Migrate to VS Code this summer with our comprehensive Basics and Advanced Features training courses.

George James Software is offering migration strategies and training to support the adoption of VS Code with InterSystems IRIS, IRIS for Health, HealthShare, and Caché. We're in the unique position of having deep knowledge and understanding of both InterSystems platforms and VS Code, through our regular contributions to VS Code itself.

InterSystems FAQ rubric

If you do not specify the option to remove the mirror attribute of the mirror database when deleting the mirror configuration, the database cannot be restored to a normal state and will be mounted read-only the next time it is mounted. To restore the database to a read-write state, you must remove the mirror attribute using the system routine ^MIRROR.

The procedure is as follows (execute in the %SYS namespace):

Using Two-Factor Authentication

Introduction

If the administrators responsible for securing applications had their way, passwords would be long complex strings of random symbols, and users would memorize different passwords for every application they use. But in the real world, few people are capable of such prodigious feats of memory. The typical user can only remember a handful of relatively short passwords.

Error Compiling class

Hi,

ERROR #5002: Cache error: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
> ERROR #5030: An error occurred while compiling class 'ClassNameHere'

Is there anything I can do to fix this issue?

Thank you in advance for your response.

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.

Presenter: Murray Oldfield
Task: Avoid bottlenecks caused by scaling up, before they become a problem
Approach: Discuss what operating system and InterSystems metrics you should look at and how to interpret them

Systems behave differently when database activity scales up. In the worst case, bottlenecks appear and users are impacted. This session shows you which operating system and InterSystems metrics you should be looking at and how to interpret them so you can head off bottlenecks before they impact users. This sessions also shows strategies for planning infrastructure taking into consideration InterSystems' data platforms requirements.

Content related to this session, including slides, video and additional learning content can be found here.

Atelier, The XML Contents Editor

This article is one of the series which introduces Eclipse to experienced Caché/ Ensemble/ HealthShare users. The goal is to open the perspective of a developer who was using Caché Studio for years and make Her/ Him see deeply into the Eclipse world – far beyond Atelier. In other words it is an Atelier (Eclipse IDE for InterSystems technology) beginner’s guide. This time the topic is: editing XML files using Atelier.

Part 3. Appendix

InterSystems IRIS OAUTH classes explained

In the previous part of our series we have learned about configuring InterSystems IRIS to act as an OAUTH client as well as authorization and authentication server (by means of OpenID Connect). In this final part of our series we are going to describe classes implementing InterSystems IRIS OAuth 2.0 framework. We will also discuss use cases for selected methods of API classes.

The API classes implementing OAuth 2.0 can be separated into three different groups according to their purpose. All classes are implemented in %SYS namespace. Some of them are public (via % package), some not and should not be called by developers directly.

Hello again and welcome to the next tutorial on this series: Part 4 - Sharing data across router methods. Here we are going to learn how to share a object containing data that is available for read across every router methods.

You're required to complete at least the Part 1 before entering this one. Still, this is supposed to be a really short tutorial, since there isn't much to be said about data sharing.

InterSystems has corrected two defects that, in rare circumstances, can result in data integrity corruption after running global compaction, database compaction, or database defragmentation. InterSystems recommends avoiding these utilities until after applying the corrections listed below.

gj :: locate was the entry from George James Software for the Developer Tools competition back in April 2021. When an ObjectScript error is reported, gj :: locate takes the .int line location and navigates you directly to the line in the source file where the error originated. Over the past few months we've found it a very useful tool when it comes to debugging, especially when used alongside the Serenji debugger in Visual Studio Code.

Our first update, version 1.1.0, now includes support for multi-root workspaces. This enables gj :: locate to be used with every workspace folder. If your VS Code workspace has more than one root level folder, connecting to different namespaces or perhaps different servers, then gj :: locate will determine which workspace folder is current and locate the source code in that folder. If your workspace doesn't have any files open then gj :: locate will prompt you to select a folder from a pick-list.

This will particularly benefit VS Code power users who have workspaces with simultaneous connections to multiple namespaces, on multiple different IRIS and Caché servers.

If you would like to try it out then you can download it from the VS Code marketplace. Or if you’re already a user, then gj :: locate will automatically update. Let us know how you're getting on with it!

Hi,

I have wrote an article about how to install the intersystems cache driver in a Docker container, and then deploy it using Azure Functions:

How to run a (Python) Azure Function as a Docker container & Deploy it using Bicep | Victor Sanner

This might be useful to others, especially the dockerfile which I have copied below. This builds a debian docker container and installs the Intersystems Cache driver, which python can then use :)

Client Websockets based CSP

The Caché / Ensemble standard distribution contains in namespace SAMPLES
a nice example of a CSP page consuming WebService as a Client.
I have modified it not only to display the replies but to feed them back into a Global.
I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY.
When there is no input anymore the page closes and goes away.

There are 2 versions with visible and hidden display during operation.
dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls

We've implemented SAML authentication for our application where we are the service provider and various other entities are the identity providers. We've done successful connections with several identity providers including Okta, Duo Mobile, Ping Identity, and Azure. Validating the SAML response with signed assertions has been working great. Now, I am trying implement support for the SAML assertions in the response being encrypted for a new identity provider and struggling to understand procedurally how to go about this.
