All time

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

Creating a PEX Business Operation

PEX is a new InterSystems IRIS feature to allows extends IRIS with existent features from Java or .NET.

It is possible create interoperability inbound and outbound adapters, business services (integrate from external to internal) and operations (integrate internal to external).

To create a PEX component it is necessary import .NET (InterSystems.EnsLib.PEX.*) or Java (com.intersystems.enslib.pex.*) packages and extends or implements the properly class.

Hi Developers!
Let me share with you some exercises from a workshop about developing interoperability components in Java using PEX (Production EXtension).

You will find slides and step by step exercises about:

  • Understanding simple PEX components coded in Java.
  • Making some changes on them.

All built using containers, so you don't need to build a local Java environment.

I have just started to experiment with Using IRIS in Docker.

My first objective was to be able to enable global persistence within a Docker container. Using the following command I have managed to achieve this:

docker run --detach --publish 52773:52773 --volume /data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 store/intersystems/iris-community:2020.1.0.199.0

Within this container, I have created a simple global:

for i=1:1:10 set ^tmp(i)=""

Routing Rule Usage -

Can we use Functions and Methods with multiple parameters and refer objects by reference as parameters inside Routing rule ?

How do we handle DB related workflows in Business Rules ?
How can we perform Response object based handling in Business Rules ?
Can we try by extending methods with Ens.Util.FunctionSet and pass in the Context object from the rule as a parameter for certain functions ?
Can we split the Business Operations into methods that can be used from the routing rules and create the message route request flow ?

Hi all,

For special definition of the company, we need to define a PoolSize according to the environment that the "Ensemble" is working.

So the first try as been add the parameter into "System Default Setting"

However, this parameter is not available in "Setting default values" in Setting tab.

I've opened the code of my production and I've noted that this parameter is a attribute of the XML element of this item

As you have seen in the latest community publications, InterSystems IRIS has included since version 2024.1 the possibility of including vector data types in its database and based on this type of data vector searches have been implemented. Well, these new features reminded me of the article I published a while ago that was based on facial recognition using Embedded Python.

Hi all,

Do you know if there is a way to create a Lock that is related to an existing transaction, in the sense that if transaction is finished (commit or rollback) Lock is removed. I ask this because in the following example Lock is there until process is killed.

Example :

TSTART

Lock +^MyLock

TROLLBACK

I know, that, Caché itself is locking internally a table register when doing an OpenId with exclusive flag during the transaction life. For example :

TSTART

This is a series of programming challenges for beginners and experienced Caché programmers.

For an introduction : goto to article https://community.intersystems.com/post/advent-code-2016-day1-no-time-ta...

The input in today's challenge consists of an encrypted name, a dash, a sectorID, a dash and a checksum between brackets.
A name is real if the checksum is equal to the five most common letters in the encypted name.

"SELECT %SYSTEM.SQL_TableExists('table name') "could work as expected under SQL shell,

but for "CALL %SYSTEM.SQL_TableExists('table name')" does not work (not any error reported, it just show nothing).

Is there any reason why CALL could not be applied to a stored procedure?

Thanks.

Hi Community,

This post is a introduction of my open exchange iris-climate-change application.

iris-climate-change web application Imports The Food and Agriculture Organization (FAO) Climate Change dataset by using LOAD DATA (SQL) functionality and analyze and visualize data with the help of Python Flask Web Framework, Pandas Python data analysis Library, Plotly Open Source Graphing Library for Python and Plotly JavaScript Open Source Graphing Library.

Hi There,

I'm fairly new to ObjectScript/Ensemble and I'm sure I may be fundamentally misunderstanding how the %JSONImport/%JSONExport and XDATA mapping work and I was hoping you good folks could help me out. I'm essentially trying to create an object that I can use to translate from one JSON schema to another.

First my class:

%XML.Reader Limitations

Hi all,

Are there limitations to the size of a file or stream that %XML.Reader will parse?

I am trying to parse a large, 573MB, XML file using either the 'OpenFile' or 'OpenStream' methods, but both return errors.

When I try to use the 'OpenStream' method I get a 'ERROR #6301: SAX XML Parser Error: input ended before all started tags were ended' error',

and when I try the 'OpenFile' method I get a 'ERROR #6301: SAX XML Parser Error: <STORE>'.

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Hi!

we are evaluating IRIS Data Platform as an OAuth2 Authorization Server with the use of the official Docker image. We currently struggle with the OAuth2 setup, as we are required to use https:// for the /oauth2/authorize and /oauth2/token endpoints, but the Docker container exposes only http:// in its default configuration. We have tried to find any hints in the docs but were not successful. Any help is appreciated.

Thanks

Klaus & Lukas
