To add to what Niall said, I think you can only change it during the database creation. If you have a database already running, you would be well off letting it go.

Someone here also said you may come across lot of bugs where running with anything other than 8K. In another word, the performance gain is not worth it as the change will trigger way too many problems

2^22 * (block_size) so 64 and 128gb respectively. This obviously assumes that

  1. you are using smallfile tablespaces and
  2. the os doesn't impose a lower limit.

There's a section in the docs for your version called database limits that contains this and other useful info.

Does anyone know for 16K and 32K what is max file size?

Does max file size different on X86 and X86_64 version?
