#InterSystems IRIS

My name is Malcolm King and I’m an experienced IT Professional seeking full time employment.
I have 25 years of experience in the software development industry, with a wide variety of skills and knowledge. I have been involved in writing both front and back end code, along with interfacing to multiple systems, using multiple languages such as Cache Objectscript, C#, Java, Javascript and SQL.
I have experience with SOAP services and RESTful APIs as well as database design, implementation and administration.

Hello dear developers,

I am currently doing an internship and learning about InterSystems IRIS and ObjectScript and have downloaded and installed the community version of IRIS.

I have not made any changes in the Management Portal.
In Visual Studio Code I have loaded the InterSystems ObjectScript Extension Pack.

If I now want to compile a file, VSC throws an error:
"ERROR #16006: Document name 'x.csp' is invalid"

The name of the file is "index.csp"
This error also appears when I try to compile other files.
I have noticed that the first 4 characters of the name are always missing.

Hello

I would like to install the IRIS Community edition on Oracle Linux 9.0 for x86–64 but it is not proposed on the Community loading page. the only Linux versions proposed are Red Hat 8, Red Hat 9, SUSE 14, Ubuntu 20.04, Ubuntu 22.04.

As IRIS is supported on Oracle Linux 9.0 for x86–64, is it possible to get an Iris Oracle Linux 9.0 for x86–64 through the Community canal ?

Thanks 
 

Interacting with Users in the Terminal: A Guide to Using %Library.Prompt in IRIS

Have you ever wondered how commands like ^DATABASE engage users in the terminal? Or perhaps you're writing an automation routine and want ways to specify options directly from the terminal. Thankfully, the %Library.Prompt class in IRIS offers a straightforward way to do so!

String Input

For basic input, such as asking the user to provide a filepath or namespace, use the following code:

set status = ##class(%Library.Prompt).GetString("Input filepath:", .path)

InterSystems FAQ rubric

On Linux, use the following steps to delete an instance of InterSystems IRIS (hereinafter referred to as IRIS).

(1) Stop the IRIS instance you want to uninstall using iris stop 

# iris stop <instance name>

(2) Delete the instance information using the following command 

# iris delete <instance name>

(3) Delete the IRIS installation directory using the rm -r command 

# rm -r <install directory>

In addition to the installation directory, IRIS also uses (a) and (b) below.

Hi all,

Hello Everyone,

The Certification Team of InterSystems Learning Services is developing an InterSystems IRIS Developer Professional certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.

Note: This exam will replace the current InterSystems IRIS Core Solutions Developer Specialist exam when it is released. Please note from the target role description below that the focus of the new exam will be more on developer best practices and a lot less on the ObjectScript programming language.

How do I provide my input?

Hi Developers,

Watch this video to learn the different roles in OAuth 2.0, scopes, tokens, important authentication flows/grant types, and more:

⏯ OAuth 2.0 Fundamentals @ Global Summit 2023

Multi-tap or multi-press is the name given to the historic technique of writing SMS on the first mobile phones with a keyboard of 10-12 numeric keys. For example, to type LOL you need to press 5 three times, 6 three times and three times again. Your task is to write a function that takes a string as input and returns the repeated digits associated with each character according to the multi-tap system. Should consider letters from A to Z, doesn't distinguish between upper/lowercase characters. Numbers are allowed, and any punctuation should be ignored.

I am trying to troubleshoot an issue with LDAP and a specific user. Besides what is in the Audit Database is there another way to look to see the LDAP functionality that is being called and the response, like there is with OAuth and the ISCLOG? The Audit Log is returning a failure (Unexpected - /api/atelier login failure | InterSystems Developer Community) for this particular user, and I want to get proof that it might be something with the LDAP and not IRIS.

Thanks

Scott

Hi Devs!

Recently I was impressed by @Dan Pasco's article where he shares also how he uses terminal aliases. 

Terminal aliases is a very powerful tool for developers and sys admins if you often need to call some cumbersome terminal expressions and make it shorter and cleaner. Here is the documentation.
Yes! 

But what about Docker environments? What if you are fan of Docker dev environments but also want to keep using your favorite aliases with Docker as well?

Turned out it is very possible.

Hi Developers,

Get an overview of InterSystems IRIS in the different roles in OAuth 2.0 and the configuration menus for those roles. Watch practical demos of InterSystems IRIS in those roles and see how they connect back to OAuth 2.0 concepts:

Hi,

I'm having a few issues with keeping Ubuntu happy and stable, and it seems to be something at the OS level rather than within IRIS itself. My thought is to simply pare back the stuff that Ubuntu LTS runs by default, which will free up system resources (which really shouldn't be a problem, but it might help) and reduce the amount that can go wrong.

Are there any guides as to what can be safely disabled at boot time, or are required to be enabled?

Hi community.

Yes, I know that there is other question "VS Code - debugging doesn't work" that is the same issue, but my IRIS instance is not using IIS.

Some times ago, I could debug without problems, but after some updates of Visual Studio, I get the following error

Failed to start the debug session. Check that the Intersystems server's web server supports WebSockets

I've activated the WebSocket protocol in the server (Windows Server 2019) but it still doesn't work.

The IRIS instance is not using IIS, I think it is using the Apache by default.

Do I need to do anything in special?

The launch.

Hello Community,

SQL language remains the most practical way to retrieve information stored in a database.

The JSON format is very often used in data exchange.

It is therefore common to seek to obtain data in JSON format from SQL queries.

Below you will find simple examples that can help you meet this need using ObjectScript and Python code.

