| 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-26276r518954_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) |
