Unknown comparitor key ‘protocol-mqs’

If you are on Unix grep the NetConfig to see if “TYPE mqs” exists.  If so figure out which thread.  Several ways.  I would edit NetConfig using vi or whatever and find the string “TYPE mqs”  the just go back to next instance of “protocol”  You should see something like “protocol Thread Name {”

Then simply go to NetConfig GUI and fix it

If not in your NetConfig you need to contact Infor Support
