Hi guys!

As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).

1. Get it by as a property of an instance with "Object access":

ClassMethod GetPropertyForID(stId As %Integer) As %String

{

set obj=..%OpenId(stId)

return obj.StringData

}

2. Get it as a value of a column of the record with "SQL access":

For each defined property, query or an index, several corresponding methods would be automatically generated on a class compilation. These methods can be very useful. In this article, I would describe some of them.

Hi All,

I'm just taking a look at IRIS and what it has to offer, and if this is something the organisation I work for should be looking to take advantage of.

I think I've come across an early sticking point, and I wondered if anyone knew of any options.

Presenter: Dan Kutac
Task: Use a common login identity and a central mechanism of authentication across environments from multiple entities
Approach: Provide examples and code samples of an application environment using OpenID Connect and OAuth 2.0
 

Description: In this session we will demonstrate an application environment using OpenID Connect and OAuth 2.0. Hear how this is done and what options you have; and yes, you get to keep the code.

Problem: How to use a a common login identity (e.g. Facebook credentials) and a central mechanism of authorization cross environments from multiple entities.

Solution: Create awareness and interest in using OAuth 2.0

InterSystems IRIS Roadmap

Hello all,

We recently moved our workstations to Windows 10 and so we updated all our local installations to IRIS (servers already run IRIS 2019.1). Now we are trying to connect our pyCharm to IRIS but we can't succeed.

It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

The 2019.2 version of InterSystems IRIS Studio is now Generally Available!

InterSystems IRIS Studio 2019.2 is the first release of our cross-product Studio development tool.  It can connect to InterSystems IRIS servers and also to Caché/Ensemble servers, and behaves appropriately for each.  This helps developers that want to work across both sets of products as well as those that want do develop against containerized IRIS using Studio.

How can I remove elements from $lb property? Specifically last element?
$list does not work with $lb properties.
$listupdate can't remove elements
The only solution I found is a temp variable and $list, but isn't there something better?

This series of articles would cover Python Gateway for InterSystems Data Platforms. Leverage modern AI/ML tools and execute Python code and more from InterSystems IRIS. This project brings you the power of Python right into your InterSystems IRIS environment:

• Execute arbitrary Python code
• Seamlessly transfer data from InterSystems IRIS into Python
• Build intelligent Interoperability business processes with Python Interoperability Adapter
• Save, examine, modify and restore Python context from InterSystems IRIS

The plan for the series so far (subject to change).

New session recording from Global Summit 2018 is available on InterSystems Developers YouTube Channel:

InterSystems IRIS Reference Architectures

InterSystems has corrected a memory leak in applications that pass by reference to a formal parameter that accepts a variable number of arguments.

This problem exists for:

• InterSystems IRIS Data Platform – all currently released versions
• InterSystems IRIS for Health – all currently released versions
• HealthShare Health Connect 2019.1.0

If this defect occurs, the process partition will eventually be exhausted, resulting in a <STORE> error.

Hi! I am working in a java project (Spring Boot+ Maven + Hibernate) using jpa/hibernate to manage the persistance with the IRIS database from the Docker image (store/intersystems/iris:2019.2.0.107.0-community) and I've found an issue using the IRIS instance, when I define tables with relationships OneToMany, ManyToOne or ManyToMany and I try to fetch all the rows of the tables using the default method findAll (JpaRepository implements that method to get all the rows by default) the query automatically exceeds the limit of licenses availables. I've tested the same query using a local IRIS

InterSystems IRIS - Power of the Platform

1.About this article

Just like Caché pattern matching, Regular Expressions can be used in Caché to identify patterns in text data – only with a much higher expressive power. This article provides a brief introduction into Regular Expressions and what you can do with it in Caché. The information provided herein is based on various sources, most notably the book “Mastering Regular Expressions” by Jeffrey Friedl and of course the Caché online documentation. The article is not intended to discuss all the possibilities and details of regular expressions. Please refer to the information sources listed in chapter 5 if you would like to learn more. If you prefer to read off-line you can also download the PDF version of this article.

