Feels like a problem with your log files. Either, the quoted log file is missing from its location as recorded in the controlfile of your database or it is not correctly noted in the create controlfile or create database statement if you are trying to create a new control file. Check the spelling errors. Also check the location of logfiles in your init.ora file.

Prity:

If all of your archived log file are available,
Try to see if you can recover the datafile before open the database.

alter database recover datafile <file#>;
alter database open;
