Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

Hello everyone!
Sorry for the vague title! But I wonder what would be the best way to easily import a large XML-file into a production, modifying it by deleting elements and nodes depending on what values are in those nodes/elements and later creating whole new XML-file from that?

I have gone through this: Using Caché XML Tools | Caché & Ensemble 2018.1.4 – 2018.1.8 (intersystems.com)

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

I want to call the REST endpoint and return the list of objects. I`ve created the method but it displays an error:

<METHOD DOES NOT EXIST>GetAllPersons+10^Lab3.RestClient.1 *Count,%ZEN.proxyObject

I need to create a simple REST application.
I`ve created an app:


Also here is a dispatcher class:

I am attempting to setup my first OAuth2 client, as we are adventuring into the realm of making FHIR API calls to our EMR from HealthShare Health Connect.

I have gone through and set up the Issuer Endpoint, and Client Configuration but now I want to test it and verify that the setup is correct. When I setup the Client Configuration, it would not allow me to use Discovery as it was saying I needed a "Client secret" but was not given one. So I set it up manually, thinking I hit all the information correctly.

Anybody know if there is a ObjectScript kernel for Jupyter? Would be kinda interesting to testing scripts, etc. And since we kinda have the language runtime in the VSCode ObjectScript extension I wonder if that could be utilized fora jupyter kernel?

I have a API that is returning on objext with four fields. Two are arrays that are empty. How can I define the message class property to ignore/handle "Messages" and "SharedRelations"?

I am creating a custom message class. How do I define @name and #text fields?

this? Property name As %String (%JSONFIELDNAME = "@name");

Hello!
I am trying access each "name" tag in the xml-file down below and want to display them through the trace in the production:

<?xml version="1.0"?>
<staff>
<doc type="consultant">
<name first="David" last="Marston">Mr. Marston</name>
<name first="David" last="Bertoni">Mr. Bertoni</name>
<name first="Donald" last="Leslie">Mr. Leslie</name>
<name first="Emily" last="Farmer">Ms. Farmer</name>
</doc>

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device." Not so precise.
I failed to achieve my expected READ/WRITE as TCP would offer.

Based on the successful solution for my 2nd contribution to the Contest
I used an adapted version for this package. And have some findings I'd like to share.

Multiple communication steps over CPIPE may take time.
You won't recognize it on a fast machine. But a slower box with
Windows + Docker Desktop + your browser (and more) is neither
"Speedy Gonzales" nor a "Road Runner". 🙂

A tool (^GLOBUFF utility) is available to check the database cache usage for each global variable.

You can run the utility directly or programmatically in the %SYS namespace.

Here's how to run the utility directly:

I wanted to provide a heads up of an improvement in how we generate and call method code in IRIS 2023.1.

A class in IRIS is composed of two main runtime components:
