VIP hiccup
Public Network 의 hiccup (딸꾹질인데 아마도 네트웍에서 순간적으로 트여서 끊기는 현상을 말하는듯,일시적으로 INTERMEDITE로 갔다가 ONLINE으로 돌아옴) 으로 VIP 또는 SCAN 이 Fail-over 되는 되는 현상을 방지하기 위한 조치
The fix of bug 12680491 will add intermediate modifier to stop dependency between network resource and VIP to avoid unnecessary resource state change, it's included in 11.2.0.2 GI PSU4, 11.2.0.3 GI PSU3, 11.2.0.3 Windows Patch 7, 11.2.0.4 and above. This fix is recommended instead of fix for bug 12378938 to avoid the issue in first place.
