Is it anything related to Master Data Services or just a generic question for SQL Server Agent?
I guess its generic question and must be moved to database engine forum

etc/system file corrupted how to recover it?

with boot -a you can only specify new /etc/system during boot , e.g. /dev/null
but if you want to recover it , you can do it from live kernel ( if you didn't reboot after /etc/system was corrupted )
with
echo ::system|mdb -k
or from previous crash dump simmilar way
cd /var/crash/`uname -n`

PDF files corrupted, how to recover them?

I am using ubuntu 11.04. Few days ago, I installed wine to run .exe programs on the system. Somehow .exe virus flooded into the system & the entire system has got corrupted. Now I am unable to view pdf files as all of them are corrupted. How can recover them now?

Some viruses destroy all PDF (and other types of file) on the system. If this is the case, they are gone, and you need to restore from backup.

N86 E: Mass memory corrupted - how to recover?"

Hi,
I'm using a N86 8MP which is less than 5 months old. Recently, I have lost all my music files and all the crucial photo images which I have taken between Jan till now and I have not done a backup yet. Somehow this occurs after I have switched the Singapore SIM Card to a China Prepaid Card. Could it be the cause of data losses? Also, not sure if the missing data has anything to do with the corrupted E:Mass Memory which I have just discovered yesterday.. Any ideas/advise?
And, may I know, how can I recover the corrupted E:Mass Memory from my Nokia N86 8MP phone?
Please help. Thanks!

Thanks for the suggestion, Barney-15E. FYI I am not running both iCal and Calendar. Just Calendar. Me bad for using the old name and new name interchangeably.
Tackling the iMac problem: In iCloud network preferences, I unchecked Safari then soon after rechecked it, and your suggestion appears to have worked: a bookmark recently added on one of the other devices appeared in the iMac Safari bookmarks. So far so good.
Did the same thing with contacts. The iMac took a couple of hours to restore the sync setting, but it finally completed the task. The computer was laboring so I rebooted. Then I opened the contacts application and saw the spinning grey bars next to the "iCloud" heading above my list of contact groups. Some time later the spinning lines were replaced by an exclamation point. I clicked on it and got the message that the operation could not be completed because of a "CoreDAVErrorDomain error 1..". Subsequently, after much spinning of the line wheel, I have gotten either the exclamation point with the CoreDAV message or a lightning bolt icon. Whether exclamation point or lightning bolt, clicking on it provokes a long period of the spinning line wheel. And looking at some telltale contact discrepancies between the iMac and the other machines, nothing seems to have changed in terms of merging the discrepancies.
Searching for the error message in the support community, I see this has happened to others, and they have had some success in following a list of steps starting with archiving the contacts, which I have done. Don't think I fully follow the other steps, nor am I sure they apply to my situation.

How to recover WSFC / SQL setup

We had small domain consisting of a Windows domain controller and two Windows 2008 R2 servers running SQL 2012. The SQL servers were part of a WSFC, and set up with a AlwaysOn Availability Group. The DC also hosted the Witness
File Share.
We had a problem with the domain controller that caused it to be recreated from scratch, so it is brand new, SIDs and all.
After the failure of the DC we took steps to get one SQL server back in service so the Web servers using its services could stay up. On the primary SQL server, the AlwaysOn Availbiltiy Group was deleted. In the Web servers
that used the databases, the connection strings were altered to go to the node instead of the Virtual name. There may have been some other changes, but I'm not sure. If something else is important to know, I can find out.
Today I the SQL server still providing services to the Web servers, a new domain controller, and an unused out of date SQL server that can't make quorum.
I have removed the unused SQL server from the old domain and have added it back to the new domain. (Names haven't changed but I know the SID has).
I was wondering what the steps would be to recover my systems so they are all working correctly again. How do I get things cleaned up that are no good on the unused server and when can I do it? What things should I watch out for?
How do I keep down time to a minimum?
The SQL server has 6 user databases that have an initial size of 5 or 6 GB each.
I'd appreciate it is anyone can provide the recovery steps for this situation. Thanks.

