Syndicate content 3 

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 agenda of topics for the next few months:

  • April - InterSystems IRIS with REST-API
  • May - InterSystems IRIS Full-stack application: IRIS as a server and UI on any framework and any form: and web, desktop, mobile UI.
  • June - InterSystems IRIS for Health FHIR application
  • July - InterSystems IRIS AI/ML solutions. IntegratedML as a bonus.

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

SQLBuilder is a flexible and powerful SQL query string builder for InterSystems IRIS,

With SQLBuilder you have nice and clean object oriented methods, instead of having to use concatenation and substituition to generate dynamic queries.

I am glad to say that VSCode-ObjectScript reached 4000 installs. Thanks to all of you who use it in their work.

VSCode-ObjectScript is an extension for VSCode which allows you to develop InterSystems based applications on ObjectScript using the modern code editor developed by Microsoft. Choice #1 editor amongst all developers worldwide by Stackoverflow survey 2019.

Some short notes about how to install and configure it you can find here.

If you need any help with a migration process of your development team to VSCode, please contact us by info@caretdev.com.

Hi-

I am trying to create a simple example of allowing binary (tiff) files to be selected and uploaded asynchronously to an IRIS for Health back-end.   I have managed to write the HTML and Javascript which works great with regular text / ascii files, but fails with binary files.

When I upload a binary file (tiff) image I get garbage like this on the database server

Hello,

 

We have a Service which behaves differently even though two equal Soap UI XML requests are being sent, from different systems.

 

When it is being sent from the other system, our Service's log shows:


ERROR <Ens>ErrGeneral: invalid HTTP version'xmlns:ges="http://XXX.XXXXXXXXX/GestionPacientes">'  

 

When we send the same XML message from SoapUI, it is being processed by our system.

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 Everyone,

I've been working on deploying an IRIS for Health environment in EKS. There is a video session in the InterSystems learning portal about this feature but I have not succeeded in finding the proper documentation and resources to use this in my Kubernetes cluster.

Has this been deprecated/discontinued? Any idea where can I find the resources? Should I stick to StatefulSets instead of using the IrisCluster resource type provided by this operator?

Loading your IRIS Data to your Google Cloud Big Query Data Warehouse and keeping it current can be a hassle with bulky Commercial Third Party Off The Shelf ETL platforms, but made dead simple using the iris2bq utility.

Let's say IRIS is contributing to workload for a Hospital system, routing DICOM images, ingesting HL7 messages,  posting FHIR resources, or pushing CCDA's to next provider in a transition of care.  Natively, IRIS persists these objects in various stages of the pipeline via the nature of the business processes and anything you included along the way.  Lets send that up to Google Big Query to augment and compliment the rest of our Data Warehouse data and ETL (Extract Transform Load) or ELT (Extract Load Transform) to our hearts desire.

A reference architecture diagram may be worth a thousand words, but 3 bullet points may work out a little bit better:

  • It exports the data from IRIS into DataFrames
  • It saves them into GCS as .avro to keep the schema along the data: this will avoid to specify/create the BigQuery table schema beforehands.
  • It starts BigQuery jobs to import those .avro into the respective BigQuery tables you specify.

While I can query the HL7 message class EnsLib.HL7.Message (EnsLib_HL7.Message for SQL) to my heart's content in the SQL Shell or the Management Portal's SQL page, I can't seem to SELECT anything other than ID/%Id from an ADO/ODBC client. Properties such as TimeCreated, Name, MessageTypeCategory, etc. all seem to prevent the query from ever completing EXCEPT when I provide the ID as part of the WHERE criteria.

This works fine in the Management Portal and Shell:

InterSystems and Intel recently conducted a series of benchmarks combining InterSystems IRIS with 2nd Generation Intel® Xeon® Scalable Processors, also known as “Cascade Lake”, and Intel® Optane™ DC Persistent Memory (DCPMM). The goals of these benchmarks are to demonstrate the performance and scalability capabilities of InterSystems IRIS with Intel’s latest server technologies in various workload settings and server configurations. Along with various benchmark results, three different use-cases of Intel DCPMM with InterSystems IRIS are provided in this report.

