Which process notify Web Gateway when to switch to secondary/mirror IRIS? I'm trying to debug a case when the web gateway doesn't know about primary IRIS failure and is trying to send request to that instance which is causing 500 error. Also, no clue why at the same time I see that GET request to /csp/bin/mirror_status.cxw will return 200 OK.

MIRROR for Embedded Python ?

MIRROR is the best solution for almost immediate replications to a Failover Server.
The related mechanics are based on Global Journaling.

Globals hold Data and Classes and Routines and more ...
If Mirroring is in place all is in sync. With minimum delays
This is of course rather useful for code changes in Classes, Routines, ....

To what extent is Embedded Python covered by Mirroring?
Or:
What is required to Synchronize EmbeddedPython like Mirroring.

Hi developers, 

Serenji 3.2.0, the latest version from George James Software, was released last week and our current users have been enjoying trying out the new features (which you can find more about here). 

If you're thinking about trying Serenji for the first time, we've made it easier to get set up by adding a walkthrough on the VS Code Welcome page. It takes you through: 

  • Setting up the server components.
  • Selecting a server namespace.
  • Saving and extending your workspace.
  • Requesting a debug license (don't forget we offer a free 30 day trial!) 

We've also added prompts and guidance throughout VS Code to open and add Serenji folders to your workspace and when going to run and debug code. 

This is just one of the ways we've enhanced the Serenji debugger to make straightforward and easy to use - so all you need to do is focus on your code.

Share volumes across pods and zones on EKS

Background

For a variety of reasons, users may wish to mount a persistent volume on two or more pods spanning multiple availability zones. One such use case is to make data stored outside of IRIS available to both mirror members in case of failover.

Unfortunately the built-in storage classes in most Kubernetes implementations (whether cloud or on-prem) do not provide this capability:

High Availability IAM

One of the recommendations when deploying InterSystems Technologies for production is to set up High Availability. The recommended API Manager for these InterSystems Technologies is the InterSystems API Manager (IAM). IAM (essentially Kong Gateway) has multiple deployment topologies.

Like many others probably find themselves, we were stuck doing live data mapping in our Interface Engine that we really didn't want to do, but had no good alternative choice. We want to only keep mappings for as long as possibly needed and then purge expired rows based upon a TTL value. We actually had 4 use cases for it ourselves before we built this. Use cases:

LDAP Authentication Question

I am trying to track down a problem we saw this morning with our TEST environment. We had a momentary issue where InterSystems HealthShare Health Connect could not connect correctly to LDAP. When we tried to login and could not connect to LDAP, the system would Delete our users.

the Test LDAP function would return a "Can't contact LDAP server". I went through the Certificates, made sure they had the correct permissions and were not expired.

I have an HL7 message that contains NTE segment with line break inside.

when I try to transform it (with DTL) it stops reading the message after the line break inside the NTE because it treat that as "End of Message".

Is there a way to solve this in the DTL or I need to run a pre process on the HL7 message that identify the line break inside the NTE segments and replace it with an escape char?

Receiving HL7 messages from our EMR, and processing to send out to downstream system. These are SIU_S12 messages, with a custom ZOR segment added by the EMR to include order information. The purpose of including this segment is to allow us to only send messages to the vendor that contain a procedure ID that is included on the list of procedures desired by the vendor. These values are in a LUT with the procedure ID in the key field, and a value of 1.

Hello Hello,

I am building a patient room door signage for a customer who has Trakcare already deployed. The app will reflect patient's data upon admission in the hospital (eg. name, male/female, doctor, mrn, special diet, etc...)

When the patient is discharged, "something" will tell the app that the patient was discharged and the screen will be reset.

Appreciate any kind of direction and help.

Thank you!

Reports roadmap

We are about to embark on a development where we'll be taking HL7 messages and generating PDF reports from them. We are wanting to future proof our development efforts within the constraints of our currently deployed platform and future upgrade options. We are currently running on Ensemble 2018, though an upgrade to Iris is anticipated - at some indeterminate point in the future. We are aware of Zen Reports and InterSystems Reports (Logi) as technology options, but are also unclear on some details. A roadmap and guidance from those who've done this kind of thing before would be great!

The idea for iris-user-manager

I want to deploy IRIS apps running in containers in Kubernetes with user accounts configured.

I have a %ZSTART routine which looks for an XML file with Users export data and if the %ZSTART routine finds this file, it imports it. This Users export data can be obtained by running a class method.

I have defined a task which can be scheduled or run on demand. This tasks imports user data from an XM file.

In Kubernetes I can provide a ConfigMap to stage the Users data for the %ZSTART routine.
