Restoring Tran Logs To Standby
Jan 22, 2001
I have recently implemented a backup solution that keeps our standby server up-to-date with nightly database backup and restores. Ironed out all the problems with syslogins and orphan users. It's been working very well over the past few weeks.
On the production server we do hourly tran log dumps every hour between 8am and 10pm. I would like to implement some form of "log shipping" to bring the window of vulnerability down to 1 hour. By making some alterations to my current process I been able to incorporate the hourly log dumps in the same process.
However, when I try to restore the log on the standby servre I get the following message,
Server: Msg 4305, Level 16, State 1, Line 1
Specified file 'HODB1SQLBACKUPRace_Prd_T_dump.200101231513' is out of sequence. Current time stamp is Jan 23 2001 2:01PM while dump was from Jan 23 2001 3:01PM.
After a bit of investigation I found the dumptrdate field in the sysdatabases table and it was set to Jan 23 2001 14:01. After updating this field to Jan 23 2001 14:01, I ran the load command again but received the same error message.
Is there something else that needs updating on the standby server? Is what I'm trying to do possible in 6.5? Any help or ideas would be greatly appreciated.
Thanks

What is the advantage of taking frequent tran log backups (say every 30mins) as opposed to once a day? Say, I backup data and tran log once every night and I lost a table at 10:00am next day. Can't I recover the database to the point in time by restoring the previous night's backup and then applying the transaction log from previous night and then applying the transaction log (to the point int time) that you just dumped when the mishap was reported to you?
Thanks

I noticed our log files are getting way too big. I found that a previous
SQL guy had set up the following scheduled job with the TSQL statement:
BACKUP LOG DEV TO DevDailyTranLog with noinit
This runs every 20 minutes.
There's also a Maint Plan to do a Complete backup every night and a
Transaction Backup every hour (could be set to 20 min)
Why do you suppose the BACKUP LOG job exists ? If the maint plan were
set to backup transaction every 20 min, wouldn't the 2 jobs be
duplicating each other ?
Also, I notice that the Tran Logs specified in the database properties
seem awfully big (4 gig), shouldn't they automatically be truncated when
the daily full backup occurs ? (full recovery model)
Feel free to call me and straighten me out or to get more info.

I have been asked to implement a Warm Standby using Transaction Logs on our main SQL Database - Version 6.5.
Can anyone give assistance regarding scripts, etc., which control the process.
Any assistance is much appreciated.

We're planning to implement log shipping on our databases, and I have been toiling with it all weekend trying to get it to work on some test databases. The result is the same whether I do it via the wizard or manually via T-SQL.
I am using 3 servers, all SQL Server 2005 Standard SP1. All 3 SQL Servers are configured identically.
When I setup log shipping, it initializes with no problems. When it processes the first tran log file, it restores it with no problem. Every successive log file thereafter is not restored. No errors are generated. The only outright indication of a problem is that the monitor server shows that there has not been a recent restore.
The backup and copy both suceed. The restore claims to suceed. If I review the job history for each step, it says that it skipped the log file and then reports that it did not fina any log files to restore.
Message
2006-11-06 05:00:01.92 Skipped log backup file. Secondary DB: 'MyDemo', File: 'D:MSSQLBackupMyDemoMyDemo_20061106115619.trn'
Message
2006-11-06 05:00:01.95 Could not find a log backup file that could be applied to secondary database 'MyDemo'.
2006-11-06 05:00:01.96 The restore operation was successful. Secondary Database: 'MyDemo', Number of log backup files restored: 0
Any ideas or suggestions?

Can anyone direct me to a code that would automatically apply transaction logs to a DB in the standby server? We have a process that dumps the transaction log backup from the primary server into the backup server every hour on the hour, but I need to apply that transaction log as soon as it is in the standby server.
I am sure someone will ask, why not do transactional replication or log shipping? My answer to that is I have yet to learn how to setup replication between servers. I need to get our backup server up and running in the next few days.
Thanks in advance for your help.

Has anyone been able to successfully delete old backup files(*.bak) and tran logs (*.trn) TOGETHER using maintenance plan cleanup task in SQL 2005 SP2.
this is transact sql running in the back ground.
EXECUTE master.dbo.xp_delete_file 0,N'F:MSSQL.2MSSQLBackupibmdir',N'"bak" & "trn"',N'2007-03-26T22:21:14',1
This DOESNT WORK.
It works if I just try to delete only one of the things ie trn or bak files.
EXECUTE master.dbo.xp_delete_file 0,N'F:MSSQL.2MSSQLBackupibmdir',N'bak',N'2007-03-26T22:21:14',1
But is there a way to delete both bak and trn files using one task ?

I'm trying to configure log shipping When I retore the full disk dump of my databaseto my standby server, I need to be able to go in and drop and recreate several user logins(so they can do reports, read-only).
Once I do this though, I will be unable to restore T-logs, right?
Anyone know a way to get it back into a read only state and able to accept T-log restores? Thanks.

Hi all,
I am restoring database from Transaction Logs. I followed all the steps
mentioned in the book. Just before the last step there are three options
1. Leave Database Operational. No Additional Logs can be Restored.
2. Leave Database Nonoperational But Able to Restore Additional
Transaction Logs.
3. Leave Database Read_Only And Able To Restore Additional Transaction Logs.
Option 2 and 3 aresupposed to set on the NORECOVERY flag.
I tried both options 2, and 3 , But still got messages that I did not
specify WITH NORECOVERY or WITH STANDBY.
Can anyone please tell me what I am doing wrong?
Thanks in Advance.

