Spoilers: Daily Integrity Checks are not only a best practice, but they also provide a snapshot of global sizes and density.

Update: Many of the below utilities now offer a mode to estimate the size with <2% error on average with orders of magnitude improvements in performance and IO requirements. I continue to urge regular Integrity Checks, however there are situations where more urgent answers are needed.

We are migrating to new servers, and I need to copy the information from Business Partner's over to the new server. Is this information in a Global or SQL table somewhere that I can export and import into the new IRIS environment?

Thanks

Those of you that worked already with ECP might know that it operates not only across
operating systems, processor technologies (big-little-endian), but also -with limits- across versions in C/E.
This cross-version feature also includes IRIS (verified for 2020.1) and C/E (2018.3)

Out of curiosity, I was looking in ^ROUTINE global to see how routines are stored internally.

I found out that lot of nodes are displaying "~pointer" as associated value (eg: instead of a string).

What are those pointers ? My guess is that it references some cache internal structure (eg: some nodes inside a B-Tree).

Is there a easily way to see what is behind ? Are pointers useful for user globals or is this something purely internal to Cache database ?

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

Hello community,

is there anything special to consider when running a foundation production regarding purge jobs (Ens.Util.Tasks.Purge)? I am thinking specifically of the QuickStreams, which according to my information are stored in a temporary database until the system is restarted. Since a system reboot is much less frequent then the purges, I wonder what happens to the QuickStreams whose messages and headers have already been purged. Is there a way to view Quickstreams (not content, but rather metadata) e.g. via the Management Portal?

Thanks for your comments and hints,

Hi, devs!

Consider you have an arbitrary global with an unknown amount of indexes.

How to print all the values to the terminal with Embedded Python?

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

I am using $Query to loop through a global.

When I use $GET to get the data all we get back is the global name.

How do you get the value of the global after you have looped.

Below is my example in terminal.

Thank you in advance

Set node = $Query(^FromExtraMed(""))

w node
^FromExtraMed("A02",9220)

If i try w $GET(node) it returns

^FromExtraMed("A02",9220)

If i had this hardcoded it would have got the value

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

My major interest is Working with Globals in Embedded Python.
So I checked the available official documentation.

Hey Developers,

We are super excited to announce the winners of the InterSystems Globals contest!

The winners of the 19th programming contest are as follows:

I would like to introduce my new project for the Globals Contest. A very new view for the globals browser

Motivation

This project was thought of when I was thinking of how to let Python code deal naturally with the scalable storage and efficient retrieving mechanism given by IRIS globals, through Embedded Python.

My initial idea was to create a kind of Python dictionary implementation using globals, but soon I realized that I should deal with object abstraction first.

So, I started creating some Python classes that could wrap Python objects, storing and retrieving their data in globals, i.e., serializing and deserializing Python objects in IRIS globals.
