ORA-28558

Error: ORA-28558: HS_FDS_CONNECT_STRING undefined for non-Oracle system

Causa: A database link to a non-Oracle system had no HS_FDS_CONNECT_STRING initialization parameter in the Oracle server's data dictionary for Heterogeneous Services. Without this parameter, the connection could not be completed.

Acción: Contact your database administrator to verify correct setup of an HS_FDS_CONNECT_STRING entry in the Oracle Heterogeneous Services data dictionary.
