HI,
When setting last message in group by:
| Code: |
SET OutputRoot.MQMD.MsgFlags = MQMF_LAST_MSG_IN_GROUP;
|
the actual value in MsgFlags is 16.
When this is done with rfhutil by checking Group [YES, LAST] on the tab MQMD it is 24.
According to this:
http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/index.jsp?topic=/com.ibm.etools.mft.doc/ac25710_.htm
it is enough to set MQMF_LAST_MSG_IN_GROUP which is 16 I think.
Setting MQMF_MSG_IN_GROUP + MQMF_LAST_MSG_IN_GROUP would give 24 which gives rfhutil.
Could someone tell what value should be in MsgFlags that marks message in the group as last message?
16?
24?
or both are correct? |

The flags are a bitmask
so to be technically correct, you should OR the two values
From the WMQ cmqc.h file
| Code: |
define MQMF_MSG_IN_GROUP 0x00000008
define MQMF_LAST_MSG_IN_GROUP 0x00000010

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Yes,
| Code: |
SET OutputRoot.MQMD.MsgFlags = MQMF_MSG_IN_GROUP || MQMF_LAST_MSG_IN_GROUP |
will give 24 |

Adding or Or'ing will give 24, of course.
The question remains - what should be set by the Putting application?
The IBM manual implies only one of the two flags need be set.
However if you look for value 24 you are checking for both being set.
The correct approach is to check for the flag for last, using AND logic.
If Flags AND Flag_for_last = true then LAST MSG
That way it will work for any combination that includes the LAST flag. |
