Errors in file /data01/app/oracle/diag/rdbms/ndsd/ndsd/trace/ndsd_arc3_15667.trc:
ORA-00313: open failed for members of log group 2 of thread 1

ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
But there were changes done to the database up to yesterday 4 PM and need to recover completely.
Appriciate if some one can advice me on this issue

I could recover the database and thank youGood. Now that you've put out the fire, you need to be finding out how it was you lost all of your redo and make a plan to prevent it from happening again. To that end ..
Let me guess .. since your redo logs were named something dot log, someone was doing some housekeeping and thought there'd be no harm in deleting a log file. Up until 10g, the default names for redo logs was *.rdo. Shortly after my first upgrade to 10g, with the default of *.log, I twice had to recover due to some SA reclaiming space by deleting "log" files. Since then I've continued to name by redo logs *.rdo.
And whether that was the cause or not, I hope you now see why it is strongly recommended that your multiplexed redo logs - the different members of each group - are as physically separate as possible. Ideally, they are on separate physical discs going through separate disk controllers. But at the very minimum they should be in separate directories to at the very least protect you from "rm *.log"

I guess in the event of lost archive logs during db recovery, you have to open RESETLOGS and say goodbye to some of the data.

Recover datafile using redolog file

Hi all,
please let me know if we can recover datafile using redolog file.
As my database has no archive log mode ON.
Thanks and Regards

Hi,
For your information: NOARCHIVELOG mode protects a database only from instance failure, not from media failure.

Anybody knows if the source code of scadm tool is available somewhere ? (opensolaris etc. ?)
I don't have any additional advice to offer other than asking that you to try the flash-update all over again,
one more time, as if it were the beginning again.Yes but how because the SC is not discovered anymore by Solaris :
"rmclomv: WARNING: DP_GET_SDP_VERSION failed, ret=4"
"The SC hardware could not be initialized."
Can you try to flash the mainalomfw ? Your log contained only the flash of the alombootfw !
/usr/platform/`uname -i`/sbin/scadm download alommainfw
I guess jumper JP2 allows to recover from a failed flash by selecting the un-touched half the PROM.It does not work as the SC is not responding anymore to Solaris
Sun Microsystems Inc. SunOS 5.10 Generic January 2005
v210:~#
v210:~# cd /usr/platform/`uname -i`/lib/images
v210:/usr/platform/SUNW,Sun-Fire-V210/lib/images# /usr/platform/`uname -i`/sbin/scadm download alommainfw
scadm: The SC hardware could not be initialized.
v210:/usr/platform/SUNW,Sun-Fire-V210/lib/images#
ERROR: ERROR: Unable to open the SC device.
It's a pitty that obtaining OBP/ALOM updates requires a service contract. I got a V210 recently.
Unfortunately both OBP and ALOM are the intial release 4.8.2 / 1.0.I agree but it's probably also because you need support in case it fails ;-)
Thanks for your answers!

How to Recover an Excel File for Free
Check the Recycle Bin--if you've accidentally deleted the file, it should still be there unless you've emptied the bin, and you can click on the file and
recover it.
Use the Auto Recovery Pane when you open Excel. Review the document recovery pane. If Excel has managed to recover your file, it will show in a separate
pane on the left-hand side. Identify your document in the pane, then click on it and choose "Open" to open the recovered file.
Try manually repairing the file. Click on "File" in Excel 2003 or the "Office" button in
Excel 2007, then select "Open" and click on the arrow next to the "Open" button. Click on
"Open and Repair" and choose from two options: click on "Repair" if you want to try to completely recover the file, or click on "Extract
Data" if you previously tried Step 1 and it did not work.
Search for the file manually on your computer. When performing a system search (click "Start" and select "Search" in Windows XP and
Windows 2000, or press the "Windows" button and "F" key in Windows 7 and Vista), make sure you choose "Advanced Search Options" and then check the "System and hidden files" check box. You may be able to find your missing
or corrupted file using this search: double-click on the file name in the search results to open it.

