Hey everyone.

As part of an ongoing mission to track down orphaned HL7 Messages in our integration engine, I have been digging into our environment to track down the causes.

Having looked at various posts here (including one of my own) there are a few scenarios that can create orphaned messages resulting in excessive disk space usage. These scenarios are generally:

Hello Community,

I am facing a JDBC connection issue after migrating from Caché 2016 to Caché 2018.1. When I attempt to connect using the following connection settings:

CACHE_DATASOURCE_URL=jdbc:Cache://localhost:1972/TEST

CACHE_DB_USERNAME=test

CACHE_DB_PASSWORD=test

I consistently receive the following error:

[Cache JDBC] Communication link failure: Access Denied

This configuration worked perfectly with Caché 2016. I have verified the following:

We have created a CSP application in the path /csp/ourapp. Due to some session handling issues, we created a new web application /csp/ourapp/hl7mapping that points to the sane namespace, and we now access the CSP pages using this new URL. This works fine in the local system.

After deploying the app to server, we are facing issues around compiling CSP pages.

Hey Community,

Last week, the InterSystems team held our monthly Developer Meetup in a new venue for the first time ever! In the AWS Boston office location in the Seaport, over 71 attendees showed up to chat, network, and listen to talks from two amazing speakers. The event was a huge success; we had a packed house, tons of engagement and questions, and attendees lining up to chat with our speakers afterwards!

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class.

After we rolled out a new cointainer based on containers.intersystems.com/intersystems/irishealth:2023.1 this week, we suddenly noticed that our FHIR Repository started responding with an Error 500. This turns out to be caused by PROTECT violations on the new HSSYSLOCALTEMP namespace and database used by this version of the IRIS for Health FHIR components.

Does %OSCertificateStore only check the trusted root folder in windows?

Can it be used for Personal store on servers or is there another condition can be used?

Used it for a first time and writing a function to check specific ones being used for expiry but had one this week that was to be installed in personal rather than the trusted root and didn't know if stating OSCertificateStore or a url otherwise to look in the personal installed certs on the server could be used instead so stuck with the original way (which can get confusing)

There's a pattern I've encountered several times where I need to use a temp file/folder and have it cleaned up at some point later.

The natural thing to do here is to follow the patterns from "Robust Error Handling and Cleanup in ObjectScript" with a try/catch/pseudo-finally or a registered object to manage cleanup in the destructor. %Stream.File* also has a "RemoveOnClose" property that you can set - but use with care, as you could accidentally remove an important file, and this flag gets reset by calls to %Save() so you'll need to set it back to 1 after doing that.

There's one tricky case, though - suppose you need the temp file to survive in an enclosing stack level. e.g.:
