Well there are whole lot of changes when you start comparing Oracle 10g and 11g.  DB_ULTRA_SAFE is one of the new parameter introduced in 11g which provides a mechanism to avoid block corruptions in your database. his parameter actually controls three parameters DB_BLOCK_CHECKING, DB_BLOCK_CHECKSUM & DB_LOST_WRITE_PROTECT parameters collectively.
Click on below provided links in order to read more about these three three initialization parameters.

      Hello Oracleman,
      Both DB_BLOCK_CHECKING and DB_BLOCK_CHECKSUM were available in 10g r2 as well except tha last DB_LOST_WRITE_PROTECT which was introduced in 11g r1.
      so they are available in 11g r2 as well without any change.

      Thanks for your time to read and comment.