Restart the restore sequence, specifying WITH NORECOVERY or WITH STANDBY for all but the final step. RESTORE LOG is terminating abnormally.
Can someone please show me how to properly restore a set of backup logs with specifying the required recovery option?

I have scheduled a database backup at 9 pm and 5 Transaction Log backups. The transaction Log backups happen at 11 am, 1 pm, 3 pm and 5 pm (device does not get initialized) and one at 11 pm where i initialize the backup device. now i have another server with the same database on it. I restore these backups on to this server by simple copying the files and then doing Restore ...From Device...Add file...option. I am able to restore the DB backup but when i try to restore the log backups it get the error msg -
'Specified file 'G:...' is out of sequence. current time stamp is Feb 9 2000 3:54 pm while dump was from Feb 9 2000 3 pm.'
When i am restoring the logs i start from the 1st backup buyt still i get this error. Can someone pls let me know what the problem is and how to resolve it. Thanks.

Hey all,
Just went through migrating to SQL 2005 as well and we have a need to apply log shipping between SQL 2000 and SQL 2005. Well not shipping per say in the automated fashion that SQL 2005 offers but rather we need to apply SQL 2000 transaction logs to a SQL 2005 instance. Though the database is still in SQL 2000 version 80 and the secondary database needs to be available in read only. (STANDBY MODE)
When I attempt to restore either a FULL backup or transaction log I get the error:
RESTORE DATABASE is terminating abnormally. This backup cannot be restored using WITH STANDBY because a database upgrade is needed. Reissue the RESTORE without WITH STANDBY
The only way I could restore the FULL was by using the WITH RECOVERY OR NORECOVERY option during the restore process. The issue with this is I need the database in standby by mode in order to continue to append transaction logs.
Anybody have any thoughts how I might be able to get around this?
Thanks
Eric

I've been reading a million and one posts on replication
My scenario is that i have a live SQL 2000 server. In a DR invokation, i'e i've lost my live sever, i want to be able to access the same data at the DR (SQL 2000) site and have it accessable to the users. DR server has a different name to the live box.
Replicate
Master
CRMDatabase
Data changes all the time but can have hourly replication of transaction logs for this example. I've currently researched a sp called update logons but this has to be fed each account name to enable them on the new server. There must be a way to activate all CRMDatabase logons with the new server?
Could someone be kind enough to lead me through a step by step guide on the best solution.
Thanks a lot

I am running an Execute SQL task that does a Begin Tran, then the next task in the sequence is a data task which imports a XML file into two tables. If i doo a Rollback Tran only one of the two tables is rolled back.
Is it possible to have both tables rolled back from one Begin tran command or do i need to split the datatasl into two and treat each import as a seperate issue ?
The connection is set to retainsameconnection

Hi,
I want to rollback my t-sql if it encounters an error. I wrote this code:
begin tran mytrans;
insert into table1 values (1, 'test');
insert into table1 values (1, 'jsaureouwrolsjflseorwurw'); -- it will encounter error here since max value to be inputted is 10
commit tran mytrans;
I forced my insert to have an error by putting a value that exceeds the data size. However, I didn't do any rollback. Anything i missed out?

Hi,
In my case I have to log the errors raised by any task in a package to either windows event log, text file or SQL server. Also I need to send an email notifications to a group of people telling them about the error.
Now can I use SSIS package logging for logging the errors into the required destinations. I mean right clicking on the package and selecting Logging, then adding the required log providers and enabling the events for logging into those. I think I have to upfront select the log providers to log the error, I will not have the liberty to log the error to the destination, the name of which is passed as a variable to the package. This is okay with me though.
Now what will a custom log provider help me to do in this case. Also can I somehow configure my package to call the send mail task everytime an error is raised.
Also, one more option can be developing a package that only does the error handling. It will take in the paramters or the error codes and descriptions, the destination to write to and a flag to send mail or not for that particular type of error.
What do you think? Kindly advise.
Thanks in advance for your help and time.
Regards,
$wapnil

When looking at SQL Server error logs, I noticed that the current error
log had grown to 1MB whereas most of the files are only a few KB.
QUESTION 1: Can I set the max size for an error log file? If so, how?
QUESTION 2: If not, is there a workaround?
Thanks

I did a full backup of a db from one server(Express2005) and trying to restore it to a different instance of SQL2005 on the same development machine. (Also had some fulltext columns if that means anything)
Many failures but finally got it to report all was successful except the icon in Object Explorer shows (Restoring...) with no indication of any real activity going on. It's a tiny database with hardly any data in it.
Just not sure what the heck is going on there. It also won't let me into the database until this the (Restoring...) goes away.
Any advice on how to get this thing finished out?

To All:
On my SQL 6.5 box, I have a corrupt Tran log. I do not use my Tran log but now I am getting an 1105 error, that the log is full. I run Dump tran with no log but it does not work. I cannot perform any other function without getting the 1105 error. Now I tried to reboot and now it is hanging during reboot. It is hanging while checking the partition where the tran log resides. I went in to VGA Mode. Any ideas would be appreciated.
Many thanks,
Kelly

Does this seem right? We have our transaction logs set to "Truncate Log on Checkpoint" and they still grow over 1GB. Is it possible that one transaction (to a checkpoint) generates this much logged information? Will transaction log backups every 5-10 minutes help me out better or is this just a poorly written application?
Thanks!

We are planning to provide a disaster recovery facility for a production system. Clustering has been ruled out for technical reasons so we are considering either transactional replication or Log shipping.
Microsoft suggested the log shipping option but it seems a bit messy to me and only provides a warm standby in that it only copies log backups to the secondary machine.
Any ideas why log shipping was suggested in preference to transactional replication? Anyone have any experience in this area?
TIA Colin.
