手误 添加错了名字
先增加成员再说
SQL> alter database add logfile member '+data/myrac/onlinelog/myrac1_redolog_group6_02' to group 6;
SQL> alter database add logfile member '+data/myrac/onlinelog/myrac1_redolog_group6_01' to group 6;
删除不了
SQL> alter database drop logfile member'+DATA/myrac/onlinelog/myrac1_redolog_group6_01';
alter database drop logfile member'+DATA/myrac/onlinelog/myrac1_redolog_group6_01'

第 1 行出现错误:
ORA-00362: 要求输入成员以组成组 6 中的有效日志文件
ORA-01517: 日志成员: '+DATA/myrac/onlinelog/myrac1_redolog_group6_01'
日志状态 未使用当中啊!
