ℹ️ Check
Refer to the following reports produced by the TSS Data Collection: - TSSCMDS.RPT(FACLIST) - Preferred report containing all control option values in effect including default values. - TSSCMDS.RPT(TSSPRMFL) - Alternate report containing only control option values explicitly coded at TSS startup. If the NETVIEW Facility Matrix table is defined as stated below, this is not a finding. FACILITY(USERxx=NAME=NETVIEW) FACILITY(NETVIEW=MODE=FAIL) FACILITY(NETVIEW=PGM=DSI) FACILITY(NETVIEW=ACTIVE,SHRPRF,ASUBM,ABEND,MULTIUSER,NOXDEF) FACILITY(NETVIEW=LUMSG,STMSG,SIGN(M),INSTDATA,NORNDPW,AUTHINIT) FACILITY(NETVIEW=NOPROMPT,NOAUDIT,RES,WARNPW,NOTSOC,LCFTRANS,IJU) FACILITY(NETVIEW=MSGLC,NOTRACE,NOEODINIT,NODORMPW,NONPWR) FACILITY(NETVIEW=LOG(INIT,SMF,MSG,SEC9)) FACILITY(NETVIEW=DOWN=GLOBAL,LOCKTIME=00,DEFACID(NONE))
