ORA-03206: maximum file size of XXXX blocks in AUTOEXTEND clause is out of range

If you are creating SMALLFILE datafile (default) with 8k blocks with datafile size greater than 32 GB than oracle will pop up with ORA-03206 error.

Because oracle will allow only up to 32 GB of datafile size limit with 8k blocks, maximum data blocks per datafile : 2^22 -1 = 4194303. So oracle simply won’t allow you in this case.

More than 32 GB datafile with 8k blocks than your datafile should be create with BIGFILE keyword.
Calculations are as follows:
Oracle allows max number of datafile is 65533 and Maximum data blocks per datafile is 2^22 -1 = 4194303 blocks.
