  1. “Oracle Critical Patch Updates (CPU) will now contain both the PSU and CPU, so the DBA may choose to apply just the CPU or apply all patches in the PSU patch bundle (which includes additional fixes)”Read this document 1446582.1 Once a PSU is applied, only PSUs can be applied in future quarters until the database is upgraded to a new base version