Scott,
Based purely on what you have written, there would be no good recovery option as you're wanting to completely change the environment (which has already been changed).
Starting with the "old" node that wasn't being used, wipe and re-install windows and SQL Server (clustered instance). Setup mirroring, logshipping, or take a down time to sync/migrate the databases to the new FCI instance. Finally take out the
other AOAG SQL Server node, wiping it and adding it as a node to SQL Server once windows is installed/configured, etc.

My iMac HD got corrupted how to recover data?

My iMac HD got corrupted and had to clean format it. Any freeware applications to recover all the data? Specially Documents and images?
I am in deep trouble and need to recover the files soon..
I cannot afford paid softwares right now.

There is no FREE data recovery software.
AND data recovery services are not free either.
If you do not have a backup of your important data and/or system, you are out of luck.
If you can' t afford to purchase any data recovery software I don't suppose you can afford an external hard drive, either?
WIth an external hard drive, you could install OS X and run your Mac from the external hard drive and not use the internal drIve, at all, until you can afford to buy the data recovery software that you will need.
Other than what I have covered here, you have ran out of luck.
Sorry

Table Truncated, Flashback is enabled ... How to recover.

Hi,
There is a table which was truncated, as we have flashback enabled. Even we have previously enabled row movement of the particular table.
How to recover ????
Thanks.

