lost control file and datafile addeed restore/recovery without loss of data

Here, I tried the following

created a new table called t2 and made sure the data went to a specific tablespace...
has taken a level 0 backup
remove the control file
couple of datafile to above tablespace was added and then insert more data
then went out to restore the database... but datafile and control file always could not be open? What is wrong here...

You seem to have:
(a) old version of data through rman backup files
(b) old version of the control file
(c) Backed archived redo logs
(d) recovery archived logs that have been recently generated
(e) current online redo logs

Therefore, you should be able to bring back the database in the State wherever it was when you made the abandonment.
I don't do enough laps to be able to cite details on the commands to use (and I often find myself using the command line recovery after that file of rman restore, but the steps you need must be)

Take a copy of security of the data current, archived and online redo log files.
Restore the backup control file, data files, and archived recovery logs
Recover the database by using up to cancel backup control file
You have to do 'create datafile' bit as the collection hits the 'missing file' bit
You will need to provide the names of the archived and log files online redo recovery reached their
(although, presumably, you could leave copies of the logs stored in the default location)

How can I get my iPod Touch on the way of recovery without loss of data?

Hello

My iPod touch 4th generation shows a cable Apple USB pointing towards the iTunes logo.

I have not jailbroken it or fallen to set the mode of recovery, and when I open iTunes it comes up with the message saying that it has detected an iPod in recovery mode and I can't use it with iTunes unless I restore my iPod.

Of course, I don't want to erase all the 50 GB of music I stored on I have not saved recently.

Is it possible for me to get my iPod out of the recovery mode without restore me or lose my data?

Thank you very much

Control files and backup spfile

Hi all
This is a database of GR 11, 2. There is a running script to keep the full backup.
```
crosscheck archivelog all;
crosscheck backup;
backup database;
backup archivelog all delete input;
delete noprompt obsolete;
```
I checked the controlfile autobackup using - show controlfile autobackup. and it is turned OFF
But when I run - list backup of controlfile; list backup of spfile;
I find that contolfile benefits from the support upwards and also through the above script spfile
Can someone please explain to me how this happens without controlfile autobackup
Thanks in advance

This is a normal behavior on version 11.2 and beyond

No matter if controlfile autobackup turned OFF, RMAN automatically includes the control file and the server settings file in the backups of data file1

(i.e backup database command always include datafile 1 which trigger backup of control and spfile).

Deleted file recovery can recover incomplete files, i.e. the part of these files may be missing. Recover deleted files is much more reliable if recovery of a backup, instead of using recovery software.

These things depend on the operating system and the file system.

One thing, you can see: open one of these files damaged with a text editor, and then make sure that the constant % PDF is somewhere in the first 1024 bytes.

Toshiba satellite which is stuck in the installation of service Pack 1. I have service pack 2, can not fix with this cd, can I install service Pack 2 on it without loss of data or files?

I have the laptop (Toshiba satellite) friend who's stuck in the installation of the service Pack 1. I have service pack 2 and am wondering, since I can't fix with this cd, can I install service Pack 2 on it without loss of data or files?

PC claims service pack1 cd with file asms

When you use service pack 2 cd can not load product catalogues, it is fatal error, the Setup logs files should contain more information.

Why not integrate Service Pack 2 and Service Pack 3 on her XP CD by following the instructions here (using another PC):

http://en.community.Dell.com/support-forums/software-OS/w/microsoft_os/1443.aspx

Copy all data on an external hard drive, do a clean install using the XP CD updated (preferably on the BIOs)

Then, install the drivers from the system, then Microsoft Security Essentials, Windows 7 Firewall Control (XP free Version) and Malwarebytes' AntiMalware (free or Pro) or whatever you prefer security.

Then copy the files over.

This will probably lead to the best performance.

Incompatible control file and the data after the backup files
The company that I work has servers where some components are new more, so have a backup in the event of hardware failure. If we intend to do some clones of 1:1 of the current servers to change them in case of emergency. As most of the necessary data is not volatile and we reset stuff in any case, there is no need of replicaton, replace an old version of the database works very well. Now we could not easily get substitutes for our old material, so we had to set up new machines. And that's where my trouble starts, because now I had to actually set up the system and the database rather than do a simple copy of byte to byte. I'm mainly a programmer, using Oracle of 'other' side, but as our DBA is yet to come and the work must be done now...

So I did some reasearch and decided to do a normal backup of the cold. I have dumped the controlfile, copied data and configuration files to the new server and read the prompt SQL (no mistake there) control file. After some initial hiccups with the system (memory, etc.), I was finally about to start the database, only to get an error ORA-01190 ("1 database or control file is from before the last RESETLOGS").

