Cold backup -- have only _.BKP file in my hand (XE 11G)

I am trying to restore a backup (?????_.BKP) file that has been created on my Oracle XE 11g, and that is all I have in my hand - the database has been uninstalled and I have only the file.
Any one have the previous experience in recovering data like this?
Thanks,

No, I have no previous experience in recovering from an incomplete backup, as it is something which isn't possible.
If you don't have a RMAN catalog database, the control file functions as catalog.
If you don't have a separate controlfile backup and/or a RMAN autobackup of the controlfile of that database, your database is RIP.
Many people forget you make a backup to be able to restore and recover. And as they never test the restore and recover procedure, they run into unpleasant surprises.

A bash script to backup system only with modified files

Hi,
I've made a simple bash script to exam which files are modified and needed to be backed up.
It will use:
1. the hash in Pacman's database (/var/lib/pacman/local/<pkg_ver>/files
2. if no hash in the database, calculate it by our self from cache (/var/cache/pacman/pkg/<pkg_ver>.pkg.tar.gz
3. if no cache found, compare build date and last modified date
4. otherwise, this file better be backed up.
Currently it will only print which files are needed to be backed up, but no backup actually happens. (dry run)
And it is only in early development stage, please be careful.
USAGE:
<the script name> <where to backup files, a directory> <the files, or directories, separated by space, that are going to be examined>...

Thanks for this script. Nice work.
Can we traverse the pacman.log backwards up and rollback each operation (including "installed" in this). Something like:
history=$(tail -n +$(grep -m 1 -n "$1" "$LOG" | cut -d ":" -f 1) "$LOG" | tac | grep -E "(upgraded|installed)" | cut -d " " -f 3-)

Why do I have duplicates in my iTunes library when I have only a single file for each song on my PC?

I have duplicates for about half of the songs in my iTunes library. I've recently upgraded to a new PC so I'm assuming that it occurred at that point.
However, when I go in to my iTunes media files I only once copy of each album or song filed. Also if I search my PC I'm only finding one copy of each of these duplicated songs.
Duplicated songs appear to play equally well and there are no exclamation marks next to them either. I tried updating and that didn't work. If I uninstall and reinstall will it delete my iTunes media files? Will I need to back these up first?
Any advice on how to get iTunes to stop displaying the duplicates would be really appreciated.

Cold backup with online redo logs

I am working on 10G in AIX for a single instance
It is just a general db backup & restore question, but I have something confused.
I am going to perform a cold backup with my ARCHIVELOG database.
No wonder why I perform a cold backup because it is a testing database which can suffer from data lost and down time during backup.
I read some guides. They all mentioned to backup all the datafiles and control files.
During the restoration, I have to copy all the backed up datafiles and control files to the default location.
Then Startup mount;
The last step before open the database is recover database until cancel;
For the acknowledgement, I have to do the command of recover database, because the online redo logs were not backed up, thus we have to recover it in order to reset the redo logs.
For my question,Would I be able to skip the command of recover database, then directly startup the database if I have backed up the online redo logs and copy the default location during the restoration?
However, I read many documents which mention that it is not suggested to backup the online redo logs. Is it just the case which ONLY applied in hot backup? Do you all think that for my case, cold backup for online redo logs is recommended?
Thanks all

Edit: And never forget, those test databases are some developers production.Absolutely true according to my experience. Loosing the work of a payed developer is just as bad as loosing the work of a production system and may even be worse because it may not be possible to re-enter missing data into the system.
I think a cold backup is only suitable on special occasions, for instance, to relocate/copy the database to a different storage media, or if the database doesn't change or if loosing changes is absolutely irrelevant. Otherwise, put the database into archivelog mode and do a hot backup. After that you will also have alternative options which can make the restore and recovery of the database very easy and efficient, like flashback database, etc. but it will take substantial additional disk space.

