Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

We have a service where 3 groups, each with multiple users, potentially have access to make changes to the live service. With the best will in the world, each group doesn't always tell every other group about changes made.

Hi noble devs!

Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:

{ name: "John", 

surname: "Doe"}

will have issues while saving the dynamic object to a class Sample.Person with:

Class Sample.Person Extends (%Persistent, %JSON.Adaptor)

{

Property Name: %Sting;
Property Surname: %String;
}

As soon as the case is not the same... 

Is there any setting to fix

Thank you community for translating an earlier article into Portuguese.
Am returning the favor with a new release of Pattern Match Workbench demo app.

Added support for Portuguese.

The labels, buttons, feedback messages and help-text for user interface are updated.

Pattern Descriptions can be requested for the new language.

The single AI Model for transforming user prompt into Pattern match code was fully retrained.

Values to Pattern Code Model also retrained

The separate AI model for generating Pattern match code from a sample list of values has been retrained.

Can someone point me to learning resources / documentation for Intersystems Terminal? I have scoured YouTube, Intersystems documentation, and the internet. Many of the Object Script commands I found don't work (and that are listed here) do not work in the version of terminal that I have:

https://docs.intersystems.com/ens201817/csp/docbook/DocBook.UI.Page.cls…

So far, I have only found 1 YouTube video that presented commands that 'actually' work my Cache terminal install:

https://www.youtube.com/watch?v=F3lw-2kGY6U&list=PLp4xNHWZ7IQmiSsryS0T3…

I was wondering what best practice was for using macros in Embedded Python, i.e. iris.execute('$$$MACRO()') or something else. Does anyone have insight into this?

Hello Community,

When handling a %CSP.REST API response for a custom endpoint, how can I capture or access the response content before it is written to the output buffer and sent through the Web Gateway to the UI?

In manually created REST services (for example, with a route like:<Route Url="/test" Method="POST" Call="User.Sample:Test" Cors="true"/> ),
the response is typically written from within any class method in the execution flow.

Is there a way to intercept or log the response content before it is sent to the client?

Thanks!

I'm running the image "containers.intersystems.com/intersystems/irishealth-community:2025.1" as a container on my local Docker desktop.

Now I want to set up an ODBC SQL connection, but I don't know how to do it.

I have tried various ways without success. Like building my own image (see "Dockerfile" description below).

I have also added ODBCINI variable in my docker-compse (see "Docker-compose.yml" description below).

Anyone done this before?

I'd really appreciate some help.

Thanks.

I have notified that on several servers the IRISTEMP database is reported as only a few GB in size while on the disk where it's located, the IRIS.DAT file is much bigger (eg: 3GB reported in Portal (including free space) while file on the disk file is 121GB). The last modification date of IRIS.DAT is recent so I'm not looking into a location no more in use.

Is there an explanation for that difference in size ? 

I know temporary databases are special in a way they are not always stored on the disk, here is what InterSystems says about it :

Changes to temporary globals are not written to disk.

Maybe this is well known but wanted to help share.

Consider that you have the following persistent class defintions

Class Sample.Invoice Extends (%Persistent, %Populate)
{
Parameter DSTIME = "AUTO";
Property InvoiceNumber As %Integer(MINVAL = 100000) [ Required ];

Index InvoiceNumber On InvoiceNumber;
Property Provider As Sample.

Hi Community,

⏯ HealthShare Health Connect Mirroring Simplified @ Global Summit 2024

I'm trying to open a TCP connection to a remote system. The Caché command I'm using to open the connection is OPEN "|TCP|"_PORT:(IP::"PSE"):10 where PORT is a port number in the range 40000 to 40100 and IP is a standard IPv4 addess like 10.200.100.50 the connection appears to open because $TEST becomes 1. I'm then writing to the open port with USE "|TCP|"_PORT:(::"S") WRITE "some text",*-3 It's a windows system

w $zv Cache for Windows (x86-64) 2017.2.2 (Build 865) Mon Jun 25 2018 10:45:31 EDT I'm under the impression that the O/S handles the I/O for TCP connections.

I'm confused about the differences between a namespace and a database.

I understand that a database is a single IRIS.DATA file in a directory in the os hosting IRIS.

What is the difference between a namespace and a database?

Can I write data into a database without specifying a namespace?
If so how do I write to a particlar DB in objectscript?

Does a database have to be in a namespace?
Can a database be in more than one namespace?

Can a namespace have only one 'routine' database and only one 'data' database?

I have a database that is 2TB in size (from a LIVE system).

I would like to defragment it but I have some questions. I took a look at official documentation but it does not help.

• Is is possible to get a measurement about how much database is fragmented ? (eg: a percentage). Most operating systems are able to give a an indication about how much a filesystem is fragmented before any operation.
• The database is on a LIVE server, the IRIS service is restarted every night (around 1AM). Because of that I can't run defragment continuously. I don't think it will be able to complete under 24 hours.

Hi Community,

While writing an article yesterday, I realized I was so busy with people who came to the Developer Community table at the Tech Exchange that I forgot to take photos for you. Luckily, I realized the error of my ways and corrected my behavior accordingly 😉

So, let's look at what happened on Tuesday at the InterSystems Ready 2025! It began with a speech of Scott Gnau about the approach and architecture of InterSystems Data Platform and how it is different from all other DBMSs:

Is there a link we can use to invite other devs to ( so we can get credit for brining them in?)

Hi Guys,

I'm trying to use %Net.WebSocket.Client to collect data from a sever,

and part of that I needed to implement Two classes (SX3.Production.HTTP.AdvCredenials  & SX3.Production.HTTP.AdvListener) as below for the purpose of Credentials & EventListener properties,   

Class SX3.Production.HTTP.AdvCredenials Extends %Net.WebSocket.ICredentials
{

Method GetPassword() As %String
{
q ""
}

Method GetUsername() As %String
{
q ""
}

Method GetSSLConfiguration() As %String
{
q "MySSL"
}

}

Class SX3.Production.HTTP.AdvListener Extends %Net.WebSocket.IEventListener
{

Method OnMessage(pContent As %Stream.

I am attempting to follow the tutorial at Publishing Web Services Using Caché | Caché Web Services QuickStart Tutorial | Caché & Ensemble 2018.1.4 – 2018.1.11 to build a toy SOAP web-service using Cache but am running into what I suspect are permissions issues, or perhaps setting up the "plumbing" to get an incoming request to call the web-service methods.

My HL7 message got "AR" (rejected ack code) and went to the suspended queue.  I re-submitted it (without editing it) but forgot to write down the details before doing so.  It got "AA" and everything works fine from there.

Now (the next day) I want to check with the downstream system why they returned "AR" initially.  Is there a way to search for the original message the got an "AR", along with any returned error message please?

Hi all,

We're developing a medical appointment app that connects doctors' schedules to an appointment provider.

The provider is returning us the appointment in the following format:

Thu Jul 03 08:20:00 CEST 2025

It means, 03 july 2025 at 08:20:00 Central European Summer Time (UTC+2)

But we need the following format:

2025-07-03 08:20:00+02:00

Is there any option to convert zone time code (CEST) to a UTC+x ?

How to convert zone time code (CEST, CET, ET, EDT, etc..) in its zone time in UTC (UTC+2, UTC+1, UTC-5, etc..) ?

Best regards
