Identify L1 backup pieces and restore the latest control file

DB version:11.2
Platform : Solaris 11
We dropped a Development DB last month. But we kept the Level0 and Level1 rman backups plus the archive logs generated after the last L1 .
Our L0 and L1's were scheduled with a 4 day gap.
Now the dev team wants this DB to be restored in a different machine. We hadn't stored rman metadata in a catalog schema. All we have is the below backup pieces.
stcdev_p4lor85q_1_1.bkp
stcdev_yls3gkjl_3_7.bkp
stcdev_mhfr8293_5_4.bkp
stcdev_ipxsr8293_5_4.bkp
.I don't know which of the backup pieces are from L1 and which ones are from L0. If I manage to restore the latest control file from the latest L1 backup , then things will be easy. What if I mistakenly restore the old control file from L0 which doesn't have any info on any new datafiles/tempfiles I've added after that L0.
What would you guys do for situation like this?

After you restore the controlfile, simply ALTER DATABASE MOUNT and then issue a LIST BACKUP. That listing will show you what the controlfile is aware of --- if it shows both L0 and L1 backups, you can use it. If it shows only the L0 backup, try restoring the "other" controlfile.
If you can see the timestamps of the backuppieces, that would help you identify which is the "later" backup.

How do i reinstall lr5 and restore the backup catalogues. Also preset folder,preferences, preview

Recently, i had to do a clean re-install of windows 7hp. And also i saved the needed data. of course i lost all of my downloaded software etc. Their is a second drive on my computer with lightroom;its backups and a folder entitled all my photos. The same material for lightroom is backed up to an external hard drive. How do i go about re-installing lr5 , and restore the catalogue back ups and the other folders.? I need a step by step set of procedures here as i am a computer stupie. Thanks for your help!

Step 3. After the catalogue restore is done, will this leave this cat. folder in the same disk under lightroom or will this folder be deleted. I have all of the lightroom folders backed up on an external hard drive. Last step is to move all my pictures from the all my photos folder to lightrm. Is this correct? How is this done? By an import in the lightroom software using import,move.or copy on the top import toolbar. I know i sound paranoid on doing these procedures correctly as i do not wish to lose any catalogues etc.. Thanks for your help!!
Not sure where you came up with these steps from
Step 1 ... either should work, but the download is the most recent version
Step 2 ... double-click on the latest catalog backup, yes
Step 3 ... Catalog is whereever you double-clicked on the backup file, you can move it whereever you want thereafter, using your operating system with Lightroom closed
Step 4 ... no moving of photos should be needed, definitely NO IMPORTING NO IMPORTING NO IMPORTING NO IMPORTING NO IMPORTING, if the photos are not linked in Lightroom, then follow these instructions http://www.computer-darkroom.com/lr2_find_folder/find-folder.htm and remember NO IMPORTING NO IMPORTING NO IMPORTING NO IMPORTING NO IMPORTING and did I mention that you should not import your photos?
For future reference, you stated that you had Lightroom and its backups on the same drive ... do not do this ... backups must go on a different physical drive

Trying to restore after getting a new hard drive. I can see the backup on the Time Capsule and on the correct date but it is Greyed out. That is it wont let me open it and restore the machine. Have tried also Migration Assistant, no luck.

At startup hold down the Command+Option/Alt+r keys until you see a globe on the screen. Then use disk utility to partition and format the drive HSF+ and then select Reinstall Mac OS X. whatever version of OS X that originally came on your system will be installed and then you can upgrade back to Mavericks.

Now, I understand how the backup and restore the backup features function. However, if I don't want to transfer the music that I have on iTunes to my phone, how do I avoid it? How do I not transfer the music or take it out of my iPhone if it is already there? I really do not want any music on my iPhone because I have an iPod for that. Thanks. Hope someone can help.

When you connect your phone and start iTunes on the left side you will see your phone listed under devices.Click on te icon next to it that looks like a battery. Click on the music button at the top and uncheck the sync music box.

I upgraded to the new IOS, but lost data and apps. When I try and restore the only backup I see is the one made AFTER the lost data. How can I access an older backup from the cloud?

Why don't you talk to apple and find out if backup exists? That conversation with apple will stop your guessing.

Can I delete a later backup and keep the latest one as to not eat up all my space?

Are you talking about Time Machine backups on a Time Capsule?
It is fine to delete the backup as long as you are sure there is nothing you want.. and do a new clean backup. That will be the least possible space usage for a working backup.. Never delete files out of an existing backup.. it is very hard to manually delete files in the backup.
We do not recommend it.

If I back up my iOS devices on my iMac in the US, then do a time machine backup to an external HD, will I be able to plug the external HD into a brand new iMac in the UK and restore the new machine as per the old one, and restore my iOS devices?

Since you don't really have a question, I will give you a very broad information source for the next time you have a Time Machine question.

