InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

All time

I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.

So far it looks like my options are:

Some changes in IRIS configuration require a restart of IRIS.
This is no big issue as long as I have access to the server command line with sufficient privileges.

In a container, this is not always given.
Stopping IRIS from the terminal/session prompt is no problem.
But the restart after is.

Note1: container start-stop is no option as it might be removed by option --rm in docker run
Note2: the target is linux (manly in docker). Windows is excluded

Last week saw the launch of the InterSystems IRIS Data Platform in sunny California.

For the engaging eXPerience Labs (XP-Labs) training sessions, my first customer and favourite department (Learning Services), was working hard assisting and supporting us all behind the scene.

Hello everyone,
It is my first post in the community. Very recently I started working using IRIS, creating services with Cache.
Today they gave me a new task and I'm really lost.

How can I use an oracle database to create services using iris?

Throughout the day I was looking for a guide to use a remote Oracle database. but unfortunately I only managed the connection in SQL Gateway

Four Database APIs

A concurrent session in IRIS:
SQL, Objects, REST, and GraphQL

Kazimir Malevich, "Athletes" (1932)

"But of course you don't understand! How can a person who has always traveled in a horse-drawn carriage understand the feelings and impressions of the express traveler or the pilot in the air?"

Kazimir Malevich (1916)

Introduction

We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills?

There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex.

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Configuring IRIS autostart on Linux

For practical reasons, it may be desirable that after a Linux server restart, the IRIS instance is automatically started.

Below you will find the steps to follow to automate the startup of IRIS during a reboot of the Linux server, via systemd :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

Hi guys,

My client has a requirement to add a column of random numbers to the query result.

I wrote a function as below:

Class Utils.SqlUtility Extends %RegisteredObject
{

ClassMethod GetSomeNumber(intInput As %Integer) As %Integer [ SqlName = GetNumber, SqlProc ]
{
Return $R(intInput)
}

}

But in the returned sql result, every row share the same value, as below,

SELECT Utils.GetNumber('456'),
ID, Citizenship, DOB, FirstName, Gender, IDNumber, LastName, PatientNumber, PhoneNumber
FROM CDR.Patient

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

How to send messages to Microsoft Teams

Hi community,

The aim of this article is to explain how to create messaging between IRIS and Microsoft Teams.

In my company, we wanted to monitor error messages, and we used the Ens.Alert class to redirect those error messages through a Business Operation that sent an email.
The problem was that we sent those error messages to a support account where there were many emails. We wanted something specific for a specific team.

So we investigated how to make these messages reach the development team directly and they could have, in real time, a notification of an error in our production.
In our company we use Microsoft Teams as a corporate tool, so we asked ourselves: How could we make these messages reach the IRIS development team?

Now available on Open Exchange is a library of third party charts available to use within DeepSee/InterSystems IRIS BI dashboards. To start, simply download and install, select the new portlet as the widget type, then select the chart type that you desire. If you don't find the type of chart you are looking for, you can easily extend the portlet to implement your desired chart type. These new chart types can be used within existing dashboards or you can create new dashboards using them.

I have defined a class with a dynamic object property:

My class

The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):

Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1

Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.

$ZSTORAGE is set to -1.

Hi Developers!

A question to those who use VSCode to code InterSystems ObjectScript.

Suppose you have the ObjectScript code on IRIS server and you want to export it into the desired folder.

And you have VSCode connected to the server.

What is the way to tell VSCode that I want to export classes into some particular folder in /package/class.cls way?

E.g. into:

/project_folder/src/cls/Package/class.cls

and project_folder is opened in VSCode as the folder of the project.

more usefull Object Dump

During testing your code you are often confronted with the need to examine
the actual content of an object. Either using ZWRITE or $system.OBJ.Dump()
you get a picture of simple properties as "--- attribute values ---"
while "--- swizzled references ---" are more confusing than informative
and with "--- calculated references ---" you are just left in the lurch.

This small helper class allows you to dump an object to terminal or
e.g in background to some stream for later review.
By default, you see just properties with content,

At the George James Software booth at Global Summit last year we took the wraps off the work we've been doing to make our popular editing and debugging tool Serenji available on the Visual Studio Code platform.

Rather than requiring you to pull code from your namespaces into local files, then push the changes back to the namespace to run it, you work directly in the namespace. In other words, the editing experience is like Studio rather than like Atelier.

As well as editing code you can also debug it directly from VSCode.

Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!
