Remote proxy objects via dynamic dispatch

This article created as side effect of preparations to the longer set of articles about simple, but still handy MapReduce implementation in Caché. I was looking for relatively easy way to pass arguments to (potentially) multiple targets via remote calling facilities. And after several attempts I have realized that we do have very powerful mechanism in the Caché ObjectScript which might be of particular help here – dynamic dispatch for methods and properties.

Interview Questions

There is documentation. A recruitment consultant wants to quickly challenge candidates with some relevant technical questions to a role.

Can they automate making a list of questions and answers from the available documentation?

Interview Answers and Learning

One of the most effective ways to cement new facts into accessible long term memory is with phased recall.

Replacing ZEN - Index to articles

Hi All
This is the index to a series of articles I hope to create over the coming months.

ZEN and ZEN Mojo are no longer being actively developed by Intesystems - this is a great shame as it is a fine product that works so well for business applications.
However ZEN is a 15 year old product and I need a path forward to replace the ZEN UI with a supported development framework.

This article is an index of the other articles I have, or plan to write. - the articles will be subject to change as I develop my thoughts and climb the learning curve.

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.

InterSystems Supported Platforms Update Feb-2023

InterSystems Supported Platforms Update Feb-2023

Welcome to the very first Supported Platforms Update! We often get questions about recent and upcoming changes to the list of platforms and frameworks that are supported by the InterSystems IRIS data platform. This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tricky business and this shouldn’t be considered a committed roadmap.

We’re planning to publish this kind of update approximately every 3 months and then re-evaluate in a year. If you find this update useful, let us know! We’d also appreciate suggestions for how to make it better.

With that said, on to the update…

Same old terminal but in web

We have Webterminal around for quite a while, but it was limited, not all features worked there. There was no shell support or the latest feature as embedded Python support. There are some issues with tools that require programmer mode. Basic Authorization, not as handy as simple login page, where you could have options to add own login page, in case if you would wish to change the way how to login to the application, such as using SSO.

With the original iris terminal, wrapped into a web form, using most used in the web world xterm.js, used in tools like VSCode as well, with some magic from Python, which helped with interprocess tty. We can get the the terminal in the web, in the full capacity.

VSCode: Formatter not found

Hi,

I am using VSCode together with IRIS 2021.1.
When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.

ID vs %ID in tables

What is the difference between %ID and ID in a database table? Both seem to reference the same column labelled ID.

For context, I am trying to create a viewer class for an existing persistent class.

Let us call the persistent class A, with SqlTableName = OldA.

The viewer class will be B with SqlTableName = A and ViewQuery = {select %ID, <other fields> from <some other class with the same fields as A>}

I am writing a static SOAP response to simply test connectivity. The end users is getting an error "Message: The processing instruction target matching [xX][mM][lL] is not allowed.", which I believe is related to white space. if I observe the response, it looks like there are two blank lines between the header and the body, which I'm guessing is the white space problem. But I can't seem to get rid of it.

Any ideas?

Most transactional applications have a 70:30 RW profile. However, some special cases have extremely high write IO profiles.

I ran storage IO tests in the ap-southeast-2 (Sydney) AWS region to simulate IRIS database IO patterns and throughput similar to a very high write rate application.

The test aimed to determine whether the EC2 instance types and EBS volume types available in the AWS Australian regions will support the high IO rates and throughput required.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD
  • Why containers?
  • Containers infrastructure
  • CD using containers
  • CD using ICM

In this article, we'll build Continuous Delivery with InterSystems Cloud Manager. ICM is a cloud provisioning and deployment solution for applications based on InterSystems IRIS. It allows you to define the desired deployment configuration and ICM would provision it automatically. For more information take a look at First Look: ICM.

Level up your XDATA

XDATA is used for a whole host of ISC libraries to store things like Zen pages, BPL logic and DTL transformations.

XDATA is the equivalent of XML config files of the JAVA world and JSON config files of the JavaScript / NPM world.

Whilst Atelier looks to shift source code to the disk, XDATA will remain a key component to source control our projects config / meta data.

HealthShare HealthConnect and Information Exchange version 15.03 support import transformations from C-CDA 2.1 to SDA. You can find these transforms in your installation's csp/xslt/SDA3 directory. For general information about import transforms, see "CDA Documents and XSL Transforms in HealthShare" in Overview of Health Connect.

Among the enhancements to import functionality added in connection with C-CDA 2.1 support is the ability to preprocess your C-CDA input files prior to the transformation done for import.
