查看ADDM（数据库版本为ORACLE 10.2.0.5.0）报告时，发现其中有个结论非常不靠谱：Significant virtual memory paging was detected on the host operating system，具体内容如下所示：
FINDING 2: 100% impact (3930 seconds)
-------------------------------------
Significant virtual memory paging was detected on the host operating system.
RECOMMENDATION 1: Host Configuration, 100% benefit (3930 seconds)
ACTION: Host operating system was experiencing significant paging but no
particular root cause could be detected. Investigate processes that
do not belong to this instance running on the host that are consuming
significant amount of virtual memory. Also consider adding more
physical memory to the host.
