Experience & feedback from online course "Hands-On with InterSystems API Manager for Developers" 

With my basic knowledge of Docker container and REST API, I would like to have my first try on using InterSystems API manager to take control of APIs and microservices. I have completed this online course using my local IRIS instance as host (Windows OS) and IAM running on a Linux VM (guest). 

Firstly, I will introduce InterSystems API Manager (IAM), then explain the steps for setting up my local environment and lastly walk through the course chapters.

Introduction

Hi, Community!

Are you using InterSystems Cloud Services? Take a tour of the central hub for managing your services and deployments:

InterSystems Cloud Services Portal Overview

How to create an ODBC connection on your native Windows laptop to IRIS running on a Windows VM on the same computer, test the connection, and pull data from IRIS into Excel.

Recently I learned that Excel can connect to external databases via ODBC. This includes basically any ODBC data source. Since IRIS speaks ODBC via the ODBC API, we can take advantage of the InterSystems ODBC Driver to establish an ODBC connection to IRIS on Windows that Excel can utilize.

Does InterSystems IRIS has a MEDIAN (or percentile) calculation in SQL?

Many programming languages use the try-and-catch construct to handle runtime errors gracefully. If the code within the try block encounters an error, it will throw an exception to the catch block, where the error handling occurs. Today we will dive into the ObjectScript implementation of this construct and discuss some ways to clean things up.

ObjectScript Implementation Basics

To get started, we will first look at the basic structure of the try/catch block:

try{
    //some code here
}
catch ex{
    //some error handling here
}

Does your team need a graphical view of your data? See how to use the InterSystems Reports Designer to create helpful visualizations:

Hi,

Is there a way to set the SettingSchedule  on a EnsLib.File.PassthroughService at 9:00 am to 9:30 am but only end of the month? 

When developing productions there are many places that we input endpoint information (IP/port) especially when there are dozens of operations going to the same environment. What later happens is that the IP changes and we have to then go into each operation and update the IP.

What is Journaling?

Journaling is a critical IRIS feature and a part of what makes IRIS a reliable database. While journaling is fundamental to IRIS, there are nuances, so I wrote this article to summarize (more briefly than our documentation which has all the details) what you need to know. I realize the irony of saying the 27 minute read is brief.

Hi Developers!

Recently we launched InterSystems Package Manager - ZPM. And one of the intentions of the ZPM is to let you package your solution and submit into the ZPM registry to make its deployment as simple as "install your-package" command.

To do that you need to introduce module.xml file into your repository which describes what is your InterSystems IRIS package consists of.

This article describes different parts of module.xml and will help you to craft your own.

I need to know if given package exists or not.

Currently found two solution - one doesn't work, another works but I don't like it.

Solution 1.

I started, of course, with %Dictionary package - it has PackageDefinition class after all.

However, %ExistsId returned 0 on packages that clearly do exist, so I went to %LoadData, it uses this macro to determine if the package exist:

#define PACKAGE(%package)             ^oddPKG($zcvt(%package,"u"))

And zw ^oddPKG showed the root cause - ^oddPKG global only contains data for packages with tables (or something along these lines).

Solution 2.

Recently I got into a situation where a user had some roles, which granted additional roles, and so on.

As I did not understand where a particular permission came from, I wrote this code which gets an initial set of roles and unwraps them recursively, accounting for any repeats.

Hi Community,

What are the advantages of using multiple namespaces for your code? Learn some of the benefits in this discussion with @Derek Robinson, Senior Online Course Developer, and @Scott Clark, Implementation Specialist:

Using Multiple Namespaces

Hi,

I'm new with writing Caché Objectscript so I need some assistance. I have XML which contains information like this:

<?xml version="1.0" encoding="UTF-8"?>
<session>
   <sessionId>124364</sessionId>
   <cabinet>demo</cabinet>
   <eventType>IN</eventType>
   <eventTime>20161006160154</eventTime>
   <login>test</login>
   <loginFirstName>test</loginFirstName>
   <loginLastName>test</loginLastName>
</session>

I have a class representing this object as follows:

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Size of CCDA Stream: 74152
vR4
{"resourceType":"Bundle","type":"transaction","entry":[]}

Here is my code: CCDtoFHIR.csp

Hi Developers!

This is the second post on the resources for Developers. This part is about Open Exchange

Using Open Exchange to Learn InterSystems

InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.

Hi Developers!

Recently I was asked, “How can a beginner in InterSystems technologies learn from InterSystems Developers community content to improve his developer skills”?

This is a really good question. It has several answers so I decided to write the post with the hope it could be useful for developers.

So! How to learn Intersystems Data Platforms(IRIS, IRIS for Health) from InterSystems Developers community content if you are a beginner?

Are you new to coding in InterSystems IRIS® data platform?

Hi,

I am using embeded python to utilize some pythonic library but i got a problem on my hand.
One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

Hey Community,

We have excellent news for you! We have prepared a new Instruqt course for you to sink your teeth into:

Hi, I need to make a prompt for a password and to not display what the user is typing in a CMD. I want to use the read command but i'm not sure if it is possible with it.

Hello dear developers,

I am currently doing an internship and learning about InterSystems IRIS and ObjectScript and have downloaded and installed the community version of IRIS.

I have not made any changes in the Management Portal.
In Visual Studio Code I have loaded the InterSystems ObjectScript Extension Pack.

If I now want to compile a file, VSC throws an error:
"ERROR #16006: Document name 'x.csp' is invalid"

The name of the file is "index.csp"
This error also appears when I try to compile other files.
I have noticed that the first 4 characters of the name are always missing.

Now, let’s say you can’t access the terminal or simply you just rather execute it from a web interface. In this article, I will show you how to execute terminal commands from a simple web page.

For example, in the image below you see how we execute $zv on a webpage:

This is mostly possible due to the XECUTE command in Caché ObjectSCript. This command takes a string as a parameter and tries to execute it. This is the command used from the webpage, to execute what is being passed from the left navigation menu.

Hi folks!

Recently I was in need to setup a local FHIR server using IRIS For Health and I think I found the easiest and simplest way ever.

Just run in terminal these two lines below :

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/irishealth-community

and

docker exec -it my-iris iris session iris -U "USER" '##class(%ZPM.PackageManager).Shell("install fhir-server")'

And you'll have FHIR server running locally at http://localhost:9092/fhir/r4.

That's it!

Is it possible to generate a random string in cache please advice thank you in advance
