【问题描述】*：我想通过增量备份LSN恢复 dm watch ，但是restore的提示
RMAN> restore database '/dm/data/dmdb/dm.ini' from backupset '/dm/bak/inc_for_st1';
restore database '/dm/data/dmdb/dm.ini' from backupset '/dm/bak/inc_for_st1';
file dm.key not found, use default license!
Error Stack
RMAN[-8372]:The operation is not supported by this backupset

备份语句如下：
backup database increment from lsn 1573875 backupset '/dm/bak/inc_for_st1';

dmwatcher 和dmserver 进程都已经关闭。
