#InterSystems IRIS

Good morning dear community,

This is like my first post in this community. Let's see how this turns out.
I have a question about the Intersystems Kubernetes Operator and the deployment of the webgateways.
I am responsible for the hosting and deployment of the apps. For the future we are planning to host our application in a kubernetes cluster. I am using the IKO for this.
I am using webgateways, for external access as separate pods. And sidecar containers for internal access, like the management portal.

My current Problem is the configuration of the webgateways.

I use the following code to calculate the SHA1 of a file :

set stream = ##class(%Stream.FileBinary).%New()
do stream.LinkToFile(filename)
write $SYSTEM.Encryption.Base64Encode($SYSTEM.Encryption.SHA1HashStream(stream))

This code is called thousands of time and performance is critical. I have tried to code same logic in another language (which is lower level) and it's almost twice as fast. It's unclear why so I started investigating.

Using Process Monitor, it shows that files are read in chunks of 1024 bytes (1K) which is suboptimal. Reading a file of 1MB while require 1024 file system calls.

Hi Guys,

I'm a newbie in Dockers & containers and trying to install IRIS & VS Code in a container with dockers in Linux.

My understanding is that I first need to install docker, create a container then install IRIS image and looked into this documentation (Container How-to | InterSystems IRIS Data Platform 2024.2) and got me lost so I guess I need baby steps:

So I've installed Ubuntu in my Desktop and went to https://containers.intersystems.

I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.

Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?

Thanks

Scott

Hello,

While doing research on the upgrade to InterSystems IRIS 2024.1.2 version, I was wondering if it would be possible to rollback the installation and return to the previous version in case something went wrong ?

I didn't see anything talking about this in the documentation and when I tried to re-install an older kit over an upgraded instance, I couldn't use it.

Thank you in advance for your reponse

Speeding Up Antibiotic Resistance Detection with InterSystems IRIS

Antibiotic resistance is a critical health challenge, requiring rapid detection to inform effective treatments. We worked on developing a solution that leverages InterSystems IRIS vector database technology that would quickly identify resistance genes in DNA.

How It Works

Using vector embeddings, DNA sequences are transformed into numerical representations that capture essential genetic information. InterSystems IRIS then enables high-speed searching and matching of these vectors, identifying possible resistance genes.

Hello all,

We have our system with AutoParallel enabled:

USER>w ##class(%SYSTEM.SQL.Util).GetOption("AutoParallel")
1

But whenever I try to run any sql the autoparallel does not work. For example, this simple query:

When I force it with %PARALLEL we can see it will effectively run in parallel:

The total records is bigger than the threshold. So, what can go wrong? Anyone in the same situation?

Hi Guys,

We are planning to move our system from windows to Linux and I never used Linux before and all I know that is another operating system, so the new server has Linux which looks like just terminal session like Dos and as I ran "uname -r" command to check for the version in it shows some like "6.1.112-124.190.amzn2023.x86_64".

So for the available IRIS distribution and can only found versions for Ubuntu and Red Heat, so do I have to either install one of them to be able to install & run IRIS?

How to create an ODBC connection on your native Windows laptop to IRIS running on a Windows VM on the same computer, test the connection, and pull data from IRIS into Excel.

Recently I learned that Excel can connect to external databases via ODBC. This includes basically any ODBC data source. Since IRIS speaks ODBC via the ODBC API, we can take advantage of the InterSystems ODBC Driver to establish an ODBC connection to IRIS on Windows that Excel can utilize.

Is there a way to create and establish DICOM Association with Extended Negotiation? 

I have implemented DICOM Query/Retrieve C-FIND, using EnsLib.DICOM.Operation.TCP and EnsLib.DICOM.Process base classes. My application, acting as an SCU, needs to query by Study Date-Time (combined date-time matching) range with timezone query adjustment. For this, I need to use Extended Negotiation.

I've checked the IRIS Manual - Creating DICOM Associations section but there is no mention of this.

The IRIS Installation Guide for Linux, Installation Directory section, says "Do not choose the /home directory, any of its subdirectories, or the /usr/local/etc/irissys directory." but there are no suggestions or any default.

What are your opinions on this? For example, I see that IRIS in a Docker container is installed in /usr/irissys. I'm wondering why that directory was chosen.

The official Linux filesystem docs say:

• /usr is the second major section of the filesystem. /usr is shareable, read-only data.

InterSystems FAQ rubric

By default, the order of columns in a table is determined automatically by the system. To change the order, explicitly set the order for each property using the property keyword SqlColumnNumber when defining the class.

Example:

Property Name As %String [SqlColumnNumber = 2];

Please see the documentation below.

SqlColumnNumber

If you want to change the SQL table name, specify SqlTableName. If you want to change the column name (field name), specify SqlFieldName.

Both apply only to persistent classes.

Hi,

A customer today asked whether we could offer anything like the nice lineage charts that dbt offers, based on SQL view metadata. They are very much aware of our dbt-iris adapter, but were asking in the context of their landing area, which combines foreign tables and views, ahead of possibly using dbt for onward transformations.

