Hello Everyone,
I’m excited to join the InterSystems Developer Community, a place where IRIS, Caché, Ensemble, HealthShare, and all things InterSystems come alive through shared knowledge and collaboration.

A little about me,

• I’m passionate about building efficient, integration-driven solutions, exploring ObjectScript, working with REST APIs, and diving into analytics tools like DeepSee and IntegratedML.
• I’m here to learn from your real-world experiences, whether it’s tips on interoperability, performance tuning, or best practices across IRIS and HealthShare ecosystems.
• I also look forwar

Is there a better way (i.e., without string commands) to remove the fractions of seconds from a %Library.PosixTime value?

This works, but seems inefficient:

set posix = 1154669852181849976w##class(%Library.PosixTime).LogicalToTimeStamp(posix)
2025-05-2712:06:15.003set str = ##class(%Library.PosixTime).LogicalToTimeStamp(posix)
set stripped = $P(str,".",1)
w##class(%Library.PosixTime).TimeStampToLogical(stripped)
1154669852181846976set newposix = ##class(%Library.PosixTime).TimeStampToLogical(stripped)

I have a vendor that only wants results on patients that arrive to the ED via EMS/Ambulance.  The value I need for filtering is in the PV2;38. Some of the results requested do not allow the PV2 segment to be added to the schema in the EMR.  I was told that other orgs have used a lookup table that is populated with the PV1;19 value when an ADT messages that meets the criteria is sent in.  This table is then referenced in the business rule for the results that do not have PV2;38 and if Encounter number from result message exists on the Table, the result is sent.  Has anyone done this before?  

There is a way to remove the web source control in the web page of BPL?

i already disabled a configuration in the production and works fine:

But in the BPL page, it doesn't worked. There is a way to disable this configuration at portal?

#InterSystems Demo Games entry

This demo introduces an AI-powered clinical decision support tool built on InterSystems IRIS. The use case addresses clinician burnout by unlocking the wisdom trapped in 30,000 unstructured clinical notes. We showcase IRIS's powerful vector search to perform hybrid (semantic + keyword) queries for complex diagnostic challenges. The highlight is our multi-modal Retrieval-Augmented Generation (RAG) assistant, which analyzes clinical video content in real-time to find similar past cases and synthesize evidence-based recommendations, transforming how clinicians access and utilize institutional knowledge.

We currently have Business Operation that we built to use the EnsLib.SQL.OutboundAdapter so we can make Microsoft SQL Server Stored Procedure calls. The BO is attached to a Java Gateway Service.

Some of our MS SQL Databases have moved from being OnPrem to Azure Cloud. We have started seeing where we are receiving errors on the BO saying that we cannot connect to the Azure Database, but we never receive a Disconnect from the Azure Database.

Once this happens it seems that the Java Gateway still thinks the connection is opened, and we have to Stop/Start the Java Gateway to get the connection t

Hi Everyone,

So after @Ariel Glikman posted a custom operation example, I'm stuck on another dilemma, and here it is:

1. I might have different patients with the same business identifier
2. Each patient (logical) might have several resources like Observations, Conditions and Tasks (there are other type but they are not part of the issue)
3. Tasks are a representation of something called "Morbidity", it's a presumed illness but not a validated condition
   1. Tasks are created according to observations and/or conditions and the task hold a reference to those resources
   2. A resource such as Observation

Hello community.

I have a request from a client who wants to do the following.
Currently, they have a data upload process via FTP in which they have implemented a RecordMap to store the information of the CSV files that are uploaded to the FTP directory.
Now they want to have another directory so that it is ONLY executed through an external instruction, not when the file is uploaded to the directory.

Is it possible to create a process that reads the FTP directory on demand? That is, ONLY executes the EnsLib.FTP.InboundAdapter service when we tell it to.
There would be no problem creating an API

Hi

I'm a newbie in productions and I've received the below business operation from a client that I need to include in a production,

So not sure if I'm supposed to create a new Business operation with a new name and select the class as below but then what's next and what should be the output type in X12 tab or if it should be type SCOSwarm.Message.SX3ScheduleResponse?

