查询远程归档目录，发现状态为error

在standby端查看

SQL> show parameter remote\_listener

172.168.1.20 orclsty1-priv  
172.168.1.21 orclsty2-priv  
standby端这个参数配置的不对  
修改参数：

Alter system setremote\_listener='orclsty-cluster-scan:1521' scope=spfile sid='\*'

发现tnsnames.ora文件里

STANDBYORCL =

(DESCRIPTION =

(ADDRESS =(PROTOCOL = TCP)(HOST =  172.19.0.112)(PORT = 1521))

(CONNECT\_DATA =

(SERVER =DEDICATED)

(SERVICE\_NAME = orcl)    --配置有问题监听注册的服务为orcldg

)

监听注册的实例为orcldg如下：

\[grid@orclsty2 ~\]$ ps -ef |grep tnslsnr

修改为

STANDBYORCL =

(DESCRIPTION =

(CONNECT\_DATA =

(SERVER =DEDICATED)

(SERVICE\_NAME = orcldg)

)

切换日志发现归档还是不能传输，过一段时间发现远程归档目录有变成error

从primary通过服务STANDBYORCL连接不上备库，配置没有问题

因为我们通过scan ip地址去连接的实例的，但是我们在备端上恢复是单实例恢复的，也就是说实例还没有注册到CRS中，这是通过scan ip地址去连接，是无法连接的，注册数据库实例到集群

注册数据库

srvctl add database -d orcl -norcl -o /oracle/oracle/app/oracle/product/11.2.0/dbhome\_1-p +DATADG/orcl/spfileorcl.ora  -rphysical\_standby -a "DATADG,SYSTEMDG"

添加实例

$ srvctl add instance -d orcl -iorcl1 -n orclsty1

$ srvctl add instance -d orcl -iorcl2 -n orclsty1

重启数据库

然后再次切换日志，日志可以正常传输到standby数据库，问题解决
