#InterSystems IRIS

The most recent release of Serenji features our innovative gj::locate technology. It was a standalone tool we originally created for a Developer Community contest earlier this year, but we've incorporated it into our debugger after some great feedback from developers. 

It works by navigating you directly to the source of your server-side errors in just a couple of clicks - enabling you to quickly fix errors without the need to count tedious lines of code... and let's be real, who has got time for that when you're under pressure to fix this bug? 

It's simple and straightforward to use:

1. Click on the gj::locate panel in the status bar

2. Enter the ObjectScript error message or line reference from a class/.mac routine..

3. gj::locate then does the work for you by taking you straight to the corresponding line in your source code.

Easy peasy... and with time to spare to make yourself a coffee before your deadline! 

The video below shows it in action - let us know if you've already given it a go. Or, if you're interested in trying it out we offer a free 30 day trial license, just drop me a message through the Developer Community or email us at info@georgejames.com.

I have a requirement which comes down to evaluating two fields, if they are both empty then provide a default value.

If one is empty but the other has a value, then set the empty one to the field with a value.

The screenshots are not the actual fields, I was just using the dtl and fields to prove out the solution.

When I saved and compiled in the Management Portal I got an error, but it still compiled.

Hey Community,

Get ready for the next French Stream on InterSystems Technologies!

The new monthly event hosted by @Guillaume Rongier for French-speaking developers familiar with InterSystems technologies will be live stream October 7th at 12:00 Paris time. You will discover all the news and tips related to our solutions!

On the Agenda:

Hi developers, 

Serenji 3.2.0, the latest version from George James Software, was released last week and our current users have been enjoying trying out the new features (which you can find more about here). 

If you're thinking about trying Serenji for the first time, we've made it easier to get set up by adding a walkthrough on the VS Code Welcome page. It takes you through: 

• Setting up the server components.
• Selecting a server namespace.
• Saving and extending your workspace.
• Requesting a debug license (don't forget we offer a free 30 day trial!) 

We've also added prompts and guidance throughout VS Code to open and add Serenji folders to your workspace and when going to run and debug code. 

This is just one of the ways we've enhanced the Serenji debugger to make straightforward and easy to use - so all you need to do is focus on your code.

Hi Team,

I want to consume(call) third-party API by passing JSON as a request from Iris.

I'm trying to install IRIS 2021.1 in the Ubuntu 18.04 but all the time I got the message below:

Hello,

We upgrade from CACHE 2016 to IRIS 2021 and when we try to start a production gives the error behind.

I think the error could be that the Ens.Director is deprecated on IRIS 2021, is this possible?

When overwriting the Read method (that has a %CacheString return type) on a new class that inherits %Stream.FileCharacter class, returns an error about incorrect return type, must be Binary, even if it matched the real signature.

Looking at the compile global information we can see:

^oddCOM("%Stream.FileBinary","m","Read",42)="%Library.Binary"

After further investigation we realise that there is a generator method looking at the OdbcType class definition.

Setting LONGVARCHAR results in:

^oddCOM("User.CStream","m","Read",42)="%Library.String"

i noticed -by reading .INT files of one class- that some of embedded sql select statements code blocks translates into code that uses lock command.

even if i use %nolock in the select, still cursors and arrow referencing notations "->" have the same results.

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?

Since I saw many posts on Developer Community related to Python, and the very good articles and application written by @Eduard Lebedyuk I was wondering: "As a Object Script developer, why would I want to use an other language in Object Script?

Over the past year or so, my team (Application Services at InterSystems - tasked with building and maintaining many of our internal applications, and providing tools and best practices for other departmental applications) has embarked on a journey toward building Angular/REST-based user interfaces to existing applications originally built using CSP and/or Zen. This has presented an interesting challenge that may be familiar to many of you - building out new REST APIs to existing data models and business logic.

Hello everyone. I am hoping someone here can help me get my local instance running. I have set up these local instances in the past (pre IRIS) and never had much trouble, but I have spent so much time the last couple days trying to work through this problem and am out of ideas.
