On a 11g BIP only install you can use the QUARTZ scheduler. The scheduler is fed from the XMLP_SCHED_JOB table from the repository. It will seed either the QRTZ_SIMPLE_TRIGGERS (one off jobs) or QRTZ_CRON_TRIGGERS (repeating jobs). This will feed the QRTZ_TRIGGERS table which controls the next execution time. The actual job is in the QRTZ_JOB_DETAILS table.
You can inject jobs directly into these tables. Remember that all DateTimes are in QUARTZ_TICKS calculated back to GMT time. A ms-sql conversion function DateTime to Ticks can be foud here. From Ticks to DateTime is this one.
