Backing Up Trans Log Of System Dbs

Feb 20, 2007

Guys,

Should the transaction log of the system databases be backed up and if so, how often should this be done, generally?

Currently, we are backing up the system databases daily. The transaction log of the system databases, however, is not backed up.

Recently, I was wondering what exactly could happen, which would imply that we need to back up the transaction log of the system databases.

As far as I understand, 'msdb' contains things like jobs, dts. As such, if no jobs/dts are added in the middle of the day, there is no need to back up the trans log of this db - there could even be no reason, in such case, to back this db up at all!

'master' db would change if we add/modify objects/properties and so on ... so unless many changes are made, no need for backing up its trans log.

Having said that, could anyone enlighten me as to whether it is necessary to back up the transaction log of the system dbs and/or what it depends on and/or when it is suggested to do so?


Thanks you

Backing Up Trans Logs To Win2000 Server

Jul 31, 2002

I have my SQL7 server running on NT4 server. Currently the transaction log backups are on the same server but I want to back these up to a Win2000
server in another building. When creating a Backup Device in Enterprise Manager on the NT server it cannot see the drive but not the folder I have created on the Win2000 server, even though I have shared this folder out and set the permissions. Any help would be appreciated.. Thanks

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

Aug 21, 2006

I have created a windows library control that accesses a local sql database

I tried the following strings for connecting

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"



I am not running the webpage in a virtual directory but in

C:Inetpubwwwrootusercontrol

and I have a simple index.html that tries to read from an sql db but throws

the error

System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,

etc etc

The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted


I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security

I think that a windows form connecting to a sql database running in a webpage should be simple

to configure what am I missing?

Trans Rep Will Not Replicate

Jun 18, 2001

I have set up a simple trans rep from a server in the office to the web. both servers are NT4sp6aSQL 7.0. Tables only.

The publication and distribution db are on the server at the office, and there is a full time connection through the firewall.

The initialization and first replication works perfectly, but after that, there is a message from the snapshot agent that "no subscriptions needed initialization", the logreader says thare are no replicated transactions and the Distribution agent says there are no replicated transactions. What am I missing?

Thanks in advance

How To Move Trans Log

Does anyone know how to move the transaction log(s) of a LIVE database to a new location. I must move the log of a database to a new mirrored drive without any disruption to users. I cannot take the database offline or use the sp_detach_db stored procedure. Your inputs are much appreciated!

** Trans Log Won't Truncate **

Oct 16, 2000

SQL7:

I have a 300MB db, and a transaction log near 1.3GB. Upon notification, I backed up the db log with truncate_only - no luck getting it smaller. Later, tried backup with no_log ( assuming the o/s was full - no diff)

I tried shinkfile (logfile,truncateonly) and no luck.

I tried dbcc opentrans to see if any pending trans. The db looks fine with dbcc checkdb. I managed to free up a mere 50MB. I checked the permissions on the db, and added backup db, and backup log in the db permissions for the user logged in (also tried this with sa)

I am unable to free up the space to the os. Can I somehow rid the log file and start off with a fresh log file? I need this space. As a patch I moved the log to a larger filesystem as a temporarily fix.

start/stop SQL- nothing? reboot -nothing? I played with waiting game. This log does not want to release space. The log grew from data loads.

Question1: Suggestions how to truncate this log? The contents are not really impt, but the space is.

Question2: Can I add another logfile, then use EMPTYFILE to transfer the contents to the newly added log file, then REMOVE The original logfile? In theory does this make sense?

Thanks,
Jason

Trans Log Confusion

Nov 5, 2002

:confused:

Here's my situation (SQL2K)

We have a testing database we're using to convert large amounts of data from 1 system to another. We might process 5-6 million records, but don't care about being able to recover point-in-time.

I set recovery mode to simple, do a full backup every night. I keep getting large transaction logs. I manually run Shrink Database when I realize the logs are big

What can I do to prevent the logs from getting big in the first place ?? Can I prevent logging from happening ?

I keep reading various books and BOL, but I guess I don't quite "get it" yet ......

Any plain spoken, detailed suggestions would be very appreciated .... thanks in advance.

Begin Trans

Nov 15, 2004

If you are set up for AutoCommit why would you or should you set a explicit transaction? I have noticed that in some called stored procudures from a "container" stored procedure. (Hope I got that right) that in the called stored procedure a Begin tran is used. Can anyone help with the why and what fors? It seems to me that you want to let SQL Server handle this becuase of the danger of leaving out a Commit or Rollback? But thats me. I may be very wrong? Thanks.

