Question

我在尝试在计算节点中添加MQMD标头时遇到了麻烦。试过这样的事情：

SET OutputRoot.Properties = InputRoot.Properties;
CREATE LASTCHILD OF OutputRoot DOMAIN('MQMD') NAME 'MQMD';
SET OutputRoot.MQMD.Format =  MQFMT_NONE; 
SET OutputRoot.MQMD.CodedCharSetId = 1208;
SET OutputRoot.MQMD.Encoding = 546;

但它始终以此例外结束：

Text:CHARACTER:Caught exception and rethrowing
Insert
Type:INTEGER:14
Text:CHARACTER:test.MyAdp.AddHeader
RecoverableException
File:CHARACTER:F:\build\slot1\S900_P\src\CommonServices\ImbValue.cpp
Line:INTEGER:989
Function:CHARACTER:ImbValue::stateError
Type:CHARACTER:
Name:CHARACTER:
Label:CHARACTER:
Catalog:CHARACTER:BIPmsgs
Severity:INTEGER:3
Number:INTEGER:2329
Text:CHARACTER:Value not valid

当然，如果不添加MQMD标头，一切都运行良好。我尝试使用其他格式作为MQFMT_STRING，MQFMT_RF_HEADER_2（接下来添加了MQRFH2标头），但结果相同。

任何人都可以给我任何线索吗？是否有可能以某种方式从经纪人处获得更有意义的诊断？

UPD 这是在进入计算节点之前跟踪，该节点尝试添加MQMD标头。永远不会到达Compute之后的跟踪节点。

UPD2 以下是用户跟踪的片段，从创建MQMD的计算节点返回后，消息立即出现在try-catch节点中。

Answer 1

“属性”文件夹中的某些属性可能会意外为空。将它们复制到MQMD文件夹时会出现此问题。用户或系统跟踪将显示哪一个。

您的问题是否与超时通知节点有关？我遇到了Properties.CreationTime = null的问题我看到其他人遇到了Properties.Topic = null

的问题

我把它编码为绕过这个问题。

Answer 2

您是否尝试将格式设置为字符值？根据文档，这是预期的：

http://www-01.ibm.com/support/knowledgecenter/SSMKHH_10.0.0/com.ibm.etools.mft.doc/ad09700_.htm

即/

SET OutputRoot.MQMD.Format =  'MQFMT_NONE';

Answer 3

你有没有尝试过改变？
CREATE LASTCHILD OF OutputRoot DOMAIN('MQMD') NAME 'MQMD'; 与

CREATE LASTCHILD OF OutputRoot DOMAIN('MQMD');
无需指定名称
