Master database Rebuild

hi Team,
if we Rebuild the MASTER database [model and msdb ] re-created or not?
if rebuild the Master database internally what will be happen.
Thanks,

Rebuilding master is actually re-builts all the system databases from the scratch just like a fresh installation.
After rebuilding you might need to restore/attach the user databases.
Internally it resets all the configurations and properties of a SQL Instance

Master Database Rebuild failed

Hi All,
We have master Database corruption and there is no backup of it, so I have to rebuild the master database..And when i gave the command to rebuild
1. No error was thrown in Command prompt
2. SQL server started to run again.
3. I am unable to login even though I gave my windows login in the /SQLSysAdminAccounts
When I see the log detail it shows failed

Hi Hemanth,
Based on your description, my understanding is that you encounter a failure when rebuilding master database.
According to the error message, it might be caused by several reasons. There are some proposals for you troubleshooting this issue as follows.
1. Make sure that your SQL Server installation package is not damaged.
2. Make sure that your account has admin permissions. And confirm that the account has SeDebugPrivilege security privilege, you can check it in Group Policy.
Start | Run | Type: gpedit.msc | OK | Navigate to Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Debug programs
For more details about the error, you can review this similar thread:

Is it possible to create a new table in the master database with SSMS ?

Hello ,
I have problems with this thread :
http://social.msdn.microsoft.com/Forums/en-US/sqlexpress/thread/5153c43b-7844-41c4-a414-d14730abe435/
If no user database has been created , in SSMS , we can see only the 5 system databases ( master, msdb , tempdb... ).
Logically , the user should connect automatically on the Master database ( if the user is the same as this used to install a new SQL Server instance, this user should be sysadmin that's to say he/she has all possible permissions and especially dbcreator ).
Is it true that it is impossible to create a new table on the master database ?
I have done many researches about this possibility , all I have found is the advice : don't touch to the master database. This database is used to store critical information about the instance and its user databases. Even in the last book of Kalen Delaney
about SQL Server 2012 Internals , I have found nothing clear about the creation of tables in this database ( and what about the other system databases ? I am excluding tempdb ).
If someone has an idea about this thread and my questions , I would be thankful for a reply on this thread or on the related thread in the SQL Server Express Forum ( with my poor written English , I am not sure to have poster in a correct and understandable
way ).
If you think that this thread is not in the good forum , a moderator of this forum can move this related thread ( I have not done the move as I am not sure which is the good forum Database Engine or Transact-SQL ... )
Thanks beforehand and have a nice day.
Mark Post as helpful if it provides any help.Otherwise,leave it as it is.

If you add the current user during the installation you can have it as system admin , or you can add him/her later on
in SQL Server. BTW regarding dbcreator I have wrote some blog , need to read... :-)

You can (if you have needed permissions) to create objects in master database, usually I create objects for instance maintenance (like rebuild indexes...)

Copy Master Database To Another Instance

At our instasllation we have copied the Master database across instances with success. This makes migrations much easier and it has never caused any issues. However I am concerned whether this is officially supported and if there may be something we are
not considering that may cause issues in the future. Of course the source and destination SQL Server instances are the same OS and SQL Server versions and the paths of all databases are the same.
Thank you for your help
Scott

Hi,
I think this method can be used when the backup restore method does not work because of the original database files were corrupted or missing.