hi,
There are three options available:
1. Restore and recover the primary database to a point in time before the drop.
This is an extreme measure for one table as the entire database goes back in
time.
2. Restore and recover the tablespace to a point in time before the drop.
This is a better option, but again, it takes the entire tablespace back in time.
3. Restore and recover a subset of the database as a DUMMY database to export
the table data and import it into the primary database. This is the best option
as only the dropped table goes back in time to before the drop.
For the first, see information on performing incomplete recovery on a database.
The second and third options are virtually the same, it depends if the entire
tablespace data should be taken back in time, or just recovering the one table.
The tablespace point in time recovery (TSPITR) may be useful if there are
dependencies between the dropped/truncated table and other tables in the
database. For the second option, see RMAN documentation on TSPITR and/or Note 180436.1 RMAN Tablespace Point in Time Recovery Example. Both procedures
for the second and third options are very much the same. The differences are
that the TABLE PITR has to be exported/imported manually while the TABLESPACE
PITR is fully automated by RMAN.
This article will deal with the third option.
General overview of procedure to recover from a DROP or TRUNCATE table by using RMAN.
To recover from a dropped or truncated table, a dummy database (copy of primary)
will be restored and recovered to point in time so the table can be exported.
Once the table export is complete, the table can be imported into the primary
database. This dummy database can be a subset of the primary database. However,
the 'dummy' database must include the SYSTEM, UNDO (or ROLLBACK), and the
tablespace(s) where the dropped/truncated table resides.
The simpliest method to create this 'dummy' database is to use the RMAN
duplicate command. See:Note 228257.1 RMAN Duplicate Database in Oracle9iNote 73912.1 RMAN Creating a Duplicate Database -- Oracle8i
The difference between the two versions is that Oracle9i duplicate command
allows for a 'SKIP TABLESPACE' option. Thus Oracle9i allows for a duplication
of a subset of the database.
In Oracle8i, you cannot 'skip' tablespaces when using duplicate, so you must
duplicate the entire database. If this is not a desired option, or you must
restore the original database and thus cannot use
the rman DUPLICATE.
NOTE: The remainder of this information is for users who cannot use the
DUPLICATE command in Oracle8i. I.e., you want to restore only a subset
of the Oracle8i database.
Requirements :
a) RMAN backup of the primary database should be available to the
host where it has to be restored on.
b) Use of an RMAN-catalog database
c) Auxiliary instance created and started in NOMOUNT
(See Note 180436.1 step I. Create the auxiliary initSID.ora.)
Create this from the init.ora of the primary database and:
!!!!! IMPORTANT !!!!!!!!
If using the same host as the primary, be VERY careful as you do not want to
restore on top of existing files being used by the primary (production database).
Doing so can corrupt and crash the production database!!!!!!
- be sure all paths for this AUX instance are different than primary.
- be sure CONTROL_FILES parameter has different location but more importantly DIFFERENT NAME.
- add LOCK_NAME_SPACE to any value other than the primary database name.
- change/add SERVICE_NAME=AUX1.
- use the SAME DB_NAME as for the production database
- BE SURE you include the 'alter database rename file' command at the end
of the script. This changes the location and/or name of the online
redo log files.
d) Set ORACLE_HOME and ORACLE_SID set to the auxiliary instance
e.q set ORACLE_SID=AUX1
set ORACLE_HOME=<....>
!!!!! IMPORTANT !!!!!!!!
1: Restore and recover the tablespace
The restore and recovery is done by RMAN. Create a file
of the script below (e.q table_pitr.cmd) and execute the following
command :
$ rman cmdfile=table_pitr.cmd
NOTE: ORACLE_HOME and ORACLE_SID set to the auxiliary instance
NOTE: The Auxiliary instance IS the target to rman at this point.
The RMAN-script :
connect catalog rman/rman@v920_nlsu31
connect target /
run
allocate channel t1 type sbt_tape
parms='SBT_LIBRARY=/home/usupport/liblsm.so';
set until time "to_date( '09-10-2005 06:00', 'DD-MM-RRRR HH24:MI')";
restore controlfile;
sql "alter database mount clone database";
set newname for datafile 1 to '/fs01/oradata/tspitr/system01.dbf';
set newname for datafile 2 to '/fs01/oradata/tspitr/undotbs01.dbf';
set newname for datafile 4 to '/fs01/oradata/tspitr/tools01.dbf';
restore tablespace system, undotbs1, tools;
switch datafile all;
sql "alter database datafile 1,2,4 online";
recover database skip forever tablespace TEMP,INDX,USERS,OLTS_ATTRSTORE,
OLTS_CT_DN,OLTS_CT_CN, OLTS_CT_OBJCL,OLTS_CT_STORE,OLTS_DEFAULT,
OLTS_TEMP,OLTS_IND_ATTRSTORE,
OLTS_IND_CT_DN,OLTS_IND_CT_CN,
OLTS_IND_CT_OBJCL,OLTS_IND_CT_STORE,
P1TS_ATTRSTORE,P1TS_IND_STORE;
sql "alter database rename file ''/fs01/oradata/primary/REDO01.LOG'' to ''/fs01/oradata/tspitr/REDO01.LOG''";
sql "alter database rename file ''/fs01/oradata/primary/REDO02.LOG'' to ''/fs01/oradata/tspitr/REDO02.LOG''";
sql "alter database rename file ''/fs01/oradata/primary/REDO03.LOG'' to ''/fs01/oradata/tspitr/REDO03.LOG''";
/* NOTE: Syntax within rman is two single quotes around each name, this may be operating system specific. */
release channel t1;
Explanation :
- Tape channel allocated, but could also be a disk channel, depending
on where the backups are.
- SET UNTIL TIME
User specified time, just before the DROP/TRUNACTE table
- MOUNT CLONE DATABASE.
This forces all datafiles to be put OFFLINE. Just for safety reasons.
- SET NEWNAME
New path for the datafile to be restored. Keep in mind that this is
done on the auxiliary instance and should NOT interfere/overwrite the
prodution database.
- ALTER DATABASE RENAME FILE
This is required to change the location of the online log files. When the
'resetlogs' is issued, Oracle will create online logs based on specification
in the controlfile. This command changes the location and/or name. If
this is being performed on the SAME server, not issuing a rename will
cause Oracle to reset the production online log files. This will corrupt
and crash the production database!!!!!!
- RESTORE TABLESPACE ...;
Restore the tablespaces which need to be recoverd.
This includes always the SYSTEM, rollback/undo tablespace and
the tablespace(s)where the dropped/truncated table resides.
The SYSTEM tablespace is always included as it containts most / all of
the objects owned by SYS and SYSTEM. Some other tablespaces might be
included as well when they contain objects owned by SYS and SYSTEM.
SQL> select distinct tablespace_name
from dba_segments where owner in ('SYS', 'SYSTEM');
- SWITCH DATAFILE ALL;
Make the changes in the pathname (set by SET NEWNAME) active in the
controlfile.
- ALTER DATABASE DATAFILE ... ONLINE
Online the datafiles which are restored and have to be recovered.
- RECOVER DATABASE SKIP FOREVER TABLESPACE ......;
You need to specify the complete list of tablespaces which will not be
recovered. Else the recovery fails, that it cannot dentify/file the
tablespace datafile. The SKIP FOREVER clause causes RMAN to take the
datafiles offline using the DROP option. Only use skip forever when the
specified tablespaces will be dropped after opening the database. I.e.,
all tablespaces except the one which contains your data.
The recovery of RMAN, checks the datafileheaders, to get a starting point
for the recovery.
2: Open auxiliary database with RESETLOGS
$ sqlplus /
SQL> alter database open resetlogs;
This step should ALWAYS be executed outside RMAN via SQL*Plus. If the open
is executed in RMAN it may effect the primary database's entry in the RMAN
catalog. Backups will fail with messages like:
RMAN-20011 "target database incarnation is not current in recovery catalog"
3: Export the table
The database is recovered and open, so it can be used by export.
Example:
$ exp userid=system/<password> file=table.dmp
tables=(<owner>.<tablename>, ...) rows=Y
4: Import the export-dump
Import the data of the dropped table back into the primary/production database.
Example:
$ imp userid=system/<password> file=table.dmp ignore=Y
5: Remove this AUX/DUMMY database
Shutdown and remove all files associated with this database. It has satisfied
your purpose. I.e., to give you an export of this table.

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 corrupted partition table?

I have a disk that somehow got the partition table corrupted. I am getting lots of "Bad Geometry" errors that state the label says one size while the drive says something different.
I have tried running the TestDisk (http://www.cgsecurity.org) application, and it seems to find the partitions just fine and I believe that my data is in tact. I just need to correct the partition table and access the UFS file system. The TestDisk reports that "write_part_sun" is not implemented, so it cannot correct the problem. I have checked the source code for the current and beta versions of the program and the function still has not been written.
Is there another application that I can use to rescue my corrupted partition table? I am not finding much support for Solaris out on the net.
Thanks.

Is there another application that I can use to rescue my corrupted partition table? I am not finding much support for Solaris out on the net.Hi
There is some, but you have to look hard.
I wrote a partition table editor:
http://paulf.free.fr/pfdisk.html
If your LBA values are good, you should be able to restore the CHS values from them. If both the LBA and CHS values are corrupt, and you have a good idea of the sizes of the partitions, then with a calculator you should be able to work out what the values should have been.

How to transfer the tables from one file group to another file group in SQL 2008.?

Hello all,
I have few issues regarding the transfer of the tables from one file group to another file group  in SQL 2008 and also How can we  backup
and restore the particular database based on file group level.
Let’s say I have a tables stored within the different FG. such as
Tables
  File group
Dimension tables
Primary
Fact tables
  FG1
FG2…
zzz_tables
  DEFAULT_FG
dim.table1                                                                                                                          DEFAULT_FG
dim.table2                                                                                                                          DEFAULT_FG
Here all I want to transfer the dim.table1 ,dim.table2  from  DEFAULT_FG to the Primary File
group .So is there simple methods for transfer the dim.table1,2  from one FG to another .I have tried somewhat but I couldn’t get the exact way .So if someone have better idea please share your knowledge that would be really appreciated.
Secondly after moving those dim.table1 ,dim.table2 from DEFAULT_FG to Primary ,All I want to backup and restore the database only containing  the Primary and FG1,FG2… not
a DEFAULT_FG.Is it possible or not.?
Hope to hear from the one who knows better approach for this kind of task .Your simple help will be much appreciated.

Anil Maharjan

Well after all my full day research on this topic had paid off, I finally got the solution and am so happy to research on these things. It makes
us feel really happy after all our research and hard work doesn't goes as waste.
Finally I got what I am looking for and want to make sure that I am able to transfer the tables from DEFAULT_FG to another FG without tables
having clustered index on that tables .
With the help of the link below I finally got my solution where Roberto’s coded store procedure simply works for this.
Really thanks to him for his great post and thanks to all for your response and your valuable time.
