I'm currently making some changes to legacy code and I've noticed that it uses "i $i("  all over the place. Testing in terminal seems like this does the same thing as "do $i()". Is there a difference between these two (and if not is there some interesting history around this)?

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

• The Operation uses class TNHS.SOAPclassExtra
• TNHS.SOAPclassExtra  Extends TNHS.SOAPclass
• TNHS.SOAPclass  Extends Ens.BusinessOperation
• Ens.BusinessOperation has a property ReplyCodeActions

Hi Community,

I am trying to read a JSON file and convert into HL7 message.Please find the example below

There is a Link Procedure Wizard option within the Management Portal (System > SQL >Wizards > Link Procedure) which I had reliability issues with so I decided to use this solution instead.

Problem

You need to query an external SQL database to use the response within a namespace. This guide is assuming that you already have a working stored procedure in SSMS although you could instead use a SQL block within the operation. Stored procedures in SSMS are preferred to maintain integrity, Embedded SQL can get very confusing if you have a complicated SQL statement.

In this example, I am

In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.

I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?

Thanks for your time,

In the Business Operation, how do we get to know which source is currently sending primary request if there are multiple requests coming at the same time?

In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.

With that being said, let's start the tutorial. Feel free to skip some steps if you're comfortable doing them alone.

Hi all,

For a requirement of the customer, we have a BS Rest api with a lot of methods, we need to get the IP of the caller, the method and what is the time that the API has taken to process.

I've found the event onPreDispatch where I can take the IP, ClassMethod, etc.. I'm using a global variable to save this information.

ClassMethod OnPreDispatch(pUrl As%String, pMethod As%String, ByRef pContinue As%Boolean) As%Status
{
	set^CallApi($CLASSNAME(),$JOB,"url") = pUrl
	set^CallApi($CLASSNAME(),$JOB,"method") = pMethod
	set^CallApi($CLASSNAME(),$JOB,"Start") = $HOROLOGset^CallApi($C

Introduction

Visual Studio Code (VS Code) is a free source code editor made by Microsoft for Windows, Linux, and macOS. It provides built-in support for JavaScript, TypeScript, and Node.js. You can add extensions to provide support for numerous other languages including ObjectScript.

The InterSystems extensions enable you to use VS Code to connect to an InterSystems IRIS server and develop code in ObjectScript. The Visual Studio Code Documentation is an excellent resource on VS Code, so it is a good idea to be familiar with it.

Hello,
First of all thanks for your time and help with this question.

We wonder how could we convert a String which represents an XML, to a class which extends from Ens.Response

Our context is a REST Operation, where we currently split the String with $PIECE and set each propertie as follows:

set codigo = $PIECE($PIECE(httpResponse,"<error><codigo>",2),"</codigo><descripcion>",1)
        set descripcion = $PIECE($PIECE(httpResponse,"<descripcion>",2),"</descripcion>",1)
        set codigoSERAM = $PIECE($PIECE(httpResponse,"</error><codigo>",2),"</codigo></resultado>",1)

Hi,

I am having an issue when I am publishing data to FHIR which is hosting in AWS. I am sending the data to the Cloud FHIR url but getting the below error.

Any idea how to resolve this issue? Any example to cretae FHIR repository using Object script?

:<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>404 Not Found</title> </head><body> <h1>Not Found</h1> <p>The requested URL was not found on this server.</p> </body></html>

I need to write test cases for Object script but need help for understanding the mock library in IRIS? Or need Suggestion for how to use mocking

Hello everyone,

I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.

Here is the context:

I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.

I created an initialization script for my database to be able to reset it at will, this script starts by emptying the database of this data, then initializes the basic data.

Hi Developers!

I want to share with you the approach you can use working with Unit Testing which I personally find very convenient and robust.

Will not talk much here about Unit Testing, we have documentation, enough good articles on the topic not only on the Internet but here on Developers Community too,  e.g. this one.

How can you manage the Unit Testing of your ZPM module?

