up your own site, a high availability solution is expensive.
"But if that is what it takes to keep your business from going under, it's worth every penny of it".
An added benefit of having a high availability solution is that you can avoid maintenance downtime by working on one server while letting the other handle all traffic. In theory, this leaves a window of risk, but most maintenance tasks, such as backups, can be cancelled if need be.
One consideration for mirroring data is the bandwidth to the secondary site. Replicating data in real-time requires enough capacity to handle it without hitches. Also, a secondary site will require the same disk space as your regular servers. You can probably get away with a smaller and cheaper system, but you still need enough storage space to match your primary servers.
Whatever the choice for disaster recovery, it is vital that both the technology and the business departments know about the plan ahead of time.
Testing your solution:
Ok, so you have a disaster recovery solution in place. Great, you're home free, right? Not quite. It must be tested continuously it to make sure it works in real life. Sometimes management can be reluctant to spend the money for a real test, or perhaps there are pressing deadlines to keep but it should be tested one or two times a year.
Many people who build good plans let them sit collecting dust for years, at which point half the key people in the plan have left or changed positions.Update the names, phone numbers and other vital information frequently and test them, he said. It is for the same reason you do fire drills: When the real thing strikes, there's no room for error.
In testing, consider different scenarios and the physical steps needed to get the data center up and running. For example, many disaster recovery solutions require at least parts of a staff to get on a plane and physically move to the secondary location. But September 11 showed how that is not easy when all planes are grounded.
Costly but vital:
Disaster recovery is not cheap, and it requires lots of testing to stay current, but it could save your critical data.
"Any customer who makes an investment in SAP is purchasing an enterprise-class application, and as such really should have this level of protection for their business". "I can't imagine why anybody would not have an interest in disaster recovery."

TS1538 download of restore/recovery stops before completion,saying it is password protected

Forgot password and wanted to do a recovery. I followed the recommended steps but download of restore/recovery stops before completion,saying it is password protected.

Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3.While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: Data will be lost. You may have to repeat the above many times.

Production server Incremental Backup is restoring in Testing server

Dear All,
Currently our Production database is running in windows 2003 server , Oracle version is 10.2.0.4.0
Now my question is daily incremental backup of production server will be restored in testing server (same configuration in production server
and testing server ) how can i achieve this .....
Regards,
S.Arun

Hi Oradba,
Thanks for your response. I went through the link and we need this only for testing purpose and not for reporting.
We need to take incremental backup and restore it in testing server. Is it possible to do this without RMAN.(Due to some Business reasons)
Thanks & Regards,
S.Arun

Restore recovery area

Hi,
In 10g, there is a command "backup recovery area" to backup files in recovery area.
But I could not find the corresponding restore command to restore the recovery area files.
Anyone how can I restore the recovery area files from tape to disk?
Thanks
Vincent Pek

Hi,
Pending how you've run your backups, Oracle should implicitly know where the backups are located and restore them as appropriate (providing you integrate RMAN with your media management software). If backups were done to disk using standard channels, that's where the backuppieces would be read from for restore / recovery purposes.
Alternatively, if the FRA (for example) has been backed up from disk to tape (allocating the necessary SBT channels) using the correct MML API (e.g. Netbackup, Networker or Omniback), RMAN will read from the tape and restore as appropriate.
RMAN for 8i / 9i would typically back up either straight to tape OR disk explicitly as per the channel allocation (i.e. either to disk or SBT_TAPE). 10G+ introduced the FRA, which would be used as a "staging area" for backups before these are moved to tape, also via the RMAN process.
See RMAN documentation:
Oracle Documentation / Book / Backup and Recovery Advanced Users Guide / Advanced Topics

Conor.

UNINTENDED "Restoration & Recovery" to XP not Vista

After 18 months hard use of my ThinkPad 7668-CTO I decided it was time to 'start over.'
So despite this kind of thing making me nervous, and the hours wasted copying the important stuff,
I embarked on a full restore & recovery to my original factory-set Vista Business by using the 7 CDs provided.
It went fine - neither a glitch, nor complication, nor any heart-stopping moments.
Until the process finished, that is, when I saw my ThinkPad now sported XP, not the original, factory-set Vista Business.
I'd like to know why Lenovo
1. Included only CDs to restore XP on my ThinkPad but not the original, factory-set Vista Business?
2. Did not label the CDs to show clearly they would install XP
I want Vista Business back.
What can I do?
Message Edited by aldo on 06-16-2009 02:00 PM

