Oracle 11g单实例RMAN恢复到Oracle 11g RAC
一、环境说明
操作系统版本: RHEL 6.5 x64
1. 源数据库服务器
Oracle版本: Oracle 11g 11.2.0.4 64位(单机)
Oracle_SID: orcl
db_name :
orcl
背景：一台生产oracle10g（10.2.0.5）数据库计划迁移到Oracle 11.2.0.4.0 RAC.
1)
先oracle10g（10.2.0.5）升级到Oracle 11.2.0.4（过程略）
2）再Oracle 11.2.0.4单实例迁移到Oracle
11.2.0.4 RAC集群
2. 目标数据库服务器
操作系统：RHEL 6.8 x64 安装注意点：
Oracle版本: Oracle 11g 11.2.0.4 RAC
64位
Oracle_SID: orcl1 / orcl2
db_name : orcl
说明：
1）RAC与单实例的数据库名一致，不需要重新创建一个实例或恢复一个实例,这也是需要提前考虑的内容。
2）可以直接在RAC原实例上做恢复处理，可以减少一些操作步骤，例如参数文件、口令文件等可以利用原RAC配置即可，无需要修改。
二、源DB服务器
1. 源服务器环境说明
源服务器通过执行 RMAN备份,需要执行异机RAC恢复操作。
2. 备份源数据库
备份脚本内容
#!/bin/bash
# ScriptName:rmanbakup.sh
# Usage: backup all files in
oracle user environment.
# Author: koumm
# Creation: 2017-09-16
#
Version: 1.0.0
#Define variable
basedir=/u01/orabak
date=`date +%Y%m%d`
#Create pfile
sqlplus / as sysdba <
EOF
#RMAN BACKUP
rman target / log=$basedir/backup_all_$date.log

}
EOF
3. 备份集目录内容

三、目的服务器上做RMAN恢复准备
1. 查看RAC磁盘挂载情况以及名称
[root@db1 ~]# su - grid
[root@db1 ~]$ sqlplus / as sysasm
col name for a10
col state for a10
select group_number , name , state,
type, total_mb, free_mb from v$asm_diskgroup ;
SQL> select group_number , name , state, type, total_mb, free_mb from v$asm_diskgroup ;
GROUP_NUMBER NAME STATE TYPE TOTAL_MB
FREE_MB

1 CRS MOUNTED NORMAL 30720 29794
2 DATA MOUNTED EXTERN 40960 39032
3 RECOVERY
MOUNTED EXTERN 25952 24758
2. 检查备份集目录以及文件权限
[root@db1 u01]# chown -R oracle:oinstall /u01/orabak
[root@db1 u01]# ll -h
/u01/orabak/
total 1.4G
-rw-r----- 1 oracle oinstall 16M Sep 16 14:48

4. 关闭集群参数并关闭数据库实例准备恢复
$ sqlplus / as sysdba;
SQL> alter system set cluster_database=true scope=spfile sid='*';
$ srvctl stop database -d orcl
四、目标服务器上恢复数据
1. 启动到nomount状态
[oracle@db1 ~]$ su - oracle
[oracle@db1 ~]$ sqlplus / as sysdba
SQL> startup nomount;
2. 因实例名称一致，spfile文件不需要恢复，保留原参数文件以及相关配置。
3. 口令文件也保留
4. 恢复控制文件
(1) 通过指定备份集恢复控制文件
[oracle@db1 ~]$ rman target /
Recovery Manager: Release 11.2.0.4.0 - Production on Sat Sep 16 09:11:45 2017
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: ORCL (not mounted)
RMAN> restore controlfile from '/u01/orabak/ctl_ORCL_20170916_8_1';
Starting restore at 2017/09/16 09:12:58
using target database control file
instead of recovery catalog
allocated channel: ORA_DISK_1
channel
ORA_DISK_1: SID=171 instance=orcl1 device type=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore

output file
name=+RECOVERY/orcl/controlfile/current.256.937131879
Finished restore at
2017/09/16 09:13:00
5. 通过备份的控制文件启动到mount状态
注：具体哪个文件还原控制文件，可参数源端运行 list backup of controlfile 可知。
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
6. 将备份集注册进控制文件里
RMAN> crosscheck backupset;
RMAN> catalog start with '/u01/orabak';
RMAN> list backup summary;

7. 查看与记录数据库信息
由于控制文件记录的是原oracle10g rac数据库文件的信息，需要记录下来在恢复时进行修改。
(1) 查看源端数据文件及编号
$ sqlplus / as sysdba;
SQL> set pagesize 999;
SQL> set linesize 200;
SQL> col NAME
for a65
SQL> select file#,name from v$datafile;
FILE# NAME
----------
-----------------------------------------------------------------
1
/u01/app/oracle/oradata/orcl/system01.dbf
2
/u01/app/oracle/oradata/orcl/sysaux01.dbf
3
/u01/app/oracle/oradata/orcl/undotbs01.dbf
4
/u01/app/oracle/oradata/orcl/users01.dbf
5
/u01/app/oracle/oradata/orcl/tjoa.dbf
(2) 查看联机日志文件
SQL> col MEMBER for a65
SQL> select member from
v$logfile;
SQL> select member from v$logfile;
MEMBER
-----------------------------------------------------------------
/u01/app/oracle/oradata/orcl/redo03.log
/u01/app/oracle/oradata/orcl/redo02.log
/u01/app/oracle/oradata/orcl/redo01.log
(3) 查看临时文件
SQL> select name from v$tempfile;
NAME
-----------------------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf
(4) 查看源端数据文件构造RMAN RUN脚本。
SQL> set line 80
SQL> set pagesize 9999
SQL> col file_name for
a60
SQL> select 'set newname for datafile '||file_id||' to
'''||'+DATA'||''';' cmd from dba_data_files order by file_id;
CMD
-----------------------------------------------------------------------------
set
newname for datafile 1 to '+DATA';
set newname for datafile 2 to
'+DATA';
set newname for datafile 3 to '+DATA';
set newname for datafile 4
to '+DATA';
set newname for datafile 5 to '+DATA';
SQL> select 'set newname for tempfile '||file_id||' to '''||'+DATA'||''';' cmd from dba_temp_files;
CMD
-----------------------------------------------------------------------------
set
newname for tempfile 1 to '+DATA';
8. 恢复数据文件
#通过RMAN重命名数据文件进行恢复到本地的文件系统上。
rman target /
run {
set newname for datafile 1 to '+DATA';
set newname for datafile 2
to '+DATA';
set newname for datafile 3 to '+DATA';
set newname for
datafile 4 to '+DATA';
set newname for datafile 5 to '+DATA';

