Part 1 of “Microsoft Windows PowerShell
and SQL Server 2008 AMO” illustrated how to install Windows PowerShell and
connect to an Analysis Service Servername. Part 2 illustrated how to use Windows
PowerShell and AMO to get the various Server properties of SQL Server Analysis
Service. Part 3 discussed how to use Windows
PowerShell and AMO to get database properties of SQL Server Analysis Service
and Part 4 illustrated how to create an Analysis
Service Database using Windows PowerShell and AMO. Part 5 illustrated how to backup an Analysis Service
database using Windows PowerShell and SQL Server 2008 AMO. Part
6 of this article series illustrated how to restore an
Analysis Service database from a backup file with no password protection. Part 7
of this article series is going to illustrate how to restore an Analysis Service
Database from a database backup file with password protection. It will also
illustrate how to change the default Database storage location to a new
Database Storage location when restoring.
In part 5
of this article, we took a backup of “Adventure Works DW 2008” database to a file named “Advent2008_1.abf” with no
password protection. We also took a backup of “Adventure Works DW 2008” database to a file named “Advent2008_2.abf” with password
protection. Thirdly, took a backup of “Adventure Works DW 2008” database to a file called “Advent2008_3.abf” with
password protection and no compression. In Part 6 we restored the Analysis
service database backup file “Advent2008_1.abf” with no password protection.
Now let’s
try to restore the database “Adventure Works DW 2008” from the file “Advent2008_2.abf”.
Connect
to Analysis Server using Windows PowerShell, using SQL Server AMO as shown
below. [Refer Figure 1.1]
[System.Reflection.Assembly]::LoadWithPartialName
("Microsoft.AnalysisServices") >$NULL
$server = New-Object Microsoft.AnalysisServices.Server
$server.connect("PowerServer3\SQL2008")
Note:
PowerServer3 is the hostname and SQL2008 is the Analysis Service instance name.
We now know the different options available in the restore method. You can
see the value information from the restore method. [Refer Figure 1.2]
$server.restore
From the
above cmdlet’s output, we see the following options are available for restoring
the Analysis Service database. Each option has different uses.
The above
cmdlet basically used the method shown below.
System.Void Restore(RestoreInfo restoreInfo)
All the
available restore methods are listed below.
System.Void Restore(String file),
System.Void Restore(String file, String databaseName),
System.Void Restore(String file, String databaseName, Boolean allowOverwrite),
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations),
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations,
RestoreSecurity security),
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations,
RestoreSecurity security, String password),
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations,
RestoreSecurity security, String password, String dbStorageLocation),
System.Void Restore(RestoreInfo restoreInfo)
We need one more library for restoring the database since we protected the database backup with a password. So let’s execute the following cmdlets as shown below. [Refer Figure 1.3]
Figure 1.3
$security= New-Object Microsoft.AnalysisServices.RestoreSecurity
$security.value__ = 1
Now let’s restore the database “c:\backup\Advent2008_2.abf” using one of the above listed restore methods. [Refer Figure 1.4]
$server.restore("c:\backup\Advent2008_2.abf","Adventure Works 2008 DW", $true,$NULL,$Security,"ABC123")
Figure 1.4
The above
command restored the “Adventure Works 2008 DW” database from the “C:\Backup\Advent2008_2.abf”
file. In the above example, we used the following method to restore it.
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations,
RestoreSecurity security, String password),
We could
restore the same database file with a different database name--say “Adventure
Works 2008 -2” using the same method. [Refer Figure
1.5]
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices") >$NULL
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices.Security") >$NULL
$server = New-Object Microsoft.AnalysisServices.Server
$location= New-Object Microsoft.AnalysisServices.RestoreLocation
$security= New-Object Microsoft.AnalysisServices.RestoreSecurity
$server.connect("PowerServer3\SQL2008")
$security.value__ = 1
$server.restore("c:\backup\Advent2008_2.abf","Adventure Works 2008 -2 ", $true,$NULL,$Security,"ABC123")
Figure 1.5
Launch
SQL Server Management Studio to see that the database has been restored with
the new name. [Refer Figure 1.6]
Figure 1.6
If we want
to restore the database backup file “Advent2008_2.abf” and move the database
storage location to a different folder rather than the default folder when
restoring, then we can use the method shown below.
System.Void Restore(String file, String databaseName, Boolean allowOverwrite, RestoreLocation[] locations,
RestoreSecurity security, String password, String dbStorageLocation),
Let’s
restore the database backup file “Advent2008_2.abf” as “Adventure Works 2008 -3” using the above method. Here we are going to change the
Database location to E:\Data. [Refer Figure 1.7]
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices") >$NULL
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices.Security") >$NULL
$server = New-Object Microsoft.AnalysisServices.Server
$location= New-Object Microsoft.AnalysisServices.RestoreLocation
$security= New-Object Microsoft.AnalysisServices.RestoreSecurity
$server.connect("PowerServer3\SQL2008")
$security.value__ = 1
$server.restore("c:\backup\Advent2008_2.abf","Adventure Works 2008 -3", $true,$NULL,$Security,"ABC123","E:\Data\")
Figure 1.7
After restoring,
you see the database “Adventure Works 2008 -3” appear in SQL Server Management Studio. [Refer Figure
1.8.]
Notice
that the Data files are restored to a new Database Storage location E:\data\Adventure
Works 2008 -3.3.db folder. [Refer Figure 1.8 and 1.9]
Figure 1.8
Figure 1.9
Conclusion
Part 7 of
this article series has illustrated how to restore an Analysis Service Database
from a database backup file with password protection. It also illustrated how
to change the default database storage location to a new database storage location
when restoring.