Or should I be ignoring this class for now, create a new business operation called SCOSwarm.Operation.SX3ScheduleOp copy the code across ...etc but how can I include EnsLib.NullAdapter ?  

Thanks

Hi Community,

We’ve got something exciting for you — it’s time for a new demo video contest, and this time, you’re in the judge’s seat!

📺 Demo Games for InterSystems Sales Engineers 📺

For this contest, InterSystems Sales Engineers from around the world submitted short demo videos showcasing unique use cases, smart solutions, and powerful capabilities of InterSystems technologies.

Now it’s your turn! We’re opening up voting to the entire Developer Community. Your insight and perspective as developers make you the perfect experts.

Given the code below, I need help with getting the collected column widths from the Demo.Configuration table and stored in the columnWidths zne page property. As I understand it, I should be able to retrieve it using zenPage.columnWidths in the setColumnWidths or dgRender clientMethods but the alert is showing that it cannot be retrieved as it shows a value of Null. Once I can retrieve those values, then I want to set the widths of the colmns of the dynaGrid according to the values in the ^Demo.Configuration table. The data pulled in from the CSV file that creates ^Demo.Import can have a diffe

Hey folks! Having recently onboarded to InterSystems, I realized that despite having a totally free and awesome Community Edition, it's not super clear how to get it. I decided to write up a guide highlighting all the different ways you can access the Community Edition of InterSystems IRIS:

Get InterSystems IRIS Community Edition as a Container

Working with a containerized instance of the Community Edition is the recommended approach for folks who are new to developing on InterSystems IRIS, and in my opinion it's the most straightforward. InterSystems IRIS Community Edition can be found on DockerHub; if you have an InterSystems SSO account, you can also find it in the InterSystems Container Registry.

In either case, you'll want to pull the image you want using the docker CLI:

docker pull intersystems/iris-community:latest-em
// or
docker pull containers.intersystems.com/intersystems/iris-community:latest-em

Next, you'll need to start the container: In order to interact with IRIS from outside the container (for example, to use the management portal) you'll need to publish some ports. The following command will run the IRIS Community Edition container with the superserver and web server ports published; note that you can't have anything else running that depends on ports 1972 or 52773!

docker run --name iris -d --publish 1972:1972 --publish 52773:52773 intersystems/iris-community:latest-em

FHIR Server

A FHIR Server is a software application that implements the FHIR (Fast Healthcare Interoperability Resources) standard, enabling healthcare systems to store, access, exchange, and manage healthcare data in a standardized manner.

Intersystems IRIS can store and retrieve the following FHIR resources:

• Resource Repository – IRIS Native FHIR server can effortlessly store the FHIR bundles/resources directly in the FHIR repository.
• FHIR Facade - the FHIR facade layer is a software architecture pattern used to expose a FHIR-compliant API on top of an existing one (often non-FHIR). It also streamlines the healthcare data system, including an electronic health record (EHR), legacy database, or HL7 v2 message store, without requiring the migration of all data into a FHIR-native system.

What is FHIR?

Fast Healthcare Interoperability Resources (FHIR) is a standardized framework created by HL7 International to facilitate the exchange of healthcare data in a flexible, developer-friendly, and modern way. It leverages contemporary web technologies to ensure seamless integration and communication across various healthcare systems.

I'm trying to assess whether git-source-control will work for our development environment.  I've watched some videos and read the documentation and read some posts and I'm still unsure whether it works with multiple developers using a shared remote development environment (i.e. namespace).  This [Video] Let InterSystems IRIS Do the Work: Git Source Control & Linting says that you can have multiple developers and says it's "Package Manager-aware (supporting multiple repos in one namespace)" whereas  this post on the git-source-control github Remote development and multiple users · Issue #61

Hey Community,

It's time for the new batch of #KeyQuestions from the previous month.

Often times when working with FHIR data, for example with IRIS For Health, you'll find it useful to create a custom FHIR operation. The FHIR Standard comes with a set of defined operations (such as $everything) but a custom operation comes in handy when you need to create some extra functionality that goes beyond the set of standard FHIR operations. The docs take you step-by-step (though this comment may be helpful to those of you just getting started). One thing I would highlight, purely for aesthetic purposes, is how to syntactically name your function such that you can call it with hyphens.

