Example 6. Copying using a two-stage option

In this example, you want to copy the active RACF® database to a larger database at a time when there is still some activity on your system that might result in updates to the RACF database. Because you are using the copy on a test system, not on a production system, The IRRUT400 copy does not need to be an exact copy of the active RACF database.

You do not want to use LOCKINPUT because you do not want to receive errors that result from update attempts to the active database while LOCKINPUT is in effect. Neither do you want to be subject to the unpredictable results that using NOLOCKINPUT can cause. You prefer to use a two-stage process, first using IRRUT200, then IRRUT400. You understand that the active database that is used as input to IRRUT200 and the output database from IRRUT400 will be out-of-synch if updates occur during that interval and that you will lose those updates if you decide to use the IRRUT400 copy as your active database.
