🗣 Multi-Inheritance in a Multi-Model Environment

Hello Wonderful Community!

The question I have is: 

Can we set a Call Alert instead of an email alert (or both) in Ensemble when the system goes down? 

The message below is what we got via email. But I wanted to know if there is more functionality that allows to use a call system.

Subject: [CACHE SEVERE ERROR] Failed to allocate 43322MB shared memory using Huge Pages. Startup will retry with standard pages. If huge pages are needed for performance, check the OS settings and consider marking them as required with th.

Please can I have a quick simple answer.

I am still learning.

Thank-you.

I have SQLCompute with SQLComputeCode on a couple of Properties in my class.

These work fin when I insert/update via ObjectScript or SQL from the ManagementPortal.

However, if I insert (create new record) via my C# app using the Caché ODBC DLL the SQLCompute is ignored, it does not run.

Is this expected InterSystems Caché behaviour? We are on latest IRIS platform.

I'm pleased to announce the latest version of extensions for ObjectScript. Just a month has gone since my latest update, and I already have something new to show.

Important. In this version connection to the server will be disabled by default. You have to activate connection through the settings:"objectscript.conn.active" = true.

Hi All - Been looking in the documentation to see if, in DeepSee->Analyzer there's a way to create a filter on the "Most" recent date in a dimension.    The filter affords the ability to choose "Now" but sometime the most recent date in the data was a week ago.

Currently, many of you has some knowledge about CachéQuality (which is being renamed to objectscriptQuality) for analyzing objectscript code using the rules we have predefined. Probably you have tested it and have found too many warnings in your projects. I'm sure there are issues which are really important for you and some others which you would like to dismiss.

We have more than 90 rules to test different code situations and warn about a problem or a possible bug in code.

Hello everyone,

I am searching, but i cannot find a way to call a Procedure in Caché with PHP. Using .NET we have the Intersystems.Data.CacheClient.CacheCommand and we make a call in a Procedure. How i can do the same in PHP?

Regards,
Flávio

InterSystems has corrected a defect that can cause shadowing to fail with an access violation. In rare cases, the defect can cause memory corruption, leading to unpredictable behavior. 

Note: The defect does not affect mirroring.

This defect affects:

• InterSystems IRIS 2019.1.1 and 2019.3
• IRIS for Health 2019.1.1 and 2019.3
• HealthShare Health Connect 2019.1.1
• HealthShare Health Connect (HSAP) 15.032 on 2018.1.3
• Caché and Ensemble 2018.1.

In time for InterSystems Global Summit 2019 we at George James Software are pleased to offer a cloud-hosted evaluation environment where you can work with Serenji in Visual Studio Code, editing and debugging ObjectScript in a sandbox running InterSystems IRIS 2019.3 Community edition.

You can do it all from your web browser. Nothing will be installed on your workstation, nor will any settings have to be changed on it.

To take Serenji for a test drive please visit https://georgejames.com/dc-gitpod

Some time ago I developed an application that tackled a familarial problem faced by many developers when required to update multiple UAT or PRODUCTION sites with the latest Software patches that have been developed and tested on your DEV server and now need to be deployed to multiple sites running that software.

Hi I am experienced with Ensemble but working in my first DeepSee project, so forgive me if this seems elementary. 

My question is, how do I clear  the data out? Every time I build I am adding more and more data. But I would like to revert my cube to being 0 so I can reload it and start over? Set my row count back to 0?

I am unable to remove/purge through the management portal

-I've tried to kill my cube Do ##class(%DeepSee.Utils).%KillCube("MyCube.Cube")  and then Rebuild it. 

Thanks In advance

Hello community,

I have a very simple REST API connection doing a POST of JSON messages via AZURE APIM. 

It worked successfully for few weeks until a day ago when i started receiving a bad response as below.

<META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"><meta name="format-detection" content="telephone=no"><meta name="viewport" content="initial-scale=1.0"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><script type="text/javascript" src="/_Incapsula_Resource?

InterSystems Data Platforms products allow you to export and import security settings in two different ways.

This article talks about those options:

• On the command line, using ^SECURITY
• Programmatically, using the Export and Import methods of classes in the Security package

Exporting settings on the command line (^SECURITY)

You can export everything or individual sections of the security settings.

Exporting everything with ^SECURITY

With ^SECURITY, you can export or import all the security settings for an instance very simply.

This quick guide shows how to serve HTTPS requests with InterSystems API Management. Advantage here is that you have your certs on one separated server and you don't need to configure each backend web-server separately.

Here's how:

1. Buy the domain name.

2. Adjust DNS records from your domain to the IAM IP address.

3. Generate HTTPS certificate and private key. I use Let's Encrypt - it's free.

4. Start IAM if you didn't already.

5. Send this request to IAM:

POST http://host:8001/certificates/
{
    "cert": "-----BEGIN CERTIFICATE-----.

Recently I was fielding some questions that someone had about some bugs that crop up on Docker for Mac, and it reminded me of what Shakespeare wrote in his famous tragedy about large-scale software orchestration, Kubelet: the Prince of Benchmark.

When running Docker on Mac or Windows, some problems crop up occasionally, because Docker for Mac and Docker for Windows are both using some clever and mostly-hidden tricks to be able to run at all.  Containers are, fundamentally, a Linux technology, cobbled together from a handful of features native to the Linux platform.

