Both the MQ REVERIFY and TSS REFRESH commands will update the user's security environment. Both commands need security (CA Top Secret) to rebuild the environment.

The TSS REFRESH will issue fewer getmains and freemains then the MQ REVERIFY command since the ACEE on the TSS REFRESH is updated in place.