I just restarted an AWS instance that have been dormant for 6 months (license still valid) only to find that the web application on there doesn't work and that I cannot connect to the management portal. I can however connect to the web gateway fine but it reports the "Server is currently unavailable". 

Grateful any for any advice.

Good morning,

We frequently have the "Update" button that activates when launching scheduled tasks in our feeds.

This prevents the flow of this launch at the scheduled time. See image below

Hello everyone, 
so lets say i have the following:

Hello
Q
say(arg)
    w arg
 Q

and i am trying to execute it by its name such as:

s a = "say^hello"

*execute the name inside a*
 

now I know for a fact that if say were written without any argument then do @a would work!

but I can I pass an argument in this case?
I don't want to use Xecute because I am in need of really high performance code.
 

I'm having an issue with sending SMTP requests from a specific Microsoft 365 account to Gmail accounts. We can use other Microsoft 365 accounts, but something about this one specific account sending to Gmail fails. The error we get is just telling us that sending to the user xxxxx@gmail.com failed. In order to troubleshoot that, I'm looking for more detail than that.

I see %Net.SMTP objects have a Debug property, but when I set it to 1, I can't see anything happening differently. What does that debug value do?

I assume IPM manifest tag UnitTest is tightly coupled with the standard unit test framework, right? However we have our own one that predates the standard one and we are not going to switch.

I think I need to import the unit test cases and then be able to run a single class method for the test run. Any ideas how this would be possible?

Hello,

Is there a programmatic way (in ObjectScript) to determine if a string is an SQL reserved word (aside from using embedded SQL to try to name a property with that string and look for the error :-))?

Thank you,

Jean

Hi Community,

I want to share with you the lastest app that I have uploaded to the Open Exchange "IrisGoogleChat". 

IrisGoogleChat is a utility for InterSystems IRIS that allows seamless message integration with Google Chat using Cache ObjectScript. This application provides a set of tools to configure Google Chat Channels, create messages powered by moods generated with AI and send them to a Google Chat Channel.

In order to provide the desired mood to your messages you will need an API key and an organization ID of OpenAI Chat GPT.

Is it some certain class, method, global, api, application or neither? If the entity is some of this what is the syntax?
 

🌍 Inclusion & Innovation in Education 🌍
Our project reimagines learning for all students, with a focus on accessibility and interactive experiences. Built with the goal of making education engaging and inclusive, the tool is designed to support students of all abilities in learning complex material in an intuitive way.

If you like Java and have a thriving Java ecosystem at work into which you need to incorporate IRIS, it's not a problem. Java External Language Gateway will do it seamlessly, almost. This gateway serves as a bridge between Java and Object Script in IRIS. You can create objects of Java classes in IRIS and call their methods. You just need a jar file to do this.

Hi guys,

Is it possible to apply business rule on a XML without Schema?

Say, I'm trying to make some business rules on FHIR XML payload. I transferred the XML stream as an EnsLib.EDI.XML.Document in a BPL and passed it to a General Business Rule.

 Set context.xmlDocument = ##Class(EnsLib.EDI.XML.Document).ImportFromLibraryStream(##class(HS.SDA3.QuickStream).%OpenId(request.QuickStreamId))

I'm handling following XML document 

With this rule

Then I got stuck at visiting the elements in the XML.

I.e How may I evaluate the profile value？

Thanks。

Hi everyone, 
I am new to "git-source-control", what i am doing so far will explain you in few steps.
1. installed git-source-control into a namsapace TEST using ZPM "install git-source-control"
2. configure the git settings and created a new mapping for as such 

3. Now when I am trying to ADD a new file which is created for eg - NewFolder/impl.cls , getting an error like this

exporting new version of NewFolder.impl.cls to /Users/abc/workspace/NewFolder/impl.cls

No mapping with a matching path found for file NewFolder/impl.

Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.

Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.

After some time, we stumbled upon the GetMutableSegmentAt and GetSegmentAt methods and plugged the mutable method in its place and what do you know, it worked!

Hi Guys,

I'm helping a partner to integrate IRIS to their project. They want to integrate Rules in there system.

For testing I built a simple rule as below:

/// 
Class Test.TestRule Extends Ens.Rule.Definition
{

Parameter RuleAssistClass = "Ens.Rule.GeneralBusinessRuleAssist";

XData RuleDefinition [ XMLNamespace = "http://www.intersystems.com/rule" ]
{
<ruleDefinition alias="" context="EnsLib.HL7.Service.

I am developing a business operation that receives a request, creates a message with the data contained in it and sends it to an outlook email. For testing purposes both the sender and the destination are the same email account
This is the code:
ClassBO.AlertEmailSenderExtendsEns.BusinessOperation{

Has anyone successfully tested the new THROUGH command in IRIS 2024.2 with a FOREIGN SERVER?https://docs.intersystems.com/iris20242/csp/docbook/Doc.View.cls?KEY=RS…

I have connected from a Docker instance to a VM. I was able to successfully set up the JDBC connection through the UI.

I then configured a foreign server with this connection:

But I am unable to send a SQL 'THROUGH' to the DB. I always get a:

I've get the same message if i try it via Management Portal.
I've also tried this:

and this

Always with the same error.
