About backing up and restoring Quick I/O files using

Oracle RMAN

Quick I/O files are treated as raw devices by Oracle Recovery Manager (RMAN)

and must be backed up and restored the same way as raw devices. A Quick I/O file

consists of two components: a regular file with space allocated to it and a link

pointing to the Quick I/O interface for the file.

When a Quick I/O file is created with the qiomkfile command, the regular file

with the preallocated space is a hidden file. For example, dbfile points to

.dbfile::cdev:vxfs: and .dbfile is the hidden file with the space allocated.

(These names are used in the examples throughout this section.)

For backup, RMAN reads the Oracle datafile using the Quick I/O interface, but

does not process or store the special link between the hidden file with the allocated

space (.dbfile) and the link to its Quick I/O interface (dbfile, which points to

.dbfile::cdev:vxfs:). This has implications for the restore operation, as

described in the rest of this section.