Need clarification for cold backup and recovery

Hello Everyone ..
I have much confusion on cold backup and recovery topic.
Already i posted a scanario regarding this and i want to know some clarity points to understand.
1. I had cold backup two days before
2. I am creating an object *(EMP)* and inserting some records then issue log switch continiously.
3. Manually i removed all physical files (datafiles , control files , log files , redolog files ...)
4. then i issued STARTUP FORCE MOUNT;
5. here i am getting error identifying control file.
6. cold backup two days before all files restored
6. then i issue recover database using backup controlfile until cancel;
7. i am trying to issue select * from emp; i am getting error
select * from emp
*ERROR at line 1:
ORA-00942: table or view does not existMy QUESTION IS
After cold backup finished , i created emp table ..
when restoring old back " There is no emp table"
*- then , can i recover emp table ? - If so , please explain about this ..*
Note : REF - LINK https://forums.oracle.com/forums/message.jspa?messageID=11056341#11056341
- Above link says what i did ? . In this thread i am asking concept & logic ..
please do NOT consider as "*DUPLICATE*"

When you recover the database using backup controlfile until cancel, you have to apply archived logs. Did you apply all of them?
If the create command was in the online redo, not yet archived, and you lost the online redo, then you won't have it. This is why you want to have redo multiplexed, it is a critical piece.
In some recovery scenarios, if you haven't lost the online redo, you need to specify those files as if they were archives.
It is normally easier to just be sure you have the latest controlfiles and let Oracle figure it out automatically (which is why you want to use online RMAN backups rather than cold backups). But yes, it is important to understand what is going on for different scenarios. I used to have manual standbys, and one of the disaster instruction sets explained to try to get online redo over to the standby to lose as few transactions as possible. That could still be useful for some snapshot hardware type scenarios, assuming the business is too cheap to do proper failovers.

Is it "OK" to have a single .xml file that's identified by a specific app (Sound Studio)?

Since I'm have trouble in getting "Amazon's Cloud" to see my music files in iTunes, I'm wondering if the peculiarity I'm noticing with the .xml file in my iTunes folder is causing a problem. I have only one such file and alongside it is the green icon for my Sound Studio recording/editing app/program. When I trash the .xml file, it's replaced by the same green icon upon reopening iTunes, even though Sound Studio remains closed.
I'm wondering if Sound Studio might be prioritizing all other uses of iTunes. When I click on the .xml file, moreover, I'm told that Sound Studio cannot open files in the "Tab-delimited Text" format?

No, your answer is miles off. Our process needs to access the OVD LDAP in the normal way (its used for other things). The solution has to be within the borders outlined within my question. I want to add a "filter" java class somewhere (either in OBIEE, Weblogic or on the LDAP server) that converts my servlets encrypted passwords into plain text BEFORE the LDAP directory is read so that my OBIEE users can logon to OBIEE via my servlet.
As an alternative is there some way I can convert my Java servlet into a JAAS thingy that OBIEE will accept as a SSO source? Is that a possibility?
.....What about this......
1) I unpack the analytics.ear file
2) I add a servlet (jsp) in the root location that decrypts the NQPassword into plain text.
3) This servlet then FORWARDs (not REDIRECTs) to saw.dll passing the NQUser and NQPassword in plain text (I think forward is OK as it all stays on the server, the plain text password is not passed back to the client).
Would this work as a solution to my problem?

Restore database to another host - I have only rman backup files

Hi all,
The PC where Oracle was installed is crashed.
I have only the RMAN backup pieces in other computer.
I want to restore/recover this RMAN backup to other PC.
I know the commands, restore database, recover database,
but I've always used these commands with rman into existing rman
user. Now, I don't have anything. I have only the RMAN backup files.
How can I restore/recover database to other PC using these files?
The steps are? create other database, create a rman user, register
the rman backup files in this new rman, and restore these files
in this new database already created with the same name?
thank you!!!!

How to restore cold backup + archived log files

Hi,
Suppose I take a cold backup on 18th. After that I have four days of archived log files. if the database crashes on 5th day, I have to restore the 18th cold back + 4 days of archived log files. How do I restore since it is a cold backup and I cant do incomplete recovery.
can I use
Recover database ( with 18th cold backup) in mount state and apply archived logs.
Prabhath

The details of how you perform forward recovery using a cold backup depends on
1- rman or manual backup
2- using current or backup control file
3- if rman, recovery catalog or no recovery catalog
4- if full database recovered or only a few files
Each of these conditions will affect what is known to Oracle and what needs to be done. For example if you restored the entire cold backup including the control file then Oracle would see a consistent database and not need to perform recovery so you would need to startup mount and tell the database to perform recovery using a backup control file. If using rman and no recovery catalog you might need to catalog some of the archived redo logs, etc....
It is advisable to consult the Backup and Recovery manuals before attempting recovery for any new scenario.

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).

