I am currently monitoring our license use with a new rest-service I am implementing when I noticed my licenses on my instance being consumed and never released by Visual Studio Code.

For this I restarted my Instance, watched the licenses for a while, which remained at 1 during idle (I am guessing my MMGT Portal session uses 1) 
But when I connect to my Instance using Visual Studio Code (with my Instance setup in the extension already), suddenly 2 licenses are used.

Hello IRIS community,  

InterSystems Certification is developing a certification exam for InterSystems IRIS Developer professionals, and if you match the exam candidate description given below, we would like you to beta test the exam.

Hi Guys,

How can I use this same objectscript principle in embedded python to get the value of each field in my loop? 

  s sql="SELECT ID, Name, Age FROM Sample.Person WHERE Age="_Myage    

     Set RS=##class(%ResultSet).%New()

    Set Ret=RS.Prepare(sql)

    Set Ret=RS.Execute()

    While RS.Next()

    {

         Set name=RS.GetData(2)

}

it should be similar to this example which lists the whole row but how can I get the value of each field or if I can use GetData?  

Thanks

I ran into a situation where VS Code consumed all available web sessions and was unable to get to the Management Console to clear them. I was able to establish a terminal session, though.

Is there a method or routine available through the IRIS terminal that allows one to clear web sessions? I've searched the administration and class documentation and haven't found a solution.

I installed a local docker container instance from here:   intersystemsdc/iris-community

I'm trying to login:    http://localhost:52773/csp/sys/UtilHome.csp

I thought if I used SYSTEM as the initial username, I could login, but I get #822 Access Denied.

Is that the correct username? maybe there's a better location to pull the docker instance.

Migrating from Oracle, MSSQL, or other purely relational database systems to a multimodel InterSystems IRIS is a strategic decision that requires careful planning and execution. While this transition offers significant benefits, including enhanced performance, scalability, and support for modern architectures, it also comes with challenges. In this article I will highlight some of the considerations connected to coding to ensure a successful migration. I will leave everything connected to an actual migration of structures and data outside the scope of this article.

First, when you're considering migrating to a different database system, you need to understand your business logic, whether it's on the side of the application (application server) or the database server. Basically, where do you have your SQL statements that you will need to potentially rewrite? 

I recently had to refresh my knowledge of the HealthShare EMPI module and since I've been tinkering with IRIS's vector storage and search functionalities for a while I just had to add 1 + 1.

For those of you who are not familiar with EMPI functionality here's a little introduction:

Enterprise Master Patient Index

In general, all EMPIs work in a very similar way, ingesting information, normalizing it and comparing it with the data already present in their system.

Hi devs!

What is the best way to return JSON in IRIS for a GET request in a REST app?

This is how I do it now:

ClassMethod GetAllPersons() As %Stream.Object
{
    d ..%SetContentType("application/json")
    Set rset = ##class(dc.Sample.Person).ExtentFunc()

    set stream=##class(%Stream.TmpCharacter).%New()
    d stream.Write("[")
    if rset.%Next() {
        Set person = ##class(dc.Sample.Person).%OpenId(rset.ID)
        Do person.%JSONExportToStream(.stream)
    }
    While rset.%Next() {
        d stream.Write(",")
        Set person = ##class(dc.Sample.Person).%OpenId(rset

I have an IRIS persistent class with a %Stream property whose value is a JSON object. I'd like to use a SQL trigger to pull some value out of the JSON and persist it in another property, for easy querying and indexing. See below for a minimal example:

Class PAB.DebugStream Extends %Persistent
{

Property Contents As %Stream.GlobalCharacter;
Property msg As %String;
ClassMethod InsertRow()
{
    set stream = ##class(%Stream.GlobalCharacter).%New()
    $$$ThrowOnError(stream.Write({"msg":"hello world!"}))
    &sql(insert into PAB.

Hi Guys,

I'm getting the below error when trying to train my Model

This is the table I created my model from

Thanks

I am struggling with returning a SQL Query Result that may have multiple rows that can be searched.

 set query = "SELECT Facility FROM FROM osuwmc_EnterpriseDirDB.RelationshipMedCtrID WHERE OSUmedcenterID = ?"
 SET rset = ##class(%SQL.Statement).%New()
 SET qStatus = rset.%Prepare(query)
 SET rset = rset.%Execute($Get(ID))
 do rset.%Display()

I need to take the values that are returned and say search them for a single value. How would I go about returning the EnsLib.SQL.Snapshot into a Array or List for it to be searchable.

I have a general question about HealthShare Provider Directory using Code Tables on disk vs Cache SQL Tables. Why is Provider Directory not using the Cache SQL Tables within the IRIS platform?

Hi developers!

This will be a very short article as in April 2025 with Lovable and other Prompt-to-UI tools it becomes possible to build the frontend with prompting. Even to the folks like me who is not familiar with modern UI techics at all.

Well, I know at least the words javascript, typescript and ReactJS, so in this very short article we will be building the ReactJS UI to InterSystems FHIR server with Lovable.ai.

Hi developers!

While developing web apps the security practice I consider safe and convenient is to create a special Role (e.g. equal application name) which contains security resources which application will need (SQL tables, priviledges, database access, etc) and assign it to the Web Application.
So the user gets this role once it loggs in to the application (via password, no password or delegated).

Convenient, right?

So, the question is, when I deploy the app as an IPM module what should I put as a database access?

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:

Hi,

We're having an issue with some messages being sent to a downstream system from Healthshare.  Part of the free text in the NTE segment is displaying with special characters on the system front-end but is not present in the HL7 message that we send to them.  We are guessing that this is a result of some of the text being copied and pasted from something like MS Word. The '?' on their system is just representing an invalid character. 

Is anyone aware of a way to prevent this occurring? We are sending the messages using the 'cp1252' encoding.

Has anybody tried to extend the Menu on Management Portal? I like to add a new page or a dashboard that will be created soon to the Management Portal and allow others to use it also. I understand there are risks that I could lose things during an upgrade. I am okay with that. Does InterSystems support such an effort?

What is the best way to develop Angular applications while working with CCR?

CCR peer reviewers require submitting Angular source files, so that a peer reviewer has something readable to review. However, CCR environments require that you deploy compiled Angular applications to them.

I think I found my solution but I'm trying to understand better why it works. Forgive me as my descriptions here may be scattered but I'm trying to piece the puzzle together.

Scenario: I've found there are times when I make a request using a %Net.HttpRequest object and as I'm debugging and stepping through via the debugger in VSCode, if I try to access an object in the 'variables' menu, sometimes when I click that little expand button it will just spin and never load what's in the object to the viewer.

I recently helped a site investigate a problem that appeared after they upgraded their Windows instance of Caché from 2015.1 to 2017.1. A terminal session launched from the server's desktop cube was unable to run OS-level commands using the $ZF(-1) function. For instance, using the no-op command "REM" as follows:

write $zf(-1,"rem")

was returning -1, indicating that the Windows command could not be issued.

It turned out that their original 2015.

Hi Guys,

I'm a newbie that doesn't know much about integratedML and looking for a first push into it, I've setup VSCode with my IRIS 2024.3 running in Linux and my understanding is that we can create models using SQL, so first, do I need to setup a specific environment where I can run my SQL commands to create & train Models or just using SMP, and do I need to install or enable Python ..etc things required to setup the environment?

Then if there are easy samples or training materials on how to create, train & deploy my model?  

Thanks
