注：單節點資料庫的備份已經傳送到/u02目錄下，直接執行下面的解壓即可。

[oracle@ocm18 dbs]$
2. RAC環境建立
在兩個節點操作：
cd $ORACLE_BASE/admin
mkdir orcl
cd orcl/
mkdir -p adump bdump cdump dpdump hdump pfile scripts udump
在節點1 操作：
[oracle@rac1 ~]$ cd $ORACLE_HOME/dbs
[oracle@rac1 dbs]$ orapwd file=orapworcl1 password=oracle
[oracle@rac1 dbs]$
在節點2 操作：
[oracle@rac2 ~]$ cd $ORACLE_HOME/dbs
[oracle@rac2 dbs]$ orapwd file=orapworcl2 password=oracle
[oracle@rac2 dbs]$
[oracle@rac2 ~]$ cd $ORACLE_HOME/dbs
[oracle@rac2 dbs]$ orapwd file=orapworcl2 password=oracle
[oracle@rac2 dbs]$
3. 修改初始化引數檔案
[oracle@rac1 ~]$ cp /u02/backup_db/initorcl.ora $ORACLE_HOME/dbs/initorcl1.ora
[oracle@rac1 dbs]$ vi $ORACLE_HOME/dbs/initorcl1.ora
新增:
*.cluster_database = TRUE
*.cluster_database_instances = 2
*.undo_management=AUTO
orcl1.undo_tablespace=UNDOTBS1
orcl1.instance_name=orcl1
orcl1.instance_number=1
orcl1.thread=1
orcl1.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.72.101)(PORT=1521))'
orcl2.instance_name=orcl2
orcl2.instance_number=2
orcl2.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.72.102)(PORT=1521))'
orcl2.thread=2
orcl2.undo_tablespace=UNDOTBS2
orcl2.cluster_database = TRUE
orcl2.cluster_database_instances = 2
*.cluster_database_instances = 2
*.undo_management=AUTO
orcl1.undo_tablespace=UNDOTBS1
orcl1.instance_name=orcl1
orcl1.instance_number=1
orcl1.thread=1
orcl1.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.72.101)(PORT=1521))'
orcl2.instance_name=orcl2
orcl2.instance_number=2
orcl2.local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.72.102)(PORT=1521))'
orcl2.thread=2
orcl2.undo_tablespace=UNDOTBS2
orcl2.cluster_database = TRUE
orcl2.cluster_database_instances = 2
新增的引數可以參照下面的文件：
*.cluster_database = TRUE
*.cluster_database_instances = 2
*.undo_management=AUTO
.undo_tablespace=undotbs (undo tablespace which already exists)
.instance_name=
.instance_number=1
.thread=1
.local_listener=_
.instance_name=
.instance_number=2
.local_listener=_
.thread=2
.undo_tablespace=UNDOTBS2
.cluster_database = TRUE
.cluster_database_instances = 2
*.cluster_database_instances = 2
*.undo_management=AUTO
=================================================================
4. 將資料庫由檔案系統遷移到ASM
(1) 新增和修改初始化引數
檢視存在的ASM磁碟組：
[oracle@rac1 dbs]$ export ORACLE_SID=+ASM1
[oracle@rac1 dbs]$ sqlplus / as sysdba
[oracle@rac1 dbs]$ sqlplus / as sysdba
SQL> select name from v$asm_diskgroup;
NAME
------------------------------
DATA
FRA
------------------------------
DATA
FRA
SQL>
修改和新增初始化引數：
[oracle@rac1 dbs]$ vi $ORACLE_HOME/dbs/initorcl1.ora
將
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
變為
*.db_recovery_file_dest='+FRA'
*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'
變為
*.db_recovery_file_dest='+FRA'
新增：
*.db_create_file_dest='+DATA'
*.db_create_file_dest='+DATA'
(2) 建立SPFILE
從pfile中清除 *.control_files，然後建立spfile
[oracle@rac1 dbs]$ vi $ORACLE_HOME/dbs/initorcl1.ora
刪除control_files這一行
*.control_files='/u01/app/oracle/oradata/orcl/control01.ctl','/u01/app/oracle/oradata/orcl/control02.ctl','/u01/app/oracle/oradata/orcl/control03.ctl'
[oracle@rac1 dbs]$ export ORACLE_SID=orcl1
[oracle@rac1 dbs]$ sqlplus "/as sysdba"
Connected to an idle instance.

