I would like to access discarded messages from a specfic process, is there any method that allows for this?

Alternatively what table holds this info so I can query it?

Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in October 2022:

Hi,

I have installed Visual Studio on my PC and connecting to IRIS on my Linux server.

I have installed the InterSystems extensions.

I click on the InterSystems icon on left->Click on "Choose Server and Namespace" -> Pick my server myTrak.

However I get this error:
request to https://mytrak:52773/api/atelier/ failed,
 reason: write EPROTO 18648712:error:100000f7:SSL routines:OPENSSL_internal: WRONG_VERSION_NUMBER:../../third_party/boringssl/src/ssl/tls_record.cc:242:

Does anyone know how to fix this?

Hi

Can anyone explain how to display custom icons in a TablePane?

Recently there was an internal email thread on which SMTP server to use in demos. I thought I'd share the comments from that thread:

• Person 1: I tried gmail  (smtp.gmail.com, port 465) this morning, it works fine.
  To use gmail, you must enable 2-step verification for your google account and generate App password. https://support.google.com/mail/answer/185833?hl=en

• Person 2:  I use https://www.hmailserver.com 

• Person 3: I, too, use hMailServer as a local SMTP server on my demo VMs, with a mail client (usually Outlook) also on the VM. So no need to connect out to an SMTP server on the Internet.

Can you get a boolean response in the same way you can with a Business component using  ##class(Ens.Director).IsItemEnabled(component).

Or even use this method for getting the adapter state?

Hi Guys,

I've a task scheduler that is stuck in Running is there a way for force stopping it?

Thanks

Hi Community,

I am working on sending Gmail with error details when any errors occurs in the ensemble production.

1.I have Ens.Alert (Business process) using the class Ens.Alerting.AlertManager and Emailoperation (Business operation) using the class EnsLib.EMail.AlertOperation. here my business process is not sending the Alarm request to business operation eventhough i am using rule to connect the business operation 

2.What are SMTP server details needs to given for Gmail?

Please let me know how to resolve these issues

Hi,

I want to know how to add a class to IRIS namespace 'USER' using terminal.

How do I do this?

I know you can add this class using Visual Studio Code with the Intersystems extension installed on my PC and connected to an IRIS instance.

Is it possible to do this with terminal? From this prompt:
BASETC:USER>

I have a class like in this example:

Class ObjectScript.RightTriangle
{

/// Compute area and hypotenuse of a right triangle
ClassMethod Main()
{
    write !, "Compute the area and hypotenuse of a right triangle",
          !, "given the lengths of its two sides."
    ....
}
}

Hi Team,

How InterSystems cache calculate the license count based on process?

How to we determine the product required license count ?

Thanks

Hi, I have a laptop with a Core i5 processor, a workstation with AMD Athlon 3000G processor, and another workstation with AMD Ryzen 3900 onboard. I was succeded to install IRIS Health community on the laptop. On both AMD workstations the install process hangs. I've waited for 8 hours but with no avail. What could be wrong with AMD?

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)
)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');

Hi, devs!

In ObjectScript I can refer to a class parameter as:

write ..#ParameterName

How do I do the same in Embedded Python?

Hi,

I would like to use the XML Schema Wizard / %XML.Utils.SchemaReader to generate the Cache classes.

It seems Xerces has trouble with xs:import. XSD Source - DMP_Rheumatoide_Arthritis.xsd

Fehler: FEHLER #5373: Klasse 'DMP.cda.dmpclinicaldocumentheadertyp', von 'DMP.cda.levelone:property:clinicaldocumentheader' benutzt, existiert nicht
Abgeschlossen bei 2022-11-05 22:17:18

Maybe I can solve this problem by enabling this feature in Xerces somehow?

Is there any other way to work around this problem?

Best regards

Hi, The IRIS Health Docker image comes with Java 1.8 but I need OpenJDK 11. How could I install that using aptitude or somehow else? The apt-get command requires elevation but if I rewrite the command with sudo apt-get it won't build with error message /bin/sh: sudo: not found Is it possible to do what I want?

Hey Developers!

Watch this video to get a brief overview of the InterSystems API Manager (IAM) and a deeper dive into new features of IAM 2.3 and 2.8:

⏯ API Management with InterSystems IRIS @ Global Summit 2022

Introduction

This article aims to give an introduction to what gRPC is and an example of how to play with the official Hello World using IRIS Embedded Python.

You can find all the code exposed here, in this project repo.

gRPC

The gRPC (gRPC remote procedure call) is an API architectural style based on the RPC protocol. The project was created by Google in 2015 and is licensed under Apache 2.0. Currently, the project is supported by the Cloud Native Computing Foundation (CNCF).

** Revised Feb-12, 2018

While this article is about InterSystems IRIS, it also applies to Caché, Ensemble, and HealthShare distributions.

Introduction

Memory is managed in pages.  The default page size is 4KB on Linux systems.  Red Hat Enterprise Linux 6, SUSE Linux Enterprise Server 11, and Oracle Linux 6 introduced a method to provide an increased page size in 2MB or 1GB sizes depending on system configuration know as HugePages.

At first HugePages required to be assigned at boot time, and if not managed or calculated appropriately could result in wasted resources.  As a result various Linux distributions introduced Transparent HugePages with the 2.6.38 kernel as enabled by default.  This was meant as a means to automate creating, managing, and using HugePages.  Prior kernel versions may have this feature as well however may not be marked as [always] and potentially set to [madvise].  

Transparent Huge Pages (THP) is a Linux memory management system that reduces the overhead of Translation Lookaside Buffer (TLB) lookups on machines with large amounts of memory by using larger memory pages.  However in current Linux releases THP can only map individual process heap and stack space.

Thank you to everyone who joined our User Group Session yesterday!

It was great showing off the new Deltanji Production Component driver that facilitates source control of interoperability productions, and we had some really insightful discussions as well.

If you missed out on the session and would like a copy of the recording, feel free to drop me a message. 

Hi 

I have a  Zen Page with tablepane which has a datasource in a different namespace to that of the Zen Page. When the page is run, no data is returned and the tablepane is not populate,  even though the rerferenced table contains dat.

The tablePane code is as follows:

<tablePane id="DataExtractionCurrent"
	showZebra="true"
	cellSpacing="2px"
	OnCreateResultSet="DataExtractionCurrent">
</tablePane>

The OnCreateResultSet points to the following method:

Method DataExtractionCurrent(Output tSC As %Status, pInfo As %ZEN.Auxiliary.

In this article, I would show how you can upload and download files from InterSystems products via http.

The questions about working with files over http arise fairly often on community and I'm usually linking to my FileServer project which demonstrates file upload/download but I'd like to talk a bit more on how we can serve and receive files from InterSystems products.

I was able to run the Cache terminal from the command prompt with the following command, in the namespace that I provided in the brackets:

cterm /console=cn_ap:ENSEMBLE[TEST_1]
But the command suddenly stopped opening the terminal in the correct namespace. It just opens it in the default namespace. I tried it with different namespaces or invalid namespaces, it always opens the terminal in the default namespace now.

I cannot figure out what is causing this behaviour.
