I am trying to compare times on an IRIS instance. The times are in the W3C format (https://www.w3.org/TR/NOTE-datetime). Are there any in-built helper functions in IRIS to support time comparisons in this format or will I need to parse it using functions such as $zdateh and $ztimeh to do the comparisons?

Hello,

Recently I tried to connect to JDBC on IRIS 2020.3+ and I came across the following error:

 SQL Error [461] [08S01]: [InterSystems IRIS JDBC] Communication link failure: Communication error: Server closed communication device

This error implies that the port is not open.

Checking with the netstat command:

irisowner@78c3e30b7f41:/opt/irisapp$ netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State

Purpose

Recently I noticed a Kaggle dataset  for the prediction of whether a Covid-19 patient will be admitted to ICU.  It is a spreadsheet of 1925 encounter records of 231 columns of vital signs and observations, with the last column of "ICU" being 1 for Yes or 0 for No. The task is to predict whether a patient will be admitted to ICU based on known data.

This dataset seems to be a good example of what's called "traditional ML" task. The data seem to have the right quantity and relatively right quality.

I use these example classes:
Class Sample.Address Extends (%SerialObject, %Populate)
{Property Street As %String;
Property City As %String;
Property State As %String(POPSPEC = "USState()");
Property Zip As %String;}
Class Sample.Person1 Extends (%Persistent, %Populate)
{  Property Name As %String;
Property Home As Sample.Address;
Property AR As array Of Sample.Address; }

In SQL it is Table Sample.Person1

No problem to define INDEX on Home_State

But Table Sample.Person1_AR

HowTo define an INDEX on AR_State ?
Index st On AR.State;

Does not compile!

Introduction

Nowadays, there is a lot of applications that are using Open Authorization framework (OAuth) to access resources from all kinds of services in a secure, reliable and efficient manner. InterSystems IRIS is already compatible with OAuth 2.0 framework, in fact, there is a great article in the community regarding OAuth 2.0 and InterSystems IRIS in the following link here.

Introduction

In a previous article, I discussed patterns for running unit tests via the  InterSystems Package Manager. This article goes a step further, using GitHub actions to drive test execution and reporting. The motivating use case is running CI for one of my Open Exchange projects, AppS.REST (see the introductory article for it here). You can see the full implementation from which the snippets in this article were taken on GitHub; it could easily serve as a template for running CI for other projects using the ObjectScript package manager.

I have a class:

Class test.Person Extends (%Persistent, %XML.Adaptor)
{
Property Name;
}

I want to serialize it into this XML:

<Person>
    <Id>1</Id>
    <Name>Ed</Name>
</Person>

Is it possible?

It's for the Visual Trace so I can't use %XML.Writer.

Does anyone have a Dockerfile for .Net/Java Gateways to share?

I'm trying out PEX and I think being able to run it as a docker container would be great.

To clarify I'm interested in container without IRIS, gateway only.

Hi Community,

Please welcome the new video from Global Summit 2019 on InterSystems Developers YouTube:

⏯ Scaling Up and Out on InterSystems IRIS

I try to compare classic JOIN against implicit JOIN.

It is a simple case. But I am surprised.

The class:
Class Sample.Person1 Extends (%Persistent, %Populate)
{  Property Name As %String;
Property Home As Sample.Address;
Property AR As array Of Sample.Address; }

Query #1 - classic:
select name,home_state,a.* from sample.person1 p
join sample.person1_AR a on p.Id=a.person1
and home_state=AR_state

Query #2 - implicit
select person1->name,person1->home_state,*
from sample.person1_AR where person1->home_state=AR_state

for both I have the same query plan:

It is a simple query on  2 or 1 simple  tables.

Keywords:  IRIS, IntegratedML, Machine Learning, Covid-19, Kaggle 

Continued from the previous Part I ... In part I, we walked through traditional ML approaches on this Covid-19 dataset on Kaggle. 

In this Part II, let's run the same data & task, in its simplest possible form, through IRIS integratedML which  is a nice & sleek SQL interface for backend AutoML options. It uses the same environment. 

