"ORACLE and heterogeneous agent are incompatible versions"
*Cause: An operation on a database link attempted to connect to
a non-Oracle system, but the ORACLE instance and the
agent process for the non-Oracle system are incompatible.
*Action: Ask your DBA to confirm configuration of both the ORACLE
instance and the agent. Additional information on the
version incompatibility is logged in trace (*.TRC) files,
the ORACLE instance and the agent, and in the ORACLE
instance's alert log. Check the documentation for your agent
to find out which releases of the Oracle Server are supported.