11. 打开数据库
采用resetlogs打开数据库
说明：采用rman备份没有redolog文件，以及采用恢复的控制文件进行恢复，恢复时采用不完全恢复。
需要使用resetlogs方式打开数据库。
SQL> alter database open resetlogs;
12. 查看并修改参数
SQL> col value for a10
SQL> select * from v$option where
parameter='Real Application Clusters';
PARAMETER VALUE
-----------------------------------------------
----------
Real Application Clusters TRUE
SQL> show parameter cluster
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
cluster_database boolean
FALSE
cluster_database_instances integer
2
cluster_interconnects string
SQL> show parameter thread
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
parallel_threads_per_cpu integer
2
thread integer 1
SQL> show parameter instance_number
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
instance_number
integer 1
SQL> alter system set cluster_database=true scope=spfile
sid='*';
SQL> alter system set cluster_database_instances=2 scope=spfile
sid='*';
SQL> alter system set instance_number=1 scope=spfile
sid='orcl1';
SQL> alter system set instance_number=2 scope=spfile
sid='orcl2';
SQL> alter system set thread=1 scope=spfile
sid='orcl1';
SQL> alter system set thread=2 scope=spfile sid='orcl2';
13. 创建节点2的UNDO表空间（节点1上操作即可）
SQL> show parameter undo_tablespace
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
undo_tablespace string
UNDOTBS1
SQL> create undo tablespace UNDOTBS2 datafile
'+DATA/orcl/datafile/undotbs02.dbf' size 100M;
SQL> alter system set
undo_tablespace='UNDOTBS2' scope=spfile sid='orcl2';
14. 增加节点2的REDO文件（节点1上操作即可）
alter database add logfile thread 2 group 4 ('+DATA','+RECOVERY') size
50M;
alter database add logfile thread 2 group 5 ('+DATA','+RECOVERY') size
50M;
alter database add logfile thread 2 group 6 ('+DATA','+RECOVERY') size
50M;
alter database enable thread 2;
15. 重建temp表空间
因为在 recover 的时候不会对temp 表空间进行recover。所以recover 后，我们要手工重建temp表空间。
[root@db1 ~]# su - grid
[grid@db1 ~]$ asmcmd lsof |grep temp
orcl
orcl1 +data/orcl/tempfile/temp.276.954903205
或 切换到oracle用户
[root@db1 ~]# su - oracle
[oracle@db1 ~]$ sqlplus /
as sysdba
SQL> alter tablespace temp add tempfile '+DATA' size 100M;
Tablespace
altered.
SQL> select name from
v$tempfile;
NAME
--------------------------------------------------------------------------------
+DATA/orcl/tempfile/temp.276.954903205
+DATA/orcl/tempfile/temp.281.954903453
SQL> alter database tempfile '+DATA/orcl/tempfile/temp.276.954903205'
offline ;
Database altered.
SQL> alter database tempfile '+DATA/orcl/tempfile/temp.276.954903205' drop
including datafiles;
alter database tempfile
'+DATA/orcl/tempfile/temp.276.954903205' drop including datafiles
*
ERROR
at line 1:
ORA-25152: TEMPFILE cannot be dropped at this time
SQL> shutdown immediate;
SQL> startup
SQL> alter database tempfile '+DATA/orcl/tempfile/temp.276.954903205' drop including datafiles;
Database altered.
16. 确认实例情况
[oracle@db1 oracle]$ srvctl stop database -d orcl -o immediate
[oracle@db1
oracle]$ srvctl start database -d orcl -o open
[oracle@db1 ~]$ sqlplus / as sysdba
SQL> col instance_name for a20
SQL> col host_name for a10
SQL>
select instance_number,instance_name ,host_name from gv$instance;
INSTANCE_NUMBER INSTANCE_NAME HOST_NAME

五、验证数据库及集群情况
1. 查看数据库的状态
[oracle@db1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node db1
Instance orcl2 is running on node
db2
2. 查看数据的配置情况
[oracle@db1 ~]$ srvctl config database -d orcl
Database unique name: orcl
Database name: orcl
Oracle home:
/u01/app/oracle/product/11.2.0/db_1
Oracle user: oracle
Spfile:
+DATA/orcl/spfileorcl.ora
Domain:
Start options: open
Stop options:
immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server
pools: orcl
Database instances: orcl1,orcl2
Disk Groups:
DATA,RECOVERY
Mount point paths:
Services:
Type: RAC
Database is
administrator managed
3. 查看集群配置
[root@db1 ~]# su - grid
[grid@db1 ~]$ crsctl stat res
