One way to optimize query performance is to use query parallelism on a per-query or system-wide basis (a standard feature).

This is a technique for dividing the execution of a particular query among processors on a multi-processor system. The query optimizer will execute parallel processing only if there is a possibility of benefiting from parallel processing. Parallel processing is only applicable to SELECT statements.

Hello Community!

We're excited to announce that the FHIR France Meetup is making a comeback... in person at SantExpo 2025!

📅 Dates: May 21, 2025, starting at 7:00 PM

📌 Location: Halles d'Issy - Biltoki, 1 Rue Rouget de Lisle, Issy-les-Moulineaux, Paris, France

Hi developers!
Happy holidays!

In ObjectScript there is neat option to log errors - call Log() method of an exception intance, e.g.:

ClassMethod MyMethod() {

Try {

w 1/0

}

Catch e {

do e.Log() // logging error in the app log

write "the error happened: "_e.DisplayString()

}

}

Is there anything like that for Embedded Python? e.g:

ClassMethod MyMethod() [Language = python] {

 try:

   print(1/0)

 except ZeroDivisionError as e:

   // how can I log e into IRIS App Error Log here?

   print("Caught exception: " + str(e))

}

Any ideas?

Hi Community,

Are you a Python developer? If so, you can already start building apps with InterSystems IRIS without learning a new programming language!

Hi Everyone,

So after @Ariel Glikman posted a custom operation example, I'm stuck on another dilemma, and here it is:

Hi, I'm wondering what are the diferences between a method or classmethod with the language set at tsql and a querry writen in sql.
If anyone know if there is some difference and what they are, I would be glad to learn. 😊

Are you attending InterSystems READY 2025 (June 22–25), this year's global summit?

Hey Developers,

Not sure where to ask for some helpful hints about IRIS 2019.1 in 2025, but here goes.

I'm trying to create a new Java gateway to run some Java code through ObjectScript, but I keep getting an error saying "Java executable not found in the given directory":

This is my Object Gateway Server definition:

I cloned iris-rag-demo from Open Exchange and issued docker-compose up -d. I went to the front end and type in the chat message:

Who was the 46th President of United States of America?

I got a run time error:

RuntimeError: ERROR <Ens>ErrBPTerminated: Terminating BP ChatProcess # due to error: ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'RuntimeError'>: <PYTHON EXCEPTION> <class 'ValueError' > ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'RuntimeError'

Traceback:

Does %OSCertificateStore only check the trusted root folder in windows?

Can it be used for Personal store on servers or is there another condition can be used?

Used it for a first time and writing a function to check specific ones being used for expiry but had one this week that was to be installed in personal rather than the trusted root and didn't know if stating OSCertificateStore or a url otherwise to look in the personal installed certs on the server could be used instead so stuck with the original way (which can get confusing)

For developers building external applications, especially those using familiar technologies like C#, ODBC (Open Database Connectivity) is a crucial, standardized bridge to any relational database, including InterSystems IRIS. While InterSystems offers its own native ADO.NET provider, the ODBC driver is often the most straightforward path for integration with generic database tools and frameworks.

Here is a step-by-step guide to getting your C# application connected to an IRIS instance using the ODBC driver, focusing on DSN-less connection string.

Step 1: Install the InterSystems IRIS ODBC Driver

The InterSystems ODBC driver is installed by default when you install InterSystems IRIS on a Windows machine.

• If IRIS is on the same machine: The driver is already present.
• If IRIS is on a remote server: You must download and install the standalone ODBC client driver package for your client operating system (Windows, Linux, or macOS) and bitness (32-bit or 64-bit) from WRC website if you're a client or by installing Client components and copying ODBC driver.

Once installed, you can verify its presence in the ODBC Data Source Administrator tool on Windows (look for the InterSystems IRIS ODBC35 driver).
