oracle ADG启动顺序

一、oracle ADG启动顺序

1.启动主备库监听

[oracle@dgdb1 ~]$ lsnrctl start

[oracle@dgdb2 ~]$ lsnrctl start

 

2.启动备库

SQL> startup nomount

 

SQL> alter database mount standby database;

 

SQL> alter database open;

 

SQL> alter database recover managed standby database using current logfile disconnect from session;

 

3.启动主库

SQL> startup

 

4.切换主库日志

SQL> alter system switch logfile;

此时备库就会开始应用主库传输过来的归档日志

二、oracle ADG关闭顺序

1.关闭主库

SQL> shutdown immediate

 

2.取消备库应用归档日志

SQL> alter database recover managed standby database cancel;

 

3.关闭备库

SQL> shutdown immediate

 

4.关闭主备库监听

[oracle@dgdb1 ~]$ lsnrctl stop

[oracle@dgdb2 ~]$ lsnrctl stop
