SF Oracle RAC does not support the following:

• Dissimilar version upgrades of SF Oracle RAC components

  For example, if you have SF Oracle RAC 4.1 installed with Oracle RAC 9i Release 2, you can not upgrade only VCS to version 5.1 Service Pack 1.

• Option hawizard -rac for configuring service groups

• 32-bit Oracle architectures

• Oracle RAC 9i, Oracle RAC 10g Release 1

• ASMInst agent

  The ASMInst agent is no longer supported in SF Oracle RAC environments. The ASM instances are managed by Oracle Clusterware.

• Use of crossover cables

  Oracle does not support the use of crossover cables for cluster interconnects due to the possibility of data corruption and other software limitations.

  Note:

  Crossover cables are however known to function without any issues in SF Oracle RAC. While the SF Oracle RAC Technical support team may continue to provide support on related issues for existing deployments, this support may be constrained in some respects as it is no longer a supported configuration by Oracle. The use of crossover cables is discouraged for new deployments.

• Bunker replication is not supported in a Cluster Volume Manager (CVM) environment.
