I'm trying to open a TCP connection to a remote system. The Caché command I'm using to open the connection is OPEN "|TCP|"_PORT:(IP::"PSE"):10 where PORT is a port number in the range 40000 to 40100 and IP is a standard IPv4 addess like 10.200.100.50 the connection appears to open because $TEST becomes 1. I'm then writing to the open port with USE "|TCP|"_PORT:(::"S") WRITE "some text",*-3 It's a windows system
I'm confused about the differences between a namespace and a database.
I understand that a database is a single IRIS.DATA file in a directory in the os hosting IRIS.
What is the difference between a namespace and a database?
Can I write data into a database without specifying a namespace?
If so how do I write to a particlar DB in objectscript?
Does a database have to be in a namespace?
Can a database be in more than one namespace?
Can a namespace have only one 'routine' database and only one 'data' database?
I have a database that is 2TB in size (from a LIVE system).
I would like to defragment it but I have some questions. I took a look at official documentation but it does not help.
Hi Community,
While writing an article yesterday, I realized I was so busy with people who came to the Developer Community table at the Tech Exchange that I forgot to take photos for you. Luckily, I realized the error of my ways and corrected my behavior accordingly 😉
So, let's look at what happened on Tuesday at the InterSystems Ready 2025! It began with a speech of Scott Gnau about the approach and architecture of InterSystems Data Platform and how it is different from all other DBMSs:
Is there a link we can use to invite other devs to ( so we can get credit for brining them in?)
Hi Guys,
I'm trying to use %Net.WebSocket.Client to collect data from a sever,
and part of that I needed to implement Two classes (SX3.Production.HTTP.AdvCredenials & SX3.Production.HTTP.AdvListener) as below for the purpose of Credentials & EventListener properties,
Class SX3.Production.HTTP.AdvCredenials Extends %Net.WebSocket.ICredentials
{
Method GetPassword() As %String
{
q ""
}
Method GetUsername() As %String
{
q ""
}
Method GetSSLConfiguration() As %String
{
q "MySSL"
}
}
Class SX3.Production.HTTP.AdvListener Extends %Net.WebSocket.IEventListener

I am attempting to follow the tutorial at Publishing Web Services Using Caché | Caché Web Services QuickStart Tutorial | Caché & Ensemble 2018.1.4 – 2018.1.11 to build a toy SOAP web-service using Cache but am running into what I suspect are permissions issues, or perhaps setting up the "plumbing" to get an incoming request to call the web-service methods.
Ensemble instance running on local laptop. Only the Ensemble private web-server installed on the machine (no IIS or Apache).
Hi Community,

Whats the significance of creating an Index with Data Keyword in Index
My HL7 message got "AR" (rejected ack code) and went to the suspended queue. I re-submitted it (without editing it) but forgot to write down the details before doing so. It got "AA" and everything works fine from there.
Now (the next day) I want to check with the downstream system why they returned "AR" initially. Is there a way to search for the original message the got an "AR", along with any returned error message please?
Thanks

Hello, This probably easy but I can't seem to figure it out. I need to send the first and last name of nurses to one segment target. How do I do this?

Hi all,
We're developing a medical appointment app that connects doctors' schedules to an appointment provider.
The provider is returning us the appointment in the following format:
Thu Jul 03 08:20:00 CEST 2025
It means, 03 july 2025 at 08:20:00 Central European Summer Time (UTC+2)
But we need the following format:
2025-07-03 08:20:00+02:00
Is there any option to convert zone time code (CEST) to a UTC+x ?
How to convert zone time code (CEST, CET, ET, EDT, etc..) in its zone time in UTC (UTC+2, UTC+1, UTC-5, etc..) ?
Best regards
Hi Community!
We have super awesome news for you! We're going to try to broadcast our Developer Ecosystem session from the InterSystems Ready 2025:

Previously, we trained our model using machine learning. However, the sample data we utilized was generated directly from insert statements.
Today, we will learn how to load this data straight from a file.
Hi Community!
I'm super excited to be your on-the-ground reporter for the biggest developer event of the year - InterSystems Ready 2025!
As you may know from previous years, our global summits are always exciting, exhilarating, and packed with valuable knowledge, innovative ideas, and exciting news from InterSystems. This year is no different. But let's not get ahead of ourselves and start from the beginning.
Pre-summit day was, as usual, filled with fun and educational experiences. Those who enjoy playing golf (I among them) got up at the crack of dawn to tee off before the sun got too high up. Here's our dream team in action:
@sween, @Mark Bolinsky, @Anzelem Sanyatwe, @Iryna Mykhailova

Hi community,
A few weeks ago I published an API accelerator call Memoria, Is a very simple way to minimize the time and network traffic to and end-point, I hope could be useful.

I have a class with a projection that creates some persistent classes (chunks) and a non-persistent "Daemon" class that I want to have running in the background, doing some processing. The daemon needs to look at the "chunk" classes, and I want it to be simple to start the daemon -- I am currently calling the daemon's start method at the end of the CreateProjection method. When I do this, I get a <CLASS DOES NOT EXIST> error from the daemon when it tries to query against one of the chunk tables. But, if I add a "HANG 5" at the beginning of the daemon start method, this runs fine. I am assuming

Hello, good morning, thank you so much for reading this question. ☺️🙂👍
We are developing a code to get information about our Production's items: services, processes and operations.
We know we can get various configurations of a given item: Category, Port, Enabled...
But we wonder how we could get the date time of the last mesage (most recent) received in an item.
To give a code snippet a small section of the code we have developed (and tested), it looks like:

This year I will go to the READY 2025 event (https://community.intersystems.com/post/registration-open-intersystems-ready-2025). See my plans:
60% of my topics are covered by developer sessions and the other 40% I will reach using 1:1 meetings, tech exchange and focus groups. I know, it is not possible stay at all sessions, but I will to try 30-40% of sessions. See it:
Hi everyone,
I'm preparing to move to a new PC soon and I'm trying to migrate the server connections I use in IRIS Studio to the new environment.
I’ve followed without success an old procedure I've found on a post on the community that involves exporting the registry key from:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Intersystems\Cache\Servers
But I’ve realized that this only includes the entries from the Server Manager and not the actual server connections used within IRIS Studio and shown within the "Server Connections" menu.
