The 16th cumulative update release for SQL Server 2012 Service Pack 1 is now available for download at the Microsoft Support site. Cumulative Update 16 contains all the hotfixes released since the initial release of SQL Server 2012 SP1.

Those who are facing severe issues with their environment, they can plan to test CU16 in test environment & then move to Production after satisfactory results.

Although, I prefer to have SP2 with latest CU in your environment.

NOTE: This is the final Cumulative Update for SQL Server 2012 Service Pack 1. SQL Server 2012 SP1 exits service pack support on July 14, 2015.

Steps of Moving MSDB & Model SQL Server system Database to new locaation:-

1) Check current location of MSDB & Model Databases by executing below query

SELECT name, physical_name AS CurrentLocation, state_desc

FROM sys.master_files

WHERE database_id in (DB_ID(‘MODEL’),DB_ID(‘MSDB’));

You can also use “Execc SP_HelpDB ‘<DBNAME>’” for these details.

2) Execute Alter Database command with mofigy file option to set file loccation for dataabase

USE MASTER;

GO

ALTER DATABASE MSDB MODIFY FILE (NAME = MSDBDATA,

FILENAME=’E:\SQL2K5_1\Model\MSDBDATA.mdf’);

GO

ALTER DATABASE MSDB MODIFY FILE (NAME = MSDBLOG,

FILENAME=’E:\SQL2K5_1\Model\MSDBLOG.ldf’);

GO

USE MASTER;

GO

ALTER DATABASE MODEL MODIFY FILE (NAME = MODELDEV,

FILENAME=’E:\SQL2K5_1\Model\MODEL.mdf’);

GO

ALTER DATABASE MODEL MODIFY FILE (NAME = MODELLOG,

FILENAME=’E:\SQL2K5_1\Model\MODELLOG.ldf’);

GO

OUTPUT :-

The file “MSDBDATA” has been modified in the system catalog. The new path will be used the next time the database is started.

The file “MSDBLOG” has been modified in the system catalog. The new path will be used the next time the database is started.

The file “MODELDEV” has been modified in the system catalog. The new path will be used the next time the database is started.

The file “MODELLOG” has been modified in the system catalog. The new path will be used the next time the database is started.

3) Stop SQL Services

4) Manually Move MSDB & Model Databases files to new location

5) Start SQL Services

6) Check MSDB & Model Databases file location after movement

Question : Database snapshot captures only data changes or it will also save real database from DDL changes (like table structure, store procedure etc.)

Answer : Yes.

So here we explian how :-

Databse snapshot is read only databse. It’s a static view database on which only read only operaton can be performed. Database snapshot works on data page level. Before a page of the source database is modified for the first time, the original page is copied from the source database to the snapshot. The snapshot stores the original page, preserving the data records as they existed when the snapshot was created. The same process is repeated for every page that is being modified for the first time.

So DB snapshot works page level & page is the smallest unit database engine can understand. Page contains the actual data, transactions and schema details. So here, I say snapshot works on page (not only data pages) and any change in page will move page to DB snapshot.

Break up of complete storage cycle :- Windows Server > SQL Instance > Database > Database Files > Extends > Pages
