Oracle introduces Patch Set Updates (PSU) for 10.2.0.4 Database

On July 14th Oracle announced on MetaLink the release of a new patching strategy for the Oracle Database.

The new Patch Set Updates (PSU) will contain cumulative patches, which contain recommended bugfixes. They will be provided on a the same quarterly basis as the Critical Patch Update (CPU), therefore release months will be January, April, July and October. The Patch Set Update will be described in the release version. E.g. 10.2.0.4.1 will be the first Patch Set Update (PSU), 10.2.0.4.2 the second PSU etc.

As described in the release information, the 10.2.0.4.1 PSU Patch (Patch 8576156) contains all the recommended patch bundles up to July 2009 (Generic, CRS, RAC, Services, DataGuard) as well as the Critical Patch Update July 2009. Moreover 5 additional critical bugfixes are included. OPatch version 10.2.0.4.7 is required for installation of PSU 10.2.0.4.1 and the PSU is rolling installable on RAC environments without downtime.

Later PSU patches can be installed on either the base release or on top of any previous PSU. For example, PSU 10.2.0.4.3 can be installed on top of Base 10.2.0.4.0, PSU 10.2.0.4.1, PSU 10.2.4.0.2.

As already mentioned, the customer has the option to install security patches only by installing the quarterly Critical Patch Update or to install security plus non-security bugfixes by installint the Patch Set Update (PSU). As the PSU 10.2.0.4.1 already contains Critical Patch Update July 2009, the documentation states that future security patches are recommended to be installed not by CPU Patches but through PSU Patches.