How do you declare objects in the master database

I am trying to register our CLR assembly as an unsafe assembly without having to make the database trustworthy. Since making the database is_trustworthy_on = 1 is not a best practice, and would cause some of our customers (and our development process)
a little bit of grief.
I have read a ton about it but am still having trouble.
The reason the assembly is 'Unsafe' is because it is calling the TimeZoneInfo class to convert between timezones, since we are not yet on UTC dates. We plan to in the future but that's a big project.
We are also not using the 'SQLCLR' but rather have written our own class library and just have a project reference to it, which works just the same, but we have found to be better for the C# programmers.
I am playing with signing the assembly using an SNK file and have figured out what I need to do, including 1) creating a master key, 2) creating an asymmetric key using the same SNK file that signed the assembly, 3) creating a login for the asymmetric key,
and 4) granting unsafe assembly to the login.
When I do all that with straight SQL, it actually works! But I am having trouble fitting this into our SSDT world.
Should I create a separate SSDT project for items #1 through #4 above, and reference it, and check 'Include composite objects' in our publishing options? As stated in this blog post though, I'm terrified of messing up the master database, and I'm not
excited about the overhead of another project, a 2nd dacpac, etc.
http://blogs.msdn.com/b/ssdt/archive/2012/06/26/composite-projects-and-schema-compare.aspx
Since we do use a common set of deployment options in a deployment tool we wrote, which does set the 'block on data loss' to false, and the 'drop objects not in source' to true, b/c we drop tables all the time during the course of refactoring, etc.
I don't want to drop anything in master though, and I don't want to have to publish it separately if we didn't have to.
I suppose I could just have some dynamic SQL in a pre-deployment script that takes care of the master database, but I was trying to do it the 'right' way, in a declarative style, but struggling.
So, in short, what's the recommended approach for getting an 'unsafe' CLR assembly into an SSDT project?
The error that started all this was:
CREATE ASSEMBLY for assembly *** failed because assembly *** is not authorized for PERMISSION_SET = UNSAFE.
The assembly is authorized when either of the following is true:
the database owner (DBO) has UNSAFE ASSEMBLY permission and the database has the TRUSTWORTHY database property on;
or
the assembly is signed with a certificate or an asymmetric key that has a corresponding login with UNSAFE ASSEMBLY permission.
Also, would a certificate be better than an asymmetric key? I'm not entirely sure of the difference just yet to be honest.
Thanks,
Ryan

After much fighting with this, figured something out as a workaround, and thought I'd share it.
First, I'm pretty certain the SSDT declarative way for these master objects just doesn't work yet.
My workaround was to make a pre-deployment script (that runs when we create new databases, as well as for the current release), that takes care of the security items needed to support a signed CLR assembly with unsafe permissions.
One issue we were running into was when it came to creating the asymmetric key, there are 4 ways to do so, and we didn't want to depend on a hard-coded/absolute file path. The 4 ways are "From file", "from external file", "from
assembly", or "from provider". I still don't 100% understand the from provider way, but ultimately we are actually using the from assembly way, with a little trick/hack I did that allows us to not have to use the 'from file' way and to
reference a hard-coded path on someone's C:\ drive. I really really didn't want to do that b/c we create local dev databases all the time and not everyone has the same paths setup. Also, our databases are deployed on our servers as well as remote-hosted-customer
servers, and up until now, the database release has not needed file system access. Even the CLR itself is created using assembly_bits, which is awesome.
So I thought of something...
What if I had a simple/temporary assembly, which I create from assembly_bits, use to import the public key from, through the create asymmetric key from assembly command, and then drop as if it never existed?
Well...it works!
Here is my current prototype of a pre-deployment script, which I'll go through and cleanup more, but thought I'd share. I also want to document how I created the temporary assembly_bits in case anyone ever wants or needs to know, even though they really
shouldn't. But it should make them feel better. Basically I just created did this to get them:
1 - Created a C# Class Library project in the solution.
2 - Added our .SNK to that project and removed the 'Class1.cs' that it created by default
3 - Signed that class library with the .SNK
4 - Added a project reference to that class library from the main database solution.
5 - Generated a deployment script (but didn't run it) and grabbed the create assembly statement (copy/paste)
6 - Deleted the temporary project
7 - Pasted the code I had copy/pasted into the pre-deployment script
Note that the objects do apparently need to go into MASTER, so at the end of the pre deployment script, I switch back to the automatic [$(DatabaseName)] after first having done USE master.
Hope this helps someone. Finally got it!
BTW - The other way we almost used was to introduce a SqlCmdVariable of $StrongNameKeyFilePath but that would have been a hassle for people to set whenever they got a new machine, etc.
Thanks,
Ryan

