Solution

The harmless messages can be ignored. It has been removed with
Patch for Bug 5037871, which will be supported ded in 10.2.0.3.

The prompt in Metalink of Oracle can ignore this problem. However, the concern is that if the Miss problem is accumulated here, if it exceeds misscount's
Then, the node will be evict out, which is truly reassuring.
