ORA-01162: block size string in file header does not match configured block sizes

What triggered the Error:

CREATE CONTROLFILE discovered that the block size for this file is incompatible with any of the configured cache blocksizes in the INIT.ORA file.

Configure the appropriate cache for this block size using one of the various (db_2k_cache_size, db_4k_cache_size, db_8k_cache_size, db_16k_cache_size, db_32K_cache_size) parameters.
