BizTalk : How To : Save suspended messages in BizTalk Vb Script

Last week, I needed to save 700+ suspended messages to file. I didn’t want to go in to each instance and click ‘save to file’ 700 times. A quick search in the web did not find what I want, however there were a number of articles about extracting messages from the BizTalk tracking database. One of which is this excellent article by Thiago Almeida.

My scenario was for an existing BizTalk 2004 implementation in the company and is only a once-off thing I need to do. For the newer BizTalk 2006 applications, there is the ‘Failed Message Routing’ feature that can be enabled on send ports and receive ports. The failed messages could then be easily subscribed to a send port to output to file.

Then it occured to me that the WMI script Terminate.vbs has the option to save the messages before terminating the instances (http://go.microsoft.com/fwlink/?LinkID=107591 and slightly updated for 2009). Thus changing this script to do what I want required the least effort. I could just use the script as it is to save all the messages and terminate the instances. However it didn’t take much to modify it to take a parameter for filtering on an instance name and to only save messages (and not terminate them). Below is the usage description of the save_messages.vbs script and the actual script. It works for BizTalk 2004, 2006 and 2009.

There is also a replacement of the Terminate.vbs script: Biztalk Terminator.

Usage:
cscript save_messages.vbs < -Z | -A | -DIS | -SR | -SNR > [Port/Orchestration name]

-Z saves all “Zombie” instances (e.g. completed with discarded messages)
-A saves all suspended and zombie instances as well as all routing failure reports
-SR saves suspended resumable instances only
-SNR saves suspended non-resumable instances only
-DIS saves all dehydrated ‘isolated adapter’ instances
optionally supply the name of the orchestration or port name to filter on specific instances

Ensure that the C:\Temp folder exists before running as that is where it saves the instances

Example: cscript save_messages.vbs -z “E-Reporting Data Transform Port”

Visual Basic Script:

‘ save_messages.vbs
‘ Enter save_messages.vbs with no arguments from a command prompt for usage
‘ This script needs to be run under a user account that is a member of the BizTalk Administrators
‘ group. This script needs to be run on a machine that is configured with BizTalk administration
‘ tools.
