RMAN-06031: 無(wú)法轉(zhuǎn)換數(shù)據(jù)庫(kù)關(guān)鍵字
提示很明確，無(wú)法轉(zhuǎn)換數(shù)據(jù)庫(kù)關(guān)鍵字，造成此異常通常是因?yàn)樽址脑?
查看數(shù)據(jù)庫(kù)字符集：
SQL> select userenv('language') from dual;
USERENV('LANGUAGE')

SIMPLIFIED CHINESE_CHINA.AL32UTF8
修改注冊(cè)表regedit中NLS_LANG值，將其修改為SIMPLIFIED CHINESE_CHINA.ZHS16GBK.
此后正常顯示.
