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?
On SQL 2000, if I have a large transaction log for my database and I manage to fill it with a single large transaction but it is not set to autogrow, what happens?
I have several databases that perform daily backups. Ever since I installed SP2, the backup jobs are failing. The logs state that it's because the database recovery mode cannot be SIMPLE, but need to be either FULL or Bulk-Logged.
Can anyone tell me if this is true, and that I do have to change my recovery mode?
Here's the error:

What is the impact of changing the recovery mode of a database from Full to simple? The client I am at has set their database to full recovery mode, set their log files to grow automatically. But I don't think they have ever done a backup of their transaction log (it has grown to over 19Gig, where the data portion of the database is only around 400M).
What is the impact of truncating the transaction log now? After truncating it, i would like to shrink the file to a managable number and change the recovery mode to simple (they don't need transaction log backups)
When we do a full database backup manually, we are seeing the trn file reflect the current date/time, but we are not seeing the mdf reflect the new date/time. And we are not seeing the transaction log file decrease in size. the recovery mode is set to full, do we need to change to simple to see both the mdf being backup'ed?
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?
I have a small, ~10GB SQL 2008 R2 database, that was setup with simple recovery. We do full backup each night at midnight when no one is using the database. Is there any problems with doing differential backups during the day when users may be writing to the database? Could I even do hourly differential backups while users are using the database? I'm conflicted about switching over to full recovery mode and using transaction logs to have the ability restore data between backups. If I can do a couple daily differential backups while users are using the database during the day, in addition to our nightly full backups, than I live with simple recovery mode.
Wondering whether I can have following included in a script file:
1. set the current single user db from Full to Simple recovery mode. 2. Checkpoint and shrink the transaction log file (release all unused space) 3. set the current single user db from Simple recovery to Full recover mode.
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.
I have a database in production server with 3,5 GB of data file size and 10 GB log file size. This is very strange isn't it? The features of this database are:
SQL Server 2000 Recovery Model = Full Auto Update Statistics = Yes Torn page detection = Yes Auto create statistics = Yes Full database backup taken once daily. No log backup is taken.
So, I would like to apply some statregy to avoid the log file increase out of control. Can you give me your suggestions??? My free disk space is very low.
I measure PLE on my server and insert them every minute into a table. Now, when I look into the table I just dont know how to interpret the following data. I dont understand how is that possible. It's an sql server bug? or? How to interpret that data?
Im in the process of setting up logshipping on sqlserver 2005 enterprise edition. My scenario is like this: My Avg size of my tlog is 500MB and im planning to set the log shipping at 30mins interval(ie backup job schedule,Copy,restore job schedule).But at some part of the day the Tlog suddenly increases up to 1.5GB - 2 GB .So i wanted to know, wht if that 1.5GB-2GB tlog file is unable to get backed up,copy and restore at 30mins interval?.How to deal with this kind of issues where the size of tlogs are increased suddenly.I cannot do it at15mins interval due to some network restrictions at my office.
i have One more doubt about the setting on Logshipping screen: Now let us suppose my settting on log shipping screen 'Alert if no restore occurs within' is set to '180mins', then does this setting mean that the restore job will keep on looking for the copied file in the folder on secondary for next 90mins and if its not able to find any, it will generate an alert after 90mins ??? or it will generate an error if its nt able to find any copied file after the first restore job execution.??? in the same way,
We have 2 SQL Server 2k5 servers running the same build - 9.0.2047 . When I backup any database from one server and attempt to restore it to the other, the log file generally increases by 100 fold. It errors out after I try to restore a 100MB db and it tries to create a 9.8GB log file. This happens both when I use the GUI to restore and when I restore from a T-SQL script. What am I doing wrong?
We have 300+ databases on one sinlge server (SQL 2005). If I need to change recovery mode from full to simple for all of them, is there any way to do so? Please advice.
I have a db running under simple recovery mode. I am really pressed at disk space, and we have a long running script that keeps failing with "no space left on the device" error. I noticed the log file is very large. I plan to set the max log file size but at the same time I want to know that the database is in the log-truncate mode - perhaps from the database itself. Is there any metadata that could tell me this?
By default, distribution database is set to simple recovery mode. Why ? Should this be changed to full ? how often should transaction logs be taken ? What is the recommendation ?
What are the pros and cons of putting the system databases in full recovery mode I am asked by my manager to keep everything simple and uniform.We have all the user databases in Full recovery mode and he wants all the system databases as well to be full recovery mode. I would like to get the points where in i can argue that, there is no point in having the system databases in full recovery mode.Unfortunately i dont see anything related to this in BOL or internet.
1st question I have to ask is: Is Emergency Mode the same as Bypass Recovery Mode?
2nd: I have a SQL2005 Database that was suspect this morning. I put the database in Emergency Mode: alter database {dbname} set emergency.
I did a dbcc checkdb on the database and found some corrupt indexes. I attempted to do a dbreindex on the table and got the error: Could not run BEGIN TRANSACTION in database '{dbname}' because the database is in bypass recovery mode.
How can I put the database in single_user mode and to a point where I can reindex the 1 table that is causing the problems. I would even be willing to drop the indexes and re-create.
Any suggestions or help would be appreciated! Thanks in advance.
Which system table is this information held in, i restored over 100 databases and want all of them to be simple mode. I manually set it each time after each restore, but i want to confirm but i cannot find the sys table to do a select on. I looked at sys.sysdatabases
We have a SQL Server 7.0 database running with trunc. log on chkpt andselect into/bulkcopy checked and need to develop a backup strategy.One of our DBAs insists that since the transaction log is beingtruncated, we can't do a hot backup (a FULL backup in multiuser mode)because if a transaction comes through during the backup it will leavethe backup in an inconsistent state. I'm skeptical, but I don't knowhow SQL Server 7 avoids this problem.If SQL 7 is not truncating the transaction log, it uses thetransaction log to roll forward changes that occurred during thebackup. Obviously if it's truncating the log it must have some way toapply these transactions anyway (such as not doing a checkpoint duringthe backup, backing up the log at each checkpoint, etc.).Can anyone confirm that a hot backup will be valid when trunc. log onchkpt is checked? Does anyone know how SQL 7 accomplishes this?Thanks!James
I 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?
I put the database in emergency mode, then I executed Checkdb, it shows no errors. The database status is still EMERGENCY and when I try to bring it online, it says he database is in single-user mode, and a user is currently connected to it. There is one processes which is accessing the database, i try to kill it, but it is not going. I am not able to set database to multi user.
i've change the database log file from E drive to Drive due to insufficient space.without attaching the log file i've shutdown the sytem. becz it's gone in hand mode.post resuming its showing recovery pending.i'm unable to get online db.
Hi, I run 2 steps viz with NORECOVERY and with RECOVERY in sequence as SQP jobs. The 2nd step fails some times. When it starts failing, I run full backup of the production server again and the 2nd step starts succeding. Unless I run the full backup the 2nd step keeps on failing.
What are the conditions which generate for [SQLSTATE 42000] (Error 3013) and how to tackle this problem.?
The 2 steps are :- 1.RESTORE DATABASE ARSYSTEM FROM DISK = 'E:SQL backup from productionsql_full_backup' WITH Replace , MOVE 'arsystem' TO 'd:ardataarsystem.mdf' , MOVE 'arsystem_log' TO 'D:ARLOGARsystem' , NORECOVERY GO
2.RESTORE DATABASE ARSYSTEM FROM DISK = 'E:SQL backup from productionSQL daily diff back up' WITH Recovery
