ORACLE11GR2 RAC服务器组建过程一 测试环境：虚拟机软件：VMWARE SERVER 2.0OS操作系统: RedHat 5 update 4 (2台)Oracle: oracle 11g r2主机名SIDETH0VIPPRIVtestdb1testdb1192.168.2.111192.168.2.11310.1.1.211testdb2testdb2192.168.2.112192.168.2.11410.1.1.212 SCANIP 192.168.2.115,192.168.2.116, 192.168.2.117SCANNAME-testdb-SCAN二、虚拟机的文件设置：修改你的虚拟机配置文件（vmware configure file）.在这个文件的最后边加上三个参数disk.locking = FALSEscsi1.sharedBus = virtualscsi1:0.mode = persistentdiskLib.dataCacheMaxSize = 0diskLib.dataCacheMaxReadAheadSize = 0diskLib.DataCacheMinReadAheadSize = 0diskLib.dataCachePageSize = 4096diskLib.maxUnsyncedWrites = 0三、DNS 配置Oracle11gr2 RAC 是使用Single Client Access Name(SCAN),所以要DNS服务器来对SCANIP进行解析。以上是对DNS服务器的相关配置。这里是把DNS服务器放在节点一中来进行解析。1. DNS服务器所需要的RPM包：bind-9.3.6-4.P1.el5_4.2bind-libs-9.3.6-4.P1.el5_4.2bind-chroot-9.3.6-4.P1.el5_4.2bind-utils-9.3.6-4.P1.el5_4.2bind-devel-9.3.6-4.P1.el5_4.2bind-sdb-9.3.6-4.P1.el5_4.2caching-nameserver-9.3.6-4.P1.el5_4.22. 对DNS主配置文件由于REDHAT5.0是用chroot来对DNS服务器的配置。所以直接去/var/named/chroot/etc/named.conf在named.conf 添加以下内容options listen-on port 53 192.168.2.111; directory /var/named; dump-file /var/named/cache_dump.db; statistics-file /var/named/data/named_stats.txt; memstatistics-file /var/named/data/named_mem_stats.txt; allow-query 192.168.2.0/24; ;include /etc/rndc.key;zone domain.com type master; file /var/named/domain.com.hosts; ;zone 2.168.192.in-addr.arpa type master; file /var/named/192.168.2.rev; ;zone 1.1.10.in-addr.arpa type master; file /var/named/10.1.1.rev; ;3. 编辑正向，反向解析配置文件DNS服务器需要对服务器的名字进行正向，反向的解释。Named 的默认目录是/var/named/chroot里面.以下是正向解释Cd /var/named/chroot/var/namedVi domain.com.hosts$ttl 86400 IN SOA testdb1.domain.com. root.domain.com.( 1282236195 10800 3600 604800 38400 ) IN NS testdb1.domain.com.testdb1.domain.com.
