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.
I have a sub class that calls a method in the parent class it is derived from.
However in the below code a <NO CURRENT OBJECT> error is thrown.
Set propertyValue = $PROPERTY($THIS,name)
Using the debugger I can see $THIS is returning the name of the subclass as it should and name is the correct property name (worth noting some properties are defined in the superclass not the subclass).
Why is this error ocouring and how can I fix it?
In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:
In this article, we would talk about building your own container and deploying it.
I was attempting to find a solution to grant clients anonymous access to certain API endpoints while securing others within my REST API. However, when defining a Web Application, you can only secure the entire application and not specific parts of it.
I scoured the community for answers but didn't find any exact solutions, except one recommendation to create two separate web applications, one secured and the other unsecured.However, in my opinion, this approach involves too much work and creates unnecessary maintenance overhead.

CentOS will no longer be a supported development platform as of the release of InterSystems IRIS 2023.3.
CentOS had been a supported development platform to give developers a free-to-use equivalent to Red Hat Enterprise Linux (RHEL) for IRIS development. As you're probably aware, Red Hat made significant changes to CentOS which moved it to being “upstream” of RHEL. This means it has bugs & features not yet included in RHEL, which can cause problems for developers building on the platform.
Developers using CentOS are encouraged to take advantage of Red Hat’s free

Hi Friends,
We have a requirement to read pdf text in ensemble object script code. As object script doesn't have direct solution , i tried to implement python code , but
iris 2020 , there is no support for python in object script.
so I have found one java utill using pdfbox api.
Now I have created jar and want to register into iris and want to make a call to mymethod to read pdf text.
please help me to way forward to achieve it.
java code:
============
package org.optimus.utils; import org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.text.PDFTextStripper; import java.io.File;
import os
# Get environment variables
db_host = os.getenv('DB_HOST')
db_port = os.getenv('DB_PORT')
db_namespace = os.getenv('DB_NAMESPACE')
db_username = os.getenv('DB_USERNAME')
db_password = os.getenv('DB_PASSWORD')
# Create a database connection
conn = irisnative.createConnection(db_host, db_port, db_namespace, db_username, db_password)
# Create an IRIS instance from this connection
iris_native = irisnative.createIris(conn)
status = iris_native.classMethodValue('%SYSTEM.OBJ', 'Load', 'Production.cls', 'ck')
if status == 1:
print("The Production.cls file was compiled successfully.")

Effective documentation is a cornerstone of software development, aiding in code comprehension, maintenance, and collaboration. By harnessing the power of Doxygen and the ObjectScript filter I've created, you can generate rich static documentation from your source code. This approach does not require a running IRIS instance and thus is a good choice in situations when access to IRIS is not possible. Static documentation may be provided to end-users as-is, together with the source code.
I searched through the community to find solutions targeting static documentation generation but

Hello Community,
I've enabled the JWT Authentication in my web application. I invoked the /login page to get the JWT and it creates an entry in %SYS.TokenAuth table. Is there any time span for the entries will rid out from the table automatically or It's a manual process? Where can I find the JWT signature private/public key

Will it hurt anything if I disable the user that installed IRIS, within IRIS? Does this cause a problem with background processes running or with the restart? I know the _Ensemble user is used to start/stop/restart objects within IRIS, just didn't see anything in the documentation about the user that installed IRIS.
Thanks

Saw the other day an article with the usage of the %ZEN package when working with JSON and decided to write an article describing a more modern approach. At some recent point, there was a big switch from using %ZEN.Auxiliary.* to dedicated JSON classes. This allowed to work with JSONs more organically.
Thus, at this point there are basically 3 main classes to work with JSON:
%Library.DynamicObject - provides a simple and efficient way to encapsulate and work with standard JSON documents. Also, there is a possibility instead of writing the usual code for creating an instance of a class likeset obj = ##class(%Library.DynamicObject).%New()it is possible to use the following syntax
set obj = {}%Library.DynamicArray - provides a simple yet efficient way to encapsulate and work with standard JSON arrays. With arrays you can use the same approach as with objects, meaning that yu can either create an instance of the classset array = ##class(%DynamicArray).%New()or you can do it by using brackets []
set array = []%JSON.Adaptor is a means for mapping ObjectScript objects (registered, serial or persistent) to JSON text or dynamic entities.Hi everyone,
My problem today is how to send an HTTP message to a web service deployed via Render and gunicorn.
Every time I try to contact the web service I get an error. Searching on the web, I've found this StackOverflow question that suggests the issue could be set off from a missing "/" character in the endpoint string.
I've tried in many ways, both including and excluding the final slash character, but I always get an error:
https://<renderProjectName>.onrender.com), the message is successfully sent but I get the error HTTP/1.1 307I am trying to move us to Securing the Management Portal using Apache and the Web Gateway.
Our Development environment/namespace only has 1 server, but both Test and Production have failover/DR mirroring containing 3 servers for Test, and 3 additional servers for Production.
In Test and Production, the mirroring is setup using an Arbiter and the VIP address is controlled at the Hardware level.
Could you please help anyone how to import Python package in %SYSTEM package and to use python methods to write in object script class?
I used the following link to install the Python but I can't see the Python package in %SYSTEM package and my program throwing the Class Does not exist error?

Hello,
I have a problem attempting to store a base 64 encode stream into the OBX:5 field of a HL7 message, by using the StoreFieldStreamBase64 method.
I'm using a transformer to input the contents of a pdf within a stream container (Ens.StreamContainer). The output is a HL7 message (EnsLib.HL7.Message 2.5:ORU_R01).
The transformer is being used in a business process.
This is the code used in the transformer to encode the stream to base 64:
Try {
Set pdfStreamObj = source.StreamGet()
} Catch {
Quit
}
//Set PDF stream object into OBX:5

Hello community, I need to solve a complex but trivial issue.
Given:
Two tables "Comment" and "Post". Each one contains an "Author" field, which is essentially a user ID. In these tables, each user ID represents an author. The goal is to count all participants together and then group them by month, language, and other metrics.
The question is how to do this within the IRIS ecosystem. Is it even possible to take two tables, get distinct data from them and then combine into one cube?
Hello Community,
I have couple of question about the DynamicSQL.
1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.
2. What is the reason behind for a stored query prepared using %PrepareClassQuery() you must use the %Get("fieldname") method.
Class Samples.DB.NewClass1 Extends%Persistent
{
Property Address As NewClass3;ClassMethod TestQuery()
{
set statement = ##class(%SQL.Statement).%New()
set statement.%ObjWe are back to %SYS once again! Since we covered managing users and resources in the last two articles, we can finally move on to roles. As you may have guessed, there are a lot of methods of managing them that you have already seen in our previous writings. However, we can still encounter key differences in this particular class.
Before we begin, bear in mind that this is another class that should not be manipulated through direct SQL access.In newer versions of IRIS, you will find a NoSQL trigger that will prevent you from doing that anyway.
ObjectScript allows you to pass any number of arguments using arrays. Do it by adding ... after the argument name.
An example is as follows. In the example statement, the argument information is set in a global variable (a variable stored in the database) so that it can be easily checked after the method is executed.
Class TEST.ARGTEST1 Extends%RegisteredObject
{
ClassMethod NewMethod1(Arg... As %String) As %Boolean
{
kill ^a
merge ^a = Arg
}
}The result of running it in the terminal is as follows.
USER>DO##class(TEST.ARGTEST1).NewMethod1(1,2,3,4,5)
USER>ZWRITEHello,
