native-api-global-view-and-copy

A utility using IRIS NativeAPI to View, Copy, and Merge Globals
This code runs rather slowly and creates a lot of network traffic.
!! There is no need for any additional code on the source server !!

Background:
As $QUERY is not supported by Native API it is a rather long and
boring workaround with the functions IsDefined (aka $DATA) and
GetNext (aka $ORDER) to examine all Global nodes with value
and passing the structural nodes.

You have to provide
- your credentials for server access
- your level of error handling

First, you make a connection to the target SuperServer Port

do ##class(nacl.Client).Connect("192.168.0.99",41773)
- VIEW and COPY are the same code
- VIEW is simply a COPY to NUL device
- The target in COPY can have a different name
- Using a local variable as target mimics the MERGE command
- Start and Stop Subscript allow partial operation
- Stop Subscript is the first to be excluded.

 
Do ##class(nacl.GVC).Connect(serverIP,serverPORT,namespace,username,password)    
Do ##class(nacl.GVC).View(globalname,startsubscript,stopstcsript)    
Do ##class(nacl.GVC).Copy(globalname,startsubscript,stopstcsript,targetname)    

Copy writes a View of the created output.

Prerequisites

Make sure you have git and Docker desktop installed.

On your target server, you need to install
https://github.com/rcemper/native-api-command-line-extension

Installation

Clone/git pull the repo into any local directory

git https://github.com/rcemper/native-api-command-line-client

Run the IRIS container with your project:
