Hi Folks!

Have a very simple question, I hope :)

How can I make sure that user 'John' is already created in the IRIS system?

Preferabbly via SQL?

thanks a lot!

Using Flask, REST API, and IAM with InterSystems IRIS

Part 2 – Flask App

Flask is a web development microframework written in Python. It is known for being simple, flexible, and enabling rapid application development.

Installing Flask is very simple. Once you have python installed correctly on your operating system, we need to install the flask library with the pip command. For REST API consumption, it is advisable to use the requests library. The following link provides a guide to installing flask: https://flask.palletsprojects.com/en/stable/installation/

Using Flask, REST API, and IAM with InterSystems IRIS

Part 1 - REST API

Hello

In this article we will see the implementation of a REST API to perform the maintenance of a CRUD, using Flask and IAM.

In this first part of the article we will see the construction and publication of the REST API in Iris.

First, let's create our persistent class to store the data. To do this, we go to Iris and create our class:

Hi,

Is it possible to change the WebGateway Port i.e. from i.e. 57773 to 443 to use it as:

https://myserver/iris/csp/sys/%25CSP.Portal.Home.zen.....etc.

Meaning: https://myserver:443/iris/csp/sys/%25CSP.Portal.Home.zen

Are there any known problems or other suggestions? 

As you might have heard, we just introduced the InterSystems API Manager (IAM); a new feature of the InterSystems IRIS Data Platform™, enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement.

In this article, I will show you how to set up IAM and highlight some of the many capabilities IAM allows you to leverage.

Hi all,

I have a passthru REST setup using EnsLib.HTTP.GenericService and EnsLib.HTTP.GenericOperation. Works well.

I am adding some logic to the Operation and for some scenarios I want to return an HTTP 40x response status code.

I create an httpResponse object within the Business Operation, but I can't figure out how to set the http response status code that is returned to my Posstman client that initiated the request. I set StatusCode=400, and StatusLine and ReasonPhrase properties - but when the ultimate requestor (Postman) receives the response back it is a 200 status code.

Hello everyone,

How can i download the iris odbc for linux ubuntu in order to recover the file 'libirisodbcu.so'.

thanks in advance

Hey everyone, 
Might be a stupid question, but i was trying to set the ContentLength of the %response object in my website.
In different places (like the onPreHttp / onPostHttp etc) but none seems to work.
The reason behind it is to send a more accurate representation of the actual data I send, instead of having the overhead of the broker that adds more characters , I want the exact length of the response accounting only for the data that I actually returned.

Hey everyone.

As I have been working with IRIS (nee Caché) for some time now, I decided to take a look at how I manage things like functions and scripts that may not belong to a single namespace or environment, but should still have a home.

I have taken to creating a github repo where I can keep track of a single .cls of "general functions" that I can then drop into an environment when required.

Using SQL Gateway with Python, Vector Search, and Interoperability in InterSystems Iris

Part 2 – Python and Vector Search

Since we have access to the data from our external table, we can use everything that Iris has to offer with this data. Let's, for example, read the data from our external table and generate a polynomial regression with it.

For more information on using python with Iris, see the documentation available at https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=AFL_epython

Let's now consume the data from the external database to calculate a polynomial regression. To do this, we will use a python code to run a SQL that will read our MySQL table and turn it into a pandas dataframe:

Using SQL Gateway with Python, Vector Search, and Interoperability in InterSystems Iris

Part 1 - SQL Gateway

Hello

In this article we will look at the use of SQL Gateway in Iris. SQL Gateway allows Iris to have access to tables from other (external) database via ODBC or JDBC. We can access Tables or Views from various databases, such as Oracle, PostgreSQL, SQL Server, MySQL and others.

Hi Community,

Enjoy the new video on InterSystems Developers YouTube:

⏯ Make Upgrades Easier - Introducing the Upgrade Impact Checklist @ Global Summit 2024

First, let me wish the developer community a Happy New Year! We hope to bring you many good things this year, and today I'd like to introduce the latest version of the Intersystems Language Server extension to VS Code. Most Language Server improvements are experienced via the ObjectScript extension UI, so you many not be aware of the many improvements in areas like Intellisense and hover overs that were released throughout 2024. Please take a quick read over the Language Server's CHANGELOG and find out what you missed. Most recently, version 2.7.

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop  this job.

Where is InterSystems IRIS Download for Windows (better free)?

Hi Community,

We're excited to invite you to the webinar Configuring a Web Server for use with InterSystems IRIS.

