Recovery :: AG Database In Reverting / In Recovery State
Nov 1, 2015
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?
Pages on a full recovery model database corrupted, need to ensure data loss is minimal for restore operation am thinking about restoring the latest full backup.
I noticed that after a SQL AlwaysOn failover, one of the DB in the secondary replica is stuck in Restoring state. The primary replica shows that it is in a synchronized state. These are the error logs from SSMS. How do I trace the cause of the problem?
Error: 5901, Severity: 16, State: 1. Nonqualified transactions are being rolled back in database for an AlwaysOn Availability Groups state change. Estimated rollback completion: 0%. This is an informational message only. No user action is required Error: 18400, Severity: 16, State: 1.
One or more recovery units belonging to database  failed to generate a checkpoint. This is typically caused by lack of system resources such as disk or memory, or in some cases due to database corruption. Examine previous entries in the error log for more detailed information on this failure.
The background checkpoint thread has encountered an unrecoverable error. The checkpoint process is terminating so that the thread can clean up its resources. This is an informational message only. No user action is required.
I recently configured SQL Server 2012 AlwaysOn Availability group using two nodes - a primary and one secondary read only replica. Â The group is residing on a windows 2012 cluster with an smb file share as the quorum. Â I am able to successfully failover through SQL and through the windows 2012 cluster. Â When I look at the group dashboard on the primary server and view the Operational state of each node I notice an odd value. Â The secondary role server is listed as Unknown. Â I also noticed that the Availability replicas node icons in object explorer are displaying the same icon on the primary server but on the secondary server, the primary server is shown as a server with a question mark.
Am I missing a permissions setting or is this normal behavior.
For example:
ServerA is the primary ServerB is the secondary ServerA Â lists the servers in Object Explorer as:
ServerA (Primary)ServerB (Secondary) ServerB Â lists the servers in Object Explorer as:
ServerAÂ ServerB (Secondary)
The primary is never listed a primary on the secondary server. Â Again failovers are working properly, but I want to be sure I am not missing a setting somewhere.
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.
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.
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
If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?
We have SQL cluster installed on top of windows cluster on VM environment. Node1 and Node2 under Windows Failover Cluster. SQL instance is currently on node2 the instance is up and running, but SQL Cluster service remains online pending and it restarts the instance on every 5 minutes.
SQL Browser service are running successfully.TCP/IP ports are enabled and configured.If we start the SQL server agent it is on for seconds and stopped immediately  .Cluster Service is attempt to connect to the SQL service every few minutes (setting in SQL cluster resource) for the IsAlive check, if this fails then the SQL resource is restarted even if the instance was online. Hope this is what happening exactly.

Running SQL version 7 on "Terminal" Server I have a database marked in Load Receovery and we are unable to get to it. We tried MS SQL document on how to but we are still unable to recover it!
hai! i have a database which crashed recently(26th sep 2007).my last backup is on 14 sep 2007.i have restored database after two days.Now i have a database (old) with data upto 14sep 2007 and from 26sep to till date.(data from 14sep to 26sep missing).I restored database on 28th with a new database name which has data upto 26th sep 2007.how to attach these two databases to a single database to have data from beginning to tilldate.
Hi, I made an UPDATE query without specifying any criteria so I had more than 1500 records have been changed and I cannot undo the UPDATE. Is there any way I can recover the data UPDATE from the Transactions Log. I did not back up the database lately so what is the appropriate solutions for this?
Is there a way to Revover a Sql Server 2000 database in the absence of the backup file(the backup file got overwritten). Does Sql Server do any automatic Transaction logging?
SQL Server 2005 Database, So I want to know about Database Backup and Pointing Recovery concepts..so can u please help me and any send me related documents...

Hi,I'm no where close to a SQL Server expert but we're using it as a back endto 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 SQLServer installation on another PC. When I tried to attach them they are notrecognized 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 shouldit be possible? Do the .mdf and .ldf files contain specific info about whatPC they were created on?Are there third party apps that might be able to at least extract thetables?Thanks,WH
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.
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?
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...

Could it be dangerous trying to kill this process ? If not, what is the best way do to it ? From Sql Server Activity Monitor (spid 24) or from Task Manager ?
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 ???)
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?
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'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?
MS SQL-Server 7.0Bypassing recovery for database 'EfW_765' because it is marked IN LOAD.What does this mean?Our customer is backing up is maindatabase and is recovering it to thisdatabase for testing.Our custumer tries it serveral times and then the recovery works and thedata are corrupt.I have written a little programm which does some selects to this database.The program is stopped during recovery but our customer beleves that thishas something to do with our program.http://support.microsoft.com/defaul...kb;en-us;272683This article doesnt halp me much. So hwat is the meaning of IN LOAD and whatdoes the server do if it bypasses the recovery.THXJens
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)
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
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?
