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.

Reports roadmap

We are about to embark on a development where we'll be taking HL7 messages and generating PDF reports from them. We are wanting to future proof our development efforts within the constraints of our currently deployed platform and future upgrade options. We are currently running on Ensemble 2018, though an upgrade to Iris is anticipated - at some indeterminate point in the future. We are aware of Zen Reports and InterSystems Reports (Logi) as technology options, but are also unclear on some details. A roadmap and guidance from those who've done this kind of thing before would be great!

Context

I have created a Business Operation (BO) named "Sender" that sends HTTP messages to an endpoint (for testing, I'm using Postman's Mock Servers).

Goal: I want to set up an automatic timeout mechanism so that if I don't receive a response from the server within 18 seconds, an alert is generated and the message is resent. This process should be repeated every 18 seconds, for a maximum of 90 seconds. If no response is received within 90 seconds, I would like to generate an error message. On the other hand, if a response is received, I want to stop the resending process and complete the operation by indicating successful reception.

Hi!

Currently, I'm working on a script using %SYS.Journal API.

My journal files are compressed, following the documentation the compression is zstd.

I tried to unzip a file with zstd tool, ex: 

apt-get update
apt-get install zstd

zstd -d 20230806.001z -o 20230806.001

20230806.001z        : 92.03%   (909312 => 836859 bytes, 20230806.001)

Unfortunately, the unzipped file is invalid:

Write ##class(%SYS.Journal.File).IsValidJournal("/usr/irissys/mgr/journal/20230806.001")

I'm setting up a web application as CSP/ZEN to host a React SPA. SPA's typically need to use a fallback page to deal with server requests based on the browser route, unless you use hash routing in the browser code. Our requirements prevent us from using hash routing, so we need to deal with 404's - redirecting/fallback them to index.html - a very common practice. I 'think' IRIS uses Apache under the hood, so I tried adding a .htaccess in the applications root directory - which did not work. I found that CSP has an Error class,

Hi All,

If I remember it correctly there is a functionality in IRIS to make this possible.

I've got two incoming Business Services of files from different sources.

BS1: An Ens.StreamContainer with some info and metadata which point to a specific file. Ens.StreamContainer will be send to a BP.

BS2: The files where the metadata points to. It's in the Ens.StreamContainer

But dependent on the flow the file could be later available on BS2. So I want the BPL to wait for the file to arrive at BS2.

We encountered difficulties while attempting to establish a JDBC connection to Intersystems using AZURE Databricks, resulting in an inability to retrieve data. The JDBC version utilized was intersystems-jdbc-3.3.1.jar. If anyone has successfully employed Databricks for establishing a connection, we would appreciate information regarding the libraries you used

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,

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

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.

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.

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:

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.

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.

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 ?
