SQL>select flashback_on from v$database;
FLASHBACK_ON
------------------
RESTORE POINT ONLY
SQL> alter database open;
alter database open
*
第 1 行出现错误:
ORA-38760: 此数据库实例无法启用闪回数据库
以下是解决方法:
SQL> select flashback_on from v$database;
SQL> select name from v$restore_point;
If so, drop them:
SQL> drop restore point <name>;
SQL> alter database flashback off;
SQL> select flashback_on from v$database;
SQL> alter database open;
同时建议以后多用增量备份
