Oracle 11g單實例RMAN恢復到Oracle 11g RAC
一、環境說明
操作系統版本: RHEL 6.5 x64
1. 源數據庫服務器
Oracle版本: Oracle 11g 11.2.0.4 64位(單機)
Oracle_SID: orcl
db_name :
orcl
背景：一臺生產oracle10g（10.2.0.5）數據庫計劃遷移到Oracle 11.2.0.4.0 RAC.
1)
先oracle10g（10.2.0.5）升級到Oracle 11.2.0.4（過程略）
2）再Oracle 11.2.0.4單實例遷移到Oracle
11.2.0.4 RAC集群
2. 目標數據庫服務器
操作系統：RHEL 6.8 x64 安裝註意點：
Oracle版本: Oracle 11g 11.2.0.4 RAC
64位
db_name : orcl
說明：
1）RAC與單實例的數據庫名一致，不需要重新創建一個實例或恢復一個實例,這也是需要提前考慮的內容。
2）可以直接在RAC原實例上做恢復處理，可以減少一些操作步驟，例如參數文件、口令文件等可以利用原RAC配置即可，無需要修改。
二、源DB服務器
1. 源服務器環境說明
源服務器通過執行 RMAN備份,需要執行異機RAC恢復操作。
2. 備份源數據庫
備份腳本內容
#!/bin/bash
# ScriptName:rmanbakup.sh
# Usage: backup all files in
oracle user environment.
# Creation: 2017-09-16
# Version: 1.0.0
#Define variable <You may need to change the value of
basedir.>
basedir=/u01/orabak
date=`date +%Y%m%d`
#Create pfile
sqlplus / as sysdba <<EOF
create
pfile=‘$basedir/pfile$date.ora‘ from spfile;
EOF
#RMAN BACKUP
rman target / log=$basedir/backup_all_$date.log
<<EOF
allocate channel c1 device type disk;

}
EOF
3. 備份集目錄內容

4. 把備份集傳到目標數據庫rac db1上
[[email protected] u01]# scp -r /u01/orabak

三、目的服務器上做RMAN恢復準備
1. 查看RAC磁盤掛載情況以及名稱
[[email protected] ~]# su - grid
[[email protected] ~]$ 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

2 DATA MOUNTED EXTERN 40960 39032
3 RECOVERY

2. 檢查備份集目錄以及文件權限
[[email protected] u01]# chown -R oracle:oinstall /u01/orabak
[[email protected] u01]# ll -h
/u01/orabak/
total 1.4G

4. 關閉集群參數並關閉數據庫實例準備恢復
$ sqlplus / as sysdba;
SQL> alter system set cluster_database=true scope=spfile sid=‘*‘;
$ srvctl stop database -d orcl
四、目標服務器上恢復數據
1. 啟動到nomount狀態
[[email protected] ~]$ su - oracle
[[email protected] ~]$ sqlplus / as sysdba
SQL> startup nomount;
2. 因實例名稱一致，spfile文件不需要恢復，保留原參數文件以及相關配置。
3. 口令文件也保留
4. 恢復控制文件
(1) 通過指定備份集恢復控制文件
[[email protected] ~]$ 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.

output file
name=+RECOVERY/orcl/controlfile/current.256.937131879
Finished restore at
2017/09/16 09:13:00
5. 通過備份的控制文件啟動到mount狀態
註：具體哪個文件還原控制文件，可參數源端運行 list backup of controlfile 可知。
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
6. 將備份集註冊進控制文件裏
RMAN> crosscheck backupset;
RMAN> catalog start with ‘/u01/orabak‘;
RMAN> list backup summary;

7. 查看與記錄數據庫信息
由於控制文件記錄的是原oracle10g rac數據庫文件的信息，需要記錄下來在恢復時進行修改。
(1) 查看源端數據文件及編號
$ 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

4
/u01/app/oracle/oradata/orcl/users01.dbf
5
/u01/app/oracle/oradata/orcl/tjoa.dbf
(2) 查看聯機日誌文件
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) 查看臨時文件
SQL> select name from v$tempfile;
NAME
-----------------------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf
(4) 查看源端數據文件構造RMAN RUN腳本。
SQL> set line 80
SQL> set pagesize 9999
SQL> col file_name for
a60
SQL> select ‘set newname for datafile ‘||file_id||‘ to

set newname for datafile 4

set newname for datafile 5 to ‘+DATA‘;
SQL> select ‘set newname for tempfile ‘||file_id||‘ to ‘‘‘||‘+DATA‘||‘‘‘;‘ cmd from dba_temp_files;

