Oracle (RAC) Database Consolidation Guidelines for Environments Using Mixed Database Versions (Doc ID 1439551.1)

Last updated on AUGUST 05, 2021

Applies to:

Oracle Database Cloud Exadata Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
Oracle Database Cloud Service - Version N/A and later
Oracle Database - Enterprise Edition - Version to [Release 10.1 to 11.2]
Information in this document applies to any platform.


The purpose of this document is to point out some of the differences that exist between Oracle Real Application Clusters (RAC) 11g Release 2 and earlier versions which need to be taken into account when multiple databases are to be consolidated on the same system.


Oracle can only give guidance rather than "rules" as there are many variables to consider and each customer will need to use this guidance within the context of their particular environments knowing better about their application requirements, SLAs, hardware capabilities, resource consumption and workloads. Please review Best Practices for Database Consolidation in Private Clouds for discussion of which factors should be considered. For general considerations regarding running pre-11g Release 2 Oracle RAC databases in 11g Release Oracle Grid Infrastructure environments, see My Oracle Support note 948456.1.
