We have the following scenario,
We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.
SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.
Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.
It it possible, if yes how can we achieve this.
If not what could be another DR solution in this scenario.
Thanks Much

is bulk logged recovery model support point in time recovery
View 9 Replies View RelatedHi all,I have a SQL Server 2000 database that is using the Full recoverymodel. The database is purely receiving inserts (and plenty of them)with maybe some view/table creation for reporting.In this state I would expect the log to grow ad infinitum but it getsto about 32% used and then empties.The log is not being backed up at all so am I missing something else?CheersDee
View 2 Replies View RelatedI have convert all databases to Full from Simple Recovery model.
As per documentation, it looks like simple.
Based on your experiences , do you think of any problem may come while doing this ?
Any impact on application performance after this ?
Is this work perferened to do when no body using system ?
Thanks
When the SSISDB database is created, it appears to be using the "Full" recovery model by default. Because of the recovery model, the SSISDB transaction log needs to be regularly backed up or I risk running out of disk space.I would like to set the recovery model to "Simple", so that I do not need to worry about the transaction log consuming too much space. However, I am not sure what the consequences of that action are.features lost by switching the recovery model of the SSISDB database from "Full" to "Simple"?

View 4 Replies View RelatedI cannot think of any reason, in our environment, why I would recover the model database. Change framework has all databases coming from DEV & QA before landing on PROD. We have never used the model database as framework of new databases either.
So, if I discontinued backup of the database, what is my recovery method if it become corrupt? Since mine is not used, can I simply copy it from another server?
Hi:
I am having lot of log problems with Subscription databases. Currently all my subscription databases are on Full recovery mode. I am thinking to change them to simple because I don't I will be doing point in time recovery of them.
Do the subcription databases have to be on Full mode? Can I change them to simple to keep my log small and then I do not have to backups of my logs also? Please let me know.
Thanks
Have a database that's in "Simple" recovery mode whose .ldf has grown to 270GB. This database is a data warehouse so "full" is not required. I put it in simple mode a month ago and shrunk the log down and now it's filled up the disk.
What steps can I take to mitigate this in future? I've read that this is caused by long running transactions which fill the log for DR purposes. Should I put the database back into full mode and backup/truncate daily.
The auto-growth is set to 128MB which is very low.
Hi All
Will Rebooting the SQLServer 2000,Is it change recovery model of MSDB Database
Please help...
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?
Log shipping was configured 6 months back. A Transaction log file got corrupted today. How to resolve this?
View 20 Replies View RelatedI have two instances (Source and Destination) on the same server, i did a full backup of a database on the source server, i did a restore on the destination using the NORECOVERY mode, now the database on the destination as green arrow saying "restoring". From the source database i set up the mirroring, i'm using port 5022 on source and 5023 on destination, everything seems to connect fine but when i start mirroring i get the error message "Database mirroring cannot be enabled because the database is not full recovery error: 1465" but when i look at the property of the db on the source the recovery model shows full as so the destination?
View 1 Replies View RelatedWe are trying to restore from a backup (.bak) of a sql 2005 database with full text catologs to sql 2012.
We are getting errors saying that the backup file context are different from what we are trying to restore to, even if we try to create a new database from the backup.The new database is just a test database. The source is a production database with full cataologs.
The normal restore from a bak file does not seem to work.
We dont need the full text catalogs in the new database, but cannot change settings in the source production database.
Is there a way to take a backup of the sql 2005 database without the full text cataologs being included ? , without changing setting in the source database beforehand ?
SQL Server 2000 SP3.
Prior to SP3 the recovery model was switched to simple during transfer (Copy object task) and changed back to the previouis setting after DTS was complete.
Nice thing because performance was increased and T-Log was keep small.
Now I assume that the recovery model is switched to bulk-logged causing the T-Log to explode, to be onest not in all my databases.
1.Is my interpretation regarding recovery model correct?
2.Does anybody knows the reason of this change?
Any suggestion is really appreciate.
Thank you very much - kind regards.
Hello,
I'm new to MS SQL Server I want to know which recovery model is good, Full or Bulk Logged as I'm doing full backup at 11:00 PM and diffential Backup at 12:30 PM and from 8:00 AM to 6:00 PM 15 min log backups.
Please guide me which recovery model should I choose.
Thanks

What would be the best Recovery Model for: a database which is 4 gig in size and imports via MSAccess queries and also stored procedures approximately 400,000 meg of data each month (and some other update queries are run against it) and it is also queried off of for totals on weekly basis?
The problem is that the SQL Server box only has 512 meg of memory and the tranlog on this database grows tremendously each import and when update queries are run against it. This tends to slow things down a bit on our other databases. We are getting a new SQL Server box but until then, what would be the best recovery model? I currently have it as Bulk-Logged and allow the tranlog to grow by 10% (with a base of 250 meg). The tranlog grows to up to 5-10 gig and in order to shrink it, I have to change the recovery model to Simple, and then back to Bulk-Logged in order to shrink it (I've tried all the dbcc shrinkdatabase, dbcc shrinkfile, dbcc showcontig, and dbcc checkdb commands as well as BACKUP LOG dbName WITH TRUNCACTE_ONLY and nothing will shrink it unless I change the recovery model to simple.)
I can't understand what is diff between simple & bulk-logged recovery
model
Hello, everyone:
There are some explanations on this topic from books and BOL. Could you offer the real experience? Thanks.

does the recovery model also change in a replication enviroment when you change a database from simple to full?