A question about restoring from cold backup(control file backup not clear)

Hi,
I had another question about restoring the cold backup. My database is in noarchivelog mode and after taking a consistent cold backup, all I need to do is to restore the backup right? -Why I got this question is because: when I backup my control file to trace, I see statements like this:-----
-- Commands to re-create incarnation table
-- Below log names MUST be changed to existing filenames on
-- disk. Any one log file from each branch can be used to
-- re-create incarnation records.
-- ALTER DATABASE REGISTER LOGFILE '/uo1/app1/arch1_1_647102958.dbf';
-- Recovery is required if any of the datafiles are restored backups,
-- or if the last shutdown was not normal or immediate.
RECOVER DATABASE
-- Database can now be opened normally.
ALTER DATABASE OPEN;
My database is in noarchivelog mode now so don't know why these statements (of register the logfile) is there in the backup of control file? so when I restore the cold backup of this database, it will still work correct? (there is no logfile I have only CRD files in cold backup -no archive log files.)
thanks

Build standby database using cold backup on a different file system & host

Hi gurus,
The database version is 11.2.0.3. OS is HP UX Itanium 11.31
I am building a standby database using cold backup of primary. The primary mount points are (/p003/oracle, /p004/oracle) on HOST1 and the standby file system on HOST2 are (/s003/oracle,/s004/oracle). I am not using Data Guard to apply logs as we have a script that mounts the log location periodically to standby server and apply the logs to make it current. I am using cold backup as the database is small like 200G and can be taken down. Could someone help me with the steps to build standby using cold backup for a different file location in standby ?? My concern is I can copy the data files from /p003 to /s003. How will I build the controlfile ?
If it was same File system on both HOST 1 and HOST2 I can copy the cold backup to the standby server, build a standby control file on primary and copy and replace the standby control file and everything was set.
Thanks

I backup to an external hdd with Time Machine, when it ran out of space it did not delete old backups, now my internal hdd says its full when before it had heaps of space. I have searched for extra files but cant find any. Can anyone help, please.

First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.
To locate large files, you can use Spotlight as described here. That method may not find large folders that contain a lot of small files.
You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

I have a huge 211GB <servername>.bkf file in a folder called exchangebkp on my C drive . I have only 1.5 GB free on that drive. I want to delete that backup file to make room, and know it has not been modified since july 2013, although
it seems to be accessed every hour or so .. What is that file? ntbackup has not been used on that exchange server. also, since i only have 1.5 free, will i be able to delete it?

Hi Mr. Multi,
I would like to verify if you have other Exchange backup at first.
If you don't have a full backup for Exchange data, it is not recommend to delete the .bkf file directly.

I currently have an iPhone 5, 16gb. I Do Not want to Loose any photos or albums by deleting them from my phone and not backing them up correctly. My iCloud backup is only storing my "Photo Stream" and I can not locate them in iTunes after I sync/Back up.

I currently have an iPhone 5, 16gb. My storage is almost full on my phone. There are only 80 mg available. I am new to icloud and also have always had trouble navigating around iTunes. (Even after endlessly reading through support and help topics as well as calling) My concern is about Not Losing any of my photos if I delete them from my phone. I have to delete a large portion of my camera roll as well as the Album Folders I have created. Although it would be great if there was a way to just keep my albums still. I have already backed them up to an external hard-drive, my computer and a geek stick. I'm not trying to be too paranoid about these photos, but, they are all of my 3 children. There are over 4000 pictures stored on my phone. Some photos go back as far as 2009. Can you offer any information about backing up my Camera Roll, not just "Photo Stream", and albums I've created On my phone? I read that it's good to back photos up on both iTunes as well as icloud. I even purchased extra icloud storage to back them all up. I do regularly back up/sync, my phone to my computers. However, I cannot even locate where they are stored on iTunes, let alone look at them. And as far as my iCloud backup, it only stores the new pictures from "Photo Stream". Please offer any advice you may have. I do not use up a lot of storage on my phone other than Photos and Contacts (it's a work phone). I would definitely be able to sleep better knowing my children can one day see these pictures of themselves. I appreciate your time. Thank you,

First of all, you should always save you photos on computer like any other digital camera.
Backup on iCloud or iTunes only backup your Camera Roll. The other photos should be already on the computer.
Note: Photos are not saved in iTunes, it's only a conduit between your iPhone and your photo managing software on computer.
What computer do you have?
