I'm trying to set up VS Code for ObjectScript using the instructions found here. I've got both Cache 2018.1.2.309.0 and IRIS 2020.1.0.215.0. When I try to connect to either one of them the connection fails, and I get a notification in the bottom right corner that says "Unexpected token < in JSON at position 0". I've checked the JSON settings file that VS Code uses, and they're fine and formatted properly. All of the settings I've entered are correct.

IRIS or Cache?

Hello all, 

I am in a bit of a situation where I could get your help please. 

I want to get certified with IRIS, but I also do see that there is an availability named Cache. 

Are they both the same or different? if different please explain it to me as how? 

Also what is the difference between IRIS, IRIS for Health, Deep Sea? Please explain to me.

Also what do you think I should get my self certified with? 

Please leave your comments below. 

Cheers.

At the heart of IRIS and Cache is a very interesting database architecture that we, at M/Gateway Developments, refer to as "Global Storage".  If you ever wanted to know more about the fundamentals and capabilities of this underlying database, you might want to read a major analysis we've put together:

IRIS in Astronomy

In this article we are going to show the results of the comparision between IRIS and Postgress when handling Astronomy data.

Introduction

Since the earliest days of human civilization we have been fascinated by the sky at night. There are so many stars! Everybody has dreamed about them and fantasized about life in other planets.

Hello,

I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.

If you could point me to any information, that'd be great. 

Thank you.

Hello community, 

I am in the process of building a Health Care Application named MediCloud and I was so excited to see that IRIS is one of a great choice that I can make for a database system. 

But, I am developing my system with ASP.NET Core Version 2.1. I did see that there is a way we could use .NET with IRIS using PEX (such a useful tip), is there a possibility I could do it ASP.NET Core as well.   

Or is it just limited to .Net for the time being? 

Cheers.

Hello everyone,

 

I have a doubt, its possible to use interface like C# using COS? 

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

Needing to know how to define a property that can either be sent in my response as 

"members": null,

or 

"members": [
                {
                    "dob": "1905-05-01",
                    "firstName": "BOB",
                    "middleName": "T",
                    "nameSuffix": "",
                    "genderCode": "M",
                    "lastName": "COLLINS",
                    "memberId": "123421741",

I have run into two annoyances when using VS Code for server-side editing of Objectscript and was wondering if anyone knows of any solutions or workarounds.

 

1. In .mac routine files, class names that aren't fully qualified (e.g. ##class(example) instead of ##class(Package.example)) fail to be understood, so the class will have a red squiggly underneath it and a problem that reads

"Class 'example' does not exist. InterSystems Language Server".

SSH for IRIS container

Why SSH ?

If you do not have direct access to the server that runs your IRIS Docker container
you still may require access to the container outside "iris session" or "WebTerminal".
With an SSH terminal (PuTTY, KiTTY,.. ) you get access inside Docker, and then, depending
on your needs you run "iris session iris" or display/manipulate files directly.

Note: 
This is not meant to be the default access for the average application user
but the emergency backdoor for System Management, Support, and Development.

Like hardware hosts, virtual hosts in public and private clouds can develop resource bottlenecks as workloads increase. If you are using and managing InterSystems IRIS instances deployed in public or private clouds, you may have encountered a situation in which addressing performance or other issues requires increasing the capacity of an instance's host (that is, vertically scaling).

Hello,

I have a quick question regarding TSTART, however not certain if there is an answer.

If I am inside the transaction and I loose connection - I always assumed that transaction would TROLLBACK, however it does not.

Is there anything special I need to set up with my TSTART, in order for this transaction to safely rollback?

*********

As example: Let's say I am inside the TSTART and setting up / altering some data and my VPN connection got disconnected.  I kind of expect all the data to be rolled back.  

Thank you,

Alex

External Language Server in 2021.1

Now that IRIS 2021.1 is available as a preview version, I would like to demonstrate a "new" feature. The Java Gateway has been around for a while now but in 2021.1 it has new skills. External Language Servers are available for Java, DotNet, and Python. Here is a quick - very quick - demo of using the External Java Server. Please don't focus solely on what this demo is doing but rather on what is happening in this demo. First, I acquire a gateway connection oref. This gateway connection is connected to the External Java Server - one of the External Language Servers.
