#Globals

8

Globals are multidimensional sparse arrays which are stored in InterSystems Data Platform. Everything in InterSystems Products is stored in Globals: Classes, Tables, Documents, Code.

Documentation.

Is the default language (i.e., $$$DefaultLanguage, which is used as the basis for localization with $$$Text/etc. at compile time) always "en" for new Caché installations, or could it be different? How is this determined? I don't see an option to select a language during Caché installation.

Also, is there a supported/preferred API for setting the default language? Looking at %occMessages.inc, one option would be:

Holiday Reading: What Lies Beneath!

For those of you who might be new to IRIS, and even those who have used Cache or IRIS for some time but want to explore beyond its usually-assumed boundaries and practices, you might want to dive into this detailed exploration of the database engine that is at its heart, and discover just what you can really do with it, going way beyond what InterSystems have done with it for you.

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Hi developers!

As you probably noticed in IRIS 2021 the names of globals are random.

And if you create IRIS classes with DDL and want to be sure what global was created you probably would want to provide a name.

And indeed you can do it.

Use WITH %CLASSPARAMETER DEFAULTGLOBAL='^GLobalName' in CREATE Table to make it work. Documentation. See the example below:

CRUD-GLOBALS-IRISNATIVEAPI-JAVA

Hi All,

I am writing this article to tell about the application "CRUD-GLOBALS-IRISNATIVEAPI-JAVA" which is developed as part of "InterSystems IRIS Native API programming contest". The intention of this application is to manage the Globals which are in IRIS instance through java program using IRIS Native API. To use this application basic knowledge of CACHE Globals structure is required.

In this application as of now we have options to Create,View Globals and Data Search in Globals. Update and Delete will be added in next releases.

GlobalToJSON-embeddedPython-pure

I have created a package to export a Global into JSON object file and to re-create it by reloading from this file
embeddedPython refers to the new available technologies. It should be understood as a learning exercise of
how to handle the language interfaces. Only Global nodes containing data are presented in the generated JSON file.
Differently from the previous example, this one is using embedded Python only, no ObjectScript. Therefore PURE

Variables in Global Name

I have a number of globals I want to loop through depending on a passed in string...

^A("SYSTEM")

^B("SYSTEM")

^C("SYSTEM")

^D("SYSTEM")

^E("SYSTEM")

I am passing in a string of "A:C:D"

Piecing that to pull out A,C,D, then want to use that to pull out A,C,D from above, but having problems setting the name of the global to be the name of the variable I have pulled out of the string

How do I set this?

I have tried ^varname("SYSTEM")

Hi Community,


In this article, I will introduce Python Flask Web Framework. Together we will create a minimal web application to connect to IRIS and get data from it.

Below you can find the steps we will need to follow:

  • Step 1 : Introduction to Python Flask Web Framework
  • Step 2 : Installation of Flask module
  • Step 3 : Creation of web application using Flask
  • Step 4 : Use of HTML Templates
  • Step 5 : Installation of IRIS Python Native module
  • Step 6 : Establishment of a connection with IRIS
  • Step 7 : Transferring data from IRIS to Flask and displaying it

So Let's start with step 1

Step1-Introduction to Python Flask Web Framework

Flask is a small and lightweight Python web framework that provides useful tools and features that make creating web applications in Python easier. It gives developers flexibility and is a more accessible framework for new developers since it allows to build a web application quickly using only a single Python file. Flask is also extensible and doesn’t requires a particular directory structure or complicated boilerplate code before getting started.


For more details please view Flask Documentations

Hi everyone!

I am trying to choose the best collation for a new application that will be running on a spanish locale (Chile).

I can see there are database collations for Spanish1, Spanish2, Spanish4 and Spanish5. What is the difference between them? I can't find anything on our documentation. Should I simply choose the latest (Spanish5)?

Kind regards,

Amir Samary

Greetings,

If given a global, how can I discover information on that global? More specifically, how can I discover how many indices it contains? ie: ^G(1,2,3,4,5) How can I discover that there are 5 subscripts within the Global ^G if I did not already know.

Please advise, and thanks in advance for everyone's time.

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

Hi there have been various posts around how to clean up globals without parent data but none have gone into how you solve these issues.

Our database is approaching 600gb in size so i am looking into how to reduce this.

We use standard purge tasks.

Our cache stream class has a global size of 2463243 from running global size so it is what i would like to tackle first.

1) is there any way i can find based on my oldest message session for where most of these globals

Making a blog using Python + IRIS Globals

Since I started to use internet (late 90's), I always had a CMS (content management system) present to make easier post
any information in a blog, social media or even an enterprise page. And later years putting all my code into github I
used to document it on a markdown file. Observing how easy could be persisting data into Intersystems IRIS with the
Native API I decided to make this application and force myself to forget a little of SQL and stay open to key-value database
model.

Using ZPM for Node.js

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

If you are waiting for the Kindle Edition of Caché and MUMPS – Part II, I must apologize. I believed what others told me that once I have a book manuscript, the Kindle manuscript will be easy. Being a programmer I should have remembered: "never assume anything." The conversion to Kindle is proving a much bigger task than I thought. But don't lose heart, I am working full time on it. I have as my goal before May 1st. But, then again, you know what they say about goals. ;) - - Paul Mike Kadow