We are using a .bat script to restore several client dbs onto our sql server 2000 db. We want to set the client dbs from full recovery to simple. What command should I use in the .bat file to make this change?
.bat file ==
:: Second, restore data from SQL Server backup file to SQL server...
isql -E -S ao3ao3 -Q "RESTORE DATABASE CBSN FROM DISK = 'D:MARS_SYSDATAUPDATESCBSNCBSN.BAK' WITH MOVE 'MEDISUN_BCNV_Data' TO 'D:SQLDATACBSN_data.mdf', MOVE 'MEDISUN_BCNV_Log' TO 'D:SQLDATACBSN_log.ldf',REPLACE;"
We have a fairly large database that we use to store mom alerts and it stopped alerting as it's transaction log became full. I suggested to the owner of the database to set the simple recovery model so the log could automatically be truncated. However, it appears that the database is frequently reaching it's limit (of 3gb) and I'm having to set the limit even higher on a daily basis. Can anyone tell me why this is occuring? I understood that when the log file reaches 70% it should automatically shrink?
Kind Regards

Hello,I've follow problem - thing to consider.SQLServer 200 sp3a, ms win 2003 serverdb simple recoveryThere is a production database, wich is around 20gb big. Db is backedup each day completely, but it takes up to 30 minutes.Because there is a simple recovery model, there is no transaction logbackup (it fails anyway), and we do not have up-to-point recovery.I'm considering to switch to full recovery model, but ....The problem is, I do not want to affect performance (when the backup isrunning, database is hardly avalible).So my question will be: does the full recovery model, will be betterfor db performance (for acces and blocking db; means, does it will takeshorter?)Strategy will be (I hope ok) to back up during the week onlytransaction log (incremental), and once at the weekend, full databasebackup.Generaly, which one is better for performance?Which strategy will be the best, to keep performance at high level, butalso have the possibility to restore data (in case of emergency) fromthe newest possible backup.Thanks for helpMatik

What is the relationship between recovery model and transaction log? How does recovery model affect txn log file size?
How to decide which model should I use?
Thank you
In SQL 2005, sys.databases has a column named recovery_model that stores a code for the type of recovery model used by the database. Where is the recovery_model column in the SQL 2000 master database?
Thanks,

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.
View 6 Replies View RelatedGiven 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.
The SQL Server is running full recovery model but they would like it to be changed to simple while the data backup occurs then set back to full. Is there a way to do this in a stored procedure or is it all done via options ? Thanks

Hi All,
SQL newbie here. I just looked at my Job Activity monitor and found that my Transaction log backups are failing. I looked at the error and it read as follows:
Executing the query "BACKUP LOG [OperationsManager] TO DISK = N'D:\SQL\MSSQL.1\MSSQL\Backup\OperationsManager\OperationsManager_backup_200805061000.trn' WITH RETAINDAYS = 1, NOFORMAT, NOINIT, NAME = N'OperationsManager_backup_20080506100001', SKIP, REWIND, NOUNLOAD, STATS = 10
" failed with the following error: "The statement BACKUP LOG is not allowed while the recovery model is SIMPLE. Use BACKUP DATABASE or change the recovery model using ALTER DATABASE.
BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I read some of the posts regarding this error, but I am not sure how to do the steps. How do I change the recovery model? I am new to this so I have no clue how to do this.
Any help would be greatly appreciated.
Thank you.
How can I get the information that who has changed my SQL database recovery model ?

I hope you can help as I am really scratching my head on this one. I am pulling together an assessment of the Disaster Recovery readiness for an organisation I am working at. Part of the assessment I am doing is the recovery model of each of the databases.
I have scripts that are already pulling lots of data from 40+ servers and 500+ databases. However, I cannot seem to find anywhere within the MASTER or MSDB or the database itself where the Recovery Model flag is held. Obviously I can right click on the database and click properties and it is there, but I need to automate this task (as it will probably be a weekly assessment).
I have checked sysdatabases and almost every other table, but nothing obvious as to where this flag is.
Any ideas?
DB replication can set db recovery model to simple ,why db mirror can not db recovery model to simple.
DB mirror must be set to full recovery model.
As far as I know, whatever db mirror and db replication ,there is a log reader to read the log in the ldf file DB mirror and DB replication are almost the same principle to replicate the db to another db server.
