#InterSystems IRIS for Health

I am working with InterSystems API Manager product and I'm trying to solve an authentication problem.  In our implementation, API Manager accepts basic authentication.  One of the endpoints accepts OAuth2.  The request coming into API Manager is FHIR and needs to have basic auth in the header.  The OAuth token is passed to API Manager as a parameter.  I want to send FHIR to the endpoint with a Bearer Token in the header instead of the basic auth that came into API Manager.  Has anyone used a transformation plug-in to solve a similar issue?

Hi Developers,

See how a FHIR implementation can be built in InterSystems IRIS for Health, leveraging both PEX and InterSystems Reports:

GA releases are now available for the 2020.4 version of InterSystems IRIS, InterSystems IRIS for Health and InterSystems IRIS Studio.

InterSystems IRIS Data Platform 2020.4 makes it even easier to develop, deploy and manage augmented applications and business processes that bridge data and application silos.

In this case I am trying to just send a simple error to the log in the event the try is not successful.  Have tried a few ideas I have found on the forum but none have worked as of yet.  

   try {
          // Write facility Details to cloned message
      set newPV139 = (FacilityNPI1 _"^" _FacilityName _"^" _ServFacility _"^" _FacilityTIN _"^" _FacilityAddressLine1 _"^" _FacilityCity _"^" _FacilityState _"^" _FacilityZip _"^" _CountyName _"^" _FacilityPhone)
      set newPV139insert = newrequest.SetValueAt(newPV139, "PV1:39(1)")
            } 
                 catch exception {

            }

Hello,

I am trying to figure out if we can extend a business process in IRIS. My Use Case is that I am developing RESTful Interfaces and my each REST Interface needs to go through certain processes before getting to the actual action.  

e.g. I have 2 REST Interfaces, GetPatient and GetEncounter. Both of these need to invoke "GetToken" Business Operation to go to the Authentication server to get an authentication token before they go ahead and hit the Business Operation to Get the data i.e. Patient or Encounter.

The InterSystems IRIS can be extended using Java or .NET components and its frameworks inside Object Script source code.

I created an application called OCR Service It built with Docker and installs Google Tesseract inside docker instance configured with english and portuguese dialects, but is possible install more than other 100 dialects. Google Tesseract can receive images and return text extracted from it, using OCR. The results are very good with the trained dialects. But you can train Tesseract to read car plates and any other textual patterns and load it to extract text.

In Studio you could open a class directly via it's name, without having to traverse the package tree with multiple clicks until arriving at the desired class.

You would Ctrl + O or (File -> Open) and be able to simply type in the class name, for example:

You press Enter, and viola - the class is opened.

How do you achieve this in VSCode?

Hi, everyone, 

We in InterSystems Learning Services are compiling and reviewing different non-InterSystems materials for learning various technologies. To this end, can I ask:

-What are your favorite learning resources (books, courses, etc) that have helped you with the development and implementation of the FHIR standard and why do you like them? 

Thanks, Jamie Kantor

Preview releases are now available for the 2020.4 version of InterSystems IRIS, IRIS for Health and IRIS Studio. As this is a preview release, we are eager to learn from your experiences with this new release ahead of its General Availability next month.

We are seeing performance issues in purging objects/tables that have parent-child relationships defined. Due to the number of child objects we're seeing very long duration to purge a single parent and all child tables. Is there a better way to do this and get a more performant purge task? I was thinking to purge the child tables individually first and then delete the parent is one way. Is there any other approach?

Hi,

is it possible to access a property defined as %List from sql? I´d like to search for a object containing a specific value in it´s %List defined property. Is there a predefined sql function for that within IRIS?

best regards,
Sebastian

AWS launched their first generation of Amazon EC2 A1 instances last year, powered by Arm-based AWS Graviton processors. At AWS re:Invent 2019, Amazon announced the second-generation AWS Graviton2 processors and associated Amazon EC2 M6g instance type, boasting up to 40% better price performance over current generation Intel Xeon based M5 instances.

The AWS Graviton2-based M6g instances are currently in preview, and InterSystems jumped on the opportunity to measure their performance with the InterSystems IRIS Data Platform.

March 23, 2021 – Alert: Potential Data Integrity Issue with Mirror Dejournaling

InterSystems has corrected a defect that can cause data inconsistency issues on non-primary mirror members in extremely rare circumstances. This defect affects all released versions of InterSystems products.

If the defect occurs, it happens silently during normal operation on a mirrored system. The result of this defect is that a mirror member fails to dejournal a subset of journal records, which then leads to data inconsistency across mirror members. This affects both failover and async members.

Introduction

InterSystems has recently completed a performance and scalability benchmark of IRIS for Health 2020.1, focusing on HL7 version 2 interoperability. This article describes the observed throughput for various workloads, and also provides general configuration and sizing guidelines for systems where IRIS for Health is used as an interoperability engine for HL7v2 messaging.

Hi Community!

⏯ Overview: Connecting Devices to InterSystems IRIS for Health

One of the REST APIs we need to call takes one of request parameter as a byte array. I am trying to create a message class and couldnt figure out which is equivalent type that corresponds to Byte[]. I need to read from a jpg file and then convert it to byte[] before i invoke this webservice. Appreciate if anyone can point me in the right direction. I can use %Stream.FileBinary class to store the jpg file after loading from a file. trying to figure out how to convert that to byte[].

Thank you,

Purpose

Most CloudFormation articles are Linux-based (no wonder), but there seems to be a demand for automation for Windows as well. Based on this original article by Anton, I implemented an example of deploying a mirror cluster to Windows servers using CloudFormation.I also added a simple walk through.
The complete source code can be found here.

Update: 2021 March 1 I added a way to connect to Windows shell by public key authentication via a bastion host as a one-liner.

My response definition is below.  I keep getting ERROR #9406: Unexpected format for value of field, physicianFirstName, using class base mapping. Any ideas would be helpful.

What do you think If I will say you, that very soon you will be able to connect to IRIS from the application written in Rust.

What is Rust

Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references. Rust achieves memory safety without garbage collection, and reference counting is optional. (c) Wikipedia

Most loved language for the last five years by the time of StackOverflow survey 2020.

What is possible right now.

The purpose of this article is to explain how the Interoperability menu works for system integration.

The left side of the figure is the window for accepting information sent from external systems.

There are various ways to receive information, such as monitoring the specified directory at regular intervals to read files, periodically querying the database, waiting for input, or directly calling and having it passed from applications in other systems.

This article is a continuation of this post.

In the previous article, how the Interoperability menu works for system integration was explained.

In this article, I would like to explain how to develop a system integration using the Interoperability menu.

To begin with, what kind of process do you want to create? While thinking about this, make the following content.

This article is a follow-up to this post.

In the previous article, [What is a Production?], we checked the production contents. We ran the sample code and checked the flowing messages' contents into the production on the Visual Trace page.

This article will review the concept and the definition of the messages used to send and receive data between components from the required development content for system integration.

• Production[ previous post ]
• Message
• Components
  • Business Services
  • Business Processes
  • Business Operations

Before creating a message, let's review the case study.

This article is a continuation of this post.

In the previous article, we reviewed how to create and define messages used to send and receive data between components.

In this article, I will explain how to create a business operation from the component creation methods.

• Production
• Message（previous article）
• Components
  • Business Services
  • Business Processes
  • Business Operations

We will quickly check the code by referring to the sample.。

This article is a continuation of this post.

In the previous article, we discussed business operations' creation from the components required for system integration.

In this article, you will learn how to create a business process that calls the two business operations you have defined in the sequence order.

• Production
• Message
• Components
  • Business Services
  • Business Processes
  • Business Operations (previous post)

The business process acts as the coordinator (command center) of the process.

This article is a continuation of this post.

In the previous article, we discussed the development of business processes, which are part of the components required for system integration and serve as a production coordinator.

This article will discuss creating a business service, which is the information input window for production.

• Production
• Message
• Components
  • Business services
  • Business processes（previous post）
  • Business operation

And finally, the last component of “Let's Use Interoperability!

Hello, developers!

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

In this part 1, we will start up the Docker container for IRIS for Health and Apache, configure the OAuth2 authorization server function on IRIS for Health, access it from the REST development tool Postman, and obtain an access token. Besides, in Part 2 and beyond, we will add FHIR repository functionality to IRIS for Health, add OAuth2 resource server configuration, and explain how to execute FHIR requests with access tokens from Postman.

I was having trouble with some dimension based calculated members defined in Analyzer.  They would work and then not work.   At one point I had two identical calculated measures, same code, same specification and one would work and one would not.  I was trying to set them up in "shared storage", that checkbox in the calculated member dialog that should allow the measures to be used across multiple pivots.
