Hi All
Below is a description of our project, followed by the problem.
Brief Description:
In our project, we have a MQSI flow deployed on Sun Solaris (UNIX) environment that sends messages to a Java adapter( a java program) residing on AS/400. The Java adapter parses the received message, extracts a service request, gets the request data from DB2 and then sends a message back to the MQSI with the requested data in the form of a XML String. The data contains both character and numeric.
From the MQSI on Solaris, we are adding a RFH2 header to the message before it is sent to the AS/400 box. The Java adapter ignores the header, and simply adds the same header to the reply message.
Problem:
When MQSI Request flow sends the request message to adapter it sets the CCSID to 819. Java Adapter is able to read the message and can parse it as well. After processing the request, Java adapter sends the response back to MQSI Reply flow but with CCSID of 32 (Native to MQ Queue manager on AS/400), and when MQSI reply flow receives the response and tries to parse it for getting business specific information, the flow throws parsing exception.
But, currently we have made a temporary fix. That is, in the Java adapter code, we are setting(hardcoding) the CCSID to 819 before PUTting the message. The MQSI flow will then not throw any exceptions! And we want to avoid hardcoding, if at all possible.
We have tried converting the message on request and reply flows and also tried conversion on MQ channels but all options have failed.
We have tried the following without any success.
Set CCSID on both sides to respective codepages, (all sorts of combinations)
Changed the encoding, etc,
Tried keeping CONVERT "ON".
Set Format to String.
Are we missing something? Can you please help us solve this?
Thanks in advance.
Anil. |

Unless you really don't want to.... Make sure that the get with convert option is specified in your MQInput node. This should force MQSeries to do the convert for MQSI on the return.
It sounds like you have looked at the message when sitting on the Solaris queu emanger and verified the CCSID that was sent from AS400... I suppose that it is possible that a conversion page from 32 -> 819.. In this case MQ would not be able to transalate the message... If it were a missing conversion page then I would expect a error message to be thown at the application layer or by MQ.
Just a thought. |

yes, we have lookied at the conversion pages and they are there.....and we have tried with channel conversion "on" in the solaris side.....still does not beat the problem.
cant see what we are not doing logically!
