How can I set the PDQPRIORITY for every user in the database?
I am also trying to get Xtree to work on the same system so I can better analyze user queries but can't figure out how to do that either.
Set your PDQPRIORITY in your oninit file. It's the main set of parameters for each Informix instance. It's usually in the $INFORMIXDIR\etc directory and is usually called oninit******.
