RAC+单机组建dataguard

本文描述dataguard的构建过程,使用的环境如下:

[root@rac2 ~]# cat /etc/issue

使用三台主机,配置相同,主机名依次为:rac1,rac2,standby

rac1和rac2构成oracle 11.2.0.4 版本的RAC集群,standby做备机

IP地址规划,SCAN必须配置在DNS中

==========================开始动手=================================

在RAC和DG之间配置网络

节点1在listener.ora中配置静态监听

查询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,在末尾填入如下内容,注意填入内容和查询到内容有对应关系

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(GLOBAL_DBNAME=RAC)

(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)

(SID_NAME=RAC1)

)

)


重新读取监听配置文件

[grid@rac1 admin]$ lsnrctl reload

观察监听状态

[grid@rac1 admin]$ lsnrctl status

监听中出现下面信息,证明静态监听配置成功

Service "RAC" has 1 instance(s).

Instance "RAC1", status UNKNOWN, has 1 handler(s) for this service...

The command completed successfully


节点2用同样的方法配置静态监听

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


备用节点配置静态监听

[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


检查备用节点是否能解析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客户端配置,确保主备节点都能访问到DNS,并进行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文件保证能够互相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

192.168.56.12  rac2.us.oracle.com        rac2

# Private

192.168.56.22  rac2-vip.us.oracle.com    rac2-vip


192.168.56.51  standby.us.oracle.com     standby


配置网络服务名,支持在主数据库和备用数据库之间使用SCAN进行日志传输和通信

[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)

)

)

在各节点使用相同的tnsnames.ora,保证tnsping通畅

[oracle@rac1 admin]$ tnsping standby

[oracle@rac2 admin]$ tnsping standby

[oracle@standby admin]$ tnsping rac


除了已经创建的tnsnames.ora项,还需要创建支持备用数据库RMAN实例化的项。这些项必须使用节点VIP而不是SCAN VIP,因为这些TNS别名将被用来使用前一步创建的静态监听器项连接数据库。

[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 =

(CONNECT_DATA =

(SERVICE_NAME = RAC)

)

)


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/

oracle@standby's password:

tnsnames.ora                                 100%  993     1.0KB/s   00:00
