With z/OS 2.1, should the UNIXOPTS record default user and default group be set to null values?
Having the values set does not cause a problem in ACF2 as the values are not used for anything. But if they are set, then any ACF2 REFRESH command wil spit out WTO message: ACF79482 BPX.DEFAULT.USER values defined - They become obsolete at z/OS 2.1 and above.
To remove the values, enter the following:
change unixopts dftuser() dftgroup()
