Gateway Server Settings
Gateway server settings are stored in VistA in the XPAR
area under MD PARAMETERS.
IP Address: Each server must have an IP address.
An IP address is a string of numbers with format: xx.xx.xx.xxx. IP address
of the workstation on which the CP Gateway Service is installed.
Type in the IP Address assigned to the VistA server.
Notify Port: The listening port of the local machine.
The port must be open when sending a message to the workstation. The default
is 8888.
From the Notify Port box, select the number of the port.
Log Level: The level of detail to log in the Windows
Event Viewer for the CP Gateway Service.
- Critical – severe errors only
- Error – critical + errors that cause instability in the
operation of the Gateway Service
- Warning – critical + error + any items captured but allowed
the Gateway Service to continue running
- Detail – critical + error + warning + detailed execution
trail of everything that the Gateway Service does as it processes
HL7 messages
Log Directory: The log file tracks all the background operations
and any problems that occur during processing. This is the directory in
which the CP Gateway Service stores the logs.
Type in the location of the log directory.
The default directory for the log file is C:\
Days to Retain Data: The number of days to allow
processed messages to remain in the log prior to purging. After the number
of days indicated, the data is purged during HL7 Log Cleanup.
- Use the arrows to set the number of days to retain messages.
- Leave the field empty or at 0 to retain the data indefinitely.
CP/Imaging Xfer Directory: This is the directory in which Imaging
stores CP transfer data.
Data Retrieval Mechanism: The method to use for
data retrieval–your data source: VistA Notification or Polling.
Set the interval to VistA Notification. In VistA Notification,
the VistA server will automatically notify the CP Gateway whenever a message
arrives that requires processing. This is the preferred setting. Sometimes,
however, local business requirements dictate that the Polling option
be used. This option acts like the legacy CP Gateway, in that the CP Gateway
will be polled periodically for data to process.
Polling Interval: The CP Gateway Service polls
for new instrument data to transmit to VistA.
When you select Polling as the data retrieval mechanism, use the
arrows to set the number of seconds between polling operations. A new
value becomes effective after the next polling operation.
