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., 22.214.171.124.1 to 126.96.36.199.2). 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
The PSU released for Oracle Database Server version 10.2.0.4.0/10.2.0.5.x , 11.1..0.7.0 and 188.8.131.52.0/184.108.40.206.0 respectively does not change the database version . That means PSU 10.2.0.4.x /10.2.0.5.x, 220.127.116.11.x, 18.104.22.168.x /22.214.171.124.x ( where x is the fifth digit ) does NOT change the 5th digit of the Oracle Database Server version.
opatch lsinventory” still shows the version as 10.2.0.4.0/10.2.0.5.0 for Oracle 10g R2, 126.96.36.199 for Oracle 11g R1 and 188.8.131.52 /184.108.40.206 for Oracle 11g R2
PSU’s also will not change the version of oracle binaries (like sqlplus, exp/imp etc.)
