InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

There is several classes that allow to create TCP/IP connections (eg: to connect to a service).

Example : %Net.FtpSession (port 21), %Net.HttpRequest (usually port 80 or 443)

AFAIK connection will stay open unless closed explicitly or if variable that hold the instance is garbage collected.

Is there a way to get a list of all active (open) TCP/IP connections IRIS is maintaining so far ?

Hi,

I try to initialize some properties of a %DynamicObject during his creation.

I Try to use InitialExpression this way :

Property refDate As %Date [InitialExpression = $piece($horolog,",",1)];

But it doesn't compile

I don't found if %DynamicObject can have a constructor to initialize properties by a calculated value, like other languages.

Hi,

Using Interoperability, I can't figure out how to create separate XML's files from a CSV-file using the GUI-features Record Maps/Complex Record Mapper -> Data Transformations. I'm familiar with reading/writing the files using File Service/Operation, but don't understand the processing-steps.
The preferred method by my colleagues is to do this without any Objectscript or Embedded Python coding, but if this can only be done by some coding that's fine as well.

See example below.
Any help is appreciated!

Kind regards,
Ties Voskamp

I asked the question in email and get answers from those colleagus.

Question:

I failed to change time zone on latest iris container(Ubuntu), because:

  • I am irisowner, no root password

  • There is no sudo command

I used to use below Dockfile setting to change time zone while creating a new docker image. However, those commands doesn’t work from non-root user.

Code Golf: Parenthesis

Our previous code golf ended with an overwhelming win, so now it's time for another one.
Parenthesis Hell is a Lisp-like esoteric programming language(esolang).
As a Lisp-like language, the code consists only of nested matched pairs of opened and closed parenthesis.
Your task is to write a method that receives a string of parenthesis and returns 1 if the order of the parenthesis is valid. For example, the string of parenthesis (())() is valid because it contains a matched pair of opened and closed parenthesis at each position. The string ()((()))) is not valid because it contains one unmatched parenthesis.

First time setting up a SSL/TLS connection, and I am running into issues when I call it from within a Business Operation. I used openssl to generate a RSA 4096  SHA512 key/csr request for our Active Directory Certificate Service to generate a Certificate Chain for me to use within RedHat. I was 
able to connect to our Web Service server using a generic request from terminal, however when I try it from our Business Operation I am running into issues.

I tested the SSL/TLS connection using the following commands from the terminal...

DEVCLIN>set request=##class(%Net.HttpRequest).%New()

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

InterSystems FAQ rubric

You can set individual error pages for the following Web Gateway error messages/system responses:

  • server error
  • server busy
  • server unavailable
  • server timeout
  • connection closed

Settings are made on the Web Gateway Management screen ([Management Portal] > [System Administration] > [Configuration] > [Web Gateway Management] > [Configuration] > [Default Parameters]).

In the Error Page section of the Default Parameters menu, set the filename of the html page to display or the URL to redirect to when an error occurs.

Hi Developers, I'm currently doing a demo about building a front end UI doing data analytics and setup a performance test with large data objects, therefore using "Populate Utility" could help me auto generate some sample data that I can play with.

Within this post I would like to share my experience of using Populate Utility, including using POPSPEC Parameter.

IRISPIP Cryptodome C++ Error

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

InterSystems IRIS currently limits classes to 999 properties.

But what to do if you need to store more data per object?

This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).

The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.

Class Documentation

I like to add documentation to the top of every class I write. Is there a way to modify or create a template that would automatically add the lines below to the top of the class? I primarily use Studio IDE but would like to be able to do this using VS Code as well.

Rule logic

In an HL7 Business rule I am trying to block ONLY ORM messages that have a PV1:3.4 of 105 or 205 and a OBR:4 value of EP22 or CATH01.

I created the logic below but it appears to be evaluating the two fields independently instead of combined?

Here is what I had.

Visual Studio Code, like Atelier, connects to IRIS through the Web Server and a web service, unlike Studio that connect to the SuperServer port.

What about the VS Code terminal? Does that open a shell with SSH or does it also use a web service?

In other words, does an IRIS developer using VS Code need direct access to the IRIS instance with SSH or the SuperServer port, in addition to the external or private web server to execute terminal commands?

Is that different with linux vs. Windows?
