TCP connection problems

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 have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation. Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation?

I am building a web application that uses JWT for authentication. I would like to pass the token in cookies instead of the Authorization header.
Is there a way to intercept the request and check the token from the cookies instead of the header? I tried overriding the OnPreDispatch() method and adding it to my dispatch class, but it seems like it never gets executed, as the response returns "Unauthorized" before reaching it.

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..) ?

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.

I have a segment within a Group (grp) that needs to be validated that it is populated within the message.

When you use a Foreach within a Business Rule how should you account for the counter in the group?

For example, Epic sends their MFN message in the following format.

MSH~MFI~[~{~MFE~STF~PRA~[~ZPR~]~[~ZLK~]~[~CER~]~[~ZMG~]~[~ZTF~]~[~ZGP~]~[~ZDD~]~}~]

Hello Community:

Do you want to know how to record yourself without looking like you're speaking from a cave? Are you one of those who say you ‘don't come off well on camera’?

Today I'm going to share with you some specific tips that I learned after several years of filming interviews for television and networks. I remind you that these are tips in case you are thinking of taking advantage of the Article Contest video bonus. However, they are tips that I'm sure you can use for presenting webinars, video calls and filming yourself in general.
