Can We Pause Log Shipping, Bring Primary Db To Simple Recovery Model And Then Back To Full R Model?
Apr 25, 2008
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

Recovery Model To Simple
Jan 18, 2008We 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;"
Simple Recovery Model
Jul 31, 2006We 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

Mirroring :: Why DB Mirror Cannot Set DB Recovery Model To Simple
May 2, 2015DB 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.
Switch Simple To Full Recovery Model
Jun 18, 2007I 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 ?

Log Truncation In The Simple Recovery Model - Can You Help My Understanding Of It Please
May 16, 2007On SQL 2000 or SQL20005 will a database's log file automatically be truncated if the database is on simple recovery model?
The reason I ask is that we have a database (simple recovery) that keeps growing its logfile each weekend which causes disc space problems.
I am kinda new to SS but from the reading in BoL I've done was under the impression that for simple recovery model log records are only needed until the transaction has been written to disc and committed, and that SS will handle truncating obsolete records from the log where necessary.
I'm doing DBCC SQLPERF(logspace) which shows this first thing on a Monday morning:
Database Name Log Size (MB) Log Space Used (%)
-------------- --------------- ---------------------
myDB 4841.93 99.19465
Note the size of the log file - the data file is only 700MB!
Issuing a DBCC OPENTRAN doesn't show any open transactions, and a CHECKPOINT doesn't do anything to reduce the log space used (which if there were dirty records in the log still not written to disc this ought to do shouldn't it?).
The database is only written to as a replication subscriber.
Any suggestions what would be causing the log file to fill up?
At the moment I'm resorting to BACKUP LOG myDB WITH TRUNCATE_ONLY and considering scheduling this as an hourly job over the weekend - any reasons why this could be a bad idea?
Many thanks,
Moff
Backup Of Ldf File In Simple Recovery Model
Mar 20, 2008
Hello,
I have a question regarding the backup for the database in Simple Recovery Model.
In this Model, I know we can restore only to the last full backup or can use differential
Backup, if implemented as a part of backup.
But my point of confusion is about the backup of '.ldf' file, should those file should be backed up in the
Maintenance Plan, if yes does it help in reducing the size of Log file?
Do we need the backup of '.ldf' in phase of Restoring?
As I mention my database has Simple Recovery Model, but the size of log file is around 20GB,
Could not understand why as in this Model, normally it automatically truncate the Log file?
Help me to clear my these doubts,
thanks,

View 5 Replies View RelatedSimple Recovery Model Database - Huge Log File
Nov 3, 2015Have 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.
SQL Server 2008 :: Log File Management In Simple Recovery Model
Sep 15, 2015One of our database is in simple recovery model, and usually generating more than 220 GB log file (.ldf) every week. We are shrinking log file many times to release the space.
But as its not advisable I am looking for any other options. I suggested to change the recovery model to Full and start T-log backup, but client dont want to change recovery model.
Is there any way to manage Log file of Simple recovery model to maintain disk space?
Will full backup truncate log file ?
Simple Or Bulk Logged Recovery Model For Fastest Import ?
Dec 21, 2006We have a sql 2005 x64 database (datawarehouse related), essentially a work area for us, that we truncate and re-populate via BCP weekly. (We don't backup the database at all) . From the perspective of data-import speed what is the best recovery model to use: Bulk-Logged or Simple? (I have read sql 2005 BOL and don't find it partcularly clear on this point.)

P.S. Anyone know of an article listing "best practices" for high-speed data import?

Jul 23, 2005Hi All,I have a 2MB database set to SIMPLE recovery. This database is usedonly to generate new keys to web users. It has two columns - UID andLASTDATE. The UID column is only updated when users log in or log out(INSERT & DELETE). The LASTDATE column is updated every time theyswitch between pages.Please don't ask for the reason why we do it this way, it just IS.The maximum amount of rows in this table at any given time is about2000. There is a non-clustered index on the UID column.My problem is that all throughout the day I have constant blocks by theWRITELOG waittype. I know my disk I/O is very slow (will be upgradedsoon) but this is the only database on which these blocks occur. Whatis writing to the transaction log if I have the DB set for SIMPLErecovery?Thanks,Josh

View 3 Replies View RelatedDTS - Recovery Model
Jan 31, 2003SQL 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.

Best Recovery Model
Jan 11, 2006What 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.)

Recovery Model Problem; Db Properities
Feb 16, 2006Hello,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

Model Database Recovery Planning
Mar 29, 2007I 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?

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 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.
