Refer to the following report 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 Ensure the BMC IOA Facility Matrix table is defined as follows: FAC(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF,ASUBM) FAC(IOA=NOABEND,MULTIUSER,NOXDEF,SIGN(S),RES,LUMSG) FAC(IOA=STMSG,WARNPW,NORNDPW,NOAUDIT,NOTSOC,MODE=FAIL) FAC(IOA=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)

Refer to the following report 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

Ensure the BMC IOA Facility Matrix table is defined as follows:

FAC(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF,ASUBM)
FAC(IOA=NOABEND,MULTIUSER,NOXDEF,SIGN(S),RES,LUMSG)
FAC(IOA=STMSG,WARNPW,NORNDPW,NOAUDIT,NOTSOC,MODE=FAIL)
FAC(IOA=LOG(SMF,INIT,MSG,SEC9),UIDACID=8,LOCKTIME=000)

Fix Text (F-300r1_fix)
The BMC IOA system programmer and the IAO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example: IOA: FACILITY(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF) FACILITY(IOA=ASUBM,NOABEND,MULTIUSER,NOXDEF) FACILITY(IOA=LUMSG,STMSG,SIGN(S),NORNDPW) FACILITY(IOA=NOAUDIT,RES,WARNPW,NOTSOC) FACILITY(IOA=MODE=FAIL,LOG(SMF,INIT,MSG,SEC9)) FACILITY(IOA=UIDACID=8,LOCKTIME=000)

Fix Text (F-300r1_fix)

The BMC IOA system programmer and the IAO will ensure that the TOP SECRET Facility Matrix Table is proper defined using the following example:

IOA:
FACILITY(USERxx=NAME=IOA,PGM=IOA,ID=nn,ACTIVE,SHRPRF)
FACILITY(IOA=ASUBM,NOABEND,MULTIUSER,NOXDEF)
FACILITY(IOA=LUMSG,STMSG,SIGN(S),NORNDPW)
FACILITY(IOA=NOAUDIT,RES,WARNPW,NOTSOC)
FACILITY(IOA=MODE=FAIL,LOG(SMF,INIT,MSG,SEC9))
FACILITY(IOA=UIDACID=8,LOCKTIME=000)
