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
I have a database that is set to Full recovery model, I would like to switch to simple. I must perform some procedure before doing so? The size of the transaction log is very high in this database, I would like to decrease it before moving to simple, have a problem doing that?
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?
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?
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 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?

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)
Hi ,I have set up my database to be using "Simple" mode. This will not log anytxns ?I have got the err message saying the log file is full and i need to do atxn log backupi do not understand why , could anyone kindly advise ?tks & rdgs--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200510/1
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?
Something strange is happening to our SQL Server DB (2000). Thetempdb transaction log file continues to grow (quite slowly) for noapparent reason. We have it in simple mode, and I have tried a manualcheckpoint command and manual shrink (of the log file only). Thereare no unusual SQL's (large or small) going on. A "heavy hitter" wouldmake it grow fast, not 10 MB every 30 minutes or so. This server hasbeen in production for over a year with no similar issues to this.Anyone encounter a similar situation? This started (as far as we cantell) sometime yesterday. It is growing about 200 MB a day, and is upto 600 MB now, with all but 8 MB "used". For now we added space, butof course that is not a long term solution. The two "data" files(each had a 200 MB initial allocation) have never gone much above 100MB each used (they are each about 100 MB now and have been that wayfor several days, but have shrank and grown). There are about 30small to medium sized "regular" databases on this instance.Any help would be appreciated, especially if there is a way we can fixthis without bouncing the engine (I know, wishful thinking...). The OSis Win 2000, SP3. SQL Server is at 2000, SP 3a.THANKS IN ADVANCE!
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?
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.
I have a stored proc that runs through my databases doing transaction logs. Currently it uses database names but this keeps being changed as a database will be added without me knowing. Next thing the transaction log job is goosed.
I really need something along the lines of select db from sys???? where mode = 'Full'
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.
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.
I had my database in 6.5 which i upgraded to 7.0 using SQL Server upgrade wizard.Then I created full text catalog. When I say incremental population It gives me warning that You can create full text indexes but can not execute queries against it as the database is still in SQL server 6.5 mode.What is the reason behind this?
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?
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.
Pardon me and my ignorance for asking this question. I just want to understand the backup architecture more clearly. According to BOL (both in SQL 2k and SQL 2k5) in simple recovery mode trasaction log backup is not possible since the log is truncated on checkpoint which is true. Also we know that FULL backup backups both the db and transaction log as well.
My question is what happens when a database is in simple recovery mode and a full backup is done. since the tran log cannot be backed up does only the db backup is done when a full backup is done?. What exactly happens behind the scenarios?. Is it that only the active log gets backed up when a full backup is done in simple recovery mode?. I am trying to understand how a full backup in simple recovery mode behaves without contradicting the full backup architecture and that the veracity of the statement (both db and tran log backup in full backup mode) holds true for a simple recovery scenario.
MVPs/ MS Experts if you could Please explain it in detail, I would really appreciate it.
My source has 2.2 million of records. I'm performing the incremental load.In the lookup transformation i used the destination table for the reference using Full cache mode.For the first time package executed successfully but when i executed the package second time, Suddenly Package hangs while running.Than i truncate the data from the destination table and restart the SQL Server Services.After doing all this i executed package again and it worked but when i executed package second time, again package hangs up .I have 8GB RAM and i5 2.5 GHz Processor laptop.
I'm looking for a simple way of telling (inside a stored procedure) if I'mcurrently using MSDE or a full SQL server. Ideally, there is somepre-defined environment variable that won't cause me too much overhead. Thereason I'm doing this is because my system "rolls over" databases when itreaches the 2Gb limit with MSDE, but obviously I want to avoid this overheadif the user installs onto a full SQL server instance.ThanksRobin
Does anyone know what the commands would be? I am trying to create a job that puts a DB in simple mode then launches a reorg and re-index, then sets it back to full when it is complete. This way I can eliminate large transaction logs being created.
One of my programmers changed their database from full to Simple recovery. Saw that my job that backs up the Full Recovery mode databases failed, so I moved that database to my Simple database backup job plan and removed it from the Full Recovery job. I am unable to remove the db from the Transaction Log task on the Full Plan because when I try to edit that job "Databases with Simple Recovery will be excluded"
My transaction log backups are still failing 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.Just want to remove that database so my Full Recovery backup job does not try to back it up.
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 have reports in SharePoint integrated mode which are really slow when compared to native mode. I have been asked to research and give info on what exactly causes the delays.
Any articles which give me information as to what happens when a report is run from SharePoint server and where does it log.
There is a query which when executed in the grid mode(ctrl+d) takes approx 0.02 seconds(about 21,000 rows) But when I execute in the text mode, it takes about 0.40 seconds!! Why is this difference? Also, when the records from this table are read from a VB application, they are equally slow (as in the text mode!) Why is it so slow on the text mode & relatively faster in the grid mode? Has anyone got any idea on Firehose style cursor ?(which may speed up access of data in the VB application)
