#API

9

Application Programming Interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components.

We recently moved from using the Private Web Server, to using an Apache/Web Gateway setup and moved towards using the built in LDAP functionality within IRIS. Since then, we have 1 user that uses VSCode (/api/atelier) heavily that continues to have issues signing into IRIS through VS Code and the /api/atelier extension.

I am trying to troubleshoot two issues..

1. Scope and Objective:

Recently we supported a few NHS cases that required TIE (Trust Integration Engine) integration with the PKB service. Hence this article is meant to be a 10-minute quick guide to describe a demo solution (simple configurations and end-2-end implementation steps) for Health Connect (Ensemble) Integration with PKB (Patient-Knows-Best) service.

Introduction

Nowadays, there is a lot of applications that are using Open Authorization framework (OAuth) to access resources from all kinds of services in a secure, reliable and efficient manner. InterSystems IRIS is already compatible with OAuth 2.0 framework, in fact, there is a great article in the community regarding OAuth 2.0 and InterSystems IRIS in the following link here.

Load a ML model into InterSystems IRIS

Hi all. Today we are going to upload a ML model into IRIS Manager and test it.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, Python 3.6.5.

Introduction

These days many available different tools for Data Mining enable you to develop predictive models and analyze the data you have with unprecedented ease. InterSystems IRIS Data Platform provide a stable foundation for your big data and fast data applications, providing interoperability with modern DataMining tools.

REST Data Limit

I'm experimenting with sending large amounts of data in a POST payload to be stored as a stream. However I've noticed that no matter how many characters are in the message, Cache only gets about 32k of them, cutting off the rest. Conversely as expected it can only send about 32k worth of characters in a payload.

Before I get creative, is there a REST message size limit that can be changed? Or is there something else going on here?

Thank you!

Hi guys

Im trying to use an API running in AWS API Gateway.
This API is over https and i am using the SSL/TLS config of Caché.

set httpRequest = ##class(%Net.HttpRequest).%New()
set httpRequest.Server = server
set httpRequest.Https=1
set httpRequest.SSLConfiguration = "SSLPadraoAdapcon"

do httpRequest.SetHeader("Content-Type","application/json")
do httpRequest.EntityBody.Write(json)
do httpRequest.Post("/dev/router")

But im getting this error:

Introduction

We are in the age of the multiplatform economy and APIs are the "glue" in this digital scenario. Since they are so important, they are seen by developers as a service or product to be consumed. Therefore, usage experience is a crucial factor for its success.

While reviewing our documentation for our ^pButtons (in IRIS renamed as ^SystemPerformance) performance monitoring utility, a customer told me: "I understand all of this, but I wish it could be simpler… easier to define profiles, manage them etc.".

After this session I thought it would be a nice exercise to try and provide some easier human interface for this.

The first step in this was to wrap a class-based API to the existing pButtons routine.

I was also able to add some more "features" like showing what profiles are currently running, their time remaining to run, previously running processes and more.

The next step was to add on top of this API, a REST API class.

With this artifact (a pButtons REST API) in hand, one can go ahead and build a modern UI on top of that.

For example -

I already talked about GraphQL and the ways of using it in this article. Now I am going to tell you about the tasks I was facing and the results that I managed to achieve in the process of implementing GraphQL for InterSystems platforms.

What this article is about

  • Generation of an AST for a GraphQL request and its validation
  • Generation of documentation
  • Generation of a response in the JSON format

In this 3-part series of articles, is shown how you can use IAM to simply add security, according to OAuth 2.0 standards, to a previously unauthenticated service deployed in IRIS.

In the first part, was provided some OAuth 2.0 background together with some IRIS and IAM initial definitions and configurations in order to facilitate the understanding of the whole process of securing your services.

Good morning -

I am attempting to pass some HL7 content (say, a complete ADT message) from one server to another via REST/JSON - for reasons.

I can get the data across but when I try to create an EnsLib.HL7.Message object from the message in the JSON body, I end up with just the start of an HL7 msg in the resulting object. Looks like: MSH|^~\&

The start of the code accepting the data looks like this:

Four Database APIs

A concurrent session in IRIS:
SQL, Objects, REST, and GraphQL

Kazimir Malevich, "Athletes" (1932)

"But of course you don't understand! How can a person who has always traveled in a horse-drawn carriage understand the feelings and impressions of the express traveler or the pilot in the air?"

Kazimir Malevich (1916)

Introduction

We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills?

There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:

I am trying to connect the external application. Authenticating via Two SSL,

I have the Client Cert, Private key and the Root Certificate

The connection is successful from local (both via terminal and as well via Postman)

But when trying from IRIS application by configuring the certificates in the SSL configuration, i am not able to successfully verify the SSl connections

When test from the ssl configuration with the endpoint and port its gives the error Error #988: SSL connection failed. SSL/TLS error in SSL_read(), SSL_ERROR_SYSCALL: I/O error (54)

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports. We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down. We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page. I am new to Cache so any help would be greatly appreciated.

I am trying to return a stream soap response using web services I can call my web service supply it with a xml string which works fine . I then work on that XML and try to return a Stream but all works in the production when my service receives the stream after I get the error as if its trying to copy stream to a variable and I am confused as to where that operation happens.

Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?

InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.

In this article, we would use InterSystems API Management to Load Balance an API.

In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.

There are many different reasons why we might want to do that, such as:

  • Load balancing to spread the workload across servers
  • Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
  • Canary deployment: we might publish the new version only on one server and move 1% of clients there
  • High availability configuration
  • etc.

ObjectScript Kernel Logo
Jupyter Notebook is an interactive environment consisting of cells that allow executing code in a great number of different markup and programming languages.

To do this Jupyter has to connect to an appropriate kernel. There was no ObjectScript Kernel, that is why I decided to create one.

You can try it out here.

Here's a sneak peek of the results:
