We have an HL7 feed that contains Lab Results. Each message contains a set of results, identified by a LabReportId. Some LabReportIds can get more than one message / set of results - these are updates, as new results become available, and must be processed in order. Results for different LabReportIds can be processed in any order.

As each message is used to build a PDF, which takes time, we want to run these through a production where the key business process has a Pool Size > 1, while still ensuring that messages for each LabReportId are processed in order.

I had configured the environment as follows:

OS: Redhat Linux 9.4

IRIS 2025.2 installed on local directory

IRIS Database: One LVM is created with 20 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that

Primary and Alternate Journal: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

WIJ: One LVM is created with 5 Storage luns and the LVM is mounted on a mount point. IRIS database is created on that.

So Data, WIJ and Journal is mounted on 3 separate mount point.

Anyone up for a round of golf?

Are you fed up of making a machine write code for you? Do you miss thinking through problems yourself? Then you are in luck, this round, I propose adding the rule of no AI use. obviously its a game of honor with no prize, so I shan't be enforcing this, but you'll know... 

Challenge:

Create a function which takes a string as a parameter, and returns the length of thelongest sequence of alternating consonants and vowels. The sequence is broken by having two vowels or two consonants in a

I am currently managing environments running InterSystems IRIS and Caché on Windows servers.

I’m reviewing storage optimization best practices and I have a question regarding a specific Windows drive setting: "Allow files on this drive to have contents indexed in addition to file properties."

Based on my research, everything indicates that it is better to disable this option, especially on drives used by databases. However, I couldn't find a specific "official" stance in the documentation explicitly mentioning this checkbox.

Why This Integration Matters

InterSystems continues to push AI capabilities forward natively in IRIS — vector search, MCP support, and Agentic AI capabilities. That roadmap is important, and there is no intention of stepping back from it.

But the AI landscape is also evolving in a way that makes ecosystem integration increasingly essential. Tools like Dify — an open-source, production-grade LLM orchestration platform — have become a serious part of enterprise AI stacks.

I have installed IRIS community edition on a local directory in Redhat Linux 9.4.

Created a 10G database on a separate mount point directory  which comes out of a storage volume of 50G.

Also placed Journal and WIJ on 2 separate mount point directories  which comes out of two different storage volume of 50G each.

I want to take a snapshot and recover the snapshot on a secondary host and check the consistency of the database. 

As Storage snapshot will be taken, only Data, Journal and WIJ file placed on Storage volumes will be snapshotted.

Is there any Cache setting that needs to be checked while configuring IRIS Community Edition 2025.2 and does it impact WIJ recovery.

Also I have kept Database, WIJ and JOURNAL on the same snapshot group with Consistency . Is it the recommended settings? Am I getting the WIJ mismatch error due to this setting?

Configuration differences between environments are not always mistakes, but they should always be intentional and governed. 

We're excited to announce that version 3.6 of JediSoft IRISsync® is now available, bringing enhancements designed to give teams more control and visibility when managing configuration settings across multiple IRIS instances.

What's new in IRISsync 3.6: 

• Accepted differences - Mark intentional configuration differences to provide further clarity in comparison results.

I have a global with multiple nodes : 

^A("ABC") = ""
^A("DEF") = ""
^A(123) = ""

How to create a new single node in that global, in a way it's always at the end of the global (eg: this will be the very last node being enumerated)

I end up with this code but maybe there is a cleaner and simpler approach : 

set ^A($char(65535)) = "" //should be bigger than any character inserted
set ^A($char(255)) = ""   //some systems does not seems to support >255 characters, this might be safer

I only need to write it once, this code is not intended to be used in a loop or something, just to add something at

Hi 

Is there a sample that I can use to create a simple alert code, and do I need to set up or pay a service provider? 

Thanks

I am stuck at a crossroad and was wondering if I could get a second pair of eyes to help with a query that I am sending from a Task to a Service to process some data.

I have a Linked Table (view) that points back to a MS SQL View that I am trying to query. However, my execution keeps either failing or not returning any rows. When I take the SQL Query and execute it within the Management Portal I get results, however Cache is not seeing it when trying to execute this code.

Role Summary

We are building a federated healthcare data platform enabling secure, privacy-preserving research across hospitals and medical devices in multiple regions.

We are seeking a Team Lead for Development who will own the technical delivery and execution of this platform — translating architectural direction into implemented systems and coordinating multidisciplinary engineering teams.

This role sits between architecture design and operational deployment.

I am trying to create a task that has a variable property that a user can specify DaysBack but it keeps coming up blank when I ask the system to get the date as of DaysBack from the CURRENT_DATE. Can someone tell me why I am not getting a value back in my tDate variable?

Class OSU.Workday.TerminationsTask Extends %SYS.Task.Definition
{

Parameter TaskName As STRING = "OSU - Workday Termination Update";

Property DaysBack As %Integer [ InitialExpression = 1 ];

Method OnTask() As %Status
{
	Set tSC=$$$OK
	#Dim tException as %Exception.

Global Guard AI

1 Introduction

In environments that use InterSystems IRIS, globals are the physical foundation of data storage. Although system queries and administrative tools exist for metric inspection, global growth analysis is usually reactive: the problem is generally only noticed when there is disk pressure or performance impact.

The facial recognition has become the most popular method for validating people's identities, thus enabling access to systems, confirmation of personal and documentary data, and approval of actions and documents.
The challenges are related to performance when the database is very large, accuracy, and especially the privacy of biometric facial data. For these challenges, nothing is better than using InterSystems Vector Search, as it allows:

1. Performing vector searches in millions of records with much faster responses than traditional methods.

Hello, how are you?

Using Healthshare for Interoperability, we often see a wide variety of encoding issues. Some happen when transforming XML to HL7. Some happen the other ay around transforming HL7 to XML.

Is there a valid way to understand which encoding needs to be used?

I ask, because we use SOAP or REST or TCP HL7 services.

And we deliver messages with TCP HL7, SOAP, HTTP Operations.

And we often face this issue where special characters like ñ or á, are not encoded correctly.

Thanks for your replies.

Hello!

I am requesting feedback on the usage and experience of the Schema Viewer feature available in Interoperability-enabled products (IRIS, IRIS for Health, Health Connect). This feature is accessible via Interoperability > Interoperate. 

Some questions to jog your discussion/comments below:

1. What's one enhancement that would drastically change your experience or enable faster schema configurations?
2. If you are not a user of this feature (but need to create custom schemas/view your schemas), why do you not use the schema viewer?