Hi,

I created a BS with a SQL Inbound Adapter.

Query = "SELECT rowid, fname ,lname,datesent  
                   FROM labs
                   WHERE datesent IS NOT  NULL"

DeleteQuery = " update labs set datesent  =  Getdate() where rowid = ?"

KeyFieldName = "rowid"

i am getting the following errors.

"NOT assuming network disconnect error based on: Gateway failed: DropStatement."

"Skipping previously errored row '235'"

Hi,

I have a production with a BS calling a BP calling another BP and so on and finally a BO. All calls are made using SendRequestSync.

The initial request is passed by value. The response is passed by ref and I allocate memory for it in the BO, hoping that it will go back to the initial caller in the BS, but it does not.

It looks like the following:

Hello,

I've always worked with typical web applications (a bunch of code files that sit in a server that connects to an RDS). Now our team is responsible for different IRIS for Health environments. We are currently working to set up the local dev environment and this is the current scenario:

* IRIS for Health local development server is running in a container

* Developers are using VSCode with the objectScript plugin

* GitHub as a version control system for the code and configuration.

I'm always on the lookout for tools that make the development and testing of my interfaces more efficient. A couple of years ago I came across HL7 Spy, from Inner Harbour Software. It quickly became my go-to tool for running message comparison reports for interface engine migrations, message statistics gathering, and troubleshooting message receipt and delivery. It also offered enhanced functionality for things like fetching messages via sftp that other tools don't provide.

I've recently been working with HL7 Spy's author, Jon Reis, to enable support for fetching messages directly from the Ensemble message store. Its SQL Loader feature now has native Caché/IRIS support, and I've contributed a small server-side class to support the extraction of messages using it.

Hi Developers!

Another way to start using InterSystems ObjectScript Package Manager is to use prebuilt container images of InterSystems IRIS Community Edition and InterSystems IRIS for Health Community Edition.

We deploy this IRIS images on DockerHub and you can run it with the following command:

docker run --rm -p 52773:52773 --init --name my-iris -d intersystemsdc/iris-community:2019.4.0.383.0-zpm

Launch a terminal with:

docker exec -it my-iris iris session IRIS

And install zpm-module as:

USER>zpm 

zpm: USER>install objectscript-math

[objectscript-math] Reload START

[objectscript-math] Reload SUCCESS

[objectscript-math] Module object refreshed.

[objectscript-math] Validate START

[objectscript-math] Validate SUCCESS

[objectscript-math] Compile START

[objectscript-math] Compile SUCCESS

[objectscript-math] Activate START

[objectscript-math] Configure START

[objectscript-math] Configure SUCCESS

[objectscript-math] Activate SUCCESS

zpm: USER>

And use same commands for InterSystems IRIS for Health using the tag: intersystemsdc/irishealth-community:2019.4.0.383.0-zpm

The images are being published on IRIS Community Edition and IRIS Community Edition for Health repositories of Docker Hub.

We will update tags with every new release of IRIS and ZPM.

Happy coding!

I was searching for the most simple way to connect from visual studio code to my local instance via terminal without having to change any window.

I know this can also be achieved via telnet but seems a bit overhead if you're in your local machine.

For me the simplest sollution is to open a terminal window in VS Code, navigate to the /bin folder of your instance installation and run .\csession.exe INSTANCENAME

For simplicity you can just include your /bin folder in your path so you don't even need to navigate there

Hi,

I need to set the label of a custom setting in the portal instead of the name of the associated property, eg.:

Class SomeClass Extends (Ens.BusinessService, %ZEN.Portal.ContextSearch)

{

Property ABadPropertyNameToChange As %Boolean;

Parameter SETTINGS = "ABadPropertyNameToChange:CustomSettingsSection"
}

will result in this in the portal

-------------------------------
CustomSettingsSection

ABadPropertyNameToChange

[ ]
