Only method/routine executed as "do Method..." is included into $ESTACK.
How can I modify a method or routine that returns a value so it can be included in $ESTACK?
Example upon executing via Studio Debug ($ESTACK is converted to string with ">" delimiter):
    Expected: stackstr = %Debugger.System.DebugStub > LogGenerate > Entry > DirChain > Attributes >  LogNew > LogSize >  LogFormat > LogWrite
        Processes DirChain, LogNew, LogSize, LogFormat are executed as "If Method..."
        Process Attributes is executed as "set a = Attributes..."
    Current: stackstr =  %Debugger.

Hi All,

First I want give a Shout Out to @Theo Stolker  and @Rupert.Young. Because they helped me with the solution.

 When you're using the EnsLib.SQL.Snapshot as a Property in the Response Message to return Snapshot data (,e.g.: from Business Operation to Business Process,) the Snapshot data won't be cleaned with the Purge messages task/service.

Class ResponseMessage Extends Ens.Response

{

    Property SnapshotProp As EnsLib.SQL.Snapshot;

}

The data will be stuck in the global: ^Ens.AppData. You can find it with this query in System>Globals:  ^Ens.AppData("EnsLib.SQL.

Hi everyone,

I'm dealing with a situation where LOAD DATA operations — especially large batches with data inconsistencies — are consuming a lot of disk space. I've noticed that the same error messages are being repeatedly logged in the %SQL_Diag.Result and %SQL_Diag.Message tables, which is significantly increasing the size of the database.

One idea was to move these diagnostic tables to a separate database with a configured size limit, but before going down that path, I'd like to ask:

Is there a simpler or more efficient way to handle this?
For example:

• Can we limit the number of repeated logs?

Environment:
    Targeted *.inc file (with hundreds of defined macros) is in use throughout the application and included into every class declaration.
    Statement "set a = $$$TestIf(3)" is included into a classmethod with no other code in. Expected output 5
Same macro options in *.inc:
    #define TestIf(%arr)    if %arr>0 QUIT 5
    #define TestIf(%arr)    if (%arr>0) {QUIT 5}
Issue:
    failure to compile class with the same error on all tried definition options as:

HTTP and HTTPS with REST API

Hello

The HTTP protocol allows you to obtain resources, such as HTML documents. It is the basis of any data exchange on the Web and a client-server protocol, meaning that requests are initiated by the recipient, usually a Web browser.

REST APIs take advantage of this protocol to exchange messages between client and server. This makes REST APIs fast, lightweight, and flexible. REST APIs use the HTTP verbs GET, POST, PUT, DELETE, and others to indicate the actions they want to perform.

When we make a call to a RESt API, what actually happens is an HTTP call. The API receives this call and according to the requested verb and path, the API performs the desired action. In the case of the Iris implementation we can see this clearly in the URLMap definition area:

Introduction

In InterSystems IRIS 2024.3 and subsequent IRIS versions, the AutoML component is now delivered as a separate Python package that is installed after installation. Unfortunately, some recent versions of Python packages that AutoML relies on have introduced incompatibilities, and can cause failures when training models (TRAIN MODEL statement). If you see an error mentioning "TypeError" and the keyword argument "fit_params" or "sklearn_tags", read on for a quick fix.

Root Cause

• scikit-learn updated to version 1.6.0, deprecating fit_params.

Yes, yes! Welcome! You haven't made a mistake, you are in your beloved InterSystems Developer Community in Spanish.

You may be wondering what the title of this article is about, well it's very simple, today we are gathered here to honor the Inquisitor and praise the great work he performed. 

So, who or what is the Inquisitor?

Perfect, now that I have your attention, it's time to explain what the Inquisitor is. The Inquisitor is a solution developed with InterSystems technology to subject public contracts published daily on the platform  https://contrataciondelestado.es/ to scrutiny.

InterSystems ObjectScript extension for VS Code, version 3.0.1

Am also asking this question on the extension's GitHub page: Request textDocument/documentSymbol failed. Error: name must not be falsy · intersystems-community/vscode-objectscript · Discussion #1530 - but suspect more eyes will see it here, which might help gather additional information.

