#InterSystems IRIS

Hi community members!

Please, I'm looking for any references or experiences using InterSystems technologies with MQTT (Message Queuing Telemetry Transport) protocol .

Thanks in advance!

Unconferences have been described as “networking on steroids.” They are the ultimate peer-to-peer discussion experience, and have been a vital part of InterSystems Global Summit for the past few years.

As Visual Report is deprecated in InterSystems IRIS,
What are the best alternatives for reports would you recommend?

Hi,
it is possible to convert a csv file to json file?

I want to stream json files and output the data as it comes in from the files. So my files are "csv" type and I want to convert these files to "json" type.

I can read csv file as follows:

ClassMethod ReadFile()
{
    set stream = ##class(%Stream.FileCharacter).%New()
    set sc = stream.LinkToFile("*.csv")
    do stream.Rewind()
    while'stream.AtEnd {
        set line=stream.ReadLine()
        write line,!
}
What should I add to convert it to "json" and read it again?

Thank you

In the next ten years the applications will radically change, see my vision about it:

Today, the web apps are developed using modern HTML 5/CSS/Javascript frameworks like React, Angular, Bootstrap, etc. These web apps are focused on responsive views from the laptop to tablets and mobile screens.

Hi, Community!

Just want to let you know that InterSystems IRIS is available on Google Cloud Marketplace.

Hey guys,
I need your help.
I am writing a code in Python and I want to create a database and some properties and then to send json files (data) to this database. (I use client-server-model for loading the data into IRIS)
I use curl methods and convert it in Python code with:

curl.trillworks.com/#python

My code so far:
 

I have a class (to be deployed) and I want to forbid anyone from extending it.

Is there any way to do that?

This code snippet allows for a file on the web to be saved into the file system. Specify the server and GET request, as well as the directory the file should be saved to. The class method "test" runs the code:

Class objectscript.saveFileHTTP Extends %RegisteredObject
{
	classmethod test() {
		Set httprequest = ##class(%Net.HttpRequest).%New()
		Set httprequest.Server = "docs.intersystems.com"
		Do httprequest.Get("documentation/cache/20172/pdfs/GJSON.pdf")
    Do $System.OBJ.Dump(httprequest.HttpResponse)
	 
	Set stream=##class(%FileBinaryStream).%New()
	Set stream.Filename="c:\test.pdf"

	Write stream.CopyFrom(httprequest.HttpResponse.Data)
	Write stream.%Save()
}
}

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

• Generation of an AST for a GraphQL request and its validation
• Generation of documentation
• Generation of a response in the JSON format

InterSystems is pleased to announce the availability of InterSystems IRIS Data Platform 2018.1.2 maintenance release

For information about the corrections in this release, refer to the release notes.

Companies today face serious problems in managing their data and delivering strategic value to them. The structure and business logic of data is fragmented into different solutions, architectures and technology platforms. In addition, different project teams, one for each solution, impose their views on the business, limiting the business to which each of these solutions are able to do. The database becomes a simple repository of processed data under the partial view delivered by each application, process, analysis, message and integration.

Hello,

Currently, I'm working with a Java Gateway, and I have the following problem. When importing a class into IRIS, which uses methods from a generic class, I can not find the general methods I need. I'm talking about the test2 method from the class test. How can I import the java method that returns a generic?

(Originally posted by Timur Safin  on Intersystems CODE, 3/2/15) This code snippet is a routine that parses options saved in an arguments array. The subroutine "test" runs the code:

Hi Everyone!

If you are attending VMworld Las Vegas remember to look for two sessions on InterSystems IRIS in the content catalog!

InterSystems is pleased to announce the release of InterSystems IRIS Data Platform 2018.1.1

This is our first follow up to InterSystems IRIS 2018.1.0, released earlier this year.  InterSystems IRIS is a unified data platform for building scalable multi-workload, multi-model data management applications with native interoperability and an open analytics platform.  As a reminder, you can learn more about InterSystems IRIS Data Platform from these Learning Services resources.

Hundreds of fixes have been made in this release:

My understanding is that IRIS is a new technology and does not replace Cache or Ensemble and to that end is more of a modernization than a repackaging. Is that accurate?

Is IRIS and HealthShare heavily penetrated in the payer space of primarily dominate in the provider space? What is the trajectory for InterSystems to penetrate the payer landscape?

Is Terminal access to the InterSystems IRIS Experience sandbox available?

Hi, Community!

Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production.

In a single server environment, it is rather easy to create a transaction consistent backup.

Simplified:
You find (or force a specific point in time with no open transactions.
Freeze your server, take a snapshot and you are done.

The following code snippet is a REGEX that validates characters that are not in English, as well as English characters. The class method "test" takes an email address and validates it based on this additional criteria:

Hey folks,

I am new to IRIS and cloud platforms. I've done the InterSystems IRIS Experience on the learning site and read a lot of the online documentation. What I am unable to figure out is which type of package or option you will use on the cloud provider.

AWS for example, has AWS EC2, Elastic Beanstalk and some other products geared towards Docker containers.
Azure has Kubernetes and some other options.

(Originally posted by @Eduard Lebedyuk on Intersystems CODE, 6/26/14) This code snippet determines the difference between two ObjectScript lists. The class method "test" runs the code, and its parameters are detailed in the comments:

The following code allows a user to view the audit settings of their instance. Run the code by running the class method "test":

Hi all. Today we are going to use k-means algorithm on the Iris Dataset.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, python 3.6.5.

Introduction

Hello,

I have imported my data with the following code (%DocDB).

set filename = "/home/student/Dokumente/convertcsv.json"

IF $SYSTEM.DocDB.Exists("Fitabase1") { 

SET db = ##class(%DocDB.Database).%GetDatabase("Fitabase1")

}

ELSE {

SET db = ##class(%DocDB.Database).%CreateDatabase("Fitabase1") 

}

set arr = ##class(%DynamicAbstractObject).%FromJSON(filename)

SET jstring = arr.%ToJSON()

//SET doccount = db.%Size()

DO db.%FromJSON(jstring) 

Now I have data sets like 

Hi, 
I have general question regarding the InterSystems Platform.
Which features does the platform have, that the other similar platforms doesn't have? 

InterSystems products (InterSystems IRIS, Caché and Ensemble) support AIX on Power 9 chips starting with:

Caché/Ensemble 2017.1.3

InterSystems IRIS 2018.1.1

Often InterSystems technology architect team is asked about recommended storage arrays or storage technologies.  To provide this information to a wider audience as reference, a new series is started to provide some of the results we have encountered with various storage technologies.  As a general recommendation, all-flash storage is highly recommended with all InterSystems products to provide the lowest latency and predictable IOPS capabilities.

The first in the series was the most recently tested Netapp AFF A300 storage array.  This is middle-tier type storage array with several higher models above it.  This specific A300 model is capable of supporting a minimal configuration of only a few drives to hundreds of drives per HA pair, and also capable of being clustered with multiple controller pairs for tens of PB's of disk capacity and hundreds of thousands of IOPS or higher.
