Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

Hello, developers!

In this article, we will focus on OAuth2, a protocol that is increasingly being used in combination with FHIR to perform authorization.

If you need create a upload REST API with IRIS is very simple. Do these procedures:

From Postman client you send a file

P.S.: It is a multipart form with a file type using "file" in the name. The request type is form/multipart. See the http request:

Wanted to share something I learned recently while working on a problem. We needed to add and change some Business Hosts in one of our edge productions.

In the past, we simply added the production class to CCR and then spreading it around. But there was a problem because different developers were working on different things, and we only wanted to include only the relevent production changes onto the CCR.

Here's a little piece of code that can help add new things to an existing production:

Last Friday November 17 suddenly ran into an error where ZPM would issue an error saying:

ERROR! Object open failed because 'Name' key value of 'xx' was not found

I googled but found no specific help. Step by step I was able to conclude that:

1. This is the error message for error 5770, also known as $$$KeyValueNotFoundOpen.

2. In objectscript, this error can be raised by calls to NameOpen, where 'Name' is the first quoted part in the error message.

Introduction

Accessing Amazon S3 (Simple Storage Service) buckets programmatically is a common requirement for many applications. However, setting up and managing AWS accounts is daunting and expensive, especially for small-scale projects or local development environments. In this article, we'll explore how to overcome this hurdle by using Localstack to simulate AWS services. Localstack mimics most AWS services, meaning one can develop and test applications without incurring any costs or relying on an internet connection, which can be incredibly useful for rapid development and debugging. We used ObjectScript with embedded Python to communicate with Intersystems IRIS and AWS simultaneously. Before beginning, ensure you have Python and Docker installed on your system. When Localstack is set up and running, the bucket can be created and used.

Hi Developers!

We're sure you want your ideas from the Ideas Portal to be implemented, so here are some steps you can take to attract attention to them.

Prompted by the words Rick didn't actually say to his pianist in Casablanca, I want to draw attention to the the "Resend" button at the top of the Ensemble Message Viewer.

It's pretty easy to use. Find the message or messages you want to resend, set the associated selection checkbox(es), then click the button.

Beginning in Caché 2013.1, InterSystems introduced Outlier Selectivity to improve query plan selection involving fields with one atypical value.

In this article, I hope to use an example 'Projects' table to demonstrate what Outlier Selectivity is, how it helps SQL performance and a few considerations for writing queries.

Our Standards

Examples of behavior that contributes to creating a positive environment include:

Every developer has made the mistake of accidentally leaving temporary debug code in place when they meant to remove it after debugging is complete. The great thing about writing in ObjectScript is that there is a way to make temporary code be truly temporary and automatically self-destruct! This can also be done in such a way that the code has no change of making it into your source control stream, which can be helpful as well.

Introduction

In the first article, a simple tutorial helped you to set up your FHIRaaS deployment.

Now, let's move forward and introduce a JS library to access the FHIR resource.

In the end, two examples of usage of this library will be presented, exploring the Appointment FHIR resource type.

SMART on FHIR JavaScript Library

FHIR is a REST API, so you can use any HTTP client in order to use it. But, it’s always a good idea to have help.
