Your Global Settings are exactly that. They effect every listener profile that you create, and they must be correctly configured before you can add or edit processing profiles, or RUN any profiles that you have already created.
Section 1: Saving HL7 Acknowledgements.
As your HL7 Listener(s) are receiving messages they will most likely (unless you specifically configure them not to) send back a HL7 ACK (acknowledgement). This is a standard feature and typically there is no reason for you to need to save them physically. You can always look at your daily Traffic Logs to see what type of ACK your listener returned for each message received, and the traffic logs are much easier to search through than a file of raw HL7 ACK messages.
If you do wish to archive them just check the box and click OK to save.
Section 2: System Log Level
You can select the log level here. There are only 3 options and they basically equate to minimum, medium, and maximum. These log files can be found in the \Logs sub-folder of the installation folder.
Section 3: File Maintenance
Select how long log files and archives should remain on the file system before the program deletes them. When your profiles are running (either Locally or as a Windows Service) they spawn a file maintenance thread periodically which will delete log files or archives that are older than your selection here which were created by the profile. The files and folders purged are:
•The Traffic sub-folder of the Data Folder in the profile.
•The Logs folder which is a sub-folder of the folder where the software is installed.
•IMPORTANT. File Maintenance will NEVER delete HL7 data files in your Data Folder or Malformed messages in the Malformed sub-folder.
NOTE: Make sure that you restart your windows service(s) after making changes to your Global Settings.
