for sharedisk we should create sharedisk folder
for instance:
mkdir sharedisk in vmware dirctory and store scsi:1:1---1:4

ORACLE:
oracle crs software

rpm oracleasmlib-2.0.4-1.el5.i386.rpm

Install
1,linux install and setup
1.1 oracleasm rpm package install-select from list when linux installing
1.2 rpm -ivh oracleasmlib-2.0.4-1.el5.i386.rpm when linux finished
1.3 vim /etc/hosts
1.4 stop some service : sendmail, iptables,ip6tables
chkconfig --list
chkconfig --level 2345 sendmail off
1.5 check oracle user:id oracle
check system requeired for oracle from oracle document
1.6 fdisk /dev/sdb
/sdc /sdd /sde
1.7 mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
1.8 vim /etc/rc.local

2.0 shutdown linux and open folder and edit .vmx file

disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.DataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
scsi1:1.deviceType = "disk"
scsi1:2.deviceType = "disk"
scsi1:3.deviceType = "disk"
scsi1:4.deviceType = "disk"

2 setup the second nodes
1.1 cp dbrac01 dbrac02
1.2 startup linux
1.3 setup network and ip address
1.4 install vmware-tool in both nodes and restart
1.5 set up ssh
1.6 etc/init.d/oracleasm configure
1.6 install crs
建议按下列顺序执行
在 node1 上执行:/opt/ora10g/oraInventory/orainstRoot.sh;
在 node2 上执行:/opt/ora10g/oraInventory/orainstRoot.sh;
在 node1 上执行:/opt/ora10g/product/10.2.0/crs_1/root.sh;
在 node2 上执行:/opt/ora10g/product/10.2.0/crs_1/root.sh;
通常在最后一个节点执行 root.sh 时会遇到错误,就我们的情况而言当然就是 node2~~
提示:一般常见的错误有如下三种:
A).如果你碰到了这个错误:
/opt/ora10g/product/10.2.0/crs_1/jdk/jre//bin/java: error while loading shared libraries: libpthread.so.0:
cannot open shared object file: No such file or directory
可以按照如下方式解决:
===============================
修改 vipca 文件
[root@node2 opt]# vi /opt/ora10g/product/10.2.0/crs_1/bin/vipca
找到如下内容:
Remove this workaround when the bug 3937317 is fixed
arch=`uname -m`
[三思笔记]-手把手教你用 VMware 在 linux 下安装 Oracle10g RAC http://www.5ienet.com/ QQ:5454589 君三思 群:59666289
if [ "$arch" = "i686" -o "$arch" = "ia64" ]
then
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
fi
#End workaround
在 fi 后新添加一行:
unset LD_ASSUME_KERNEL
以及 srvctl 文件
[root@node2 opt]# vi /opt/ora10g/product/10.2.0/crs_1/bin/srvctl
找到如下内容:
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
同样在其后新增加一行:
unset LD_ASSUME_KERNEL
保存退出,然后在 node2 重新执行 root.sh
当然,既然我们已经知道了有这个问题,建议最好在 node2 执行 root.sh 之前,首先修改 vipca。
其实同时需要你改的还有$ORACLE_HOME/bin/srvctl 文件,不然等装完数据库之后,srvctl 命令
也是会报这个错误地。要知道 srvctl 这么常用,如果它执行老报错,那可是相当致命啊。不过呢你现
在才安装到 crs,离 create db 还远着呢,大可以等到创建完数据库,待到需要管理时再修改该文件。
B).如果你碰到了这个错误:
The given interface(s), "eth0" is not public. Public interfaces should be used to configure virtual IPs.
解决方式如下:
==============================
图形界面上运行$CRS_HOME/bin/vipca,手工重新配置 rac1-vip 和 rac2-vip。
[root@node2 opt]# xhost +
[root@node2 opt]# /opt/ora10g/product/10.2.0/crs_1/bin/vipca
C).如果你碰到了这个错误:
Error 0(Native: listNetInterfaces:[3])
[Error 0(Native: listNetInterfaces:[3])]
解决方式如下:
===============================
[root@node2 bin]# ./oifcfg iflist
eth1 10.10.17.0
virbr0 192.168.122.0
eth0 192.168.100.0
[root@node2 bin]# ./oifcfg setif -global eth0/192.168.100.0:public
[root@node2 bin]# ./oifcfg setif -global eth1/10.10.10.0:cluster_interconnect
[root@node2 bin]# ./oifcfg getif
eth0 192.168.100.0 global public
eth1 10.10.10.0 global cluster_interconnect
然后在视窗界面重新执行 vipca 即可,如上 b 例中所示。

root@node1 ~]# /opt/ora10g/product/10.2.0/crs_1/bin/./crs_stat -t
