#InterSystems IRIS

During some consulting activity, I found at the client's site CACHEAUDIT database of more than 100 GB size. The reason was simple: several processes produced a great amount of %System/%System/OSCommand audit records due to frequent external calls ($zf(-100,.)). As it is well-known, those events can be easily disabled systemwide, while this can be hardly considered secure enough. Reducing the number of days before audit cleanup from default 62 to some reasonable figure (e.g.

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.

We have multiple NTE segments in the ADT message.  I need to loop through all of the NTE segments looking for "NAVIRADTHPT" in the NTE-4 field.  I have yet to get this to work using the following code.  

HL7.(NTE:4()) Contains "<NAVIRADTHPT>"

Here's how the segments look.

NTE|1||This patient is currently being seen for radiation therapy.|AHRADTHPT||20210223093342
NTE|2||This patient is currently being seen for radiation therapy.|NAVIRADTHPT||20210223113634

I've also tried it this way with no luck.

HL7.(NTE():4) Contains "<NAVIRADTHPT>"

Any help would be greatly appreciated!

Can a license be reserved for a specific user or group of users? So if I have 20 available licenses, only allow other users to use 19 of them while keeping one open for this specific user?

Hi all

I've been looking into how to convert some images with IRIS and saw some recommendations on the forums around using image magick.

However I can't seem to get this working using ZF100 and on windows server and I'm wondering if I'm missing something really obvious as I've not used IRIS to call third party applications before.

If I run via a Windows CLI on the server, it works fine, e.g:

magick "D:\1221701739_20190716134351965_1_0.jpg" -resize 640x480 "D:\1221701739_20190716134351965_1_TEST.jpg

But I keep getting NOTOPEN when I attempt this in IRIS.

I want to operate on the class in enslib, but I don't have write permission. How can I modify the permission with code, or which table is given write permission

ERROR:#5388 - You do not have write permission on the database class ,so class lock cannot be obtained .

Hey everyone,

The InterSystems Grand Prix Contest is over. It was an incredible competition with a record number of participating apps and developers! 

Thank you all for participating! And now it's time to announce the winners! 

A storm of applause goes to these developers and their applications:

Hey Developers,

Enjoy watching this brief explanation of a new feature in IRIS RAD Studio – a new project by @José.Pereiraand @Henrique.GonçalvesDias:

⏯ Automated user management in IRIS RAD Studio

Transition and transfer from Caché to Iris databas. I have a question about import-export from Caché to Iris. Someone will tell you how to do this with a regular one, i.e. using standard procedures from Caché itself or Iris? I am asking in connection with the planned transition from Caché to the new IRIS DBMS.

Hey developers,

We want to hear from you! Give us your feedback on the InterSystems Grand Prix Contest! Please answer some questions to help us improve our contests.

👉🏼 Quick survey: InterSystems Grand Prix Contest Survey

Bulid REST API application built with ObjectScript in InterSystems IRIS. It also has OPEN API spec,  can be developed with Docker and VSCode, can be deployed as ZPM module. can be used as Overbooking System data REST api.

What's Hotel Overbooking Management System?

The overbooking management system combines the unique conditions of the hotel, such as room prices, order channels, customer needs (etc.).

I have a quick question regarding swizzled objects.

I have an original object, say Object a, I am working with.

I set a property a.something.somethingother.somethingelse.myNewProperty  to some value x.

Then at some point I am saving a and continuing to work with it.  I assume here by saving a, I saved myNewProperty as well. (as it should work)

At some point  I would like to make certain that I have correct value in my myNewProperty, so since I happen to know it's ID I 
open it directly:
Set ref=##class(somethingelse).%OpenId(Id)
but when I try to look at my ref.

I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 4:

1. All data are stored in Globals and Global names start with ^. Example of global: ^animal. Global can have multiples locations to the data ("sub data"). Example: ^animal(1).
2. ^%* globals are accessible from any system-wide (from any namespace).
3. Globals enables IRIS to support multimodel data (object, relational, document, multidimensional, etc).

@José Pereira and I created a good project, and we want to introduce a few words about this project to you.

What is IRIS RAD Studio?

IRIS RAD Studio is our idea of a low-code solution to show what's possible,  to make the developer's life easier. 

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.

Migration from Caché to IRIS can be quite a challenge if your code is grown over many years
and probably not so clean structured as you may like it. So you face the need to check your
migrated code against some reference data. A few samples might not be a problem,
but some hundred GB of data for testing might be.  

A possible step could be to have your fresh code in IRIS but leave your huge datastore on Caché and connect both environments over ECP.  I have created a demo project that gives you the opportunity to try this based on 2 Docker images with IRIS and with Caché connected over ECP.

Hey Developers,

This week is a voting week for the InterSystems Grand Prix Contest! So, it's time to give your vote to the best solutions built with InterSystems IRIS.

🔥 You decide: VOTING IS HERE 🔥

How to vote and what's new?

I can't find a case of spark or Kafka connecting to InterSystems Iris on the Internet. Are there any related resources  can share?

Hi Developers!

Thank you for using ZPM Package Manager and contributing more and more useful packages to the public registry!

But as you already aware ZPM packages are always deployed with source code.

Do you think we need to add the option to deploy without source code - e.g. if you want to deploy a commercial package?

Will you develop commercial modules if there will be an option and deploy it with ZPM?

How do you deploy commercial applications today?

Hi all,

I'm trying to access via JDBC my community installation but the connection is always rejected. The same code (python code) using the stand-alone version of Intersystems IRIS works fine.

Is the community edition limited in this case? I can't see it in the official documentation: https://irisdocs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Pag…

Organizations around the world lose an estimated five percent of their annual revenues to fraud, according to a survey of Certified Fraud Examiners (CFEs) who investigated cases between January 2010 and December 2011. Applied to the estimated 2011 Gross World Product, this figure translates to a potential total fraud loss of more than $3.5 trillion (source: https://www.acfe.com/press-release.aspx?id=4294973129).

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!

I finished my participation in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during this the training final day. Tips presented in the day 5:

1. %SYSTEM package has general utiliy classes. Use $system.class.Help() to list the utilities. The main %SYSTEM classes are Encryption (industry encryption methods), OBJ to manage classes and objects, Security for security methods and SQL to use SQL language.
