Deltanji webinar: source control designed for change, built for you.

Is your source control treating your InterSystems IRIS environment like a simple collection of files? Most source control tools lack the native intelligence to handle InterSystems IRIS, which is why your code is treated as such. 

Deltanji is different. It understands how code and other artifacts are stored within IRIS and can manage them directly. This eliminates the friction that other tools introduce to the process. 

Join us for an InterSystems-hosted webinar to see how Deltanji provides an enterprise-grade source control solution that is tightly integrated with your IRIS environment.

Difference between Extending EnsLib.SQL.Snapshot vs creating a Property for EnsLib.SQL.Snapshot

We are working on Disk Consolidation and looking at Class/Globals that are rather large and not being cleaned up by the nightly Purge process. We have implemented DeleteHelper - A Class to Help with Deleting Referenced Persistent Classes | IDC on any Custom Data Classes, and Business Processes (BPL).

We have a bunch of Data Classes, BPL's, and Operations that connect to external MS SQL Server using JDBC to query or write data to using Stored Procedures and Queries. All that Query external tables are using EnsLib.SQL.Snapshot, and this is being written to ^Ens.AppData which is not cleaned up.

how can i use left arrow key with if function

Hi all,
I'm trying to learn Intersystems Iris. And I have a question.
How can I use left arrow key with if function. Also if it is possible, teach me that how can I make backspace to edit data?
P.S Sorry for bad English.
new var,key,curPos
w $char(27)_"[2J"_$char(27)_"[H"
s var="12345abcde"
s curPos=$length(var)+1
w $char(27)_"[3;1H"_"First var= "_var
for {
read *key
#; Left Arrow Key
if key="?" {
}
#; Right Arrow Key
elseif key="?" {
}
#; Backspace
elseif key=8 {
}
elseif key=9 {
quit
}
}
w !,"Last var= ",var
Kind Regards,
Ikh

Complementing IRIS with MLflow for a Continuous Training (CT) pipeline

A Continuous Training (CT) pipeline formalises a Machine Learning (ML) model developed through data science experimentation, using the data available at a given point in time. It prepares the model for deployment while enabling autonomous updates as new data becomes available, along with robust performance monitoring, logging, and model registry capabilities for auditing purposes.

InterSystems IRIS already provides nearly all the components required to support such a pipeline. However, one key element is missing: a standardised tool for model registry.

Configuration item disabled, but shows enabled on Namespace

I am trying to built a Task that kicks off a Workflow to pull data into HSPD, and when I try to test the Task

ClassMethod TestTask()
{set tTask = ##class(OSU.Workday.TerminationsTask).%New()set tTask.DaysBack = 1 $$$ThrowOnError(tTask.OnTask())}

I keep getting TestTask+3^OSU.Workday.TerminationsTask.1 *%Exception.StatusException ERROR <Ens>ErrConfigDisabled: Configuration item 'OSU.DataSource.Workday.TermService' is disabled

But within the Namespace the OSU.DataSource.Workday.TermService shows enabled.

Here is my Task that I am using...

Class OSU.Workday.TerminationsTask Extends %SYS.

Considerations when Migrating from Oracle, MSSQL etc to IRIS

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?

Consolidating Risk Management and Compliance Silos in Financial Services

For software engineers and data architects evaluating data platforms for risk and compliance consolidation in financial services.

Overview

Financial institutions typically run separate applications for risk management and regulatory compliance, creating fragmented data landscapes that are difficult to query and expensive to maintain. InterSystems IRIS is a distributed HTAP data platform that allows organizations to consolidate these systems onto a single, unified data layer.

EnsLib.SQL.Snapshot not cleaned during purge messages when used in Response Message

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.

HS.FHIRServer.Interop.Service returning error status code and OperationOutcome

I'm using this service to create a FHIR facade. 
I want to return OperationOutcome to the calling application when I detect an error. 
My code at present is :

set quickStreamOut=##class(HS.SDA3.QuickStream).%New()

set operationOutcome = ##class(HS.FHIR.DTL.vR4.Model.Resource.OperationOutcome).%New()

s issue = ##class(HS.FHIR.DTL.vR4.Model.Element.OperationOutcome.issue).%New()

s issue.severity = "error"

s issue.code = "exception"

s issue.details = ##class(HS.FHIR.DTL.vR4.Model.Datatype.CodeableConcept).%New()

Practical ObjectScript Coding: From JSON to Globals to SQL

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

How to merge existing accounts (update email) in the InterSystems Developer Ecosystem

Hi Community,

Sometimes you may need to merge multiple accounts or simply update the email address you use across the different portals in the InterSystems Developer Ecosystem. Since each portal works a little differently, here’s a guide to help you through the process.

Change your email

If you’d like to use a different email (for example, use a work email instead of a personal one, or vice versa), here’s how to update it across the portals:

1. Update your email in InterSystems SSO. To do this:

Beginner's Guide to %JSON and Dynamic Entities in IRIS

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.
