SQL DB - restoration failing

June 17, 2015, 11:59 pm

Hi,

I have taken Backup of a database into multiple files.And i moved them to new location and tried to restore to a new DB server.

But the restoration is failing with below error.

The backup data at the end of "test1.bak" is incorrectly formatted. Backup sets on the media might be damaged and unusable. To determine the backup sets on the media, use RESTORE HEADERONLY. To determine the usability of the backup sets, run RESTORE VERIFYONLY. If all of the backup sets are incomplete, reformat the media using BACKUP WITH FORMAT, which destroys all the backup sets.  Error: 3266, Severity: 16, State: 1.

I think its not problem with versions. Can you please help me to understand the nature of the error ?

And please help me to solve this error.

Thanks,

Vinodh Selvaraj

Restore a backup file to a remote server using TSQL

I am working on a project for an SQL job. I am:

1.) Taking a database out of an availability group,

2.) Setting the recovery to simple,

3.) Shrinking the log file,

4.) Setting the recovery mode back to full,

5.) Then backing it up.

I need to restore the file to my secondary server with replace and non recovery mode. I am having trouble performing that call?  I have the code to reestablish the database to the availability group if I can get the restore feature working.

Hi ,

Have 6 SQL Server 2012  failover clusters  environments on Windows 2012 R2 standard edition.

Have intermittent connectivity issues  when using Windows Authentication, with the error "test connection failed because of an error in initializing provider. login timeout expired" . Am checking by using a UDL file and have tried the below.

1) Have made port changes to use static 1433 port.

2) Have enabled shared memory and using Named Pipes and TCP/IP by using cliconfig.

3) Have turned off firewall.

4) Loopback is disabled

5) SQL Browser is running, have changed 'Built in Account setting'  from 'Local Service' to 'Network Service'. but with no effect.

I have tried other suggestion from forums and websites but still  I am getting intermittent connectivity issues. Please help ASAP as this issue has become a big escalation now.

Thanks and Regards,

.NET Application experiencing significant slowdowns/wait times since upgrading from 2008 to 2014

July 9, 2015, 2:34 pm

We recently upgraded the SQL Server database used by our .NET application from version 9.0.4035 to 12.0.2000 (2014).

We were occasionally experiencing slowdowns on the old server while using the .NET application concurrently with heavy use of MS Access queries, so we were anxiously looking forward to the upgrade expecting a significant improvement in performance and throughput.

Unfortunately, quite the opposite has occurred.  Since the upgrade users are experience long wait times just within the .NET application, which is compounded when Access queries are being executed simultaneously.

My .NET developer has done quite a bit of research on this, and so far has:

1.  Set the database Compatibility level to SQL Server 2008

2.  Set the Auto Close option on the database to False

3. Updated the code to include "SET TRANSACTION LEVEL READ UNCOMMITTED" per the following article:  

(Article is in social.msdn.microsoft.com forum under sql-server-2014-reseting-isolation-level forum = sqldatabaseengine.  This won't let me post the exact link.)


So far none of these changes have made a difference.  The users are getting very frustrated with the wait times, and now they are actually "scheduling" times when they can have sole access to complete their updates.

Can anyone shed any light on what we may have configured incorrectly on the database, or what code changes are necessary in the 2014 version?

Thanks so much for your help!

Hi

We have a linked server that has been functioning without issue for a couple of years. Yesterday we changed the password of the user the linked server uses to login to the remote server/db and now the linked server throws an error 7303 when we try and change the password in the linked server security tab. Still using the same UserID just changed the password.

I can login to the application with the UserID and new password without a problem but when trying to apply the new password to the linked server get this error...

Hello,

I would like to use PBM in my environment.

I was wandering if it's possible to create a policy that has several conditions from DIFFERENT facets.

The reason for it is because I would like to maintain only several policies.

I didn't see a way for it via the GUI. Is it possible ? 

Thanks,

Restore Database Master Key to another server without Service Master Key?

July 10, 2015, 1:25 pm
$

Greetings. So I have a DB in production that contains an encrypted column. I want to pick up that DB and copy it to an existing DEV server. Of course I don't have the existing password for the Database Master Key. Of course simply attempting to query the data results in this:

OPEN SYMMETRIC KEY myKey
DECRYPTION BY CERTIFICATE myCert
		select a.IDENTITYID, a.username, a.Password,  CONVERT(nvarchar(128), DecryptByKey(a.Password2)) AS [Password2],a.UpdateDate
		from account a

Msg 15581, Level 16, State 3, Line 1

Please create a master key in the database or open the master key in the session before performing this operation.

Note that I need to specify "decryption by certificate", as opposed to a password like other examples I've seen.

Anyways,  I need to get this going, but here's the catch: I don't want to backup the Service Master Key on my Prod box and restore to this DEV box. My concern here is what restoring the SMK to this DEV box may do to existing encryption, Linked Servers, etc. 

In this scenario, what can I do? I think I need to regenerate the Master Key on Prod with a password that I do know as referenced here, but want to make sure of this before I pull the trigger. Also, the REGENERATE command doesn't have a "decrypt by certificate" option, only by password. How does this apply for in my circumstances?

Thanks!

Thanks in advance! ChrisRDBA

Hopefully this is a simple question to answer.

I'm running the below query: 

SELECT sqltext.TEXT,
req.session_id,
req.status,
req.command,
req.cpu_time,
req.total_elapsed_time
FROM sys.dm_exec_requests req
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext
order by cpu_time desc

What measurement of time does the 'total_elapsed_time' column give? milliseconds, microseconds, etc...

Forcing an INSERT/SELECT to use a Parallel Plan

July 13, 2015, 7:44 am
$

I’ve been looking at a bug in an application stored proc. This merely inserts 7 million rows from one table into another (empty) table.

INSERT dbo.TradeDataPrimary (Id, SinaiTrade) 

SELECT ts.Id, CAST(ts.XmlTradeASvarbinary(MAX))

FROM dbo.TradePrimary ts

Both tables have a clustered index with the same key order (on the first column) but the query optimizer insisted on placing a SORT step in the query plan. This use a lot of tempdb which I wanted to avoid.

I discovered that the bug was a data type mismatch. Fixing the bug and/or dropping the clustered index from the target table before the insert resulted in the plan I expected, that is, with no sort.

I was hoping it would run faster but, unfortunately, as can be seen from the new plan below, a serial plan is used. This results in the insert taking nearly three times as long as the original.

I’ve been looking at Paul White’s article:

 http://sqlblog.com/blogs/paul_white/archive/2011/12/23/forcing-a-parallel-query-execution-plan.aspx

and Adam Machanic’s:

http://sqlblog.com/blogs/adam_machanic/archive/2013/07/11/next-level-parallel-plan-porcing.aspx

Both are excellent articles but neither approaches i.e. trace flag 8649 or make_parallel () give me a parallel plan.

Am I missing a trick here? Anyone any ideas on how I can force parallelism please? I know there are no features that require a serial zone in the plan otherwise the plan with the sort would not be parallel..

This is SQL Server 2012 Enterprise 11.0.5522.0, 512 GB of RAM and 16 procs.

Regards

Ken

Hi guys, 

I'm looking for a way to restore a database once a week automatically(i.e every Monday). I take the backup in one server and need to restore it in a second one. The backup comprises of four files (.mdf, .ldf, .ndf and .fs). The script would read the directory and choose the latest backup to restore it but I haven't found the right script to restore the database with all the files included in the .bak whether using powershell or T-SQL.

Any help will be be greatly appreciated.
