When I connect to my database I get the error:
"DB2 LUW connections are not currently licensed."
I did not buy Toad for ZOS.
Toad for DB2 will accept half a license key without prompting an error. As a result, this issue is caused by not entering in the full license key.
Make sure you have the original license email sent by Quest Licensing and make sure you type in the full key.
Waiting for fix in a future release of Toad for DB2.
