Restoring tigger from cold backup.

Hi
I have one problem..... recently i have drooped 1 trigger by mistake of one of my user in database. Now the problem is... we never take the logical backup of that DB.
Backup mechanism of the database is Cold Backup and size is *2TB*.
Now i have to restore that trigger from the cold backup with minimum effort , do i have to create the Clone database with the Cold backup using all the datafiles ...? or System tablespace ( or datafile) and default Schema tablespace(Schema which holds the trigger and its tables) in enough for restoring the trigger ?
I hope i am clear with my question. please let me know if you need more details.
Please suggest some best and fast way to solve this problem.
Thanks,

You need to restore enough to OPEN the DB can you please elaborate this clearly....
The version is :
Oracle Database 11g Release 11.1.0.7.0 - 64bit Production
PL/SQL Release 11.1.0.7.0 - Production
CORE 11.1.0.7.0 ; Production
TNS for Linux: Version 11.1.0.7.0 - Production
NLSRTL Version 11.1.0.7.0 - Production I have dropped in this Monday. Flashback is not implemented.

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;

RMAN Restore from cold backup ?

Hi ,
I am trying to restore the database from production db using the RMAN cold Backup. Both the prod and test(Restore database) are on the same machine. And also I wanted to have the restore db name should be different.
And the restore db name should be different. What are the options I have ?

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.

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.
Regards... Marcin

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

I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Mac

I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Machine, there are only about 5 backups recorded on the ext. hard drive. There were many more before. Any idea what happened and if I have to buy a new back up hard drive?

Hallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.

Music wont sync on my new iphone 4s. Restored it from a backup and now there's no music on it. In the music tab it says: Thomas iPhone has access to music on iCloud. Songs can be fetched via WIFI or a mobile network. What to do?

Restored it from a backup and now there's no music on it. In the music tab it iTunes says: Thomas iPhone has access to music on iCloud. Songs can be fetched via WIFI or a mobile network. The pnly thing I can chose to sync are voice memos.
What can I do?

If you want all the songs from an artist on your phone you can to to the artist view, tap on the artist, scroll to the bottom of the list and you will see a Download All button. This works for playlists and albums too (scroll to the bottom and tap the Download All button). I suppose if you wanted all your music on your phone you could create a smart playlist in iTunes on your computer that would contain all your music, upload it to iTunes match (Store>Update iTunes Match), and then you would get a Download All button at the bottom of this playlist on your phone to download all your songs.

Iphone4 would not restore Error -50. I have tried to restore and it restored it to the point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out.

Iphone would not restore---- Error -50. I have tried to restore, and it restored it to the new point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out. I can see earlier backups in my C:\Documents and Settings\user\Application Data\Apple Computer\MobileSync\Backup folder. There are four subfolders in this address. I need my contacts, photos, and messages back. I know this is a common error but I can not figure it out. I have ran the other troublshoot items in the error steps for 13 and 14 like apple says. Is there a way to call apple and get a step by step of how to restore from another restore point? Does anybody have a solution????

It tells you to go to Error 13 and 14 if you receive error (-50).
Here is what I have tried...
Error 13 and 14: These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting. I have moved it around to different ports.
Put a USB 2.0 hub between the device and the computer. Didn't change anything.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts. Removed all virus protection and firewall.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.Used the Microsoft fix it.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online. Doesn't matter.
Try to restore from another known-good computer and network. I do not know how to do this or how to find the correct/full/complete restore point. There should be more information for this.

I am not able to restore spfile from rman backup ;;;

Hi,
I would like to know few things
1. How are you setting the db_name ? you can set db_id at RMAN, how are you setting the db_name ?
2. Do you have any default init file at default location ? if yes, is the db_name parameter set correctly in that file ?
Since spfile is yet to be restored, you must set the db_name parameter correctly before you start spfile restore.This can be done with init file at default location which can even contain just one paremeter i.e db_name.

