Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ HealthShare Analytics Solution: So Many Tools, So Much Power @ Global Summit 2022

InterSystems announces its fifth preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Highlights

Many updates and enhancements have been added in 2023.2 and there are also brand-new capabilities, such as Time-Aware Modeling, and enhancements of Foreign Tables (but still as an experimental feature). Note that some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the installers.

Based on your experience, do you know any reason why IRIS would enter a deadlock/hang state ? 

When such thing occurs, it's no more possible to connect to Portal or Studio, despite IRIS service (IRIS.EXE processes) being still active. CPU/memory/network usage are usually very low (eg: it does not occurs because server is overloaded). The only fix is a full restart of IRIS (eg: by clicking on IRIS icon in notification toolbar and choosing appropriate action).

I had that issue on a production server a few weeks ago.

Hi guys, 

I want to develop a web application in which a user can log in through the user credential of intersystems that is created in Management Portal for a specific role. How can I authenticate the user and get any token or login cookie through which user can call other apis

InterSystems FAQ rubric

The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.

In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages ​​such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.

Hi Community,

Please give me an example on how to configure email alerting based on the rules and send out emails accrordingly.

As a message comes into the business service component I want to check specific fields and if a field for example active = true i want to send it to a different email and if active = false I want to send it to a different email as well.

Guide me on how to accomplish this requirement and let me know if InterSystems uses a default SMTP server or I must have that server in place.

Regards

Hi all,
I am creating a property in my class something like below. I want to initialize it to 0.00 this a default value.

Property currentLimit As %Numeric(SCALE = 2);

What is the difference between iris2021 and IRIS2020

I am having a datatype DATE value from db 41966. And I want to convert it to epoch time.
Also, in case of DATETIME value how can I convert it to epoch.

The Caché epoch is January 1, 1840  and the Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 . How do you convert the current date and time to Unix epoch time?

Good day,

Is there a way to change the theme in management portal? or at least the color of the header.

Issue is, some users have access to Development and Testing and Production environments. I would like a way to color-differentiate the environments to reduce the errors. 

VS Code has a powerful snippets capability, and its Marketplace offers a way for developers to publish their snippets so others can use them. However, publishing on Marketplace takes some effort and snippets targeting InterSystems coders will realistically only be of interest to a very small number of Marketplace visitors.

This inspired me to create oex-vscode-snippets-template, a GitHub template for creating repositories dedicated to publishing code snippets for InterSystems devs.

NOTE:  This content was originally presented at the InterSystems Global Summit in 2014, however related topics often come up on the Developer Community so I have decided to turn this into an article for easier reference and discussion.  However, much of the content was pulled directly from the presentation slides so the article format resembles that of a PPT deck more than paragraphs.

Introduction

Teams that deal with many environments (e.g. for development, testing and production) multiplied by many systems (e.g.

Are you all ready for something you wish you knew ages ago (or, in my case, a DECADE ago)?  Open up a portal in your favorite instance and go to:

System Administration->Configuration->Additional Settings->Startup

Scroll down to "Terminal Prompt" and click 'Edit'.  This allows you to edit what you see on your terminal prompt.  You can change that to my current setting: 8,3,2

What does this do?  It adds your instance name for your prompt.

InterSystems is currently looking for a U.S.-based Developer and Startup Evangelist!

Are you a strong developer who loves writing, speaking and teaching other developers about technology while taking a meaningful role in shaping the experience they have with the platform itself?

As you know, if you regularly read the articles that are published in the Community, last May InterSystems organized the JOnTheBeach2023 Hackathon held in Malaga (Spain). The topic that was proposed was the use of predictive analysis tools that InterSystems IRIS makes available to all developers with IntegratedML. We must thank both @Thomas Dyar and @Dmitry Maslennikov for all the work and effort they put into making it a resounding success.

Problem

In a fast-paced clinical environment, where quick decision-making is crucial, the lack of streamlined document storage and access systems poses several obstacles. While storage solutions for documents exist (e.g, FHIR), accessing and effectively searching for specific patient data within those documents meaningfully can be a significant challenge.

