Hi Guys,

We currently use wkhtmltopdf to convert our html based Zen page reports to PDF using in windows, but because we are now moving to IRIS running in a container we can use that anymore and I've been told that IRIS does have some kind of tool kit or utility that can do similar job and I'm not talking about  GenerateReport() methond in zen reports?

 

Thanks

Question Jerry Petrole · Apr 9, 2025

Hello, 

One of our clients has a 'Notes' class with over 3 million records.   We have a report that pulls data from this table that was taking about an hour to run.   Our test environment (which has a copy of the production database) runs the same report query in 1 second.    

We attempted to purge and rebuild indices which made an improvement (down to 15 minutes) but still not great.

Next we ran tune table through the Mgmt Portal and it timed out.    I then ran tune table via the Terminal and it finished in a couple minutes.

Question Webby Jett · Apr 10, 2025

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?

Thanks for any help!

Question Gary M Lusso · Apr 9, 2025

I need to add an extra blank OBX segment after a segment containing text, Total Cost:

I get the OBX segment but it is in incorrect location.

It should be after the line containing Total Cost:

It needs to contain:

OBX|1|TX|2000.02^REASON FOR REQUEST^AS4|

code:

    //Do pOutput.SetValueAt(tOBXText_"~~","ORCgrp(1).OBRuniongrp.OBXgrp("_i_").OBX:5","set") //
         If (tOBXText[ "Total Cost:") {
             Set tSegmentOBX = ##class(EnsLib.HL7.Segment).%New()
             Set tSegmentOBX.SegType = "2.3:OBX"
             Set tSC = tSegmentOBX.SetValueAt("OBX", 0, "set")
             Set tSC = pOutput.

Background

Embeddings is a new IRIS feature empowering the latest capability in AI semantic search.
This presents as a new kind of column on a table that holds vector data.
The embedding column supports search for another existing column of the same table.
As records are added or updated to the table, the supported column is passed through an AI model and the semantic signature is returned.
This signature information is stored as the vector for future search comparison.
Subsequently when search runs, a comparison of the stored signatures occurs without any further AI model processing overhead.

Question Scott Roth · Apr 9, 2025

I have a segment within a Group (grp) that needs to be validated that it is populated within the message. 

When you use a Foreach within a Business Rule how should you account for the counter in the group?

For example, Epic sends their MFN message in the following format.

MSH~MFI~[~{~MFE~STF~PRA~[~ZPR~]~[~ZLK~]~[~CER~]~[~ZMG~]~[~ZTF~]~[~ZGP~]~[~ZDD~]~}~]

so, the ZLK segment might not exist until the last MFEgrp that is in the message. I need to verify if there is an Employee ID associated with the Provider in the HL7 message before I run it through the translation.

Question Fahima Ansari · Mar 21, 2025

I am receiving the garbled text due to incorrect encoding or decoding. I tried to use the $zconvert function to convert it into the normal text but failed to do that. Can anybody suggest what I have to use to convert that into normal text?

Example: Garbled text that I am getting is "canââ¬â¢t , theyââ¬â¢re".

I'm trying to validate a %Stream.GlobalCharacter with an XML content against an XSD schema, to validate mandatory nodes, etc...

I'm trying to use the Ens.Util.XML.Validator class, as suggested on this post:

However, when calling the ValidateStream method, if schemaSpec is left empty, it just validates that is a "valid

Migrating InterSystems IRIS and InterSystems IRIS for Health from on-premises to the cloud offers many advantages for Application Providers and Solution Providers. These advantages include simplified operations, access to flexible resources, and enhanced resilience. Companies no longer need to worry about the physical constraints and expenses associated with maintaining on-prem infrastructure, such as power and space requirements and expensive computer hardware.

One of the most compelling benefits is the ability to accelerate speed to market. By removing the burden of infrastructure maintenance, cloud environments enable faster development and deployment cycles, allowing businesses to respond quickly to market demands and opportunities. Operational costs are also lowered, because companies can scale resources up or down based on actual needs, leading to more efficient use of capital. Moreover, migrating to the cloud can contribute to a reduced carbon footprint by optimizing energy usage through shared cloud infrastructure.

Transitioning to the cloud may involve significant changes. Companies may benefit from a more operational focus, managing and optimizing cloud resources continuously. This shift may require changes to business models, reconsideration of margins, and strategies for scaling operations up or out. While requiring more investment, embracing these changes can lead to improved agility and competitive advantage in the marketplace.

Introduction

Database performance has become a critical success factor in a modern application environment. Therefore identifying and optimizing the most resource-intensive SQL queries is essential for guaranteeing a smooth user experience and maintaining application stability. 

This article will explore a quick approach to analyzing SQL query execution statistics on an InterSystems IRIS instance to identify areas for optimization within a macro-application.

Rather than focusing on real-time monitoring, we will set up a system that collects and analyzes statistics pre-calculated by IRIS once an hour.  This approach, while not enabling instantaneous monitoring, offers an excellent compromise between the wealth of data available and the simplicity of implementation. 

We will use Grafana for data visualization and analysis, InfluxDB for time series storage, and Telegraf for metrics collection.  These tools, recognized for their power and flexibility, will allow us to obtain a clear and exploitable view.

More specifically, we will detail the configuration of Telegraf to retrieve statistics. We will also set up the integration with InfluxDB for data storage and analysis, and create customized dashboards in Grafana. This will help us quickly identify queries requiring special attention.

To facilitate the orchestration and deployment of these various components, we will employ Docker.

Question Timothy Leavitt · Mar 31, 2025

I'm exploring this right now: given a bunch of types defined as Pydantic models, how can I come up with an equivalent %RegisteredObject/%SerialObject and convert to/from (e.g., to support persistence and match validation as much as possible)?

People who know Python better than I do (e.g., your average undergraduate from this decade): is this a stupid idea or a cool idea? Has anyone else done this before?

Question Touggourt · Apr 6, 2025

Hi,

 

How can I query fields by passing them in variable names, eg. I would like to query columns Book & Author fields from eg. the following :

S =var1="Book", var2="Author"

Select  var1,var2 from myTables.Books

I tried @var1 or %var1 and didn't work

 

Thanks

Hi 

Is there a way to remote connect to IRIS terminal from my local machine?

I can remote connect to Studio & SMP from my locally windows installed IRIS cube to another IRIS installation in a Linux server, but not the case when trying to connect to the Terminal, is there a way to do so? I'm currently using ssh client but that one times out quickly     

 

Thanks

Hi Community,
Traditional keyword-based search struggles with nuanced, domain-specific queries. Vector search, however, leverages semantic understanding, enabling AI agents to retrieve and generate responses based on context—not just keywords.
This article provides a step-by-step guide to creating an Agentic AI RAG (Retrieval-Augmented Generation) application.

Implementation Steps:

  1. Create Agent Tools
    • Add Ingest functionality: Automatically ingests and index documents (e.g., InterSystems IRIS 2025.1 Release Notes).
    • Implement Vector Search Functionality
  2. Create Vector Search Agent
  3. Handoff to Triage (Main Agent)
  4. Run The Agent
