3.7.2.4.7 Exceptions

If the CORBA object method that is invoked by the client raises an exception, that exception is caught by the TP Framework and is eventually returned to the client. This is true even if deactivate_object() is invoked and raises an exception.

The client will never be notified about exceptions that are raised in deactivate_object(). It is the responsibility of the application code to check that the stored state of the CORBA object is consistent. For example, the application code could save a persistent flag that indicates whether or not deactivate_object() successfully saved the state. That flag can then be checked in activate_object().

If an error occurs while executing deactivate_object(), the application code should raise either a CORBA standard exception or a DeactivateObjectFailed exception If deactivate_object() was invoked by the TP Framework, the TP Framework catches the exception and the following events occur:

  • The object is deactivated.
  • If the client initiated a transaction, the transaction is not rolled back.
  • The client is not notified of the exception that is raised in deactivate_object().
  • Based on which exception is raised, a message is logged to the user log (ULOG) file, as follows:
    TobjS::DeactivateObjectFailed 
    "TPFW_CAT:27: ERROR: De-activating object - application raised 
TobjS::DeactivateObjectFailed. Reason = reason  . Interface =  
interfaceName  , OID =  oid  "
    Where reason is a user-supplied reason, and interfaceName and oid are the interface ID and object ID, respectively, of the invoked CORBA object.
    CORBA::Exception 
    "TPFW_CAT:28: ERROR: De-activating object - CORBA Exception not 
handled by application. Exception ID = exceptionID. Interface =
 interfaceName, OID = oid"
    Where exceptionID is the interface ID of the exception, and interfaceName and oid are the interface ID and object ID, respectively, of the invoked CORBA object.
    Other exception 
    "TPFW_CAT:29: ERROR: De-activating object - Unknown Exception not 
handled by application. Exception ID = exceptionID. Interface = 
interfaceName, OID = oid"
    Where exceptionID is the interface ID of the exception, and interfaceName and oid are the interface ID and object ID, respectively, of the invoked CORBA object.
