Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

■ When the Quick I/O feature is available, Oracle Disk Manager uses

the Quick I/O driver to perform asynchronous I/O. Do not turn off

the Quick I/O mount option, which is the default.

■ Oracle uses default file access methods if Oracle10g or later or a

Veritas Storage Foundation Standard or Enterprise product is not

installed, or VxFS 5.0 or later is not available in the kernel.