This is pretty handy with ZPM. It has a special command "test" which runs all the tests you mentioned in the module. You can execute it as shown below:

zpm:USER>module-name test

And this command runs all the tests you mentioned in module.xml.

Let's see how it works.

Your may not realize it, but your InterSystems Login Account can be used to access a very wide array of InterSystems services to help you learn and use InterSystems IRIS and other InterSystems technologies more effectively.  Continue reading to learn more about how to unlock new technical knowledge and tools using your InterSystems Login account.  Also - after reading, please participate in the Poll at the bottom, so we can see how this article was useful to you!

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up. 

But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.

Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:

1. Start jobs.
2. Wait for all jobs to report success using $System.Event.WaitMsg().
3. Send Commit or Rollback using the $System.Event.Signal().

• The idea of this package is to compare the performance of columnar storage    inside IRIS without wrapping it to some foreign platform that is not my world   
• In addition, I do not want to measure network performance between 2 containers,     but inside a closed IRIS environment that I have fully under my control
• Even the use of SMP or some other browser-based presentation has some influence that I want to avoid.
• Measuring should be as close to the core as possible. So I flagged it NATIVE. Some people might feel it is ABORIGINAL.

How to use it

All tests are running in Namespace USER and

I had a question about using ZSTART, ZSTOP, and ZMIRROR.

• If we use them and it is not correct, does it mess up with any of the existing functionality?
• So, if I create a ZSTART with a simple command of starting the %JDBC Server will that mess up anything existing in the Startup sequence?
• Is ZSTART, ZSTOP, and ZMIRROR just an extension of the existing functionality, or does it alter how the built in functionality runs?
• Should we tread lightly in the use of them?

Intro

Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.

Hi Community,

Can anyone point me to the docs that show how to add automatic class documentation for the arguments used in a method call?   I can auto document the class, methods, properties etc. with the "///" but can't figure out how to get the nice argument documentation for the arguments used when calling a method.

Thanks in advance

I am sending an httpRequest from ObjectScript to a python server.   I am not receiving a response in OS
 
OS config On the client side

// Create an HTTP request object
    Set httpRequest = ##class(%Net.HttpRequest).%New()
    
    // Set the server URL
    Set httpRequest.Server = "http://127.0.0.1:8080"
    
    // Set content type to JSON
    Set httpRequest.ContentType = "application/json"

    // Clear any existing entity body"{""name"": ""Lowell Buschert"", ""dob"": ""1970-12-09"", ""address"": ""XXXXX""}"
    do httpRequest.EntityBody.Clear()
    //Set httpRequest.EntityBody = "{""name"": ""Lowell

I save / compile a class and instantly run a debug.  No issue

A few seconds later, try to run the same debug and get presented with either: 

1) Target Source is not compiled (Open launch json) dialog box

                                                    OR

2) The version of the file on the server is newer.

In the meantime I have made no edits to the VS Code window at all. 

If I pull a compare in response to #2 above, I am presented with a bunch of extent info built into the storage definition similar to the lines below.

Hello All

I'm not sure what the best practice is for this. I have a DTL for returning ORUs back to a hospital in a different time zone. They have requested that various timestamps have the time zone offset added to the HL7 format (%q%k, I think). First, I just wanted to be sure the system was aware it was DST. I was able to determine if DST is in effect like this:

<assign property='tzOffset' action='set' value='"-0500"' /><code><![CDATA[ SET dst=$SYSTEM.Util.IsDST()IF dst=1 {SET tzOffset = "-0400"}]]></code><assign property='target.{MSH:7}' action='set'

Our 3M Computer Assisted Coding system goes down on a regular basis for updates, the Applications folks like us to Disable the Business Operations when this happens and start them back up when they page the on-call person. The Business Operations have to be started in a sequence to guarantee that all the ADT being sent it processed before we start sending everything else.

Of course, I am looking for a way to automate this process, and before I go down writing a function to EnableConfigItem, then a for loop to check the ADT queue count, before enabling the other BO's, I was wondering if someone
