February 19, 2025 – Alert: SQL Queries Returning Wrong Results

InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.

Hi Community!

We're happy to share the next video in the series dedicated to Gen AI on our InterSystems Developers YouTube:

⏯ AI model distillation

Hello all,

We are currently developing a set of cubes in Unified Care Report (UCR) for data analysis purposes. However, we are encountering issues with cube dependencies, where certain cubes rely on others to be compiled beforehand. The complexity of these dependencies is becoming increasingly difficult to manage, particularly when attempting to deploy the cubes.

The problem arises when trying to compile a cube that depends on another cube, which may also have its own dependencies. For instance, when compiling the Test.Cube.

I am using an Apache webserver on RH8, which is working fine. However, I get the following message:

Directory /opt/webgateway/conf/temp/ does not exist or has incorrect permissions. This will limit the Web Gateway's functionality.

The folder is indeed missing, but in what way is it limiting functionality?

Hello! 
So my question is quite simple, Do the different data models of Intersystems all support the ACID properties?
I assume that for the SQL data model implementation it does, But does it also work for global (i.e the hierarchical  data model)?
I searched the docs and the different articles, It seems for example that here its implied that the different data models of Intersystems  DO indeed support the ACID properties and allow for safe insertion, deletion etc... in concurrent operations to the server that is.

Would love to get a clarification, Thx!

REST API with Swagger in InterSystems IRIS

Hello

The HTTP protocol allows you to obtain resources, such as HTML documents. It is the basis of any data exchange on the Web and a client-server protocol, meaning that requests are initiated by the recipient, usually a Web browser.

REST APIs take advantage of this protocol to exchange messages between client and server. This makes REST APIs fast, lightweight, and flexible. REST APIs use the HTTP verbs GET, POST, PUT, DELETE, and others to indicate the actions they want to perform.

Hi Community, 

I have a problem I am hoping someone can help with - I have created a front-end with HTML/CSS/JS in a CSP page in Iris Studio. I am trying to use objectscript on the back end to connect to a SQL Server Database (with valid credentials), and execute a stored procedure.

I have a fileList variable that is a stored as a comma separated string through a user input textBoxContainer.

Hi Community,

Hello Community:

Do you want to know how to record yourself without looking like you're speaking from a cave? Are you one of those who say you ‘don't come off well on camera’? 

Today I'm going to share with you some specific tips that I learned after several years of filming interviews for television and networks. I remind you that these are tips in case you are thinking of taking advantage of the Article Contest video bonus. However, they are tips that I'm sure you can use for presenting webinars, video calls and filming yourself in general.

Hey guys!

I'm working on a Java application that connects to Iris via JDBC.
I need to disable SharedMemory via connection URL.
I would like to know how I can check if the parameter was turned on or off within Iris when connecting to Java.
Thanks for your help!

Hi community,

I am having a hard time figuring out how to properly use %ZEN.Auxiliary.jsonProvider to serialize a %RegisteredObject to JSON. Would be anyone so kind to share some simple usage example?

Thanks

Hi Community,

Enjoy the new video on InterSystems Developers YouTube:

⏯ FHIR Repository and FHIR SQL Builder @ Global Summit 2024

For example we have a docker app that receives a .csv file from windows environment and then do some processing on it in docker linux environment.

Windows encode new line in CRLF format, but linux can understand only LF and throw an unexpected errors like
 

ERROR #7207: Datatype value '100 ' is not a valid number > ERROR #5802: Datatype validation failed on property 'esh.i14y.csv.CelciusCSV.Record:Temperature', with value equal to "100 "

Is there a way to convert new line logic inside iris container in cases when .csv file (and other possible files) comes from windows environment ?

Hi all!

In this article I would like to review those VS Code extensions which I use myself to work with InterSystems and which make my work much more convenient. I am sure this article will be useful for those who are just starting their journey to learn InterSystems technologies. However, I also hope that this article could be useful for experienced developers with many years of experience and open up new possibilities for them when using VS Code for development.

