The deinstallation tool removes Oracle software and files from your system.

When you run the deinstallation tool, if the central inventory (Inventory) contains no other registered homes besides the home that you are deconfiguring and removing, then the deinstall command removes the following files and directory contents in the Oracle base directory of the Oracle Database installation owner:

• admin

• cfgtoollogs

• checkpoints

• diag

• oradata

• fast_recovery_area

Oracle strongly recommends that you configure your installations using an Optimal Flexible Architecture (OFA) configuration, and that you reserve Oracle base and Oracle home paths for exclusive use of Oracle software. If you have any user data in these locations in the Oracle base that is owned by the user account that owns the Oracle software, then the deinstallation tool deletes this data.
