Changing the SQLNET.AUTHENTICATION_SERVICES

A freshly installed Oracle database sometimes results in ORA-12638 errors. If you are running a dedicated SDL LiveContent Architect Oracle server, you can resolve problems by altering the SQLNET.AUTHENTICATION_SERVICES setting.

  1. Open Oracle file \network\admin\sqlnet.ora
  2. Change the value of parameter SQLNET.AUTHENTICATION_SERVICES to (none). This setting is instead of (NTS).
