Accessing regular VxFS files as Quick I/O files
You can access regular VxFS files as Quick I/O files using the ::cdev:vxfs: name
extension.
While symbolic links are recommended because they provide easy file system
management and location transparency of database files, the drawback of using
symbolic links is that you must manage two sets of files (for instance, during
database backup and restore).
■ When possible, use relative path names instead of absolute path
names when creating symbolic links to access regular files as Quick
I/O files. Using relative path names prevents copies of the symbolic
link from referring to the original file when the directory is copied.
This is important if you are backing up or moving database files
with a command that preserves the symbolic link.
However, some applications require absolute path names. If a file
is then relocated to another directory, you must change the
symbolic link to use the new absolute path. Alternatively, you can
put all the symbolic links in a directory separate from the data
directories. For example, you can create a directory named
/database and put all the symbolic links there, with the symbolic
links pointing to absolute path names.
