It is true that MTS (a performance option) is not provided on OS/390. The OS/390 version of the product has its own multitasking scheme that outperforms MTS (and predates it by a decade).

Oracle processes do not "run as a job" on OS/390. The Oracle interface on OS/390 uses cross-memory services; the application process (job or otherwise) executes its own database calls via a cross-memory PC instruction. Exceptions to this are Network clients and some types of CICS applications which exploit the aforementioned multitasking.
