Accessing Azure Blob Storage

Accessing an Azure cloud storage to upload/download blobs is quite easy using the designated %Net.Cloud.Storage.Client class API methods, or using the EnsLib.CloudStorage.* inbound/outbound adaptors.

Note that you'll need to have the %JavaServer External Language Server up and running to use the cloud storage API or adaptors, since they both use the PEX framework using the Java Server.

Here is a quick summary:

It's been a long time since I didn't write an update post on IoP.

So what's new since IoP command line interface was released?

Two new big features were added to IoP:
- Rebranding: the grongier.pex module was renamed to iop to reflect the new name of the project.
- Async support: IoP now supports async functions and coroutines.

Git link: https://github.com/ecelg/InterSystems-IRIS-as-a-Spotify-REST-client

Recently, I come up an idea in my mind that how can I put my playlist on IRIS.🧐

At the same time, I was told to pay for my Spotify subscription💸💸... ooo.. how about to get some data from the Spotify API... so I started to do study about it.

I have a question about using OnInit() within a Ens.BusinessOperation.

When you include OnInit(), does OnInit() only execute when you start a Business Operation? Or does it execute OnInit () every time you send a REST request to the operation. I am trying to pinpoint when the best time is to execute the POST command to get the Token

I am needing to get a Bearer Token from a REST POST call and return the Authorization key prior to making the rest of the REST calls to pull down data.

One of the challenges of creating a DICOM message is how to implement putting data in the correct place. Part of it is by inserting the data in the specific DICOM tags, while the other is to insert binary data such as a picture - In this article I will explain both.

To create a DICOM message, you can either use the EnsLib.DICOM.File class (to create a DICOM file) or the EnsLib.DICOM.Document class (to create a message that can be sent to PACS directly). In either case, the SetValueAt method will allow you to add your data to the DICOM tags.

In your Interoperability Production you could always have a Business Operation that is an HTTP client, that uses OAuth 2.0 for authentication, but you had to customize the Operation for this authentication methodology. Since v2024.3, which was lately released, there is a new capability, providing new settings, to handle this more easily.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

I have an operation using $ZF this operation ran and did not error but the job has been active and it can not be stopped I have tried stopping it from the front end and through the terminal using ##class(ENSLIB.Job).%New() Stop method. Now my production will not update even if I add a new item to the production I cannot update the item is there a way to force stop this job.

As I begin our adventure into using an External FHIR Repository, I wanted to see what opinions people have about a design Idea I was working on.

I want to create a way that my Team has the ability to send a Message Type, and the system knows from that Message Type which FHIR queries to execute and return the Response back to the user, sort of like a FHIR Query Hub. Does this sound reasonable?

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation. Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation?

Trying to start investigating an error we are seeing with multiple of the same messages getting sent to the same vendor. We receive an HL7 message with an RTF embedded from our EMR, send it through a DTL to just update the Patient Class, and then send it onto the Operation which is TCP.

We are starting to see this error message...

Hi,

We're having an issue with some messages being sent to a downstream system from Healthshare. Part of the free text in the NTE segment is displaying with special characters on the system front-end but is not present in the HL7 message that we send to them. We are guessing that this is a result of some of the text being copied and pasted from something like MS Word. The '?' on their system is just representing an invalid character.

Is anyone aware of a way to prevent this occurring? We are sending the messages using the 'cp1252' encoding.

WSDL for a CDC vendor was provided with a URL using a custom socket (non 443). Everything generated fine, but when making calls to their https:// URL that has their custom port in the URL - no response comes back. The assumption is, their server isn't even processing the request, as Postman does using the custom https://path.to.server:NNNN port in the URL.
