Did you attend any Microsoft class and need the lab files?

Leave a comment

Well, they are a bit difficult to get from the virtual machines, and almost impossible if you have been using LabsOnline.

Microsoft has compiled a page with a lot of lab files and setup scripts here:

https://www.microsoft.com/learning/en-us/companion-moc.aspx

I guess they are pretty useless without the lab instructions, but feel free to download them 🙂

And speaking of download… The SQL Server sample database location is still codeplex…

Happy sampling

In about two weeks I’ll be one of the “Titans” on stage at Informators event Clash of the Titans. If you want to see us (me and Mattias) in a “what feature is most useful” battle with the new SQL Server 2014 as starting point.
The date is April 28. The information is here http://informator.se/seminarier/event/clash-of-the-titans-sql-server-2014 and you are invited!

Speakers dinner on the way

Leave a comment

I was selected as a speaker at the SQL Saturday #275 in Copenhagen, Denmark. Now I’m at the hotel, polishing the presentation while waiting for the speakers dinner.

<yoda>A nice tradition, the speakers dinners are. </yoda>

Hopefully a lot of people will join tomorrow for a day full of SQL Server stuff.

Links and downloads will show up after the conference…

Restore Master

1 Comment

You’ve just rebuilt your master database. You discover that your other databases are gone, all logins are missing, pulse is rising…

If you take regular backups of your system databases (master and msdb primarily) you have nothing to worry about. If your database files are on undamaged drives you are even better up.

To get all the logins back and all of your user databases “re-attached” you only need to restore your master database. And restoring the msdb database gets you the jobs, schedules and alerts back as well.

To tell the truth: This is not something you do every day, it may even be a bit scary. So here is a simple way to restore your master database, that works in SQL Server 2008, 2008 R2, 2012 and in 2014.

NOTE: commands are written against the default instance (named MSSQLSERVER). If you have a named instance, you’ll have to find the name of it first…

1. Start an elevated command prompt.

2. Run : net stop mssqlserver

3. Navigate to your instance’s “binn” folder (i.e. “C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn”)

4. Run : sqlservr.exe -m -c -s MSSQLSERVER
This starts sqlservr (the server executable) in single user mode (-m) as a console/not service application (-c). And the instance name is MSSQLSERVER (the default instance)

!I got a warning from Windows built in firewall at this step. It’s perfectly OK to ignore, and NOT let the application communicate on networks – we’re local so the restore will work anyway.

5. Start ANOTHER Command prompt – DO NOT close the other one.

6. Run : sqlcmd -s. –E
SQL Server command tool logs in to the default instance, locally (-s.) with Windows Authentication (-E)

7. 1>restore database master from disk = ‘full path to backup file ‘
2>GO

Your other window should now be back at the command prompt. Database restored.

Since the method uses only console tools, it works fine on servers with sparse UI possibilities Ler

Rebuild Master

2 Comments

The master.mdf is corrupt. The disk failed… Powerfailure? This never occurs at a convenient time. The ERRORLOG-file has a message similar to this.

Error 2(failed to retrieve text for this error. Reason: 15100) occurred while opening file
‘C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\master.mdf’
to obtain configuration information at startup.

This is of course easily fixed. It’s only to resore the backup we have of all our system databases. Just one small problem… SQL Server doesn’t start.

Time to rebuild the system databases. But first : Documentation!

  1. Look for “Authentication mode is MIXED.” (or “Authentication mode is WINDOWS-ONLY.” ) Write it up.
  2. Document what Collation you want. If you want “same as before”, just forget it. Otherwise write the new Collation on the same piece of paper. (I’m documenting “Finnish_Swedish_CI_AS”)
  3. How do you connect to SQL Server? If you have a backslash somewhere in your servername, you have a named instance. (connecting to COMPUTER\FINANCE gives you the instancename FINANCE) However if you only use the servername, you probanly have a default instance, in which case the instancename is MSSQLSERVER – Onto the paper!

 

Command:

Same syntax since SQL Server 2008. Still works in SQL Server 2014 (CTP2) and has no signs that it would stop working:

Setup.exe /ACTION=REBUILDDATABASE
/INSTANCENAME=MSSQLSERVER  
/SQLSYSADMINACCOUNTS=win7x64pro\mikael 
/SAPWD=P@ssw0rd
/SQLCOLLATION=Finnish_Swedish_CI_AS

  • ACTION – obviously
  • INSTANCENAME – the instancename documented in item 3.
  • SQLSYSADMINACCOUNTS – Windows account(s) who will be sysadmin of the server.
  • SAPWD – This parameter MUST be present if item 1 states the server started with MIXED autentication.
  • SQLCOLLATION – from item 2.
  • QUIET – I recommend using this. Saves some clicking.

OK, now you’ll have to run this command in an elevated command prompt. That is the command prompt starting in C:\Windows\System32 instead of in your user profile. Then it’s only to navigate to the folder of “setup.exe” and run the command line. All words are typed on one line BEFORE hitting ENTER!

If your installation is made with C:\Program Files\ as the root, the setup.exe can be found here:

SQL 2008 – C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Release\Setup.exe

SQL 2008 R2 – C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\SQLServer2008R2\Setup.exe
(I found another setup.exe in the same folder as for SQL 2008, but running that file generated errors instead of databases…)

SQL 2012 – C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012\Setup.exe

SQL 2014 CTP2 – C:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\SQL14CTP2\Setup.exe

and my guess is that RTM of SQL 2014 will use the same path as before:
C:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\SQLServer2014\Setup.exe 
or potentially 
C:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\SQL14\Setup.exe

I was again among the lucky few who was selected as speaker at the Nordic Rally. The Rally takes place near Arlanda airfield, Stockholm the 5-6 November. My talk is about the transaction log. Please come and check it out… There are of course more than 20 other interesting subjects and speakers making this a worthwhile investment.
