RMAN RESTORE FROM TAPE DIRECTLY

Dear All,
We are in the process of testing the restore functionality of our production Db. The Backup is taken by Rman which is integrated with Netbackp. The backup files are directly going to the Tape storage.
Scenario
1. We need to restore the backup into a different host which doesn't have access to the Netbackup server and Production Db (Its a DR site)(DR excercise).
2. System team can provide the tape on the standby server.
Concerns
1. How can i proceed with restore in the secondary host.
2. Is there any way to read the backup pieces from Tape and catalog it using rman
If any come across this scenario, kindly share me the solution.
Thanks in Advance

If it is a NETBACKUP device, you can't restore without NETBACKUP. Well, there have been articles written on howto, but they all seem to end in "I just installed netbackup, imported the tape and restored from there."
I NEVER, EVER backup directly to tape - always to disk - most frequently with enough space to store 2 full backups plus enough archivelog file space to span before and after those backups, then sweep the backup location to tape. Recovering from tape can take 50-150% longer. If you use NETBACKUP, install it where it is needed. Going "cheap" could potentially cost the company more in downtime, than the licenses would have costs. If you NEED data, you NEED licenses to run the tools required to recover from a disaster.
The sad part is that should a catastrophic failure occur, it is usually at the most inopportune time.
Companies should treat their data [required to run their business] with the same security and backup strategies as if it was cash in the bank. I have seen a very large company literally throw away over $8M in unrecoverable orders due to impatience with bringing a system back online and not allowing the proper recovery processes to occur. Not having the proper licenses would fall into this category. Can your company afford to lose $8M in income?
Sounds like your company really needs a Business Continuity Review of your DR processes and procedures.

RMAN Restore from tape

Hi,
I have weekly full and daily archived RMAN backup directory to tape. I want to do clone on another server. I have all information HANDLE , TAG etc. What is the best way to restore to another server and clone database. Do I need to restore tape contents to disk and clone?
Thanks

1)Using DUPLICATE TARGET DATABASE command
sample :
On clonedb do following:
rman target <targetconnectiondetails> catalog <catalogdbdetails> auxiliary /
run
allocate channel ch1 <copy the channel allocation command from source database >
set until database to_time('till what time you need data')
duplicate target database to 'clonedbname'
2)From 11g you can use ACTIVE DATABASE DUPLICATE. which does not rely on backups

RMAN Backup Restore from tape

Hello Gurus
We have lvl0 RMAN database backup restored from tape but due to some reasons we could not apply recovery on it. On checking the information in controlfile, it identified only the system file and no other file. So, we recreated the controlfile and decided to recover using backup controlfile option (until cancel or until change or until time). However, to my surprise, when I listed the checkpointchange# and checkpoint_time columns of v$datafile_header, I found the difference in timestamps ranging 24 hrs -- which menat we had to apply 24 hrs of archiving to bring all dbfs to a consistent state (before it allowed us to open the db) -- so far so good, it worked that way.
My question is that, while I trigger a lvl0 RMAN backup at say 4PM on 27th July and it finishes on 4PM on 28th July (as I am directly pushing around 1 TB data to tapes) -- what is the consistency timestamp of this backup. In other words, is this backup available for a restore of 4PM 27th July? Or is it available only for a restore of 4PM 28th July and later ...?
Isn't it that RMAN works at block level and when I fire a backup it should give me all the dbf's of that timestamp..?
Appreciate your inputs/comments.

When taking a online backup with RMAN, the datafiles backup is always inconsistent because it needs the archived redo logs generated during the backup to be consistent: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/intro005.htm#sthref70.
A full online backup can only be used to restore the database to a point in time starting after backup end: if a backup starts at 4PM on 27th July and it finishes on 4PM on 28th July you can use it to restore the database to a point in time after 28-JUL 4PM.