We have a SOAP web service that we call to retrieve a stream of a PDF file. The web service is written by another group in our company (not a Cache group). We are running into one issue where it seems that the PDF is too big and when it is sent to us we get this "ERROR #6301: SAX XML Parser Error: <STORE>". The stream is about 8mb. This is the first time that we have encountered this issue.

We have a WRC ticket open about this but doing some research, we found that if we increase the $ZSTORAGE then we no longer get this error when we call the web service for this 8mb file.

Introduction

We used the InterSystems iKnow technology to create a review assessment system called iKnow Reviews Analyzer (iKRA). Some information about the prototype of the system can be found here. iKRA analyzes users’ text reviews and automatically rates the object being reviewed. This functionality may come in very handy on e-commerce sites, forums or collections of media content – in other words, everywhere where people discuss products, places or services, for example.

What does the solution do?

I would like to control multiple 'services' in Ensemble.

I would like the ability to switch them off and on.

My plan is to achieve this in a Cache class using ObjectScript.

Is this possible?

Any tips, starting points would be gratefully received.

Many thanks.,

Hello InterSystems Community,

We're excited to announce that we've completed our first Open Exchange submission for InterSystems platforms.

BridgeWorks VDM is an ad hoc reporting and graphical SQL query builder application that was designed for any user who needs access to their SQL projections in InterSystems Caché, InterSystems IRIS, InterSystems IRIS for Health databases as well as access to InterSystems DeepSee and InterSystems IRIS BI Cubes with minimal SQL scripting experience.

How do I best create a filter in DeepSee to restrict query results for the current login, that is where the results are filtered by a Dimension compared to the ObjectScript special variable $USERNAME or an ObjectScript expression that restricts what the current user is allowed to see?

Hi everyone. I'm new to cache, and i  was looking for a command who reads a .txt file and store the informations in variables. I've found on the documentation the EnsLib.SQL.SNapshot class, and, even if i'm not sure if that's what i need, when i run the code it says that the class doesn't exist, but i couldn't find the right superclass to extend.

Easily transform a CSV file into a personalized preview of DeepSee - InterSystems BI

AnalyzeThis can be found on InterSystems Open Exchange. Use the Download link to navigate to GitHub and begin installing the project. Follow the “Installation” section of the GitHub README.

InterSystems IRIS supports a unique data structure, called globals, for information storage. Essentially, globals are persistent arrays with multi-level indices, having several extra capabilities—transactions, quick traversal of tree structures, and a programming language known as ObjectScript.

I'd note that for the remainder of the article, or at least the code samples, we'll assume you have familiarised yourself with the basics of globals:

Globals Are Magic Swords For Managing Data. Part 1.
Globals - Magic swords for storing data. Trees. Part 2.
Globals - Magic swords for storing data.

Hello Everyone,

I'm want to know, what is more common for your company to use, the abbreviation syntax or the complety name of commands, and why?

Ex. 

S VAR=10 / D FUNC^ROUTINE F 1:1:1000

Set VAR=10 / Do Func^Routine / For 1:1:1000

set var=10 / do func^routine / for 1:1:1000

Here in my company, we are familiar with the abbreviation syntax, because to spell is more faster.

Hi developers!

I just want to share with you the knowledge aka experience which could save you a few hours someday. 

If you are building REST API with IRIS which contains more than 1 level of "/", e.g. '/patients/all'  don't forget to add parameter 'recurse=1' into your deployment script in %Installer, otherwise all the second and higher entries won't work. And all the entries of level=1 will work.

/patients

- will work,  but

/patients/all

- won't.  

Here is an example of CSPApplicatoin section which fix the issue and which you may want to use in your %Installer class:

    <CSPApplication Url="${CSPAPP}"
      Recurse="1"
      Directory="${CSPAPPDIR}"
      Grant="${RESOURCE},%SQL"
      AuthenticationMethods="96"
      />

Hi, 

I'm currently unable to change my First Name from my account page.

Although my name is Thomas, I go by Joe.

Is there a reason I'm not able to edit my displayed name?

How can I change this?

First webinar on  InterSystems API Management!

We are pleased to invite you to the upcoming webinar in Russian: Introduction to InterSystems API Management on November 21 at 10:00 Moscow time (GMT+3)!

As you might have heard, we recently introduced the InterSystems API Manager (IAM) - a new feature of the InterSystems IRIS Data Platform,
enabling you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure.

In this webinar I will highlight some of the many capabilities IAM allows you to leverage. InterSystems API Manager brings everything you need:

• to monitor your HTTP-based API traffic and understand who is using your APIs; what are your most popular APIs and which could require a rework.
• to control who is using your APIs and restrict usage in various ways. From simple access restrictions to throttling API traffic and fine-tuning request payloads, you have fine-grained control and can react quickly.
• to protect your APIs with central security mechanisms like OAuth2.0 or Key Token Authentication.
• to onboard third-party developers and provide them with a superb developer experience right from the start by providing a dedicated Developer Portal for their needs.
• to scale your API demands and deliver low-latency responses

There would be a live demo.

This webinar is for System Architects, Developers and DevOps Engineers.
Time: November 21 at 10:00 Moscow time (GMT+3)!

The language of the webinar is Russian.

Register!

Cache Running version:
Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.1.1 (Build 111U_SU) Tue May 23 2017 13:39:47 EDT

The frequency with which the journal is synced depends on the operating circumstances of the InterSystems IRIS instance involved. A journal sync can be triggered:

• Once every two (2) seconds if the system is idle.
• In an ECP-based distributed cache cluster, by the data server when responding to specific requests (for example, $Increment) from the application servers to guarantee ECP semantics.