ObjectScript : using Dynamic SQL with %SQL.Statement

Introduction

This article attempt to summarize and update on the exchanges in this post. Please feel free to comment.
ObjectScript is based on MUMPS, a programming language dating back to 1966. At the time, and for quite a long period, memory and cpu resources were scarce, as was terminal screen space, and a very concise (and easily decodable) syntax was preferred (as, for example in C). Nowadays,  we no longer have the same memory and screen limitations,  and code readability and maintainability is far more important.

Hi folks!

Sometimes building an images via docker-compose.yml can take significant time.

And often after a minute or two of waiting it turns out that ports listed in docker-compose are busy and you need to start building process again with different ports or to turn down processes that took it.

Is there a way to check ports listed in docker-compose BEFORE starting the image baking process?

How do you deal with this problem?

Hi community.

I have an API that is deployed in my production (business service) and it calls to a business process to retrieve the information that is requested.

The problem that I have is that the calls are queued and it's creating a bottleneck 

The business process is taking more time than needed.

Is possible to configure the BP to process parallely the requests?

I'm thinking to increase the pool parameter, but I'm not sure if it's a good idea.

Best regards 

Looking at enabling long file paths (see https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-pat…) on some Windows machines - does anyone know offhand if IRIS plays well with this in all respects?

Hi, I was wondering if anyone already dealt with this issue:
"System has been suspended for over X seconds, exceeding the maximum duration specified. Allowing system activity to resume. Any ongoing backup has presumably failed. Next InterSystems IRIS backup must be a full one"

our backup system "Commvault" is automatic, how do you tell it once you get this message that the next backup should be full?

thanks,

Eyal

We are excited to announce a new part of InterSystems documentation that makes it easier to upgrade InterSystems IRIS® data platform, InterSystems IRIS® for Health™, or HealthShare® Health Connect. The Upgrade Impact Checklist at https://docs.intersystems.com/upgrade shows you all the things you need to consider – and only the things you need to consider – in an upgrade between any two versions.

A class (and routine) definition can sometimes differ from it's compiled state.
When such a thing occurs, a "+" sign will be shown in the tab of the file opened in Studio.

I would like to do the same check programmatically.

For routines, it's very simple : 

set##class%Routine

For classes, I could not find the equivalent. The only solution I found so far is to compare the compilation date and definition date :

%Dictionary.CompiledClass

Is there a better,  cleaner way ?
The main issue is that there is no proof that this is what Studio does. It probably use some more complex logic.

Hi.

How can I pass a large string to classmethod params (e.g. large pictures) without getting MAXSTRING error?

Is it possible to authenticate an xDBC (ODBC/JDBC) connection to InterSystems IRIS via (a 3rd party) OAuth server?

For REST APIs this is possible, but could this be achieved with OAuth? 

Out-of-the-box the ODBC/JDBC Drivers don't seem to have this option, but maybe some custom code could enable this? perhaps via Delegated Authentication and some OAuth classes customization, or some other way?

Has anyone done this already and can share how it was implemented, or someone with some guideline suggestions?

Do you ever spend an age entering criteria in the message viewer page, trying to find a message just to realise you're in the wrong instance of IRIS? 

Or get lost in a sea of message tabs struggling to spot that Visual Trace page your were JUST looking at?

Well, have you tried the IRIS WHIZ browser extension and its suite of tools designed to help you avoid such unpleasantness?

A customer contacted me with a problem trying to install Health Connect 2023.1 in a server with Red Hat 8 (no idea what 8.? it is). After review the logs the only error received are:

The umask configuration is right and the user has the permissions to create and manage directories in the server. Has anyone had the same problem? Do you ring a bell?

Lately my group has been seeing issues when signing in through the Management Portal or VS Code we are getting "Service Unavailable" errors returned to us. We recently migrated away from using the PWS to using Apache/InterSystems Web Gateway and using LDAP instead of Delegated Authentication. 

I have been on the hunt to find out where the problem might lie. When I run the "Test LDAP Authentication" from within the Management Portal, eventually I receive a response after getting a couple of timeouts while waiting for the response.

Hi community,

We have a developed a new version of a production, all the code is new and has changed BP. This application load information for some brands and stored in database.

The customer wants to implement the changes only for some brands because he wants to check for small brands before to implement for all brands.

My proposal is create a new namespace, with the new code, and disabled all load of brands except the brand that he wants to check.

I'm wondering what is the best way to clone the namespace.

Hello,

First of all thanks for your help reading and answering this question, and thanks for your time.

We have been investigating how to handle the following need:

Our client which has the system which reveices our ESB's responses needs a SOAP response as follows, where all the ACK is inside a top XML tag called <ACK>:

<?"1.0""UTF-8"<xmlns<<

We have developed the SOAP Web Service, however it always responds with an additional XML top level tag which is "<ProcesarPeticionResult>":

Hello,

How can I send a request via a SOCKS5 proxy in IRIS, using, for example, EnsLib.REST.Operation?

Background

I need to access APIs inside my corporate network, to which I don't have direct access from my home office. I've set up a SOCKS5 proxy via SSH on my host machine like this:

ssh -D 9999 server.corporate.com

I can then make requests with curl to the APIs I need:

curl -x socks5h://localhost:9999 https://api.corporate.com/api/some/endpoint

And I receive a response. Simple!

Also, inside the containerized IRIS, I can execute the request:

curl -x socks5h://host.docker.internal:9999 https://api.corporate.com/api/some/endpoint