建立日誌組和UNDO表空間，用於例項2的使用:
alter database add logfile thread 2
group 5 size 100M,
group 6 size 100M,
group 7 size 100M;
group 5 size 100M,
group 6 size 100M,
group 7 size 100M;
SQL> alter database add logfile thread 2
2 group 5 size 100M,
3 group 6 size 100M,
4 group 7 size 100M;
Database altered.
SQL> alter database open resetlogs;
Database altered.
SQL> alter database enable public thread 2;
Database altered.
SQL> CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE '+DATA';
Tablespace created.

6. 將在檔案系統存放的日誌，遷移到+ASM
alter database add logfile thread 1

group 9 size 100M;
group 8 size 100M,
group 9 size 100M;
alter database drop logfile group 2;
alter database drop logfile group 3;
alter database drop logfile group 3;
alter system switch logfile;
alter system checkpoint;
alter database drop logfile group 1;
alter database add logfile group 1 size 100m, group 2 size 100m, group 3 size 100m;
alter database drop logfile group 1;
alter database add logfile group 1 size 100m, group 2 size 100m, group 3 size 100m;

9. crs環境資訊建立
在節點1操作：
[oracle@rac1 dbs]$ export ORACLE_SID=orcl1
[oracle@rac1 dbs]$ sqlplus / as sysdba
SQL> shutdown immediate
SQL> create pfile from spfile;
SQL> create spfile='+DATA/orcl/spfileorcl.ora' from pfile;

[oracle@rac1 dbs]$ cd /u01/app/oracle/oracle/product/10.2.0/db_1/dbs
[oracle@rac1 dbs]$ rm spfileorcl1.ora
[oracle@rac1 dbs]$ echo "spfile='+DATA/orcl/spfileorcl.ora'" > initorcl1.ora
[oracle@rac1 dbs]$ rm spfileorcl1.ora
[oracle@rac1 dbs]$ echo "spfile='+DATA/orcl/spfileorcl.ora'" > initorcl1.ora
在節點2操作:
[oracle@rac2 dbs]$ cd /u01/app/oracle/oracle/product/10.2.0/db_1/dbs
[oracle@rac2 dbs]$ rm spfileorcl2.ora
rm: cannot remove `spfileorcl2.ora': No such file or directory
[oracle@rac2 dbs]$ echo "spfile='+DATA/orcl/spfileorcl.ora'" > initorcl2.ora
[oracle@rac2 dbs]$
10. 配置並啟動RAC資料庫
[oracle@rac1 dbs]$ srvctl add database -d orcl -o /u01/app/oracle/oracle/product/10.2.0/db_1
[oracle@rac1 dbs]$ srvctl add instance -d orcl -i orcl1 -n rac1
[oracle@rac1 dbs]$ srvctl add instance -d orcl -i orcl2 -n rac2
[oracle@rac1 dbs]$ srvctl add instance -d orcl -i orcl1 -n rac1
[oracle@rac1 dbs]$ srvctl add instance -d orcl -i orcl2 -n rac2
[oracle@rac1 dbs]$ srvctl modify instance -d orcl -i orcl1 -s +ASM1
[oracle@rac1 dbs]$ srvctl modify instance -d orcl -i orcl2 -s +ASM2
[oracle@rac1 dbs]$ srvctl modify instance -d orcl -i orcl2 -s +ASM2
