RE: How to make SPFILE in sync with INIT.ORA ?

Spfile is shared and can be modified dynamically without bouncing the instances.

Eg. Alter system set db_cache_size = 800m scope = [ memory | spfile | both ] sid = *

Without spfile, you can still make this change dynamically in memory, but you would have to manually update init.ora file to reflect your change. Spfile allows you to automatically capture these dynamic changes.
