ZPMshow, a helper for tired fingers

The offer of ZPM is growing daily and the short names and
acronyms of the offer are sometimes hard to understand and
also hard to type with my lazy fingers.

So I decided to have

  • a listing with the descriptions from the repository,
  • split in short junks to avoid backscroll,
  • controlled forward / backward scrolling,
  • the option to select my packages by number,
  • to install or uninstall with limited typing.

It runs with do ^zpmshow

Hi Developers!

This post describes how you could publish your InterSystems application on Open Exchange.

What is the InterSystems application?

It could be anything, which is built with InterSystems data platforms or to help work with InterSystems data platforms: InterSystems IRIS, InterSystems IRIS for Health, InterSystems HealthShare, InterSystems Ensemble and InterSystems Caché. This could be tools, frameworks, adapters, examples and business solutions.

Why publish on Open Exchange?

InterSystems Open Exchange is an "App Central" for the solutions in InterSystems. It's the first place where the developer goes to look for tools, frameworks, and examples on InterSystems IRIS. And Open Exchange brings the added traffic to your solution which could be converted into leads.

We are having a set of business development tools for published Open Exchange applications. This definitely makes your InterSystems application more noticed.

Submitting an application

Suppose you have a library with open source published on Github which you want to publish on Open Exchange. For the purpose of a demo, I'll fork this remarkable project of @Peter Steiwer ObjectScript-Math which I forked and renamed to object script-super-math.

Is there a way to lock at the record level? I know that you can lock at the table level:

&sql(UNLOCK mytest IN EXCLUSIVE MODE)

but am unable to find a way to lock just at the record/row level.

Would this also affect a SELECT statement done on the record?

Version history for the production class

Last week I was onsite with a new customer of ours, implementing Deltanji to give them control of their development and deployment cycle. One particularly satisfying part of the visit was seeing their pleasure at how their production class now records its changes over time, allowing them to quickly diff the versions and see what configuration items have been added or what settings altered. ​

Atelier and overriding

I'm used to using Class/Refactor/Override in Studio to override methods, properties, xData blocks, etc regularly.

I can't see how to replicate that in Atelier at the m moment. Is this possible ?

This week I was able to demo a proof of concept for our FMS interface on traffic cop architecture to my team. We are working on modernizing an Interoperability production running on mirrored Health Connect instances. We deploy IRIS workloads on Red Hat OpenShift Container Platform using InterSystems Kubernetes Operator (IKO). We can define any number of replicas for the compute stateful set where each compute pod runs our Interoperability production. We introduced Horizontal Pod Autoscaler (HPA) to scale up the number of compute pods based on memory or CPU utilization.

Hi Community,

We are glad to invite you to the upcoming Interoperability Contest Kick-off Webinar: Building Sustainable Solutions! The topic of this webinar is dedicated to the Interoperability programming contest.

In this webinar, we'll show you some of the general principles and problems of solving sustainability challenges, as well as some great ideas that came up in hackathons for inspiration and do's and don'ts.

Also, we’ll discuss and answer the questions on how to build interoperability solutions using InterSystems IRIS and IRIS for Health.

Date & Time: Monday, August 29 – 09:00 AM EDT

Speakers:
🗣 Tomas Studenik, CEO of Insane Business Ideas and co-founder of Caelestinus
🗣 @Dean Andrews, Head of Developer Relations
🗣 @Evgeny Shvarov, InterSystems Developer Ecosystem Manager

Exam-taking

What are the differences among HealthShare Health Connect HL7 Interface Specialist, InterSystems IRIS Core Solutions Developer Specialist and HealthShare Unified Care Record Technical Specialist these 3 certifications? And what are the prerequizites for these 3 exams?

Hi,

I've setup an operation that pulls text from an MDM message and uses it to generate a csv file. I'm having issues as our vendor is sending the file with a carriage return (as shown below) to signify the next line but Healthshare is recognising this as a new segment which causes an error.

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?

I've recently encountered a HS Caché that won't start informing that Collation 30 is not available, but I have not found an easy way of knowing what collation is 30.

I've found that the following command returns the ones from the current locale, but not from all locales:

Set Rset = ##class(%ResultSet).%New("%Library.Collate:CollationList")

d Rset.Execute()

While (Rset.Next()) {zw Rset.Number_": "_Rset.Name}

Thank you

Hi, Community!

And so I continue with publishing of the tasks for the Final round of InterSystems Contest on InterSystems Caché and DeepSee as a part of IT Planet Student Championship in Sochi. This year we had about 2 000 participants in InterSystems Contest.

One of the tasks for the finals was to crack the black box and another to output 9876543210!

Here's the next task: gravity!

Hi,

I've built a custom HL7 searchtable, but wish to remove some of the items.

I've removed the items I no longer wish to index recompiled the custom searchtable, however the previous searchtable values are available when searching messages in the namespace.

Do I need to rebuild the index for this searchtable to purge searching the old values?

I have stop and started the production.

Regards

Stuart

How do I write DDL script for collection properties?

For example I want to create the following class:

Class SQLUser.Person {

Property Name As %String;

Property FavoriteColors As list Of %String;

}

My DDL script looks like this:

CREATE TABLE Person (Name varchar(50), FavoriteColors ???)

What I find really useful about IRIS when teaching my subject of Postrelational databases is the fact that it is a multi model database. Which means that I can actually go into architecture and structure and all that only once but then show the usage of different models (like object, document, hierarchy) using the same language and approach. And it is not a huge leap to go from an object oriented programming language (like C#, Java etc) to an object oriented database.

However, along with advantages (which are many) come some drawbacks when we switch from object oriented model to relational. When I say that you can get access to the same data using different models I need to also explain how it is possible to work with lists and arrays from object model in relational table. With arrays it is very simple - by default they are represented as separate tables and that's the end of it. With lists - it's harder because by default it's a string. But one still wants to do something about it without damaging the structure and making this list unreadable in the object model.

So in this article I will showcase a couple of predicates and a function that are useful when working with lists, and not just as fields.

Hello everyone,

I talked to a colleague and he said that at the other company he worked, they converted a routine into a line and used that in the terminal like a command. So, I want to know if we have this function native in Intersystems products, or maybe was a program they created, my colleague doesn't remember and this would be useful for me now.

Edit:

Example of function:

Hi team,

I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?
