Hi,
I'm trying to receive a string with double byte characters from a Mainframe (EBCDIC). We are using CodedCharSetId = 5026 on the mainframe end. And at the receving end (Windows NT system) MQGMO_CONVERT to do the ASCII/EBCDIC conversion and setting the MQMD CodedCharSetId to 5026. The conversion is not happening. Infact the normal single byte characters (Which was working fine with the MQGMO convert) goes for a toss after I made the above change. Only, characters in their Hex values was received properly at the client end.
The trace of the received message looks something like this:
MQOPEN - 'Test'
StrucId : 'MD ' Version : 2
Report : 0 MsgType : 8
Expiry : -1 Feedback : 0
Encoding : 785 CodedCharSetId : 5026
Format : 'MQSTR '
**** Message ****
length - 75 bytes
00000000: F1F2 F3F4 F540 7B5B 6C50 C1C2 C3C4 C531 'ñòóôõ@{[lPÁÂÃÄÅ1'
00000010: 3233 3435 2023 2425 2641 4243 4445 F000 '2345 #$%&ABCDEð.'
00000020: 0000 0000 0000 0000 0000 0000 0000 0000 '................'
00000030: 0000 0000 0000 0000 0000 0000 0000 0000 '................'
00000040: 0000 0000 0000 0000 0000 00 '........... '
Can you please let me know, what I'm missing or what I need to do to get double byte characters properly.

You mentioned "And at the receving end (Windows NT system) MQGMO_CONVERT to do the ASCII/EBCDIC conversion and setting the MQMD CodedCharSetId to 5026. " If the MQMD CCSID is being set to 5026 and the message is already 5026, then no conversion is needed. I may have misunderstood your above statement, but if not, try using the value for "MQCCSI_Q_MGR" (low values) instead of 5026 in the CCSID field of the MQMD before the MQGET. This should cause the Conversion to take place.
The following is from the Application Reference:
If the MQGMO_CONVERT option is specified on the MQGET call, this field is an input/output field. The value specified by the application is the coded character-set identifier to which the message data should be converted if necessary. If conversion is successful or unnecessary, the value is unchanged (except that the value MQCCSI_Q_MGR or MQCCSI_INHERIT is converted to the actual value). If conversion is unsuccessful, the value after the MQGET call represents the coded character-set identifier of the unconverted message that is returned to the application. |
