You save the security tool programs whenever you run either the Save System (SAVSYS) command or an option from the Save menu that runs the SAVSYS command.
The security tool files are in the QUSRSYS library. You should already be saving this library as part of your normal operating procedures. The QUSRSYS library contains data for many licensed programs on your system. See the Information Center for more information about what commands and options save the QUSRSYS library.
