What is an InterSystems Login Account?

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.

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?

Hi Everyone,

My name is Vignesh and I'm from Virtusa HR Team, we are hiring for a InterSystems Developer in US (Remote), If anyone is interested You can share your resumes avignesh@virtusa.com, also refer your friends.

Responsibilities:

-Building new and debugging and fixing existing HL7, CCD and custom data interfaces (JSON and XML) to internal and external destinations.

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.

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.

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.

Hi Community,

What is Defination of XData which we use using in Object script 

we are using XData  MessageMap and  XData DTL 

How can we use XData for different functionalities 

Thanks,
Joe

I have some code written in objectscript but need to trigger it from clinical viewer.   Someone does a search for a patient with a not found response which then triggers the code 

*** updated from a comment as original question may not have been clear**

To clarify my question this is the library property helper class Library property helper when you look at the documentation for computed from documentation here Computed documentation

ClassMethod FullNameComputation(cols As %Library.PropertyHelper) As %String
{
    return cols.getfield("FirstName")_" "_cols.getfield("LastName")
}
// ...

ClassMethod RecordsComputation(cols As %Library.PropertyHelper) As %Library.ListOfDataTypes
{
  Set rsTProp = ##class(%SQL.Statement).%ExecDirect(,

I recently realized it's been far too long since I talked about the latest features in the InterSystems ObjectScript Extension for Visual Studio Code. 

I'm pleased to announce version 2.12.1 of the ObjectScript extension, containing a number of enhancements that make a developer's life easier. Some highlights are described below, including the #1 requested feature from Global Summit -- XML import! 

As always, find the full list of modifications in the CHANGELOG, including many bug and vulnerability fixes.

“I have been waiting for thirty seconds for service. This is outrageous! I am leaving!”

“I am very sorry to hear that, sir. Perhaps, next time, you should make a reservation.”

If you heard that comment at your favorite restaurant, you would think the person saying it was being ridiculous. However, in the context of your API, it makes perfect sense. Just like your favorite eatery, your API has some regular patrons who, as you know, will be visiting one day or another. It would be great to be able to make a standing reservation for them as well.

It will involve a couple of IRIS fundamentals.

Hi Community,

Is there a way to call HL7 Data transformation directly from Business service without using Rule functionality in the production

In this scenario i need to call a data transformation in directly in business service and give the transformed message to Business operation 

Please share if you have any ideas to implement this.

Thanks,
Smythee

Hello everyone!
I need to transform a String, which is a numerical value, to an Integer.
The value gets returned in my Rest service as "testingID": "1234567", but I need it to be "testingID": 1234567

Thanks beforehand! Appreciate all the help I can get! :)

Does the GetValueAt method of an EnsLib.HL7.message object change the contents of the HL7 message?

We want to do two things, given an incoming HL7 message, in our production:

• transform the HL7 to XML, where the class TNHS.Utils.HL7toXML provides the same methods as, for example, EnsLib.HL7.Util.FormatSimpleXMLv2:
  

  set sc = message.OutputToLibraryStream(xmlstream,"","","TNHS.Utils.HL7toXML")

  
   

• extract a value from a particular field in the message: 
  

  Set ReportId = message.GetValueAt("PIDgrpgrp(1).ORCgrp(1).ORC:3.

Hi all,

I'm very new to this ecosystem so please bear with me:

I've startted learning online and have installed everything I need. I have VS code and I have most definitely installed the pack (3 packages) needed for working on it with ObjectScript. Even though this is the case I'm running into 2 problems:

1. when I type "class" I only get 4 option for auto complete. no "class with multiple inheritances" or anything of the sort. In fact, no Class at all, only ClassMethod. ClassResponse etc.

2.

Interacting with Users in the Terminal: A Guide to Using %Library.Prompt in IRIS

Have you ever wondered how commands like ^DATABASE engage users in the terminal? Or perhaps you're writing an automation routine and want ways to specify options directly from the terminal. Thankfully, the %Library.Prompt class in IRIS offers a straightforward way to do so!

String Input

For basic input, such as asking the user to provide a filepath or namespace, use the following code:

set status = ##class(%Library.Prompt).GetString("Input filepath:", .

Hi community.

Yes, I know that there is other question "VS Code - debugging doesn't work" that is the same issue, but my IRIS instance is not using IIS.

Some times ago, I could debug without problems, but after some updates of Visual Studio, I get the following error

Failed to start the debug session. Check that the Intersystems server's web server supports WebSockets

I've activated the WebSocket protocol in the server (Windows Server 2019) but it still doesn't work.

The IRIS instance is not using IIS, I think it is using the Apache by default.

Do I need to do anything in special?

The launch.

Hello Community,

SQL language remains the most practical way to retrieve information stored in a database.

The JSON format is very often used in data exchange.

It is therefore common to seek to obtain data in JSON format from SQL queries.

Below you will find simple examples that can help you meet this need using ObjectScript and Python code.

ObjectScript : using Dynamic SQL with %SQL.

Introduction

This article attempt to summarize and update on the exchanges in this post. Please feel free to comment.
ObjectScript is based on MUMPS, a programming language dating back to 1966. At the time, and for quite a long period, memory and cpu resources were scarce, as was terminal screen space, and a very concise (and easily decodable) syntax was preferred (as, for example in C). Nowadays,  we no longer have the same memory and screen limitations,  and code readability and maintainability is far more important.

Looking at enabling long file paths (see https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-pat…) on some Windows machines - does anyone know offhand if IRIS plays well with this in all respects?

Hello,

How can I send a request via a SOCKS5 proxy in IRIS, using, for example, EnsLib.REST.Operation?

Background

I need to access APIs inside my corporate network, to which I don't have direct access from my home office. I've set up a SOCKS5 proxy via SSH on my host machine like this:

ssh -D 9999 server.corporate.com

I can then make requests with curl to the APIs I need:

curl -x socks5h://localhost:9999 https://api.corporate.com/api/some/endpoint

And I receive a response. Simple!

Also, inside the containerized IRIS, I can execute the request:

curl -x socks5h://host.docker.internal:9999 https://api.

Hi Community!

Coding guidelines discussion. Consider you have For with one command in the cycle. Here are the options:

One

For i=1:1:1000 set ^Test(i)=""

Two

For i=1:1:1000 {
 set ^Test(i)=""
}

Same for the "If":

if a set b=a

or

if a {
 set b=a
}

Your choice? Or maybe even other options? 

In VS Code using the InterSystems ObjectScript extensions, I'd like the indentation applied to match that of IRIS Studio. Specifically for comments and dot syntax, I'd like pressing enter (carriage return) to preserve the current dot depth and same comment beginning.

In IRIS Studio after changing the indentation settings to custom using " \t.

Hello everyone!
I am wondering how I can retrieve multipart form-data from a request that is coming into my REST-service.
I am supposed to retrieve a string and a file. The file is being retrieved without issues, but the "testprofile" string is not being retrieved at all.
It just logs a an empty entry. 
The request that is sent to my REST-service has the Content-Type: multipart/form-data
Thanks beforehand for the help! :)

Down below is the code I use right now to retrieve the string and file from Form-data Rest HTTP-request to my service.

    set vProfile = %request.

Hello everyone!
I am receiving a HTTP multipart/form-data request into my rest service.
How can I read the values for each Key in the form?
The key "Profile" is sent to my service as a String data type.
The code I have below does not seem to work, where I try to read the Key profile in the form.

I appreciate all the help I can get! :)
