在测试服务器还原数据库时遇到了ORA-19563错误。如下所示
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of switch command at 04/08/2015 19:59:06ORA-19563: header validation failed for file 
[oracle@getlnx01 ~]$ oerr ora 19563
19563, 00000, "%s header validation failed for file %s"// *Cause: When opening the file to be placed in a copy or backup set,// to be inspected, or used as the target for// an incremental restore, its header was not
// recognized as a valid file header for a file of the indicated// type (data file, archived log, or control file) belonging
// to the current database.
// *Action: Ensure that the correct files are being specified for the copy// or backup operation.
通过分析后发现两个文件名冲突，原数据库有两个同名的文件invsubmat_d18.dbf位于不同分区。我还原时，由于测试服务器的空间不足，我将原路文件的恢复目录做了调整。（由于增加数据文件时粗心大意，自己给自己挖了一个大坑，而且自己跳了进去！）
如下所示，结果在/u04/oradata/epps目录下，出现了两个invsubmat_d19.dbf文件。只需在set命令里面将文件恢复路径修改即可。
run
{.................................................................
set newname for datafile 105 to "/u04/oradata/epps/invsubmat_d18.dbf";
.................................................................
set newname for datafile 109 to "/u04/oradata/epps/invsubmat_d18.dbf";
set newname for datafile 121 to "/u04/oradata/epps/ndotbs03.dbf";
set newname for datafile 122 to "/u04/oradata/epps/undotbs04.dbf";
restore database ;
switch datafile all;}
修改为如下所示，restore还原成功！
run
{.................................................................
set newname for datafile 105 to "/u04/oradata/epps/invsubmat_d18.dbf";
.................................................................
set newname for datafile 109 to "/u04/oradata/epps/invsubmat_d20.dbf";
set newname for datafile 121 to "/u04/oradata/epps/ndotbs03.dbf";
set newname for datafile 122 to "/u04/oradata/epps/undotbs04.dbf";
restore database ;
switch datafile all;}
