BBI3:
FAC(USERxx=NAME=BBI3,PGM=BBM,ID=nn,ACTIVE,SHRPRF,ASUBM)
FAC(BBI3=NOABEND,MULTIUSER,NOXDEF,SIGN(S),RES,LUMSG)
FAC(BBI3=STMSG,WARNPW,NORNDPW,NOAUDIT,NOTSOC,MODE=FAIL)
FAC(BBI3=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)
✔️ Fix
The BMC Mainview for z/OS systems programmer and the ISSO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example:
**** BBI3
*
FACILITY(USERxx=NAME=BBI3,PGM=BBM,ID=nn,ACTIVE,SHRPRF)
FACILITY(BBI3=ASUBM,NOABEND,MULTIUSER,NOXDEF)
FACILITY(BBI3=LUMSG,STMSG,SIGN(S),NORNDPW)
FACILITY(BBI3=NOAUDIT,RES,WARNPW,NOTSOC)
FACILITY(BBI3=MODE=FAIL,LOG(SMF,INIT,MSG,SEC9))
FACILITY(BBI3=UIDACID=8,LOCKTIME=000)
