Background
InterSystems IRIS 2019 is going to introduce new and exciting features. One of the areas with new interesting must-to-know things is the API Management.
InterSystems IRIS
Description
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.

InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time.
Hi all. Today we are going to upload a ML model into IRIS Manager and test it.
Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, Python 3.6.5.
Introduction
These days many available different tools for Data Mining enable you to develop predictive models and analyze the data you have with unprecedented ease. InterSystems IRIS Data Platform provide a stable foundation for your big data and fast data applications, providing interoperability with modern DataMining tools.

Terminal scripts can be used to run pre-designed commands on the terminal, like a batch file. You can write anything that can be executed on terminal, like for loop, if else and so on, inside Terminal scripts. In this article, I will show you how to call Terminal scripts, how to use parameters in Terminal scripts and how to avoid session disconnected when running Terminal scripts. If you have any information about how to use Terminal scripts or you have any feedback, please feel free to leave a comment.

IRIS brought us a new WOW feature - SHARDING !
Definitely a great thing!
But how can I find out if it suits my actual applications?
Is there a practical advantage to go for it with my well cooked transactional application?
Or is it just for new still to be designed applications?

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.
In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

IRIS is a powerful platform and one of the new features is the Java Business Host (DOC: Connecting Systems Using Java Business Hosts) that allow you to develop Business Services and Business Operations directly in Java (JavaDocs of the InterSystems Gateway Package).

There's a new and exciting enhancement to QEWD that has just been released - it's an additional layer of abstraction known as QEWD-Up. QEWD-Up hides away all the mechanics of QEWD itself, allowing you to focus on just your REST APIs and the code that implements them.
Additionally, and importantly, QEWD-Up simplifies the maintenance of your REST APIs, allowing you (and others) to quickly and easily understand their life-cycle and implementation.

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!

Hi Community!
We are pleased to invite you to the upcoming webinar "Using Blockchain with InterSystems IRIS" on 20th of December at 10:00 (Moscow time)!

The question has come up several times and I saw mixed answers and no quick example
My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

Hi,
I want to test the node.js interface to iris with trial sandbox. The node.js documentation refers to get de node package from the instance bin directory. As I'm trying to use the trial sandbox I don't have access to the directory. Please let me know where I could download iris.node package.
Thanks,
Fabian

Hi Community!
We try a new approach to the InterSystems Developers YouTube Videos called "Coding Talks"!
Coding Talks is a short video in which the developer demonstrates a particular feature or functionality of InterSystems Data Platforms which he/she uses to in coding. Typical format: the face on side and editor with ObjectScript.
Check this video I made by myself participating in Advent of Code 2018 and coding with InterSystems ObjectScript in VSCode.
Coding Advent of Code 2018 Using InterSystems ObjectScript
As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.
QEWD.js is, of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript.

Hello experts,
I am new to IRIS and I was told I could get a great hands-on experince with the commuity edition that is currently availabe on mutliple cloud providers.
Unfortunately connecting Atelier to the given IRIS instance has been unsuccessful:

I have a persistent class that represents cities across the United States. It is below, but basically has a City Id, Name, Lat, Lon and a few other unimportant fields for this issue. Anytime I attempt to query on the Latitude or Longitude it immediately returns no results. My first thought was that it was a casting issue so I tried casting both sides to floats, ints, even strings and in all cases it immediately comes back with no results. I then decided to cast it to a string and attempt a like statement thinking it might be something about how floats are handled, but still no joy. Any

Hi guys,
Mostly the title. Let's say my commands are stored in a text file "inFile". Here was my best guess:
<dir to iris> console IRIS2018 <inFile
For reference, here's an example of the analogous structure that works on Cache:
C:\InterSystems\Cache2018\bin\cache -s C:\InterSystems\Cache2018\mgr -U <namespace to start as> <inFile

Did you know that Caché (and now InterSystems IRIS) has available parser for ObjectScript ?
Well, technically, lexer. It hides under the name of %SyntaxColor class. This class provides API to the DLL used by Studio to do syntax highlighting. As a result if works only under Windows.
Last comment 3 December 2018
It was mentioned in an earlier version of the IRIS documentation that IRIS and Cache should not be installed on the same physical server (port clashes?).
I can't see this warning in the current version of the documentation.
Could someone clarify if this has been resolved in the latest release of IRIS?
Last answer 3 December 2018
I bet that not everyone familiar with InterSystems Caché knows about Studio extensions for working with the source code. You can actually use the Studio to create your own type of source code, compile it into interpretable (INT) and object code, and sometimes even add code completion support. That is, theoretically, you can make the Studio support any programming language that will be executed by the DBMS just as well as Caché ObjectScript. In this article, I will give you a simple example of writing programs in Caché Studio using a language that resembles JavaScript. If you are interested, please read along.

Hi,
I need to route a message synchronously to multiple targets using a routing rule.
In IRIS I built a general routing rule set, made up of a couple of rules. For one Rule in particular, and based on a common condition, I want to send the incoming message to 2 different targets. (no transformation is used)
I can select, in the single SEND action, multiple target names, or, I can create consecutive SEND actions, one after the other, each sending to their specific target.

Hi Community!
Consider I have InterSystems IRIS server in a cloud and want to introduce a DR server for it.
Are there any requirements for DR server for InterSystems IRIS if it is in a cloud?
Should it be the same subnet? One private cloud?
Can DR server be placed on another cloud, say Primary on Google Cloud and DR on Azure? Are there any caveats/concerns?
Last answer 14 November 2018 Last comment 16 November 2018
Hi All!
I asked previously about the DR server in the cloud but actually, I'm curious about the backup server to use as analytics server more than for recovery in DR case.
There is a recommended practice to use an async mirror as a server for BI (InterSystems Analytics, DeepSee)
The question is if I have PRIMARY in the cloud (AWS, Google, Azure, etc) "how far" should async mirror member be placed? Same cloud, same private cloud or it doesn't matter at all for analytics purposes?

(Originally posted on Intersystems CODE by @Iain Bray) The following code snippet converts all indices in a package to bitmap indices. The subroutine "test" runs the code:

The data model of your solution based on InterSystems platforms constantly changes over time. But what do you do with the data that was entered before? Back then, the data was valid, but what’s happening to it now after a number of data model changes? The answer to this question can be provided by the IDP DV tool that checks the property data of persistent and serial classes according to the types of these properties. In case any discrepancies are found, the tool generates a detailed error report for the user.