Oh, you cannot use a computer whose only disk drive is the target of a an OS X cloning operation regardless of what software is used for the clone. You can, however, use the source drive except if you try to clone using Disk Utility.

How can I restore the latest BIOS version when it doesn't appear in "Software & Drivers" page ?

When delivered, my brand new Pavilion desktop model 500-282ef was equipped with BIOS version 8014.
On the EFI\HP\Bios partition, only the \Current directory contained another version of the BIOS, an older one, namely version 8013. The \Previous and \New directories were both empty.
Experimenting with my new BIOS, I've unadvertently downgraded my BIOS version 8014 to version 8013.
Now, as you've probably guessed, I would like to restore the latest version
The EFI partition doesn't contain any installer to restore my BIOS to its former up to date version.
Unfortunately, "the drivers and update" page on HP support site does not provide any installer either.
I would be so grateful if some of the nice people here would ask HP to point me to such (probably unreleased) updater which should obviously exist.
I have saved a copy of my second Pavilion desktop BIOS using safawin.exe in the hope I could use it to achieve a restore. But I've been unable to use it to restore the latest BIOS as the restore process also requires a signature file.
Thank you very much for your help!

Yes Dave, that's what I meant: during the "downgrade" from BIOS version 8013 to version 8014, no BIOS backup files were created and I couldn't found anything in any directory of the EFI partition.
In an attempt to solve the problem, I have put manually a copy of the BIOS (v 8014) from my second Pavilion Desktop (same model, same age) in the "\New" directory. That BIOS file was created with the safuwin.exe utility.
That has been a nice step forward: Now, from the Boot page, the Firmware Management offers me the update option ("You will update from 8013 to 8014, OK?") but when I try to so, I got a error message saying that a signature file should also be present along with the BIOS file to flash.
In the EFI\HP\BiosUpdate directory I do see some signature files like HpBiosUpdate.s14 and HpBiosUpdate32.s14 which could be the signature files I need, but I have no idea about how to use them (or maybe rename them?) to allow the procedure to complete successfully.
Concerning the warranty, do you suggest I should invoke it ? Could you please clarify ? Actually my PC has no other problem than this BIOS "downgrade".
I trust that HP has in store all the files I need, which have probably been used when configuring my PC in the factory. My problem is to have these files available in the "Software & Drivers" page on HP site...
Thank you very much for your help. I stay tuned

You have made changes to your photo library using a newer version of iPhoto. Do you want to quit and use the latest version of iPhoto, or do you want to create a new photo library?

Long story short, I made a backup using TimeMachine of my iMac. I got my MBA which was being repaired and i restored from backup. Everything works fine, except for iPhoto which is not saying:
"You have made changes to your photo library using a newer version of iPhoto. Do you want to quit and use the latest version of iPhoto, or do you want to create a new photo library?"
I have OS X 10.7.2 and iPhoto 9.1.4. I've tried:
Repairing permissions
Deleting iPhoto, installing agaian, and updating
Repaired iPhoto Library (stays stuck at 98% when rebuilding database)
I've also tried iPhoto Library manager which cannot even see the library
Tried restoring from backup from iPhoto and it messed up library (I still had my backup)
Quite frustrating - any ideas on how to get iPhoto back to life?

Dunno why Software update was not displaying the latest version of iPhoto (9.2.1 as of January 27, 2012)...updating to this has fixed the issue

Backing Up and Restoring the Message Store v.s. the queue

Hello,
We are running iPlanet 5.2 Messaging Server and need to migrate to another (duplicate) 5.2 Messaging Server. We have all the software installed and the LDAP user accounts created. Now we just need to move the existing mail from one server to the other.
I found the Backing Up and Restoring the Message Store section in the Admin Guide says to back up and restore your data, Messaging Server provides the imsbackup and imsrestore utilities.
However I am wondering about the Queue?
Under <instance>/imta/queue
What is the difference between the Message Store
and the Queue? Can I just backup and restore the Queue using tar or cpio?
Thanks in advance for any advice.
Regards,
Tim

What is the difference between the Message Store
and the Queue? The Message Store is where messages get delivered to, so you can read them.'
The queue is where messages are temporarily stored, pending delivery to wherever they go.
You can use tar, cpio, or what have you for the queue. Stop the server first. . .
You then just restore the files to the new server. No need to restart or anything like that. Just dump the files in, and run
imsimta cache -sync
to tell the MTA to re-read the queue.
Can I just backup and restore the
Queue using tar or cpio?

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

My computer running Windows 8.1 no longer recognizes my 7th Generation Ipod Nano. I have removed and reinstalled the latest ITunes software and it still doesn't recognize my Ipod.

I previously installed my Ipod Nano 7th generation in Itunes, Windows 8.1. When I have recently connected, Itunes does not recognize it. I removed and reinstalled the latest Itunes software, but no success. Message says that Itunes sees an Ipod is connected, but does not recognize it. The USB connection is working fine, as I recharged the Ipod without problem.
