⏯ Unleash the Power of Your Data with InterSystems @ Global Summit 2024

Currently we are exploring how we can allocate additional disk space to our current environment as we have seen a significant increase in growth of our Database files. Currently we have 3 namespaces, all with 1 IRIS.dat each that contains both the Global and Routines.

Since we have started down the route of everything within a single IRIS.dat file for each namespace, is it logical as we see growth to be able to split the current IRIS.dat for each namespace into a separate IRIS.dat for global and a IRIS.dat with for routines for each namespace in a Mirror environment?

In the preceding section, we explored the installation process and initiated the writing of the IRIS in native Python. We will now proceed to examine global traversal and engage with IRIS class objects.

 get: this function is used to get values from the traversal node.

def traversal_firstlevel_subscript():
    """
    ^mygbl(235)="test66,62" and ^mygbl(912)="test118,78"
    """
    for  i in irispy.node('^mygbl'):
        print(i, gbl_node.

Hi community members!

I'm testing some functionalities about Foreign Tables and it works smoothly with PostgreSQL database, but I found out an issue with MySQL database, I followed the documentation:

• Step 1: I've created my SQL Gateway connection to my MySQL database: **WARNING** if the name of the driver file is too long IRIS won't be able to get it.

• Step 2: Create foreign server:
  

  CREATE FOREIGN SERVER Test.MySQLDB FOREIGN DATA WRAPPER JDBC CONNECTION 'MySQL'

• Step 3: Create foreign table:
  

  CREATE FOREIGN TABLE Test.PatientMySQL SERVER Test.MySQLDB TABLE 'patient'

• Step 4: Query Test.

Say I want to uninstall the IKO - all I need to do is:

> helm uninstall intersystems

What happens behind the scenes is that helm will uninstall what was installed when you ran :

> helm install intersystems <relative/path/to/iris-operator>

In some sense - this is symmetric to when we ran install - however with a different image.

You'll notice that when you install, it knows what image to take from:

operator:
  registry: containers.intersystems.com
  repository: intersystems/iris-operator-amd
  tag: 3.713.

Hello, I want to create PDF from HTML source. I found pandoc. I installed pandoc on IRIS container image. I created Interoperability production. I have setup REST service to receive HTML file in request body. I call pandoc command pandoc -o output.pdf input.html  from a BPL process. I copy output.pdf file stream into response body. I save the response at the source. I get a file named output.pdf but it does not load in Acrobat. I suspect I am doing something wrong with headers (accept-encoding?) or maybe do I need to base64 encode the pdf file to transfer it via REST?

Hello all,

On one of my team's systems, we utilize a business operation with the EnsLib.SQL.OutboundAdapter to make SQL queries to another IRIS system using JDBC. To authenticate the connection, we utilize a user account on the target system.

We recently had a failure where this user account expired due to inactivity, causing all queries to error until the account was reactivated on the target system.

⏯ High-Speed Ingestion Using InterSystems IRIS Persister with Java @ Global Summit 2023

Recently I got into a situation where a user had some roles, which granted additional roles, and so on.

As I did not understand where a particular permission came from, I wrote this code which gets an initial set of roles and unwraps them recursively, accounting for any repeats.

Hello, 

I'm working on building some .NET Scripts/CLI tools and starting to use the .NET external language server.

I've been able to connect using the .NET SDK, but trying to understand a little how to make a call that has a output parameter. I've read that you should use IRISReference, but haven't been able to get that to work. Here is what I'm trying to do
I'm trying to make a call to the %SYS.Namespace.ListAll() method but as you will note, the first param for the method is an output param (https://docs.intersystems.com/irisforhealthlatest/csp/documatic/%25CSP…?

I'm posting this for the benefit of WebTerminal users who have upgraded to the recently-released IRIS 2024.2 -- (Build 247U) Tue Jul 16 2024 09:52:30 EDT -- or are considering doing so.

That version of 2024.2 contains a change (DP-432503) which requires that the user under which the Web Gateway initially connects to IRIS (usually CSPSystem) must have READ permission on the database hosting the dispatch class of the REST web application.

For cases where that is not true an error is raised, but this returns an HTTP 404 status to the caller instead of the expected HTTP 401.

Hi, Community!

We're happy to introduce a new learning path created by the Online Learning team:

Getting Started with InterSystems ObjectScript

I have this code and I need to send 

Set tRequest= ##class(Testing.Messages.GatewayCreateFacilityRequest).%New()

Set tRequest.facilityCode ="VINUSE"

 Set tResponse = ##class(Testing.Messages.GatewayCreateFacilityResponse).%New()

need to send a request to a new server:

Server: ECR10 

Namespace: ECR

Business Service: Healthix.Common.Verato.Gateway.Service.HubQueryService

set tResponse = ##class(Testing.Gateway.Service.HubQueryService).%New().CreateFacility(tRequest)

How do I add code to send it to the ECR10 server?

FOREIGN TABLES is a rather fresh feature in IRIS  (2023.?)
So I was motivated to try something new by own hands.
Documentation of Foreign Table from File is a good starting point.
Also the related promotional video is fine to start with.

Samba is the standard for file services interoperability across Linux, Unix, DOS, Windows, OS/2 and other OS. Since 1992, Samba has provided secure, stable and fast file services for all clients (OS and programs) using the SMB/CIFS protocol. Network administrators have used SAMBA to create shared network folders to allow company employees to create, edit and view corporate files as if they were on their computers locally, when these files are physically located on a network file server. It is possible to create a network folder in Linux and see it as a shared folder in Windows, for example.

Instead of building a BP to execute stored procedures just to insert the data, I figured I would give Linked Stored Procedures a try since all I need to do is insert the data. I have proved in our MS SQL Development environment that it is possible, so I through I could just repoint the Linked Stored Procedure 

set hdbc=$$GetJConnection^%apiGTW("xxxxx")

to the test environment. But when I made the changed in VSCode and compiled the Stored Procedure disappeared from the SQL view in the Management Portal.

So can we not simply update the connection string to point to a different MS SQL Connection?

I have challenged to create a bot application using Azure Bot that can retrieve and post data to IRIS for Health.

A patient's data has already been registered in the FHIR repository of IRIS for Health.

The patient's MRN is 1001. His name is Taro Yamada. (in Japanese :山田 太郎)

This bot can post new pulse oximeter readings as an observation resource linked to the patient.

For practical reasons, it may be desirable that after a Linux server restart, the IRIS instance is automatically started. 

Below you will find the steps to follow to automate the startup of IRIS during a reboot of the Linux server, via systemd :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

[Unit]
Description=InterSystems IRIS Data Platform
After=network.

So, here is a novice question; but, I can't seem to figure out how to do it, or find any comments. I simply want to close out this DTL, under the Interoperability / Build / DTL screen:

There do not seem to be any buttons to 'close' the current DTL item. I tried logging off and back on, and, it brings it right back. Ideas?

The following code downloads https://www.intersystems.com/assets/intersystems-logo.png and saves the file as c:\temp\test.png.

You need to define an SSL configuration called SSLTEST before executing this code

ClassMethod download() As %Status

    Set sc = $$$OK
    Set httprequest=##class(%Net.HttpRequest).%New()
    set httprequest.Port = 443
    set httprequest.Https = 1
    set httprequest.SSLConfiguration = "SSLTEST"
    Set httprequest.Server="www.intersystems.com"

InterSystems IRIS Adaptive Analytics version 2024.1.3 is now available from the InterSystems Software Distribution  page.  This release includes AtScale 2024.1.3, and an updated User Defined Aggregate Function (UDAF) file.  This release includes and the following new modeling and BI capabilities:

• Formatting of calculation output based on on the field input rather than just the format defined on the calculation.  This is particularly useful for calculations that can't have a standard output format, such as year-over-year growth in dollars, euros, or time.

Hello, 
A customer whose Ensemble code contains lots of hardwired API URL calls is running into issues because of the IRIS instance name insertion in the URL path since IRIS v 2024.1.

What are the best solutions to revert to the previous URL path or automatically and dynamically rewrite this path (Apache mod_rewrite ? Proxies ?). Any examples ? 
Thanks for your help,

Is there a wizard to override pieces of class (parameters, properties, methods, etc.) like there is in Studio? I can't find this functionality anywhere. If it's not there, it's certainly a piece I'll sorely miss as we transition to VS Code.

Hello everyone,

I'm currently working on getting familiar with OAuth2, following this article. Since Part 2 involves using PKI, I decided to implement it as outlined in the article. However, I've run into an issue that I can't seem to resolve, and my searches on Google haven't yielded any useful results.

Here's a brief overview of what I've done so far:

Configuring the PKI Server:

• Navigated to: System Administration > Security > Public Key Infrastructure > Configure Local Certificate Authority Server.
• Filled in all the required fields and saved the configuration.

I use the following code to loop trough all globals : 

set name=""
for
{
   set name=$order(^$GLOBAL(name))
   quit:name=""
   write name,!
}

However this is really slow : about 1second per node. 

I ran debugger, and it seems most of the time is spend in "%SYS.GD Visible" function. There is a comment that says : 
"Sees if globals in dataset are visible to our namespace"
This function loop on a global named  ^mtemp which contains lot of records (10K or more).
I have cleared global, hoping it has been filled by another process but it's not (it seems to be filled by %SYS.
