项目前期是在一台服务器建立了两个实例，客户端配置两个连接，现在需要把两个实例整合其中一个实例中去，要求不更改客户端的配置

背景：

项目前期是在一台服务器建立了两个实例，客户端配置两个连接，现在需要把两个实例整合其中一个实例中去，要求不更改客户端的配置。

例如

整合前有test,standby2两个实例

整合后只有standby2这个实例

之前在RAC上用srvctl配置过，还没有在单实例上配置，现在具体操作整理如下：

1、创建服务

exec dbms_service.create_service('test','test');

select t.name,t.NETWORK_NAME from v$services t;

standby2,standby2

2、设置服务立即生效

alter system set service_names='standby2,test' ;

select t.name,t.NETWORK_NAME from v$services t;

standby2,standby2

test,test

3、重新加载监听

[Oracle@standby2 ~]$ lsnrctl reload

[oracle@standby2 ~]$ lsnrctl status;
