db2数据库还原命令   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;    www.2cto.com   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;    如需帮助,请发邮件到 lyc557@163.com
