Hello Developers,

I have MacBook Pro M3 and I'm new to the IRIS for Health setup / installation with all pre-requisite / requirements so someone could please help me with detailed instructions on how to setup IRIS for Health (HL7 & FHIR) from scratch along with SQL Server? I have Windows 11 installed in parallel desktop if that's required and complete installation / setup is not possible on MacBook.

Thank you in advance.

Rushi

Hi everyone,


I'm currently testing out IRIS 2024.3 for a new project, and it's been running smooth for the most part. However, I noticed that when running some heavier analytical queries, the memory usage spikes more than I expected, even when result sets aren’t that large.

I’ve gone through the basics (buffer sizes, query plans, etc.), but I’m wondering if there are any new tweaks or recommended settings in 2024.3 specifically for managing memory better during these peak loads.

Anyone else run into something similar or have tips to fine-tune this?

I deployed an IRIS REST application using Installer class. I think I created the namespace FEEDER database with %DB_Default resource and I used the same resource in Web Application roles. I allowed Unauthenticated Authentication method. I used ^%ISCLOG and reviewed ^ISCLOG. I do not understand why I get 403 Forbidden response.

I have been trying to get to grips with the new dot Net Gateway used in IRIS as the import of the DLL to construct proxy classes is no longer supported in IRIS I have a third party DLL that when I try to instantiate throws an error complaining about the class not instantiated as it does not support parameterless constructor .I am using this new

REST API Issue

I have a rest API Class used for getting data from Cache 2018 version.
I have single route '/callfuntions'
I send the following parameters to the API :- className, methodName, params
I use $CLASSMETHOD to execute and send the result back to the client.

If I make more that 10 to 12 requests in quick succession, then it stops sending data.

Hello,

When setting up a new web app in iris (iris is in a container) iris complains that a WSGI framework is not installed. I have installed python into the container as well as both flask and django via the python virtual environment (see second screenshot) and the python language server is running

Is this the wrong way to install flask? How do I get the container version to recoginize that flask is installed?

XDBC memory leaks

I have a business service that actively reads data from a remote Postgres database. OnProcessInput opens a XDBC (actually JDBC) connection, executes an SQL query, fetches several thousand rows, iterates the resultset, and closes the connection. On each iteration I also need to update each source row in the remote database using PreparedStatement.

In other words, in every OnProcessInput call I have a long running SELECT statement and several thousands small UPDATE statements.

The problems I'm facing are:

Vector Search Performance

Test Objectives

InterSystems has been testing Vector Search since it was announced as an “experimental feature” in IRIS 2024.1. The first test cycle was aimed at identifying algorithmic inefficiencies and performance constraints during the Development/QD cycle. The next test cycle used simple vector searches for single threaded performance analysis to model reliable, scalable and performant behaviour at production database scale in IRIS, and performed a series of comparative tests of key IRIS vector search features against PostgreSQL/pgvector. The current test cycle models the expected behaviour of real-world customer deployments using complex queries that span multiple indices (vector and non-vector) and run in up to 1000 concurrent threads. These tests will be run against IRIS, PostgreSQL/pgvector, and ElasticSearch

Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.

We are starting to see this error message...

I am building a web application that uses JWT for authentication. I would like to pass the token in cookies instead of the Authorization header.
Is there a way to intercept the request and check the token from the cookies instead of the header? I tried overriding the OnPreDispatch() method and adding it to my dispatch class, but it seems like it never gets executed, as the response returns "Unauthorized" before reaching it.
