Because OER is meant to be the single source of truth throughout the entire development lifecycle, Weir and Bell made the following considerations when defining the SOA Governance Solution environment strategy:
A shared instance of the SOA Governance Server (excluding OSR) to support the development lifecycle stages: Development, Test, Preproduction, and Production.
Individual—standalone instances of OSR to match each SOA Suite environment.
A sandbox instance of the SOA Governance Server for purposes of trying patches and configuration changes.
A separate passive instance of the Governance Server for disaster recovery.
