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)
“I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.”
—Jimmy Carter (James Earl Carter, Jr.)
