DG备库delay设置备库延时apply archivelog 但不延时传送归archivelog

alter database recover managed standby database delay 120 disconnect from session;
延时测试

1，在备库上运行：
alter database recover managed standby database delay 120 disconnect from session;

2，在主库上：
alter system switch logfile ;

可以看到
sys@R2> select process,status,sequence# from v$managed_standby ;

3，备库上：：

日志传送过来，当并没有运行

4，此时主库的DG状态是正常：
sys@R2> select switchover_status from v$database ;

SWITCHOVER_STATUS
----------------------------------------

5，在备库上：
alter database recover managed standby database using current logfile disconnect from session;

小结：
alter database recover managed standby database delay 120 disconnect from session;
1、能让备库延时使用归档日志

2、主库的switchover_status 显示是正常

3、并不延时传送archivelog
