Hi - Recently I have been investigating an annoying situation whilst editing ObjectScript classes or routines in VSCode.

What was happening to me was, as I was typing in lines of code into my class (for example, adding a new Method, or changing the Class signature, or a block of code), this would quickly get syntax checked, re-formatted, and compiled - inevitably, (since I would be mid-way through my typing), this would generate compilation errors.

VIP in Azure

If you're running IRIS in a mirrored configuration for HA in Azure, the question of providing a Mirror VIP (Virtual IP) becomes relevant. Virtual IP offers a way for downstream systems to interact with IRIS using one IP address. Even when a failover happens, downstream systems can reconnect to the same IP address and continue working.

The main issue, when deploying to Azure, is that an IRIS VIP has a requirement of IRIS being essentially a network admin, per the docs.

To get HA, IRIS mirror members must be deployed to different availability zones in one subnet (which is possible in Azure as subnets can span several zones). One of the solutions might be load balancers, but they, of course, cost extra, and you need to administrate them.

In this article, I would like to provide a way to configure a Mirror VIP without the using Load Balancers suggested in most other Azure reference architectures.

As an example of an application on Java working with Hibernate dialect for IRIS, wanted to use RealWorld application, and found realization for Quarkus. RealWorld application is an example of an application close to some real one, with already prepared tests for the backend. Most of the examples of realizations can be found here

RealWorld Example App

The RealWorld example application is often referred to as the "Wikipedia for building full-stack applications." It serves as a standardized prototype that developers can use to create applications using various programming languages and frameworks. The application provides a real-world use case by mimicking a blogging platform, complete with features like user authentication, profile management, article posting, and comments. With a comprehensive set of specifications, including ready-made backend API documentation and frontend designs, it allows developers to see how the same functional requirements are implemented across different technology stacks. The RealWorld example is widely used as a learning tool and a benchmark for comparing various technologies.

Quarkus

Quarkus is an open-source, Kubernetes-native Java framework tailored for the GraalVM and HotSpot. Created with the aim to enhance the modern cloud-native environment, it significantly reduces the footprint and startup time of Java applications. Quarkus is known for its "container-first" philosophy, allowing developers to build lightweight, high-performing applications with a focus on microservices architecture. This flexibility has made it a popular choice for organizations looking to transition into serverless or cloud-based platforms, combining both imperative and reactive programming models. Whether it's a traditional web application or a complex system of microservices, Quarkus provides a robust platform for building scalable and maintainable software.

With the advent of Embedded Python, a myriad of use cases are now possible from within IRIS directly using Python libraries for more complex operations. One such operation is the use of natural language processing tools such as textual similarity comparison.

Still working on my first External REST API call, and I am struggling to find the exact answer I am looking for... I get a JSON response from my API call but I am not quite sure how to dynamically get the JSON response into the Ens.Response Object with its lists of Arrays that I have defined.

set tSC = ..Adapter.SendFormDataArray(.tHTTPResposne,"POST",tHTTPRequest,,,tURL)

Are you preparing to use VS code for the first time? Just make sure you have enough privileges.

Have you defined your Iris server in your VS Code settings, and still get the following error?

VS Code accesses Iris/HealthConnect using the web application /api/atelier. If you do not have permission (i.e. you are using an LDAP user to connect and the web application is not configured to support LDAP), this is the reason why you couldn't connect.

Hi everyone,

I'm working on a Business Operation whit an HTTP Outbound Adapter and I would like to know if is possible to adjust the FailureTimeout value based on the incoming message type. For example, I would like to have a FailureTimeout of 60 seconds for the standard operations and a FailureTimeout of -1 (wait forever) for few special operations that absolutely need a response.

Can we dynamically modify the FailureTimeout through code, based on either the incoming message type or a specified parameter?n the incoming message type or depending by a parameter?

IRIS 2024.1 Preview - New Feature

There is an interesting new feature in the recently announced 2024.1 preview, JSON_TABLE. JSON_TABLE is one of a family of functions introduced by the 2016 version of the SQL Standard (ISO Standard, published in early 2017). It allows for JSON values to be mapped to columns and queried using SQL. JSON_TABLE is valid in the FROM clause of some SQL statements.

The syntax of JSON_TABLE is quite large, allowing for exceptional conditions where the provided JSON values don't match expectations, nested structures and so on.

Hello, I tried to convert HL7 message to JSON in a business process and I got errors. Has anybody converted HL7 to JSON? Are certain characters not allowed in JSON?

I just tried to set a property to quote request.RAWContent and quote. I will try to put example in GitHub and share here later.

I am using the event logger from CSP gateway with level "v9r" enabled, in order to dump the raw content of some HTTP requests.

I would like to decode the body response data, when it's in binary form. AFAIK the event logger will convert characters outside the 32-127 range (EBCDIC) to the "\xff" notation (where ff is a hexadecimal value). Here is an example :

Good morning
Thank you for taking the time to read this issue.

In interoperability environments, in what way is it recommended to monitor and detect changes in Web Production components between environments, for example between Pre-Production and Production, or even between alternate Nodes of Production Mirrors?

We ask this question in order to find out what are the best practices, and what is the most methodical, systematic, simple, robust and secure way to perform this monitoring.

We have a service account that is running queries to pull some data. It has read only access to the tables, but, unfortunately, the tool is starting a transaction before it reads the database. The query takes more than 20 minutes (21 - 23 minutes), so we're getting the console message that the transaction is open longer than 20 mins. Is there a way to prevent a user/service account from being able to start a transaction since it only has read access to all of the tables in the database?

IKO & The Compatibility Version Gotcha

With the world (as well as our own technology) moving to the cloud at such a fast pace it is easy (at least for myself) to get caught up in the little details. One thing I, and some clients of ours, had run into a couple of times was the necessity to specify the version of the images one plans to use with the IKO.

Hi community,

I have an incorrect InterSystems Server Credentials password stored by the Workstation Keychain in VS Code. VS Code is trying to use this incorrect stored credential to access the server and does not prompt or allow me to input a different password. I do not see any settings associated with the Keychain or resetting those credentials. Does anyone know of the process to delete or replace a stored password here?

Thanks!

Hannah
