什么是OJVM PSU？
CPU: Critical Patch Update
Oracle对于其产品每个季度发行一次的安全补丁包，通常是为了修复产品中的安全隐患。
PSU: Patch Set Updates
Oracle对于其产品每个季度发行一次的补丁包，包含了bug的修复。Oracle选取被用户下载数量多的，并且被验证过具有较低风险的补丁放入到每个季度的PSU中。在每个PSU中不但包含Bug的修复而且还包含了最新的CPU。
OJVM PSU主要是针对oracle java VM。从2014年10月开始Oracle JavaVM组件作为一个单独的部分来进行安装。之前是包含在oracle rdbms psu中。
只要oracle db中安装jvm组件，就需要安装对应版本的oracle JavaVM PSU。如果只是打了rdbms的PSU，安全漏洞检查就会检查出jvm的安全漏洞。
