Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

Polybase and IRIS

Hi all, I am trying to use Polybase in SQL Server 2019 to access an external Cache/IRIS Database. I have followed the initial steps of enabling Polybase, creating a Database, DB scoped credential and then an External Data Source. These steps have not caused any issues and appear to be successful, I am using the same DSN we use for a Linked Server connection that works normally. I am running into an Error when trying to Create an External Table. The error is a generic Native Code 469 "Driver Not Capable".

Method or Class Method?

For programmers new to ObjectScript, one question will inevitably arise: “What is the difference between methods and class methods?” A typical answer would be: “A class method applies to a class, but a method applies to an instance of that class.” While that answer is correct, it lacks important information on how these methods di

LS,

I'm executing a query using JDBC on a PostgreSQL db:

SET statement_timeout TO 600000000; COMMIT SELECT * FROM bi_hour

The query is aborted with the following message:

FOUT #5023: Fout in Java Gateway: JDBC Gateway getClob(0,2) errorBad value for type long : active

The column 'blocked_status' contains the value 'active' is of type 'text'. I figure somewhere the SQL Gateway tries to convert the text value into a long but I can't find where, any suggestions?

Hey Developers,

Watch this video to discover an analytical approach to InterSystems IRIS encryption and how it interacts with storage compression and deduplication compared with storage-level encryption:

I'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:

I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.

Overview

After having some discussions at Global Summit and using a lot of package managers in my day to day development (npm,nuget,Chocolatey, etc) in addition to recently using the InterSystems Package Manager for some CICD process I'm building using Intersystems IRIS and IRIS 4 Health, I wanted an easy and integrated way to search/view/install packages related to the Intersystems tech stack.

When registering the components: I used this command:
"Utils.migrate("/external/src/CoreModel/Python/settings.py)" ;
The error appears: "An error has occurred: iris.cls: error finding class",
I changed with these two lines:
result = subprocess.run(["iop", "-m", "/external/src/CoreModel/Python/settings.py"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, check=True)
subprocess.run(["iop", "-m", "/external/src/CoreModel/Python/settings.py"], stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL, check=True)

Hey,

I'm testing a REST API that is used for our IRIS Backend with a mobile app (Angular / ionic).

The problem is that, our test environment does not yet have HTTPS capabilities, it's something we're going to set up ASAP, but right now we don't have it set up.

We want to test the API endpoints via a web browser using either a test application built in Angular, or the app itself built with NPM via the browser. This means that the set-cookie headers are being blocked by the browser.

Hello community,

I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!
