Intersystems IRIS Productions provide a powerful framework for connecting disparate systems across various protocols and message formats in a reliable, observable, and scalable manner. intersystems_pyprod, short for InterSystems Python Productions, is a Python library that enables developers to build these interoperability components entirely in Python. Designed for flexibility, it supports a hybrid approach: you can seamlessly mix new Python-based components with existing ObjectScript-based ones, leveraging your established IRIS infrastructure.

Welcome to the finale of our journey in building MAIS.

• In Part 1, we constructed the agnostic "Brain" using LiteLLM and IRIS.
• In Part 2, we designed the "Persona", mastering Dynamic Prompt Engineering and the ReAct theory.

Now, the stage is set. Our agents are ready, defined, and eager to work. However, they remain frozen in time. They require a mechanism to drive the conversation, execute their requested tools, and pass the baton to one another.

Today, we will assemble the Nervous System.

Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

s r = ##class(User.ADGroup).%New()
s json = {"code": "123", "text":"456", "oazisCode": ["1","2"]}
d r.%JSONImport(json)
w r.oazisCode.

I was having trouble with some dimension based calculated members defined in Analyzer.  They would work and then not work.   At one point I had two identical calculated measures, same code, same specification and one would work and one would not.  I was trying to set them up in "shared storage", that checkbox in the calculated member dialog that should allow the measures to be used across multiple pivots.

Hello,

First of all thanks for your time reading our question, and thanks for your replies and help

We would need to know if a patient has less than 65 years old, using their birthday from the PID 7.1

So far we have developed the following code:

 //19760422 
  set nacimiento             = request.GetValueAt("PID:DateTimeofBirth.Time")
  $$$LOGINFO("nacimiento: "_nacimiento)


  //22/04/1976
  set nacimientoFormateado   = ##class(Util.FuncionesComunes).DateFormatConvertToXML(nacimiento)


  // ""
  set nacimientoFormateado65 = $extract($system.SQL.

Hi communauty

I've two columns in my table and the type must be interval of integer values for example : age must be interval between [2 and 6] years and wigth between [10 and 30 ] Kg , how can i define them when creating my table?

thank's

Hi all,

I've created a method to calculate the age of a person, or the age of a process, contract or other stuff as you want.

/// Calculate the age from date of birth and other date (by default shoud be today).
/// <b>dateOfBird</b> Date of birth in cache format. ie. $ZDH("1972-01-01",3)
/// <b>day</b> Date to calculate to. ie: $H
ClassMethod AgeAt(dateOfBirth, day) As %Integer{
    quit:dateOfBirth=""
    quit:day=""
    
    set yeardob=$SYSTEM.SQL.DATEPART("year",dateOfBirth)
    set yearday=$SYSTEM.SQL.

Hello All,

No matter what I try in Business Process Logic (BPL), I am unable to calculate the patient's age in days or years.

Has anyone ever built logic in a Business Process (BPL) to calculate a person's age in days?

Thank you!

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite select top 10 ID from some_table where row_status in ('I','U') order by ID - the same select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I want to implement isc-rest in my new project iris-budget/module.xml at master · oliverwilms/iris-budget

I get this error:

#8 11.30 Building dependency graph...
#8 12.69 ERROR! Could not find satisfactory version of isc.rest in any repositories. Required by: iris-budget 0.0.1: ^2.0.0
#8 ERROR: process "/bin/sh -c iris start IRIS && \tiris session IRIS < iris.script &&     ([ $TESTS -eq 0 ] || iris session iris -U $NAMESPACE \"##class(%ZPM.PackageManager).Shell(\\\"test $MODULE -v -only\\\",1,1)\") &&     iris stop IRIS quietly" did not complete successfully: exit code: 1
 

In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

I am working on a new project oliverwilms/iris-budget
based on intersystems-community/iris-fullstack-template: This template shows you how to build, test and deploy a simple full-stack application using InterSystems IRIS REST API

I do not understand why I get this error:

[INFO] ...started InterSystems IRIS instance IRIS
[INFO] Executing command /docker-entrypoint.sh iris-after-start ...
[INFO] Create namespace: USER
[ERROR] module 'iris' has no attribute 'system'
[ERROR] Command

Recent versions of IRIS come with Lite Terminal available from VSCode. It's a websocket server, with JSON messaging. Here's how to connect to it from Python:

import websocket
import argparse
import requests
import json


defterminal(host, port, namespace, username, password, command, secure):
    session = requests.Session()
    r = session.get(f"http{"s"if secure else""}://{host}:{port}/api/atelier/", auth=(username, password))
    cookies = session.cookies.get_dict()
    ws = websocket.WebSocket()
    ws.

We use the Caché JDBC Gateway to Oracle and SQL servers to directly invoke their stored procedures from Ensemble. Getting quick, inline data results back are typically handled within the Functions.Library class as a function to wrap the query and format the return appropriately.

But what about more elaborate stored procedures made for posting data without log-jamming a Router?  The operations to construct those data pipelines can get tedious, especially when changes are needed.

Hi Community,

Here we have requirement to process messages min 10 sec delay. Current time it is taking my businessProcess is less than 1 sec.

To implement this requirement , I need to sleep 10 sec in business process custom code.

Could somebody help me to implement delay in BusinessProcess.

Thanks,

Hey everyone,

I'm just seeking some guidance and confirmation on what I'm doing for my production health monitoring.

We utilize Grafana to have reporting/monitoring dashboards and I have made a REST API to query the health of our productions. I believe I have everything figured out except for one thing that I'm uncertain about and that is the Production Item Color indicators:

Is there an easy way of being able to figure out the status of an item with the legend above? Ideally, I'd like to have this data in my JSON response.

Hi developers!

In a method I need to return a result as a dynamic object aka JSON Object. And here is my logic:

Classmethod Planets() as%DynamicObject {

 set val1="Jupiter"
 set val2="Mars"// this doesn't work! cannot compile
 return {"value1":val1, "value2":val2}

}

So I need to do the following:

Classmethod Planets() as%DynamicObject {

 set val1="Jupiter"
 set val2="Mars"
 set result={}

 set result.value1=val1

 set result.value2=val2

 return result

}

The second case works. Maybe I'm preparing the Dynamic Object in the wrong way? Can we just use variables inside JSON?

Hey everyone.

I have a web service which is receiving XML as a stream, and I'm intending to then correlate the stream into an object. Unfortunately I am hitting a road block where the sender places a large chunk of the XML within a cdata block which is then causing the correlate of %XML.Reader to not work.

Hello everyone. I'm currently working on how to implement a solution that makes it possible to include within the response of a BusinessOperation the "RetryCount" for each message.
For Example, we have this message that was retried twice:

This is an HL7.message going through a specific business operation, we did not create a custom one: we used the default implementation EnsLib.HL7.Operation.TCPOperation. This operation should automatically handle retries (infinetely waiting on a response).

can my old account be merged with my new account?

Hi,
I need to create a bundle of synthetic data in order to populate FHIR servers (not mine).

Can I use a predefined ids, or is it possible the one of the servers will not allow using my IDs and replace them with it's automatic numbering?

We will cover core logging as well as tracing techniques.

Hello Team,

I am trying to duplicate the production flow in the Ensemble 2018 but after doing all the steps (like copying same class file, adapter file, process class file) as production, still the flow is not working. The error is that it is not reaching the operation (which is supposed to store the data), it gets stuck in the processes. Additionally, I am also trying to add a logic where in OUL message if the value of code 20061 > 30mg, it should automatically send another order back to service (OML).
