Purpose:

We touched on some quick demos of  deep learning and machine learning over the past few months, including a simple Covid-19 X-Ray image classifier and a Covid-19  lab result classifier for possible ICU admissions. We also touched on an IntegratedML demo implementation of the ICU classifier.

It's well-known among Studio users that besides few predefined code fragments (for ObjectScript, Basic, MV Basic) it's possible to add user-defined code fragments. I found it rather convenient to use them as patterns that help to follow some conventions (internal standards) of writing, say, methods descriptions.

But I didn't find a way how to share these patterns, except dumb copy-pasting. Did somebody succeed with this task? Any help would be appreciated.

The use of Source Code Control systems in development is important. And there are a few systems known in the world, like GIT, SVN (Subversion), Perforce, Mercurial. Where the most popular nowadays is the git. Using it is very useful in many cases, but mostly it depends on the code as text, which can be compared between commits, branches, or versions of releases and so on. 

And InterSystems ObjectScript is not an exception, for many years it was possible to use SourceControl class in Studio, which helps to work with any Source Code Control System, and some companies already used it for many

i want to restrict certain IPs (ip for now and looking for more such parameters) from running my URL for security purposes...

i wanted to know how to access their ips and compare them with the list of restricted IPs, also if not IPs are there any other unique browser parameters which can be used for access control? and enhance security

A Webinar was held today for our Czech and Slovak partners and end users. This webinar was an online version of what we originally planned to present earlier this year in Fabrika hotel, Humpolec as a workshop. Due to the current epidemiologic situation a decision was made to move the workshop into the virtual space.

Error management on InterSystems languages has been evolving along time. Next, we will show the different implementations and why you should use the TRY/THROW/CATCH mechanism.

You can read official error recommendations here.

InterSystems will not mark as obsoletes the non-recommended error management methods to allow giving support to legacy applications. We recommend using tools like objectscriptQuality to detect that legacy unrecommended usage along with many other possible issues and bugs.

$ZERROR

$ZERROR is the older error management mechanism, supporting different implementations from

I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?

Just like the title, I want to do code version control. I don't want to change CLS at will, but I don't want to use MakeClassDeployed, I just want to set the cls or mac to read-only and uneditable state。Does CLASS have such property?

I need to consume the content of ^SPOOL output over SQL.
^%SPOOL utilities don't look so promising

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

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.

However, with the advent of API Management tools, some organizations are using it as a single point of authentication, preventing unauthorized requests to arrive at downstream services and decoupling

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.

Features demonstrated implementation include:

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.

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 defined various ways to load data into IRIS.

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.
If you want create new value canvas to this topic or any topic, download PPT version

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.

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.
