Hello everyone,

I am attempting to enable two-factor authentication for a user account through the System Administration > Security > Users > Edit User (Security Settings) section. However, I am encountering an error with the Qrcode class.

ERROR #5002: ObjectScript error: <NOTOPEN>zGenerate+27^%SYS.QRCode.1

Update:
I tried to create a QR code image using the command from the %SYS.Qrcode class, and I encountered the same error. I believe it may be related to folder permissions, but I have already granted all the permissions that I am aware of to the InterSystems database.

Has anyone encountere

Let's do a round of code golf! Last one was very popular!

The Chinese zodiac is a repeating cycle of 12 years, with each year being represented by an animal and an element that changes every 2 years.
The animals are: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig.
The elements are: Wood, Fire, Earth, Metal and Water.
Your task is to write a function that receives a year, and returns the element and the animal that year represent.
Let's use the year 1924 as start point, in the Chinese zodiac the element was Wood and the animal was Rat.

Hi,

An exception occurs randomly. I expect the value of ^TEST to be 20, but it's not. Did i miss something like closing, flush the stream or locking the global?

Hello,

One of my students experiences a problem these last couple of days with downloading IRIS for MacOS. She gets this error message:

Where/how can she download it?

I've written a stored procedure for SQL as follows. The second parameter is a search path that may use a single quote or bracket as part of its expression.

When the expression uses a single quote, I can double it within SQL, and it works well. In this example, 'testDate' is written as ' ' testDate ' ' .

Select HISOL_MEAS.SQLProc_JSONpath(fullAnnotation,'HbA1cTests.sort(''testDate'',false).resultValue') As reverseSortedTests

In the next example I'd like to use brackets (see below), which causes an error.  

Trying to escape the bracket by doubling it still produces an error.  Any sugge

Does the Version of the Web Gateway have to match the version of IRIS that is currently running? Or are they independent of each other since they are different components? I am looking to install the Web Gateway (non-PWS) as we move forward with securing our Management Portal and VS Code connections using TLS.

Thanks

Scott

This article is a simple quick starter (what I did was) with SqlDatabaseChain.

Hope this ignites some interest.

Many thanks to:

sqlalchemy-iris author @Dmitry Maslennikov

Your project made this possible today.

The article script uses openai API so caution not to share table information and records externally, that you didn't intend to.

A local model could be plugged in , instead if needed.

Hi Community,

We're excited to share with you the recording of the next webinar in the series of InterSystems UKI Tech Talk:

👉 Analytics Capabilities using InterSystems IRIS 👈

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Error:

PHP Fatal error:  Uncaught PDOException: SQLSTATE[SL009]: <<Unknown error>>: [unixODBC][Driver Manager]No columns were bound prior to calling SQLFetch or SQLFetchScroll (SQLFetchScroll[0] at /builddir/build/BUILD/php-8.1.20/ext/pdo_odbc/odbc_

InterSystems will end support for using the VxFS filesystem with InterSystems IRIS and label it as deprecated as of the release of InterSystems IRIS 2023.3.  InterSystems will continue to support any existing customers using the technology, but it is no longer recommended for new deployments.

VxFS had only been supported on SUSE Linux.  Impacted customers are encouraged to migrate to XFS or another supported filesystem.

Customers with questions should reach out to their account team or contact me directly.

InterSystems FAQ rubric

Information on properties defined in a class can be obtained using the following system classes:

%Dictionary.ClassDefinetion

%Dictionary.PropertyDefinition

The code description example is as follows.

Class ISJ.Sample
{
ClassMethod getPropInfo(classname As %String)
{
    set cls=##class(%Dictionary.ClassDefinition).%OpenId(classname,,.status)
    if $$$ISERR(status) {
        write "Specified class does nt exist",!
        quit
    }
    set x=cls.Properties
    for i=1:1:x.Count() {
        // Get property info (%Dictionary.PropertyDefinition)
    

Following the documentation to insert into tableA from tableB in the SQL query box from the Management Portal :

INSERT INTO tableA (col1, col2)
SELECT col1, col2
FROM tableB

This straightforward query raises the following error :

Error #5475: routine compilation error : %sqlcq.TESTuNAMESPACE.cls305. Errors: %sqlcq.TESTuNAMESPACE.cls305.cls
ERROR: %sqlcq.TESTuNAMESPACE.csl305.1(14) :

*mt("f", "1^TABLEA") :

Could someone help me decipher this error message ? Thanks for your help.

I have a sub class that calls a method in the parent class it is derived from.

However in the below code a <NO CURRENT OBJECT> error is thrown.

Set propertyValue = $PROPERTY($THIS,name)

Using the debugger  I can see $THIS is returning the name of the subclass as it should and name is the correct property name (worth noting some properties are defined in the superclass not the subclass).

Why is this error ocouring and how can I fix it?

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD
• Why containers?
• Containers infrastructure
• CD using containers
• CD using ICM
• Container architecture

In this article, we would talk about building your own container and deploying it.

I was attempting to find a solution to grant clients anonymous access to certain API endpoints while securing others within my REST API. However, when defining a Web Application, you can only secure the entire application and not specific parts of it.

I scoured the community for answers but didn't find any exact solutions, except one recommendation to create two separate web applications, one secured and the other unsecured. However, in my opinion, this approach involves too much work and creates unnecessary maintenance overhead. I prefer to develop my APIs spec-first and decide within the spe

End of support for CentOS

CentOS will no longer be a supported development platform as of the release of InterSystems IRIS 2023.3. 

CentOS had been a supported development platform to give developers a free-to-use equivalent to Red Hat Enterprise Linux (RHEL) for IRIS development.  As you're probably aware, Red Hat made significant changes to CentOS which moved it to being “upstream” of RHEL. This means it has bugs & features not yet included in RHEL, which can cause problems for developers building on the platform.

Developers using CentOS are encouraged to take advantage of Red Hat’s free

Hi Friends,

We have a requirement to read pdf text in ensemble object script code. As object script doesn't have direct solution , i tried to implement python code , but

iris 2020 , there is no support for python in object script.

so I have found one java utill using pdfbox api.

Now I have created jar and want to register into iris and want to make a call to mymethod to read pdf text.

please help me to way forward to achieve it.

Effective documentation is a cornerstone of software development, aiding in code comprehension, maintenance, and collaboration. By harnessing the power of Doxygen and the ObjectScript filter I've created, you can generate rich static documentation from your source code. This approach does not require a running IRIS instance and thus is a good choice in situations when access to IRIS is not possible. Static documentation may be provided to end-users as-is, together with the source code.

Introduction

I searched through the community to find solutions targeting static documentation generation b

Hello Community,

I got the below error while creating a new database.

Hello Community,

I've enabled the JWT Authentication in my web application. I invoked the /login page to get the JWT and it creates an entry in %SYS.TokenAuth table. Is there any time span for the entries will rid out from the table automatically or It's  a manual process? Where can I find the JWT signature private/public key
