MsgSeqNumber (MQLONG)
This is the sequence number of a logical message within a group.
Sequence numbers start at 1, and increase by 1 for each new logical message in the group, up to a maximum of 999 999 999. A physical message that is not in a group has a sequence number of 1.
- On the MQPUT call, MQPMO_LOGICAL_ORDER is specified.
- On the MQGET call, MQMO_MATCH_MSG_SEQ_NUMBER is not specified.
MsgSeqNumber
is
set to an appropriate value.On input to the MQPUT and MQPUT1 calls, the queue manager uses the value described in Physical order on a queue. On output from the MQPUT and MQPUT1 calls, the queue manager sets this field to the value that was sent with the message.
On input to the MQGET call, the queue manager uses the value shown in Table 2. On output from the MQGET call, the queue manager sets this field to the value for the message retrieved.
The initial value of this field is one. This field is
ignored if Version
is less
than MQMD_VERSION_2.
