Hi Johnson,
I don't believe that tempfiles can be sparse (although I may be wrong) and I am
confident that datafiles cannot be. Maybe you should log a TAR with Oracle
support to checkout whether tempfile can be sparse and just use datafiles until
then. Anyway, can you please post the URL to the tip you mentioned. While it is
the sort of thing I might say, I don't remember actually having said so.

Hi,
After reading Steve Adams' tip on making temp files
quick io. I posed this question to Veritas as they had
told us not do so. The answer they give is the
following.
Temporary datafiles should not be converted to quick
i/o files. The following is an excerpt from the
administrator's Guide: Tablespaces marked TEMPORARY
can be sparse, which means that not all blocks in the
file are allocated. Quick I/O files cannot be sparse,
as Quick I/O provides a raw-type interface to storage.
If a sparse file is converted to a Quick I/O file, the
Oracle instance can fail if Oracle attempts to write
into one of these unallocated blocks.
I would appreciate your thoughts on this?
Johnson Job
