Oracle Solution for Error ora-28560

ORA-28560: error in configuration of agent process

What triggered the Error:

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.

What should we do to fix it:

eck 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 SID. -- Check LISTENER.ORA on the agent's host machine to assure that this SID refers to the correct agent executable in its (PROGRAM=...) clause.
