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

In the versions specified above, an instance may fail to start or may hang during operation if the database cache is greater than or equal to 2,097,152 MB (2 TB).
I’m trying to find a way to manage globals from our Java application. We have two separate features:
Managing tables normally using SQL
Managing globals, since some globals exist without class or table definitions
Cache version : Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.1.1 (Build 108U_SU), Thu Jul 7 2016 09:39:04 EDT
I tried to retrieve the globals tree, update node values, and append nodes using SQL by calling stored procedures, but I couldn’t find any procedures for adding, updating, or deleting nodes.
I also tried using cacheextreme.jar to access the globals API directly.
1 Introduction
In environments that use InterSystems IRIS, globals are the physical foundation of data storage. Although system queries and administrative tools exist for metric inspection, global growth analysis is usually reactive: the problem is generally only noticed when there is disk pressure or performance impact.
