Oracle : Ошибка ORA-28560

28560, 0000, "error in configuration of agent process"
*Cause: An ORACLE server invoked a function not supported
by the connected agent (Heterogeneous Services
or external procedures). The most probable cause is
incorrect Net8 setup, resulting in use of the wrong
agent executable.
*Action: Check Net8 administration in the following ways:
-- When using TNSNAMES.ORA or an Oracle Names server, make sure
that the connection from the ORACLE server uses the correct
-- Check LISTENER.ORA on the agent's host machine to assure that
this SID refers to the correct agent executable in its
(PROGRAM=...) clause.
