#InterSystems IRIS

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.

Hi Community! 
Today I'd like to share with you a link to some exercises from a workshop about developing REST APIs and how to manage them using InterSystems API Manager.

It includes step by step exercises to:

I'm participating in the Developing with InterSystems Objects and SQL with Joel Salomon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 1:

A question came up in the InterSystems developer community concerning the possibility of

Hi developers.
I often miss the ZPM program on a clean system.
Nothing complicated? Take and install.
And in one line? Especially in a docker container.
There is a solution. I'm very happy with it;)
Maybe the line can be shortened?

When using "IDENTITY" as my primary key, I can select the last inserted ID with 

SELECT LAST_IDENTITY() FROM %TSQL_sys.snf;

Actually this is how Hibernate + Iris' Driver acquires the inserted ID when mapping with

@GeneratedValue(strategy = GenerationType.IDENTITY)

Now, considering that I am using the type "SERIAL" as my primary key instead, how can I get the last inserted ID?

Note that with "SERIAL" I can forcefully insert any value for this ID, from which Iris will continue generating values...

There are many options to do a full security scan in your docker images, the most popular option is Anchore community edition.

Anchore will use the main public vulnerabilities databases available, including CVE.

To install Anchore is very ease (source: https://engine.anchore.io/docs/quickstart/), follow the steps:

When I create a TASK on the Primary mirror member and Try to create the same TASK in the backup mirror member,  It Gives me CSP Application error.

The TASK gets created in the Primary node without any errors and When creating in the Backup node it prompts the error.

It happens is IRIS and I didn't face this in CACHE.

Finally what I did is export the TASK in Primary and Imported in Backup.

Is this a feature of IRIS?

Hey Developers,

See how you can use InterSystems IRIS and Alteryx together to provide analytics and insights to your users.

⏯ Using InterSystems IRIS and Alteryx

As you know ObjectScript has no FOREACH system command nor system function.
But it has a wide room for creativity.

The task is to loop over a global or local array and do something FOR EACH element.

There are 2 possible solutions:
- creating a macro that generates the required code sequences
- creating an Extended Command to perform the action.

SQL, Objects, REST, and GraphQL

Introduction

We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills? 

There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:

Since some months ago we automatized source code analysis for projects on Github, so anyone with an open source project can have its code analyzed with no cost.

You only need to create the file ".github/workflows/objectscript-quality.yml" in your project with following contents:

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

Inspired by  @Evgeny Shvarov  and his recent article 
Deploying InterSystems IRIS Embedded Python Solutions with ZPM Package Manager
I propagated the idea forward to do the same also for modules in Node.js.
The case is based on my example of IRIS Native API for Node.js.

To anticipate the obvious reply that InterSystems IRIS supports WebSockets natively as a client:
This is correct and here is my aged related article with the link to the example in OEX
