InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Hi All,

We're doing our first babysteps with embedded Python and IRIS with an interoperability solution. We want to convert a CSV file to an Excel xlt file.

As service we've got a EnsLib.File.PassthroughService which picks up a csv file

As operation we've got a EnsLib.File.PassthroughOperation which writes the Excel file.

In the middle:

We've created an Business Process with an %Stream.GlobalCharacter in the Request and a %Stream.GlobalCharacter in the Response.

Hi!

Currently, I'm working on a script using %SYS.Journal API.

My journal files are compressed, following the documentation the compression is zstd.

I tried to unzip a file with zstd tool, ex: 

apt-get update
apt-get install zstd

zstd -d 20230806.001z -o 20230806.001

20230806.001z        : 92.03%   (909312 => 836859 bytes, 20230806.001)

Unfortunately, the unzipped file is invalid:

Write ##class(%SYS.Journal.File).IsValidJournal("/usr/irissys/mgr/journal/20230806.001")

There is several classes that allow to create TCP/IP connections (eg: to connect to a service).

Example : %Net.FtpSession (port 21), %Net.HttpRequest (usually port 80 or 443)

AFAIK connection will stay open unless closed explicitly or if variable that hold the instance is garbage collected.

Is there a way to get a list of all active (open) TCP/IP connections IRIS is maintaining so far ?

Hi,

I try to initialize some properties of a %DynamicObject during his creation.

I Try to use InitialExpression this way :

Property refDate As %Date [InitialExpression = $piece($horolog,",",1)];

But it doesn't compile

I don't found if %DynamicObject can have a constructor to initialize properties by a calculated value, like other languages.

Hi,

Using Interoperability, I can't figure out how to create separate XML's files from a CSV-file using the GUI-features Record Maps/Complex Record Mapper -> Data Transformations. I'm familiar with reading/writing the files using File Service/Operation, but don't understand the processing-steps.
The preferred method by my colleagues is to do this without any Objectscript or Embedded Python coding, but if this can only be done by some coding that's fine as well.

See example below.
Any help is appreciated!

Kind regards,
Ties Voskamp

First time setting up a SSL/TLS connection, and I am running into issues when I call it from within a Business Operation. I used openssl to generate a RSA 4096  SHA512 key/csr request for our Active Directory Certificate Service to generate a Certificate Chain for me to use within RedHat. I was 
able to connect to our Web Service server using a generic request from terminal, however when I try it from our Business Operation I am running into issues.

I tested the SSL/TLS connection using the following commands from the terminal...

DEVCLIN>set request=##class(%Net.HttpRequest).%New()

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

IRISPIP Cryptodome C++ Error

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

Class Documentation

I like to add documentation to the top of every class I write. Is there a way to modify or create a template that would automatically add the lines below to the top of the class? I primarily use Studio IDE but would like to be able to do this using VS Code as well.

Rule logic

In an HL7 Business rule I am trying to block ONLY ORM messages that have a PV1:3.4 of 105 or 205 and a OBR:4 value of EP22 or CATH01.

I created the logic below but it appears to be evaluating the two fields independently instead of combined?

Here is what I had.

Visual Studio Code, like Atelier, connects to IRIS through the Web Server and a web service, unlike Studio that connect to the SuperServer port.

What about the VS Code terminal? Does that open a shell with SSH or does it also use a web service?

In other words, does an IRIS developer using VS Code need direct access to the IRIS instance with SSH or the SuperServer port, in addition to the external or private web server to execute terminal commands?

Is that different with linux vs. Windows?

After installing IRIS 2023.1 on a live copy of our production machine our REST Service now consumes a CSP Session with every request. The request is handled as expected, but uses one of the 5 CSP Session per license. So after 25 requests, the license is used up. The Grace time always shows 0 and the session stay for very long. (Maybe the 900 Seconds timeout).
On Caché 2018, we had the same settings for the Webapp and there, only a single Session was set for all requests. The Caché request didn't use any cookies.

Hi,

I am trying to load all the data tables from one iris server to a client server but some of the tables data failing to load all the time. But I can load around 100 tables successfully but 8 to 10 tables are failing all the time. I made an IRIS odbc connection using odbc driver to load the data from tables.

Also I can see read server loop error message on the iris server side as the same time the table loading fails.

Please find the screen shot attached which shows the error on client server.

Iris DAT file is filling up the Internal Storage with available Free Space to Zero. Is there any Alternative measures to reduce the File size or to control the Capacity. Is there any chance to save Local storage.

Once the Local Storage is full, Production is not responding and throwing Out of Space Error.

Does IRIS has any Internal Cloud Storage which can be used for managing and Storing Database Operations. If yes, How can we configure it,

I am trying to setup our first SSL/TLS configuration so we can possibly connect to the EMR FHIR server to pull data into the Interoperability engine.

I am running on Red Hat, and created and submitted a openssl CSR request to our Windows ADCS system.

I used the following command to generate the key and CSR request to submit to Windows ADCS

openssl req -new -sha512 -nodes -newkey rsa:4096 -keyout xxxxxxx.key -out xxxxxxxx.csr

This is a bit of an IRIS question but also and OAuth 2.0 questions:

I am using %OAuth2.JWT.JWTToObject() to "validate" a JWT. My questions:

- While I am checking claims with the returned body, does the return status of the method "count" as a validation step? In other words, if I weren't checking claims and $$$OK was returned from that method call (passing in the token and public keys), I could feel confident that this token came from the expected auth server?

When manually coding REST services and using GET /api/mgmnt/v1/:namespace/spec/:application/ to return an OpenAPI spec, how do you specify supported properties (OpenAPI Properties in Use | Creating REST Services | InterSystems IRIS Data Platform 2021.1) like responses, definitions, and information in paths like summary and description?