RMAN restore from monthly tape backup

hello!
i have one more question regarding rman and tape backups: we don't want to store the rman recovery information in a separate database, so all the information is in the control files. but for revision we need to save one full backup per month. in addition to the databases we need files from different servers etc. on this tape-backups. so we decided to keep one tape set per month in a safe place -> is it possible to restore a rman backup from this tapes, e.g. 3 years afterwards (on a different machine)? thanks.
bye,
christian

Hi christian,
Can you give more info?
As I understand it you do not want to use a recovery catalog ("we don't want to store the rman recovery information in a separate database").
But if you store the rman backup info in the controlfile only you will limit the amount of rman information to your init parameter control_file_record_keep_time.
Do you make rman backups to tape directly using a MML or do you make rman backups to disk which than get copied to tape (OS backup)?

Tycho

Restore from tape speed check

Restore from tape : how we can find out out restore speed in MBs? and how to check if there are any bottlenecks/slow speed and what are things to adjust to increase its speed.

Hi DBA2008,
With rman the backup of only the data will be transfered to tape so an almost empty 2g datafile will be faster than a full 2g datafile.
To actually measure the speed you should time a backup to tape and with <list backup;> get information about the amount of data transfered.
Than time the restore this will give you an idea.
Depending on your hardware allocating more channels in the rman command can improve performance.
You could also check the backup system documentation for helpful information to measure/improve the speed.

Tycho

RMAN restore from alternate location

Hi:
Have anybody tried that - running rman restore from an alternate location?
I mean when the server location specified in backup script is lost (but you have your backups on tape).
Or one just needs to recreate identical location?

Hi Greg,
1. Copy the backupset/backuppices to /db1/backup/MYDB
2. If the database is in archivelog mode, and u have the current controlfile use it.if not use the backup controlfile.
3. mount the db.
4. connect to rman
RMAN> catalog backuppieces 'db1/backup/MYDB/bkpiece_name';
Do it for all the backup pieces...If suppose u have 5 backuppieces then write the above command for all the 5 pieces replacing the bkpiece_name.
5. run the restore database command on rman prompt.
6. Apply archives manually/ or if are present in the same loaction u can do with rman.
Regards,
Anand

RMAN restore from active database, ASM

I'm attempting to refresh a stage database from a prod database using RMAN restore from active database. Both are on ASM. After working through various hurdles, I've got one issue I'm a bit stuck on. I've got a handful of data files that do NOT have OMF names (ie MSTRDATA/mstrmdpd/datafile/gsa_indx instead of MSTRDATA/mstrmdpd/datafile/gsa_indx.351.714779777) and these are failing when I do the restore. The syntax I'm using in RMAN is as follows:
duplicate target database to dwstage
from active database
spfile parameter_value_convert 'dwprod','dwstage'
SET DB_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE'
SET LOG_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE';
The error message I'm getting is this:
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 04/21/2011 13:26:24
ORA-17628: Oracle error 19505 returned by remote Oracle server
continuing other job steps, job failed will not be re-run
Normally from what I've seen/read this error can be traced back to needing to pre-create the directories for the controlfiles etc, but since 90% of the datafiles copied correctly...
Any suggestions as to a way around this, or am I going to be forced to restore from a backupset?

This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.
Could you please help me on how to proceed?
One option can be to create the controlfile manually and mount the instance before doing the duplicate. I hope Rman can continue from there.
Another option is to go for backup based duplicate.
Is there any other way to go?
Provide static registration on AUXILIARY side for your auxiliary instance and try again.For example change listener.ora file as
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = AUXDB)
      (ORACLE_HOME = <your oracle home>)
      (SID_NAME = AUXDB)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = <auxiliary host/ip>)(PORT = 1521))
)And restart listener on auxiliary host then try again

How to restore a Rman backup from Tape

Hi,
We need to restore the database backup taken through RMAN on 24-JUNE-2013 from tape as this backup is not currently available on disk.
Can you please help me on the following,
1) how i can check if the same backup on 24-JUNE-2013 is available on Tape.
2) If yes how i can restore to Disk.
Because we need to create a new Clone instance from the backup taken on 24-JUNE-2013.
We are having 12.1.3 Application on Exalogic and 11.2.0.3 Database on Exadata machine.
Our support is highly appreciated.
Thanks

Restore RMAN backup from tape

I have to restore the RMAN full backup from tape to new host to a previous date say March 1st. My target database RMAN retention period is 28 days, today is 11th May.
Is it possible to restore the obsolete database from tape backup to new host as of May 1st. If not possible, I would like to restore the available backup say as 15th April from tape to new host.
Can you please provide me the steps to restore the tape old backup to new host.
Thanks,
Mahi

Restoring RMAN backup from tape beyond retention policy ??

