If you want to remove Oracle Database software from your system, then log in to the
Oracle installation user ID and use the installation procedure as follows:
/CALL-PROCEDURE INSTALL.P.ORAINST,(CMD=UNINSTALL)
In this case, the Oracle installation procedure completes the following actions:

■ Updates the Oracle inventory
■ Removes the Oracle Database software from the BS2000 file system
Note: Only the files installed by the Oracle installation procedure,
namely,
ORAINST.PRC , are removed from the system. Files created by a
user or by an Oracle instance are left in the Oracle home directory and
installation user ID.
