Oracle : Ошибка ORA-28521

"no heterogeneous capability information available"
*Cause: The ORACLE server's data dictionary did not contain
capability definitions for the connected non-Oracle system,
and automatic self-registration (data dictionary upload)
was disabled.
*Action: Ask a DBA to resolve this problem. The easiest resolution is
to enable automatic self-registration by setting the ORACLE
server's HS_AUTO_REGISTER initialization parameter to TRUE.
An alternative is to load the Heterogeneous Services
data dictionary with information specific for the non-Oracle
system by executing a SQL script supplied by the agent vendor.
If the script is run and the error persists, contact the
customer support representative of the agent vendor.
