Hi Community,

Are you already InterSystems certified, or thinking about taking that next step?

Hi

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 #613

I have a large tree outside my window. Here in Phoenix, Arizona, USA it's still warm and sunny so our plants are still covered in lush foliage despite so many other places in the full throws of Autumn. My desk is oriented such that I can look out at the tree throughout the day. Part of the reason I like having my desk facing the tree is because I need the break from staring at the computer screens but the other reason is because I need reminders from nature from time to time.
Today I'm reminded of two things:

1. Growth requires absorbing from your environment
2. Growth doesn't always happen in the

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.

Professional Grade FHIR® to OMOP Transformation

Lets zero in on the use of the word professional and put it into some context.  It was written by industry experts who wrapped it up in a fee based service with support and some guardrails around flexible options to contribute to its behavior.  I feel its an important distinction to either an open or home grown solution (though it may do the same thing) to consider it to scale or provide mission critical value on the other side of it. The OHDSI community has an entire competency around the subject of ETL to the OMOP database,  WhiteRabbit for

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.

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!

Mirroring only synchronizes database files.

To synchronize other files required for your application (CSP files, images, documents, etc.) between the two servers that make up the mirror set follow one of the approaches:

1. Place those files on a shared disk by introducing a NAS or similar device
2. Or use file sync software to synchronize files between two servers.

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 SQL

..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: Table -

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
}

New to HealthShare, I wanted to know if there was a way to modify the locations-card within the Provider Directory? I am not seeing a reference to where the Cards are stored within the documentation.

This might be a dumb question but can we have more than one production in a namespace, because we do have running but I thought that I could create a separate one for another project?

Thx   

Hi Guys,

I'm a newbie in Python and I've imported this class from another IRIS and for some reason its get an error on %ToJSON()?

I'm also wondering on the need of importing iris at the top given that this code is already running in IRIS!? 

Thanks

Hi Guys,

I get the below error when trying to compile an imported class in IRIS, it compiles if I remove [ Collection = list ] so not sure about the use of  [ Collection = list ] and if removing it would affect anything and its just a duplication?

Thanks

Getting this error when create a class in IRIS, any clues?

Thanks

⏯️ Health Evolve: Transforming Unstructured Data

Did you know that 80% of healthcare data is stuck in unstructured formats such as fax? If you take a walk down to Mass General in Boston, you'll literally see a state-of-the-art MRI machine next to a fax machine. Healthcare keeps building incredible new technology but can't let go of legacy technology. We call this the "legacy modernization paradox". This short film follows a care manager at Blue Plan who spends her days doing chart reviews, reading faxes line-by-line, struggling to provide her members the care they need. Everything changes when Blue Plan pilots InterSystems Health Evolve, a solution that transforms her faxes into machine-readable FHIR data ready for AI and analysis.
