Re: DB_BLOCK_SIZE --- How ??

First of all, IMO there are only very rare cases where 16k is advantegeous. I just returned from a customer where I saw the detrimental consequences: many tables are smaller than db_file_multiblock_read_count * db_block_size, so whatever index: they will be read using full table scan. Secondly, you can't change this parameter, the init<sid>.ora needs to have the correct value *PRIOR* to database creation. As you don't specify which version you are using, I can't tell you whether the oradim utility, the installer or the database assistant will allow you to change it on the fly, some do, some don't
