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.
One 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?
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.
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?
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.
On 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?
My trancaction log is 25GB and my database file is 39GB. I justswitched to the 'Simple' recovery model from the 'Full' recovery model.When if ever can I expect the size of the transaction log to reduce insize? Is there anything else that I should do to aide with thereduction?Thanks,Peter
We 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?
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 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?
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.
My understanding is that the log file is not supposed to grow if the database is under simple recovery mode.I am in a situation where the log grows if do any inserts that involve millions of rows.How do i make sure that it does not grow?
I am creating a database for an application through script. After the tables, views, and sp's are created, the database is populated with data. After all of this (and before the application is even run), the log file is about 700MB. If I shrink the database, it takes the log down to 1MB. The mdf file is about 165 MB before and after it has been shrunk.
I have two questions: 1. Is there something I should look for in my database scripts or is there a setting that could prevent this from being created so large.
2. Is there a script I can run in my sql code after the database has been created and populated to shrink it.
The DB is in simple recovery mode. There are no open transactions (used dbcc opentran).
The server is running SQL Server 2014 and the DB is in compatibility mode SQL Server 2008 (100). It was upgraded to 2014 a month or two ago.
I have tried to re-size the log to 100mb, but any way I have tried (none gave errors), the log file remains the same size. I have tied to shrink the log file (through the UI and via DBCC commands) without success; no errors, but also no change in file size.
I have checked Log Reuse Waits, just in case, and as expected it showed “NOTHING” (select log_reuse_wait_desc, name from sys.databases)
I tried running a checkpoint, but that did not allow any resize or shrink to work.
I have tied creating large transactions to move the used point in the log file, in case this was the issue. I did this by creating tables that I drop after large inserts. While it shows me that the log space % used increased, the log file still does not allow the space to be reduced.
The following is what I was using for the transactions to get the log used.
BEGIN TRAN select a.* into testtable from sysobjects a, sysobjects b, sysobjects c ROLLBACK TRAN
Do I just need to continue running large transactions until the log space used gets high enough to get the “end point” in the log to really move? Is there an easier way to accomplish this (I have several DBs that have the almost identical problem), what I am using moves the Log Space Percent Used about a percent on each execution.
One of the databases in our server is in recovery mode after a huge delete job (started as a job) did not complete ( I suspect due to lack of transaction log sapce.) the log file size is 120 GB.
Whenever the server restarted the recovery for this database starts.
After 20 hours, analysis done 100% and recovery done up to 76%. Then after the percentage of recovery done? went down to 16% and it is still running.
How can I get rid of this database without damaging the master database and other database in the same instance?
I dont mind to lose this database.
There are 4 user databases in this instance and msdb and the recovery mode database are not operational.(I cannot connect)
Last week I backed up my SQL Server by using BE 2012. I named the file "SQL Server BAK" which contained copies of my SQL Server databases. A few days ago I lost some part of my data due to accidental deletion. I backed it up, so I tried to restore the database from the .bkf file. The problem comes here, when I try to to restore my .bkf file, it becomes inaccessible.what causes this?
Hi there - can anyone advise on the following issue. We have recently performed some server side tracing on a particular SQL instance over 24hr period. We are now attempting to load these into a database for analysis. Here lies the problem.
When we are loading the profiler trace files (one at a time) into the database the transaction log is growing at an excessive rate. Even though the database is in SIMPLE mode.
We are loading the traces using the command:
INSERT INTO sqlTableToLoad SELECT * FROM ::fn_trace_gettable('MytraceFileName', DEFAULT)
Can anyone advise how we could possibly get round this issue as we're running out of space due to the transaction log.
We are doing restoring in a different data center and keep sending log backups and restore from there.Recently we want to bring a new volume to the sql server and move all databases to the new volume, then the problem comes, I did a test that I cannot simply change the drive letter, i.e. old disk letter x, new disk letter y, then I turn off all sql instances and move all databases(restoring status) to disk y, then get rid off disk x, resign x to disk y, so now new disk has old letter x now. then I continue the restore log against latest log backup, it returns the error.
Msg 3446, Level 16, State 2, Line 4 Primary log file is not available for database 'TestDB' (7:0). The log cannot be backed up. Msg 3013, Level 16, State 1, Line 4 RESTORE LOG is terminating abnormally.
Is there a way to do this? or SQL Server doesn't support this change.
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.
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.)
does the recovery model also change in a replication enviroment when you change a database from simple to full? regards Johan van der Wiel Johan.vanderWiel@getronics.com
