I think the problem is clear: the user that try to start the instance (the owner of the "oracle" binary if your are on Unix and privileges are correctly set, the user that starts the service if you are on Windows) does not have the privilege to read the control file.
Either change user or the autorizations on the file.

Why do you want to recover, for the moment and what you posted you just have to have the correct user or privileges.

Don't use a sysadmin user, use an Oracle admin one.

I don't know your environment.
I already told you what to first check: owner/group/permissions for oracle binary and control file and all directories in their path.

owner/group/permissions is not a path it is a list I meant "owner, group, permissions", that is "ls -l".

Your control files are corrupted most likely it is not a problem of privileges.

And what "Permission denied" means?

Quote:

alter database backup control file to trace;

If Oracle can't read the control file I wonder how it could execute this statement?

Please give a little polish to your Unix administration fundamentals. If you can not handle Unix do not try to handle Oracle running on it.I am sorry and my sincere apologies for being rude, but it is the basic requirement that you understand the OS first than handle Oracle.

Your control files are intact,please do not try recreating them just resolve correct file permissions on it.
