Following SYSVIEW upgrade, some users are getting this message while others are not:
GSV4202I External security checking is suspended for your user ID
it references resource rule SV.SUSP which we do not have; it does not prevent the user(s) from continuing.
SYSVIEW R14.0 - R14.2
As of SYSVIEW R14.0, there was a change made where some messages that previously were being WTO'ed are now being TPUT back to the user's session. This would be for the TSO/ISPF interface only. This may account for a behavior change where they now see the message on their screen, whereas previously it would have only showed up in the JESMSGLG of their TSO session as a WTO.
