Turn OFF VTAM INTERNAL TRACE OPTIONS : PSS,SMS by default

High-volume TN3270 applications are negatively impacted by this
internal trace with options PSS and SMS being active by default at VTAM start-up.
These options (at high transaction rates), cause excessive CPU utilization in the TN3270 address space, robbing capacity and impacting application performance.

    The remaining aspect of this requirement (removing PSS as a default) will not be addressed. Customers wishing to disable any of the remaining default VIT options can do so by using the VITCTRL start option and MODIFY NOTRACE commands.

    APAR OA49999 (z/OS V2R1 and V2R2) removed SMS from the list of default VIT options. PSS is still a default VIT option, but the VITCTRL start option in z/OS V2R3 allows complete control over all VIT options. VITCTRL is also available on z/OS V2R1 and z/OS V2R2 via APAR OA50271.
