In various tests I used both and found no real reason to prefer the one or the other.
Eventually I missed some limits. At least I didn't hit any.
What is the general opinion?
Where to use the one or the other?

I ran into an interesting ObjectScript use case today with a general solution that I wanted to share.

Use case:

I have a JSON array (specifically, in my case, an array of issues from Jira) that I want to aggregate over a few fields - say, category, priority, and issue type. I then want to flatten the aggregates into a simple list with the total for each of the groups.

The Data Platforms team is very pleased to announce the 2021.2 release of InterSystems IRIS Data Platform, InterSystems IRIS for Health and HealthShare Health Connect, which are now Generally Available (GA) to our customers and partners.

Release Highlights

InterSystems IRIS Data Platform 2021.2 makes it even easier to develop, deploy and manage augmented applications and business processes that bridge data and application silos.

Hey Developers,

In the second part, you will learn how to build a FHIR Application with OAuth 2.0 and OKTA:

The InterSystems Iris Fhirserver running on a Raspberry Pi Raspberry running as a FHIRserver

Raspberry running as FHIRserver

About a year ago I wrote some articles about the installation of the HAPI FHIRserver on a   Raspberry Pi. At that time, I only knew the basics of the FHIR standard, little about the technology behind FHIR-servers and not much more about the Raspberry. By trying, failing, giving up and trying again I learned a lot.

Support is helping you troubleshoot a report. They want to reproduce a problem in their local system. Too bad they can't run your report, because the JDBC data source connection will fail. Or... is there a way?  

Hi all, 

any news about support of the IRIS platform in the DBeaver?  I only found this  https://github.com/dbeaver/dbeaver/issues/6289  Github issue. They are waiting for a new version of the JDBC driver. 

Thanks for the answer

Hey Developers,

We're pleased to invite you to the upcoming InterSystems webinar called "What's New in InterSystems IRIS 2022.1"!  

Date: Tuesday, May 24, 2022
Time: 11:00 AM EDT

In this webinar, we’ll highlight some of the new capabilities of InterSystems IRIS and InterSystems IRIS for Health, including:

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, the word anagram itself can be rearranged into nag a ram, also the word binary into brainy and the word adobe into abode. Wikipedia

You will receive two strings returning true if the two arguments given are anagrams of each other. As usual shortest solution wins.

Hey Community, 

This session provides more detail about the Smart Data Fabric announcement at #VSummit'21: 

⏯ Introducing the Smart Data Fabric

We are experience this with our own web app and even the demo/template here: intersystems-community/iris-fullstack-template: This template shows you how to build, test and deploy a simple full-stack application using InterSystems IRIS REST API (github.com)

When changes are made to CSS or HTML files, we can see the changes are saved to file in the Docker container by visiting the command line.  However, after refreshing, clearing cache, etc. the changes don't appear on the web application in the browser.  Viewing the source css in the browser, we see it's the old file.

Format Change in the ^mtemp and ^ERRORS Globals

InterSystems has several routines, methods and utilities that can create stack dumps.  Stack dumps are created in the ^mtemp(index) global by the %SYS.ProcessQuery:ExamStackByPid(.) classmethod as well as by some undocumented legacy entry points of the ^%STACK utility.  Stack dumps can also be created in the ^ERRORS(date,index) global by the ^%ETN trap routine, including additional entry points BACK^%ETN, LOG^%ETN, ^%ET and the Log() method of exception objects.

From  IRIS log, I found lots of following content

05/05/22-01:05:11:375 (16166) 0 [Generic.Event] ECP: Mirror Connection request from 'SM25SDLMIIRROR:LOCALHOST.LOCALDOMAIN:IRIS' (10.xxx.xxx.27:33040)

05/05/22-01:05:11:376 (16166) 1 [Generic.Event] ECP: Active server not defined, cannot redirect mirror connection

Could any one explain a little bit for me?

