Elements of a Routing Production
PassThroughMessageTypes
A comma-separated list of message types that are exempt from duplicate checks, sequence
checks, or output transformations. The sequence manager always passes these messages
through unchanged. The default list is:
QBP_Q21,QBP_Q22,RSP_K21,RSP_K22,ACK
PerformOutputTransformationOn
Fields for the sequence manager to transform before sending out a message. The output
transformation provides new facility, application, and sequence number fields as described
in the following list, then sends the message to its configured targets. Possible values for
PerformOutputTransformationOn are:
• Sender — This is the default. The sequence manager copies Facility and Application
from the OutputFacilityApplication setting and assigns a new sequence number. The result
is that the following fields are changed in the outgoing message:
- MSH:3 SendingApplication
- MSH:4 SendingFacility
- MSH:13 SequenceNumber
• Receiver — The sequence manager copies Facility and Application from the Output-
FacilityApplication setting and assigns a new sequence number. The result is that the
following fields are changed in the outgoing message:
- MSH:5 ReceivingApplication
- MSH:6 ReceivingFacility
- MSH:13 SequenceNumber
• None — The sequence manager does not perform any transformation before sending the
message.
PerformSequenceNumberCheckOn
Fields for the sequence manager to check to see if any of the incoming messages are out of
sequence. If so, the sequence manager resequences the messages and sends them to its configured
targets.
Possible values for PerformSequenceNumberCheckOn are:
• Sender — This is the default. The sequence manager checks:
- MSH:3 SendingApplication
- MSH:4 SendingFacility