We have a task that runs objectscript code to load data into a linked external table.  After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message.  The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is.  The result is the same with and without the USING clause, so don't let that confuse you.  We have logs of this statement succeeding before upgrade, and were able to get this statement to work in our production environment, which is still on version 2024

Welcome to the 2025 third quarter update.

Last quarter, we had a few important announcements that are worth reiterating this quarter.

• RHEL 10 support was added to IRIS 2025.1
• 2025.3 will use OpenSSL 3 across all operating systems  SUSE 15 sp6 will be the minimum OS for orgs using SUSE
• The minimum CPU standards are going up in 2025.3
• Older Windows Server operating systems will no longer be supported in 2025.3

If you’re new to these updates, welcome!  This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tric

Hello,

I am currently maintaining a legacy application that was developed in ObjectScript and accesses data by working directly with globals.
For a new program, however, I plan to access the same global data through SQL-mapped classes.

I have two questions regarding this approach:

1. If I define indexes in the SQL-mapped class, what potential impact (if any) could this have on the existing legacy application that directly accesses the globals?
2. I’ve read that when an index is defined in an SQL class, it will not be automatically updated if data is modified directly in the global (outside of

..Contains(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"(")&&..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")

I want to do this to match strings such as X98. Community AI tells me this is correct but I get an error in testing. Specifically, this is the part causing the error;
..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")

What do I need to change?

Dear, Community!

I have a concern about using %Stream.TmpCharacter for storage purposes. Reading the class's source code, I can understand a bit about how it works. But I'd like to know from the community how it actually works. Is it necessary to use the .Clear() method to clear this buffer, or is it done automatically upon disposal?

Note: Please forgive my poor English.

InterSystems FAQ rubric

In InterSystems IRIS, you can create linked tables using commands, instead of using System Explorer > SQL > Wizard > Linked Tables in the Management Portal:

To create a linked table, use the CreateLinkedTable method of the %SYSTEM.SQL.Schema class. See the class reference for details.

To execute it, follow these steps:

set sc = $SYSTEM.SQL.Schema.CreateLinkedTable("<dsn>","<Schema>","<Table>","<primaryKeys>","<localClass>","<localTable>","")

/// 1st argument: dsn - SQL Gateway connection name/// 2nd argument: Schema - Source schema name/// 3rd argument: Tab

Hi Everyone, I'm Prakash Hinduja, a financial advisor and consultant. My roots in India now living in Geneva, Switzerland (Swiss). I'm looking for some suggestions on how to get the best performance from Adaptive Analytics 2023.2. I know it uses Adaptive Parallel Execution and automatic aggregates, but I'm curious if you've found any other tips or tricks. For example, are there any specific data modeling choices or system configurations that have worked well for you? I'm trying to make our cubes as responsive as possible. Thanks in advance for any insights!

Hi folks!

Sometimes, when designing a class method and feeding it with more and more useful features, very soon the number of parameters can reach 10 and even more.

It becomes pretty difficult for users of useful methods to remember the position of the important parameter, and it is very easy to misuse the position and transfer the wrong value to the wrong parameter.

Here is an example of such a method (I asked GPT to create a method with 20 params):

ClassMethod GenerateReportWith20Params(
    pTitle As%String = "",
    pAuthor As%String = "",
    pDate As%String = "",            // e.g. 2025-09-03
    pCompany As%String = "",
    pDepartment As%String = "",
    pVersion As%String = "1.0",
    pFormat As%String = "pdf",       // pdf|html|docx
    pIncludeCharts As%Boolean = 1,
    pIncludeSummary As%Boolean = 1,
    pIncludeAppendix As%Boolean = 0,
    pConfidentiality As%String = "Public",
    pLanguage As%String = "en",
    pReviewers As%String = "",       // CSV, e.g. "Alice,Bob"
    pApprover As%String = "",
    pLogoPath As%String = "",
    pWatermarkText As%String = "",
    pColorScheme As%String = "default",
    pPageSize As%String = "A4",
    pOrientation As%String = "Portrait",
    pOutputPath As%String = "report.pdf"
) As%Status
{

// implementation
}
