使用rman的level0的备份文件迁移oracle数据库-不完全恢复-20160811

将oracle数据库从一台机器A迁移到另外的一台机器B（同为linux平台），设置为不同的路径，不同的实例名

 

 

源端：

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=/u01/app/oracle/product/12.1.0.2/db_1

ORACLE_SID=SCPDB

数据文件位置：/u01/app/oracle/oradata/SCPDB/datafile/

 

 

目标端：

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=/u01/app/oracle/product/12.1.0.2/db_1

ORALCE_SID=SCPDB01

数据文件位置：/u01/app/oracle/oradata/SCPDB01/datafile/

 

 

把备份上传到目标端/u01/rmanSCPDB/

备份集信息：

[[email protected] /]$ ll /u01/rmanSCPDB/*

-rw-r--r--. 1 oracle oinstall 10256384 Aug 10 18:18 /u01/rmanSCPDB/ctl_auto_c-2612507248-20160712-00.bk

-rw-r--r--. 1 oracle oinstall 1089299968 Aug 10 18:18 /u01/rmanSCPDB/o12c_full_level0_SCPDB201607122erahka5_1_1.bk

-rw-r--r--. 1 oracle oinstall 2024849408 Aug 10 18:19 /u01/rmanSCPDB/o12c_full_level0_SCPDB201607122frahkan_1_1.bk

-rw-r--r--. 1 oracle oinstall 12288 Aug 10 18:19 /u01/rmanSCPDB/o12c_full_level0_SCPDB201607122grahkbg_1_1.bk

 

 

 

以下都在目标端使用oracle用户操作

 

cd $ORACLE_BASE

mkdir flash_recovery_area

mkdir -p admin/SCPDB01

cd admin/SCPDB01

mkdir {a,b,c,d,u}dump

 

 

 

 

 

开始恢复，此时恢复的实例名为SCPDB

export ORACLE_SID=SCPDB

rman target /

===================================================

==在rman启动数据库到nomount,                    ===

==还原spfile，使用nomount打开数据库                ===

==编辑一个最简单的pfile，只有db_name即可：        ===

==vi initSCPDB.ora                                    ===

==cat initSCPDB.ora                                ===

==db_name=SCPDB                                ===

==                                                ===

==也可以不用创建pfile，直接启动到nomount        ===

===================================================

RMAN> startup nomount

 

RMAN> restore spfile from ‘/u01/rmanSCPDB/ctl_auto_c-2612507248-20160712-00.bk‘;

RMAN> shutdown immediate

 

编辑参数文件，使参数中的相关路径变更为新路径

注意：ORACLE_SID=SCPDB

sqlplus / as sysdba

create pfile from spfile;

 

编辑生成的$ORACLE_HOME/dbs/initSCPDB.ora文件，

根据需要修改相应的参数，如增加sga大小等

其次修改pfile文件中的相关路径使之指向新的位置，即参数文件中所有含SCPDB目录的应修改为SCPDB01

*.audit_file_dest=‘/u01/app/oracle/admin/SCPDB01/adump‘

*.control_files=‘/u01/app/oracle/oradata/SCPDB01/controlfile/o1_mf_clozc9vs_.ctl‘,‘/u01/app/oracle/fast_recovery_area/SCPDB01/controlfile/o1_mf_clozcb1k_.ctl‘

*.log_archive_dest_1=‘location=/u01/archscp01‘

注意db_name参数不变，为原来的db_name,

待恢复完成后使用nid修改

使用pfile文件启动到nomount状态

 

 

目标端的一些参数

*.__db_cache_size=1808M

*.__java_pool_size=16M

---还原控制文件

 

export ORACLE_SID=SCPDB

 

rman target /

RMAN> startup nomount

RMAN> restore controlfile from ‘/u01/backup/ctl_auto_c-2612507248-20160809-00.bk‘;

---切换到mount状态，注，db_name务必保持原db_name，否则切换到mount时提示

---ORA-01103: database name ‘SCPDB‘ in control file is not ‘SCPDB01‘

 

RMAN> alter database mount;

RMAN> exit

 

 

 

---开启第二个窗口，修改日志文件位置

export ORACLE_SID=SCPDB

sqlplus / as sysdba

SQL> select ‘alter database rename file ‘‘‘||member||‘‘‘ to ‘‘‘||replace(member,‘SCPDB‘,‘SCPDB01‘)||‘‘‘;‘ from v$logfile;

 

 

alter database rename file ‘/u01/app/oracle/fast_recovery_area/SCPDB/onlinelog/redo08a.log‘ to ‘/u01/app/oracle/fast_recovery_area/SCPDB01/onlinelog/redo08a.log‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/onlinelog/redo08b.log‘ to ‘/u01/app/oracle/oradata/SCPDB01/onlinelog/redo08b.log‘;

alter database rename file ‘/u01/app/oracle/fast_recovery_area/SCPDB/onlinelog/redo09a.log‘ to ‘/u01/app/oracle/fast_recovery_area/SCPDB01/onlinelog/redo09a.log‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/onlinelog/redo09b.log‘ to ‘/u01/app/oracle/oradata/SCPDB01/onlinelog/redo09b.log‘;

