Can you get a boolean response in the same way you can with a Business component using  ##class(Ens.Director).IsItemEnabled(component).

Or even use this method for getting the adapter state?

How do I create recursive classmethod which stop all methods from running when condition are meet?

ClassMethod workpieceUnit(mainArticle As %String, article As %String) As %String
{
	
	&SQL(SELECT unit->unitCode INTO :unitCode FROM production_article.composition WHERE mainArticle = :mainArticle AND article = :article)
	
	IF SQLCODE = 0
	{
		W !, "Has Value"
		QUIT unitCode
	}
	ELSE
	{
		SET sql = "SELECT article, unit->unitCode,  production_article.composition_sqlArticleCode(article, type) AS articleCode FROM production_article.

Hi,

I want to know how to add a class to IRIS namespace 'USER' using terminal.

How do I do this?

I know you can add this class using Visual Studio Code with the Intersystems extension installed on my PC and connected to an IRIS instance.

Is it possible to do this with terminal? From this prompt:
BASETC:USER>

I have a class like in this example:

Class ObjectScript.RightTriangle
{

/// Compute area and hypotenuse of a right triangle
ClassMethod Main()
{
    write !, "Compute the area and hypotenuse of a right triangle",
          !, "given the lengths of its two sides."
    ....
}
}

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)
)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');

Hi, devs!

In ObjectScript I can refer to a class parameter as:

write ..#ParameterName

How do I do the same in Embedded Python?

Hey Developers!

Watch this video to get a brief overview of the InterSystems API Manager (IAM) and a deeper dive into new features of IAM 2.3 and 2.8:

⏯ API Management with InterSystems IRIS @ Global Summit 2022

Introduction

This article aims to give an introduction to what gRPC is and an example of how to play with the official Hello World using IRIS Embedded Python.

You can find all the code exposed here, in this project repo.

gRPC

The gRPC (gRPC remote procedure call) is an API architectural style based on the RPC protocol. The project was created by Google in 2015 and is licensed under Apache 2.0. Currently, the project is supported by the Cloud Native Computing Foundation (CNCF).

** Revised Feb-12, 2018

While this article is about InterSystems IRIS, it also applies to Caché, Ensemble, and HealthShare distributions.

Introduction

Memory is managed in pages.  The default page size is 4KB on Linux systems.  Red Hat Enterprise Linux 6, SUSE Linux Enterprise Server 11, and Oracle Linux 6 introduced a method to provide an increased page size in 2MB or 1GB sizes depending on system configuration know as HugePages.

At first HugePages required to be assigned at boot time, and if not managed or calculated appropriately could result in wasted resources.  As a result various Linux distributions introduced Transparent HugePages with the 2.6.38 kernel as enabled by default.  This was meant as a means to automate creating, managing, and using HugePages.  Prior kernel versions may have this feature as well however may not be marked as [always] and potentially set to [madvise].  

Transparent Huge Pages (THP) is a Linux memory management system that reduces the overhead of Translation Lookaside Buffer (TLB) lookups on machines with large amounts of memory by using larger memory pages.  However in current Linux releases THP can only map individual process heap and stack space.

Thank you to everyone who joined our User Group Session yesterday!

It was great showing off the new Deltanji Production Component driver that facilitates source control of interoperability productions, and we had some really insightful discussions as well.

If you missed out on the session and would like a copy of the recording, feel free to drop me a message. 

Hi,

I'm often required to copy the database from production to test.

This is to 'refresh' the database on test.

To achieve this I copy all required IRIS.DAT files from production to test.

The nodes are mirrored on production.

The nodes are not mirrored on test.

Each of the database files IRIS.DAT has a mirror attribute.

Is there a way of checking if the mirror attribute is set for the database file? eg. an objectScript program

Hello Community,

We're happy to announce that the InterSystems IRIS, IRIS for Health, HealthShare Health Connect, & InterSystems IRIS Studio 2022.2 is out now!

And to discuss all the new and enhanced features of it we'd like to invite you to our webinar What’s New in InterSystems IRIS 2022.2.

Is there a way for web application to set its session timeout value according to the user role or other criteria?

In this case, I have a custom production monitor page, and I want to set 5 minutes for most users but allow managers a longer time or those displaying pages on a monitor a longer time.

Hello community! I'm working on an internal innovation effort at InterSystems considering our documentation/resources around upgrades. As part of this, I'd love to have your answers to any/all of the following questions, either via comment or (if you prefer your answers to be more private) direct message.

Thanks in advance!

What InterSystems products + versions are you running? ($zv is ideal.)

What makes you decide to upgrade?

What are your blockers to upgrading?

What is your process for evaluating and planning a possible upgrade?

What documentation resources do you use?

How can I retrive the values present in the Category dropdown at the top of the production in code?

