Problem:

The user is unable to run or start Oracle instance on Modernization Workbench with a local, non-administrative user.  Oracle is installed with an administrative user, but is now being run by a local user without administrative rights.

Resolution:

The user has to change the following line in the SQLNET.ora file to force Oracle to avoid Authentication and let any user access the database.

SQLNET.AUTHENTICATION_SERVICES = (NONE) (needed for local user access)
SQLNET.AUTHENTICATION_SERVICES = (NTS) (this is the standard default value)

Change the statement to (NONE) and then any user can access the database.
