启用ＲＥＤＯ应用，在Ｓｔａｎｄｂｙ端查看：

好像已经删除了，但是看看操作系统下的物理文件：
ORCLPDG >host dir /u01/app/oracle/oradata/orclstd/*

ORCLPDG >host dir /u01/app/oracle/oradata/orclstd/*
/u01/app/oracle/oradata/orclstd/example01.dbf
/u01/app/oracle/oradata/orclstd/orclstd01.ctl

可见，当ｓｔａｎｄｂｙ＿ｆｉｌｅ＿ｍａｎａｇｅｍｅｎｔ＝ｍａｎｕａｌ时，在Ｐｒｉｍａｒｙ端删除时加上了ｉｎｃｌｕｄｉｎｇ　ｄａｔａｆｉｌｅｓ字句，Ｓｔａｎｄｂｙ数据库

只会将表空间和数据文件从数据字典中删除，表空间涉及的物理文件需要手工删除。
重命名表空间：
ORCLPRE >alter tablespace rmantbs offline;

Tablespace altered.

ORCLPRE >host mv /u01/rec_catalog/rmantbs.dbf /u01/rec_catalog/rmantbs01.dbf

ORCLPRE >alter tablespace rmantbs online;
alter tablespace rmantbs online
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: '/u01/rec_catalog/rmantbs.dbf'

由于在操作系统里面改过名字，无法识别。还要在数据字典里面修改数据文件路径。
ORCLPRE >alter tablespace rmantbs rename datafile
2 '/u01/rec_catalog/rmantbs.dbf'
3 to
4 '/u01/rec_catalog/rmantbs01.dbf';

Tablespace altered.

ORCLPRE >alter tablespace rmantbs online;

Tablespace altered.

ORCLPRE >select ts.name tsname,df.name dfname from v$tablespace ts,v$datafile df where ts.ts#=df.ts#;
