Transact SQL :: Change Db In Recovery To No-recovery And Restore Transaction Log?
May 5, 2015
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.
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 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.

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

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?

I'm trying to RESTORE LOG with a different recovery path. Is there a way to do this? I'm getting the below error. I know I could RESTORE from the beginning, but need to RESTORE the log file to the same database schema but different database and server. What steps do I need to do?
This backup set cannot be applied because it is on a recovery path that is inconsistent with the database. The recovery path is the sequence of data and log backups that have brought the database to a particular recovery point. Find a compatible backup to restore, or restore the rest of the database to match a recovery point within this backup set, which will restore the database to a different point in time. For more information about recovery paths, see SQL Server Books Online.

Hello,
I have a file backup of a database from machine 1. I create an empty database with the same name on machine 2 and copied the backup file to machine 2. When I run a restore database, I get "Preceeding restore operation did not specify WITH NORECOVERY OR WITH STANDBY.Restart tehe restore sequence, specify the options for all but the final step. Restore failed"

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

SQL Server 2008 R2
I don't see a "general discussion" thread and this is the closest i think.
I just have a general question: if my backup window is from 8am to 10am, and i do a restore within that backup window, what will happen? assuming we're talking only of a single database, ACME.
I'm comparing because with Oracle RMAN, it pukes when i do a restore while the backup is going on. it would complain of unable to find some archive logs.

I am trying to imitate a DR situation where the primary db is down and I need to recover the secondary db on another server. They are a log shipping pair and so to imitate a DR, I remove the log shipping in the primary server maintenance plan. Then I go to the secondary server and disable the log shipping jobs there and attempt to do the following
RESTORE DATABASE database_name WITH RECOVERY
but I can't get exclusive use because the database is in use. But I don't see any other users... am I wrong in thinking that the log shipping was completely deleted? Anything I can do to force exclusive access?

I am set up log shipping as backup and copy every one hour and restore every ( disconnect users and stand by) one hour on servers in same domain. Set-up completes successfully.Copy job works as expected. but the restore job fails intermittently to restore the .trn file saying ' could not apply log, data invalid' .
when i delete and copy the files for which restore failed manually using CTRL+C and CTRL+V across network and re run the restore job it does restore successfully . Through out the day i get about 5-6 problematic .trn files on secondary server which are copied from primary server and when restore fails i have to manually delete the log file which had problem restoring and then copy that file again using CTRL+C and CTRL+V then run the restore and it gets restored successfully.when running restore filelistonly on the logfile in issue on secondary server it gives below error
Cmd:
RESTORE verifyonly
FROM disk='G:xxxx_Copyxxx_20150604010501.trn'
Error:
Msg 3203, Level 16, State 1, Line 2
Read on "G:xxxxxxx_20150604010501.trn" failed: 13(The data is invalid.)
Msg 3013, Level 16, State 1, Line 2
VERIFY DATABASE is terminating abnormally.
and when i run restore filelistonly using netwok path then is seem s good and i can restore the logs as well
CMD:
RESTORE verifyonly
from disk='1.2.3.4xxx_Backupsxxx_20150604010501.trn'
Output: The backup set on file 1 is valid.I can assure there is no corruption on the log back up, no lsn mismatch, no log files missing.Same version and edition on both servers. Both servers are SQL server 2012 Enterprise edition on window server 2012

Coming from a (mostly) Oracle shop, I am unclear how SS transaction logswork as far as up to point of failure recovery goes.I have the few MSSQL databases I look after in full recovery mode, and Iset up maintenance plans to back these up online on a daily basis. Inthe research I did it was recommended backing up the transaction logs aswell on a frequent basis to ensure recovery to POF or point in time.I had assumed that they work like Oracles archive logs, in that oncethey are full they are archived to disk in case they are needed, toduplex destinations if need be. Does SS do this, or do I need to bebacking up transaction logs on an hourly (or shorter) basis? In lookingat enterprise manager I see that it does not look like the transactionlogs are archived anywhere, but overwritten once filled up, similar toOracle noarchivelog mode, in that if you lose your online redo logs oranyone of them has recycled since your last backup, then you can onlyrecover to the last good backup.Is this a correct assumption? Should I be backing up transaction logshourly to make sure I can have PIT or POF recovery?thanksTG

Now I realze the recovery point is somewhere in TranBackup2.trn and need to go back to the state where only TranBackup1.trn is applied. How can i do this ?

Given the follwoing scenario: You create a snapshot of a database with full recovery model, change it's recovery model to simple, then perform several updates/modifications on the database, before you finally (due to an error) restore the database from the snapshot.
Will the log chain be broken or not? The resteore sets the recovery model back to full, but I'm still a bit "curious" about the transaction logs.

