为什么Mapping Node会获得java.lang.RuntimeException？

Question

我正在使用Message Broker 8和MQ 7.当我尝试在消息流中使用Mapping Node时,我得到一个java.lang.RuntimeException.

以下是事件查看器显示的内容:

( 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.

完整的异常堆栈是:

    ' (CHARACTER)
            )
          )
        )
      )
    )

整个消息流工作正常.所以,我认为这不是映射节点的错误.另一个细节,在其他流程中,映射节点根本不起作用并且给出相同的错误.我不知道会出现什么问题.可能是JRE错误？

任何的想法？

谢谢!

Answer 1

这很可能是由于64位计算机上的Java堆大,因为所有引用都大4个字节.要使其工作,您可以在32位代理上运行它或尝试以下任何一项 -

1. 使用Xcompressedrefs(关于它的解释在这里 -

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

a)在代理提示中执行以下命令

mqsichangeproperties --broker name-- -e --EG name-- -o ComIbmJVMManager -n jvmSystemProperty -v \" - Xcompressedrefs \"

b)验证是否已成功应用JVM选项

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

系统应显示 -

-Xcompressedrefs

c)重新启动执行组

1. 增加JVM内存,默认为256MB a)执行以下命令

mqsichangeproperties --broker name-- -e --EG name-- -o ComIbmJVMManager -n jvmMaxHeapSize -v 536870912

b)验证是否已成功应用JVM选项

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

c)重新启动执行组

希望这可以帮助
