Oracle Database Errors or Warnings from Error ORA-28558 to ORA-28580
ORA-28558: HS_FDS_CONNECT_STRING undefined for non-Oracle system
Cause: A database link to a non-Oracle system had no HS_FDS_CONNECT_STRING initialization parameter in the ORACLE server’s data dictionary for Heterogeneous Services. Without this parameter, the connection could not be completed.
Action: Contact your DBA to verify correct setup of an HS_FDS_CONNECT_STRING entry in the ORACLE Heterogeneous Services data dictionary.
ORA-28559: FDS_CLASS_NAME is string, FDS_INST_NAME is string
Cause: An associated error was reported in another message, and this message supplies supplementary information to assist diagnosis of that error. FDS_CLASS_NAME and FDS_INST_NAME are used to access information in tables and views of the ORACLE data dictionary that direct operation of Heterogeneous Services on a database link to a non-Oracle data store.
Action: Use the FDS_CLASS_NAME and FDS_INST_NAME values to check ORACLE data dictionary contents when necessary to diagnose the cause of the associated error.
ORA-28560: 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 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.
ORA-28561: unable to set date format on non-Oracle system
Cause: Initialization of a Heterogeneous Services connection to set the date format to be used on the connected non-Oracle system.
Action: If the Oracle data dictionary supplies a value for the HS_NLS_DATE_FORMAT parameter, confirm that this value is formatted correctly by the rules of the non-Oracle system. Also check for additional information in log and trace files generated by the Heterogeneous Services agent.
ORA-28575: unable to open RPC connection to external procedure agent
Cause: Initialization of a network connection to the extproc agent did not succeed. This problem can be caused by network problems, incorrect listener configuration, or incorrect transfer code.
Action: Check listener configuration in LISTENER.ORA and TNSNAMES.ORA, or check Oracle Names Server.
ORA-28576: lost RPC connection to external procedure agent
Cause: of this error is abnormal termination of the invoked “C” routine. If this is not the case, check for network problems. Correct the problem if you find it. If all components appear to be normal but the problem persists, the problem could be an internal logic error in the RPC transfer code. Contact your customer support representative.
Action: First check the 3GL code you are invoking; the most likely
ORA-28577: argument string of external procedure string has unsupported datatype string
Cause: While transferring external procedure arguments to the agent, an unsupported datatype was detected.
Action: Check your documentation for the supported datatypes of external procedure arguments.
ORA-28578: protocol error during callback from an external procedure
Cause: An internal protocol error occurred while trying to execute a callback to the Oracle server from the user’s 3GL routine.
Action: Contact Oracle customer support.
ORA-28579: network error during callback from external procedure agent
Cause: An internal network error occurred while trying to execute a callback to the Oracle server from the user’s 3GL routine.
Action: Contact Oracle customer support.
ORA-28580: recursive external procedures are not supported
Cause: A callback from within a user’s 3GL routine resulted in the invocation of another external procedure.
Action: Make sure that the SQL code executed in a callback does not directly call another external procedure, or indirectly results in another external procedure, such as triggers calling external procedures, PL/SQL procedures calling external procedures, etc.
