  standby database storage area signature does not match master
  database

  Explanation:  The number of storage area slots ("reserved"), or
  the specific storage area page size, are not identical on both
  the master and standby databases.

  User Action:  Make sure both the master and standby database
  storage area configurations are identical.  Do not change any
  storage area page size when restoring the databases.
