Yes, we can create standby control file, after backup.
What is your database version?
If you are using 11g version, then you can RMAN DUPLICATE command FROM ACTIVE DATABASE option.
This duplication is not backup-based duplication.

You have following options.

Add an additional operation mode Except for the duration of backup .
Example:

7:00 p.m. - 7:00 a.m. NIGHT (normal operation mode)
3:00 a.m. - 4:00 a.m. EXCEPT (Backup operation mode)
4:00 a.m. - 7:00 a.m. NIGHT (exception operation mode)
2.See if you get and error message in sm21 after offline backup.
3.delete the operation mode and create new .
4.try to change the timings of day and night operation mode.

Can't find folder created by Backup and Recovery app

Hi all,
I have A316i phone and when I select "Backup and Recovery" app and backup my SIM contacts it shows it created backup (and I can see it in the restore tab). But when I want to find that backup on my phone's SD memory card in order to copy it to my PC hard disk I can't seem to find it.
How do I copy backup folder from phone to PC ( and how do I find it)?
Thanks.
Solved!
Go to Solution.

Go to contacts > press the settings button (bottom left side)>Import/Export.
You can also export contacts to your google account... That way every time you change your Android phone just connect with your google account and all your contacts and the data (birthday, address, photo.. )you add to them will show up.

Create a standby controlfile using cold backup

Hi All,
We have to setup a DR for a production database.
Here we have the coldbackup which backups all the datafiles and the control file from the production database.
For cloining we generally copy them to another instance and then create controlfile manually. But for setting up as a DR , we would be creating it for standby controlfile.
I tried to google but I am not able to find a way to create a standby controlfile from the existing controlfile cold backup.
OS version solaris 10 , database version 11.2.0.1

How to create standby controlfile from restored backup

Hi Techies,
I am re-building one of my DR server, Source and target DB is oracle 10g.
I have taken the source backup which is going to be restored on target, But I forgot to take a standby controlfile from source DB at the time (Pre/Post) backup.
Now the issue is I can create a standby controlfile on primary and copy the same to target, But so many datafiles are added after the backup which I have taken to restore and medias are already shipped.
I can send the other set of backup to DR site, but it takes a week time and I don't want to do that If I can regenerate it.
So any clue to create standby controlfile on target with restored datafiles?
Regards,
Nick Loy

Hmm... sounds like you perform this in a rather manual fashion...
Do you use RMAN for taking the backups?
Or maybe the BR*TOOLS?
With these tools you are usually safe from such mistakes - I can only recommend to use them!
However, since you don't have a control file at all on the target side, the only thing left to do would be to
ALTER DATABASE BACKUP CONTROLFILE TO TRACE NORESETLOGS;
on the primary side and manually remove the files that have been added since you took the backup from the control file script,
Afterwards you use the script on the standby side to create the control files.

Lars

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.

ITunes creates corrupted backup after updating to iOS 8.3

So this happened right after I updated my iPhone 5s to iOS 8.3.
I got an "iTunes could not backup the iPhone because the backup was corrupt or not compatible with the iPhone" error.
I've followed instructions to update iTunes, restart the program, computer, and phone.
Delete backups.
I've tried backing up on my 2nd computer with the same exact error.
None of it works.
iTunes DOES make a backup. It says it was created 12/31/2000 at 6pm. However if I navigate to the folder in AppData it says it was created at the proper time on my computer's clock. I'm too afraid to restore that backup since my phone has no "real" backup now.
I would call Apple support but they want to charge me $30 for one session.
I've been avoiding restoring my phone because I don't want to spend the time to get all my apps and photos and music back onto the phone.
So I'm left with 2 options.
Restore the iPhone and waste a good hour of my time reinstalling everything.
Or waiting for the next 8.x iOS update and hope that fixes the issue.
Unless someone here can think of a 3rd option.

Hi there offroadguy,
It sounds like you’ve done quite a bit of troubleshooting to try and resolve the issue creating a backup of your iPhone 5s. If you haven't already, take a look at the article linked below which provides some additional troubleshooting tips that will likely resolve the issue.

