What is a PSU patch for Oracle Home?
Patch Set Updates (PSU) are the same cumulative patches that
include both the security fixes and priority fixes. The key with PSUs is they
are minor version upgrades (e.g., 126.96.36.199.1 to 188.8.131.52.2). Once a PSU is
applied, only PSUs can be applied in future quarters until the database is
upgraded to a new base version.
More details about PSU