I use the following code to check the last modified date of file which is on a network shared folder (eg: "\\someserver\subfolder\foobar.txt")

set file = ##class(%File).%New(filePath)
set lastModifiedDate = file.DateModified //might hang up for a very long time 
set file = "" //close file

if the file is not available or does not exists, DateModified property return a negative value (which is fine). I use that property to quickly check if file has been modified and need to be imported.

Hi Community,

In this video, you will learn about exciting new ways to perform analytics using data in your HL7® FHIR® repository:

⏯ InterSystems IRIS FHIR SQL Builder: Sneak Peek @ Global Summit 2022

InterSystems is pleased to announce the 2022.2 release of InterSystems IRIS Data Platform, InterSystems IRIS for Health, HealthShare Health Connect, and InterSystems IRIS Studio are now Generally Available (GA).

2022.2 is a Continuous Delivery (CD) release. Many updates and enhancements have been added in 2022.2, in SQL management, cloud integration, Kafka and JMS adapters, the SQL Loader, and other areas. The new Columnar Storage has been released, but it stills an experimental feature.

Release Highlights

Platform Updates

InterSystems IRIS Data Platform 2022.

With IRIS 2021.1, we released a significant revision our SQL utilities API at %SYSTEM.SQL. Yes, that's a while ago now, but last week a customer asked a few questions about this and then @Tom Woodfin applied gentle mental pressure ;-) to make me describe the rationale of these changes in a little more detail on the Developer Community. So here we go!

How can get support on IRIS? 

Hello 

I have a class to render reports as  pdf. My problem that arabic characters in report replaced with ####. 

Please find my code below

#dim stream as %Stream.Object set report = $classmethod($piece(reportClass, ".cls"), "%New")
set report.RUID = RUID set %response.ContentType = "application/pdf"

set sc = report.GenerateReportToStream(.stream, 2) return:$$$ISERR(sc) sc
do stream.OutputToDevice()

return $$$OK

Your help is appreciated.

Hi Community,
Watch the recording of the Second Community Roundtable: "What is the best source control system for development with InterSystems IRIS?" 

Some great discussions have been started during this roundtable. We invite you to continue these discussions. in the comments to this post.

Tell us, which source control you use and why – in the comments to this post. 

Hi Community,

Please welcome the new video on InterSystems Developers YouTube:

⏯ Getting To Know FHIR - The Best Explanation of FHIR They've Ever Heard @ Global Summit 2022

A new release of ZPM has been published 0.5.0

New in this release

• Added support for Python's requirements.txt file
• Using tokens for publishing packages
• Fixed various issues

Python's requirements.txt

Now, if your project uses Python embedded and requires some Python's dependencies, you can add requirements.txt file to the project, as usual for any Python project, file have to be in the root of a project next to module.xml. And with load command or install command, ZPM will install dependencies from that file with using pip.

1. iris-dollar-list

Interpretor of $list for python named DollarList.

This interpretor was made because :

• I wanted to use $list in python.
• Embedded Python do not support $list.
• The native API version do not support embedded $list in $list.

This is a work in progress. For now, it only support embedded $list in $list, int and string.

WIP float,decimal,double

This module is available on Pypi :

pip3 install iris-dollar-list

It is compatible with embedded python and native api.

In Cache 2018, we were using a macro in a query that looked like this:

select $$GetExtraSQL^GetExtra('B',bddtl.odnumb,bddtl.odsnum,bddtl.oddsc1) as "Description", * from sqluser.bddtl

We could save that query as a view, and there was no problem with it.

In IRIS, if we put that query into SQL in the management portal, it still works, but if we save that query as a view, when we try to run a query on that view, we get a big error message:

ERROR #5540: SQLCODE: 400 Message: Process 604526 failed to compile Cached Query Class %sqlcq.R001.

This is the tenth in a series of releases that are part of the developer preview program for 2022.2. Future preview releases are expected to be updated biweekly and we will add features as they are ready. Please share your feedback through the Developer Community so we can build a better product together.

As usual,  CD releases come with classic installation packages for all supported platforms, as well as container images in Docker container format.  For a complete list, refer to the Supported Platforms document.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

MSH| ^~\&|||||20221014103828.043+0100||ACK^A03^ACK|1049|D|2.5.

Adding VSCode into your IRIS container

One of the easiest ways to setup repeatable development environments is to spin up containers for them. I find that when iterating quickly, it was very convenient to host a vscode instance within my development container. Thus, I have created a quick container script to add a browser-based vscode into an IRIS container. This should work for most 2021.1+ containers.

Hi Community, 
Let's meet virtually at our first Community Roundtable! This will be a 45-minfriendly discussion on a given topic: VSCode vs Studio. 
Imagine that we just gathered together to share our thoughts, experiences, tips, and tricks. If you want to discuss specific questions within a given topic - please share them in the comments.