I guess I did is a bad thing when you restart the database (used the wrong part of the control file) or when the copy of the data. The original data have split two readers for simplicity and logical, I copied their entire contents. So maybe I don't not copied to little but too?

As I said in the introductory paragraph, I'm not a DBA, but I'm willing to learn and listen. I don't expect a complete solution, but some guidelines when to look and what to avoid. Any help on this would be appreciated.
Currently, there are some points need clarification,

1. you don't need to re-create the control file, if you have a clean shutdown database and copied all the files at the same time (data files, control files etc.)

2. If you stop DB, copied files of data but do not copy the control at shutdown file, you must re-create the control file.

3. the error ORA-19909 suggested you resetlog prior to recovery.

ORA-19909: string data file belongs to an orphan incarnation
Cause: The data file specified has been restored from a backup that was taken during a period of time that has already been abandoned by a resetlogs operation or Oracle cannot identify what incarnation of database file belongs. The alert log contains more information.
Action: Restore a backup of this file that belongs to the current or a previous incarnation of the database. If you use RMAN to restore, RMAN automatically selects a good backup.

4. it would be better that again follow you from scratch the article.

for example,.

Copy the files you did copy over the data base to the bottom of the old server,
modify the control file creation script

RECOVER DATABASE USING BACKUP CONTROLFILE;
ALTER DATABASE OPEN RESETLOGS;

Control files and uir version

Hi all

What are your methods to keep the files under version control, namely SVN UIR? It works very well as binary files, but if someone makes a minor change to the user interface, there is no way that you can find it visually.

I tested the TUI under SVN files and in fact a quick 'diff' shows you what is new or changed in the file. It is possible to load files TUI with LoadPanel(), but it is not possible to have the default editor UI savings as TUI, making it impassable. So, how do you do that? A think a simple solution of NOR would be to have the default option of the editor as TUI, bearing in mind that in the past, there were several cases of .tui behave differently from .uir.

If some of you are in agreement, I'll drop a suggestion.

While you cannot Editor Save only in. TUI format, you can configure it to automatically generate the. TUI when you save the file: can it be a solution tailored to your needs?

In addition, even if I do not use version control, I honor your valuable suggestion and I'll congratulations your idea when you publish.

After that I did Disk Defragmenter to C I lost my files and setting up wireless for my windows

After I did Disk Defragmenter to C I lost some information and files for my windows then my wireless does not detect all wireless networks its lost all the operating parameters of my adapter wireless (Atheros AR5005G Wireless Network Adapter) I need to get files and setting of cos its all lost and I couldn't update my antivirus (Microsoft Security Essentials) 0 x 80240022

Hi jtm 8888.

Try these methods in the order shown:

Method 1: As a first step, update the network adapter driver by visiting the manufacturer's Web site.

You can also follow this step to do the same thing:

a. right click on my computer, click Manage, then Device Manager.

b. double-click the type of device you want to update or change.

c. right click on the device driver specific, you want to update or change.

d. click set to update driver to open the Hardware Update Wizard. Follow the instructions in the wizard.

For more information, see:

How to manage devices in Windows XP

Method 2: Follow the steps listed in this article and check if this may help you:

How to troubleshoot wireless network connections in Windows XP Service Pack 2

Note: The steps listed in this article are applicable to the other version of Windows XP as well service packs.

Method 3: For problems with Microsoft Security Essentials, see:

Running Exchange Server application of hotfixes and service pack to the server mailbox without loss of data during the restore?

People,
I would like to know how can I safely ask the Exchange Server service pack or cumulative update for the server role mailbox (no DAG) without loss of e-mail during the downtime and roll back the snapshot?
If I can do the following:
1. stop all Exchange Server services.
2. unplug the vNIC on the mailbox server
3 take a snapshot of the virtual machine
4. apply the service Pack of Exchange Server / Cumulative Update or Windows Update
5 reset
6 reconnect the vNIC, if the server online with no problem, commit / remove the snapshot, if not, then disconnect the vNIC followed to restore.
would be - this sense being or support for Vmware and Microsoft http://www.vmware.com/files/pdf/exchange-2010-on-vmware-support-and-licensing-guide.pdf ?
If yu have any other suggestions, please let me know here.
Thanks in advance.

Hey AlbertWT,

I'll start by saying that I would not do. Microsoft is explicit that snapshots are not supported with Exchange when virtualized. See below (from Exchange 2013 Virtualization: help Exchange 2013):

Some hypervisors include features to take snapshots of virtual machines. Virtual machine snapshots capture the State of a virtual machine while it is running. This feature allows you to take several snapshots of a virtual machine and then return the virtual machine to a previous state by applying a snapshot to the virtual machine. However, virtual machine snapshots aren't application aware, and using them can have unintended and unexpected consequences for a server application that manages the data of the State, such as Exchange. Accordingly, making snapshots of the virtual machine to a virtual guest computer Exchange only is not supported.

