#InterSystems IRIS

The following steps show you how to display a sample list of metrics available from the /api/monitor service.

In the last post, I gave an overview of the service that exposes IRIS metrics in Prometheus format. The post shows how to set up and run IRIS preview release 2019.4 in a container and then list the metrics.

This post assumes you have Docker installed. If not, go and do that now for your platform :)

Step 1. Download and run the IRIS preview in docker

Follow the download instructions at Preview Distributions to download the Preview Licence Key and an IRIS Docker image.

In our latest episode of Data Points, I had a conversation with @Thomas Dyar about AI Link, which helps bridge the gap between data scientists and business analysts. Our conversation talks about how AI Link fits with IntegratedML and Adaptive Analytics, as well, as what new features are on the horizon for IntegratedML. Take a listen!

Hi,

I tried to join my local DB table with link table. but I am getting below error.

5475 5475 reporterr2+40^%occRoutine Error #5475: Error compiling routine: %sqlcq.HSANALYTICS.cls483.  Errors:  %sqlcq.HSANALYTICS.cls483.cls(%OnNew+5) : SQLCODE=-161 : References to an SQL connection must constitute a whole subquery

I tried to execute below query in Managementportal 

select dg.ID from HSAA.Diagnosis dg
left join LinkTableData.FacilityFullList la on dg.ID=la .ID

InterSystems announces another developer preview release, as part of the developer preview program for the 2022.3. Many updates and enhancements have been added in 2022.3 and there are also brand new capabilities, such as the new FHIR SQL Builder, improvements for Columnar Storage, and support to Oracle Linux 9. Some of these features or improvements may not be available in this current developer preview.

Future preview releases are expected to be updated biweekly and we will add features as they are ready.

After seeing several article raving about how ground-breaking the recent release of ChatGPT is, I thought I would try asking it to help with a Caché newbie question:  How do you find the version of InterSystems Caché?

To be honest, I was quite surprised at what the chat bot told me:

Hi guys!

My student asked my why his unit tests don't work as they should, and I just could answer him. Here is the simplified case.

There is a class with a required unique property Name:

Class Test.NewClass [ Abstract ]
{
Property Name As %String [ Required ];
Index NameIndex On Name [ Unique ];
}

And there is an inherited class:

Class Test.NewClass1 Extends (%Persistent, Test.NewClass)
{
}

What I expect to happen, is when I save two objects of class Test.NewClass1 with the same value of property Name, for the second one to get an error stating that it violates the unique index.

Introduction {#Webinar:ImplementingIntegrationswith.NetorJava-Introduction}

InterSystems IRIS 2020.1 includes PEX (Production EXtension Framework) to facilitate the development of IRIS Interoperability productions with components written in Java or .NET.

Thanks to PEX, an integration developer with knowledge of Java or .NET can benefit from the power, scalability, and robustness of the InterSystems IRIS Interoperability framework and be productive in no time.

For an IRIS Interoperability framework expert, PEX makes it easy to enrich integrations with pre-existing Java- or .

I have a table, with autoincremented id

CREATE TABLE users (
    id SERIAL NOT NULL,
    name VARCHAR(30) NOT NULL,
    PRIMARY KEY (id)
)

I can add a new item there with an explicit id 

INSERT INTO users (id, name) VALUES (2, 'fred')

And while my id is autoincremented, I can omit it

INSERT INTO users (name) VALUES ('ed')

So, this time, I don't know the id, and I want to somehow get it.

I could do it with LAST_IDENTITY() function, but it just uses %RowID, and have no relation to the primary id

When creating a PRA (Privileged Routine Application; which by the way is not relevant just for Routines but also for Classes/Methods), it is important to make sure you include a new $ROLES, before calling AddRoles(). For example:

 new $ROLES
 set status=$System.Security.AddRoles("MyPrivilegedRoutineApplication")

This way you ensure that indeed the added (elevated) roles "evaporate" for the User running this code, once the User is out of the scope of that routine/method.

[Thank you @Andreas Dieckow for validating this]

Hello!

Not opening an instance by index key after CACHE migration to IRIS. In composite indices, when one of the values is null, when using idx open it does not return the reference.

Has anyone had this problem?

is Intersystems studio available for Linux?

The capacity of taking numerous records every second while also facilitating real-time queries simultaneously in real time is called Hybrid Transactional Analytical Processing (HTAP). It is also called Transactional analytics or Transanalytics or Translytics and is a very useful element in scenarios where there is constant flow of real time data coming from IIOT sensors or data on fluctuations in stock market, and supporting the need for querying these data sets in real-time or near real-time.

⏯ InterSystems IRIS Cloud SQL @ Global Summit 2022

Hello everyone,

I talked to a colleague and he said that at the other company he worked, they converted a routine into a line and used that in the terminal like a command. So, I want to know if we have this function native in Intersystems products, or maybe was a program they created, my colleague doesn't remember and this would be useful for me now.

Edit: 

Example of function:

func1  
  set var="Test"
  write var
  quit 0

Become a line command:

 USER>set var="Test" write var quit 0

Best Regards,
Flávio.

