Changing the tempdb Collation

The collation of tempdb cannot be changed by using the ALTER DATABASE statement—
SQL Server does not allow this since tempdb is part of the system database. Note that
tempdb uses the collation of the model database. Since there is a way to change the
collation of the model database, we inferred that we should be able to change the
collation of tempdb. Recall that the model database can be backed up and restored. So,
for example, if we have another instance of SQL Server running with a default collation
of French_CI_AS, we can back up the model database from the “French” server, restore
it on the target server, and then restart the MSSQL service on the target server. We
used this technique to change the collation of tempdb for the test cases described in
the previous section.
Note that SQL Server uses the model database as a template to create new databases.
Continuing our example, new databases would have the default collation set to
French_CI_AS.

Introducing SQL Server 2008 R2

■ The Utility Control Point (UCP)
As the central reasoning point for the SQL Server
Utility, the Utility Control Point collects configuration and performance information
from managed instances of SQL Server every 15 minutes.

■ Data-tier applications
A data-tier application (DAC) is a single unit of deployment
containing all of the database’s schema, dependant objects, and deployment requirements
used by an application.

■ Customization of utilization thresholds and policies DBAs can customize the
utilization threshold and policies for managed instances of SQL Server and deployed
data-tier applications to suit the needs of their environments.


■ Parallel Data Warehouse Parallel Data Warehouse is a highly scalable appliance
for enterprise data warehousing. It consists of both software and hardware designed to meet the needs of the largest data warehouses.

■ Installation of SQL Server with Sysprep Organizations have been using the
System Preparation tool (Sysprep) for many years now to automate the deployment
of operating systems. SQL Server 2008 R2 introduces this technology to SQL Server.
