一、备份数据库
[db2inst2@localhost ~]$ db2 backup db ghan to /db2inst2/
备份成功。此备份映像的时间戳记是:20151102072618
二、生成数据库定向还原脚本
[db2inst2@localhost ~]$ db2 restore db ghan from /db2inst2/ taken at 20151102072618 redirect generate script redirect123.ddl
DB20000I RESTORE DATABASE 命令成功完成。
三、自定义还原数据库及容器目录
[db2inst2@localhost ~]$vi redirect123.ddl //修改用户名及容器路径
1、修改:inot 重定向用户名:
2、修改:TABLESPACE CONTAINERS 路径
3、注意 自动存储管理不能重定向、且 RESTORE DATABASE 原数据库名 CONTINUE。
四、执行自定还原脚本
[db2inst2@localhost ~]$ db2 -tvsf redirect123.ddl
UPDATE COMMAND OPTIONS USING S ON Z ON GHAN_NODE0000.out V ON
DB20000I UPDATE COMMAND OPTIONS 命令成功完成。
SET CLIENT ATTACH_DBPARTITIONNUM 0
DB20000I SET CLIENT 命令成功完成。
SET CLIENT CONNECT_DBPARTITIONNUM 0
DB20000I SET CLIENT 命令成功完成。
RESTORE DATABASE GHAN FROM '/db2inst2/' TAKEN AT 20151102072618 INTO TANK123 REDIRECT
SQL2529W 警告!复原到与备份映像数据库不同的现有数据库中
,现有数据库的别名 "TANK123" 与备份映像的别名 "GHAN"
不匹配,现有数据库的数据库名称 "TANK123"
与备份映像的数据库名称 "GHAN"
不匹配。目标数据库将被备份版本覆盖。将删除与目标数据库
相关联的前滚恢复日志。
想要继续吗?(y/n) y
SQL1277W 正在执行重定向复原操作。现在,可以查看表空间配
置,并且不使用自动存储器的表空间可以重新配置它们的容器
。
DB20000I RESTORE DATABASE 命令成功完成。
SET TABLESPACE CONTAINERS FOR 4 USING ( FILE '/db2inst2/data_tb/cont0_123' 6400 , FILE '/db2inst2/data_tb/cont1_123' 19200 )
DB20000I SET TABLESPACE CONTAINERS 命令成功完成。
SET TABLESPACE CONTAINERS FOR 5 USING ( PATH '/db2inst2/data_tb/tab_temp_123' )
DB20000I SET TABLESPACE CONTAINERS 命令成功完成。
SET TABLESPACE CONTAINERS FOR 6 USING ( PATH '/db2inst2/data_tb/tab_usertemp_123' )
DB20000I SET TABLESPACE CONTAINERS 命令成功完成。
db2 "RESTORE DATABASE GHAN CONTINUE"
DB20000I RESTORE DATABASE 命令成功完成。。
五、前滚数据库
[db2inst2@localhost ~]$ db2 rollforward db tank123 to end of logs and stop
前滚状态
输入数据库别名 = tank123
节点数已返回状态 = 1
节点号 = 0
前滚状态 = 未暂挂
下一个要读取的日志文件 =
已处理的日志文件 = -
上次落实的事务 = 2015-11-01-23.29.36.000000 UTC
DB20000I ROLLFORWARD 命令成功完成。
六、查看还原结果
[db2inst2@localhost ~]$ db2 "select count(*) from empl"
1
-----------
4660010
1 条记录已选择。
七、查看目录数据库表空间信息
[db2inst2@localhost ~]$ db2pd -d tank123 -tablespace
Database Partition 0 -- Database TANK123 -- Active -- Up 0 days 00:02:51 -- Date 11/02/2015 08:42:20
