关于RAC模式下,ibm aix hacmp的网卡配置方式进行讨论
本人现在在AIX 5。1 , ORACLE 9I RAC 生产系统已经上线运行。
现在本人在思考两个问题就是关于ORACLE RAC 模式下 HA的网卡配置情况进行分析:
1。 基于 双网卡: SERVICE , STANDBY 两块网卡,再加RS-232心跳线进行连接。
2。另外一种是:三块网卡加心跳线进行连接。 分布情况是:SERVICE,STANDBY 为PUBLIC提供生产系统的应用连接,另外再加一块网卡作“私有”只提供两台主机之间的通讯。RS-232为心跳线。
并在ORACLE中RAC参数中指定这个块专用的网卡作为RAC的内存、缓存通讯“
不知道那一种方案好一些,如果有谁也面对这样的一个问题,可以进行我进行交流与沟通。
一起成长。。。。。。。。

LearnFromOTN 回复于:2003-08-25 10:54:29 应该用专用网卡进行通讯的。
sqlplus '/ as sysdba'
SQL>oradebug setmypid
SQL>oradebug ipc
看看Tarce文件,用的什么网卡作为cache fusion的通讯网卡。
最好贴出你的Trace文件出来

starmoon2003 回复于:2003-08-25 13:13:01 我是在思考两种方式,哪一种最好,
为什么要好一些,能说出一些理由吗????
chfhy 回复于:2003-08-25 14:07:00 既然是RAC,那么我就一块网卡作“私有”只提供两台主机之间的通讯,RS-232为心跳线,其它的都为SERVICE 就行了,没有standby
chfhy 回复于:2003-08-25 14:09:22 starmoon2003:
"在ORACLE中RAC参数中指定这个块专用的网卡作为RAC的内存、缓存通讯“ 这个怎么设?我没有指定怎么也可以呀?可以讲讲吗?
