Hi,

We have a mixture of legacy and new systems, and are grappling with the issue of moving documents between systems.

At the moment we are mostly using file drops and encoding metadata in filenames, but a new supplier (letter transcription) is going to provide a Hl7v2 feed sending MDM^T02 messages with PDF's of letters base64 encoded in the message itself.

We are thinking of asking all our suppliers to go with MDM (or ORU) for sending documents.

I'm interested in the pros and cons of the options; and if there are options I haven't thought of.

Hi guys,
I've setup an FTP passthrough service and operation to move two files from one SFTP server to another.
The files are moved and i can confirm with filezila that the whole operation went well.
However, i need to raise errors and send email if one the sftp servers is down for whatever reason, and if the trasnfer didn't go well.
I ticked the alert on error box for the passthrough BS and BO and the errors are indeed forwraded to an alert management system. I have real problems with the check on the SFTP servers.

Kong provides an open source configuration management tool (written in Go), called decK (which stands for declarative Kong)

Challenges of real-time AI/ML computations

We will start from the examples that we faced as Data Science practice at InterSystems:

• A “high-load” customer portal is integrated with an online recommendation system. The plan is to reconfigure promo campaigns at the level of the entire retail network (we will assume that instead of a “flat” promo campaign master there will be used a “segment-tactic” matrix). What will happen to the recommender mechanisms? What will happen to data feeds and updates into the recommender mechanisms (the volume of input data having increased 25000 times)? What will happen to recommendation rule generation setup (the need to reduce 1000 times the recommendation rule filtering threshold due to a thousandfold increase of the volume and “assortment” of the rules generated)?
• An equipment health monitoring system uses “manual” data sample feeds. Now it is connected to a SCADA system that transmits thousands of process parameter readings each second. What will happen to the monitoring system (will it be able to handle equipment health monitoring on a second-by-second basis)? What will happen once the input data receives a new bloc of several hundreds of columns with data sensor readings recently implemented in the SCADA system (will it be necessary, and for how long, to shut down the monitoring system to integrate the new sensor data in the analysis)?
• A complex of AI/ML mechanisms (recommendation, monitoring, forecasting) depend on each other’s results. How many man-hours will it take every month to adapt those AI/ML mechanisms’ functioning to changes in the input data? What is the overall “delay” in supporting business decision making by the AI/ML mechanisms (the refresh frequency of supporting information against the feed frequency of new input data)?

If you have ever issued the command ccontrol help to discover what ccontrol is capable of, perhaps you noticed this section:

Syntax:
ccontrol default
Description:
Display the name of the default Cache instance,
if one has been designated.

We are happy to present the bonuses page for the applications submitted to the InterSystems Developer Tools Contest 2025!

Hello all,

I'm a newcomer in ObjectScript and Ensemble and I would like to ask for any help.

I have a method which is called inside a BPL in order to create or append some data in a file by an operation. This is the current code:

If you define a Persistent Class / Table the class compiler generates for you an appropriate Storage definition.
A different option is to define a SQL mapping for an already existing Global storage. This has been excellently
explained already in a different series of articles. The Art of Mapping Globals to Classes 1 of 3

Apart from the database server itself, the standard bundle of the Caché DBMS includes DeepSee, a real-time business intelligence tool. DeepSee is the quickest and the simplest way of adding OLAP functionality to your Caché application.

Another standard component is an Audit subsystem with a web interface, which has the options for expanding with your own event types and an API for using in an application code.

Below is a small example of the joint use of these subsystems that answers the following questions: who did what and when in an information system?

I am calling a custom class in my transformation and brings back a base64, but my hl7 is doing a carriage return after about 70 characters of the base64. Any ideas how to work around this?

I want to do some logic based on what environment code is running in. I can't find a built-in function to retrieve this so I'd like to write a custom function. Does anyone know of a command that would get the current environment?

Hey community,

The InterSystems Developer Tools contest is over. Thank you all for participating in our exciting coding marathon!

And now it's time to announce the winners!

A storm of applause goes to these developers and their applications:

Taking advantage of the Quiniela ML application and as we indicated in the previous article, we are going to explain how we can perform a JWT authentication between our frontend developed in Angular and our backend developed in InterSystems IRIS.

I remind you of the architecture of our QuinielaML project:
