InterSystems announces its fourth developer preview, as part of the developer preview program for the 2023.1 release. Many updates and enhancements have been added in 2023.1 and there are also brand-new capabilities, such as production-ready support for Columnar Storage, ability to use Bulk FHIR, and support to MacOS 13 Ventura. Additionally, a new feature to provide the ability to use Foreign Tables is being released as "experimental" and will be accessible through an Early Access Program (EAP). Some of these features or improvements may not be available in this current developer preview.

Get certified on InterSystems CCR!

Hello Community,

After beta testing the new CCR Technical Implementation Specialist exam, the Certification Team of InterSystems Learning Services has performed the necessary calibration and adjustments to release it to our community. It is now ready for purchase and scheduling in the InterSystems certification exam catalog. Potential candidates can review the exam topics and the practice questions to help orient them to exam question approaches and content.

One of the reasons why I love Cache and Iris is that not only you can do anything you can imagine, also you can do it in a lot of different ways!!.

Imagine that you have an integration running with IRIS connected by ODBC you probably only run SQL queries but you can also create stored procedures and inside write the code to do everything you can imagine.

I'm going to give you some examples but the limit is your imagination!!

You might wonder, wait! I don't know how to create a store procedure in IRIS.

Goodday,

I would like to Validate token signature with public key i have in pem format, i am using below  code but i get error message. Could you please tell me what i am doing not right? FOUT #5002: Caché fout : <DIRECTORY>zLinkToFile+2^%Stream.FileBinary.1 *-----BEGIN PUBLIC KEY-----

    Do tFile.Close()
    Set tStatus=tFile.Open("RU")
    $$$ThrowOnError(tStatus)
    Set tPublicKey=tFile.Read()

Hi folks!

Lately (maybe last 2-3 years) I develop with IRIS exclusively in docker - so iris instance I use for compiling and running IRIS apps is local.

And most every time I enter password for management portal and web-apps. The same password every time. Sounds familiar?

Is there an easy way to have a parameter in docker build  for a "dev-mode" that will not ask me a password?

Is there a command that will loop through the flat files of a given Linux/Unix folder?  I can write the code to open and read each file. But the file names are unknown. I am looking for a way to access each file given a named Linux folder. The files have differing structures so a record map will not work.

Thank you for reading and thank you even more for answering!

Hey Community,

Tired of entering login-password during the docker build with your InterSystems IRIS every time?

There is a handy way to turn it on and off – use the passwordless zpm module.

Watch this video to explore how to use the passwordless ipm module to turn on and off entering login-password during docker build with your InterSystems IRIS:

I have experienced that my iris server is gone due to upgrading the docker version when I have built IRIS server on docker container.

Based on this experience, I'd like to show you how to make a backup for the IRIS server before upgrading platform or docker, and the procedure for rebuilding the IRIS in a new environment.

###IRIS server backup procedure

When you have finished building for the IRIS server, you need to make a backup.

I recommend you that you make a backup before upgrading if you have classes,routines and globals that you want to take over when you rebuild your environment.

When I run my IRIS in a Docker Container I know the host an know the mapped ports
so access is no problem.

BUT: is it possible from my IRIS
- inside a Container
- 'inside' Docker
to find the actual IP address of the Host?
This may sound strange, but for error tracking, it could be quite important.

I am looking into creating a ZSTOP as you probably have seen from my previous posts, is there a way to capture the type of shutdown that occurred? So say if there was an unknown hardware failure (forced), vs a user shutdown? Mainly looking for user or system shutdown when we force another destination to become the primary in the mirror. So if a user shutdown the production to do.,... Task A, Task B etc..

Thanks

🐞🐛▶ There is a helpful tool which allows us to debug code visually with different colours.

I found a package on OEX for a Sharding Demo
If Sharding is NOT included in the Community License
I can not use the Community Distribution but require a different one.
And have to add ZPM manually. 

To prepare a migration to IRIS I use Docker images.
The (aged) application is built around Caché Terminal
And on Windows,  IRIS uses the same ctelnetd.exe as Caché.

In my Docker installation, Telnet Settings are just grayed out in SMP.
and my Terminal can't 'connect.
Port mapping is OK and verified with TCP

Working from the console in Docker  with the whole set of ESC and
screen formatting is not acceptable.
We tried WebTerminal but there is just no Partition behind as in Terminal.

How can I switch on Telnet support in the Docker image?
 

Hello,

I want to generate and return an http response based on the input of a http GET request. For my first steps I used an EnsLib.Http.GenericService, which uses an EnsLib.HTTP.InboundAdapter to receive requests like http://[my server]:[my-port]/some-path?ID=12345678.

On the inbound side I receive a EnsLib.HTTP.GenericMessage Object which contains the parameters and some other useful information that I can work with. What I would like to do now is to create a simple HTML page, which contains some Information specific for the given parameter values.

Hi Every one

I'm working on how to use SOAP with my API and StoredProc.

Currently, the method I use is csp page to be able to get pamater from external website and Call my StoredcProc
Step 1 Get pamameter from external site
Step 2 Run My Storeproc
Step 3 Return JSON format

How to create soap and call StoredProc function from external website?

Hi all,

When I run the ^SystemPerformance utility to collect performance data about my IRIS instance (community), it manages to collect all sorts of data except for data related to ^perfmon. I am using %SYS to run the utility which should have all privilages, not sure what's meant by the below error message

perfmon

Command failed to run.
Error response from 'logman' command:


Error:
Access is denied.
Try running this command as an administrator.

Thank you!

Released with no formal announcement in IRIS preview release 2019.4 is the /api/monitor service exposing IRIS metrics in Prometheus format. Big news for anyone wanting to use IRIS metrics as part of their monitoring and alerting solution. The API is a component of the new IRIS System Alerting and Monitoring (SAM) solution that will be released in an upcoming version of IRIS.

However, you do not have to wait for SAM to start planning and trialling this API to monitor your IRIS instances.

Hi  

Is there any build in solution to convert HTML to PDF?  if yes please how

Thank you

InterSystems announces its third developer preview, as part of the developer preview program for the 2023.1 release.

Future preview releases are expected to be updated biweekly and we will add features as they are ready.

Introduction

This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too.
I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.
I'm going to use the sample data created in a previous article, Quick sample database tutorial: Samples.PersistentData, with the properties Name and Age.

InterSystems is pleased to announce the 2022.3 release of InterSystems IRIS Data Platform, InterSystems IRIS for Health, HealthShare Health Connect, and InterSystems IRIS Studio are now Generally Available (GA).

2022.3 is a Continuous Delivery (CD) release. Many updates and enhancements have been added in 2022.3, in SQL management, cloud integration, Kafka and JMS adapters, the SQL Loader, and other areas. The new FHIR SQL Builder and enhancements to Columnar Storage are included, but both are still experimental features (not for production, with an active Early Access Program in place).

I use the following query to get a list of all classes : 

select * from %Dictionary.ClassDefinition 
where System=0 and Hidden=0 

It works, but AFAIK it return all classes from all namespaces, including the ones defined in %SYS (usually classes they starts with % like %CSP).

I would like to get only classes of current namespace. I have checked all the columns returned by the query and none allow to filter on a given namespace.

The solution I am looking for does not need to be a query, the query I posted above is called from code.

I am working on setting up our Failover techniques as we move to a Mirror Environment with a Arbiter, 2 Failover Nodes, and a Async (DR) Node. There are some system commands that I would like to call when the Mirror moves, and I am working on a ZMIRROR routine for that, but I also wanted to create an additional step if we wanted to manually shutdown and for the Mirror to move. So I was looking at using ZSTOP to call a couple of different items while shutting down, while the documentation has an example a couple of questions come to mind about using ZSTOP.

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ InterSystems Deployment Options @ Global Summit 2022

Foreword

InterSystems IRIS versions 2022.2 and newer feature a redesigned functionality for JSON web tokens (JWTs). Once housed under the %OAuth2 class package, the JWT class, along with other JSON web classes (JWCs), now live under %Net.JSON. This migration occured in order to modularize the JWCs. Before, they were closely intertwined with the implementation for the OAuth 2.0 framework. Now, they can be maintained and used separately from OAuth2.

Note: For backwards compatibility, the classes still exist under %OAuth2 package, but the codebase now uses %Net.JSON.

InterSystems IRIS 2022.2 has Native SDK for Python (https://docs.intersystems.com/iris20222/csp/docbook/Doc.View.cls?KEY=PA…).

We know how to traverse a global data structure using IRIS Object Script $Order function.

SET key=""
   FOR  {
     SET key=$ORDER(^myglobal(key)) 
     QUIT:key=""
     WRITE !,^myglobal(key)
   }

How to do the same from Python using IRIS Native SDK for Python? Here is a code example:

import iris

args = {'hostname':'127.0.0.1', 'port':51772,
    'namespace':'USER', 'username':'_SYSTEM', 'password':'SYS'
    }

conn = iris.

I'm curious about how embedded Python is handled by %CSP classes, particularly in the case of defining REST endpoints on IRIS.
Here is a simple dispatch class for the endpoint /api/pythonapp on my local IRIS instance (2022.3):

Class Python.App.Dispatch Extends %CSP.REST
{

XData UrlMap [ XMLNamespace = "https://www.intersystems.com/urlmap" ]
{
<Routes>
    <Route Url="/test" Method="GET" Call="Hello" />
</Routes>
}

ClassMethod Hello() As %Status [ Language = python ]
{
    import iris

    print('Hello World!

Any ideas on why my %session.Data array would be wiped out after setting %response.Redirect in OnPreHTTP()?

Context: trying to implement a SSO patter for authorization code flow.  I mention this because it's all I can really pinpoint as to what's changing.  Typically a user logs in by providing their username/password and we validate in our database and set the %session.Data property with the user info.

Hello,

I'm starting testing embedded python and external libraries.

When I try to use the win32api-library I get the following error :

<THROW> *%Exception.PythonException  230 ^^0^ <class 'ModuleNotFoundError'>: No module named 'win32api' -

This is my code :

ClassMethod CreateDocument(path As %String) [ Language = python ]
{
import win32api

...
}
 

The librarie is visible in C:\InterSystems\IRIS\mgr\python\win32.

Am I doing something wrong ?

Hi Friends ,

We have requirement to load data into chache tables from external database (ref data). This process will take 1 min to complete all data load.

Currently I have created Business Service  to trigger Business Operation with out bound db adapter to load data into cache tables.

process will be trigger when i restarted business service.

But requirement  is  , this business service should be triggered from outside ensemble environment i.e , this should expose as REST endpoint and share with the external team.

How to expose Business service as REST endpoint? I need help for this regard.