Even if we ignore the statement of support from shadow copies that isn't always a good idea. Here are some things to consider.

(1) cumulative updates for the Exchange to modify the Active Directory schema. Roll back the snapshot on the mailbox server is not undo changes made to RFA, which could cause functional supported questions. See this link to give you an idea of how there is pattern AD updates in each CU Exchange and service pack: the Active Directory in Exchange 2013 schema changes: Exchange 2013 help

(2) it is possible to send to come during the time you test the update, and if you need to restore you would need a plan to retrieve this e-mail. Third party services may work, or you can prevent the email to come in your environment completely during this period, but these aren't the ideal solutions.

A much better solution would be to create a lab environment that is isolated from the production. You can either take clones of your Exchange and AD VMs and put them in a closed network environment, or create a laboratory and import the structure of your ad if it matches the production. I think it is a much better way to test than to try to rely on stereotypes in production.

Hope that helps!

Is it possible for a flex application to reproduce a structure of files and folders to the customer without zip

I have an upload/download of flex based app that works very well for download, but when it comes to download, I have coldfusion zip files and folders together and then just by downloading this single file. I would like to have the flex application to replicate files and folders on the clients computer without having to zip & unzip them and I was wondering if this is even possible. If I remember correctly, I thought that flash could not create folders on the clients computer...
Thank you!

a desktop AIR application can write files/folders to the users ' computer

a web application could not

Dynamic form (goes and comes without loss of data!)

Hey there!
I am in a bit of a pickle... especially since I'm not very goot with AS2...
Here's what I'm trying to do:
http://www.isleekdesign.com/customtravel.swf
It is essentially a shape with 6 pages that you can scroll backward, if you missed some information and want to go back for review.
I think the concept is good, but I'm not sure how to actually run.
Here is a screenshot of the timeline, so get you an idea of how I did it (but you probably know it already...):
http://www.isleekdesign.com/timeline.jpg
I did create a mask and shape scrolls... it going forward until that 45 frame, then it goes to the rear.
For example, if we are on page 2 of 6 and retaliate, he plays the animation "backwards" and jumps to frame 1 (of course plays don't step back, but with a ' gotoAndStop (1) '; command).
The problem is that if I fill, say that all of the information on page 1 of 6 and then scroll down... when I come back to this page, the info is lost.
Here's what the form looks like:
http://www.isleekdesign.com/Scene1.jpg
I have named each text entry and checkbock accordingly, but am not sure how to get the input data actually stick to each field so that the "coming and going" actually works...
Any ideas on how to achieve this? The next step is to send the form to a php script... But first things first
My * guess * is that a script should be added when I hit the "next" button, so that it sticks the field values (what the user has typed) in each field and stays there. This will also help collect information of each page for when it is ready to be sent.
Thank you in advance to anyone who can help me. I'm ready to download the .fla is necessary.
Kind regards

Save all data (in variables), before leave you a page.

for example, create your instance of loadvars to send when you initialize your app (before you get on the pages of form):

var sendLV:LoadVars = new LoadVars(); Initialize, so it is not crushed. You may even need:

{if(!sendLV)}

var sendLV:LoadVars = new LoadVars();

}

Then, before leaving a page, wrap through all your textfields and record the input data to sendLV:

sendLV.name = nameTF.text;

sendLV.address = addressTF.text;

.

.

.

etc.

When you enter a loop of the form through your textfields page again to see if all the data was stored:

{if(sendLV.Name!=undefined)}

nameTF.text = sendLV.name;

}

{if(sendLV.Address!=undefined)}

addressTF.text = sendLV.address;

}

.

.

.

etc.

not only this will prevent loss of data among users of flash and frustrating, but you will be all set to call your script php with your populated loadvars.

Loss of all control files and two independent of the system tablespace data files.
Hello

Loss of the controlfile and 2 data files: February 25, 2010... 15:00

Database: in Archivelog mode

Backup: controlfile and all (6) datafiles on February 20, 2010 and all archive logs are available up to the failure

-Wanted to recover.
Even if the controlfiles are restored from a backup, as long as the archive + online redo logs are available, you can make a FULL recovery.
At the end of the recovery, an OPEN RESETLOGS would update the controlfile with correct information about SNA sequence # and headers of files.
(Of course, the RESETLOGS would mean a new incarnation is created and log sequence numbers start from 1 - if you perform a backup as soon as possible after the RESETLOGS).
