Directory Structure
Each main Oracle-oriented directory on each disk consists of a string ('u' or 'disk' by default) with a unique identifier (often a 2-digit number) appended, for example: /u01 or /disk07. Administrators store data and application-code within these directories, and Oracle products reference these directories. If desired, one can use symbolic links to map the main directories into physical disk storage.
Within each main directory a number of subdirectories can exist. Commonly-used subdirectories include:
./app/for applications./oradata/for data
For example: /u01/app/oracle/product/10.2.0/bin/ may contains the binaries for Oracle 10.2.0. If a system has an Oracle Database instance called foo, then /u01/app/oracle/admin/foo/ may contain information about that foo's datafiles: this could point to a collection of datafiles in /u03/oradata/foo, etc.

Famous quotes containing the words directory and/or structure:
“An actor who knows his business ought to be able to make the London telephone directory sound enthralling.”
—Donald Sinden (b. 1923)
“Agnosticism is a perfectly respectable and tenable philosophical position; it is not dogmatic and makes no pronouncements about the ultimate truths of the universe. It remains open to evidence and persuasion; lacking faith, it nevertheless does not deride faith. Atheism, on the other hand, is as unyielding and dogmatic about religious belief as true believers are about heathens. It tries to use reason to demolish a structure that is not built upon reason.”
—Sydney J. Harris (1917–1986)