Tried to compile some legacy ObjectScript code via Import/Compile in VS Code using the vscode-objectscript extension. Getting an error, and the content of the file is left changed on the filesystem simply by being compiled.

We require automatic injection of security predicates at runtime, depending on the user or API token. Is there a supported or hackable mechanism to manipulate SQL parsing/compilation before execution?

Hi, 

We very much appreciate the interest in the Developer Community for IRIS Vector Search and hope our technology has helped many of you build innovative applications or advanced your R&D efforts. With a dedicated index, integrated embeddings generation, and deep integration with our SQL engine now available in InterSystems IRIS, we're looking at the next frontier, and would love to hear your feedback on the technology to prioritize our investments.

InterSystems IRIS Community Edition HAOS Add-On

Run InterSystems IRIS inside of Home Assistant, as an add-on.  Before you dismiss this article possibly under the guise that this is just a gimmick, Id like you to step back and take a look at how easy it is to launch IRIS based applications using this platform.  If you look at Open Exchange, you will see dozens of dozens of applications worthy of launching while they are basically hung out to dry as gitware, and launchable if you want to get into a laptop battle with containerd or Docker.  With a simple git repo, and a specification, you can now build your app on IRIS, and make it launchable through a marketplace with limited hassle to your end users.  Run it along side Ollama and the LLM/LAM implementations, expose anything in IRIS as a sensor or expose an endpoint for interaction in your IRIS app to interact with anything you've connected to HAOS.  Wanna restart an IRIS production with a flick of a physical switch or Assisted AI? You can do it with this add-on, or your own, right alongside the home automation hackers.

The first part of this article provides all the background information. It also includes links to the DATATYPE_SAMPLE database, which you can use to follow along with the examples.

In that section, we explored an error type ("Access Failure") that is easy to detect, as it immediately triggers a clear error message when attempting to read the data via the database driver.

The errors discussed in this section are more subtle and harder to detect.

What is TLS?

TLS, the successor to SSL, stands for Transport Layer Security and provides security (i.e. encryption and authentication) over a TCP/IP connection. If you have ever noticed the "s" on "https" URLs, you have recognized an HTTP connection "secured" by SSL/TLS. In the past, only login/authorization pages on the web would use TLS, but in today's hostile internet environment, best practice indicates that we should secure all connections with TLS.

Why use TLS?

So, why would you implement TLS for HL7 connections?

Hi all,

Let's do some more work about the testing data generation and export the result by REST API.😁

Here, I would like to reuse the datagen.restservice class which built in the pervious article Writing a REST api service for exporting the generated patient data in .csv

This time, we are planning to generate a FHIR bundle include multiple resources for testing the FHIR repository.

Here is some reference for you, if you want to know mare about FHIR The Concept of FHIR: A Healthcare Data Standard Designed for the Future

OK... Let's start😆

1. Create a new utility class datagen.utli.

I have an API set up in IRIS which is secured using an IRIS authentication service, so there is a bearer token being passed down in the request header.

I've already set Parameter HandleCorsRequest = 1; on the spec class and All the endpoints I am have (a mix of GET, POST, PATCH and DELETE) are working from postman without issue, the problem is when consuming from the web front-end and the preflight checks the browser instigates. Most of the endpoints work in the browser, but some are triggering the preflight (OPTIONS) check causing the CORS issue.

Hello all,

I'm trying to build a cube based on a linked table but seems that IRIS is not able to do it :O

Long story short, I have a linked table in IRIS that sources a Microsoft SQL table (using standard linked feature from the portal). It works fine, I can access it using SQL as many other times. On top of that, I've created in DeepSee (ok, Analytics) a cube that uses this class as source. It compiles correctly, no errors given. When I build it with 100 records, all goes well and using Analyzer I can see results.

Existing cube deleted.

Hi experts

I'm trying to configure an IRIS ODBC connection with "Windows NT authentication using the network login ID". I have created the System DSN as below:

and user (PROD\test) in the SQL Gateway connection 

However, as the error message suggests, IRIS is trying to connect with PROD\svc_mist, rather than PROD\test configured above. 

Is there anyway to configure the ODBC connection with specified account with Windows Auth method? 