Hi,

I try to implement an iFind index.

Here is my definition class :

The problem start when I add an Relationship in my indexed class, I end up with this error :

Have enabled LDAP for our numerous , Ensemble, IRIS and cache instances with many namespaces. All is working fine and the ldap logins work.

But have noticed that the first instance that the user logs into the namespace is assigned to that user, but when that user than logs into another instance the default namespace from the first login is still there and doesn't update to the new namespace.

So this doesn't effect the ldap login but is now effecting the terminal logins where the user is now getting access denied.

Not sure why the first namespace is not being replaced by the current namespace.

Now that the InterSystems IRIS Data Platform Community Edition is available on Docker Hub (https://hub.docker.com/_/intersystems-iris-data-platform), it seems like a great time to try InterSystems IRIS in a container. For some time already, the community edition has been available in the cloud, for example on AWS (https://community.intersystems.com/post/free-iris-community-edition-aws), but maybe it would be nice to try it locally as well. Fellow Windows users are no doubt used to eye rolling, being told “YMMV”, etc., whenever they mention using Docker for Windows. Sometimes we are even told

The 2019.2 version of InterSystems IRIS Data Platform is now Generally Available!

Container images for InterSystems IRIS are available via the WRC's download site.

The build number for these releases is 2019.2.0.107.0.

 InterSystems IRIS Data Platform 2019.2  is the first CD (continuous delivery) release of InterSystems IRIS.  It has many new capabilities including:

I'm a beginner with Health connect.  Trying to create a bi-directional interface.  is there a specific class I should use on the business  operations/services?

InterSystems IRIS in a Container

Hi Community!

I have very good news for the developers, who are using GitHub to host projects with InterSystems ObjectScript.  GitHub introduced the support of InterSystems ObjectScript this week!

How does it work?

Now all the .cls files in your repository are considered as InterSystems ObjectScript and highlighted according to the language rules of ObjectScript. For example WebTerminal, Samples-Data.

During testing your code you are often confronted with the need to examine
the actual content of an object. Either using ZWRITE or $system.OBJ.Dump()
you get a picture of simple properties as "--- attribute values ---"
while "--- swizzled references ---" are more confusing than informative
and with "--- calculated references ---" you are just left in the lurch.

This small helper class allows you to dump an object to terminal or
e.g in background to some stream for later review.
By default, you see just properties with content,

   DO ##class(Z.obj).dumpToDevice(obj)

Adopting InterSystems IRIS

InterSystems has corrected a defect that can result in application data integrity issues following an abnormal shutdown.

This problem exists for:

• Caché and Ensemble 2018.1.2
• HealthShare Health Connect (HSAP) 15.032 on Core version 2018.1.2
• InterSystems IRIS Data Platform 2019.1
• InterSystems IRIS for Health 2019.1
• HealthShare Health Connect 2019.1

The defect breaks the journal sync guarantee that all updates in the journal buffer have been written to the journal file. The failure is silent: it does not generate an error message and there is no entry about it in any log file.

Has anyone done any integration with Kafka, especially prior to IRIS? If yes what was your experience such as specific pain points to be overcome.

David

Greetings,

Is there any default exception handling feature available in Zen report? I am working on a report that comprises of several different composites report (%ZEN.Report.Display.composite). I am incorporating several composites into the main Zen report, If any composite fails or encounters an issue such as issue with the sql statement or class method which i am using to fetch the data, the report (pdf) fails and shows a Zen error. It is very hard to find an exact composite or code that causes the error as Zen report displaying a generic Zen Error without any details.

Hi All,

I have a REST dispatcher class in which I enabled the Parameter HandleCorsRequest = 1;

I can able to access the API using Postman, but not with my web application. It throws the below error.

Access to XMLHttpRequest at 'https://ec2-10-200-XXX-X.com/REST/MRM/get/Message?MessageCode=ERR0006&L…' from origin 'https://ec2-80-106-XX-XXX..com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
