今天发现在主库的表上写入了数据,且做了日志切换后发现数据没有传输到备库,查看备库的alert报如下错误:
发现存放数据文件的目录/u01已经使用了100%.
2.在备库上查看日志使用情况
Select Sequence#, Name, Applied From V$archived_Log Order By Sequence#;
------------------------------------------------------------------------

35 /u02/archive_log/1_35_792174458.dbf NO
发现34和35没有使用
3.主备库腾出部分空间后,在备库上使用如下命令应用日志
recover managed standby database disconnect from session;
4.这个时候看到日志应用的进程
select process,status,sequence# from v$managed_standby;
--------------------------------------------------
PROCESS STATUS SEQUENCE#
ARCH CLOSING 34
ARCH CLOSING 35
ARCH CLOSING 31
ARCH CONNECTED 0
MRP0 APPLYING_LOG 35
RFS IDLE 0
RFS IDLE 0
RFS IDLE 36
5.再次查询备库日志应用情况
Select Sequence#, Name, Applied
From V$archived_Log Order By Sequence#;