I was facing the same issue as Jerry faced when connecting IRIS to SQL server. My ODBC connection is configured to authenticate via windows authentication.

Configure IRIS ODBC connection with Windows authentication using a
 

How I fixed it for myself?

Root cause

• The SQL Server DSN was set to Windows Integrated Authentication.
• IRIS opens the ODBC connection via irisdb.exe, which runs under the IRIS Windows services’ logon account.
• My IRIS services were running as LocalSystem, so SQL saw the machine account<ORGNAME>\<ASSETID>$.

Folks!

Recently I found several one-line long ObjectScript commands on DC and think that it'd be great not to lose it and to collect more!

So I decided to gather a few first cases, put in one OEX project, and share them with you!

And here is how you can use them.

1. Create client SSL configuration.

set $namespace="%SYS", name="DefaultSSL" do:'##class(Security.SSLConfigs).Exists(name) ##class(Security.SSLConfigs).Create(name)

Useful if you need to read content from an URL.

Don't forget to return to a previous namespace. Or add 

n $namespace

before the call.

If you start with InterSystems ObjectScript, you will meet the XECUTE command.
And beginners may ask: Where and Why may I need to use this ?

The official documentation has a rich collection of code snippets. No practical case.
Just recently, I met a use case that I'd like to share with you.

The scenario:

When you build an IRIS container with Docker, then, in most cases,
you run the  initialization script  

iris session iris < iris.script 

This means you open a terminal session and feed your input line-by-line from the script.
And that's fine and easy if you call methods, or functions, or commands.

Overview 

This release focuses on upgrade reliability, security expansion, and support experience improvements across multiple InterSystems Cloud Services. With this version, all major offerings—including FHIR Server, InterSystems Data Fabric Studio (IDS), IDS with Supply Chain, and IRIS Managed Services—now support Advanced Security, providing a unified and enhanced security posture.

I am regularly contacted by customers about memory sizing when they get alerts that free memory is below a threshold, or they observe that free memory has dropped suddenly. Is there a problem? Will their application stop working because it has run out of memory for running system and application processes? Nearly always, the answer is no, there is nothing to worry about. But that simple answer is usually not enough. What's going on?

Consider the chart below. It is showing the output of the free metric in vmstat.

Hi all,

This is a quick tip about how to use case insensitive URL in REST API.

If you have a class that extends from %CSP.REST and Ens.BusinessService, to create a REST API service, and you have defined your WebApplication in lowercase

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
    <Route Url="/user" Method="POST" Call="User"/>
    <Route Url="/login" Method="POST" Call="Login"/>
</Routes>
}

Only accepts the url in lowercase, i.e. http://myserver/myproduction/user

If you have any uppercase character, the url doesn't work.

Hi,

I'm trying to run some scripting in Windows. I'm using an instance of the IRISHealth community. 

I'm just trying to run a simple sequence of commands so I can run irissession in a non-interactive mode, like:

irissession.exe IRISHEALTH -U "%SYS" < "myprogram.iris"

set$namespace="%SYS"set cbk = "C:\Test1.cbk"set log = "C:\Test1.

Hello community,

I wanted to share my experience about working on Large Data projects. Over the years, I have had the opportunity to handle massive patient data, payor data and transactional logs while working in an hospital industry. I have had the chance to build huge reports which had to be written using advanced logics fetching data across multiple tables whose indexing was not helping me write efficient code.

Here is what I have learned about managing large data efficiently.

Choosing the right data access method.

As we all here in the community are aware of, IRIS provides multiple ways to access data. Choosing the right method, depends on the requirement.

• Direct Global Access: Fastest for bulk read/write operations. For example, if i have to traverse through indexes and fetch patient data, I can loop through the globals to process millions of records. This will save a lot of time.

Set ToDate=+HSet FromDate=+$H-1ForSet FromDate=$O(^PatientD("Date",FromDate)) Quit:FromDate>ToDate  Do
. Set PatId=""ForSet PatId=$Order(^PatientD("Date",FromDate,PatID)) Quit:PatId=""Do
. . Write$Get(^PatientD("Date",FromDate,PatID)),!

• Using SQL: Useful for reporting or analytical requirements, though slower for huge data sets.
