blocksize greater than or equal to 4k will inherently cause I Os of the correct size. However, not all Oracle files are written in these blocks. The controlfile for one has a different blocksize SQL select cfbsz from x kcccf; CFBSZ. 16384 16384 Luckily this is 16k and it is always 16k so as a multiple of 4k we do not have a problem. Where we do have a problem is the online redo logs SQL select lebsz from x kccle; LEBSZ. 512 512
