In Portal database, with Portal version 10.1.4.0.0, it will create a broken job wwsrc_event_q_mgmt.propagate, owner is portal, interval as sysdate + 5/ (24 * 60).
This is a job that created in this version upon upgrade from Portal version 10.1.2.0.2, or 10.1.2.0.0. It suppose to be used by Enterprise Search Engines, but not implemented. Oracle purposely disabled this job during upgrade.
This is a known bug documented in Oracle Metalink Doc ID 393873.1
