Yes. The Oracle Clusterware should always run at the highest level. With Oracle Clusterware 11g, you can run both Oracle RAC 10g and Oracle RAC 11g databases. If you are using ASM for storage, you can use either Oracle Database 10g ASM or Oracle Database 11g ASM however to get the 11g features, you must be running Oracle Database 11g ASM. It is recommended to use Oracle Database 11g ASM. Note: When you upgrade to 11g Release 2, you must upgrade both Oracle Clusterware and Automatic Storage Management to 11g Release 2. This will support Oracle Database 10g and Oracle Database 11g (both RAC and single instance). Yes, you can run Oracle 9i RAC in the cluster as well. 9i RAC requires the clusterware that is certified with Oracle 9i RAC to be running in addition to Oracle Clusterware 11g.
