Tran Logs And Backups
Oct 19, 2000What 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
Restoring Tran Logs To Standby
Jan 22, 2001I 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

Big Tran Logs, "extra" Backup ?
Mar 28, 2002I 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.

Log Shipping Will Not Restore Tran Logs On Secondary Server
Nov 6, 2006We'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?
Remove Old Backup And Tran Logs Thru Maintenance Plan Cleanup Task
Mar 27, 2007Has 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 ?
Logistics Of Begin Tran And Rollback Tran
Dec 19, 2007I 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
thanks
Begin Tran, Commit Tran
Oct 8, 2007
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?

DB Engine :: Write Logs To Windows Event Logs?

SSIS Logs Vs Custom Logs Components
Feb 12, 2007Hi,
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.

Readonly Setting For Database
Jan 29, 2004we have a database that only serves Select requests (no OLTP) for our very high traffic websites.
what are the benefits of turning on read-only setting for the database if there are no transactions occuring in the database?
does sql server put locks on tables for SELECT statements?
is it the same as using HINT (NOLOCK) ?
thanks

Readonly Access On Tables
Mar 1, 2005Hi,

Database Is ReadOnly When I Attach It...
Oct 12, 2007Using SQL Express in this case, I have a database on one machine using one instance of SQLExpress that I detach. I then copy the database to a USB drive and take it to a different machine and attach it to a different SQL Express instance and it comes in as ReadOnly and I know of no way to change it.
One difference is that I have different users on the two systems, is that the cause? I wouldn't think that this would cause the database to show as ReadOnly, thoughI would just think that I may not be able to access it aside from using sa.
What is the likely cause of this?
Thanks

ScriptComponent With Multiple ReadOnly Variables
Dec 11, 2006I'm having trouble with a script component in which I'm trying to use two ReadOnlyVariables. If I use only one of the two variables, everything works without issue. If I use both of the variables (as part of a comma-delimited list) I get the following:
The variable cannot be found. This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.
I don't believe the variables themselves are the problem. Both are scoped to the package level and I can use either of them if I have it as the only variable. Seems bug-like, but thought I'd get some ideas before pursuing that route.
Replicated Readonly Db And Temporary Tables

View 6 Replies View RelatedRestore Readonly Filegroup Sqlserver 2000
Sep 26, 2007
Hi,
I have a database running on sqlserver 2000. This database (let's call it TestDatabase) has 2 filegroups called 'PRIMARY' and 'SECONDARY', and is bulk-logged. The 'SECONDARY' filegroup is set to readonly since no data gets changed there by the applications, it is read-only data. Sometimes this read-only data needs an update, so I need to update the data in the 'SECONDARY' filegroup by running some long data-operations. These data-operations are executed and checked on a another database (which is a backup of TestDatabase) called TestDatabaseDemo. When everything is correct in TestDatabaseDemo we can copy all objects from the 'SECONDARY'-filegroup of TestDatabaseDemo to the 'SECONDARY'-filegroup of TestDatabase using DTS. This takes a long time and I want to try if I could speed up things by using the following strategy:
Take a full backup of TestDatabase
Restore full backup as TestDatabaseDemo
Run long-running data-operations on TestDatabaseDemo
Take a backup of TestDatabaseDemo
Restore only the 'SECONDARY'-filegroup from TestDatabaseDemo to TestDatabase, and keeping the 'PRIMARY' filegroup from TestDatabase as it was at that moment.
Suppose we arrived at step 5, I am executing the following commands:
Code Snippet
--make full backup of TestDatabase
backup database TestDatabase to DISK='G: emp estdatabase.bak' with init
--make full backup of TestDatabaseDemo
backup database TestDatabaseDemo to DISK='G: emp estdatabasedemo.bak' with init
backup log TestDatabase to DISK='g: emp estdatabase.log'
--restore secondary filegroup from TestDatabasedemo-backup
restore database TestDatabase FILEGROUP='SECONDARY' FROM DISK='G: emp estdatabasedemo.bak'
with move 'TestDatabase_Data_Secondary' to 'G: empTestDatabase_Data_secondary.ndf', NORECOVERY
--restore primary filegroup from Testdatabase-backup
restore database TestDatabase FILEGROUP='PRIMARY' FROM DISK='G: emp estdatabase.bak'
with move 'TestDatabase_Data' to 'G: empTestDatabase_Data.mdf', NORECOVERY
--restore log and try to get db onlin
restore log TestDatabase FROM DISK='g: emp estdatabase.log' with recovery
I get the following error:
The log in this backup set terminates at LSN 6000000021500001, which is too early to apply to the database. A more recent log backup that includes LSN 6000000022400003 can be restored.
When trying to execute "RESTORE DATABASE TestDatabase WITH RECOVERY; " as last statement
I get error:
The database cannot be recovered because the files have been restored to inconsistent points in time.
How i can restore the read-only filegroup correctly?

