The Duplicate Message ID adapter command (
-DID) must also be specified. The
Number of Messages adapter command (
-NM) concatenates the specified number
of messages into a single buffer returned for mapping.
When the Number of Messages adapter command (
-NM) is used, the message
cursor is not returned to the head of the queue for other source cards in the same
map that use the identical queue manager and queue. Multiple source cards of a
single map will not be able to access the same messages retrieved with the
Number of Messages adapter command (
-NM).
Equivalent adapter functionality can be achieved with the Quantity (
-QTY) adapter
command.
