Instant File Initialisation on Windows Oracle Server I require to add additional datafiles to a SmallFile tablespace. The process took several minutes on my system for 1 datafile.

Is it possible to allow Oracle the same capability as SQL Server using instant file initialisation? my googling was unproductive.

Thanks,

Chris
No, Oracle does not take advantage of that security policy and always zeroes out the files before writing to them. 

I have no idea whether ASM behaves in a different way, but in the filesystem files are always initialized.
