We are seeing more and more customers being lured with latest infrastructure technologies, particularly Composable Infrastructure. Coming with all sorts of data center consolidations and costs savings.

Question is: are there any concerns for HealthShare/TrakCare being run on these platforms or things to look out for? Anyone out there, already on these platforms?


To be more specific this is HPe Synergy with 480 Compute blades booting as bare metal.

Portal tip: System Mode

If you work with Portal on multiple instances of Caché, Ensemble or HealthShare you might find it useful to set the System Mode of the various instances, so as to give yourself a visual reminder of the role of the one you're currently working on.

Our small Seattle-based startup, Project Connect, is growing!  We’re seeking a Senior InterSystems Data Engineer with a strong background in InterSystems databases, processes, and tools.  In this role, amongst other responsibilities, you’ll perform development tasks to support installation, configuration, and customization of InterSystems HealthShare products, such as Unifed Care Record (UCR), Patient Index (PI), Access Gateways, Edge Gateways, etc. for development of a Health Information Exchange.

When creating pivots in DeepSee, there is the ability to group date dimensions by Day, Week, Month, Quarter, Year.  For some of our reporting the Week option is desired.  However the display looks like the image shown below.  Notice the "YYYYW##" formatting.

Is there any ability within DeepSee to modify the display of grouped week dates?  E.g. instead of 2020W14 it could be 03/30/2020-04/05-2020, or even just the start or end date, etc.

Return ACK from Process


We would need some help, please


First of all thanks for your time used reading this question

Also, thanks for your patience


We need to generate an ACK in a Process and return it to the Service to reply


We have currently written a code block with:

In this article, we’ll build a highly available IRIS configuration using Kubernetes Deployments with distributed persistent storage instead of the “traditional” IRIS mirror pair. This deployment would be able to tolerate infrastructure-related failures, such as node, storage and Availability Zone failures. The described approach greatly reduces the complexity of the deployment at the expense of slightly extended RTO.

When you have more than ten thousand users in your database, it becomes time-consuming and inconvenient to assign group access rights through the standard IRIS interface. In this artilce I want to introduce you an application to automate this process.

I’ll show you how to assign and change the role lists for the users, selecting them by context, and I will also show you how to expand this application’s functionality. you know how to apply your work as an administrator and developer to the new features of the well-proven apptools software complex. With the addition of an adminLTE template, you can now quickly and easily create interface interactions for any entity and many functional modules.
The goal while developing this toolkit is to write as little JavaScript as possible as well as transfer and implement all the dynamics as much as possible in the ObjectScript.

Hello everyone,

First, thanks in advance for your help :-)

I noticed that a query called directly in a method of a class of a business operation does not return the same result as if I apply the same query in the same Caché database from Squirrel !!! 

I don't understand why ??? 

Here is the query :

I'm trying to add a DR async member to a mirror but when I add this member I get this messages in the mirror monitor (on the DR member):

The message im talking about is the "missing Mirrored Databases report".

The only step I did was the " System Administration -> Configuration -> Mirror Settings -> Join as Async" an fill the blanks. Maybe Im skipping a step?

Is there a way to automatically transform Object Script arrays to Python lists?  This code results in a list of arrays

Iter0 =  dbnative.iterator("HS.Data.OIDMapD")
for subscript, value in Iter0.items():
    print(f"subscript={subscript}, value={value}")

Here is the result:

subscript=1, value=2.16.840.1.113883.3.86ISCInterSystems Corporation

I suppose it would be too hard to parse this into a list, I was just wondering if there was a function provided to make it convenient and proper.

Hi Developers! 
Let me share with you some exercises from a workshop about developing interoperability components in Java using PEX (Production EXtension).

You will find slides and step by step exercises about:

  • Understanding simple PEX components coded in Java.
  • Making some changes on them.

All built using containers, so you don't need to build a local Java environment.

Java Connection Strategy

We are planning to build a REST API with the Java Quarkus Framework.

  • There'll be a connection pool;
  • The DataSource instance will be automatically injected from the connection pool;
  • We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.

I believe that the Perl and Python bindings that exist on Cache / Ensemble do not exist on IRIS for Health 2020.1 ... is that correct?


Is there any similar documentation and samples (like below) , that show an example of how to run a basic Perl or Python script that connects with ODBC or whatever the recommended way?
