Introduction

In healthcare, information accessibility can impact the outcome of a medical decision, or the success of a bundled payment initiative. To ensure that the right information is available at the right place and time, healthcare organizations typically have used HL7® interface engines to share data among clinical applications. But the demands on healthcare information technology are changing so rapidly that these simple engines are no longer sufficient.

Migrating from Oracle, MSSQL, or other purely relational database systems to a multimodel InterSystems IRIS is a strategic decision that requires careful planning and execution. While this transition offers significant benefits, including enhanced performance, scalability, and support for modern architectures, it also comes with challenges. In this article I will highlight some of the considerations connected to coding to ensure a successful migration. I will leave everything connected to an actual migration of structures and data outside the scope of this article.


First, when you're considering migrating to a different database system, you need to understand your business logic, whether it's on the side of the application (application server) or the database server. Basically, where do you have your SQL statements that you will need to potentially rewrite?

Hi,

I tried to create what is know as a "class variable". As far as I understand the only analogy to class variables would be the "class parameters".

I tried to use a class parameter but I cannot change its value at runtime.

Parameter STATUSES = {{}};

Property repr As %String;

Method %OnNew(repr) As %Status
{
w ##class(Test...).#STATUSES
w ..#STATUSES

...

}

Hello,

I would like you to propose this challenge.

It has been created by the CodeWars community here: https://www.codewars.com/kata/6523a71df7666800170a1954/python

I will copy and paste the description:

🔡🟢 DESCRIPTION:

A number is Esthetic if, in any base from base2 up to base10, the absolute difference between every pair of its adjacent digits is constantly equal to 1.

Hi everyone.

I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.

To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.

Are table hints supported with embedded sql?

How to get server/instance info

Hi all,

As part of the development an API to know what is the instance of IRIS is connected, I've found some methods to know information about the server that can help you.

Get the server name: $SYSTEM.INetInfo.LocalHostName()

Get the server IP: $SYSTEM.INetInfo.HostNameToAddr($SYSTEM.INetInfo.LocalHostName())

Get the instance name: $PIECE($SYSTEM,":",2)

Message Count

Looking for a SQL query or any other method to find the Unique/distinct message counts for all productions or at least per production namespace within a given time frame. For e.g TimeCreated = January 2025 (Whole month)

I have used the following, but its not restricting the numbers based on the TimeCreated filter. Every time a new message is processed by system, its added to the total. I am running the query in today's date

Select Sum(MsgCount)

From

(Select DISTINCT TargetConfigName, count(DISTINCT SessionID) as MsgCount

FROM ENS.MessageHeader

Is anyone using Veeam as their external backup product?

I'm trying to backup a Linux VMs (VMWare; SUSE).

These VMs have a mirrored pair IRIS DB.

I'm using the InterSystems's provides pre-freeze - Backup.General(ExternalFreeze)
I'm using the InterSystems's provides post-thaw - Backup.General(ExternalThaw)

I've been running the backups with Veeam 'application aware processing' so I can add the pre-freeze and post-thaw scripts.

I'm backing up the PRIMARY node of the mirror pair.

Access to current line text

Is there a general way to set a variable XYZ equal to the text of the code line being executed now? Debugger or production. For example, for a code below if code is currently assigning a to 1, XYZ would be equal "S a=1". The same question about a variable containing current routine name.

S a=1
