Hi Developers!

We are going to establish a series of InterSystems IRIS Online Programming contests this year.

In March we started with ObjectScript CLI and here is the schedule of topics for the next few months:

• April - InterSystems IRIS with REST API
• May - InterSystems IRIS Native API application: use Python, JS, .NET, Java native APIs in your application to use IRIS
• June-July - InterSystems IRIS AI/ML solutions. IntegratedML as a bonus
• August - InterSystems IRIS for Health FHIR application
• September - InterSystems IRIS Full-stack application: IRIS as a server and UI on any framework and any form: and web, desktop, mobile UI
• October - Interoperability solutions for InterSystems IRIS and InterSystems IRIS for Health
• November - Analytics Solution using InterSystems IRIS
• December - Multi-model solution using InterSystems IRIS

All applications should be runnable with InterSystems IRIS in a docker container.

Hi

Sometimes I search mesage with inappropriate sql, It caused query hanged long time. 

So  Is it have way to find these hanged query and kill it?

Tks.

Every time I click Save on  System > Configuration > Memory and Startup page, I get "ERROR #5005: Cannot open file '/var/cache/cache.cpf_XXX' " error message, where XXX is a random number. This problem appeared some time ago without any clear reason. All file access right are seems OK.

Any ideas?

Hi,

Would appreciate some guidance on this. I am creating a transform to replace values using a functionset. But for some reason the values arent getting replaced. What I want to do is to replace if the observation value [For Eg: if Migraine should replace with M1]

<assign value='##class(ClassName.FunctionSet).illnessConv(source.{OBX():ObservationValue})' property='target.{OBX():ObservationValue}' action='set' />

My function set class is as below:

ClassMethod illnesConv(observationValue As %String) As %String [ Final ]
{
set ret = ""
set ^TEST("observation") = observationValue
if observationValue =

I am using studio 2015 version which does not have dynamic objects and I need to read xml and convert that to a json I have managed to come close to json string but with little difficulties .I need to be able to identify the root element and specify where to put braces between objects  anyone  with any idea is welcome he is my code so far

ClassMethod WriteNodes(myfile As %String = "C:\Testdata\data.xml")
{
  set status=##class(%XML.TextReader).ParseFile(myfile,.textreader)
  
    if $$$ISERR(status)
      {
	    do $System.Status.DisplayError(status) 
	    quit
	  }

I want to know how can I convert XML String intro a %SerialObject.

This is an example:

Purpose

Over the Easter Weekend I touched on some deep learning classifier for Covid-19 Lungs.  The demo result seems fine, seemingly matching some academic research publications around that time on this topic. But is it really "fine "? 

Recently I happened to listen to an online lunch webinar on "Explainability  in Machine Learning", and Don talked about this classification result at the end of his talk:

The above figure is also presented in this research paper: “Why Should I Trust You?” Explaining the Predictions of Any

Hello Community,

we need your help with Cache 2017.2 freezing on Linux machine.

Since we moved our primary production Cache from Windows to Linux in the begging of this year, we have experienced system freezing twice. Yesterday without any good reason Cache stopped to respond with the log shown below.

Questions:

• Any idea what could cause WRTDMN freezing?
• What actions it makes sense to take in order to have enough info when the system freezes next time.

Hi -- at a customer site we have 8 Access Gateways, with a couple of different load balancers that decide which projects go to which subset of AGs.

We're about to go live with a project that uses a subscription, and we have that subscription pointing to one of the AGs.  What if that AG goes down?  The project is dead until the AG is back up.  The subscription forces us to pick an AG that's registered in the Gateway Registry -- I don't see a way to get a cluster or load balancer address in there.

Has anyone found a way around this?

I'm wondering if anybody has done an implementation of the https://www.shibboleth.net/products/service-provider/ interface in Caché / IRIS to have a application running in Caché / IRIS be acception the shibboleth tokens and data as  usage credentials.

Does anyone use EnsLib.ITK.DTS.Framework.Operation.DTSTransferFile ? and how id you manage the transition to MESH?

I just noticed this PR from 2011

https://www.intersystems.com/news-events/news/news-item/itk-2-0-0-compliance-for-intersystems-ensemble-makes-it-easier-and-cheaper-for-nhs-trusts-to-exchange-information/

which led me to this class EnsLib.ITK.DTS.Framework.Operation.DTSTransferFile 

Given this was 2011, and DTS (now called MESH) is widely used by GP practices , I'm hoping someone in the community used this class?

If so - how did you manage the transition to MESH in Jan-2017?

FHIR Server and API Manager for MIT COVID-19 Challenge by Steven LeBlanc

This demo shows how InterSystems API Manager (IAM) can be used to view and test FHIR resources with InterSystems IRIS for Health. It comes pre-configured with a FHIR server, pre-populated with synthetic patient data. The new InterSystems API Manager (IAM) includes OpenAPI Swagger specs to quickly generate REST client code to work with many common FHIR resources.

This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

Hi community,

This article to give a description of my small library JSON Filter.

Why JSON Filter?

Search, sort data are common operations.

But … How to do this with JSON data?

You can use a %DocDB, It’s a good way for storing JSON and index the main properties.

However, JSON document is very flexible. It isn’t always possible (and not recommended) to index each properties to process the wished queries. A manual processing on a data subset is may be required.

In my opinion, this is not a funny part of the job. It’s a repetitive code with many loops etc...

JSON filter allows to process these

Hi Developers!

Excited to share with you that this week we reached 250 applications published on Open Exchange!

Thank you for sharing your open-source and commercial solutions running on InterSystems IRIS with InterSystems Developers Community and make your coding life more effective and happier!

Hi,

I am looking foi an API to retrieve one namespace´s default web application name. We have use some code to setup links to event log/mesage trace for monitoring emails. In perticular we did this with ensemble where the default csp webapplication name always is something like csp/<namespace/. Anyway when it comes to a healthshare installation the default path seems to be csp/healthshare/<namespace>.

To have an easy solution working for an ensemble and healthshare environment I rather like to use an API instead of evaluationg the kind of installation and then hardcoding the links to use.

I would like to chenge this cookie once user is logged into my system but I can't logout and

Is there a way to change to cookie or renew it?

During runtime I build an object which is essentially a wrapper over in-memory table:

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

I have complete control over object class, so if I need  to add something (or even change runtime internals), it's no problem.

Object may have different columns depending on runtime situation, but during one query execution the fields are
