AWS launched their first generation of Amazon EC2 A1 instances last year, powered by Arm-based AWS Graviton processors. At AWS re:Invent 2019, Amazon announced the second-generation AWS Graviton2 processors and associated Amazon EC2 M6g instance type, boasting up to 40% better price performance over current generation Intel Xeon based M5 instances.

The AWS Graviton2-based M6g instances are currently in preview, and InterSystems jumped on the opportunity to measure their performance with the InterSystems IRIS Data Platform.

Managed File Transfer (MFT) feature of InterSystems IRIS enables easy inclusion of a third-party file transfer service directly into an InterSystems IRIS production. Currently, DropBox, Box, and Kiteworks cloud disks are available.

In this article, I'd like to describe how to add more cloud storage platforms.

Here's what we're going to talk about:

• What is MFT
• Reference: Dropbox
  • Connection
  • Interoperability
  • Direct access
• Interfaces you need to implement
  • Connection
  • Logic
• Installation

Hello

I am creating an import tool to convert a client's JSON data into IRIS classes.   The sample file is over half a gig.   I am copying the data into an instance of  %Stream.FileCharacter;.    My first few attempts worked fine.   However I started getting an error thrown when I try to create a DynamicAbstractObject using the  %FromJSON method.     See the code below.   The error code given is not in the documentation, at least not the doc that I was searching.   

       "READ error while reading input stream, Line 5121169 Offset 23, error code 10"

Can anyone shed light on this error code?

Hi Community,

System Alerting and Monitoring (SAM) in InterSystems IRIS data platform helps you efficiently monitor and manage your systems. This video shows some solutions it offers for specific challenges faced by developers and operators:

March 23, 2021 – Alert: Potential Data Integrity Issue with Mirror Dejournaling

InterSystems has corrected a defect that can cause data inconsistency issues on non-primary mirror members in extremely rare circumstances. This defect affects all released versions of InterSystems products.

If the defect occurs, it happens silently during normal operation on a mirrored system. The result of this defect is that a mirror member fails to dejournal a subset of journal records, which then leads to data inconsistency across mirror members. This affects both failover and async members.

Hi All,
I am implementing REST API's in IRIS using the below link as a guide. 
I chose this approach so i could have a single entry point for requests regardless of namespace

https://community.intersystems.com/post/restful-exception-handling 

a sample form the HIHLib.REST.Server class i am using is below. my question is does IRIS and CSP cache responses for requests to the CSP.REST class?
and if so what parameters or properties do i need to enable?

i notice the %CSP.Page class that %CSP.REST inherits from has an EXPIRES parameter that can be set, and %CSP.

Routing acks from one operation to another:

I was working on a scenario in which I wanted the acks and/nacks received from one downstream system to another interface which is not the source of the original message. Is there a way to achieve this scenario?

The reason being there's a separate interface handling the acks and will be used to manage the errors.

Thank you for the help!

Introduction

InterSystems has recently completed a performance and scalability benchmark of IRIS for Health 2020.1, focusing on HL7 version 2 interoperability. This article describes the observed throughput for various workloads, and also provides general configuration and sizing guidelines for systems where IRIS for Health is used as an interoperability engine for HL7v2 messaging.

Is there an easy way to see if a class object has been compiled or needs to be?  Or to get a list of classes that need to be compile in a particular namespace?

Hi,

Im wondering if its possible to pass a SQL query through to the Power BI IRIS Connector? I can't currently see an option - and have tried through advance editor to use M Query syntax to attempt this with no luck. 

Has anyone else in the community had any luck or know if this is supported?

Thanks.

IRIS use MIRROR to ensure the continuous operation of the hospital business, but MIRROR synchronization data does not contain (web application configuration information, task plans, sql gateway, etc.), about the synchronization of such information do we have a better solution to solve this problem?

It is common to test a connection sending a general SQL instruction to the database, in Oracle we send select 1 from dual, for example, and in IRIS what the best option?

Hey everyone.

I have a process where I create a new %Stream.FileCharacter object, specify the filename (including it's path), write data to the stream, and then save. However for some reason, if the user account does not have write access to the directory, the %Save method is still returning true even though it was unable to actually write the file to the folder.

The location is a UNC path, and I'm wondering if this is tripping me up?

Hi 

I have a class in several namespaces. This class is what I call a common component in that it is a class that performs a certain set of functions that are common to a number of Interfaces. In this example the class is essentially a Message Queue. When a Data Event is created in my source database I want to invoke the CreateMessage() class method in all of Interface namespaces.

The common component class has a name DFI.Common.Queue.ODSMessageQueue. I can inherit the class into one or more classes e.g. DFI.Common.Queue.Interface1MessageQueue, DFI.Common.Queue.Interface2MessageQueue.

In my previous article, we reviewed possible use-cases for macros, so let’s now proceed to a more comprehensive example of macros usability. In this article we will design and build a logging system.

Logging system

Logging system is a useful tool for monitoring the work of an application that saves a lot of time during debugging and monitoring. Our system would consist of two parts:

• Storage class (for log records)
• Set of macros that automatically add a new record to the log

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Hi, folks!

Sometimes I need to schedule a task programmatically.

And in 99% I need having some class method be periodically called.

And I want to have the schedule be started by one line. As a job in crontab.

I decided to introduce such a module with iris-cron-task module.

See the details below!

During some consulting activity, I found at the client's site CACHEAUDIT database of more than 100 GB size. The reason was simple: several processes produced a great amount of %System/%System/OSCommand audit records due to frequent external calls ($zf(-100,.)). As it is well-known, those events can be easily disabled systemwide, while this can be hardly considered secure enough. Reducing the number of days before audit cleanup from default 62 to some reasonable figure (e.g.

Most CloudFormation articles are Linux-based (no wonder), but there seems to be a demand for automation for Windows as well. Based on this original article by Anton, I implemented an example of deploying a mirror cluster to Windows servers using CloudFormation.I also added a simple walk through.
The complete source code can be found here.

Update: 2021 March 1 I added a way to connect to Windows shell by public key authentication via a bastion host as a one-liner.

We have multiple NTE segments in the ADT message.  I need to loop through all of the NTE segments looking for "NAVIRADTHPT" in the NTE-4 field.  I have yet to get this to work using the following code.  

HL7.(NTE:4()) Contains "<NAVIRADTHPT>"

Here's how the segments look.

NTE|1||This patient is currently being seen for radiation therapy.|AHRADTHPT||20210223093342
NTE|2||This patient is currently being seen for radiation therapy.|NAVIRADTHPT||20210223113634

I've also tried it this way with no luck.

HL7.(NTE():4) Contains "<NAVIRADTHPT>"

Any help would be greatly appreciated!

Can a license be reserved for a specific user or group of users? So if I have 20 available licenses, only allow other users to use 19 of them while keeping one open for this specific user?
