10G RAC 安裝 注意事項

10G RAC 安裝 注意事項[@more@]

Oracle RAC hosts 檔案格式：

[root@rac1 racg]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
10.1.11.151 rac1
10.1.11.152 rac2

192.168.0.11 rac1-priv
192.168.0.12 rac2-priv

10.1.11.153 rac1-vip
10.1.11.154 rac2-vip
[root@rac1 racg]#

注意： 一定要有 127.0.0.1 localhost 一項，否則在配置完 ONS ， 啟動 ONS 時， 會在日誌檔案 /u01/crs/log/rac1/racg/ora.rac1.ons.log 中報以下錯誤：