DBCC To Trans Log

Aug 22, 2005

Hi,
I was just wondering, if I have a DB for log shipping, and change the recovery model to bulk-insert before I do a dbreindex, does the log still grow as big as the full recovery model? as in when the DB in bulk-insert model, will dbreindex still writes to the log? What i'm trying to do is try to make the log files smaller for log ship when i'm doing the db reindexing job.
Thanks.

Cycling Thru Trans-SQL

Aug 31, 2005

I’m really scratching my head with this Transact-SQL, say you wanted to cycle through a set of rows, then perform an operation on each row, so in VB/DAO it might look like this:
Dim rsTables As Recordset, rsIndex As Recordset
Set rsTables = dbSource.OpenRecordset("SELECT * FROM INFORMATION_SCHEMA.tables")
Do While rsTables.EOF
Set rsIndex = dbSource.OpenRecordset("Select * From SysIndexes Where Name = '" & rsTables!Table_Name & "'")
DoSomethingToIndex rsIndex!Name
rsTables.MoveNext
Loop

How can you do this cycling with Trans-SQL?

Disable Trans. Replication - HELP!

Mar 20, 2000

Hi,

I am trying to disable transactional replication, but am having some problems. I used the wizard, however, it has taken 7 hours so far and is still not done. SQL Server (7.0) is showing the connection as runnable but it seems as if nothing is being removed. Am I missing something? Should I have done something else before running the wizard? I can't even kill the SPID.

Can anyone help or offer some advice?

Thanks in advance...

SQL 2000 Trans Logs Too Big

Aug 10, 2001

We're running Lawson software on our SQL 2000 box. We're using Veritas
Backup Exec to back up the databases to tape. I'm also using a Maint
Plan for an extra backup (kinda redundant, but I need the practice at
all this). I just added transaction logs to the maint plan (so I
thought) but I only see a log for 1 of the 3 databases.

Also, my trans log file is 11 gig. I thought backing up the trans logs
would get the trans to delete afterwards (databases are recovery
model=full). Can anyone point a newbie in the right direction.
Fortunately it's not in production yet, and we haven't had any disasters
(yet).

Can I Shrink Trans Log Even If Doing Log-shipping?

May 3, 2007

I have a 2000 DB which is log-shipping to another server. The log has grown huge and needs to be made smaller. Can I use DBCC SHRINKFILE without damaging the log-shipping? I know that truncating the log destroys log-shipping, but shrinking should logically not cause any harm. Do you know? Is there a better way to reduce the size of the log file without damaging log-shipping??



Thanks!

How Do I Shrink The Log Of A DB Used In Trans Replication?

May 2, 2006

I am sure this has been asked multiple times before, but I have a DB (SQL 2K) that is involved in transactional replication. The log periodically grows to a seriously big size. How can I shrink it without damaging replication? I have opened SSIS (SQL 2005 is the subscriber) and tried to shrink the file, but to no avail. It reckons I could shrink it to 0MB, but I feel this would throw out replication.

Any help appreciated.

Trans Replication - Filtering && Deleting

Jul 14, 2003

Here's what I'm trying to do (Maybe there's a better way)

I'm using Transaction Replication and a pull subscription to get all the transactions from the ORDERS table within the last year from Server_A to Server_B. I filter the rows "WHERE (ORDR_DATE > (GETDATE()) - 365)"

That works fine, BUT, the old rows in the subscriber's ORDERS table do not get deleted, so I have all the records for the last year, plus the older records that I don't want any more. Do I need another step some where that does a "Delete WHERE (ORDR_DATE < (GETDATE()) - 365)" But then I have to maintain my date logic in more than 1 place if I ever want to change it.

Any suggestions, thoughts, improvements will be appreciated .... Thanks a lot

Temporarily Avoiding Writing Into Trans Log

Mar 9, 2007

Guys,

Is there a way to temporarily disable logging into the transaction log.

In our system, we perform purging of our database every night, where the purging consists of 2 steps:

1. For each table, insert the data, to be deleted, into a corresponding "purged" table, to remain there for one day only.

2. For each table, delete the unnecessary data (i.e. same data stored in purged tables in step 1)

During these 2 steps, the transaction log grows, and since we perform the transactional log back up, the back up at that time is huge. We are running a bit low on the hard disk space and I'd like to disable logging into the transaction log when these operations are performed.

I really don't care about being able to recover this data.

I thought that one option is to set the database to simple recovery, then perform the purging of the database, and then change back to full.

However, I think that trans log can grow even if recovery model is simple [although you won't be able to retrieve any changes].

So, is there a way to delete a portion of a table [or insert into it] so that no data is written to a transaction log (I know that we can use TRUNCATE if we need to remove whole table without logging)?


Thanks a lot
