本文模拟了Oracle的重定向恢复
上一篇文章讲了Oracle本机的备份与恢复 本文主要讲了Oracle重定向恢复的过程。将原来的数据库删除之后，改变了备份片的存储位置，然后恢复数据文件到一个不同的目录原始备份片位置：/home/oracle/orcbackup 原始数据文件路径：/home/oracle/app/oracle/oradata/orcl/ 把备份片移动到 /home/oracle/ newbackup下 目标是把数据文件路径恢复到/home/oracle/ newfilepath/orcl下 1. 删除数据库SQL> shutdown immediate;SQL> startup force mount; SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION; SQL> drop database; 2.移动备份片创建备份片新的目录，并移动备份片，里面包括了spfile/control file、数据文件、归档日志的备份：[oracle@node01 ~]$ mkdir -p /home/oracle/newbackup [oracle@node01 ~]$ mv /home/oracle/orcbackup/* /home/oracle/newbackup/ [oracle@node01 ~]$ ls -l /home/oracle/newbackup/ total 2379324 -rw-r-----. 1 oracle oinstall 1091559424 Mar 9 21:25 rman1_0pstcmht_1_1.bk -rw-r-----. 1 oracle oinstall 549445632 Mar 9 21:26 rman1_0qstcmjb_1_1.bk -rw-r-----. 1 oracle oinstall 537649152 Mar 9 21:26 rman1_0rstcmk5_1_1.bk -rw-r-----. 1 oracle oinstall 201296384 Mar 9 21:29 rman1_0tstcmp1_1_1.bk -rw-r-----. 1 oracle oinstall 18825216 Mar 9 21:26 rman_ctl_c-1496578512-20180309-01.bk -rw-r-----. 1 oracle oinstall 18825216 Mar 9 21:29 rman_ctl_c-1496578512-20180309-02.bk -rw-r-----. 1 oracle oinstall 18825216 Mar 9 22:04 rman_ctl_c-1496578512-20180309-03.bk 3. 创建数据文件目录[oracle@node01 ~]$ mkdir -p /home/oracle/newfilepath/orcl4. 恢复spfile[oracle@node01 ~]$ export ORACLE_SID=orcl[oracle@node01 ~]$ echo "db_name=orcl" > $ORACLE_HOME/dbs/pfile_tmp.ora RMAN> startup nomount pfile='$ORACLE_HOME/dbs/pfile_tmp.ora'; RMAN> restore spfile from '/home/oracle/newbackup/rman_ctl_c-1496578512-20180309-02.bk'; RMAN> shutdown immediate; RMAN> startup nomount; 5. 恢复控制文件由于备份片位置发生了变化，所以要用catalog start with 指定新的位置RMAN> restore controlfile from '/home/oracle/newbackup/rman_ctl_c-1496578512-20180309-03.bk'; RMAN> alter database mount; RMAN> catalog start with '/home/oracle/newbackup/'; searching for all files that match the pattern /home/oracle/newbackup/ List of Files Unknown to the Database ===================================== File Name: /home/oracle/newbackup/rman1_0pstcmht_1_1.bk File Name: /home/oracle/newbackup/rman1_0qstcmjb_1_1.bk File Name: /home/oracle/newbackup/rman1_0rstcmk5_1_1.bk File Name: /home/oracle/newbackup/rman1_0tstcmp1_1_1.bk File Name: /home/oracle/newbackup/rman_ctl_c-1496578512-20180309-01.bk File Name: /home/oracle/newbackup/rman_ctl_c-1496578512-20180309-02.bk File Name: /home/oracle/newbackup/rman_ctl_c-1496578512-20180309-03.bk Do you really want to catalog the above files (enter YES or NO)?
