--------------------------------------------------------------------------------
/archlog/1_10_1185485602.dbf
/archlog/1_11_1185485602.dbf
2.目标端配置相同路径
[oracle@cmxbak ~]$ ll /archlog/
ps：若有旧数据的归档，直接删除
3.传输归档日志
[oracle@cmxdb /oracle/rmanback]$ scp /archlog/* 10.0.0.33:/archlog
oracle@10.0.0.33's password:
1_10_1185485602.dbf 100% 31MB 103.3MB/s 00:00

1_12_1185485602.dbf 100% 29MB 90.4MB/s 00:00
4.目标端查看
[oracle@cmxbak ~]$ ll /archlog/
total 569756
-rw-r----- 1 oracle oinstall 32854528 Dec 1 16:10 1_10_1185485602.dbf
-rw-r----- 1 oracle oinstall 37998080 Dec 1 16:10 1_11_1185485602.dbf
5.目标端配置环境变量
[oracle@cmxbak ~]$ cd
调整目标端的ORACLE_SID
[oracle@cmxbak ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup program
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_BASE=/oracle/dbsoft
export ORACLE_HOME=/oracle/dbsoft/product/ora11g
export ORACLE_SID=cmxdb
export ORACLE_TERM=xterm
export BASE_PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$BASE_PATH

export PATH
[oracle@cmxbak ~]$ source .bash_profile
5.恢复
5.1 恢复到nomount状态
1.查看参数文件中的路径并进行创建
[oracle@cmxbak ~]$ cat /oracle/rmanback/init31.ora

[oracle@cmxbak ~]$ mkdir -p /oradata/cmxdb/
[oracle@cmxbak ~]$ mkdir -p /oracle/dbsoft/fast_recovery_area/cmxdb/
2.使用新参数文件启动到nomount状态
startup nomount pfile='/oracle/rmanback/init31.ora';
show parameter instance_name --复核实例名配置是否正常
create spfile from pfile='/oracle/rmanback/init31.ora';
shutdown immediate;
startup nomount;
show parameter ARCH
show parameter fal_server
show parameter fal_client
show parameter standby_file_management
show parameter name
3.检查启动的实例
[oracle@cmxbak ~]$ ps -ef |grep pmon
oracle 23399 1 0 16:16 ? 00:00:00 ora_pmon_cmxdb
oracle 23440 23065 0 16:17 pts/0 00:00:00 grep --color=auto pmon
5.2 恢复到mount状态
1.恢复控制文件
方式一：使用rman恢复指定控制文件
[oracle@cmxbak /oracle/rmanback]$ rman target /
Recovery Manager: Release 11.2.0.4.0 - Production on Sun Dec 1 16:19:54 2024
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: CMXDB (not mounted)
RMAN> restore controlfile from '/oracle/rmanback/control_01.dbf';
Starting restore at 2024-12-01 16:20:03
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=572 device type=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output file name=/oradata/cmxdb/control01.ctl
output file name=/oracle/dbsoft/fast_recovery_area/cmxdb/control02.ctl
Finished restore at 2024-12-01 16:20:04
方式二：查看参数文件中控制文件的位置，将控制文件cp到指定的位置
此种方法需要手动生成的控制文件，并非备份的控制文件
[oracle@cmxbak /oracle/rmanback]$ cat init31.ora |grep control_files
*.control_files='/oradata/cmxdb/control01.ctl','/oracle/dbsoft/fast_recovery_area/cmxdb/control02.ctl'
[oracle@cmxbak /oracle/rmanback]$ cp /oracle/rmanback/control01.ctl /oradata/cmxdb/control01.ctl
[oracle@cmxbak /oracle/rmanback]$ cp /oracle/rmanback/control01.ctl /oracle/dbsoft/fast_recovery_area/cmxdb/control02.ctl
[oracle@cmxbak /oracle/rmanback]$ ll /oradata/cmxdb/control01.ctl
-rw-r----- 1 oracle oinstall 9895936 Dec 5 17:00 /oradata/cmxdb/control01.ctl
[oracle@cmxbak /oracle/rmanback]$ ll /oracle/dbsoft/fast_recovery_area/cmxdb/control02.ctl
-rw-r----- 1 oracle oinstall 9895936 Dec 5 17:00 /oracle/dbsoft/fast_recovery_area/cmxdb/control02.ctl
2.启动到mount状态
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
3.数据库中查看数据库的状态
SQL> select OPEN_MODE,database_role from v$database;
