使用三臺主機，配置相同，主機名依次爲：rac1,rac2,standby
rac1和rac2構成oracle 11.2.0.4 版本的RAC集羣，standby做備機
IP地址規劃,SCAN必須配置在DNS中

==========================開始動手=================================
在RAC和DG之間配置網絡
節點1在listener.ora中配置靜態監聽
查詢service_names，ORACLE_HOME，ORACLE_SID
SQL> show parameter service_name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string RAC
[oracle@rac1 ~]$ env | grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=RAC1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
[grid@rac1 admin]$ pwd
/u01/app/11.2.0/grid/network/admin
[grid@rac1 admin]$ vi listener.ora
修改listener.ora，在末尾填入如下內容，注意填入內容和查詢到內容有對應關係
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=RAC)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=RAC1)
)
)
重新讀取監聽配置文件
[grid@rac1 admin]$ lsnrctl reload
觀察監聽狀態
[grid@rac1 admin]$ lsnrctl status
監聽中出現下面信息，證明靜態監聽配置成功
Service "RAC" has 1 instance(s).
Instance "RAC1", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
節點2用同樣的方法配置靜態監聽
SQL> show parameter service
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string RAC
[oracle@rac2 ~]$ env | grep ORA
ORACLE_UNQNAME=RAC
ORACLE_SID=RAC2
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
[grid@rac2 ~]$ tail -10 /u01/app/11.2.0/grid/network/admin/listener.ora
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=RAC)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=RAC2)
)
)
[grid@rac2 ~]$ lsnrctl reload
[grid@rac2 ~]$ lsnrctl status
Service "RAC" has 1 instance(s).
Instance "RAC2", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
備用節點配置靜態監聽
[oracle@standby ~]$ env | grep ORA
ORACLE_UNQNAME=STANDBY
ORACLE_SID=STANDBY
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@standby ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
[oracle@standby admin]$ vi listener.ora
[oracle@standby admin]$ tail -10 listener.ora
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=STANDBY)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=STANDBY)
)
)
[oracle@standby admin]$ lsnrctl reload
[oracle@standby admin]$ lsnrctl status
Service "STANDBY" has 1 instance(s).
Instance "STANDBY", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
檢查備用節點是否能解析SCAN地址
[root@standby ~]# nslookup rac-scan.us.oracle.com
Server: 192.168.1.1
Address: 192.168.1.1#53
** server can't find rac-scan.us.oracle.com: NXDOMAIN
修改DNS客戶端配置，確保主備節點都能訪問到DNS，並進行SCAN解析
[root@standby ~]# vi /etc/resolv.conf
[root@standby ~]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 192.168.56.11
[root@standby ~]# nslookup rac-scan.us.oracle.com
Server: 192.168.56.11
Address: 192.168.56.11#53
Name: rac-scan.us.oracle.com
Address: 192.168.56.33
Name: rac-scan.us.oracle.com
Address: 192.168.56.31
Name: rac-scan.us.oracle.com
Address: 192.168.56.32
修改/etc/hosts文件保證能夠互相ping通
[root@standby ~]# cat /etc/hosts
127.0.0.1 bj localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# Public
192.168.56.11 rac1.us.oracle.com rac1

192.168.56.22 rac2-vip.us.oracle.com rac2-vip
192.168.56.51 standby.us.oracle.com standby
配置網絡服務名，支持在主數據庫和備用數據庫之間使用SCAN進行日誌傳輸和通信
[oracle@rac1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
[oracle@rac1 admin]$ vi tnsnames.ora
[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RAC)
)
)
STANDBY =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = STANDBY)
)
)
在各節點使用相同的tnsnames.ora，保證tnsping通暢
[oracle@rac1 admin]$ tnsping standby
[oracle@rac2 admin]$ tnsping standby
[oracle@standby admin]$ tnsping rac
除了已經創建的tnsnames.ora項，還需要創建支持備用數據庫RMAN實例化的項。這些項必須使用節點VIP而不是SCAN VIP，因爲這些TNS別名將被用來使用前一步創建的靜態監聽器項連接數據庫。
[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

)
STANDBY =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = STANDBY)
(INSTANCE_NAME = STANDBY)
)
)
RAC1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RAC)
(INSTANCE_NAME = RAC1)
)
)
RAC2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RAC)
(INSTANCE_NAME = RAC2)
)
)
同步tnsnames.ora文件
[oracle@rac1 admin]$ scp tnsnames.ora oracle@rac2:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
tnsnames.ora 100% 993 1.0KB/s 00:00
[oracle@rac1 admin]$ scp tnsnames.ora oracle@standby:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/
