#InterSystems IRIS

Hi Developers,

Please welcome the new video, specially recorded by @José Pereira for the InterSystems IRIS AI Programming Contest: 

⏯ Monitoring your ML model with IntegratedML

GA releases are now published for the 2020.2 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

A full set of containers for these products are available from the WRC Software Distribution site, including community editions of InterSystems IRIS and IRIS for Health.

The build number for these releases is 2020.2.0.211.0.

InterSystems IRIS Data Platform 2020.2  provides an important security update with the following enhancements:

• Support for TLS 1.3
• Support for SHA-3

InterSystems IRIS for Health 2020.2 includes all of the enhancements of InterSystems IRIS.

This is the second post of a series explaining how to create an end-to-end Machine Learning system.

Exploring Data

The InterSystems IRIS already has what we need to explore the data: an SQL Engine! For people who used to explore data in csv or text files this could help to accelerate this step. Basically we explore all the data to understand the intersection (joins) which should help to create a dataset prepared to be used by a machine learning algorithm.

I send ORUs to a process where a transform is applied before sending the message to a process where the routing is handled. A recent request was made that when OBR:25="D" the message is also be faxed with transforms that have some similarities to the original, but not exactly the same. I copied the DTC, made the alterations, and created a separate rule to handle it. However, when I run a message through with a "D" in OBR:25, it is only sent to the routing process once.

Hi Community,

Please welcome the new video, specially recorded by @Renato.Banzaifor the InterSystems IRIS AI Programming Contest: 

⏯ IRIS ML Suite Demo

Following up the previous part, it's time to take advantages for IntegratedML VALIDATION MODEL statement, to provide information in order to monitor your ML models. You can watch it in action here

The code presented here was derived from examples provided by either InterSystems IntegragedML Template or IRIS documentation, my contribution was mainly mashing up such codes. It's a simple example intended to be a start for discussions and future works.

Note: The code presented here is for explanation purpose only.

A few months ago, I read this interesting article from MIT Technology Review, explaing how COVID-19 pandemic are issuing challenges to IT teams worldwide regarding their machine learning (ML) systems.

Such article inspire me to think about how to deal with performance issues after a ML model was deployed.

I simulated a simple performance issue scenario in an Open Exchange technology example application - iris-integratedml-monitor-example, which is competing in the InterSystems IRIS AI Contest. Please, after read this article, you can check it out and, if you like it, vote for me

Hello, guys!

I'm facing a problem when I compile my code in Atelier (version 1.3) when connected to an Iris Community instance in Docker container. 

When compiling, the code is synchronized with the server correctly, however, in the IDE, the code is inserted into the class again.

Class after compile:

InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time.

We understand, however, that for testing and other specific purposes, you may want to run InterSystems IRIS-based containers from InterSystems under Docker for Windows.

Hey Developers,

New "Coding Talk" video was specially recorded by @Yuri.Gomesfor the InterSystems IRIS AI Programming Contest: 

⏯ SAPPHIRE - AutoML UI to InterSystems IntegratedML

As you probably know, InterSystems IRIS has a mechanism for auto-generating methods. So, when you create an index in a class, you create methods that make your work easier. There is also a good article on Community that describes such methods.

Take, for example, IndexNameOpen(val), where IndexName is the name of the corresponding index. This method returns an object in which the value of this index corresponds to the value of val.

But this method is available only for unique indexes.

I want to map global ^myUnitTests(ID)={Start}_"^"_{JOB} where {Start} and {JOB} are two properties and ID is determined by $Increment(^myUnitTests).

I defined this class but it will not compile:

Class UnitTest.

Hi,

Business Rules can define a context object,  whose properties are exposed and used in the expressions of the rules. For example, my context object is an object with 3 properties. PropA, PropB and PropC.

When constructing my rules, I can call a custom function, and I have one I built myself called 'myFunction' which takes arguments and I pass in properties of my context object. (I can pass in the value of the context object's PropA, B or C).

Hello,

I am using a class based on %UnitTest.TestProduction to test Health Connect production.

I read in Class Reference IRIS for UNIX 2020.1:

Note: This class is not intended to be used in InterSystems IRIS instances.

Why should this not be used in IRIS? I have not seen any difference using this with HealthConnect 2017 or IRIS 2020.1

Pyodbc supports calling stored procedure  , but if the IRIS Stored Procedure ROWSPEC has a column with datatype specified as %Date or %Time, Pyodbc fails to fetch it and throws this error.

"

pyodbc.Error: (' 2201', '[ 2201] [Cache ODBC][State :  22018 ][Native Code 22005]\r\nERROR #388: Unknown error, code 22005 (22005) (SQLGetData)')

"

on printing the cursor execute description, pyodbc reads the column as <int>.

and if the ROWSPEC datatype specification was removed, it fetches successfully.

i'm using the driver "InterSystems IRIS ODBC35"  2019.2.0.107

Hello Community members, am newbie here
Already learning and working through Studio & Terminal and since am from C# background and trying to use VS Code for ObjectScript coding, appreciate you help, unable to edit files, please see below snapshot

Hi All,

With this article, I would like to show you how easily and dynamically System Alerting and Monitoring (or SAM for short) can be configured. The use case could be that of a fast and agile CI/CD provisioning pipeline where you want to run your unit-tests but also stress-tests and you would want to quickly be able to see if those tests are successful or how they are stressing the systems and your application (the InterSystems IRIS backend SAM API is extendable for your APM implementation). 

