          Patch Set Updates (PSUs) are proactive cumulative patches containing recommended bug fixes that are released on a regular and predictable schedule. PSUs are on the same quarterly schedule as the Critical Patch Updates (CPU), specifically the Tuesday closest to the 17th of January, April, July, and October.

          Critical Patch Updates are collections of security fixes for Oracle products. They are available to customers with valid support contracts. They are released on the Tuesday closest to the 17th day of January, April, July and October.

            Depend.

            But OPATCH ultilty handle with confilct of patchset installed.

            Patch Conflicts
            All patches may not be compatible with one another. For example, if a patch has been applied, all the bugs fixed by that patch could reappear after another patch is applied. This is called a conflict situation. OPatch detects such situations and raises an error when a it detects a conflict.

              You cannot apply a CPU patch once a PSU patch has been applied

                Hi Sir,

                Can you give some idea about conflict & relink error in Patching. Why we face these errors arises in patching?

                      Read this,
                      https://blogs.oracle.com/security/entry/the_benefits_of_database_serve

                      From the above link only,
                      The application of the Patch Set Update results in the introduction of a new baseline version for the Database Server with consequences in regards to how future patches will be applied on the system when a PSU has previously been installed. Once a PSU has been applied on the system, the recommended method to apply all future CPU program security content is to apply future PSUs. In other words, once a PSU has been applied, it is not recommended to switch back to traditional N-apply patches. While such a switch is possible with assistance from Oracle technical support, it is a complex procedure and therefore is not recommended. However, if previously only traditional N-apply CPU patches have been applied, customers can elect to apply the most current Patch Set Update at any time.

                        I need some information about patch release no's ?

                        IS it frequently updated ?

                        For ex : I applied 10.2.0.4 ( 6810189)

                        Here , patch release no is : 6810189  and  patch set  no is  10.2.0.4

                        I don't understand what it means  10.2.4.0.2

                        I don't have MOS access.

                        Please provide some information about *10.2.04 vs 10.2.4.0.2*

                        Thanks in advance ..

                          Hi,

                          Request to refer to doc "1430923.1" -- the document provides "new patch nomenclature for Oracle products".

                            You need access to MOS to download patches. Why are you worrying about PSUs if you can't download them anyway?
