Oracle RAC Resource Runtime Management allows for automatic and runtime adjustment of the SGA.

Oracle RAC Resource Management only allows assignment of the SGA during database startup.

If ASM disk groups are configured for the Clusterware files, then ASM must be used for all databases on the cluster.

The Installer permits the creation of a disk group to be used for the Recovery Area for the ASM instance.

If no ASM disk groups are specified during installation, then ASM instances are not started after the installation completes on any cluster node.

Different nodes in a cluster may belong to separate administrator-defined categories.

All nodes in a cluster belong to the same Oracle-supplied category.

A server may be added to only one category using the crsctl utility.

All server attributes that may be used to determine the server category are discovered automatically by Oracle Clusterware.

A copy of an encrypted file is not encrypted unless it is created in an encrypted directory.

An ACFS snapshot can be ACFS encrypted.

acfsutil encr off can be run by an encryption manager who may not have system administrator privileges.