-----------------------------------------------------------------------------
set

8. 恢復數據文件
#通過RMAN重命名數據文件進行恢復到本地的文件系統上。
rman target /

11. 打開數據庫
采用resetlogs打開數據庫
說明：采用rman備份沒有redolog文件，以及采用恢復的控制文件進行恢復，恢復時采用不完全恢復。
需要使用resetlogs方式打開數據庫。
SQL> alter database open resetlogs;
12. 查看並修改參數
SQL> col value for a10
SQL> select * from v$option where
parameter=‘Real Application Clusters‘;
PARAMETER VALUE
-----------------------------------------------
----------
Real Application Clusters TRUE
SQL> show parameter cluster
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
cluster_database boolean
FALSE
cluster_database_instances integer
2
cluster_interconnects string
SQL> show parameter thread
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
parallel_threads_per_cpu integer
2
thread integer 1
SQL> show parameter instance_number
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
instance_number
integer 1
SQL> alter system set cluster_database=true scope=spfile
sid=‘*‘;
SQL> alter system set cluster_database_instances=2 scope=spfile
sid=‘*‘;
SQL> alter system set instance_number=1 scope=spfile
sid=‘orcl1‘;
SQL> alter system set instance_number=2 scope=spfile
sid=‘orcl2‘;
SQL> alter system set thread=1 scope=spfile
sid=‘orcl1‘;
SQL> alter system set thread=2 scope=spfile sid=‘orcl2‘;
13. 創建節點2的UNDO表空間（節點1上操作即可）
SQL> show parameter undo_tablespace
NAME TYPE
VALUE
------------------------------------ -----------
------------------------------
undo_tablespace string
UNDOTBS1
SQL> create undo tablespace UNDOTBS2 datafile
‘+DATA/orcl/datafile/undotbs02.dbf‘ size 100M;
SQL> alter system set
undo_tablespace=‘UNDOTBS2‘ scope=spfile sid=‘orcl2‘;
14. 增加節點2的REDO文件（節點1上操作即可）
alter database add logfile thread 2 group 4 (‘+DATA‘,‘+RECOVERY‘) size
50M;
alter database add logfile thread 2 group 5 (‘+DATA‘,‘+RECOVERY‘) size
50M;
alter database add logfile thread 2 group 6 (‘+DATA‘,‘+RECOVERY‘) size
50M;
alter database enable thread 2;
15. 重建temp表空間
因為在 recover 的時候不會對temp 表空間進行recover。所以recover 後，我們要手工重建temp表空間。
[[email protected] ~]# su - grid
[[email protected] ~]$ asmcmd lsof |grep temp
orcl
orcl1 +data/orcl/tempfile/temp.276.954903205
或 切換到oracle用戶
[[email protected] ~]# su - oracle
[[email protected] ~]$ sqlplus /
as sysdba
SQL> alter tablespace temp add tempfile ‘+DATA‘ size 100M;
Tablespace
altered.
SQL> select name from
v$tempfile;
NAME
--------------------------------------------------------------------------------
+DATA/orcl/tempfile/temp.276.954903205
+DATA/orcl/tempfile/temp.281.954903453
SQL> alter database tempfile ‘+DATA/orcl/tempfile/temp.276.954903205‘
offline ;
Database altered.
SQL> alter database tempfile ‘+DATA/orcl/tempfile/temp.276.954903205‘ drop
including datafiles;
alter database tempfile
‘+DATA/orcl/tempfile/temp.276.954903205‘ drop including datafiles
*
ERROR
at line 1:
ORA-25152: TEMPFILE cannot be dropped at this time
SQL> shutdown immediate;
SQL> startup
SQL> alter database tempfile ‘+DATA/orcl/tempfile/temp.276.954903205‘ drop including datafiles;
Database altered.
16. 確認實例情況
[[email protected] oracle]$ srvctl stop database -d orcl -o immediate
[[email protected]
oracle]$ srvctl start database -d orcl -o open
[[email protected] ~]$ 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、驗證數據庫及集群情況
1. 查看數據庫的狀態
[[email protected] ~]$ srvctl status database -d orcl
Instance orcl1 is running on node db1
Instance orcl2 is running on node
db2
2. 查看數據的配置情況
[[email protected] ~]$ 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
