Fix Text (F-18533r1_fix)
The IAO will ensure that IDMS regions (central versions) are defined with a unique userid and is properly defined to the ACP. Ensure the following items are in effect for IDMS CV logonids: - A unique logonid is associated with each IDMS CV. - Logonids of IDMS CVs that run as a started task, have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, STC Example: INSERT IDMSCV NAME(STC, IDMSCV) MUSASS NO-SMC JOBFROM MUSUPDT STC - Logonids of IDMS CVs that run as a batch job have the following attributes: MUSASS, NO-SMC, JOBFROM, MUSUPDT, RESTRICT, PGM(xxxxxxxx), SUBAUTH Example: INSERT IDMSBAT NAME(STC, IDMS BATCH) MUSASS NO-SMC JOBFROM MUSUPDT RESTRICT PGM(xxxxxxxx) SUBAUTH
