The qio_recreate command automatically recreates Quick I/O files after the database is recovered. The command expects to find a file named mkqio.dat in the directory where the qio_recreate command is run. The mkqio.dat file contains a list of the Quick I/O files used by the database and their sizes. If the mkqio.dat file is not in the directory, you will be prompted to create it using qio_getdbfiles. After creating mkqio.dat, you will be able to run the qio_recreate command successfully. No output is returned when the command runs successfully.

The qio_recreate command supports conventional Quick I/O files only (that is, Quick I/O files in the following form: file --> .file::cdev:vxfs:). In creating a Quick I/O file, the qio_recreate command renames the regular VxFS file, file, to .file with the Quick I/O extension (::cdev:vxfs:) and creates a symbolic link to it. By default, the symbolic link uses a relative path name.

The command is available in the /opt/VRTSdbed/bin directory.

The following option is supported:

-T database_type	Specifies the database type as ora for Oracle.

You must be logged in as the instance owner to run this command. You must first recover the database before running qio_recreate.

To use this command for Oracle, the ORACLE_SID environment variable must be set.

The qio_recreate command follows these rules in recreating Quick I/O files when a database is recovered:

o	If a Quick I/O file (.file) is missing, then qio_recreate recreates it.
o	If both a symbolic link (file) and its associated Quick I/O file (.file::cdev:vxfs:) are missing, then qio_recreate recreates both the symbolic link and the Quick I/O file.
o	If a symbolic link (file) from a regular VxFS file to its associated Quick I/O file (.file::cdev:vxfs:) is missing, then qio_recreate recreates the symbolic link.
o	If a Quick I/O file (.file::cdev:vxfs:) is missing and the regular VxFS file that is symbolically linked to it is not the same one that originally created it, then qio_recreate issues a warning message and does not recreate the Quick I/O file.
o	If a Quick I/O file (.file::cdev:vxfs:) is smaller than the size listed in mkqio.dat, qio_recreate issues a warning message and does not recreate the Quick I/O file.