Motivation

AI has made document search remarkably powerful. Question and answering over docs has never been easier with open-source tools like Chroma and Langchain to store and use vector embeddings to query across Generative AI APIs.

Introduction

A password manager is an important security tool that allows users to store and manage their passwords without the need to remember or write them down in insecure places. In this article, we will explore the development of a simple password manager using the Flask framework and the InterSystems IRIS database.

Key Features

Our password manager application will provide the following key features:

1. User registration with account creation.
2. User authentication during login.
3. Adding new passwords with a title, login, and password.

This project is implemented as a tool for viewing temperature data taken from a temperature sensor installed in Rasperry PI and located in a remote place where there is Internet, for example, in dacha.

The module for regular reading and sending information is implemented in python and is built in the same project. If the temperature in the country house becomes lower or higher than the threshold values, then a notification will be sent to the telegram channel.

Our objective

In the last article, we talked about a few starters for Django. We learned how to begin the project, ensure we have all the requisites, and make a CRUD. However, today we are going a little further. 
Sometimes we need to access more complex methods, so today, we will connect IRIS to a Python environment, build a few functions and display them on a webpage. It will be similar to the last discussion, but further enough for you to make something new, even though not enough to feel lost.

I want to get SOAP Location details dynamically from Management portal using Property value?

Is there any idea to get it? Any example please?

As an AI language model, ChatGPT is capable of performing a variety of tasks like language translation, writing songs, answering research questions, and even generating computer code. With its impressive abilities, ChatGPT has quickly become a popular tool for various applications, from chatbots to content creation.
But despite its advanced capabilities, ChatGPT is not able to access your personal data. So in this article, I will demonstrate below steps to build custom ChatGPT AI by using LangChain Framework:

Hello Community!

The Global Summit 2023 in Hollywood has just ended but keynotes are already available for those who missed them while being on the premises or who couldn't attend this in-person event at all for some reason or another (or just for those who wish to refresh their memory and listen to them again).

Enjoy watching all the keynotes from all three days of Global Summit 2023 via this YouTube playlist: 

Hi all,
I am using ExecDirect() method to execute my SQL query which is something like "SELECT * from Account where AccountNumber = ? "
But when I am providing a accountnumber that don't exists it doesn't return anything as aspected. while I am trying to check resultset.%SQLCODE in this case it is giving me 0 not 100. What's wrong with my SQL query and Also I there any other Property through which I check for if my resultset is null or it has some values.

Prediction of server configuration for entry

The platform server entry configuration prediction application connects to Iris in Java and uses its Integrated ML technology to analyze data such as hospital outpatient volume, number of services, number of messages, and message save time. It can predict the server configuration required for the hospital entry platform before the hospital integration platform enters, providing convenience for customers.

 It's time for a Code Golf round!

Isogram 

A word or phrase that has no repeating letters, consecutive or non-consecutive.

Implement a method that checks if the received string is an isogram or not.
Assume the empty string is an isogram. 
Ignore the letter case.

Allowed inputs: A-Z, a-z.

As usual, the shortest solution wins!

In show Query messages in the message viewer the head.%Id is always used. How do you do this via your own sql/objectscript as fast as the portal does a search as using dates searching Ens.MessageHeader on portal is slow. 

For instance if you try do a search saying (TimeProcessed >='2023-06-01 00:00:00.000' and TimeProcessed <'2023-06-02 00:00:00.000') it is slow but using the portal the search would know this is head.%ID >= 5344549861 AND head.%ID <= 5347641372. How do you utilize this in your own queries as can't see the logic in EnsPortal.MsgFilter.Assistant 

I'm having trouble adjusting the protocol used for any CSP Requests. Currently all request to the system are sent over HTTP 1.1

When loading 40+ images on a page, the browser starts stalling request. According to google HTTP 1.1 only allows 6 parallel TCP Connections before suspending the remaining. 

I have looked through the Web Gateway Settings, %Net.HttpRequest.HTTPVersion and SSL Configuration but haven't found anything.

Is there a hidden setting that can be changed? Does Caché even support higher HTTP protocols. We do have an IRIS development instance I could test on.