Hello Friends,
I just stuck in some basic finding. Need your help to resolve the questions.
How we can use RMAN backup to restore oracle database when the RMAN backup pushed to tape already and being a OLD backup ( before retention policy date).
Just to elaborate a more.. Say my retention policy is 3 days. I want to restore from a old backup like 30 days old.
So surely the requesting backup is behind retention date and has been pushed to tape.
Please suggest.
Thanks in advance.
Regards
Sinha.

Assuming the actual backup files still exist (the only thing actually deleted is the record of them in the catalog), you can make those files available and use the rman 'catalog' command to re-catalog them.

RMAN recovery from tape and disk?

Hey Guys,
Here is my scenario: -
I have Oracle 10g and I am using RMAN to backup to disk and then I use Networker to backup on tapes from disk (retention is set to 30 days on tapes). On RMAN - my retention policy is set to recovery window of 5 days after which it deletes the obsolete backup from disk and updates the control file.
My Questions:
1. If I have to recover any datafile or tablespace 20 days ago how can I restore it on Production. Since I am also backing up control files on tapes but my current control file will not have 20 days old information. Is there any way that I can restore my old backup?
2.How can I test my tape backup which is older than 5 days. In other words how can I restore my database from tape on another server/
Please suggest.

If you need to restore the whole database to a point in time that is 20 days old, you "only" need:
1. to identify the right control file backup
2. restore this control file backup with Networker
3. start the instance in mount mode
4. list required datafiles and archived redo logs backup sets listed in this control file with LIST BACKUP
5. restore these backup sets with Networker
6. restore and recover database with RMAN with the right SET UNTIL clause.
If you need to restore only 1 tablespace, that's Tablespace Point In Time Recovery (TSPITR) and is another story.
I don't think you can only restore 1 datafile that is 20 days old and leave other datafiles up-to-date (unless there is only 1 datafile in the tablespace and in this case this is TSPITR).

Speed up restore from tape

The restore from the tape runs always slow and use only one channel everytime. Is there any way we can speed up the restore using parallellism. Please suggest.
FYI - We are not using the RMAN catalog.

Hi Boochi,
Could someone let me know how to run duplicate target database command with degree of parallelism?.Open more channels of both types:
allocate channel tc1;
allocate auxiliary channel ac1;
allocate channel tc2 ;
allocate auxiliary channel ac2 ;
Or if you are using tape channels:
allocate channel tc1 type 'SBT_TAPE';
allocate auxiliary channel ac1 type 'SBT_TAPE';
allocate channel tc2 type 'SBT_TAPE';
allocate auxiliary channel ac2 type 'SBT_TAPE';
Rgds,

RMAN Restoration from MML

Hi All,
We have configured MML and uses RMAN to backup database using specified channels. Control file and SPfile backup also goes at tape.
Now my question is if we want to recover our backup or prepare a new instace with that backup, how can we restore our parameter file
from Tape and startup the Instance. Also how can we restore the control file backup. Kindly note that we are using control file as backup
repository not the Recovery Catalog.
Regards,
Abbasi.

Abbasi,
I wonder why you never consult documentation prior to visiting this forum.
You would definitely have found the answer.
As you also forgot to specify your database version, I can not act as a free lookup service for you.
Can you please inform me when you are going to stop your ongoing abuse of this forum?
Thank you in advance.
Others: please do not respond to this question, encouraging Abbasi to remain lazy and to continue his abuse.
