Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data. This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client. This has had me scratching my head in so many ways.

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Some background

I'm creating a Business Process that:

  1. Transforms one object into another using DTL
  2. Sends this object to an operation
  3. Transform the object obtained in first point into another one using DTL
  4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

I have tried to make transformation before making CALL's, I mean:

Is it possible to use one IIS server to configure Webgateway and external Webserver for management portal when implementing synchronous mirroring with VIP i.e Is it necessary to have two mirror servers(primary and Backup) , one Arbiter server, one Webserver for Webgateway and a sperate webserver for management portal?

If anyone can please point to any documentation on Mirroring with Webgateway and external webserver for management portal will be really helpful.

Thank you for your help

Background:

This guideline provides an overview of how to design and implement a REST API interface for querying patient demographic data from an Electronic Patient Record (EPR) system using HealthConnect. The process involves sending a query request with the patient's identification number, retrieving the response from the EPR system, extracting the required patient demographic data from the HL7 message, and sending it as a JSON response to the supplier. The high-level process diagram is shown below (Screenshot 1).

Intersystems provides External language server connections for various languages which,
from a development perspective, is great as I can keep my application code separate but still interact with the IRIS kernel.

It becomes more complex though if you are using Interoperability etc where you might end up with some code in IRIS and some code in another language.

What would be great is having an IRIS to IRIS language server where the application code and stay IRIS based but separate from the database?

When we create a FHIR repository in IRIS, we have an endpoint to access information, create new resources, etc. But there are some resources in FHIR that probably we wont have in our repository, for example, Binary resource (this resource returns a document, like PDF for example).

I have created an example that when a Binary resource is requested, FHIR endpoint returns a response, like it exists in the repository.

Since .Net has a unified package manager system (Nuget.org) why doesn't Intersystems create and add a nuget package (.nupkg) containing the InterSystems.Data.IRISClient.dll file.

This would make it easier for external .net developers to obtain the package for creating tools and/or applications that utilize Iris/Iris4Health

Can Intersystems create a nuget package?

We connect to MS SQL Databases using the Microsoft JDBC Driver 12.2 using the following URL

jdbc:sqlserver://<server>:<port>;database=<database name>;trustServerCertificate=true;integratedSecurity=true;authenticationScheme=NTLM;domain=osumc;authentication=NotSpecified

They want to migrate the databases to the Azure Cloud and in doing so we need the Authentication to change to go through Microsoft Entra. I was given the following URL

How to create a signed JWT

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2Guide

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

Epic had changed some of their logic on their Incoming Radiology Results which now require an Ordering Provider even though it is supposed to account for it within the Epic Interface settings.

I was wondering if we are using a custom schema if there was a way to default a value into OBR:16 if it was not valued without having to modify all the DTL's for these Results.

Is there a way to set this via the schema editor or in the background so we don't have to create/update DTL's or create a custom TCP Operation Class??

Hello, Does the NodeJs package work when running a node js file on windows (nodejs for windows)? I've added the package by running npm install <package location folder>

I have the following index.js file, but when running from node (windows) I get the following error. Does the NodeJs package build the output files when the package is added or does it just assume linux as the underlying os?

Error: Cannot find module './bin/winx64/irisnative.node'

Been testing out the Production Validator toolkit, just to see what we can/not do with it. Seems really interesting and there seem to be some use cases for it that can really streamline some upgrades (or at least parts of upgrades) but I was running into so many hurdles with the documentation. I am curious if anyone else has used it.

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation. Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation?

Hello Community,

This article aims to walk you through the process of setting up and utilizing the Flexible Python Runtime Feature for embedded Python. Prior to version 2024.2, Intersystems IRIS installer included a preinstalled version of Python, You can find the Python libraries and application files located in the \lib\python directory within your IRIS installation folder (for example, C:\InterSystems\IRIS20242\lib\python).

I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

I have VS Code with extensions connected to IRIS for Health. One top-level ObjectScript package is not displayed in the workspace for this namespace. This package exists in the namespace and is visible in SMP. If I create a new class with a different top-level package name (package that didn't previously exist) it will immediately appear in the workspace.

Is there any debug logging I can enable to look for errors or do any other troubleshooting?

Forgot to mention: the missing package is custom, not a system package.