Hey Community,

It's time for the new batch of #KeyQuestions from the previous month.

Here are the Key Questions of January chosen by InterSystems Experts within all Communities:

For some build scripting with the InterSystems Package Manager, I'd like to first uninstall a package with `zpm "uninstall"` and then load it from disk using `zpm "load"`. That way anything that got deleted from the source will also be deleted from IRIS. 

The problem is that `zpm "uninstall"` takes in a module name and I only have the directory path to the package source. Is there a way to get the module name for an installed IPM module given the source path? It's okay  to assume that it has previously been installed from that same directory with `zpm "load"`.

Hi Community,

As you may know, this year's Spanish Technical Articles contest will be in May. I am going to make a series of articles to support you in the creation of your articles, giving tips and tricks. Perhaps they will be useful for the contest you have active in this community as well.

As you may know, one of the bonuses or extra points you can receive is to add a video tutorial to your article. You may not even know how to approach this issue, no problem! I'm here to give you some tips that you can apply not only to the creation of these videos, but to any other.

I have an Iris Intersystems instance that works with Apache server  on Windows 11 machine. Are there any clear and simple instruction or documentation  that explain how to migrate from Apache server to Nginx server?

Hi beloved members of the Community!

It is very common in the daily life of IRIS or Health Connect users that it is necessary to install new instances or update the ones they already have and in many cases it is not these same users who carry out the installation, but rather systems personnel who often do not take into account the particularities of the assignment of permissions necessary for the installation.

Hi,

I running an SQL so I can find the databases with the largest amount of free space. This is in case I can compact the databases.

However SQL cannot find the SYS.Database table.

Can someone please explain how to fix?

[SQL]TEST:%SYS>>select * from SYS.Database
ERROR #5540: SQLCODE: -30 Message:  Table 'SYS.DATABASE' not found

[SQL]TEST:%SYS>>  << entering multiline statement mode, 'GO' to execute >>
   1>>select DatabaseName, Directory, Size, Free, DiskFreeSpace
   2>>from SYS.Database
   3>>order by DiskFreeSpace DESC
   4>>go
ERROR #5540: SQLCODE: -30 Message:  Table 'SYS.

When debugging a routine in vscode which requires input to a READ, there doesn't appear to be any way to enter the input.  If the routine is running in a terminal with vscode attached then input can be done there, but can it be done with no attached process?

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Introduction to running WSGI in IRIS

With IRIS 2024+, users can host WSGI applications using Security.Applications. As an example, a user can do something like this

Hi all! Here I would like to share how we use vector search and GenAI with InterSystems technology. As an example, I'll describe BG-AppealAI project, which our company submitted to the InterSystems Vector Search, GenAI and ML Contest. BG-AppealAI application can write an appeal if you upload an insurance contract and the insurance company’s letter with a refusal to pay medical expenses. Of course, we are aware that at the moment AI has not reached such a level as to create ready-made legal documents.

We are trying to create a JWT in order to get oauth2 token from login.microsoftonline.com and then use that token to get key/secret from an Azure Key Vault.

It seemed like it would be quite straightforward by using the Create method of class  %Net.JSON.JWT

But already trying to set the first header parameter alg PS256 as specified by https://learn.microsoft.com/en-us/entra/identity-platform/certificate-c… becomes a problem.

Hi, this post was initially written for Caché. In June 2023, I finally updated it for IRIS. If you are revisiting the post since then, the only real change is substituting Caché for IRIS! I also updated the links for IRIS documentation and fixed a few typos and grammatical errors. Enjoy :)

In this post, I show strategies for backing up InterSystems IRIS using External Backup with examples of integrating with snapshot-based solutions. Most solutions I see today are deployed on Linux on VMware, so a lot of the post shows how solutions integrate VMware snapshot technology as examples.
