Oracle user: oracle

Spfile: +DATA/center/spfilecenter.ora

Domain:

Start options: open

Stop options: immediate

Database role: PRIMARY

Management policy: AUTOMATIC

Server pools: center

Database instances: center1,center2

Disk Groups: DATA,FRA

Mount point paths:

Services:

Type: RAC

Database is enabled

Database is administrator managed

4. 检查节点应用状态及配置

[grid@erp1oel ~]$ srvctl status nodeapps

VIP erp1-vip is enabled

VIP erp1-vip is running on node: erp1oel

VIP erp2-vip is enabled

VIP erp2-vip is running on node: erp1oel

Network is enabled

Network is running on node: erp1oel

Network is running on node: erp2oel

GSD is disabled

GSD is not running on node: erp1oel

GSD is not running on node: erp2oel

ONS is enabled

ONS daemon is running on node: erp1oel

ONS daemon is running on node: erp2oel
[grid@erp1oel ~]$ srvctl config nodeapps -a -g -s -l

Warning:-l option has been deprecated and will be ignored.

Network exists: 1/192.168.9.0/255.255.255.0/eth0, type static

VIP exists: /erp1-vip/192.168.9.237/192.168.9.0/255.255.255.0/eth0, hosting node erp1oel

VIP exists: /erp2-vip/192.168.9.238/192.168.9.0/255.255.255.0/eth0, hosting node erp2oel

GSD exists

ONS exists: Local port 6100, remote port 6200, EM port 2016

Name: LISTENER

Network: 1, Owner: grid

Home: <CRS home>

/u01/app/11.2.0/grid on node(s) erp2oel,erp1oel

End points: TCP:1521

5. 查看ASM状态

[grid@erp1oel ~]$ srvctl status asm

ASM is running on erp1oel,erp2oel

[grid@erp1oel ~]$ srvctl config asm -a

ASM home: /u01/app/11.2.0/grid

ASM listener: LISTENER

ASM is enabled.

6. 检查TNS状态(切换oracle用户)

[oracle@erp1oel ~]$ srvctl status listener

Listener LISTENER is enabled

Listener LISTENER is running on node(s): erp1oel

7. 检查scan的状态

[oracle@erp1oel ~]$ srvctl status scan

SCAN VIP scan1 is enabled

SCAN VIP scan1 is running on node erp2oel
[oracle@erp1oel ~]$ srvctl config scan

SCAN name: erp-scan, Network: 1/192.168.9.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /erp-scan/192.168.9.239

8. RAC的启动和关闭

切换到root用户下

关闭：

crsctl stop cluster 停止本节点集群服务

crsctl stop cluster –all 停止所有节点服务

开启:

crsctl start cluster 开启本节点集群服务

crsctl start cluster –all 开启所有节点服务

RAC环境下表空间与数据文件测试

1. 查询表空间与对应数据文件位置

SQL&gt; select file_name,tablespace_name,bytes/1024/1024 m from dba_data_files;

FILE_NAME TABLESPACE_NAME M

------------------------------ ------------------------------ ----------

+DATA/center/datafile/users.25 USERS 5

9.787122435

+DATA/center/datafile/undotbs1 UNDOTBS1 60

.258.787122433

+DATA/center/datafile/sysaux.2 SYSAUX 580

57.787122433

+DATA/center/datafile/system.2 SYSTEM 720

56.787122431

FILE_NAME TABLESPACE_NAME M

------------------------------ ------------------------------ ----------

+DATA/center/datafile/example. EXAMPLE 345.625

264.787122665

+DATA/center/datafile/undotbs2 UNDOTBS2 25

.265.787123201

+DATA/center/datafile/center.2 CENTER 100

69.787188065

7 rows selected.

可以看到数据文件默认都在指定目录（+DATA/center/datafile）下

2. 创建表空间

create tablespace branch datafile '+DATA/center/datafile/branch.dbf' size 10m ;
或直接
create tablespace branch
SQL&gt; create tablespace branch;

Tablespace created.

在rac环境中可使用create tablespace tablespacename方式直接创建表空间与相应数据文件，与单实例环境中使用OMF方式类似，如在创建表空间时，未指定数据文件与其大小，默认创建数据文件大小为100m。

3. 添加数据文件

SQL&gt; alter tablespace branch add datafile;

Tablespace altered.
SQL&gt; alter tablespace branch add datafile '+DATA/center/datafile/branch.dbf1' size 10m;

Tablespace altered.

4. 删除数据文件

SQL&gt; alter tablespace branch drop datafile '+DATA/center/datafile/branch.dbf1';

Tablespace altered.

5. 删除表空间

SQL&gt; drop tablespace branch including contents and datafiles;

Tablespace dropped.

SQL&gt; drop tablespace center;

Tablespace dropped.

可以看到在单实例环境中如使用drop tablespace tablespacename 不会删除对应数据文件，但在rac环境中会自动将对应数据文件清除.
