我正在使用 Message Broker 8 和 MQ 7。当我尝试在我的消息流中使用映射节点时，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：

            )
          )
        )
      )
    )

整个消息流运行良好。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给出相同的错误。我不知道可能是什么问题。也许是 JRE 错误？

任何想法？

谢谢！

这很可能是由于 64 位机器上的 Java 堆大小较大，因为所有引用都大了 4 个字节。要使其工作，您可以简单地在 32 位代理上运行它或尝试以下任何一种方法 -

  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) 在代理提示符下执行以下命令

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

b) 验证 JVM 选项是否成功应用

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

系统应显示 -

-Xcompressedrefs

c) 重启执行组

  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 JVM 选项是否成功应用

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

c) 重启执行组

希望这可以帮助
