MQSeries.net :: View topic - MQHSAP message encoding on Linux needs to be 273? Not 546?

lyntongrice

Hi there,

I have an application the puts messages onto a queue, and sometimes these messages need to have the MQHSAP header.

My understanding is that the encoding for MQ on the different boxes is:

MQENC_* (Encoding)
IBMÂ® i 273 X'00000111'
Linux 546 X'00000222'
UNIX systems 273 X'00000111'
Windows 546 X'00000222'
Micro Focus COBOL on Windows 17 X'00000011'
z/OSÂ® 785 X'00000311'

So from what I understand above Linux wants to use encoding 546.

If I try do an MQPUT on my Red Hat Linux box to MQ 7.1 with a message that has MQHSAP specified I always get the following:

Reason code: 2142
Completion code: 2

That error happens when I do not change the Linux encoding of 546.

If I make the encoding 273 the MQPUT works perfectly.

Also interesting is that if I use the commercial product "MQ Visual Edit" from http://www.capitalware.biz ......if I try insert a message onto a queue on Linux with MQHSAP it ONLY allows encoding 273 as well.....the moment I try *force* the encoding to the Linux default of 546 I get the exact same error...2142...

Why would a tool like MQ Visual Edit default all messages I try INSERT manually onto a queue to 273 if the Linux native encoding is meant to be 546?

Do I need to be concerned on this?

Thanks