How do I delete these system tasks that are obsolete..  The task in the attached image has no possibility to delete... 

We have a UNIX VM with an InterSystems IRIS instance which we cloned for testing purposes, and we have found that $System (which is used for self-identification in email notifications) is still showing the hostname of the original VM, rather than the hostname of the cloned VM.  This is coming from $System.INetInfo.LocalHostHame().

Does anyone know what you need to change on a UNIX clone in order for it to display the appropriate new host name in $System?  

TL;DR: This article describes an introductory-level project that exercises some string-manipulation functions in both ObjectScript and Python…with specs from a song.

After you’ve written your first “Hello World!” program, are you ready for a new fun challenge?  An old, very popular (at the time) song may be just what you need.

While I was driving around on vacation in southern Maine, the local “Legends” radio station played the old classic, “The Name Game” by Shirley Ellis (https://www.youtube.com/watch?v=5MJLi5_dyn0).

Poor glycemic control is associated with a greater risk of miscarriage, NICU admission, operative delivery, and shorter gestational periods. Especially at risk are those with preexisting diabetes, who would benefit from maintaining near-normal glycemia before conception. All DIP patients would benefit from earlier referral to the diabetes service. Emphasis is placed on the early detection and effective treatment of DIP to achieve normoglycemia if associated complications, perinatal mortality, and maternal morbidity are to be reduced.

I know InterSystems has the SAP Java Connector.

Has anyone used that to communicate between IRIS and SAP S/4HANA Cloud? Or some other means?

Hi Community,

@José.Pereira and I want to introduce ZPM Explorer, our graphic interface to explorer the greats applications that we have inside InterSystems Package Manager.

The idea

ZPM Explorer's idea is to make it easier for people to find out what ZPM offers. Every week, every day, a new app joins the ZPM world, so why not help developers and non-developers take advantage of this incredible world?

Hi,
I wonder why IRIS seems to have its on way to deal with order or operations such as the example in the title. This affects regular arithmetic operations but of course conditions in various statements.

Even after years of COS development, I still get caught by these tiny frustrating details and it is absolutely annoying when you are writing APIs that some some maths.

Here is an example:

The last example is from here.

But, if you use any other calc:

Hi Developers!

Often when we develop some library, tool, package, whatever on InterSystems ObjectScript we have a question, how we deploy this package on the target machine?

Also, we often expect that some other libraries already installed, so our package depends on them, and often on some particular version of it.

When you code on javascript, python, etc the role of packages deployment with dependency management takes package manager.

So, I'm pleased to announce that InterSystems ObjectScript Package Manager available!

Hi Developers,

IntegratedML is a feature helps us and our teams easily implement machine learning (ML) without dedicated ML experts and data scientists. If you do not need particularly complex ML function, integratedML is a good choice and convenient that only requires executing 3 SQL queries to build predictive models directly from InterSystems IRIS to ML engine.

I have recorded a video that walk through the basic of IntegratedML and implement an application from open exchange called diseases predictor by @Yuri.

I got an error that occurs inside %CSP.Broker. That class is located inside %SYS namespace.

I tried lot of things (including checking system logs) but ultimately what would really help would be to be able to modify that class to add my own logs into it.

If I try to modify it, I got this error message: 

Item '%CSP.Broker' is mapped from a database that you do no have write permissions on.

What I also tried (but failed) : to create a new class outside %SYS namespace (eg: SomeNamespace.MyBroker) and copy code implementation of %CSP.Broker into that class (just changing name of the class).

I've been working for 19 years in the technology field, and on this journey, I was able to be part of several projects on numerous fronts; however, the health area is one of the areas that attract me the most.

So whenever we get a chance to create something focused on health, using the FHIR protocol is exciting.

But, a team of 3 IT guys with a tech background would not be enough to deliver something really useful, and for a topic as important as women's health, we brought to the team someone who really understands the subject.

 Hi Community:

Pleased to let you know that in Forrester's latest "Wave" report on analytical data platforms, we have been designated a "leader." 

You can learn more from this InterSystems Press Release, or even better, read The Forrester Wave™: Translytical Data Platforms, Q4 2022.

In our current UCR arhcitecture, we use two installations. We have one machine with Access, Registry and Edges and one machine with the ODS. On the machine with the Registry, I can create a user/clinician. When I log into the management portal with this user, a so-called delegated user is created in the cached users table. So far everything is going well. 

When I try the same on the machine with the ODS I get the message : 'ERROR #822: Access Denied' . so no delegated user is created.... Does anyone have any idea where I can find the solution?

Hi Friends,

I have created and exposed a web service for the given WSDL. 

daily 500+ requests are processed via this SOAP service in live.

after 2 days live server got stopped with no web sessions available.

We removed this SOAP service, now live is working fine. We are investigating why web sessions got increased.

Could you please give me any clue, as to why web sessions got increased with the unknown user while processing requests through SOAP service?

Thanks,

Prashanth
