How To Back Up The Transaction Log For The Database?
Feb 8, 2001
Hi all,
I'm getting the following error message in NT event view:
Error: 9002, Severity: 17, State: 2
The log file for database 'db_sys' is full. Back up the transaction log for the database to free up some log space.
But I don't know how to back up the transaction log for the database.
Do I need TRUNCTE LOG (in E.M) to free up some log space?
I only know back up all the database using ALL TASKS -> BACKUP DATABASE in E.M. Please help me. Thanks in advance.

I have a Development database and I want to roll it back to Monday morning. I backed up the database and used the command:
RESTORE DATABASE ITTEST
FROM ITTEST20040203
WITH NORECOVERY
GO
RESTORE LOG MyNwind
FROM ITTEST20040203
WITH RECOVERY, STOPAT = 'FEBRUARY 2, 2004 09:00 AM'
GO
The transaction logs have never been truncated.
But it does not seem to have worked. It this the best way to do a roll back the database or have I missed out something.
thanks.

We had a siutation last night in our production environment that forced us to revert back to an earlier version of the database (before a major code rollout that failed). After restoring the days full backup (with NORECOVERY), and then restoring a DIFF backup (FULL RECOVERY and had checked Preserve Replication Settings)...the transaction replication failed.
Message #1
The replication agent has been successfully started. See the Replication Monitor for more information.

I've tried reinitializing the publication/subscription and while that took brand new snapshots and copied it over to the replicated data server, it did not fix the problem.I read from a different post that I could try running "sp_replrestart" but that ran for about a half an hour and didn't appear to do anything but fill up our log files...did I not wait long enough?
The only thing I know to do at this point is to drop the publication on the production server and rebuild it completely (and with all the tables we're replicating that would take quite a bit of time.

New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

I have a stored procedure that calls another stored procedure with thefirst stored procedure opening a transaction:BEGINSET XACT_ABORT ONBEGIN TRANSACTIONdoes various updates/insertscalls 2nd stored procedure to proccess updates/inserts common to manyother stored proceduresdoes more various updates/insertscommitENDThe problem I'm having is that within the 2nd stored procedure is thatif it encounters an error, it does not roll back the entiretransaction and I finish up with missing records in the database. Amusing this in the 2nd stored procedure:if(@TypeId1 = @TypeId2 and @Line1 <'' and @Line2 <'')beginRAISERROR('error message', 16, 1)RETURNendWhat could the problem be? From what I've read, it seems as thoughyou can't have an open transaction within one sp that calls another spand it maintains the same transactoin? Is this corrrect?I tired the following too, and I still couldn't get it to work. Anyideas anyone?************ sp 1 ***********Declare @AddressError char(3)SET XACT_ABORT ONBEGIN TRANSACTIONexec Sp2@AddressError OUTPUT,@variable1,@variable2,etc. etc************** sp 2 *****************@AddressError char(3) OUTPUT,if(@TypeId1 = @TypeId2 and @Line1 <'' and @Line2 <'')beginRAISERROR('error message', 16, 1)RETURNendSET XACT_ABORT ONBEGIN TRANSACTIONprocess updates/insertsSet @AddressError = 'no'Commit******** back to sp 1************If @AddressError <'no'BEGINrollback transactionENDcontinue doing updates/insertscommit

Hi,
I have a case where I read from SQL Server DB and write to a flat file.
I have one Data Flow Task inside which I have a OLEDB source component that feeds rows to a script component that writes to a flat file. I have set the txn attributes for the container to "Required" and "Read committed" . But I find that rows are written to flat file even when I throw an exception from my script component. Question is how do I prevent rows from being written to the flat file if error/exception happens. I want the whole process to be in a single transaction.
Thanks

The following transaction runs, then reverts back after 10 mins.
begin Tran [UpdateSundays]
update ScanAssetInformation with (rowlock)
set BusinessDate = dateadd(day,-2,BusinessDate)
where datepart(weekday,BusinessDate) = 1
commit tran [UpdateSundays]
begin Tran [UpdateSaturdays]
update ScanAssetInformation with (rowlock)
set BusinessDate = dateadd(day,-1,BusinessDate)
where datepart(weekday,BusinessDate) = 7
commit tran [UpdateSaturdays]

hi,
i want to create a disaster recovery site, to which i can fail over (not automatically),
and also to have the option to return the database to a point in time?
for example,
if my principal server fails in 17:00,
i want to have the option to make the mirror server available for users from 17:00 (or at least close to that time),
and also to be able the return to the data from 16:00 (in the mirror site).
Is it possible, and what is the best way to do it?
Thanks.

