#InterSystems IRIS

What is the point of having a dedicated registry if it does not work properly most of the time?

By default, all files created inside a container are stored on a writable container layer. This means that:

• The data doesn't persist when that container no longer exists, and it can be difficult to get the data out of the container if another process needs it.
• A container's writable layer is tightly coupled to the host machine where the container is running. You can't easily move the data somewhere else.

Hi.

I would like to exchange data with external system every one minute or even more frequent. So I need to trigger production process/operation every minute. How can I do it?

George James Software is excited to announce that a new version of Deltanji source control is now available.

hi,

I am trying to connect to an external MySQL database from IRIS 2023.1 platform. Does anyone know the right adapter to use? Where do you set up the DSN name?

Thank you in advance.

Hi all

I'm having trouble defining the mapping needed to take the very large base64 string in OBX:5.5, and map it to an XML virtual document property that supports Stream.GlobalCharacter. I know from within the DTL you have to use custom code to manage the segment due to its size.

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up.

But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.

Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:

1. Start jobs.
2. Wait for all jobs to report success using $System.Event.WaitMsg().
3. Send Commit or Rollback using the $System.Event.Signal().

Continuing with the series of articles on voice file management, we are going to see how we can convert text into audio and receive the file with the chosen voice.
We will also explore how a service from OpenAI can help us analyze a text and determine the mood expressed in it.
Let's analyze how you can create your own voice file and how it can “read” your feelings.

I want to create a folder directory through code, but I don't know how to write it

I'm receiving a JSON payload via a REST API, I'd like to %JSONImport this stream into a class which extends %JSON.Adaptor. The problem is that the JSON is an array whose elements have no key (as you can see in the example JSON below). Right now I'm having to do some manipulations to convert the stream into a dynamic object and do a %Set which inserts a made up key "record" so "thingone" and "thingtwo" have an associated key that I can use when referencing "thingone" and "thingtwo"...such as record.GetAt(1).thingone

As noted in the previous article Native API has some limits.
So I did some research on a more Terminal-like interface that
provides me with access like a console or the IRIS terminal
to allow my $QUERY over a global and other nice commands
that are not supported/mapped in NativeAPI for ObjectScript.

The basic tools are well-prepared and available.

When using VS Code to develop with Object Script, the Server Credentials prompt for connecting to the IRIS instance is happy accept a blank for UnknownUser. See screen shot:
