Explanation

Regular patches typically contain .o (object) files and/or .a (archive) libraries, and therefore require a relink of the RDBMS binary. Online patches, however, contain .so files, which are dynamic/shared libraries, and do not require a relink of the RDBMS binary. Consequently, since a relink is not needed, you can apply or roll back online patches while the RDBMS instance is running. This simplifies administration, because no downtime is needed, and also results in a much quicker turnaround time for installing or de-installing Online Patches. A regular RDBMS patch can require many minutes to install, since it requires instance shutdown, a relink, and instance startup. On the other hand, you can install an online patch in just a few Online patches are only applicable for Oracle RDBMS and not any other products. Online patches are currently supported on the following Windows and UNIX platforms for version 11.2.0.1.0 and later: About Patch Conflicts: All patches may not be compatible with one another. For example, if you apply a patch, all the bugs the patch fixes could reappear after you apply another patch. This is called a conflict situation. OPatch detects such situations and raises an error when it detects a conflict.
