We would need your help.

When we test using the actual HL7 message, how could we achieve to send the response from the Process to the Service? 

Process does not send response to a EnsLib.HL7.Service.TCPService when we test it with a EnsLib.HL7.Operation.TCPOperation, why?

We are developing a Production which is composed by:

 - A service: EnsLib.HL7.Service.TCPService

 - A bussiness process

 - An Operation: EnsLib.HL7.Operation.TCPOperation


We have the following challenge:

I would like to create a new message of a particular type and append various segments programmatically.  I have started with the following snippet.  What I am currently finding difficult is to define a segment of a particular segment structure.  I would like to append a pid segment of 2.3.1 to my message.  I know I could you the importfromstring but I wanted to know whether there was a better way of achieving this.

FHIR Terminology Service specification describes a set of operations on CodeSystem, ValueSet and ConceptMap resources. Among those operations, the following four operations appear to be the most widely adopted ones:

CodeSystem ValueSet

Developing a partial implementation of the specification has been an effective way to explore the new FHIR framework introduced in IRIS for Health 2020.1. The implementation includes four operations listed above, and supports read and search interactions for CodeSystem and ValueSet resources.

It's important to note that the implementation uses plain ObjectScript persistent classes as source terminology tables.

I was wondering if there was a certain procedure or documentation on securing (Https://) the Web Portal into IRIS/Ensemble?

Currently we are using LDAP Delegated Authentication to access the Web Portal using LDAP. However as more and more emphasis is put on securing applications within networks, I can see Management/Security asking us to make sure that the web portal is more secure.

Let's imagine if you would like to write some real web application, for instance, some simple clone of Such sort of application can be written using any different language on the backend side, or with any framework on the frontend side. So many ways to do the same application, and you can look at this project. Which offers a bunch of frontends and backends realizations for exactly the same application. And you can easily mix them, any chosen frontend should work with any backend.

Let me introduce the same application realization for InterSystems IRIS on a backend side.

Hello, we would need some help:

We would like to use a Transformation to convert an ORU_R30 2.3 to ORU_R30 2.5

However Ensemble does not have a HL7 Schema for ORU R_30 2.3

So then our original message is not being recognized:

→ How could we let Ensemble recognize the ORU R30 2.3 structure to be able to use a Transformation?

We have read:

Hi, I am new to IRIS and We are planning to setup a CI pipeline on AWS VM deploying the iris data platform container. I am trying to find out which folders needs to be inside the source control and where (exact folder) the updated code needs to be pulled in the container. I would be much obliged if anyone cant point the CI CD related documentation.

File Passthrough Feeder

IRIS Interoperability Productions formerly known as Ensemble are fun to work with. Yes, I really think my work is fun. I have seen File Passthrough Services and File Passthrough Operations come in handy. At one point we placed test messages in files, then we utilized a File Passthrough Service with Inbound File Adapter to send the contents of the file as a Stream to a File Passthrough Operation with Outbound TCP Adapter.

If a global node contains special characters, (eg : a line returns), it will be displayed like this in Portal ("System > Globals > View Global Data" panel) :

^A(1) = "this is"_$c(13,10)_"a test"

I would like to export global data to a txt file using a similar format.

I already wrote the main code (that loops on all nodes and dump them to file), the problem is how to handle special characters.
For the moment I replace them manually one by one. It works, but it's far from perfect :

How do I run a CSP page from within VS Code.

Secondly I have installed an extension called "Live Server" which will run .html pages within VS Code. Have any of you made use of this extension and if so can you specify that .csp pages are html pages?

If I press F5 in VS Code (just as you would in Cache Studio) in order to view a csp page when I press F5 in vs code it tries to open


without the csp page name

Using Grafana directly from IRIS

There have been some very helpful articles in the community that show how to use Grafana with IRIS (or Cache/Ensemble) by using an intermediate database.

But I wanted to get at IRIS structures directly. In particular, i wanted to access the Cache History monitor data that is accessible by SQL as described here

and didn't want anything between me and the data.

I want to check patient class in multiple rules, since the message structure is different to reach out to patient class value, i created a method to get the patient class and put it in a variable. This variable i can use in multiple rules. But somehow function is not able to read the HL7 message. Any tips.

In rules i have this assign line.

We would need your help:


We are processing a HL7 message.

Its OBX segment has 4318 characters


1) We get the OBX with the following line of code:

set textoCompleto = request.GetValueAt("5:3.2")


When we output its length with:

$$$LOGINFO("textoCompleto: "_textoCompleto)


It shows:

     $LENGTH(textoCompleto): 3497


 - So as we see it is being shortened
