How to do media recovery from cold backup?????????/

Hi
i take cold backup of my 9i database ....
in case my database is up .....
how will i recover my database if i lose a single database file and i want to recover it from cold backup......
Thanks in advance
Gagan

Here you go
These are the steps:
1. Restore the lost file from a backup.
2. If the database is down, mount it.
SVRMGR> STARTUP MOUNT PFILE=<location_of_pfile>;
3. Issue the following query:
SVRMGR> SELECT V1.GROUP#, MEMBER, SEQUENCE#,
FIRST_CHANGE#
FROM V$LOG V1, V$LOGFILE V2
WHERE V1.GROUP# = V2.GROUP# ;
This will list all your online redolog files and their respective
sequence and first change numbers.
4. If the database is in NOARCHIVELOG mode, issue the query:
SVRMGR> SELECT FILE#, CHANGE# FROM V$RECOVER_FILE;
If the CHANGE# is GREATER than the minimum FIRST_CHANGE# of your logs,
the datafile can be recovered. Just keep in mind that all the logs to
applied will be online logs, and move on to step 5.
If the CHANGE# is LESS than the minimum FIRST_CHANGE# of your logs, the
file cannot be recovered. Your options at this point would be to restore
the most recent full backup (and thus lose all changes to the database
since) or recreate the tablespace as explained in scenario a.
5. Recover the datafile:
SVRMGR> RECOVER DATAFILE '<full_path_file_name>'
6. Confirm each of the logs that you are prompted for until you receive the
message "Media recovery complete". If you are prompted for a non-existing
archived log, Oracle probably needs one or more of the online logs to
proceed with the recovery. Compare the sequence number referenced in the
ORA-280 message with the sequence numbers of your online logs. Then enter
the full path name of one of the members of the redo group whose sequence
number matches the one you are being asked for. Keep entering online logs
as requested until you receive the message "Media recovery complete"
7. If the database is at mount point, open it.

How to Create new database from cold backup files.

Dear Experts,
I have an oracle 10g databae on windows 2003 server.
The database is in Archive log mode and backup strategy is Taking cold backup ever night.
Backup steps:
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location.
Startup.
I have taken a backup at Tuesdaay 1AM and I have archive logs also.
On Wednesday, I want to Create a new database on another server with the available cold backup files and archive logs. I want to recover the database upto 4PM Wednesday. How can I do this.
I am not using control file auto backup or control file backup to trace.
Please help me how can I do this. I am new to oracle database Administration.
--Thanks

The steps :
shut down database.
copy data files, control files, redo logs, archive logs and parameter files to safe location -- you mean the alternate location for the new databaseare correct (except that I would say "alternate location for the new database").
If you do not have controlfile backups, you cannot either OPEN the database or RECOVER the database until and unless you CREATE the Controlfiles. You have to generate a CREATE CONTROLFILE script using a BACKUP CONTROLFILE TO TRACE from the Production serer and create the controlfile on the new server.
BEFORE the Startup, I would use
RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;The "using backup controlfile" tells Oracle to continue attempting Recovery -- ie doing a RollForward -- till the last archivelog made available to it.
For the Recover command, you then keep applying the ArchiveLogs from the Tuesday 1am ColdBackup upto Wednesday 4pm.
Once you have applied the last ArchiveLog, you do an
ALTER DATABASE OPEN RESETLOGS;Here are my notes of doing a RollForward "Recovery" from a Cold Backup :
http://hemantoracledba.blogspot.com/2007/05/rollforward-from-cold-backup.html
If you are attempting all these steps on a different server from your current Production database, you should be safe.
Once you OPEN the database, you can use CREATE CONTROLFILE or the NID utility to rename the database.
If you are attempting to create the new database on the same server there are many other precautions you have to take and unless you have experience with cloning databases, I would advice you against doing so (only the RMAN DUPLICATE DATABASE command has a safer method of cloning a database).

Enterprise Manager Configin a new host after recovery from cold backup

Dear friends ,
we have recovered a DB in new host(windows) from the cold backup.
Listener is configured and EM is also configured .
I am able to login through the EM . In the front page i get an error like
java.lang.exception:unknownhost exception sensding request ::<hostname>.<domain>
Please Note :The hostname from which we have taken backup(operation system) is different from the new host name where have recovered the DB.
Also when i clicked the link for administration page or performance page
i was taken to the login page which was showing as follows
user name:
password:
Connect String : <old host name>.<domain name>
Now i dont know where is parameter of old host details are stored and how it has to be replaced.
Please reply if anyone can have the solution .
Thanks in advance
Madhu

Please Note :The hostname from which we have taken backup(operation system) is different from the new host name where have recovered the DB
This is the call for trouble actually.EM repository stores the info of hostname/ipaddress of the machine where it is configured. So any change in that information will not let you use EM.There are couple of files which are there in which this information is stored and if needed, that information can be be manualy edited.But manual editing is not a good way to deal with repository.So the better option for you is to recreate the repository of your EM
Follow the link for the description of the commands.
You would have to use
$emca -deconfig dbcontrol db -repos drop
$emca -config dbcontrol db -repod createHTH

Recovery from cold backup

Hi,
We take Hot backup everyday, but I took a cold backup using the same catalog. If I want to restore the cold backup I took, what is the proceedure. We are running on 10g in HP Unix.
Thanks.

