Cache Studio for IRIS 2024.3

Greetings,

As a long time Cache developer is there a way to get a copy of the Cache Studio that supports IRIS 2024.3? I do not have a WRC account? I need Studio just to experiment, not to build commercial software.

Thank you,

Everardo

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.

Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.

I would have to clear my cache files or browser history for it to reload and work.

Hey, community! 👋

We are a team of Stanford students applying technology to make sense of climate action. AI excites us because we know we can quickly analyze huge amounts of text.

As we require more reports on sustainability, such as responsibility reports and financial statements, it can be challenging to cut through the noise of aspirations and get to the real action: what are companies doing

That’s why we built a tool to match companies with climate actions scraped from company sustainability reports.

I am brand new to using AI. I downloaded some medical visit progress notes from my Patient Portal. I extracted text from PDF files. I found a YouTube video that showed how to extract metadata using an OpenAI query / prompt such as this one:

Trying to create a new SQL Storage map on existing cache Global in the following format - ^MYGLO("R",rec)=data where the 'data' is built using $zel. e.g. $zel(data,1)="p1", $zel(data,2)="p2" etc... and the ^MYGLO("R",123)=data.

I'm having 2 issues. First, using the SQL Storage map wizard, I cannot figure out how to convey data in $zel format in the "Delimiter" field.

Maximum license usage

Hello everyone

I have a question about the maximum number of active license users for CACHÉ.

When I run the command: Do $System.License.ShowCounts()

I get the following return:

1 Current active users
3 Maximum active users
0 CSP users currently active
1 Maximum active CSP users
0 CSP sessions currently in 'grace period'
1 Maximum CSP sessions in 'grace period'

Welcome, dear members of the Community!

In this article, we will present an example of a project implementing a FHIR-based solution. This project will be based on the national project (Spanish national project), known as ÚNICAS.

What is ÚNICAS?

In his own words:

A project whose objective is to create an ecosystem of partnerships to improve healthcare for pediatric patients with complex rare diseases (RMDs). This project is being implemented through the network within the National Health System (NHS) to improve the diagnosis and care of patients with rare diseases.

Transforms in COS over DTL

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!

At hackathons that InterSystems participated and I supported, many students were asking how all their teammates could use the same IRIS database that they spun up in a container. I suggested using ngrok to expose their localhost IRIS and realized we don't have documentation on that. Hence, I thought this would be great to let more people knwo about this powerful technique for enhancing collaboration during development and testing.

Hi ,

I have a scheduler task and an associated class that works.

Class Sample.Util.CreateTask Extends (%SYS.Task.Definition, %Persistent)
{

Parameter PROPERTYVALIDATION = 1;

Parameter TaskName = "Sample.Util.CreateTask";

Method OnTask() As %Status
{
// Perform the logic
}

}

Is there a way to Enable or Disable the above task "CreateTask()" from an external function/Method/class ?

The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

Hello everyone,

I'm looking for a practical project guide to help me gain hands-on experience with InterSystems Ensemble HL7. Ideally, this guide would walk through building a small project — something that covers key concepts like message routing, transformations, and interoperability.
