Integrating frontend React applications with backend services like IRIS database via REST APIs can be a powerful way to build robust web applications. However, one common hurdle developers often encounter is the Cross-Origin Resource Sharing (CORS) issue, which can prevent the frontend from accessing resources on the backend due to security restrictions enforced by web browsers. In this article, we'll explore how to tackle CORS issues when integrating React web apps with IRIS backend services.

ODBC / JDBC data truncation

Hi, I hope this post helps.

The bottom line: MAXLEN is relevant mostly for odbc/jdbc connections and you need to specify an appropriate value within your tables (classes), otherwise the data might be truncated when you query it, or even fail when you try to insert data.

Long story:

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

InterSystems FAQ rubric

The meaning of each timeout value is as follows.

1. [Server response timeout]

If IRIS/Caché processing (routine or query execution) does not finish within this set time, the browser will return an error.

For example, if this value is 60 seconds and it takes 90 seconds to execute a routine/method/query, an error will occur.

2. [Queued request timeout]

IRIS Api Tester

Hello Community!!

I just upload my lastest application "IRIS Api Tester" to the Open Exchange.

It's a docker project with InterSystems IRIS + Newman that will allow you to test your Postman Collections in a quick and easy way..

It's ready to work out of the box, you just have to clone the repo: https://github.com/daniel-aguilar-garcia/irisapitester

Run the docker-compose file:

I am happy to share with you my first experience of using a docker container version of IRIS for Health to explore your interest in using or having a trial by taking the advantage of a docker container that is lightweight, and easy to deploy. This cookbook will go through the implementation steps using the GitHub repository called ENSDEMO written by Renan Lourenco.

Client Websockets based CSP

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

Hi Devs!

Recently I was impressed by @Daniel.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,

When wanting to use VS-Code for server-side editing.. - In VS-code I can right click on a server item (eg a class) to see a set of menu options including 'Server Source Control... ' and 'Server Command Menu...' at the bottom.

I noticed that these options are somewhat connected to my server-side source control hooks class that inherits from %Studio.SourceControl.Base, however, I am seeing different behavior between my custom subclass of this, and, the provided %Atelier.SourceControl subclass.

When using Related Cubes in InterSystems IRIS BI, cubes must be built in the proper order. The One side must be built before the Many side. This is because during build time for the Many side, it looks up the record on the One side and creates a link. If the referenced record is not found on the One side, a Missing Relationship build error is generated. The One side is going to be the independent side of the relationship, AKA the side of the relationship that is referenced by the Many side or the Dependent cube. For example: Patients contain a reference to their Doctor.

Webservice Response Changes


Hello,

I loaded a WSDL from a webservice into my project where executing it returns me a series of Orders related.

My problem is that the provider of this webservice sometimes adds new fields, which I don't even use, and from then on it starts giving Iris a bug, so I need to import the updated WSDL again so that it creates the new property that the provider added.

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

One of the most important tasks of dashboards is, on the one hand, to help you perceive data in an aggregated form, and, on the other hand, not to lose the depth of immersion in the data if you need this. One of the tools that help us achieve this result is drill down. It enables us to display several hierarchical levels of data, from aggregated to detailed.

Hi, Community!

Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production.

Join us at 07:00 UTC, April 24th for a webinar with a live demo "Git flows and Continuous Delivery" by @Eduard Lebedyuk

The language of the webinar is Russian.
