1、还原数据库
db2 restore db dc from /db2_backup/dc taken at 20121102142900 with 1 buffers buffer 256
2、回滚数据库，1>和2>只执行其一。
1>、作用是将数据库回滚到最新日志时间
db2 rollforward db dc to end of logs and stop
2>、作用将数据库回滚到指定时间
db2 rollforward db dc to 2012-11-08-14.05.27 using local time
3、完成数据库回滚
db2 rollforward db dc stop
4、下面是一个还原数据库并进行回滚的一个例子。
