Directs Mainframe Access to re-read the access list from the currently active access list data set (the access list identified by the //XDBACC DD statement in the Mainframe Access startup JCL). You can update the access list by adding, removing or updating PERMIT, REJECT and ADMUSER lines, as described in the section Editing Access List Definitions in the chapter Configuration. When your updates are complete, use REFRESH ACCESSLIST to replace the currently active access list with your updated list without stopping and restarting Mainframe Access.
Here is an example of a REFRESH ACCESSLIST command and the response:
F MFA,REFRESH ACCESSLIST MFM0015I: Refresh Access List has completed