Hi Community,

The InterSystems Learning Website has many important iterative courses. So if you want to learn about InterSystems and start to work with InterSystems this is the path:

Overview:

• Resources and hands-on path for mastering source coding with the InterSystems IRIS: https://gettingstarted.intersystems.com
• Introduction to InterSystems Products and Technologies: https://learning.intersystems.com/course/view.php?id=1168&ssoPass=1

Fundamentals:

• InterSystems ObjectScript Basics: https://learning.intersystems.com/course/view.php?

This is a benchmark built in python and objectscript in InterSystems IRIS.

The objective is to compare the speed for sending back and forth a thousand request/message from a BP to a BO in python and in objectscript.

See https://github.com/LucasEnard/benchmark-python-objectscript for more information.

IMPORTANT : Here are the results of time in seconds, for sending 1000 messages back and forth from a bp to a bo using python, graph objectscript and objectscript.

String messages are composed of ten string variables.

Hi folks!

Sometimes we need to import data into InterSystems IRIS from CSV. It can be done e.g. via csvgen tool that generates a class and imports all the data into it.

But what if you already have your own class and want to import data from CSV into your existing table?

There are numerous ways to do that but you can use csvgen (or csvgen-ui) again! I prepared and and example and happy to share. Here we go!

Recently our team have been getting requests to pickup a large amount of data from API nightly (e.g. using ODATA to loop through pages) and placing that into MS SQL databases.

My question is, what is considered the best practice to get data from API and route to external SQL database WITHOUT persisting any messages/traces etc?

At the moment my thinking would be to write a service that triggers an action once a day to an EnsLib.HTTP.OutboundAdapter, then map the HTTP response into a linked table (via method to keep the operation clean that managed the gateway on the way in and out of the method).

What it the best method to call an object without ID but having RowID

SET task.Title = ##class(RESTAPI.TITLE).%OpenId(obj.Title)

I have tried using %OpenId() but it returns null

Any help would be grateful thank you.

I am sure I came across this in the past with Cache and just saw this again in IRIS.

When rebuilding or swapping a DAT file for a database it retains the Resource of the DAT file, not the Resource of the Database it is being used for.

For instance, if I have a local Database called APP with a resource %DB_APP and I want to refresh the data from another Database called TEST that has a Resource %DB_TEST I can just copy the DAT file from the TEST folder to the APP folder.

No Database settings are changed and it is all done with either IRIS down or the databases dismounted.

Hi.

Is it possible to set in XData mappings (or any other way) to serialize the property value as display value rather than value it self?

Hi

I have an a Ens.Request subclass (Invoice) that has a relationship property to another persistent class (InvoiceItems), with properties of its own and the inverse relationship defined referring back to Invoice. 

When building a DTL with these classes, the Relationship’s inverse relationship (Invoice, within InvoiceDetails) is displayed.   

Can this be hidden ? 

thanks

Given the following requirements about a WebSocket client:

• Start with the production automatically
• Try to re-establish a lost connection periodically
• Send an Ens.Request to another production item when a message is received from the WebSocket server

Where in the production does the WebSocket client need to live?

This year at Global Summit we will have several members of the InterSystems internal applications team (AppServices) on site to present topics of interest to developers.  There will be General Sessions that we teach on a number of topics related to tools we're launching to the OEX, knowledge gained based on migrating our Caché app portfolio to InterSystems IRIS, best practices for following OWASP Top 10 with ObjectScript, and a survey of the application landscape offering services to our customers and prospects.

Hi Community,

Imagine enabling your application to read text to your customer? This is now possible with the new IRIS feature, Embedded Python. With this new functionality IRIS can natively run any open source or commercial Python libraries natively. gTTS (https://pypi.org/project/gTTS/) is a free library that transforms text into audio using the Google Translate service.

How to

Just pass the text by parameter and gTTS returns an mp3 file with the text transformed into audio. That is, your application can play the audio of any text! See how to do it:
