10.2 RAC安装之clusterware

Thursday, April 10th, 2008

安装了下10.2的rac,在安装clusterware的过程中出现了一系列问题,零散的记录了下
 系统环境：
4台刀片主机(linux AS 4.4) + 牛叉存储
RAC + ASM
网络环境配置(每台主机双网卡，只需要配置public,private两个IP，VIP由vipca去虚拟，不需要配置)：
#RAC network configure
10.0.38.160       hack1
10.0.38.170       hack1-vip
192.168.0.1       hack1-priv
          
10.0.38.162       hack2
10.0.38.172       hack2-vip
192.168.0.2       hack2-priv
          
10.0.38.164       hack3
10.0.38.174       hack3-vip
192.168.0.3       hack3-priv
          
10.0.38.166       hack4
10.0.38.176       hack4-vip
192.168.0.4       hack4-priv
磁盘用途：
votedisk -> /dev/raw/raw1 -> /dev/sdb1
ocrdisk -> /dev/raw/raw2 -> /dev/sdc1
disk1 -> /dev/raw/raw3 -> /dev/sdd1
disk2 -> /dev/raw/raw4 -> /dev/sde1
/etc/sysctl.conf添加如下内容：
kernel.shmall = 2097152
kernel.shmmax = 8589934592
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max [...]

RAC最大支持100个NODE

Thursday, April 10th, 2008

今天在看11G文档，文档中说：
 Oracle Clusterware supports up to 100 nodes in a cluster on configurations running Oracle Database 10g Release 2 and later releases.
不知道，有没有人真的用过？
