ERROR org.omg.CORBA.MARSHAL序列長度太大

Question

成功地從CORBA的網管服務器獲取報警和現在正在閱讀的價值觀，我得到以下

ERROR: org.omg.CORBA.MARSHAL: Sequence length too large. Only 12 available and trying to assign 31926513 vmcid: 0x0 minor code: 0 completed: No 
org.omg.CORBA.MARSHAL: Sequence length too large. Only 12 available and trying to assign 31926513 vmcid: 0x0 minor code: 0 completed: No

錯誤的方法後AlarmInformationSeqHelper.extract

// Get all active alarms list 
private static void getAlarmsList(ORB orb, AlarmIRP alarmIRP) { 
    try { 
     ManagedGenericIRPConstDefs.StringTypeOpt filter = new ManagedGenericIRPConstDefs.StringTypeOpt(); 
     filter.value("($type_name == 'x1')"); // Query new alarms and acknowledge or unacknowledge alarms

     BooleanHolder flag = new BooleanHolder(); 
     AlarmIRPSystem.AlarmInformationIteratorHolder iter = new AlarmIRPSystem.AlarmInformationIteratorHolder(); 
     StructuredEvent[] alarmList = alarmIRP.get_alarm_list(filter, base_object, flag, iter); 
     System.out.println("AlarmIRP get_alarm_list success, flag: " + flag.value + " fetched total: " + (alarmList == null? -1: alarmList.length)); 

     for (StructuredEvent alarm: alarmList) { 
      if (alarm.header != null) { 
       System.out.println("fixed_header.event_type.name: " + alarm.header.fixed_header.event_type.type_name 
         + " fixed_header.event_type.domain_name: " + alarm.header.fixed_header.event_type.domain_name); 
       if (alarm.header.variable_header != null) { 
        for (Property variableHeader: alarm.header.variable_header) { 
         System.out.println("variable_header.name: " + variableHeader.name + " alarm.header.variable_header.value: " + variableHeader.value); 
        } 
       } 
      } 

      if (alarm.filterable_data != null) { 
       for (Property filterableData: alarm.filterable_data) { 
        System.out.println("data.name: " + filterableData.name); 
        if (filterableData.value != null && filterableData.value.toString().contains("org.jacorb.orb.CDROutputStream")) { 
         StructuredEvent[] filterableDataValues = AlarmInformationSeqHelper.extract(filterableData.value); 
        } else { 
         System.out.println("data.value: " + filterableData.value); 
        } 
       } 
      } 
     } 

    } catch (ManagedGenericIRPSystem.InvalidParameter e) { 
     System.out.println("ERROR get_alarm_list InvalidParameter (Indicates that the parameter is invalid): " + e) ; 
    } catch (ManagedGenericIRPSystem.ParameterNotSupported e) { 
     System.out.println("ERROR get_alarm_list ParameterNotSupported (Indicates that the operation is not supported): " + e) ;  
    } catch (AlarmIRPSystem.GetAlarmList e) { 
     System.out.println("ERROR get_alarm_list ParameterNotSupported (Indicates exceptions caused by unknown reasons): " + e) ; 
    } 
} 

或者我的閱讀警報列表的方式不正確？謝謝。

您可以在下面找到了getAlarmList

//Connect to AlarmIRP 
AlarmIRP alarmIRP = AlarmIRPHelper.narrow(orb.string_to_object(alarmIrpIOR.value)); 
StringTypeOpt alarmFilter = new StringTypeOpt(); 
alarmFilter.value(""); 
DNTypeOpt base_object = new DNTypeOpt(); 
base_object.value(""); 
BooleanHolder flag = new BooleanHolder(false); // false for iteration 
AlarmInformationIteratorHolder iter = new AlarmInformationIteratorHolder(); 

List<String> alarmIds = get_alarm_list(alarmIRP, alarmFilter, base_object, flag, iter); 

private List<String> get_alarm_list(org._3gppsa5_2.AlarmIRPSystem.AlarmIRP alarmIRP, org._3gppsa5_2.ManagedGenericIRPConstDefs.StringTypeOpt alarmFilter, org._3gppsa5_2.AlarmIRPConstDefs.DNTypeOpt base_object, BooleanHolder flag, org._3gppsa5_2.AlarmIRPSystem.AlarmInformationIteratorHolder iter) throws org._3gppsa5_2.AlarmIRPSystem.GetAlarmList, org._3gppsa5_2.ManagedGenericIRPSystem.ParameterNotSupported, org._3gppsa5_2.AlarmIRPSystem.NextAlarmInformations, org._3gppsa5_2.ManagedGenericIRPSystem.InvalidParameter, BAD_OPERATION { 
    logger.info("[get-alarm-list][start]"); 
    alarmIRP.get_alarm_list(alarmFilter, base_object, flag, iter); 

    List<StructuredEvent> alarms = new ArrayList(); 
    EventBatchHolder alarmInformation = new EventBatchHolder(); 
    short alarmSize = 100; 
    List<String> alarmIds = new ArrayList(); 
    while (iter.value.next_alarmInformations(alarmSize, alarmInformation)) { 
     alarms.addAll(Arrays.asList(alarmInformation.value)); 
     logger.info("Current alarm size:" + alarms.size()); 
    } 

    for (StructuredEvent event : alarms) { 
     try { 
     //printAlarm(event); 
     } catch (Exception ex) { 
     } 
     List<Property> rem = new ArrayList<Property>(); 
     rem.addAll(Arrays.asList(PropertySeqHelper.extract(event.remainder_of_body))); 
     for (Property property : rem) { 
     if (!property.name.equals(org._3gppsa5_2.AlarmIRPNotifications.NotifyNewAlarm.ALARM_ID)) { 
      continue; 
     } 

     alarmIds.add(property.value.extract_string()); 
     } 
    } 
    logger.info("[get-alarm-list][completed] size :" + alarms.size()); 

    return alarmIds; 
}

我設法弄清楚什麼是filterableData.value.toString()值是「org.jacorb.orb.CDROutputStream」的實例方法。事實證明，根據文檔，名稱爲「b」的房產是TimeBase:: UtcT。

將其轉換爲正確的值，它是一個UTC時間戳記，我改變了條件

if (filterableData.name.equals("b") && filterableData.value != null && filterableData.value.toString().contains("org.jacorb.orb.CDROutputStream")) { 
    long occuranceTime = TimeTHelper.read(filterableData.value.create_input_stream()); 
    System.out.println("data.value: " + occuranceTime); 
}