Why can't I edit the Master Database

Can someone from NI please explain the reasoning behind not letting the user edit the master database? I want to do something simple like remove one of the redundant + and "dot" polarity indicators on some of the capacitor footprints without having to, one by one, change each capacitor to use my custom footprint.
I have found several errors in the master database yet I can't fix those parts or footprints or remove them, thus increasing the likely hood that they will get used by mistake/unknowingly again.
The only explanation that I can come up with is poor database design and fear of me "breaking" it. Something as simple as editing a part through the GUI should be simple enough to do to, please let me. No offense, but your master database is not good enough to warrant "no edits". Most parts I use are from the local database, but that is not an option for special case parts like resistors and capacitors.
Also, why I can't edit the database itself without using the GUI? (as is an option in all other CAD packages that I've used). The GUI entry point is extremely time consuming and error prone when a database script can often easily create error/typo free part numbers using existing symbols and footprints.
Greg

There are several ways you can achieve the results you looking for with respect to RLCs.
Ultiboard first searchs the User then Corporate the Master database when looking for footprints. So, if you want to make a modification to a footprint, make the copy the appropriate in Ultiboard into your User database. Then modify the footprint. When you transfer from Multisim to Ultiboard, Ultiboard will pick the footprint you customized (or fixed).
One thing to watch out for is determining the correct name in Ultiboard. The name in Multisim is often not the name in Ultiboard. I don't know of any simple way of determing the mapping.
Place the component with the footprint that you want to change (in Multisim)
Double click the component, and click Edit Footprint on the Value page
Click Select from Database. The footprint should be selected. The name in Ultiboard is the Ultiboard Footprint column (if it is blank, then the name in Multisim and Ultiboard is the same).
You can add new footprints to the list in the Place Component dialog. You do this in the Database Manager.
Go to Tools > Database > Database Manager
Select the RLC Components tab
Click the Add button to add a new definition. Note, the definition will appear for all components of the same type. Also watch out for the polarity of capacitors and other components where relevant.

Master Database cannot be accessed

So I have bought the newest version (12.0) of Multisim for Academic versio for almost a month. I have never been able to properly used this software. The first installation was working fine, but when I tried to build my circuit design, it turned out that many OpAmp components were missing (eg. TLC277). I spend a couple hours Googling to find whether there were anyway I could update my components database with no luck.
After a few reinstallations and update to 12.0.1, this software simply stoped working. The error message of missing Advance database pops up everytime I start the software. So I proceeded to search through a few forums and found out there were some registry posted as to solve the problem. I tried installing the register many times and I ended up with no luck. I tried to do registry clean up and reinstall the softare again and again. Nothing has worked so far. It's really frustrating. I'm hoping if there is any solution at all.
I am using windows 7 64-bit ultimate dual boot on mac bootcamp.
Solved!
Go to Solution.

I have the student edition. I guess that is one of the reason why I could not find that component in first place.
I might be wrong. I just don't why they limit such basic component for student. It is one of the reason I need to purchase the software in the first place.
I have friends who install previous version of the software with all the needed components.
Yet still, that does not solve the problem I am having. For, the software itself can't even access the master database
("Problem: Accessing the database.The Master Database cannot be accessed. Features using the Master Database will not be available.") ,meaning it is practically unusable.
Thank for your response.

Master database logical file names are different - Please Help!

Today I noticed that one of the server in our environment,
when i run
SELECT *
FROM sys.database_files
i got results
data_space_id name
1 master2
0 master_Log2
Please note logical name of the master database files.
But, in SSMS if i right click and choose properties for master database, it shows logical file names are master, mastlog.
How can this be happened? How can i fix this issue and make it both same names for master database?
Please help!