Help Restoring iPhone from iTunes Backup

My daughter was having problems with her iPhone 5. It was just acting strange, locking up and being weird. So I backed it up to iTunes and did a complete reset.
When I tried to restore from the backup, nothing. The restore seems to run fine for about 3-4 minutes, then the restore progress window just closes and the phone is disconnected from my iMac. No error messages are displayed anywhere - neither on the phone nor in iTunes.
I have tried this with 2 different OEM Apple cables, in 2 different USB ports, and even ensured that I had the latest iTunes (11.04, I did)... rebooted the iMac... tried the restore again.
The next step was to put the phone in DFU mode and do a new restore. Same results.
Anyone with any idea what is wrong? I would expect some sort of error message in the very least, but I’m getting nothing.
nothing works. She has lost photos, text messages, contacts (no iCloud backup) and game progress. And I am in deep doo-doo with my daughter.
Anyone with any idea what is wrong? I would expect some sort of error message in the very least, but I’m getting nothing.

If you have a backup on iCloud, wipe your device and when you activate it you will have the opportunity to restore again from that backup.
better yet, if you have a backup in iTunes it will go a LOT faster to restore from there.
Verizon cxl'd the iCloud restore because it can take hours and they certainly don't want you to wait around in their store.

My question is, How can I restore control file from tape backup without CONTROLFILE AUTOBACKUP setting ON.
It sounds like, There is no way we can restore control file from tape backup if you've not set the CONTROLFILE AUTOBACKUP is ON.
Please advice

When all controlfiles are lost and a recovery catalog is NOT used, RMAN has no information , where to find the controlfile backup. It's not enough to specify the channel, such a channel could hold many different backups from many different databases. You have tell , which database and which backupset. Modify your run block:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';

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).

Hard disk crashed, restored data from tape backup, Firefox not showing bookmarks. What is the location of bookmarks & favourites to ensure I have restored the correct file?

Hard disk crashed (XP), restored files from tape backup using Retrospect onto new Windows 7 laptop. Started up Mozilla after restore but bookmarks and favourites are missing.
I still have access to the backup tape and files. I was wondering whether the bookmarks are kept anywhere special other than the Mozilla program file that I restored.

Is it possible to restore DB from Obsolete backup?

Hi,
Is it possible to restore DB from Obsolete backup? If yes. How?
Thanks
Rajesh

Catalog your backup again to restore it. Please read the below paragraph.
Cataloging Older Files in the Recovery Catalog
If you have datafile copies, backup pieces or archive logs on disk, you can catalog them in the recovery catalog using the CATALOG command. When using a recovery catalog, cataloging older backups that have aged out of the control file lets RMAN use the older backups during restore operations. For example:
RMAN> CATALOG DATAFILECOPY '/disk1/old_datafiles/01_01_2003/users01.dbf';
RMAN> CATALOG ARCHIVELOG '/disk1/arch_logs/archive1_731.dbf',
'/disk1/arch_logs/archive1_732.dbf';
RMAN> CATALOG BACKUPPIECE '/disk1/backups/backup_820.bkp';
You can also catalog multiple backup files in a directory at once, using the CATALOG START WITH command, as shown in this example:
RMAN> CATALOG START WITH '/disk1/backups/';
RMAN lists the files to be added to the RMAN repository and prompts for confirmation before adding the backups.
Be careful when creating your prefix for CATALOG START WITH. RMAN scans all paths for all files on disk which begin with your specified prefix. The wrong prefix may include more files than you intend. For example, a group of directories /disk1/backups , /disk1/backups-year2003, /disk1/backupsets, and /disk1/backupsets/test and so on, all contain backup files. The command
RMAN> CATALOG START WITH '/disk1/backups';
catalogs all files in all of these directories, because /disk1/backups is a prefix for the paths for all of these directories. In order to catalog only backups in the /disk1/backups directory, the correct command would be:
RMAN> CATALOG START WITH '/disk1/backups/';
