Small Rowid using bigfile tablespace

Filed under: Uncategorized — Helio Dias @ 4:42 pm

Since the bigfile comprise just one file , isn´t necessary to store relative file number on rowid, so Oracle cut it 3 bytes from rowid.

I´ll investigate, but i guess it will improve performance (less space=>less memory=>more performance)

  1. Definitely research…because the rowid still has the bytes, they are just put to better use.
