SYSTEMS INTEGRATION QUESTIONS HIGH
YIELD A+
◉ What are two ways that interface messages are sent and received
Answer: TCP/IP with an interface engine is the most common.
Interconnect is used for HTTPS or other communication outside
your local network
◉ What does it mean for an interface to process a message?
Answer: the incoming interface's Filer Daemon tries to find the
correct patient and file the data in the message into Chronicles
the outgoing interface's Event Daemon creates an HL7 message,
based on information in Chronicles, and sends it out through the
port defined in the Comm Daemon.
◉ Are messages ever manually deleted from the Data Queue?
Answer: No, never. They are purged only by an automated purge job.
◉ Communication Status (Interface Monitor Column)
,Answer: whether the comm daemon is stopped or running
◉ Total Recv'd/Sent (Interface Monitor Column)
Answer: total number of messages sent (outgoing) or received
(incoming)
i.e. count
◉ Last Recv'd/Sent (Interface Monitor Column)
Answer: Number of the Last message sent (outgoing) or received
(incoming)
i.e. message number
◉ Time since last message( Interface Monitor Column)
Answer: Elapsed time since a message was last sent (for an outgoing
interface) or received (for an incoming interface)
◉ Queued Messages (Interface Monitor Column)
Answer: number of messages waiting to be sent (outgoing) or
processed (incoming)
◉ Queued Events (Interface Monitor Column)
,Answer: number of events waiting to be processed from the Event
Queue (outgoing only)
◉ Waiting Messages (Interface Monitor Column)
Answer: Number of messages waiting to be processed from the
Holding Queue
◉ Filer/Event Status (Interface Monitor Column)
Answer: Whether the Event Daemon (outgoing) or Filer Daemon
(incoming) is stopped or running
◉ Background Monitor
Answer: takes care of many tasks including determining whether
interfaces are running
◉ Interface Monitor Definition
Answer: Allows you to specify which interfaces should be displayed
in the Interface Monitor activity
◉ Interface Monitor
Answer: displays the interfaces from the definition. There are
several pieces of information available about each interface
displayed:
-AIP ID
, -Interface
-Queue
-Time since last message
-Total recv;d/sent
-Last recv'dsent
-queued messages
-queued events
-waiting messages
-communication status
-filer/event status
-time since comm start
-time since filer/event start
◉ Message Purging Hierarchy
Answer: 1) Interface Level
2) Background Monitor Level
3) System Default of 30 Days
If purge days are not specified for a given interface, the number of
days in the Background moniotr will be used. When neither of those
purge days are specified, then a system-wide default of 30 days is
used.
