Hi,
We have migrated a server from AIX to HP which hosts MQ Sever.
An application on z/OS puts a message to a local queue on the HP server. An application on HP polls the queue and sends a response back to the mainframe queue manager. However, the application on the mainframe doesnt recognise the message since the migration. All worked fine previously.
No message conversion takes place
All messages sent/received are in ASCI
Would be gratefulf if someone could point me in the right direction
Thanks in advance |

Would you please explain more about what is "wrong" with the message when it arrives at the mainframe? |

What i meant is that the application doesnt recognise the message format.
I think it expects the response in ASCI but AIX version of ASCI but now that we have migrated the response is sent back in HP version of ASCI
Could the above be a possibility? |

It's possible. There are several ASCII codepages.
If you need more than "it's possible", please supply details of what is "wrong" with the message when it arrives at the mainframe.
Question: if the message contents are pure ASCII text, then could you tell MQ the message is MQFMT_STRING when putting it on the HP-UX machine, and use MQGMO_CONVERT on the mainframe's MQGET call? |

Actually this may not please your mainframe admins, because MQGMO_CONVERT causes extra processing on the MQGET. Mainframe owners are usually very careful with their MIPS so they may not be happy to use MQGMO_CONVERT. |

Hi,
We are setting MQFT_STRING when putting it on the HP-UX machine. However, we dont use MQGMO_CONVERT on the mainframe's MQGET call.
It has also worked fine previously...No application or MQ infrastructure changes have taken place. The only change in the architecture is the OS change from AIX to HP-UX.
I have noticed that the CCID are different bwteen the two platforms
HP-UX
CCSID(1051)
AIX
CCID(819)
I think I will alter the CCID on the queue manager on HP-UX machine to use CCID(819) |

So your saying the mainframe app produces ASCII request messages, and expects reply messages in ASCII as well?

Looking at a dog and calling it a duck is not gonna make it quack.

.....and did the old AIX channeldo the conversion new one not by any chance? Or were the defintions identical? |