How to recover datafile.when control file auto backup is off

hi friend
i took hot backup of my database using following command
rman>backup database;
in my case controlfile auto backup is off.
and i have lost my all controlfiles as well as datafiles except spfile.
i have recovered control file using dbms_backup_restore package.
know i am able to mount database using following command
rman> startup mount;
when i wrote following command
rman> restore database;
i got following error
RMAN-06023: no backup or copy of datafile name found to restore
enven i have backup of datbase.
can anybody tell me how to recover datafiles in this case.
thanking you
sohail

hi,
I think you might have a problem here as the error from RMAN is described in the following metalink note
Doc ID: Note:100565.1
You should change you backup script to be something like
rman {
backup database include current controlfile;
do you have any earlier backups of your database?
regards
Alan

How to recover all lost data after iOS5 upgrade?

After upgrading to iOS 5, my iphone went online without any old files on it. I followed instructions on screen to restore from iTunes, but it gived error. When I restarted iTunes it turned into backup mode, and of course overwriten the old backup file. Now that I lost everything, how to recover it back?

Welcome to the Apple Support Communities
Migration Assistant creates a new user with your restored data from your Time Machine backup, so it's normal that you don't see your data.
Open  > Log Out, and log in the new user that Migration Assistant has created. Here are all your transferred data from your Time Machine backup. Then, if you want, open System Preferences > Users & Groups, select the old user and press the - button to delete it

How to recover deleted back-up file(s) from iTunes?

I'm needing to figure out a way to recover back-up files that iTunes removed during the recent install to the update 11.0.1.
I went to back up my phone manually. (Which I've been doing for years) I've never used or enabled auto-sync. Before I start a back-up I re-name my phone in a format like this "iPhone0913" This is to eliminate any confusion. That iTunes might try to interpet as, a duplication of another back-up file. By it having the same name (Which I know it won't but I do it anyway) Before the installation of the new update. I had 8 back-up files all dated and in order with the name designation that I've proivded. For example: 1. iPhone0105 2, iPhone1106 etc. as the numeric designation is for the month and year. So Oct. 2005 was my oldest back up file.
Once the installation/update took place, I plugged my phone in and clicked on back-up to this computer. All was moving along as it should, since this was only a back-up. Not a back-up and restore!! At any rate, I went through iTunes to verify that the back-up was there. (As I always do) And low and behold.. GONE!!
The only back up that was showing, was the back-up of "iPhone0913" I did'nt go into panic mode at that point. Thinking that maybe iTunes moved or maybe archive the back-ups. I was trying to remain optimistic, but I knew there was'nt much that could be down. But maybe, I'm missing something.. I was able to locate 4 of 8 back up files. Only because I had backed them up from another drive.
I don't have Windows System Restore, enabled, So I was'nt able to recover that way. I'm still beside myself that this even took place.
At this point, I'm looking for any recommendations, sympathy.
Thanks in Advance for your help and support!

How to recover database from .mdf file

create a database of
equal size to the one you're trying to attach
shutdown the server (Stop)
swap in the old mdf file (replace new .mdf file with .mdf file to be recovered )
Location: C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA
bring up the server (start) and let the database attempt to be recovered and then go into suspect mode
put the database into emergency mode with ALTER DATABASE
run DBCC CHECKDB (dbname, REPAIR_ALLOW_DATA_LOSS) which will rebuild the log and run full repair
Your database will be available again but you'll have lost data and the data won't be transactionally consistent
USE [master]
GO
ALTER DATABASE [RdmStoreInformation] SET EMERGENCY
GO
ALTER DATABASE [RdmStoreInformation] SET SINGLE_USER
GO
DBCC CHECKDB ([RdmStoreInformation], REPAIR_ALLOW_DATA_LOSS)
GO
ALTER DATABASE [RdmStoreInformation] SET MULTI_USER
GO
ALTER DATABASE [RdmStoreInformation] SET ONLINE
