As you now BizTalk terminator is asking you 3 questions when the tool starts

1. 1.All BizTalk databases are backed up?
2. 2.All Host Instances is stopped?
3. 3.All BizTalk SQL Agents is stopped?

This is ok when you are going to actually change something inside BizTalk databases but this is not what you are going to do in this scenario you are only using the tool to read from BizTalk databases. But you should always have backups off BizTalk databases.

You are always responsible for what you are doing, but when we have used this tools in the way I describe we have not have any problem with this scenario.

So after you have start Terminator tool please click yes to the 3 questions(you dont need to stop anything in this scenario) then connect to the correct environment please do this in your test environment first so you feel comfortable with this scenario, the next step is to choose a terminator task choose Count Instances(and save messages) after this you have to fill in the parameter TAB with correct serviceClass and Hostname and set SaveMessages to True and last set FilesaveFullPath to the correct folder you want to save the messages to.

Then you can choose to click on the Execute Button and depending of the size and how many it can take some time, after this disconnect Terminator do NOT do anything else.

You should now if you have filled in the correct values in the parameter TAB have the saved messages inside the FilesaveFullPath folder.
