Is It Possible to Install Only Some Fixes From Critical Patch Updates?
Critical Patch Update patches are provided as a single patch for most products, making it impossible to install a subset of fixes. Oracle E-Business Suite Release 11i fixes are typically provided individually, making it possible to install only those that are required. Patches for Oracle Database 10g Release 2 from patch set 10.2.0.3 on, and for Oracle Database 11g are composed of a number of molecules. Each molecule contains one, or a small number, of fixes. Although it is technically possible to apply only a subset of molecules, Oracle strongly recommends that this is not done unless a patch conflict is encountered.
