1.备份的数据库(olddb) 与要还原的数据(newdb)名不相同:

db2 restore db olddb into newdb;

www.2cto.com

2.当前目录下存在多个备份文件.需要指定时间

db2 restore db olddb taken at 20120819175932 into newdb;

3.需要指定备份文件的目录

db2 RESTORE DATABASE olddb FROM "/media/olddb.0.db2inst1.NODE0000.CATN0000.20120819175932.001"

TAKEN AT 20120819175932 INTO newdb;

4.需要指定newdb NEWLOGPATH路径

db2 RESTORE DATABASE olddb FROM "/media/olddb.0.db2inst1.NODE0000.CATN0000.20120819175932.001"

TAKEN AT 20120819175932 NEWLOGPATH "/opt/log" WITH 2 BUFFERS BUFFER 1024 INTO newdb;

5.需要指定表空间的

1).创建文件夹

mkdir /home/db2inst1/db2space/newdb_sp0;

mkdir /home/db2inst1/db2space/newdb_sp1;

mkdir /home/db2inst1/db2space/newdb_sp2;

mkdir /home/db2inst1/db2space/newdb_sp3;

mkdir /home/db2inst1/db2space/newdb_sp4;

mkdir /home/db2inst1/db2space/newdb_sp5;

mkdir /home/db2inst1/db2space/newdb_sp6;

2).还原命令加入 redirect without rolling forward

db2 RESTORE DATABASE olddb FROM "/media/olddb.0.db2inst1.NODE0000.CATN0000.20120819175932.001"

TAKEN AT 20120819175932 NEWLOGPATH "/opt/log" WITH 2 BUFFERS BUFFER 1024 INTO newdb

redirect without rolling forward;

3).设置表空间目录

SET TABLESPACE CONTAINERS FOR 0 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp0");

SET TABLESPACE CONTAINERS FOR 1 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp1");

SET TABLESPACE CONTAINERS FOR 2 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp2");

SET TABLESPACE CONTAINERS FOR 3 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp3");

SET TABLESPACE CONTAINERS FOR 4 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp4");

SET TABLESPACE CONTAINERS FOR 5 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp5");

SET TABLESPACE CONTAINERS FOR 6 IGNORE ROLLFORWARD CONTAINER OPERATIONS USING (PATH "/home/db2inst1/db2space/newdb_sp6");

3).还原继续.注意为olddb

RESTORE DATABASE olddb CONTINUE;

6.数据库还原退回

db2 restore db 注意为olddb abort

7.还原后如果NEWLOGPATH 需要变更的

db2 UPDATE DB CFG FOR newdb USING NEWLOGPATH /db2/db2inst1/db2logpath

db2 UPDATE DB CFG FOR newdb USING LOGFILSIZ 10001

db2 force applications all;

db2stop;

db2start;
