Question Anderson Negreli · 2 hr ago

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.

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.

Question Norman W. Freeman · Feb 25

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

Question Scott Roth · Mar 2

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.

Question Malaya Acharya · Mar 1

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.

Question Arsh Hasan · 20 hr ago

So I have an SSIS package that I want to call from a business operation.

For that I am using SQL Outbound operation. However, on trying with ExecuteQuery and ExecuteProcedure Functions, I only see an exeuction ID being generated, but the execution never starts. 

I tried two methods:

Executing the SSIS package directly from Execute Query function, but again just execution ID was generated. I could not see the execution in the SSISDB logs.

Executing the SSIS package via a Stored procedure and having ExecuteProcedure trigger the procedure, but same problem.

in C++ program with #include iris-callin.h..  The program terminateswhen it tries to execute IRISSECURESTARTA with exit code -1073741515.

const char *username="user", *password="xyz",*exename="Test_Callin";
int termflag = IRIS_PROGMODE|IRIS_TTNONE|IRIS_TTNEVER;

rc = IRISSECURESTARTA(&pusername, &ppassword, &pexename, termflag, timeout, NULL, NULL);

Note: the %Service_Callin setting is Enabled.

Question Malaya Acharya · Mar 2

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.

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.

Question Scott Roth · Feb 27

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.

Picture a dark room. The only light comes from a wall of displays and a blinking prompt that politely informs you:

“LINK TO M-U5K-3T: HIGH LATENCY – DIRECT CONTROL DISABLED.”

Perfect.

You are supposed to be a Rover Commander in the Musketeer Corps. Somewhere absurdly far away, you have an autonomous unit parked on a hostile exoplanet. It wants you dead, but it’s also covered in minerals that could fund a small civilization.

The ore on M-U5K-3T is everywhere. Unfortunately, everything else on the surface is actively trying to kill you.

So, we don't pilot. We script.

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.

Discussion André Sheydin · Feb 28

Hello everyone,

I am André from MedVertical. We are exploring InterSystems-native ways to operationalize continuous FHIR conformance: repeatable regression runs, baseline/delta comparisons, and evidence-style reporting to detect drift after releases and IG changes.

In many FHIR implementations, validation is done “point-in-time” in pre-prod, but conformance degrades in production due to IG/profile updates, terminology changes, mapping evolution, upstream releases, and configuration drift.

Question Yone Moreno Jiménez · Feb 24

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.

If one of your packages on OEX receives a review, you get notified by OEX only of YOUR own package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you made a major change and expect a changed review, just let me know.
