爲什麼映射節點獲取java.lang.RuntimeException？

Question

我正在使用Message Broker 8和MQ 7.當我嘗試在消息流中使用映射節點時，我得到一個java.lang.RuntimeException。

以下是事件查看器顯示：

(BROKER8.default) The map script generation for QName ''{practica}:CambioFecha'' has failed, with the following details: ''java.lang.RuntimeException: ''. 

The generation of the map has failed. 

Review and resolve the problems indicated in the message from the map generation. 

完整的異常堆棧是：

    ' (CHARACTER) 
      ) 
     ) 
     ) 
    ) 
    ) 

整個信息流是工作的罰款。所以，我認爲這不是映射節點的錯誤。另一個細節，在其他流程中，映射節點完全不起作用，並給出相同的錯誤。我不知道可能是什麼問題。也許是一個JRE錯誤？

有什麼想法？

謝謝！

Answer 1

這是最可能是由於在64臺機器的大Java堆大小，因爲所有的引用是較大的4個字節。要使其工作，你可以簡單地在32位經紀人運行或嘗試以下任一 -

1. 使用Xcompressedrefs（關於它的解釋是在這裏 -

http://publib.boulder.ibm.com/infocenter/javasdk/v6r0/index.jsp?topic=%2Fcom.ibm.java.doc.diagnostics.60%2Fdiag%2Funderstanding%2Fmm_compressed_references.html）

一）在代理提示

mqsichangeproperties來--broker名稱 - -e --EG名稱 - -o ComIbmJVMManager -n執行以下命令jvmSystemProperty -v \ 「 - Xcompressedrefs \」

b）中驗證的JVM選項成功地應用於

mqsireportproperties --broker名稱 - -e --EG名稱 - -o ComIbmJVMManager -n jvmSystemProperty

該系統應顯示 -

-Xcompressedrefs

c）重新啓動執行組

1. 增加JVM存儲器，默認是256MB a）執行以下命令

mqsichangeproperties來--broker名稱 - -e - EG名稱 - -o ComIbmJVMManager -n jvmMaxHeapSize -v 536870912

b）中驗證的JVM OPTIO n被成功地應用於

mqsireportproperties --broker名稱 - -e --EG名稱 - -o ComIbmJVMManager -n jvmMaxHeapSize

c）重新啓動執行組

希望這幫助
