Transact SQL :: Change Db In Recovery To No-recovery And Restore Transaction Log?
May 5, 2015in 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.
Do SS Transaction Logs Have To Be Backed Up For Recovery To POF?
Aug 17, 2006Coming 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

View 20 Replies View RelatedTransaction Log Still Growing When In SIMPLE Recovery Mode
Dec 3, 2007hi,
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?

Oct 12, 2015I'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.
View 3 Replies View RelatedRecovery :: Instance Still Accessible If Transaction Log Reached Maximum Size?
Oct 12, 2015One 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?

Data Recovery??
May 14, 2001Hi,
I have SQL 7.0, SP2 running on NT 4.0 with SP5. I have a central publisher and
numerous subscribers using nightly merge push replication. There seems to be some
problem with the rollback after a failed attempt at replication. The publisher
states that there was no response from the sub database and that it was suspect.
From the sql logs on the sub, I can see that the db went into recovery mode,
recovered 100%, howerver all the data in the subscribing database has disappered.
The schema of all the tables is intact and the database still reads at its old
size ~2Gigs. I can't see the data though. The publisher or other subscribers have
suffered no similar loss of data. It seems that there was some sort of error when
the database was trying to rollback to where it was before the attempted
replication. Has anyone experienced anythng similar? Anyone know how I can
recover the data?
I ran a dbcc checkdb, but it reported no errors, saying that there were no rows
in any of my replicated tables.
Any help / suggestions are appreciated.

Dec 5, 2002Hi All!
I made a big mess recently and i need an urgent help. We have 12 months of our company data located in 2 sql servers out of which one server contains 9 months of data (Say A)and another contains 3 months of data (Say B).
The server which contains 9 months data was taken a backup in June 1st week and this is the last backup to the databae in this server.
Now i have tried to append the 3 months data to the 9 months data. So i selected the export option of the B and overlooked the option of "Delete destination objects first".
This creared the disaster. It deleted all our 9 months data in A and wrote down the 3 months data in B.
Now i need to receover the 9 months data in A which was deleted.
Any help please.
I tried with Logexplorer evaluation version but it permitted me to only Northwind and Pubs database.
And also i have tried some other tools like MS SQL Recovery but as evaluation products they didnt helped me completely.
Please let me know if you have any other ideas.
Iam in complete risk, now. :(
Regards,
Satish.

The data base is backed up fully daily to another physical server (B).

Point to be noted is, there isn't any dedicated storage (NAS or SAN) just local disk storage on the server.
The reason for this is they want to run reports against this data every 10-15 mins...

Recovery Model To Be Used For A Data Flow Task
Feb 13, 2007
Hello there
I have a SSIS 2005 DTSX Package which has several Data flow tasks which directly dump data between tables from 2 different databases.
Suppose if my destination database is named, DestinationDB, what recovery model should I select for this database so that my ldf file size does not explode? I want to keep the ldf file as small in size as possible.
Currently I have used Simple Recovery model, and the ldf file size goes to around 80 GB. (Inserting around 200 million rows)
Will Bulk Logged model be a better option?
Also what does a SSIS 2005 Data flow task use internally? (Insert operation or some sort of Bulk Insert between DBs)
Please help.
Recovery :: AG Database In Reverting / In Recovery State
Nov 1, 2015We 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?
