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. 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. 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.
