监控正在运行的rman过程

如果怀疑rman性能问题

REM -------------------------------
REM Script to monitor rman backup/restore operations
REM To run from sqlplus: @monitor ''
REM Example:
--SQL>spool monitor.out
--SQL>@monitor 'yyyy-mm-dd 16:38:03'
REM where <date> is the start time of your rman backup or restore job
REM Run monitor script periodically to confirm rman is progessing

SQL> @mon '2021-11-11 20:30:00'
这个时间表示备份开始的大致时间即可，可多次执行。
