tracker issue : CF-3041799

Duplicate ID:	CF-3041827

Problem:

Tried to update CF9 Standard (Windows 2003, IIS) to 9.0.1.After completing the update process, all I get is a CF error "The DataSource service is not available". I tried restarting both the services and the server, but with no luck.On investigation, I found the Adobe help note which explained how to downgrade and remove the update. So I followed the instructions - replacing all the backed up files, clearing the clas cache, restarting the server - and now I get the message "The tag handler query does not have a setter for the attribute ormOptions specified in the Tag Library Descriptor".So my only course of action (bear in mind this is a live server - my test server updated without a hitch) is to uninstall CF9 and reinstall it. Unfortunately, this also removed all my settings (even though the uninstaller seemd to imply that they would be retained) and I had to spend the next hour recreating data sources, extensions and server settings.What is the problem with the update? I've now seen a number of other people with the same problem; and much as I want to install the update, I'm going to hold off until there is some sort of clarification on what's going wrong.Nogt sure if it's relevant, but I also have Fusion Reactor installed on the server (but not with the datasource wrapper).
Method:

1. Install CF 9.0.1 update.2. Restart and go into blind panic when the web server doesn't work.
Result:

The DataSource service is not available
