ORA-19563: header validation failed for file

在测试服务器还原数据库时遇到了ORA-19563错误。如下所示

ORA-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;

}
