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.

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.
