System Databases In Full Recovery Mode

Mar 6, 2006

Hi

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.

Plz help

Thanks

Db Backup Simple Vs. Full Recovery Mode

Feb 14, 2007

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?

Database Not In Full Recovery Mode On Both Partners Error:1465

Nov 15, 2006

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?

Recovery :: AG Databases Went Into Synchronizing / In Recovery After Upgrading To 2014

Sep 19, 2015

We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue

Recovery :: How To Know If DB Is In Log-truncate Mode

May 5, 2015

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?

Recovery Mode SIMPLE && SP2

Mar 12, 2007

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:

Changing To Simple Recovery Mode

Jun 26, 2002

Hi,

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)

Any info on this would be appreciated.

Thanks in advance

Jim

Database In Emergency Mode (bypass Recovery)

Nov 21, 2007

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.

Transaction Log Still Growing When In SIMPLE Recovery Mode

Dec 3, 2007

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?

DB Engine :: Simple Recovery Mode - Log Size Increases

Is this Possible, If database is in Simple recovery Mode and the ldf size gets increased?? .

mdf size :  159 GB (171,383,717,888 bytes)

My question is if the recovery model is in Simple Mode then why the log gets generated high.

SQL Tools :: In Simple Recovery Mode Can Do Live Differential Backup?

Jun 30, 2015

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.

Restore In Recovery Mode Fails Sometimes With [SQLSTATE 42000] (Error 3013)

May 26, 2008

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

The status of the 2 steps is :
1 Executed as user: BPOTESTREMEDY

SQL Server Admin 2014 :: Unable To Shrink Log On Simple Recovery Mode Database

Jul 27, 2015

I have a database that I am trying to recover space from, it consists mostly of unallocated space, but I can’t seem to get that unused space released.

Database size: 40,245.13 MB
DatafileMB: 38,063.63, DataAvailableMB: 37,085.15
LogfileMB: 2181.51

Sysfiles shows:
fileidgroupidsizemaxsizegrowthstatusperfname
114872144-112820SomeDB
202792332684354561010486420SomeDB_log

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

Each insert creates 93,576,664 rows.

Running dbcc SQLPerf(logspace) :
DBLogSize(MB)LogSpaceUsed(%)Status
SomeDB2181.534.204890

Running dbcc loginfo:
RecoveryUnitIdFileIdFileSizeStartOffsetFSeqNoStatusParityCreateLSN
0211437342728192602640
02114373427211437424645701280

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.

Simple Recovery And Full Backup

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.

Thanks

Ankith
