Database Recovery
Jul 23, 2005
Hi,
I'm no where close to a SQL Server expert but we're using it as a back end
to another application.
I lost a PC that had MS SQL Server 2000. I was able to recover the .MDF and
..LDF files but nothing else. How can I restore these files to another SQL
Server installation on another PC. When I tried to attach them they are not
recognized as valid files (I get the red X instead of the green CHECK).
Is this a basic security function that I'm not going to get around or should
it be possible? Do the .mdf and .ldf files contain specific info about what
PC they were created on?
Are there third party apps that might be able to at least extract the
tables?
Thanks,
WH

We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?

Last week I backed up my SQL Server by using BE 2012. I named the file "SQL Server BAK" which contained copies of my SQL Server databases. A few days ago I lost some part of my data due to accidental deletion. I backed it up, so I tried to restore the database from the .bkf file. The problem comes here, when I try to to restore my .bkf file, it becomes inaccessible.what causes this?

Hello all,
Is there a way to check the status of a database in recovery. Like how far along it may be. If not is there a way to stop a database in recovery and just drop it.
Thanks in advance,

Our server ran out of disk space during a stored procedure process. We were able to free up some space, stopped all SQL services, restarted all SQL services and now SQL Management Studio shows the database to be in recovery. Is there a way to monitor this to ensure progress is being made and to estimate when it might complete?

What does it actually mean when the database is in recovery? My database has been in recovery overnight. What is normally going on in this situation. Should I wait or take more drastic action?

Hi all,
I had to change the path of .mdf and .ldf files, so I decided to:
1) Take offline the database
2) run the quey ALTER DATABASE... MODIFY to change the path
3) Bring online the database.
The last step hung up (with no errors) and left the database In Recovery.
When I tried to stop and restart sql server other databases changed their status In Recovery...
Here is a dump of Errorlog files

We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.

Hi everyone,
I am trying to implement a plan for a SQL7 database that is used by the company I work for. Having read the SQL manuals I have come to the following conclusion:
I want to do a complete backup of the database at midnight and do a transaction log backup every 30 minutes between 7am and 7pm. I am hoping this will allow me to 'undo' any user mistakes and roll back the database changes to the last transaction log backup.
The questions I have are:
1) By backing up the transaction log every 30 minutes, will this then give me the ability to 'roll back' the database to the last time the transaction log was backed up (i.e. 30 minutes max) ?
2) How do I load the transaction log back in ? (i.e roll the database changes back). A simple Restore operation (with truncate ???)
3)Am I totally confused or on the right track ?
Thanks,
Tim

Hi I'm a newbie with a problem.
SQL Server 6.5 SP4. Have had problems today with SQL Server running out of LOCKS. We increased these & all seemed fine. LOCKS ranout again & we brought SQL Server back up our major database started a recovery. I know the spid of the recovery from the SQL Server errorlog but when I select the sysprocesses table I don't find an entry for this spid. The recovery has been running for about 2 hours. My question is should I see the spid of the recovery process in the sysprocesses table & is 2 hours long for a recovery of a 5 GB database?
Thanks for any help in advance.
Cheers,
Phil

Just curious, Has anyone had to do a full recovery and have it take 20+ hours?? If anyone can give me their average times for full recovery and database size, I would appreciate it. I'm researching this topic. Thanks.

I cancelled an INSERT operation on a database. Now I get:
"Recovery of database 'BounceRepository' (6) is 0% complete (approximately 2024654 more seconds)"
That is another 23 days of straight recover time!!! The original INSERT only ran for about 30 hours.
In Windows Performance Monitor, I can see that the system isn't disk or CPU limited. What is the server doing? How can I make it go faster?

Hi All,
I've recently restored one of my development databases from it's production backup. The restore completed successfully, users were able to connect to the database without any problems. However, when I checked the error log I found the following message:
Bypassing recovery for database 'Test' because it is marked IN LOAD.
I could not find anything on the web or in BOL. Any ideas?
Thanks.

in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.Â
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
Msg 3013, Level 16, State 1, Line 1
RESTORE LOG is terminating abnormally.

We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue

Hi
Yesterday a user has run a storedprocedure which
updates a very transaction table having million of
records , as usual the user killed the process in the
middle of the execution.(which has resulted in rollback
action).
this rollback process blocked other scheduled jobs and
its was running for more than 8 hours without completing
as usual decided to shutdown and restart the sqlserver
while restarting the sql server went into automatic recovery
the following are the log recording
2001-04-17 12:00:01.86 spid9 Recovery progress on database 'ISH' (7): 48 percent.
2001-04-17 12:00:37.89 spid6 Using 'xpstar.dll' version '1998.11.13' to execute extended stored procedure 'sp_MSgetversion'.
2001-04-17 12:02:36.60 spid9 Recovery progress on database 'ISH' (7): 49 percent.
2001-04-17 12:08:12.79 spid9 Recovery progress on database 'ISH' (7): 49 percent.
2001-04-17 12:11:49.90 spid9 Recovery progress on database 'ISH' (7): 50 percent.
2001-04-17 12:11:50.32 spid9 Recovery progress on database 'ISH' (7): 92 percent.
if you see the log reading from 50% jumps to 92 % and the automatic recovery
process is running from another 5 hours (now not able to open the database)
in order to avoid the sql server going into automatic recovery mode (usually the dba use to update the master.sysdatabase table the status column with some
magic number to set the database into emergency mode) but i followed my own style (deleting the reocord for the user database from sysdatabases)
and restarted the sql server , and used my monday tape backup (complete bkup) to recover the database. In the recovery option i used force restore over existing database (hoping that this will reduce the database recovery time ,bcaus the data file (mdf and ldf ) need not to be created.
but the result :- after running six hours of loading data from tape ( i am getting the following reading in the log file)
2001-04-17 16:15:58.40 spid7 Starting up database 'ISH'.
2001-04-17 16:15:58.40 spid7 Opening file F:DATABASEISH.mdf.

2001-04-17 16:15:58.65 spid7 Bypassing recovery for database 'ISH' because it is marked IN LOAD.
realy do not what is happening in the background.(if its oracle the dba has
the control over the database . In sql server has the control over the dba)
any one who has any idea on sql server recovery (the size of the database is
22 gb which is recovered and tape device is hp sure store DAT 40 E (DSS-4,4MM TAPE). Thanks in advance
Have a good day (not for me laaa)

Hello all,
I just restored a SQL 7 db using the Enterprise Manager GUI interface. I
selected the "Leave database nonoperational, but able to restore additional transaction logs" option. I should not have selected this option as I do not have any transaction logs to apply.
Anyway, my question is... Is there a way to mark the database as opertational without running the restore again?
Thanks,
Corey

hello, (this was originally posted in Administration Forum)
I am helping out with a disaster recovery of a database and i was given 4 files. 2 MDF and 2 LDF files. When I try to attach the files to SQL Server I recieve this err msg:
Server: Msg 823, Level 24, State 6, Line 1
I/O error (torn page) detected during read at offset 0000000000000000 in file 'E:chivirtualGPS0Dat.mdf'.
Connection Broken
I then tried many other combinations hoping something would work --> tried individual files, just data files, tried to create a new DB and then switching/replacing out with the files i needed...etc, nothing seems to work for me. The people I am trying to help out do NOT have backups.
Any thoughts would be appreciated. thanks...
