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?