Hi Rock2,
If you want to restore the cold backup you need to know the tag belonging to this backup.
Using the logfile of the coldbackup or <list backup summary;> in rman you should be able to get this info.
The restore would be similar as:
connect catalog rman/pwd@define_rcv;
# check in catalog database for the dbid.
# If so set the appropriate dbid by unhashing the line directly below using the current dbid
# set dbid = define_dbid
connect target /;
STARTUP NOMOUNT;
run {
allocate channel tc1 type 'SBT_TAPE'; # or 'DISK'
allocate channel tc2 type 'SBT_TAPE'; # or 'DISK'
# adjust the TAG in the following lines
restore controlfile from tag TAG0000001;
sql 'alter database mount';
restore database from tag TAG0000001;
sql 'alter database open resetlogs';
release channel tc1;
release channel tc2;

Livecache recovery from cold backup with raw devspaces

We are recovering the Livecache database from code backup to a database with raw devspaces. We gave the following raw parameters to DATA and LOG devspaces:
DATA Devspace: /dev/vx/rdsk/azdevdg/lvlzddisk1
LOG Devspace: /dev/vx/rdsk/azdevdg/lvlzddisk3
We are getting the following errors during initialization:
2005-04-29 09:13:14 68 ERR 11000 devio read error (fd = 24): No such devic
e or address
2005-04-29 09:13:14 68 ERR 15 IOMan Unknown Data volume 1: Could not re
ad
Any Ideas ?

Hi,
as for all liveCache issues, I'd have to ask you too to open an OSS message on queue BC-DB-LVC.
A thing you could try:
try to read using 'dd' from your devices. If 'dd' can't read from the devspaces, then you've got a misconfiguration somewhere, i.e. an operating system issue and not a liveCache issue. In that case, we (BC-DB-LVC) wouldn't be responsible for the error.
The 'dd' command could look like:
dd if=/dev/vx/rdsk/azdevdg/lvlzddisk1 of=<filename> <blocksize>

Roland

Restore from cold backup (rac server)

Hi All,
Oracle version : 10g
OS : SunOS dixie1 5.10 Generic_118855-36 i86pc i386 i86pc
I am having cold backup of RAC server (2 nodes), I want to restore from cold backup.
The problem is that : when i performed the cold backup using rman at that time Oracle was having 3 ASM diskgroups.But unforunately that disk is no more in use due to some fault.
Now my question is how can i restore from the cold backup as when i'll restore from the cold backup this will ask for the same ASM diskgroups.Even more if i creates the same diskgroup with the same name and same configuration then my doubt is that rman will allow me to restore the same from the cold backup as ASM disk header changed now ?
Thanks,
Vipin

Yes.You can do these and restore/recover your database.First you need startup your ASM instance then create your ASM disk groups and do following:
1.Edit pfile and change controlfile location to diskgroup(Consder that +dgr1)
2.Restore controlfile to this disk group using backup of controlfiles(you say that is cold backup)
rman target /
/*Instance need starting up from pfile*/
startup nomount ;
/*then restore controlfile,give full path of controlfile from coldbackup*/
restore controlfile from 'coldbackup_location\coltrolfile';
alter database mount;
catalog start with 'coldbackup_location';
backup as copy database format '+dgr1';
switch database to copy;
alter database open;

Recover database from cold backup and add ol archivelogs....

Hello!
Scenarion : I have create in 1 january cold backup of my database. I have from 1 to 4 January all archive logs generated by my database. My database gone in 4 January.
Solution question : How can i restore database using cold backup a than add info from archivelogs to recovered database to do database consist from disaster day.

1. Kill current instance with SHUTDOWN ABORT.
2. Copy all control files and data files from your cold backup to original destination.
3. Make sure all archived redo logs from 01-JAN to 04-JAN are available in the database archive destination (LOG_ARCHIVE_DEST or LOG_ARCHIVE_DEST_x).
4. Run as SYSDBA:
startup mount
recover database using backup controlfile until cancel;When prompted for something like

Windows Server 2012 - Backup failing with Exchange - The application will not be available for recovery from this backup. the consistency check failed

Hi
We have a Windows 2012 server with Exchange 2013, all is working fine except now i am getting issues with the backup.
'Exchange - The application will not be available for recovery from this backup. the consistency check failed for the component Microsoft Exchange Server'
I have checked the database all is fine, i have created a new db and move all mailbox;s over and then removed the old db, i have enabled circular logging and then disabled it, it seems no matter what i do i cannot get a full backup!
i did have to restore the server once and the backups still worked for about 4 days after that and then stopped, i have also tried to remove and re add the backup role!
i am stumped, any advice would be great!

Hi
Ok, i created a test db and tried to back it up right away, it failed, i did not add any mailbox's to it either. i got quite a few events in the windows logs, as well as the same event above i got the following:

How do I transfer contacts from a backup to iPhone?

I just restored my iPhone as a new phone. I have a backup saved in my computer, not in iCloud. So my question is: how do I transfer contacts from that backup to my newly restored phone, and ONLY the contacts, nothing more (that's the whole point of my restoring my phone as a new phone).
I don't know if all of that makes sense, but if someone knows how to do that, please help me, I can't afford to lose those hundreds of contacts.

You cannot.
Why are you opposed to paying for some software to help do what you want?
You can restore the backup to your iPhone then sync the photos to your computer.

Database Restore from COLD Backup

Dear all,
I .m trying to restore a production database from a COLD backup. Before the COLD BAckup, we have take a HOT backup as usual and then shutdown the database to perform the Cold Backup.

Please do not confuse between the backup copies you have. Ensure that you have the latest copy whether cold or hot. If you have COLD copy then simply replace all the data files, redo log files, and the control files and start the database it should start. I do not understand your back up strategy because if you have a Hot backup then why do you need a cold backup. Please let me know in what mode your database is running?
