RMAN-03002: failure of recover command at 06/05/2017 15:21:53
RMAN-06136: ORACLE error from auxiliary database: ORA-01861: literal does not match format string

解决方案：

将 recover tablespace CLINICS_DATA until time '2017-06-05 14:44:51' auxiliary destination '/home/oracle/auxiliary'; 中的日期格式化

RMAN> run{
2>      sql 'alter session set nls_date_format="yyyy-mm-dd hh24:mi:ss"';
3>      recover tablespace CLINICS_DATA  until time "to_date('2017-06-05 14:44:51','yyyy-mm-dd hh24:mi:ss')" auxiliary destination '/home/oracle/auxiliary';
4> }
