Hi everyone,

I'm working with JavaScript in InterSystems IRIS, specifically in CSP pages. One issue I'm running into during development is that the browser keeps loading the cached version of my JavaScript files, even after I’ve made changes or recompiled the code.
I would have to clear my cache files or browser history for it to reload and work.

Is there a recommended way or best practice in IRIS to automatically clear or bypass the browser cache for JavaScript? Ideally, I’m looking for a way to ensure that the latest version of the script is always loaded without manually clearing the cache

Hi fellow developers!

Curious if you guys use CreatedAt and LastUpdated properties in your classes?

Created to stamp when the record was created and LastUpdated when it was last updated. Where it can be useful - almost everywhere )) I find it convenient in records sorting (e.g. by creation or last update), in sync (with other systems), and so on, for better analytics.

Do you use it all the time for all the classes?

If don't, why not? What do you use instead?

What property type do you use - %TimeStamp? %DateTime?

What is the best practice to have CreatedAt filled automatically during creation and LastUpdated on every successful save (guess it could be in %OnSave)?

Please share your experience /thoughts?

The below code is not working. its unable retrieve Record count and merge files

Class Util

{

ClassMethod zPyRecordCount(inputfile) As %Integer [ Language = python ]

{

    import pandas as pd

    import iris

    import io

    try:

        df = pd.read_csv(inputfile, sep='|')

        recordcount=len(df.index)

        sys.stdout.write(len(df.index))

        return recordcount

    except Exception as e:

        return 0

}

ClassMethod zPymergefiles(file1, file2, outputfilename) As %Boolean [ Language = python ]

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... and it

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 this?) By fixing I mean I want IRIS to don't care about the case JSON fields

Thank you community for translating an earlier article into Portuguese.

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:

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 :

I'm trying to open a TCP connection to a remote system.

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.
