DG备机设置mandatory归档,主机无法切出日志
由于备机新升级了硬盘,一时还没把dg(data guard)装好,就断开了主机和备机的网络,今天在手工switch logfile的时候,当切出到低18个的时候,就挂住了,长时间没有相应。
检查alertlog中,发现在不断写出如下的报错:

检查保护模式和归档情况:
sys@ORALOCAL(10.1.19.16)> select PROTECTION_MODE from v$database;

sys@ORALOCAL(10.1.19.16)> select dest_name,status,error from v$archive_dest;

发现确实由于网络断开,归档出现error。
检查等待事件:
sys@ORALOCAL(10.1.19.16)> select distinct event from v$session_wait;
EVENT
----------------------------------------------------------------
ARCH wait on ATTACH
null event
pmon timer
rdbms ipc message

wakeup time manager

----------------------------------------------------------------
ARCH wait on ATTACH
null event
pmon timer
rdbms ipc message
smon timer
switch logfile command
wakeup time manager
检查arch的归档路径,发现dg的路径是设置了mandatory:

因此原因找到:是因为将远程的归档模式设置为强制模式,而网络中断,无法实现强制归档,因此挂起,
修改成optional后即恢复正常。
alter system set log_archive_dest_2='SERVICE=standby optional' scope=both;
