This document outlines the infrastructure and maintenance process for a CZ Gold Configurator system connected to Oracle EBS instances. It describes how the GoldCZ instance is used for model development and should not be refreshed from other instances. It also describes how the bill of materials (BOM) source is the Oracle Production EBS instance and how BOM/UDA data is published from GoldCZ to EBS instances for testing. Periodic purging of configurator tables is recommended in GoldCZ and Production EBS to clean up orphan records.
