Microsoft Message Queueing
(MSMQ) transports allow you to send data from system queues to pipelines
for processing.
The format for the MSMQ transport is:
msmq:/qame?concurrency=n
- msmq:/
- Required parameter that indicates the transport method is a MSMQ
queue.
- qname
- Required parameter that specifies the name of the queue to use.
- ?concurrency=n
- This optional parameter enables you to specify the number of incoming
records (a positive integer greater than or equal to 0) that can be
processed simultaneously using the parallel pipeline processing feature.
- The higher the number, the more records are processed simultaneously.
For example, a concurrency of 0 indicates do not process records.
A concurrency of 1 indicates process records one-at-a-time. The default
number of incoming records pulled for this transport is 1, unless
you specify otherwise.
- You should coordinate this setting with the number of pipeline
process threads spawned by the concurrency setting in the pipeline
configuration file or the DEFAULT_CONCURRENCY system parameter group
in the Configuration Console. The pipeline concurrency setting determines
the number of simultaneous pipeline processing threads that begin
when a pipeline is started. If your system is set to spawn multiple
pipeline processing threads for each pipeline started, you might want
to increase this transport concurrency setting so that the pipeline
threads are not waiting for records to process.
Example MSMQ transport
msmq:/examplequeue
Using
this MSMQ transport command, the system reads incoming records from
the MSMQ queue named "examplequeue".
