lsnrctl start

此时可以测试两边是否连通
sqlplus sys/xxx@good as sysdba
sqlplus sys/xxx@bad as sysdba
tnsping good
tnsping bad
select * from v$instance;

startup mount;

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

startup

观察primary与standby的/u01/arch,当primary切换时，standby的归档也会增加。

primary:
alter system switch logfile;
SELECT STATUS,DESTINATION, ERROR FROM V$ARCHIVE_DEST;
select max(sequence#) from v$archived_log; --主备结果一致

alter database recover managed standby database cancel;

alter database open;

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

select open_mode from v$database;