IntegratedML Approach?

How to load data into IRIS

integredML-demo-template

Some clients ask me about migrate from Cache to IRIS. Why migrate to IRIS? Cache is excellent, stable, has good performance. These clients are right, but in the last years, the digital transformation imposed more complete solutions for the new requirements and InterSystems was a visionary to perceive it and launch IRIS.
It is a data platform ready to this digital transformation challenge. To show this, I created a Value Canvas.

Value canvas are a perfect tool to show in a few minutes the value of the change.

Hi,

Do you know if cache has programs and functions cache

I made a backup of my production base and when I use this function abouve I receve an error, but if I change any letter of the command the function go ok.

Didn´t work SELECT $$JOB1^KMIGxDESIG() FROM DUAL

Work sELECT $$JOB1^KMIGxDESIG() FROM DUAL

for this I.m using ODBC 64.

Thanks

Dynamic PoolSize (DPS) Experiment

Purpose:

Enhance Ensemble or IRIS production so it can dynamically allocate pool size for adapter-based components based on their utilization.

Sometimes, an unexpected traffic volume occurs, and default pool size allocated to production components may become a bottleneck. To avoid such situations, I created a demonstrator project some 2 years ago to see, whether it would be possible and feasible to modify production, so it allowed for dynamically modifying its components per their load.

Hi,

I have some SQL querys i would like to run using an Outbound SQL Adapter  and save the returned rowsets in excel format (each rowset in a seperate excel file).

What is the best way to do this?

Thanks

Hello,

I work on deploying IRIS inside Docker container. I really like %Installer class can automate many steps. I want to establish an ECP connection to a mirror database and then define a remote database on the application server. I have already seen we can create local database and namespace in %Installer. What code is needed to establish ECP connection?

Asymmetric cryptography is a cryptographic system that uses pairs of keys: public keys which may be disseminated widely, and private keys which are known only to the owner. The generation of such keys depends on cryptographic algorithms based on mathematical problems to produce one-way functions. Effective security only requires keeping the private key private; the public key can be openly distributed without compromising security.

In such a system, any person can encrypt a message using the receiver's public key, but that encrypted message can only be decrypted with the receiver's private key.

Robust authentication is also possible. A sender can combine a message with a private key to create a short digital signature on the message. Anyone with the sender's corresponding public key can combine the same message and the supposed digital signature associated with it to verify whether the signature was valid, i.e. made by the owner of the corresponding private key.

ML Toolkit for InterSystems IRIS, besides Python/R/Julia, allows orchestrating cloud-based advanced analytics services, such as Microsoft Azure Data Factory and Machine Learning:

This article, and following two articles of the series, is intended as a user guide for developers or system administrators, who need to work with OAuth 2.0 framework (further referred to as OAUTH for simplicity) in their InterSystems product based applications.

Those of you that worked already with ECP might know that it operates not only across
operating systems, processor technologies (big-little-endian), but also -with limits- across versions in C/E.
This cross-version feature also includes IRIS (verified for 2020.1)  and C/E (2018.3)

Hello All,

I have been using IRIS / Ensemble for over a decade and appreciate lot of it's functionalities and features, however besides having a UI of 80's era (which doesn't bother me), what I believe where IRIS is lacking is lack of out of the box connectors (services/operations).
If we look at IRIS's competitors for eg Mulesoft, Talend, Boomi they all have hundreds of pre-built connectors for major applications like Salesforce, SAP etc and cloud services like Azure, AWS etc to store and retrieve information and data.

Just to give an idea here is a link of Dell Boomi connectors

Hi Developers,

The new video from Global Summit 2019 is available on InterSystems Developers YouTube:

⏯ REST at Ease

Messages between Business Hosts in Interoperability Production often contain object properties.

Do you define and pass them as object properties or do you define and pass them as Integers with objects conversion where required?

Why?

InterSystems IRIS database supports compression? If yes, wha is possible compress? (logs, temp tables, blob data, backup, etc)
