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 CL/SuperSession Facility Matrix table is defined as stated below, this is not a finding.
*KLS CL/SUPERSESSION
FACILITY(USERxx=NAME=KLS)
FACILITY(KLS=MODE=FAIL,ACTIVE,SHRPRF)
FACILITY(KLS=PGM=KLV,NOASUBM,NOABEND,NOXDEF)
FACILITY(KLS=ID=xx,MULTIUSER,RES,LUMSG,STMSG,WARNPW,SIGN(M))

FACILITY(KLS=NOTSOC,LOG(INIT,SMF,MSG,SEC9))
Fix Text (F-26326r519783_fix)
Define the CT/Engine started task name KLS as a Facility to TOP SECRET in the Facility Matrix Table using the following example:
*KLS CL/SUPERSESSION
FACILITY(USERxx=NAME=KLS)
FACILITY(KLS=MODE=FAIL,ACTIVE,SHRPRF)
FACILITY(KLS=PGM=KLV,NOASUBM,NOABEND,NOXDEF)
FACILITY(KLS=ID=xx,MULTIUSER,RES,LUMSG,STMSG,WARNPW,SIGN(M))
FACILITY(KLS=NOINSTDATA,NORNDPW,AUTHINIT,NOPROMPT,NOAUDIT)
