Hi,

I have to create to a web socket client, but I'm unable to read any data from the server, after flushing the buffer. I have no access to the server, only two examples for the client, one in java and the other one in php:

java example:

socket = new Socket("192.168.0.1", 2003);

DataOutputStream out = new DataOutputStream(socket.getOutputStream());

out.writeUTF("aPassword");

out.writeInt(websiteId);

out.flush();

DataInputStream in = new DataInputStream(socket.getInputStream());

int orderId = in.readInt();

For each instance of an XML-enabled class I want to control whether a property is projected as an empty element or not projected at all. With string properties, I can set the value as $c(0) for an empty element, or an empty string for no projection. But it looks like this isn't consistent for properties with type %Boolean or %Integer. With booleans $c(0) gets projected as "false". With integers $c(0) stays as a zero-width space in the XML output (which gives me a SAX parser error if I try to read it).

Is there a way to do this that works for all datatype properties?

Hello,

I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...

Is it possible to create a "lists/array/multidimensional 101" page for beginners? And, for instance, its interaction with $data, what it means to use "as list of something" or "as array of something", how to walk lists, how to add/remove elements, how to extract sublists etc?

Parquet files and InterSystems IRIS

In the world of Big Data, selecting the right file format is crucial for efficient data storage, processing, and analysis. With the massive amount of data generated every day, choosing the appropriate format can greatly impact the speed, cost, and accuracy of data processing tasks. There are several file formats available, each with its own set of advantages and disadvantages, making the decision of which one to use complex. Some of the popular Big Data file formats include CSV, JSON, Avro, ORC, and Parquet.

You might of seen or might of not seen my earlier post about Exporting a Production from 2018.1 to import it into 2021.1. I was able to get the export working, however I noticed in reviewing the data within the export, our previous Workday XML Schemas that we imported via XSD files were not in the export. When walking through the export process under Message Schema or vDoc Schema I could not find the missing XML Schema structures. Why aren't XML's part of the export process if they are used within the Production?

Simple problem:

  1. I leave a long-running command in terminal
  2. Switch to another task(s)
  3. Remember that I need to check on my command after a few hours

Is there any way to force terminal to the foreground after current command ends?

This is Windows with cterm/iristerm although Putty/Kitty solution would also be nice.

Having your Node.js Cake and Eating It Too

I've mentioned the QEWD project in this group before: it's a Node.js-based platform for web, Native and REST applications which tightly integrates with Cache. It uses a somewhat different philosophy to the use of Node.js than the norm, and I've now published an article that explains this approach and the unique benefits that arise as a result.

It turns out that, integrated via QEWD, Cache is an ideal bed-fellow for Node.js. QEWD makes the integration of Cache and Node.js exceptionally fast, simple and intuitive to use, but also extremely powerful.

I'm trying to create a SOAP service between two systems (one client and one server) to transfer files from the client to the server.

I'm reading through the documentation available at https://docs.intersystems.com/iris20223/csp/docbook/DocBook.UI.Page.cls?... but wanted to look at an actual example of code (preferably a small example for both systems).

If anyone has such an example or could create one, it would greatly help me understand how SOAP services work.

In this GitHub we gather information from a csv, use a DataTransformation to make it into a FHIR object and then, save that information to a FHIR server all that using only Python.

The objective is to show how easy it is to manipulate data into the output we want, here a FHIR Bundle, in the IRIS full Python framework.

How to become a time lord - Time travel

Time travel is like visiting Paris. You can't just read the guide, you have to throw yourself into it. Eat the food, use the wrong verbs, get double the charges, and end up kissing complete strangers.

The Doctor

We are now going to travel through time, that is, we are going to see future and past dates and how to calculate them in different formats. The TARDIS doesn't wait, take the controls and hold on tight.

Kinds of properties in IRIS

InterSystems IRIS has quite a few different kinds properties. Let’s put them in order so that they make better sense.

First of all, I would divide them into categories:

  • Atomic or simple properties (all those %String, %Integer, %Data and other system or user datatypes)
  • References to stored objects
  • Built-in objects
  • Streams (both binary and character)
  • Collections (which are divided into arrays and lists)
  • Relationships (one-many and parent-children)

Some of these kinds of properties are quite straightforward. For example, atomic properties:

Property Name As %Name;
Property DoB As %Date
Property Age As %Integer

Git behavior

We are going to start using Git within Cache.

One question came up - if the branch that you checked out does not have the class or mac file, what is the correct thing to do?

Should we delete from Cache or should we just keep it?

I'm leaning more towards deleting it because Cache should reflect what is in your work folder in git. But other team members are saying to keep it.

I defined the variables in Cache, as follows:

Property Content As% Stream.GlobalCharacter [Required, SqlColumnNumber = 3, SqlFieldName = B_Content];

And then use the SQL statement to add:

insert into table_name (B_Content) values ('very long string');

But the error:

Reference for the JSON Web Classes

Foreword

InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.

IRIS mirror - arbiter status

Hi,

I have a IRIS mirror set

. all running on SUSE Linux

. each on a separate server

consisting of

Primary

Backup

Arbiter

My arbiter is the ISCagent.

Question

=======

Is there a Linux command showing me the status of the ISCagent as arbiter?

The systemctl service command below shows if the service is running but not if it is acting correctly as an arbiter.

I'm looking for a command like iris list which you can run on the Primary or Backup
