Introduction

Windows PowerShell is a Windows command-line shell designed especially for system administrators. It includes an interactive prompt and a scripting environment that can be used independently or in combination. PowerShell can be used by BizTalk administrators to help them in automating tasks. This can be done by creating scripts or commandlets or using for instance the PowerShell Provider BizTalk. In this article you find all necessary tools and resources to become proficient in using PowerShell in your BizTalk environment.

CodePlex

On CodePlex you can find the PowerShell Provider BizTalk. It is a project that  allows you to administrate your BizTalk Server.

The project is divided into two components :

• The BizTalkFactory Management Automation Layer
• The BizTalkFactory PowerShell Provider

The BizTalkFactory PowerShell Provider is a PowerShell Snap-In for BizTalk Server 2006 R2, BizTalk Server 2009 and BizTalk Server 2010 that allows developers and administrators to easily automate routine and complex BizTalk administration tasks such as deploying applications, and managing configuration and run-time data using Windows PowerShell. Administrators can further increase productivity by leveraging the many cmdlets included with BizTalkFactory PowerShell Provider.

The PowerShell Provider BizTalk is not the only initiative on CodePlex. Another one is the PowerShell Tools for IT Admins. It is a PowerShell Module that allows you to control Microsoft BizTalk Server (2006+) via PowerShell.

Using PowerShell Scripts to restore BizTalk Databases

Configuring the backup job for BizTalk is a fairly simple task, while restoring it is a bit more complicated. By default the BizTalk backup job makes a full backup once a day, and a log backup every 15 minutes. When backups are done, a mark is set on each file. This mark is the same across all databases, and should be used to restore all databases to the same point in time and keeping all databases in a consistent state.

The only supported disaster recovery procedure from Microsoft is log-shipping. Although log-shipping comes with many advantages, it is still expensive since it requires a secondary SQL cluster.BizTalk doesn’t come with any restore scripts/features other than log-shipping. Hence Mikael Håkansson a BizTalk Server MVP has come up with the PowerShell scripts, that will allow DBA's to restore the backup and log files created by the BizTalk jobs into a secondary SQL server, without the need for maintaining an expensive stand alone SQL cluster.

The scripts can be downloaded from here http://blogical.se/blogs/mikael/archive/2011/02/22/powershell-cmdlet-for-biztalk-db-restore.aspx.

The sample comes with two cmdlet’s:
Get-Marks and New-RestoreDatabaseFromMark. The first one gives you a list of all marks from all log files. The second one, as the name implies, restores a database to a specific mark. When doing so, the database will be restored from the last full backup before the mark. After that, all log files will be restored in order from the full backup. The last log file will only be restored to the specified mark.

You can use the New-RestoreDatabaseFromMark cmdlet with or without specifying the mark. Leaving the mark empty is equivalent to last mark.
