#InterSystems IRIS

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 Marx for 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:">")

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:

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

I know that 1-1 relationships are not officialy supported by intersystems cache/iris so I want to know the best way to store data with this kind of data model.

Currently I have two classes that where implemented some time ago:

Table A with a relationship type one on table B

Table B with a relationship type one on table A

To compile I have a double compile with qualifyer U.

What is the best way to implement a data model with 1-1 relationships?

Thank you

Hi,

We are using IRIS, and have some systems that we send data to that cannot accept messages with certain fields larger than a particular size.

Is there any way to utilize the schema to truncate any fields that are larger than the entered data?

I've tried just setting the max lengths and doing the transform, but it puts in the entire string, and can't find a topic for it.

There are a large number of fields that need to be truncated, so it would be ideal to get it to respect the hl7 schema maximum lengths.

ie for the XPN name fields, each name may not be larger than 20 characters.

Hey Developers,

Hi, how do I add the POST body content to my Net.HttpRequest (It's not a key value pair, I am posting my own JSON to the remote server because it needs JSON in the body):

                set httpRequest=##class(%Net.HttpRequest).%New()

Hi, folks!

Do you know the option/mode when I can feed multiline code into a terminal?

E.g. 

for i=1:1:100 {

/// do one line

///do something else}
