在安裝oracle 12c rac 圖形界面的預檢查的時候總是會有一個告警，看著很不舒服，告警信息如下

INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "testE-scan"

二、官網(wǎng)說明

根據(jù)提示查看了一下官方網(wǎng)站

APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.

PURPOSE

runInstaller (OUI) reports INS-20802 while running Oracle Cluster Verification Utility post check after successful 11gR2 Grid Infrastructure clusterware (CRS) installation or upgrade:

• Installation log - $ORACLE_BASE/oraInventory/logs/installActions{$TIMESTAMP}.log

INFO: PRVG-1101 : SCAN name "cluscan.us.oracle.com" failed to resolve
INFO: ERROR:
INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "cluscan.us.oracle.com"
INFO: ERROR:
INFO: PRVF-4657 : Name resolution setup check for "scanclunm" (IP address: 10.4.0.202) failed

OR

PRCS-1016 : Failed to resolve Single Client Access Name cluscan.us.oracle.com

If "$GRID_HOME/bin/cluvfy comp scan" is executed, similar message will be reported.

DETAILS

Cause 1. SCAN name is expected to be resolved by local hosts file

SCAN name is resolved by local hosts file (/etc/hosts or %SystemRoot%\system32\drivers\etc\hosts) instead of DNS or GNS

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

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

If the intention is to use DNS or GNS for SCAN name resolution, comment out entries in local hosts file for SCAN name on all nodes, and re-run "$GRID_HOME/bin/cluvfy comp scan" to confirm.

我的環(huán)境下SCAN VIP 使用/etc/hosts文件來解析的，所以產(chǎn)生了這個問題，安裝的時候直接跳過這個告警就可以了。
