一、描述
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、官網說明
根據提示查看了一下官方網站
PRVF-4664 PRVF-4657: Found inconsistent name resolution entries for SCAN name (文檔 ID 887471.1) |
Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.
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 "$GRID_HOME/bin/cluvfy comp scan" is executed, similar message will be reported.
Cause 1. SCAN name is expected to be resolved by local hosts file
SCAN name is resolved by local hosts file (/etc/hosts or %SystemRoot%\system32\drivers\etc\hosts) instead of DNS or GNS
Solution: Oracle strongly recommend to use DNS or GNS for SCAN name resolution as hosts file support only one IP for SCAN
If the intention is to use hosts file for SCAN name resolution, and ping command returns correct SCAN VIP, you can ignore the error and move forward.
If the intention is to use DNS or GNS for SCAN name resolution, comment out entries in local hosts file for SCAN name on all nodes, and re-run "$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,所以產生了這個問題,安裝的時候直接跳過這個告警就可以了。