I make two full backups on Oct 1 and Oct 10. I want to restore the server to a state in Oct 5. So I just do as follows:
Perform a transaction log backup on the server on Oct 23. I have never backup transaction log in the past. Restore the server with Oct 1 full backup with NORECOVERY option.Try to restore to the point at Oct 5 12:00, with the transaction log.
But the restore fails and SQL Server said the transaction log does not contain the point. The point is too early. Why? Also my .LDF file is about 13G, but the transaction log backup is only 200MB. Why?

how to restore database backups with different recovery fork. I have 1-full backup 2-diff backups and 10-tran backups. My prod database in mirror, so after error, switched to mirror with "allow_data_loss" option. And now I have full and diff backup with one recovery fork GUID and other backups with another GUID.So the question is, how to restore all this backups if in middle of restoration will be different recovery fork.Tryed to restore log backups with new fork guid and got error:This backup set cannot be applied because it is on a recovery path that is inconsistent with the database. The recovery path is the sequence of data and log backups that have brought the database to a particular recovery point. Find a compatible backup to restore, or restore the rest of the database to match a recovery point within this backup set, which will restore the database to a different point in time.

hi,
we have a SQL Server 2000 database which we set to 'SIMPLE' recovery mode at 6pm (due to nightly large data loads). We revert back to 'FULL' recovery mode at 6am.
My understanding was that in 'SIMPLE' recovery mode, the transaction log would not grow because it would automatically be truncated after a checkpoint. However this is not the case. I thought perhaps it could be due to a long running uncomitted transaction, but when I ran 'dbcc opentran', the oldest running transactions doesn't last for more than a couple minutes. I manually run a 'checkpoint' command as well in the hope of forcing the transaction log truncation. I repeat this a couple of times to no avail. When I run 'dbcc sqlperf(logspace)' , I can still see the transaction log growing.
It is not until I run 'backup log db with truncate_only' that the transaction log gets truncated.
I do not understand, why the transaction log does not get automatically truncated in SIMPLE recovery mode?

Hello,
I would like to restore SQL Server Express and its databases from a tape backup to the same server. This is a disaster recovery senario.
I backed up the Master, Model, MSDB and my own test database using SQLCMD scripts. I have no problem restoring these using task manager on the server before the disaster recovery.
However, in my real disaster recovery testing, When the server is restored by tape drive (HP one button disaster recovery), I try to run my SQLCMD restore scripts in task manager and I cannot connect to the sql server. Also I cannot connect with Management studio. I have recieved the following error in event viewer.

My question is, what is the correct procedure to follow when I want to do a disaster recovery and restore SQL Server Express from tape backup using the Simple Backup method and scripts.
Is it always required to reinstall sql server express from the original program file or is it possible to reinstall from back up tape.
I know my backup and restore scripts work because I tested them on the server before I do the disaster recovery and rebuild that server from tape.
This is some kind of issue with SQL Server Express being restored by tape backup.
Any suggestions, thanks.

We are using SQL Server 2012 for both production and development server. Currently, i have plan to transfer the full backup of SQL server database to the development server and then restore it on the development server for testing purpose, so we don't want to disturb on the production.
I have successfully backup the database from the production server and transfer to the development server. however, i encounter some difficulties when trying to do restore. my question is:
1. do i need to firstly create an empty database on the development server and then restore it into this empty database? say i create database call "Test2", then i perform a restore into this database.
2. currently, there is already an existing database being restored previously in the development server and this database is actually the older version of the backup that being restored by the previous engineer. should i remove this database first and restore a new one or both of the database can coexist as long as we put different name for the database?

I've got log shipping set up, and everything seems to be working fine, but the log files are not being deleted from the primary server despite configuring log shipping to retain them for 3 days. I see no errors concerning the log shipping, but did not configure a monitor. What process is responsible for deleting the older log backups, and how can I look for errors. I could simply set up a jog to delete the older files, but that will only mask the issue.

One of our production databases was setup mirroring, log shipping and replication on it, the log file was setup unrestricted growth. This morning one index rebuilding process generated lots of logs, and the log file disk ran out of space, the database was in recovery mode. so we had to disable log shipping, pause mirroring and replication, expand log file disk, restarted SQL instance to fix the issue. Now we want to setup the log file to maximum size 80G, the whole log file disk is 120G.
So if the log file reached 80G next time, we can change the max size to 90G or 100G and it's easier to fix the space issue. My question is, if the database log file reached max size,
1. is the database still available?
2. Will the active session causing the issue be rollback to release space back?
