1. Export API

a. Use $system.OBJ.Export() to specify individual routines to export. For example:

The format to specify is routine name.extension, and the extension is mac, bas, int, inc, obj.

Errors during export are stored in errors.

Using the Config.Configuration class and SYS.Database class methods, you can create and register a namespace database from the terminal.

Below is a series of execution examples that create database file /CacheDB/AAA/cache.dat and register database AAA and namespace AAA in the configuration file (cache.cpf).
* Execute in the %SYS namespace. *

* Make sure that this script runs as the user that is used for all IRIS processes to ensure that the directory has appropriate ownership and permissions *

Hi Dev Community members,

In this post, we would like to show you how to use DC tags. Let's make the most of this Developer Community option!

In this brief article I would like to share a few strategies to run objectscript code in debug mode.

How to enter debug mode

There are two ways to launch the debugger.

Launching a command

Let's suppose that we have to debug the following method

contains important system processes.
* Please refer to the attachment for how to check important system processes that should be monitored.

Hi Devs!

For me, one of the most painful things about ObjectScript is ##class(Class).Method() typing to call a class method in code or in a terminal. I even submitted an idea to simplify it in ObjectScript.

But! There is a new feature in VSCode ObjectScript that was just introduced to the plugin - Copy Invocation!

In this article, we will introduce how to deal with the situation: "I accidentally deleted a global!"

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

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,

Tired of entering login-password during the docker build with your InterSystems IRIS every time?

There is a handy way to turn it on and off – use the passwordless zpm module.

Watch this video to explore how to use the passwordless ipm module to turn on and off entering login-password during docker build with your InterSystems IRIS:

The last days I've work with the great new feature: LOAD DATA With this post I would like to share my first experiences with you. The following points do not contain any order or other evaluation. These are only things that I noticed when using the LOAD DATA command. It should also be noted that these points are based on the IRIS Version 2021.2.0.617 which is a preview release. So it may be that my observations do not apply to newer IRIS versions.

The similarity between JSON objects + arrays and Globals in IRIS or Caché is evident.
With small and medium size JSON objects navigation across %Dynamic Objects is comfortable.
But with large and/or deep cascaded objects it becomes a challenge.

The presented tool offers 3 variants

• loading an already existing %Dyamic object or Array into a global of your choice
• loading a %Stream containing a JSON object into a global of your choice
• loading an external File containing a JSON object into a global of your choice

When creating a PRA (Privileged Routine Application; which by the way is not relevant just for Routines but also for Classes/Methods), it is important to make sure you include a new $ROLES, before calling

The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches.
