急，生产数据无法恢复，帮帮我.
数据库每周1,2,3,4,5备份，现在要恢复到周一的数据，先恢复到上周五的数据 restore database from tag TAG20121026T194714;
结果正常。
然后recover database until "to_date('2012-10-29 17:30:00','yyyy-mm-dd hh24:mi:ss')";
报starting media recovery
media recovery failed
RMAN-03002 failure of recover command
RMAN-11003 failure during parse /execution of sql statemenet:alter database recover if needed start until time 'OCT 29 2012 17:30:00'

另数据库有data guard.不知道对数据恢复有没有帮助？
