Your application is deployed and everything is running fine. Great, hi-five! Then out of the blue the phone starts to ring off the hook – it’s users complaining that the application is sometimes ‘slow’. But what does that mean? Sometimes? What tools do you have and what statistics should you be looking at to find and resolve this slowness? Is your system infrastructure up to the task of the user load? What infrastructure design questions should you have asked before you went into production? How can you capacity plan for new hardware with confidence and without over-spec'ing? How can you stop the phone ringing? How could you have stopped it ringing in the first place?

Say I have an ObjectScript object called Book. It has 2 properties title and author. It extends JSON.%Adaptor, so I can call book.%JSONExport() and get this output:

{ "title": "For Whom the Bell Tolls", "author": "Hemmingway" }

In my web service I want to have a search function that returns an array of Books along with the total number of responses, like this:

Hi,

An exception occurs randomly.
I expect the value of ^TEST to be 20, but it's not.
Did i miss something like closing, flush the stream or locking the global?

Hi,

What is a Foundation Production and what does it do?

We are currently on HealthShare Health Connect 15.03 and we are starting the process of moving to HealthShare Health Connect 2019.1.

The 2019.1 Installation Guide is pretty clear that it is essential, but I'm having trouble working out exactly what it does?

Leading on from this is what should I call it?

From the installation guide:

I have successfully created REST service classes on my local IRIS server following this book: Using the /api/mgmnt/ Service | Creating REST Services | InterSystems IRIS Data Platform 2021.2

I am now 1) trying to edit impl.cls in VS Code and 2) export it to my local repo so I can push to the remote repo.

When I click on my project in VS Code and 'Add to project' and choose the new package, spec.cls and impl.cls, I get the following error:

What is Web Scraping:

In simple terms, Web scraping, web harvesting, or web data extraction is an automated process of collecting large data(unstructured) from websites. The user can extract all the data on particular sites or the specific data as per the requirement. The data collected can be stored in a structured format for further analysis.

Hi all, New user here. I have an instance of Google Cloud Iris Health Community Edition running and am logged in on terminal. I follow the instructions for Google Cloud IRIS Health Community Edition. How do I get to iris? iris status yields nothing, there is no /bin/iris and sudo docker ps -a shows no containers but there probably is a iris container somewhere on the instance? 'Visit the site' yields ERR_CONNECTION_REFUSED

Hello community! I'm working on an internal innovation effort at InterSystems considering our documentation/resources around upgrades. As part of this, I'd love to have your answers to any/all of the following questions, either via comment or (if you prefer your answers to be more private) direct message.

Thanks in advance!

What InterSystems products + versions are you running? ($zv is ideal.)

What makes you decide to upgrade?

What are your blockers to upgrading?

What is your process for evaluating and planning a possible upgrade?

Is there a way to compare the content of two variables/ lists and if they share a common element/ value return 1?

Example the two below both have "Yellow":

Set y = "Red, Green, Orange, Yellow"

Set x = "Purple, Black, Yellow, Pink"

The lists I am working with have over 30 elements/values that vary so it is difficult to hard code it to say look for "Yellow".

Quite a complex scenario we are trying to solve but should be able to understand.

We're developing a task executer that runs on a server with a certain timezone.

The tasks run every day at a defined time, but in different timezones.

We're saving in database at what time we want to execute the task, and in what timezone (don't go to the save in UTC pitfall, as with DST it will be at different times)

What I want to do if when opening a task from the database, convert 02:00 Europe/Madrid, either to UTC or to local (server) time.

Hi,
For a REST application, when a user connects, I have to write a message in an application log.
The login is processed by the /login routine by default.

How can I add a process to the login process?
Is there a callback ?
Should I create a login method in my class that extends %CSP.REST ?
I'm not sure and can't find information in the documentation ?

I try this (not working) :

<Routes>

<Route Url="/lists" Method="GET" Call="GetLists" />

<Route Url="/me" Method="GET" Call="GetUserInformations" />

  • June-July - InterSystems IRIS AI/ML solutions. IntegratedML as a bonus
  • August - InterSystems IRIS for Health FHIR application
  • September - InterSystems IRIS Full-stack application: IRIS as a server and UI on any framework and any form: and web, desktop, mobile UI
  • October - Interoperability solutions for InterSystems IRIS and InterSystems IRIS for Health
  • November - Analytics Solution using InterSystems IRIS

Hi, I was wondering if anyone already dealt with this issue:
"System has been suspended for over X seconds, exceeding the maximum duration specified. Allowing system activity to resume. Any ongoing backup has presumably failed. Next InterSystems IRIS backup must be a full one"

our backup system "Commvault" is automatic, how do you tell it once you get this message that the next backup should be full?

thanks,

Eyal

HL7 test message generator

I am looking for an appropriate solution to generate HL7 test messages to test my production. IRIS for Health already contains many HL7 specific functions like the schema structures. Furthermore one can use transformations to build custom messages.

What I am interested in is if anyone has already created a tool or script that can be used to create any HL7 messages that meet the minimum requirements and populate all the required fields with test values. I would then like to send these test messages via TCP to a business service.

Hello All,

I am just wondering if there is any inbuilt function or utility available in IRIS to clean up "null" elements from JSON e.g. I want to remove "null" elements from payload below before I do any processing with it.

{

recipients: [

{ "name":"Utsavi", "email":"utsavi@gmail.com"},

{ "name":"Utsavi 1", "email":"utsavi1@gmail.com"},

null, null

],

content:[null, {"title":"Test.pdf", "data":"ygwehfbnwfbhew"} ]

}

Thanks & Regards,

In the last post we scheduled 24-hour collections of performance metrics using pButtons. In this post we are going to be looking at a few of the key metrics that are being collected and how they relate to the underlying system hardware. We will also start to explore the relationship between Caché (or any of the InterSystems Data Platforms) metrics and system metrics. And how you can use these metrics to understand the daily beat rate of your systems and diagnose performance problems.
