Need to have TCP/IP HL7 Inbound service/adapter just write to file - no persistence anywhere in the engine
Curious if anyone has modified the HL7 TCP/IP Service and adapter class to receive an HL7 message, ACK it, and just dump it straight to a file? I don't want the messages in the engine at all - just receive and dump. Has anyone done this before and have code you're willing to share?
Thank you very much in advance!
Product version: IRIS 2022.2
You could have a 0 day Ens.Util.Purge task running every 5 mins and clearing the production messages. That way you could use only built-in components such as the hl7 tcp service and hl7 file operation
Apologies if too late but I tried the following based on the Non Persistence option used in the EnsLib.HTTP/REST/SOAP Generic classes (also see Accelerate Ensemble)
1. Custom TCP Service Extends EnsLib.HL7.Service.TCPService:
Class Community.NonPersistService Extends EnsLib.HL7.Service.TCPService { Parameter SETTINGS = "PersistInProcData:Additional"; /// Persist data to operations with invocation InProc<br/> /// The default is On. <br/> /// This setting is only used if calling an operation with invocation InProc. <br/> /// If this setting is off then no message headers will be created and message bodies will not be saved.<br/> /// If this setting is off there will be no trace in the message viewer. <br/> /// If this setting is off there will be no retry attempts by the operation - only one attempt will be made. <br/> Property PersistInProcData As %Boolean [ InitialExpression = 1 ]; Method OnInit() As %Status { Set $$$EnsInProcPersist=..PersistInProcData Quit ##super() } }2. Custom HL7 File Operation invoked InProc that is the target of the service
Class Community.InProcOperation Extends EnsLib.HL7.Operation.FileOperation { Parameter INVOCATION = "InProc"; }Note the property description from EnsLib.HTTP.GenericService for PersistInProcData states for synchronous sends but this needs to be removed since not relevant for InProc. Sufficient that InProc target processed via OnMessage.
my mistake the current non persist code does require Sync due to a missing check for no request header created in Ens.BusinessService::SendRequestAsync() [there is such a check in SendRequestSync()]. I'll correct that.
