To measure the performance impact of arrays, a 900gb database was used and an OLTP (Online Transactional Processing) workload was exercised.
记住，完全数据库恢复将要求整个恢复操作具有排它性，而表空间的联机恢复将只要求表空间处于排它模式中。
Remember, a full database restore will require exclusive use for the entire restore operation, whereas online restore of a table space will only require that tablespace to be in exclusive mode.