View 6 Replies View RelatedCan IN Clause Accept A Parameter Value?
Jun 19, 2000I'm trying to write an SP which takes a string parameter like '1,3,6,9' and then uses it in an IN clause of a SELECT statement to return a recordset, along the lines of:
SELECT
custname
FROM
mytable
WHERE theid IN @myparameter
...any ideas how to get this kind of thing to work. In the example, theid is a numeric value. What it needs to do, I guess, is do a string replacement of the parameter value, but the SP naturally enough attempts to compare the numeric theid value with the string @myparameter value and fails. It works OK if there's only one value in the string, because the server auto-converts the paremeter into a numeric, but if there are 2 or more values in the string then the server obviously can't do the conversion. How can I make this work?

A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 3313, Level 21, State 2, Line 1
During redoing of a logged operation in database 'XXXX', an error occurred at log record ID (0:0:0). Typically, the specific failure is previously logged as an error in the Windows Event Log service. Restore the database from a full backup, or repair the database.
Msg 3414, Level 21, State 1, Line 1
An error occurred during recovery, preventing the database 'XXXX' (database ID 7) from restarting. Diagnose the recovery errors and fix them, or restore from a known good backup. If errors are not corrected or expected, contact Technical Support.
Investigation DONE:
- DBcc checkdb shown Clean
- database is online and able to access
-Detached database and attached with rebuild log, still could not bring database read_only

Getting Query Is Accept Null Values
Mar 18, 2008I am trying to have a query with the option for items to be null. (So users don't need to fill in the other fields if they choose not too) SELECT Tickets.TicketID, Tickets.UserID, Tickets.SystemID, Tickets.Title, Tickets.Description, Tickets.Software, Tickets.Date, Systems.OS, OS.OS AS OstitleFROM Tickets INNER JOIN Systems ON Tickets.SystemID = Systems.SystemID INNER JOIN OS ON Systems.OS = OS.osIDWHERE (Tickets.Title LIKE '%' + @title + '%') AND (Tickets.Software LIKE '%' + @software + '%') AND (Tickets.Description LIKE '%' + @descrip + '%') AND (Systems.OS = @osid) OR (@osid IS NULL)This works when i give the LIKE values % as a parameter. So they can choose to search by title + software but not description or description and nothing else etc etc etc. The problem is, the osid. If I give it a value it works but if i try to do null, *. or % it always displays every item in the databse ignoring any of the previous like statements. Anyone have an idea?

Mar 4, 2008Hello. I have set up an SQL Endpoint using NTLM authentication. When I try to retrieve the WSDL file I am prompted for credentials. I put in username/password (this user has Connect access to the Endpoint) but its not accepted. The dialog reappears. The SQL error log shows an HTTP authentication failed error. I've triple checked that the username/password is correct.
Now here's the strange part: the same endpoint (exact same code for setting up endpoint, permissions, user, etc.) works just fine on another box (username/password is accepted and WSDL is shown). This leads me to believe that the problem isn't with SQL or the endpoint, but someplace else. I really don't know how to debug this one.
