4、  oracle裡的補丁具體分為哪幾種型別？

答：oracle裡的補丁具體分為如下這樣6種型別：

Oracle Interim patches:  A patch that is applied in between patchset releases with the Opatch utility.  Interim patches are sometimes also referred to as patchset exceptions.

Oracle Merge patches: A type of interim patch that merges multiple fixes to ensure that one fix doesn't overwrite the other. Merge patches are typically required when a conflict is detected between an existing patch and a new patch. 

Oracle Bundle patches: A type of interim patch that contains fixes to many important bugs, though not as many as a patchset.

Oracle Critical Patch Update (CPU) patches:  A type of interim patch that contains fixes to critical security bugs delivered on a quarterly basis.

Patch Set Updates(PSUs) : 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 15th of January, April, July, and October.

Oracle Patchsets: Software-release mechanisms for delivering tested and integrated product fixes on a regular basis.
