Oracle 视图 V$RMAN_CONFIGURATION 官方解释,作用,如何使用详细说明

本站中文解释

Oracle视图V$RMAN_CONFIGURATION提供了备份和恢复中RMAN配置参数的信息,以便操作人员能够从当前的实例中查询到备份与恢复时RMAN的配置参数。用户可以使用V$RMAN_CONFIGURATION视图查看当前已设置的参数,以及检查执行备份和恢复操作时,当前备份和恢复参数是否正确。

使用V$RMAN_CONFIGURATION时,可以使用SQL语句“SELECT *from v$RMAN_CONFIGURATION “查询当前RMAN设置的各个配置参数,查看当前RMAN配置参数是否正确。同时也可以使用语句 “ALTER session SET NLS_DATE_FORMAT = ‘YYYY-MM-DD HH24:MI:SS’ “查看日期格式,以便更好地查询RMAN日志。
