Problem: Product Name: VisiBroker for C++ Product Version: 8.0 Product Component: Marshaling Platform/OS version: All You have encountered this exception sporadically. org.omg.CORBA.MARSHAL: Invalid TypeCode offset: 84/-40 vmcid: 0x0 minor code: 0 completed: No or System exception `MARSHAL"Locality: exception has been generated locally Completed: maybe Minor code: 0x4f4f0026 (invalid TypeCode indirection= ) You would like to know why it occurs and how to resolve it. Resolution: In GIOP 1.0, when the client is invoking the server passing in a few parameters with the same data type, the client orb will marshal and stream the bytes to the server. An example of the idl structure is shown below Module Bank{ interface Account { float balance(); }; interface AccountManager { void addAccounts (in array acctlist); }; }; If the client is executing the addAccounts function in the Bank::AccountManger class with 3 Accounts objects in the array, a simple illustration of how the client orb will marshal the data is shown below GIOP Header Request Id Type code for Array Type code for Any Value for Any Type code for Any Value for Any Type code for Any Value for Any Subsequently, the CORBA specification introduces type code optimization to reduce the length of the GIOP request in GIOP 1.2. Similar data structure will be marshaled as follows: GIOP Header Request Id Type code for array Type code for Any Value for Any Pointer to Type Code for Any Value for Any Pointer to Type Code for Any Value for Any A CORBA.MARSHAL exception has occurred because the offset is wrong and point to an invalid type code in the input buffer. You need to disable type code optimization in both client and server. Set the property " vbroker.orb.topLevelTCIndirection=3 " to turn off the Typecode optimization. Alternatively, you can also apply " vbroker.typecode.noIndirection=true " to disable all Typecode optimization. When you apply this property, the property " vbroker.orb.topLevelTCIndirection " will be disabled. References Backward Compatibility Issue with VisiNotify 6.5 using Typecode optimization
