ORA-19563:  header validation failed for file
[[email protected] ~]$ 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.
After analysis, it is found that the two file names conflict, and the original database has two files invsubmat with the same name_ D18. DBF is located in different partitions. When I restore, due to the lack of space on the test server, I adjusted the recovery directory of the original file. (due to carelessness in adding data files, I dug a big hole for myself and jumped in!)
As shown below, two invsubmats appear in the / u04 / oradata / EPPs directory_ D19. DBF file. Just modify the file recovery path in the set command.
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;
}
Change to the following, restore successfully!
