Name the three major set of files on disk that compose a database in Oracle.
There are three main sets of files on disk that compose a database. All the files are binary. These are
1.) Database files
2.) Control files
3.) Redo logs
The most significant of these are the database files where the actual data resides. The control files and the redo logs support the functioning of the architecture itself. All three sets of files must be present, open, and available to Oracle for any data on the file to be useable. Without these files, you cannot access the database, and the database administrator may have to recover some or the entire database using a backup, if there is one.
