1。增加重做日志文件组及大小

2。归档进程可能会有2个或者2个以上

查看log_archive_max_processes
SQL> show parameter archive_max_process
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_max_processes integer 2

如果其中一个正在归档某个日志，而另一个进程来尝试归档该日志的话，则会出现这个提示

这个提示很可能是正常的，不过，也许，你可以考虑在如何能提高归档速度方面考虑，比如日志文件的和和归档目的地的写是否存在IO上的可能的提高（比如归档目的地是raid5换做raid10等）,或者，某个归档进程出现异常或者归档目的地有问题造成归档进程阻塞而没有及时完成都是可能的。

3。 Log actively being archived by another process
这种问题在使用rman执行backup加选项plus archivelog 时候会出现.