Got error when creating a standby DB from rman: no backup or copy... Why?

We try to create standby database from a production DB on another server (10.2.0.4). The RMAN backup is in the nfs file system which is also mounted to the target server (the DR box). So, the access path for the rman backup is the same look from primary DB server and DR DB server. I started the RMAN run:

I have a free agent desk 500 GB external hard drive. Since updating my iMac OS to Mountain Lion it no longer backs up through Time Maching like it did in the past. Now, after completing its work it says, "Unable to complete backup. An error occurred while creating the backup folder." I cannot find any sites that help me fix this. Do I need to purchase a new external hard drive?

Please! can anyone tell me if after I create a site with adobe muse, is there anyway for my client t

Please! can anyone tell me if after I create a site with adobe muse, is there anyway for my client to edit and update text and to a lesser extent images on the website?
I don't care if the client text/image editing and updating doesn't update in my Adobe Muse, as long as my client can update the text online.
Please help me answer this question, I have used adobe for decades (2) and am a print designer. I want to use Muse for websites but if my clients can't update text and images, I don't see how I can make it work.
If I have to use Business Catalist too; I don't care. I just want to be able to use this great software.
Sorry if I soud desperate but I'm holding on starting a website for a new client and need to get this answered first.

At the moment you can't using Muse's widgets, though you can insert html! So, you could have photo galleries linked to flickr that the client can update to, for example. I'm sure there are other options for slicker slideshows that can be updated client side!
For text, I'm too much of a novice, unless you were wanting a blog style: http://www.muse-themes.com/blogs/news/7257782-creating-a-blog-in-adobe-muse-powered-by-nab ble
Basically, I think you need to find the right html to embed for your purposes

There has never been a legit way to downgrade.
It will always restore to the latest available software.

Can Anyone Tell Me Why Time Machine Won't Create A BackUp Folder for a Programed Backup?

Does anyone know why my Time Machine is NOT creating a backup folder on and regular scheduled backup? Just recently I downloaded the Time Machine Editor and it said to turn off the regular Time Machine (ON/OFF) switch, and just run off the TM Editor. However, at 1am in the morning, it comes up with the error saying it can't create a Backup Folder. I'm sure this is a simple solution but I really don't know how to handle this... Would appreciate any and all help in this matter... Thanks, Gary

Were you already backing up with Time Machine - ie, did you have an existing backup folder on the drive before you started using Time Machine Editor? If not, you probably need to do at least one full backup with TM, and then start using TME to schedule backups.

Yes, you can sync podcasts. Except in this case it's KEXP.org's song-a-day podcast that are just songs. I want them to work the same way as any song in my library from any other source. I do not want to manage them as podcasts. And for whatever reason it won't send them to my iphone as songs unless I right click and convert to mp3. And yes, they already are mp3s. Before I convert them, they don't ever show up in iTunes DJ or in Music either. I don't know... ask Apple.

HT1414 Some videos that are stored in iCloud remain on my iPad after backup.What can I do to store them in the cloud again?

After watching tv shows that were stored in iCloud, they remain on the iPad device even after backup is performed on iCloud.
This limits my iPad storage. How do I get them back to iCloud as soon as I have finished watching?

Backing up your iPad won't change what is stored on your iPad, and you can't put TV programmes into the cloud - they will only show there whilst the TV company has them for sale in your country's store.
How did you download them onto you iPad e.g. via the Purchased tab in the iTunes store app or syncing, or do you have videos in the cloud showing (Settings > iTunes & App Store > Videos 'on') and tapped on a cloud TV programme in the Videos app ? If the former then you should be able to delete them directly in the Videos app, either via the Edit button on the TV programme selection screen, or by selecting the series and swiping across the episode from right to left. If the latter then do they show in Settings > General > Usage > Videos (under the 'Storage' heading) ? If they do then you should be able to delete them by swiping across them from right to left.
