My query that I am running on my Custom SQL Inbound Service has columns that are larger than the typical string length. How do I enlarge the SQL Snapshot Column limitations

Hi guys,

I am looking for a way to search for FHIR Encounter resources from an InterSystems FHIR server where there period.start is before or after a certain time. I can´t get my head around which would be a correct way to do this since docs and FHIR spec is not clear to me which fields can be used for searching with wich prefixes.

In my local InterSystems FHIR server I have a set of Encounter ressources, each set with a period.start and (possibly) a period.end. I´d like to retrieve all Encounters with a start date time prior to a given datetime. I did a little testing with URL parameters.

I want to append items to the list inside a for loop

Example:

set mylist = $ListBuild()
for i = 1:1:5 {
    set item = "item"_i
    set mylist = $ListBuild(mylist,item)
}

zw mylist

The output should be:

mylist = $lb("item1", "item2", "item3", "itme4", "item5")

The code snippet written above is not working, looking for correct way to do it.

Is there a way to delete suspended messages rather than using the WebMgmt gui?  

We have over three million in one namespace, and using the gui I can only do 2000 at a time. 

I was thinking of using delete in sql like  Ens.MessageHeader where Status = 'Suspended'

But I don't know if that is a clean way to do it.

Hi Community,

There is a new PDF Resource published on our official site depicting key features and a comparison of InterSystems healthcare interoperability products: Health Connect and IRIS For Health.

I think this could be useful for the Community.

Hello,

i am building a new container with Docker-Compose with a --volume ./:/irisdev/app:rw to mount a host volume (UBUNTU).

If i try to create some data in /irisdev/app i have no write permission

If i open a bash host session i see all mounted files of my ./ directory. But with ls -l only UID 100 has write permission. The UID for "iris owner" is 52773.

Is there a way to set the UID and Group to "iris owner" ?

regards Matthias

We think you might have a few suggestions on how we can improve our search engine, and we would absolutely love to hear from you!

Hello everyone,

I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.

If there's a resource that also includes step-by-step instructions and perhaps even offers a certification upon completion, that would be perfect.

Any recommendations or guidance would be greatly appreciated. Thanks in advance! 😊

Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)

I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date

Select Sum(MsgCount)

From

(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount

FROM ENS.

Hi colleagues!

Often, while developing a frontend app or any other communication vs REST API, it is worth having a Swagger UI - a test UI for the REST API that follows Open API 2.0 spec. Usually, it is quite a handful as it lets have quick manual tests vs REST API and its responses and the data inside.

Recently I've introduced the Swagger support to the InterSystems IRIS FHIR template for FHIR R4 API:

How to get it working.

Intro

In the process of trying to get more familiar with Objectscript I decided to try to build a general priority queue since I wasn't able to find an implementation anywhere. My though process for implementing this followed this general path.

Binary Heap

My first though to try to make this work quickly was to implement a binary heap and my first attempt at this used a multidimensional to build it. This version was relatively efficient, worked for strings/numbers natively, and worked for objects be letting the user override the comparitor.

Class pqueue.

If there is a way we can find how much a particular namespace is utilizing the O/S CPU and memory, that will be great in resource utilixation as well as capacity planning.

In this article I'll show you how to set up in your laptop, very quickly, a cluster of IRIS nodes in sharding. It's not the goal of this article neither to talk about sharding in detail nor define a deployment of a production ready architecture, but to show how to set up quickly, in your own machine, a cluster of IRIS instances configured as shard nodes, with which you'll able to play and test this functionality. If you're insterested in knowing more about sharding in IRIS, take a look at the documentation clicking here.  

First and foremost, I want to remark that IRIS sharding will allow us 2 things:

• Define, load and query shard tables, which data will be distributed transparently between the cluster's nodes
• Define  federated tables, which offer a global and composed view of data belonging to different tables that will be physically stored in different distributed nodes

So, as I said, we let for other article playing with shard or federated tables, and just focus now in the previous step, that is, setting up the cluster of shard nodes.

Hi all,

I'm working on a requirement to loop through all encounter streamlets(SDA) to identify specific encounters based on an encounter extension property for a patient fetch request. However, this current process is time-consuming, and we need to create indexes for that property to quickly retrieve the expected results without going through all the encounter streamlets of a patient.

I would appreciate help on how to achieve this, as I couldn't find any documentation explaining how to create indexes on a SDA element.

Thanks in advance.

We recently changed the 'UserID" property in a "User" class from type of %String to be %Library.Username. This is for better consistency across our codebase regarding MAXLEN limit.

%Library.Username is a system wrapper datatype which extends %String and has a MAXLEN of 160. This change should have minimal/no impact on code behavior. However, we found that some SQL query cannot return expected rows after the change. Query will return empty values even if the entry is in the table.

Using IRIS 2024.1.2 when I mount the routine database as read-only I get an error when executing dynamic SQL queries.

What globals need to be mapped in a read-write database in order to allow execution plans to be written?

Hey,

I need to read a directory on a remote server which requires a user to be su. The question is how to correctly read the server response and then to send a su password using IRIS device I/O API (I'm able to read other commands output such as uname, but can't figure out how to switch to su):

// Init SSH session
Set .Session = ##class(%Net.SSH.Session).%New()
Set status = .Session.Connect(.Server)
$$$ThrowOnError(status)
Set status = .Session.AuthenticateWithUsername(.UserName, .Password)
$$$ThrowOnError(status)

// SUDO
#Dim device
Set device = ""
Set status = .

Hi,

I would like to convert an html zen page to PDF using wkhtmltopdf so I've installed it in Ubuntu and the command wkhtmltopdf but because I've my IRIS installed in a container that command is not recognized and we can't install wkhtmltopdf  in the container so is there a way to be able to run this command?  

Thanks

Mitigating climate change is only possible through a patchwork of collective action. The future of our planet will be determined by our ability to change previous destructive corporate processes radically. However, companies often struggle to find concrete solutions and actions to reduce their carbon footprint while advancing their business goals.

We partner with Race to Zero to create a climate action matcher.

Introduction

As the health interoperability landscape expands to include data exchange across on-premise as well as hosted solutions, we are seeing an increased need to integrate with services such as cloud storage. One of the most prolifically used and well supported tools is the NoSQL database DynamoDB (Dynamo), provided by Amazon Web Services (AWS).

The challenge for IRIS implementations, as it relates to Dynamo and other modern web services, is that there is no native support for interacting with Dynamo and AWS within ObjectScript.

Hello, dear colleagues.

I need to connect to a remote JavaGateway from an Ensemble service.

I am trying to use the EnsLib.JavaGateway.Service with a remote host where the JVM is running.

I can successfully ping the remote Java Gateway from EnsLib.JavaGateway.Service, and Ensemble reports that the service status is OK.

There are no network issues, and all necessary ports are accessible.

My requests work without any problems when I specify localhost in EnsLib.JavaGateway.Service.
