安裝11202 RAC for solaris x86_64時碰到multicasting問題

在安裝11.2.0.2 RAC for Solaris x86_64環境是，節點2上執行root.sh碰到錯誤。

詳細錯誤資訊為：

OLR initialization - successful

查詢metalink後，發現問題和bug: 9974223描述的一致。

首先cssd日誌中出現了下面的資訊：

2011-04-25 11:05:00.917: [GIPCHGEN][1] gipchaNodeCreate: adding new node 1032710 { host '', haName 'CSS_racnode-cluster', srcLuid 09df7985-00000000, dstLuid 00000000-00000000 numInf 0, contigSeq 0, lastAck 0, lastValidAck 0, sendSeq [0 : 0], createTime 231687457, flags 0x1 }

隨後尋找multicasting地址：

2011-04-25 11:05:01.280: [GIPCHTHR][17] gipchaWorkerUpdateInterface: created local bootstrap interface for node 'racnode2', haName 'CSS_racnode-cluster', inf 'mcast://230.0.1.0:42424/192.168.18.129'

然後出現了通訊不成功的資訊：

2011-04-25 11:05:04.287: [ CSSD][1]clssnmvDHBValidateNCopy: node 1, , has a disk HB, but no network HB, DHB has rcfg 199191505, wrtcnt, 279, LATS 231690827, lastSeqNo 0, uniqueness 1303729178, timestamp 1303729498/231692428

這說明，Oracle無法建立PRIVATE地址間的通訊，多播地址230.0.1.0被阻塞。

利用metalink上提供的mcasttest.pl工具進行檢查，發現地址230.0.1.0失敗，但是224.0.0.251地址成功：

根據文件ID 1212703.1的描述，這種情況可以透過打Patch: 9974223來解決。

在兩個節點分別打了這個patch後，節點2上root.sh順利執行完成，cluster的安裝也順利完成。
