This document explains why message CWBSY1008 RC=8007 can be received on ODBC connections for new users only, while existing users are not affected.
Resolving The Problem
Some new ODBC users receive message CWBSY1008 General Security Error RC=8007 when trying to connect. Existing users work without error.
The new users do not have authority to their own user profiles. Once the users are given authority to their own profiles, the connections work without errors.
Note: This problem would also affect other types of System i Access connections in addition to ODBC.
