In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

These exceptions are different from %Status, so you can't directly/efficiently use the exception object with $SYSTEM.OBJ.DisplayError() or $SYSTEM.Status.DisplayError(). Instead, use the DisplayString() method to display the excepti

My usecase is sorting and removing duplicates and getting count from a file that has json messages as a individual rows.

I am currently planning to use pandas for this purpose as its really fast. Below are the steps i am following

1) call a python function (called function) from IRIS classmethod(calling function)

2) the call python function will read the json file in a dataframe

3) perform sorting, dup removal, count in the dataframe

4) convert the dataframe into iris stream

5) return back the stream to iris calling function class method

You may encounter errors during any point of program execution, and there are several ways to raise and handle these exceptions. In this article, we'll explore how exceptions are handled efficiently in IRIS.

One of the most commonly used return types is %Status, which is used by methods to indicate success or failure. Let's begin by discussing %Status values.

Working with %Status

The %Status return type is used to represent errors or success. Many system methods return %Status when an error occurs. You can create a similar structure for your application errors, or convert to %Status, even w

Question Serena Judge · Feb 6, 2025

I have an MDM interface with a DTL that takes OBX:5 and replaces "{\E\rtf" with "{\rtf" and "\X0A\" with nothing.  Most rtf's this works without a problem, some others, it corrupts the document.  

Code:

<assign value='..ReplaceStr(..ReplaceStr(source.{OBXgrp(k1).OBX:ObservationValue(1)},"{\E\rtf","{\rtf"),"\X0A\","")' property='target.{OBXgrp(k1).OBX:ObservationValue(1)}' disabled = '0' action='set' />

My question is - anyone know of any other "gotchas" that could possibly need to be replaced or something?

I have tried not doing the replace on anything, and the document shows up in view

Question Thomas Haig · Feb 4, 2025

At the moment we're creating multiple BPLs are using a router (or another BPL) to direct to these based on a unique key modulo the amount of BPLs available, e.g. if we have 3 BPLs created.
Message key = 1 mod 3 + 1 -> BPL02
Message key = 2 mod 3 + 1 -> BPL03
Message key = 3 mod 3 + 1 -> BPL01
FIFO only matters in that each messages for each key is processed in order.
What we were considering doing is increasing the pool size to 3 and programmatically creating a BPL on each thread that processes messages that would be directed to it, rather than having to create multiple BPLs into the production.

Hello,

When setting up a new web app in iris (iris is in a container) iris complains that a WSGI framework is not installed. I have installed python into the container as well as both flask and django via the python virtual environment (see second screenshot) and the python language server is running

Is this the wrong way to install flask? How do I get the container version to recoginize that flask is installed?

Why am I writting this?

Last year I made an article for starters on using embedded python. Later, it started a little discussion on how to return values with python and I found some interesting observations that are worth writing a little article. Also, hopefully I can reach more people by writing this.

Possible situations

There are two things you'll need to care about when returning a value with python. The first is the type you're trying to return and the second is where you're returning it. 

Let's remember our first lessons when we started coding: in python, when you define a functio

From the previous article, we identified some issues when working with JSON in SQL.

IRIS offers a dedicated feature for handling JSON documents, called DocDB.

InterSystems IRIS® data platform DocDB is a facility for storing and retrieving database data. It is compatible with, but separate from, traditional SQL table and field (class and property) data storage and retrieval. It is based on JSON (JavaScript Object Notation) which provides support for web-based data exchange. InterSystems IRIS provides support for developing DocDB databases and applications in REST and in ObjectScript, as well as providing SQL support for creating or querying DocDB data.

By its nature, InterSystems IRIS Document Database is a schema-less data structure. That means that each document has its own structure, which may differ from other documents in the same database. This has several benefits when compared with SQL, which requires a pre-defined data structure.

The word “document” is used here as a specific industry-wide technical term, as a dynamic data storage structure. “Document”, as used in DocDB, should not be confused with a text document, or with documentation.

Let's explore how DocDB can help store JSON in the database and integrate it into projects that rely solely on xDBC protocols.

Hi, Community!

In the previous article, we introduced the Streamlit web framework, a powerful tool that enables data scientists and machine learning engineers to build interactive web applications with minimal effort. First, we explored how to install Streamlit and run a basic Streamlit app. Then, we incorporated some of Streamlit's basic commands, e.g., adding titles, headers, markdown, and displaying such multimedia as images, audio, and videos.

Later, we covered Streamlit widgets, which allow users to interact with the app through buttons, sliders, checkboxes, and more. Additionally, we examined how to display progress bars and status messages and organize the app with sidebars and containers. We also highlighted data visualization, using charts and Matplotlib figures to present data interactively.

In this article, we will cover the following topics:

Hi,

I have Objectscript routine stored in an external Linux file which I've called /my/home/DisplayDB.int

This file does not include any Class definitions and is simply a set a Object script routines. I think this is called INT objectscript

The file looks like this:

set db=##class(Config.Databases).DatabasesByServer("",.dbList)
for i=1:1:$LENGTH(dbList,",") {
  set dbName= $PIECE(dbList,",",i)
  write dbName,!
}

How do I load and compile the Objectscript code?
Do $system.OBJ.Load("/my/home/DisplayDB.int", "ck")
How would I run the code?
do ^DisplayDB
Thanks in advance for any help

All pods are assigned a Quality of Service (QoS). These are 3 levels of priority pods are assigned within a node.

The levels are as following:

1) Guaranteed: High Priority

2) Burstable: Medium Priority

3) BestEffort: Low Priority

It is a way of telling the kubelet what your priorities are on a certain node if resources need to be reclaimed. This great GIF below by Anvesh Muppeda explains it.

If resources need to be freed, firstly pods with Best Effort QoS will be evicted, then those with Burstable, and finally those with Guaranteed. The idea is that hopefully by evicting the pods that ar