Many thanks for the advice guys, it's illuminating but leaves me annoyed and unhappy.
I ordered a ThinkPad X61s factory loaded with Vista Business.
It was delivered together with one Rescue & Recovery CD, and six Product Recovery CDs.
The Product was Vista Business.
There was nothing stating the CDs would "downgrade" the Product to XP.
Why would I think to burn an additional set of recovery discs since Lenovo appeared to supply them?
It defies logic that Lenovo should consider those who order Vista but later wish to downgrade to XP, yet does not make clear the recovery discs are for that downgrade and not for Product Recovery which is what it says on the tin labels!
The problem was caused by the inclusion and mislabelling of the CDs as recovery discs - if they had not been supplied, or been clearly labelled as the downgrade to XP, then I would have burned the correct ones.
At least some colleagues with HP notebooks are supplied with TWO sets of recovery CDs, one for Vista, the other for XP.

SharePoint 2010 backup and restore to test SharePoint environment - testing Disaster recovery

We have a production SharePoint 2010 environment with one Web/App server and one SQL server.
We have a test SharePoint 2010 environment with one server (Sharepoint server and SQL server) and one AD (domain is different from prod environment).
Servers are Windows 2008 R2 and SQL 2008 R2.
Versions are the same on prod and test servers.
We need to setup a test environment with the exact setup as production - we want to try Disaster recovery.
We have performed backup of farm from PROD and we wanted to restore it on our new server in test environment.Backup completed successfully with no errors.
We have tried to restore the whole farm from that backup on test environment using Central administration, but we got message - restore failed with errors.
We choosed NEW CONFIGURATION option during restore, and we set new database names...
Some of the errors are:

Aborted due to error in another component.
Could you please help us to resolve these issues?

I'd totally agree with this. Full fledged functionality isn't the aim of DR, getting the functional parts of your platform back-up before too much time and money is lost.
Anything I can add would be a repeat of what Jesper has wisely said but I would very much encourage you to look at these two resources: -

Control file lost and datafile addeed restore/recovery with no data loss

Here i have tried to the following
created new table called t2 and made sure data went to a specific tablespace...
took a level 0 backup
removed the control file
added couple of datafile to above tablespace and then inserted more data
then went out to restore control file and the database...but datafile still could not be opened ?? what did i do wrong here....

Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function.

Database restore to test from production

Hi,
I am having 500+ GB database running in AIX with ASM. creating disk backups using rman and moving to Test server.. i like to know the commands for restore and recovery from disk to ASM in test server:
Prod server : ASM on AIX single instance
rman database backup to disk (SID : PROD)
ftp to test serverTest server: ASM on AIX single instance
clean up exiting database (SID : TEST)
rman restore and recover command from disk The rman command i am using for backup is :
run
allocate channel backup_disk1 type disk;
allocate channel backup_disk2 type disk;
allocate channel backup_disk3 type disk;
sql "ALTER SYSTEM ARCHIVE LOG CURRENT";
backup
format='<path>/Sml_full_bck_%Y%M%D_%d_%s_%p.dbf'
database
plus archivelog
filesperset=1;
backup
format='<path>/Tp_cntl_%Y%M%D_%d_%s_%p.ctl'
current controlfile;
#sql "alter system switch logfile";
release channel backup_disk1;
release channel backup_disk2;
release channel backup_disk3;
What would be ideal command for restore....

we have some issues with network....need to ftp manually after taking backup..i am looking around for the restore command like
run
allocate channel t1 type disk;
restore database from '/<path>' to '+DATA';
recover database;
release channel t1;
just want some clarifications on syntax especially from disk backup restore to ASM disk groups and recover from there..

SAP BW System - Memory requirement to restore to test server

Hi,
We have SAP BW system version Business Information Warehouse 3.0B. System has following configuration:
~
CPU : 32
Physical Memory: 67108864 KB
Physical Memory Available: 30654448 KB
Database using Memory: Apprx 20 GB
Database Size: Apprx 5.3 TB
~
We are planning to restore this system to a test server. Test server is having 4 CPU and 8 GB RAM.
Can you please let me know to do a restore, how many CPU and Minumum RAM We require on test server? How to check from current configuration, how much SAP is using memory?
Appreciate your help.
Thanks a ton in advance.
Best Regards,
Basis CK.

Hi Arun,
Thanks for the propmt reply.
We are just planning to do a Disaster Recovery Mock Run. We will be restoring production server database to test server and will be recovering a database and then will start SAP.
But not sure, if 4 CPU and 8 GB will allow to start SAP. Can you help? Currently Instance profile memory parameters has been set for 64 GB memory. I need to adjust the profile parameter propationately for the less CPU and memory ? how to check and do that.
Appreciate your help.
Thanks
Regards.
