22.2.4 and higher Modelling Gateway import failed with certain landscape handles

Products

• CA Spectrum

Issue/Introduction

We use the modelling gateway for export and import devices and containers from one landscape to another.
 
The import fails when the source landscape_handle is "0x1a00000".
But the import is successful when the source  landscape_handle is "0xb00000"
 
This source landscape is the main difference between Export_0x1a.xml and Export_0xb.xml.
The containers and devices are the same.
 
We do not understand why "0x1a00000" is failing while "0xb00000" is working, as both are legacy landscape handles.

Environment

Release : 22.2.4 and higher

 

Spectrum Modeling Gateway

Cause

Changes were made to the Modeling Gateway in 22.2.4+ to support huge landscape handle

Resolution

If you are using legacy landscape handles you need to make sure the following setting in the .modelinggatewayexport.xml file is set

 

huge_landscape_import = "false"

 

The default setting is true

 

The reason why it was working for some landscape handles such as 0xb00000 is that those landscape handles do not have any overlap.
