ORACLE19.8 RAC搭建ADG-主备都在原主机上 静态监听

ORACLE19.8 RAC搭建ADG-主备都在原主机上配置关于PDB连接

标签： oracle19c

我们知道多租户环境下，pdb中建立的普通用户连接pdb需要通过tnsnames.ora或ezconnect的方式连接。而pdb的连接需要通过IP、端口和PDB服务名来连接，那么相同主机adg的情况下，备库的IP和PDB和主库是完全相同的。所以我们只能考虑通过区分端口来进行主备pdb的连接。

配置需要考虑如下步骤:

1.grid通过netca创建新的监听服务比如DGLISTENER,端口为2521（不能使用主机已经占用的端口）

2.grid用户创建好新的监听后，修改监听文件添加静态注册参数:

节点1添加实例1的名称：

重启监听：
 

srvctl stop listener -l LISTENER
 srvctl stop listener -l DGLISTENER
 srvctl start listener -l LISTENER
 srvctl start listener -l DGLISTENER
 

检查服务：
 

lsnrctl status LISTENER
 lsnrctl status DGLISTENER

tnsping 服务名测试，确认OK：

4.修改LOCAL_LISTENER、remote_listener
 

增加scan listener端口
 

srvctl modify scan_listener -endpoints "TCP:1521/TCP:2521"
 

节点1：
 export ORACLE_SID=orcl1
 sqlplus / as sysdba
 alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.183)(PORT=1521))' scope=both sid='orcl1';
 alter system set remote_listener ='rac-scan:1521' scope=both sid='orcl1';
 export ORACLE_SID=dgorcl1
 sqlplus / as sysdba
 alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.183)(PORT=2521))' scope=both sid='dgorcl1';
 alter system set remote_listener ='rac-scan:2521' scope=both sid='dgorcl1';
 

节点2：
 export ORACLE_SID=orcl2
 sqlplus / as sysdba
 alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.184)(PORT=1521))' scope=both sid='orcl2';
 alter system set remote_listener ='rac-scan:1521' scope=both sid='orcl2';
 export ORACLE_SID=dgorcl2
 sqlplus / as sysdba
 alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.184)(PORT=2521))' scope=both sid='dgorcl2';
 alter system set remote_listener ='rac-scan:2521' scope=both sid='dgorcl2';
 

 

 

 

 

 

 

 

 

 

 

重启监听：
 

srvctl stop listener -l LISTENER
 srvctl stop listener -l DGLISTENER
 srvctl start listener -l LISTENER
 srvctl start listener -l DGLISTENER
 

检查服务,确认端口1521只监听主库的服务，2521只监听备库的服务，基本就没问题了。一般测试过程结合数据库后台日志alert查看是否有异常，根据问题再排查处理即可。
 

lsnrctl status LISTENER
 lsnrctl status DGLISTENER
 

 

 

 

5.测试连接：
 

sqlplus sys/oracle@orcl as sysdba
 sqlplus sys/oracle@dgorcl as sysdba
 sqlplus jyc/jyc@dgorcl_pdb
 sqlplus jyc/jyc@dgorcl_jyc
 

 

 

 

[oracle@rac1 ~]$ sqlplus sys/oracle@dgorcl as sysdba
