bdump is generated by the database for internal operations
typically these will be populated with error information

udump is generated for a specific user operation
typically these will also be error info but can contain trace info (debug)

UDUMP is where all user error logs (trace files) will be placed.

BDUMP is where all database error logs (trace files) will be placed.

CDUMP is where all OS error logs (core dump files) will be placed.