Join this webinar for an engaging and insightful tech talk on the configuration of a web server to use with InterSystems IRIS.

⏱ Date & Time: Thursday, February 27, 10:30 AM GMT

👨‍🏫 Speaker: @Steve Mallam, HealthShare Team Lead, InterSystems UK&I

The IKO allows for sidecars. The idea behind them is to have direct access to a specific instance of IRIS. If we have mirrored data nodes, the web gateway will (correctly) only give us access to the primary node. But perhaps we need access to a specific instance. The sidecar is the solution.

Building on the example from the previous article, we introduce the sidecar by using a mirrored data node and of course arbiter.

apiVersion: intersystems.

In the WRC, we frequently see customers contact us because their Web Gateway is unable to serve web pages. This article will explain a frequent reason why these errors can occur, and explain some tools which can be used to debug the problem. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

Hello Community,

Is it possible to track or determine where the global variable was set (routine or class) in a form of like label+offset^routine?

Learning LLM Magic

The world of Generative AI has been pretty inescapable for a while, commercial models running on paid Cloud instances are everywhere.  With your data stored securely on-prem in IRIS, it might seem daunting to start getting the benefit of experimentation with Large Language Models without having to navigate a minefield of Governance and rapidly evolving API documentation.   If only there was a way to bring an LLM to IRIS, preferably in a very small code footprint.

I set up all the credentials and IP, Port, Namespace, SSL/TLS Server Name and .ini file but I still cannot connect to db. and It says 

Iris ODBC][State : 08S01][Native Code 459]
[C:\Windows\system32\odbcad32.exe]
Connection via irisconnect failed: 
Matching SSL server config not found in ssldefs.ini or registry

In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

These exceptions are different from %Status, so you can't directly/efficiently use the exception object with $SYSTEM.OBJ.DisplayError() or $SYSTEM.Status.DisplayError().

My usecase is sorting and removing duplicates and getting count from a file that has json messages as a individual rows.

I am currently planning to use pandas for this purpose as its really fast.

You may encounter errors during any point of program execution, and there are several ways to raise and handle these exceptions. In this article, we'll explore how exceptions are handled efficiently in IRIS.

One of the most commonly used return types is %Status, which is used by methods to indicate success or failure. Let's begin by discussing %Status values.

Working with %Status

The %Status return type is used to represent errors or success. Many system methods return %Status when an error occurs.

Overview

With the help of SQL, you can build, train, and manage machine learning models directly in the database with InterSystems IRIS's robust IntegratedML tool. Using SQL examples that represent your data, we will go over IntegratedML configuration and how it is used in practical situations in this article.

Why am I writting this?

Last year I made an article for starters on using embedded python. Later, it started a little discussion on how to return values with python and I found some interesting observations that are worth writing a little article. Also, hopefully I can reach more people by writing this.

Possible situations

There are two things you'll need to care about when returning a value with python. The first is the type you're trying to return and the second is where you're returning it.

Hello, I have a problem with a call and I would need some help.

When I call an API with the SendFormDataArray method of the EnsLib.HTTP.OutboundAdapter adapter, I pass it a %Net.HttpRequest object and I receive the following error:

ERROR #5002: ObjectScript error: <SUBSCRIPT>MatchSuffix+1^%Net.HttpRequest.1 ^%qPublicSuffix("")

I have correctly entered the url in my business operation and I pass it in the last parameter of the SendFormDataArray method. Do you have any idea, please?

Method XRPUAuthentification(pInput As ANCV.msg.BO.XRPUAuthentificationDmde, Output pOutput As ANCV.msg.BO.

From the previous article, we identified some issues when working with JSON in SQL.

IRIS offers a dedicated feature for handling JSON documents, called DocDB.

InterSystems IRIS® data platform DocDB is a facility for storing and retrieving database data. It is compatible with, but separate from, traditional SQL table and field (class and property) data storage and retrieval. It is based on JSON (JavaScript Object Notation) which provides support for web-based data exchange. InterSystems IRIS provides support for developing DocDB databases and applications in REST and in ObjectScript, as well as providing SQL support for creating or querying DocDB data.

By its nature, InterSystems IRIS Document Database is a schema-less data structure. That means that each document has its own structure, which may differ from other documents in the same database. This has several benefits when compared with SQL, which requires a pre-defined data structure.

The word “document” is used here as a specific industry-wide technical term, as a dynamic data storage structure. “Document”, as used in DocDB, should not be confused with a text document, or with documentation.

Let's explore how DocDB can help store JSON in the database and integrate it into projects that rely solely on xDBC protocols.
