Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

Extends a file by a specified amount to allow Oracle tablespace resizing.

See “Extending a Quick I/O file” on page 94.

-e

Specifies the Oracle datafile header size. This option specifies a header

that will be allocated in addition to the size specified because Oracle

requires one additional database block for all its datafiles. If this option

is used, the resulting file can be used as an Oracle datafile. When

creating an Oracle datafile, the header size should be equal to the

Oracle block size (as determined by the DB_BLOCK_SIZE parameter).

If the header size is missing when the -h option is used, a 32K header

will be allocated.

-h

Increases the file to a specified size to allow Oracle tablespace resizing.

See “Extending a Quick I/O file” on page 94.

-r

Specifies the space to preallocate for a file in bytes, kilobytes,

megabytes, gigabytes, or sectors (1024 bytes) by adding a k, K, m, M, g,

G, s, or S suffix. The default is bytes—you do not need to attach a suffix

to specify the value in bytes. The size of the file that is preallocated

is the total size of the file (including the header) rounded to the nearest

multiple of the file system block size.

-s

Warning: Exercise caution when using absolute path names. Extra steps may be

required during database backup and restore procedures to preserve symbolic

links. If you restore files to directories different from the original paths, you must

change the symbolic links that use absolute path names to point to the new path

names before the database is restarted.
