ORA-28527: Heterogeneous Services datatype mapping error
Cause: Either an Oracle datatype could not be mapped to a non-Oracle datatype, or a non-Oracle datatype could not be mapped to an Oracle datatype. These mappings are defined as capability definitions in the ORACLE server's data dictionary
Action: Verify that the ORACLE server's data dictionary has been initialized with correct capability definitions for the connected FDS_CLASS_NAME and FDS_INST_NAME. If table contents are incorrect, a DBA should restore all data dictionary content for this FDS_CLASS_NAME and/or FDS_INST_NAME. It usually is sufficient to delete all current data dictionary content for this class and/or instance and initiate a new connection to let the connected agent upload new data dictionary content to the server. If the error persists contact the customer support representative of the agent vendor
