As an IT and cloud team manager with 18 years of experience with InterSystems technologies, I recently led our team in the transformation of our traditional on-premises ERP system to a cloud-based solution. We embarked on deploying InterSystems IRIS within a Kubernetes environment on AWS EKS, aiming to achieve a scalable, performant, and secure system. Central to this endeavor was the utilization of the AWS Application Load Balancer (ALB) as our ingress controller.

How can I print/view the count ?

Is there a way to use a property of the type %Persistent class in a  %ZEN.Component.page class?
Example:

// Data classClassExtends

Class

The problem is that when using it the described in the example.
The property can be set in a Method like this:

Method DoStuff() 

But when reading the property in an other Method the content of it is not set:

Is it generally possible to work like this?
Or have I overlooked a special handling?

You can use the WriteToConsoleLog method of the %SYS.System class to write any message to the console log.

The following is an example:

%SYSwrite##class

For details on the parameters that can be specified in the WriteToConsoleLog method, please refer to the following document:

Hello,

I tried to define Pool Size in System Default Settings, but it is not being used. I see I am not the first to try this without success:

Hi!
I have installed IRIS 2024.1 in RHEL 9.5, using the following 

sudo ISC_PACKAGE_INSTANCENAME="IRISTEST01""/iris"

I noticed some strange behaviour running $ZF, when the user appears to be "irisusr" but I can see the environment variables of "irisowner". I configured a RunLegacyTask scheduled task, with the following code

do $zf(-1, "id > /tmp/output.task.log && env >> /tmp/output.task.log")

it happens the same if I use $ZF(-100)

do $zf(-100, "/shell /stdout=""/tmp/output.task.log""", "id", "&&", "env")

and this is the content of the file

Hello interface engineers and app developers,     

Did you know that you can use Python in productions or integrations?

The production configuration user interface is low-code, but in many projects, you may reach a point where you need to write some code. As discussed in the Integration Architecture course, business processes are full of places for inserting code, specifically the BPL editor (for BPL business processes) and the DTL editor (for data transformations).

😯As of InterSystems IRIS 2025.1, both Python and InterSystems ObjectScript are supported in the BPL and DTL editors.

Hi!
I have question about MDX functionality in context of IRIS Analytics.

How does IRIS MDX distinct selection works? Is there any restruqtion when analyzing strings? Like special symbols or length?
Here is an example
I have this data:
 6 rows and 2 of them unique
Then we create data cube based on this model and examine it with Analyzer
 
Detailed listing
6 rows an ONE unique string. Which is obviously not true. 
This happed only with string with symbols in it
My task is to get the right amount of unique strings

Hi all.

I'm trying to create an indexed table with an vector field so I can search by the vector value.
I've been investigating and found that to get the vector value based on the text (token), use a Python method like the following:

The model all-MiniLM-L6-v2 is downloaded from https://ollama.com/library/all-minilm and installed into my Docker instance.

When I've tryed to test this métod (from Visual Studio), it throws the following error:

Hi, 

i'm with a trouble to take the api/monitor/alerts using prometheus.

i'm using prometheus 3.2.1 with IRIS 2022.1, the api metrics is working fine, but with the alerts, i'm receiving the following error:
 

and this is the answer in the request:

it apears the iris is not using the right way to answer the OpenMetrics the way Prometheus want.

Someone already see this?

Hi All,

  After doing IRIS/Ensemble etc for 20 years I've come across a company who have very odd view, especially about DTL's and routers.

  They have convinced themselves to use COS for transforms (including HL7) and for routers (and one of their 3rd party providers agree!)

  Their reasons are; efficiency, compatibility, flexibility, power and re-usability.

  Of course these reasons are wrong!

• Efficiency, difference between 1-2 lines compared to a DTL/XML going to 3-4 lines (This also assumes the COS code is well written)
• Compatibility, surely less with COS as its subject to developer style?

I was using VSCode to edit a DTL because it seemed easier to copy/paste code from parts of the DTL I was editing. I tried to add <sql> tag and code to call a SELECT statement, but when I compiled I got the following error...

ERROR <Ens>ErrInvalidDTL: Invalid DTL

  > ERROR #5490: Error running generator for method 'GetSourceDocType:osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'

ERROR: Ens.DataTransformDTL.cls(GetSourceDocType) of generated code compiling subclass 'osuwmc.Epic.MFN.DTL.EpicMFN949002Normalization'

Hi,

is there a way to starting & stopping Java Server programmatically ?

Thanks

InterSystems FAQ rubric

This can be done with TRY-CATCH:

 #dimAs

If you use ^%ETN, call it from the BACK entry (BACK^%ETN).

Introduction

This is a quickstart guide to IRIS for Linux systems administrators who need to be able to support the IRIS DB as well as other normal infrastructure tasks.

IRIS is a DB system from Intersystems. An IRIS DB can hold code (in the form of a Class) or data (in the form of Globals). IRIS DB are Linux files called IRIS.DAT.

Hi Guys,

For some reason %JavaServer is timing out so after a while I have to stop then start it again to get be able connect to the gateway?

Thanks

Once upon a time in Ensemble Management Portal the pool size of each component (Business Host) within the production was displayed in the Production Configuration page.

This information was very useful, especially when a production have tens or hundreds of components.

Now days the pool size is no longer displayed in the Production Configuration page and to get the pool size you need to click in each and every host in your production.
What if you have hundreds of business hosts and you need to check the pool size of each? It's a nightmare!

Perhaps this is an issue that has long been discussed somewhere. I have searched for it but still could not find the solution anywhere. In our environment, we send a container of SDA objects to UCR from HealthConnect. To populate the container we do a SQL query on a source system and then populate the appropriate SDA objects. Sometimes it happens that I want to do an update of a field and I want to empty the corresponding SDA field. In other words, send an empty string. The Alert.toTime field of the object in question is filled with the date '2022-11-29Z13:00:00'.

How do you collect stack info when debugging non-interactive jobs?

I cobbled this together today from the docs, but maybe there's something pre-built? LOG^%ETN()?

Hello there 🙋‍♂️,

I'm looking towards a functionality alike Python's difflib, but made with Intersystems products. I already know could embed Python code within IRIS but thought maybe there was a development already done for handling deltas, with a different approach or extra utils.

Even if I find such a library after comparing both might still go with difflib or any other more suitable. Intend to use it for a cross-environment checklist/check tool.

Please find below a sample of HTML rendering computed and made with difflib, with a few lines of code:

thanks ! best regards,
