Hi developers!

Want to share with you an exercise I tried with InterSystems IRIS Interoperability.

The sample shows how to use IRIS Interoperability with data transformation component to change the data in CSV file.

The story is below.

InterSystems IRIS 2020.1 brings a broad set of improved and new capabilities to help build important applications. In addition to the many significant performance improvements accrued through 2019.1 and 2020.1, we are introducing one of our biggest changes in recent SQL history: the Universal Query Cache. This article provides more context on its impact to SQL-based applications at a technical level.

Doing a new project with %JSON.Adaptor, unexpectedly realized that %JSON.Adaptor does not support export to native JSON. %JSONExport just outputs directly to the current device, and there are two more methods %JSONExportToString, and %JSONExportToStream.

In conjunction with generating REST from swagger specification, where any generated method accepts as a result %DynamicObject, which is good.

I have multiple places in my REST where I have to return JSON for an object, but I have to modify the result a bit, just extend it with some other way.

In this article we are going to show the results of the comparision between IRIS and Postgress when handling Astronomy data.

Introduction

Since the earliest days of human civilization we have been fascinated by the sky at night. There are so many stars! Everybody has dreamed about them and fantasized about life in other planets.

Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?

InterSystems has decided to stop further development of the InterSystems IRIS Natural Language Processing, formerly known as iKnow, technology and label it as deprecated as of the 2023.3 release of InterSystems IRIS. InterSystems will continue to support existing customers using the technology, but does not recommend starting new development projects outside of the core text exploration use cases it was originally designed for.

In a fresh IRIS Community Edition container if we create a new Database and after we create a new Namespace enabling it for interoperability then we will see the message "ERROR #68: the mounted database count exceeds license limit"

The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.

Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.

Regarding the migration from old gateway to new $system.external interface the documentation says:

Hi Developers,

Watch the new video on InterSystems Developers YouTube to learn how to develop with InterSystems ObjectScript using the Visual Studio Code plug-in.

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

If you are seeing this error during import: ERROR #6301 Line: 2 Offset: 118 This does not appear to be a Cache exported file, unable to import.

This error is caused by exporting from InterSystems IRIS and trying to import into Caché. If you plan on exporting from IRIS to Caché, you can use the following qualifier to export your classes so that Caché does not throw an error on import:

w $SYSTEM.OBJ.Export(<items>,<filename>,"/exportversion=cache2018.1")

Hey Community,

New video is already waiting on InterSystems Developers YouTube:

Hi Community!

Do you know how to create workflow users and roles programmatically?
I use Docker for test deploy and I need to set up IRIS Interoperability using the install script.

Maybe do you know how to import/export already existing workflow users and roles?

InterSystems FAQ rubric

A tool (^GLOBUFF utility) is available to check the database cache usage for each global variable.

You can run the utility directly or programmatically in the %SYS namespace.

Here's how to run the utility directly:
