oracle 11gR2 scan PRVF-4664 問題

    oracle 11gR2 rac 安裝完grid到最後一步Oracle Cluster Verification Utility post check時報錯,這是提示檢視

installActions2010-03-01_03-16-59PM.log時,日誌中記錄以下錯誤

INFO: Checking name resolution setup for "abc-cluster-scan"...
INFO: ERROR:
INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "abc-cluster-scan"
INFO: ERROR:
INFO: PRVF-4657 : Name resolution setup check for "abc-cluster-scan" (IP address: 192.168.3.227) failed

INFO: Post-check for cluster services setup was unsuccessful on all the nodes.

scan name和ip是寫在/etc/hosts中的,而沒有采用DNS或GNS

透過查詢metalink,文件ID為887471.1

Cause

Cause 1. SCAN name is resolved by hosts file instead of DNS or , this could happen even you list all SCAN IP(s) in hosts file

Solution List

For cause 1: Oracle strongly recommend to use DNS or GNS for SCAN name resolution as hosts file support only one IP for SCAN name.

If you intended to use hosts file for SCAN name resolution, and ping command returns correct SCAN VIP, you can ignore the error and move forward.

採用/etc/hosts方式的話,只能一個scan name和ip, ping scan name能返回正確ip的

話,那這個報錯可以忽略。
