Protecting data sets that have duplicate names

You can use a fully qualified generic profile to protect data sets with the same name that reside on different volumes.

Alternatively, you can use separate, discrete profiles to define data sets having the same name. Support for data sets with duplicate names allows authorized users to:
  • Move and copy RACF-protected data sets from one volume to another (for example, with the IEHMOVE system utility)
  • Establish separate discrete profiles (including the access list and statistics and logging options) for data sets having the same name
  • Protect data sets that have the same name and reside on non-shared volumes (such as SYS1.LINKLIB) on a loosely coupled system that uses a shared RACF® data set

RACF differentiates between data sets having the same name by examining the volume serial number of each separately protected data set.
