I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.

My first question is whether this is actually necessary?

Intersystems provides External language server connections for various languages which,
from a development perspective, is great as I can keep my application code separate but still interact with the IRIS kernel.

It becomes more complex though if you are using Interoperability etc where you might end up with some code in IRIS and some code in another language.

What would be great is having an IRIS to IRIS language server where the application code and stay IRIS based but separate from the database?

I hit halt in Iris lite terminal within VS Code and was exited out to PS prompt. I was just curious what the best way / recommended way to get back into an InterSystems lite terminal would be? Perhaps it is just to start a new InterSystems lite terminal from a the options listed previously in this post https://community.intersystems.com/post/how-run-objectscript-commands-vs.... I was just curious if there was a way to kick it off again from the PS prompt?

Hey Community,

It's time for the new batch of #KeyQuestions from the previous month.

Here are the Key Questions of October chosen by InterSystems Experts within all Communities:

Hi everyone,
I am new to "git-source-control", what i am doing so far will explain you in few steps.
1. installed git-source-control into a namsapace TEST using ZPM "install git-source-control"
2. configure the git settings and created a new mapping for as such

Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.

Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.

Thank you to everyone who joined our Spooky Stories Contest 👻 on Global Masters and shared your eerie tales with us! We loved diving into your mysterious, thrilling, and downright spooky stories. It was tough to pick just one winner, but we finally have a standout story to celebrate.

And the winners are...

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.

An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.

Has anyone successfully tested the new THROUGH command in IRIS 2024.2 with a FOREIGN SERVER?https://docs.intersystems.com/iris20242/csp/docbook/Doc.View.cls?KEY=RSQ...

I have connected from a Docker instance to a VM. I was able to successfully set up the JDBC connection through the UI.

Does anyone know any InterSystems partners in Canada? A colleague with experience in IRIS asked me about this.

Hello Community,

I have a stream property which uses %Stream.GlobalCharacter and I set some dummy texts like "a1a2a3a4a5a6a7...."(more than 1024 characters) in to that stream and the stream values are not compressed. However, The streams are compressed If I use the Lorem ipsum is a dummy or placeholder text or other text "This is part four of a long memo." which length is greater than 1024

There are a select few in the group that have been using Github as a Local Client push to a Repository setup in GitHub. Questions were brought up today about the security, and possible issues when it comes to data being pushed in this method.

Looking over code we have noticed that there is Histogram data within some of the class files that could be considered a security issue. Does anyone else have concerns with the Histogram data being within the class files pushed up to github?

I've enabled the CallIn service (unauthenticated), but I'm still getting 'ImportError: IrisStart failed: IRIS_ACCESSDENIED (-15)'

Any clues?

Summary: if you concatenate filenames into /STDOUT and /STDERR in a $zf(-100) call, quote them.

I hit an <ILLEGAL VALUE> error from the following that initially stumped me. This was part of a unit test that worked perfectly fine on Windows, but when CI ran on Docker it failed:
