Per a post from several years ago, Oracle's treatment of column names was
based on the ANSI standard which basically forbid their change after
creation.
Oracle version 8.1.7 provides commands to disable the use of and drop columns from an existing table in place. I do not remember there being a way to rename a column, but a check of the SQL manual should show if this is supported.