CREATE ROLE doesn't work in master database

Running the CREATE ROLE statement in master database as server-level principal gives:
Msg 15247, Level 16, State 1, Server NNN, Line 10
User does not have permission to perform this action.
Running the same statement in user database succeeds. Is there a way to create a role in master database in SQL Database?

Hi Martin,
Thanks for reaching out. It is not possible to create roles in the logical master in SQL database. Some more information on user management in SQL database can be found here: https://msdn.microsoft.com/en-us/library/azure/ee336235.aspx

Adding a stored procedure to the master database?

I have a SQL server instance being used as our data warehousing environment. The instance consists of several databases that I am snapshotting as part of our high availability strategy for data. I've created a stored procedure that takes the source database
as an argument and that will create a new snapshot when a new one needs to be created and will also automatically remove the old snapshot. It also updates some synonym tables that point to the new snapshot but that might not be an important detail.
I would like to have the stored procedure stored some place global to all of the databases that I am routinely snapshotting, but that would mean putting it in the master database. Although having it there makes things significantly better in terms of usability,
it seems like there's something wrong with putting any stored procedures in the master database. Am I wrong? Is it OK to put stored procedures there in situations like this?

Yes Database snapshot. We're using it to make our data more available so that when we're refreshing the underlying database we can still access the previous version of the data. Otherwise our reports and applications won't have access to the data or will
get partial data sets. We don't intend to use it for DR or as a backup.
ok. if it is for temporary purpose, it will work..
you can create one master procedure and do that - master database. but you need to make sure you point your applications/reports to the snapshot database and not actual database
Hope it Helps!!

Migrating master database to another server (DR testing).

So I was tasked to do some DR testing, by moving one of our environments to another. I was tasked with moving 1 user database called Vant, master, and msdb. I managed to accomplish it, but it wasn't easy and a little messy. I'm looking
to see if you guys can help me clean my steps up a bit.
Environment backgroud.
Both environments are SQL Server 2012 Enterprise
Build: 11.0.3368
Instance Name: Default
Process
I took all 3 backups from my source server and placed it in a network location where my destination server can access.
1) I began by trying to restore master database by placing my instance in single user mode, backup restored.
2) when I removed the destination instance from single user mode, the service would not start, did this a couple of times, but no luck.
3)I also made sure the startup parameters were pointing to the right folder location
4)Then I thought, maybe it was the folder location where it restored to, that was causing the problem because they were different; so I went ahead moved master into a folder location that would match the source, i also changed the startup parameters, but
the instance still wouldn't start
5)So then I checked the event logs, and noticed that SQL Server was looking for databases that were on the Source Instance, as well as some of the system databases that I hadn't moved the files to the new folder location
6)Restored the original master database from the destination server so that I could get the service going
7) moved all the system databases from the old folder location on the destination server to where master now resided; created two empty databases with the names the event log was looking for.
8)Restored master database from source server, and the service finally started up
9)When I went into SSMS, I noticed that the two empty databases I created were in recovery pending
10) dropped one of the databases I didn't need, and restored the Vant database, as well as msdb; everything looks good.
So there it is, I totally don't feel good about this. I don't like the fact that the databases came up in "recovery pending" and also that I had to create the databases it was looking for before I could restore and start up the service, but
maybe that's just how it is. Any advice you can give me on how to clean this up would be much appreciated.

Hi,
Did you reffered to Microsoft doumentation on how to move system databses.
http://technet.microsoft.com/en-us/library/ms345408(v=sql.110).aspx
For user databse backup when you restore on different server you use with move option to physically give location to mdf and ldf files.
Moving system database is little tricky

Alert error when master database is down

When the master database is down (server maintenance, offline back up) a lot of error messages appear in the alert.log of the slave database. Is possible to disable registration of error ORA 12012 and related when master database is closed ??

No, errors reported by the SNP processes, like most background processes, are always recorded in the alert.log