hi, I would like to know the correct reaction for a crash in both senarios.
First senario,
I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.
Best regards
Ahmed

I have a page that runs a transaction correctly after a button click.
I want to allow someone to click a button that rolls back the transaction, after the transaction runs on the first button click.
I can also successfully roll back within the first button click.
I'm getting a NullReference error when trying to access SqlTransaction.Rollback() outside the button click.
If SqlTransaction.Commit() completes without error can SqlTransaction.Rollback() be called after?
I tried making 'trans' a more global variable and it still gave me the error.
Button Click 1:
Dim trans As SqlTransaction
trans = connection.BeginTransaction()
try
'run SQL Statement
trans.Commit()
Catch e As Exception
trans.Rollback()
throw e
end try
Button Click 2:
trans.Rollback()

I am confused about save transaction in the below scenario :
begin transaction
save transaction t1
delete from #t1
save transaction t2
begin try
delete from #t2
[Code] ....
If there is error after delete #t2 , transaction t1 is rolled back. But i am not able to understand why i am getting error in the statement 'rollback transaction t2' . I am getting error as 'Cannot roll back t2. No transaction or savepoint of that name was found.'. but save point t2 is mentioned in the code.

Hi,
I followed Remus' post about not doing 'fire and forget'.
I have two queues, ProcessingSendQueue and ProcessingReceiveQueue.
Once i receive from ProcessingReceiveQueue, activation SP gets called on ProcessingSendQueue and ends conversation.
However,if I then get an exception, the action of the activation SP ( ie the ending of the conversation ) does not get rolled back... is this possible? I would have thought that the action of the activation SP would get rolled back too.
My ProcessingSendQueue activation SP is as follows:
ALTER PROCEDURE [dbo].[ProcessingSendQueue_AP]
AS
BEGIN
DECLARE @dh UNIQUEIDENTIFIER;
DECLARE @message_type SYSNAME;
DECLARE @message_body NVARCHAR(4000);
RECEIVE @dh = [conversation_handle], @message_type = [message_type_name], @message_body = CAST([message_body] AS NVARCHAR(4000))
FROM [ProcessingSendQueue];
IF @dh IS NOT NULL
BEGIN
IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
BEGIN
RAISERROR (N'Received error %s from service [ProcessingReceiveQueue]', 10, 1, @message_body) WITH LOG;
END
END CONVERSATION @dh;
END
END

Goofed up and ran an update query. It messed up all the data in a single table. I'm trying not to restore the table from a previous backup since the backup is more than 20 GB. It's going to take forever to restore it. Any advice would be much appreciated!
Thanks!
Charles.

We have a high volume database with 1000's of users and 1000's of procs. Our application enforces a 20 second timeout on all connections.
We can't adjust the 20 seconds - this is a business rule.
It sometimes happens that a proc does not complete within 20 seconds and then times out halfway though. This causes data inconsistency where 50% of the code was saved to the DB and 50% was not - seeing that a stored proc is not transactional and therefor does not roll back the code.
We can't put the code in a TRANSACTION in order to roll back when a time out occurs, because this causes exclusive locks on the tables.
So I guess my question is:
Is it possible to undo/rollback all the code in a proc when a timeout occurs - without using a TRANSACTION? And if a TRANSACTION is the only way - how do I avoid the exclusive lock and blocks?

I'm having a problem with a Maintenance Plan created for SQL Server 2005 using Microsoft SQL Server Management Studio. See version information at the bottom of this post.
I have a Maintenance Plan using the "Back Up Database Task" that is set to perform a "Full" back up of "All Databases" on the local server. However, it appears that the list of "All databases" are hard-coded to be those databases that were available at the time the task was created. It seems any newly created databases don't appear to be in the list. If I attempt to edit the task and select the "These databases:" option, the newly created databases aren't even in the list.
Is there some way to have the task refresh the list of the databases available for backup? Ideally, I'd like any newly created databases to get backed up automatically without having to modify the task.
Thanks for your help,
Jonathan.

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick

Can somebody tell me how can I back up database to a different server from Enterprise Manager or any syntax?

I had to transfer my database from one server to another. Both are running SQL 2000. I backed the database up and moved it to the new server however when I try to do a restore I get the following message:
The media set for database "xxx' has 2 family members but only 1 are provided. RESTORE DATABASE is terminating abnormally.
I did some searching and found a couple of posts that mentioned something about the back up including 2 files.
My problem is that the machine I backed this up from crashed when it was shut down and would not reboot so all of the data and the original database do not exist. Is there any hope of restoring this database. It is pretty critical.
Thanks,
Melissa :-)
