How to disable RMAN backup location automatic uppercase?

User_YNBM2

Hello,

I am trying to save the backups on a software, running on windows, that creates a winfsp mount point that has case sensitive paths.

When running my RMAN backup script, it converts my disk backup locations to uppercase, which causes an error "O/S-Error: (OS 3) The system cannot find the path specified." because the mount point returns a Path Not Found error code.

Is it possible to disable this uppercase feature?

My script (backup.rman):

run {
	CONFIGURE DEFAULT DEVICE TYPE TO DISK;
	CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT = "C:\Users\user\Vawlt\folder\ORACLE_BACKUP\ora_df_%d_%c_%D%M%Y_%t_s%s_s%p";
	CONFIGURE CONTROLFILE AUTOBACKUP ON;
	CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO "C:\Users\user\Vawlt\folder\ORACLE_BACKUP\ora_cf_%F";
	CONFIGURE BACKUP OPTIMIZATION ON;
	BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
	CROSSCHECK BACKUP;
	DELETE NOPROMPT EXPIRED BACKUP;
	DELETE NOPROMPT OBSOLETE;
	CROSSCHECK ARCHIVELOG ALL;
	DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
}

Thanks in advance.

Show us the entire thing - not only the rman scriplt, but the command line that invokes rman, and the full, complete, exact (copy and paste) output.

Hey @EdStevens ,

I edited the initial post with the bat script and the backup log.

As you can see, the path that i provide is the correct path, with lower and uppercase letters. However, at the end of backup log, you can see that RMAN automatically uppercases the paths. RMAN sends a file creation request inside dir /FOLDER, and winfsp returns a file creation/path not found error because he only knows dir "/folder".

Another note: OracleUser is a windows user with administrator privileges. He is allowed to backup to a path inside the 'user' space.

Well, since this is windows, there is no case sensitivity in file/directory names. I don't know why the log is reporting it back in all caps, but I really don't think that is the issue. I'd say you are either specifying a directory that doesn't actually exist, or you have a permissions problem.

BTW, code and output are MUCH easier to read when you format it. Please see https://community.oracle.com/tech/apps-infra/kb/articles/12-format-text

@EdStevens , thank you for your answer, and sorry for the formatting.

Yeah, it's true that windows isn't case sensitive with file names, and that's why i believe RMAN converts the locations to uppercase and it just works, but not in this case.

I am pretty sure it is not a permissions problem, because I already tested writing the backup to the same mount point but using a folder with uppercase name instead (see below) and "cannot find the path specified" error was gone, but this isn't a solution I can rely on.
