克隆数据库，重新启动时发现数据库无法打开，提示有如下的错误：
SQL> startup
ORACLE instance started.

ORA-10873: file 5 needs to be either taken out of backup mode or media
recovered
ORA-01110: data file 5: '+DATA/orcl/datafile/example.265.877207037'

经检查，是因为在移动数据文件+DATA/orcl/datafile/example.265.877207037没有及时结束backup;
结束backup后，数据库可正常打开，如下：
SQL> alter tablespace example end backup;
Tablespace altered.

SQL> alter database open;
Database altered.
