rename datafile时报错ORA-01511,ORA-01121,ORA-01110
现象：
实例启动到mount之后，rename datafile时报错ORA-01511,ORA-01121,ORA-01110
SQL>
SQL> ALTER DATABASE RENAME FILE '+DATA/rac/datafile/system.416.833384105' TO '+TESTDG/rac/datafile/system.dbf';
ALTER DATABASE RENAME FILE '+DATA/rac/datafile/system.416.833384105' TO '+TESTDG/rac/datafile/system.dbf'

ERROR at line 1:
ORA-01511: error in renaming log/data files
ORA-01121: cannot rename database file 1 - file is in use or recovery
ORA-01110: data file 1: '+DATA/rac/datafile/system.416.833384105'
分析：
只所以出现这种情况因为我的DB是RAC环境，另一个节点是open状态，导致出现上面报错。
解决方案：
关闭另一个节点的实例。