Hi guys,

I released the Sapphire - Auto ML UI to IntegratedML in first version. This week we will release more features. At moment you can create your models.

New features to the next 3 days: model training, csv import, model validate and model performance report.

Enjoy!

I try to run a small test routine (guessing a random number) in WebTerminal but the result looks broken.
in IRISterminal:

 in WebTerminal:

I think it relates to backspace.
Is there some special setting required?

The code:

a
 s q=".......... guess [0..9]: " 
 f i=1:1 d b if p w ! w $c(9),"thank you",! q
 q  
b
 w !,i,$c(9),q
 f  r v#1 q:(v?.1n) w " !no number",$c(8,8,8,8,8,8,8,8,8,8,8,8)
 w " "
 s r=$R(10),p=$s(v="":1,v=r:"!",v>r:"<",1:">")
 s x=q,$e(x,r+1)="*",$e(x,v+1)=$s(v=r:"!",v>r:"<",1:">")

Hey Community,

We're pleased to invite all the developers to the upcoming InterSystems IRIS 2020.1 Tech Talk: Speed Under Pressure on July 14 at 10:00 AM EDT!

In this InterSystems IRIS 2020.1 Tech Talk, we'll learn about the open source Ingestion Speed Test. We will explain:

• the architecture of the ingestion speed test
• how we are leveraging Docker containers to run it on our PCs
• how we are leveraging InterSystems Cloud Manager to easily run it on AWS so we can compare InterSystems IRIS with other databases, such as AWS Aurora 

After this Tech Talk, you'll be able to use the Ingestion Speed Test on InterSystems Open Exchange for your own testing and benchmarking.

Hey Developers! 

Join our next competition in creating open-source solutions using InterSystems IRIS Data Platform! Please welcome:

➡️ InterSystems IRIS AI Programming Contest ⬅️

Duration: June 29 – July 19, 2020. 

What is the best option to consume rss data and store in the DocDB?

Imagine you want to see what InterSystems can give you in terms of data analytics. You studied the theory and now you want some practice. Fortunately, InterSystems provides a project that contains some good examples: Samples BI. Start with the README file, skipping anything associated with Docker, and go straight to the step-by-step installation. Launch a virtual instance, install IRIS there, follow the instructions for installing Samples BI, and then impress the boss with beautiful charts and tables. So far so good. 

Inevitably, though, you’ll need to make changes.

I got a resultset, and some columns might be a JSON_OBJECT. Is there a way (based on metadata) to determine that the column was formed from JSON_OBJECT function?

set rs = ##class(%SQL.Statement).%ExecDirect(,"SELECT 1 colA, JSON_OBJECT('id':1) col2")
do rs.%Display()

I do not want to try parsing json.

Currently , I am using objectscript in Iris. If I switch the code from objectscript to Java means what are all the steps I need to do?

Hi,

Could someone help me in identifying all characters in a column is whole number 0 or greater

CASE WHEN '123' %MATCHES '[0-9]*' then 'VALID' else 'INVALID' end

The above statement is finding only for first character.

Thanks

Hello.
We're trying to create a script that compiles everything on a certain namespace, for that we are depending on CompileAll. However it seems that this method doesn't check for a dependency tree even when using flags like: curb.

Due to its apparent alphabetical nature, classes that come first but depend upon classes that come later fail to compile because their object still doesn't exists. Example:
Suppose we have to compile a class in which its name starts with A and it has a Parameter which contains an expression that calls for B.

I was trying the %JSON.Adapter backport to cache and try it also in IRIS and i found a kind of an issue regarding to export and object to json that is an inheritance of %ListOfObjects
If we have a list of elementtype of and object and then we try to export this to a json we get this json instead of a correct json.

exported json:

{
  "ElementType":"test.element",
  "Size":"1"
}

Json that we want:

[
  {
    "field1":"testField1",
    "field2":"testField2"
  }
]

Test classes:

Class test.elementList Extends (%ListOfObjects, %ZJSON.Adaptor)
{ 
 /// The type (class name) of the elements stored in the collection.

Hey Developers,

We're pleased to invite you to the upcoming "Development of Interoperability Business Hosts with PEX in Java/.Net" webinar by InterSystems Russia on July 16 at 10:00 (UTC+3, Moscow time)!

I would like to know if there is a way of having a callback or something similar, on persistent classes that is always called after the execution of the operation (failed or successfull).

%OnOpen is executed prior to the action, and there is no post callback

%OnAfterDelete and %OnAfterSave are executed after a successfull operation
