Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

■ Creating and resynchronizing a database are supported by Veritas
Storage Foundation for Oracle RAC. Reverse resynchronization is
not supported.
■ The dbed_vmsnap command can only be used on the primary
host. In an Oracle RAC environment, the dbed_vmsnap command
can only be used on the Veritas Volume Manager CVM volume.
■ If possible, do not share volumes between Oracle database files
and other software.
■ When creating a snapshot volume, create the snapshot on a
separate controller and on separate disks from the primary volume.
■ Make sure your archive log destination is separate from your Oracle
database volumes.
■ Do not place any datafiles, including control files, in the
$ORACLE_HOME/dbs directory.
■ Resynchronization speed varies based on the amount of data
changed in both the primary and secondary volumes when the
mirror is broken off.
■ See the dbed_vmsnap(1M) manual page for more information.
