Fix Text (F-24451r1_fix)
The Systems Programmer and IAO will review all session manager security parameters and control options for compliance. To ensure that the Session Manager generates SMF records for audit trail and accounting reports. To provide an audit trail of user activity in CL/SuperSession, configure the Network Accounting Facility (NAF) to require SMF recording of accounting and audit data. Accounting to the journal data set is optional at the discretion of the site. To accomplish this, configure the following NAF startup parameters in the KLVINNAF member of the RLSPARM initialization parameter library as follows: DSNAME= dsname Name of the NAF journal data set. Required only if the site is collecting accounting and audit data in the journal data set in addition to the SMF data. MOD If the journal data set is used, this parameter should be set to ensure that logging data in the data set is not overwritten. SMF=nnn SMF record number. This field is mandatory to ensure that CL/SuperSession data is always written to the SMF files.