alter database rename file ‘/u01/app/oracle/fast_recovery_area/SCPDB/onlinelog/redo05a.log‘ to ‘/u01/app/oracle/fast_recovery_area/SCPDB01/onlinelog/redo05a.log‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/onlinelog/redo05b.log‘ to ‘/u01/app/oracle/oradata/SCPDB01/onlinelog/redo05b.log‘;

alter database rename file ‘/u01/app/oracle/fast_recovery_area/SCPDB/onlinelog/redo06a.log‘ to ‘/u01/app/oracle/fast_recovery_area/SCPDB01/onlinelog/redo06a.log‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/onlinelog/redo06b.log‘ to ‘/u01/app/oracle/oradata/SCPDB01/onlinelog/redo06b.log‘;

alter database rename file ‘/u01/app/oracle/fast_recovery_area/SCPDB/onlinelog/redo07a.log‘ to ‘/u01/app/oracle/fast_recovery_area/SCPDB01/onlinelog/redo07a.log‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/onlinelog/redo07b.log‘ to ‘/u01/app/oracle/oradata/SCPDB01/onlinelog/redo07b.log‘;

 

---执行上述语句

SQL> alter database rename file ‘/u01/app/oracle/oradata/SCPDB/datafile/o1_mf_temp_cto6lh07_.tmp‘ to ‘/u01/app/oracle/oradata/SCPDB01/datafile/o1_mf_temp_cto6lh07_.tmp‘;

.......

 

 

---回到第一个窗口中

export ORACLE_SID=SCPDB

rman target /

 

---使用catalog start with指定备份文件位置

RMAN> catalog start with ‘/u01/backup/‘;

 

---还原及恢复数据库，由于使用了不同的位置，因此我们需要使用set newname 子句，如下面的示例

run{

allocate channel ch1 device type disk;

set newname for datafile 1 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/system.dbf‘;

set newname for datafile 3 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/sysaux.dbf‘;

set newname for datafile 4 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/undotbs1.dbf‘;

set newname for datafile 6 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/users.dbf‘;

set newname for datafile 2 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/TBS_NotifyDB.dbf‘;

set newname for datafile 5 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/TBS_gmscp.dbf‘;

set newname for datafile 7 to ‘/u01/app/oracle/oradata/SCPDB01/datafile/tbsp_index01.dbf‘;

restore database;

release channel ch1;

switch datafile all;

}

=====================================================================================

----也可以使用

set newname for database to ‘/u01/app/oracle/oradata/SCPDB01/datafile/%b‘;

run{

allocate channel ch1 device type disk;

set newname for database to ‘/u01/app/oracle/oradata/SCPDB01/datafile/%b‘;

restore database;

release channel ch1;

switch datafile all;

}

=====================================================================================

 

 

 

 

 

RMAN> recover database;

 

---Recover过程中会收到如下错误提示

 

archived log thread=1 sequence=614

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of recover command at 08/11/2016 14:21:27

RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 614 and starting SCN of 8223302

 

 

RMAN> recover database until sequence 614;

 

RMAN> alter database open resetlogs;

 

 

---修改临时文件位置

export ORACLE_SID=SCPDB

sqlplus / as sysdba

SQL> shutdown immediate;

SQL> startup mount

SQL> select ‘alter database rename file ‘‘‘||name||‘‘‘ to ‘‘‘||replace(name,‘SCPDB‘,‘SCPDB01‘)||‘‘‘;‘ from v$tempfile;

 

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/datafile/gmscpTemp01.dbf‘ to ‘/u01/app/oracle/oradata/SCPDB01/datafile/gmscpTemp01.dbf‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/datafile/NotifyDBTemp01.dbf‘ to ‘/u01/app/oracle/oradata/SCPDB01/datafile/NotifyDBTemp01.dbf‘;

alter database rename file ‘/u01/app/oracle/oradata/SCPDB/datafile/o1_mf_temp_ctr6mjvh_.tmp‘ to ‘/u01/app/oracle/oradata/SCPDB01/datafile/o1_mf_temp_ctr6mjvh_.tmp‘;

 

SQL> alter database open;

 

 

---修改实例名，以及数据库名

export ORACLE_SID=SCPDB

sqlplus / as sysdba

 

SQL> shutdown immediate;

SQL> startup mount

SQL> !nid target=sys/oracle dbname=SCPDB01 logfile=/tmp/change_name2SCPDB01.log

 

 

SQL> create spfile from pfile;

 

SQL> startup mount;

 

启动数据库，这个时候会报数据库名称不一致的错误，不去管他(ORA-01103: database name ‘SCPDB‘ in control file is not ‘SCPDB01‘)

 

SQL> alter system set db_name=‘SCPDB01‘ scope=spfile;

 

SQL> create pfile from spfile;

 

SQL> shutdown immediate;

 

[[email protected] ~]$ export ORACLE_SID=SCPDB01

[[email protected] ~]$ sqlplus / as sysdba

SQL> startup pfile=‘/u01/app/oracle/product/12.1.0.2/db_1/dbs/initSCPDB.ora‘；

 

SQL> create spfile from pfile=‘/u01/app/oracle/product/12.1.0.2/db_1/dbs/initSCPDB.ora‘；

 

SQL> shutdown immediate;

 

SQL> startup mount;

 

SQL> create pfile from spfile;

 

SQL> alter database open resetlogs;

 

SQL> alter system register;

 

SQL> alter user system identified by oracle;
