几乎花了两个星期才装成功的，主要是由于/etc/hosts文件配的不对，装好之后觉的还蛮简单的，自己真笨，有几次差点就想放弃了。

在新的机器上安装时不需要安装oracle的任何软件，在安装gird control时会自动安装oracle软件和数据库的。

装成功的配置如下：

#add parameters to /etc/sysctl.conf

kernel.shmall = 2097152
kernel.shmmax = 536870912
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 = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144

[root@rhel131 db10g]# sysctl -p

hosts文件一定要配对，我由于没有将127.0.0.1写在这个文件，导致一直装不上。

[oracle@rhel131 ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
172.17.61.131 rhel131.hom.com rhel131


[oracle@rhel131 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

unset USERNAME

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db10g; export ORACLE_HOME
ORACLE_SID=emrep; export ORACLE_SID
PATH=.:/usr/sbin:$ORACLE_HOME/bin:$PATH; export PATH
PATH=$PATH:$ORACLE_HOME/dcm/bin:$ORACLE_HOME/opmn/bin; export PATH
PATH=$PATH:$ORACLE_HOME/Apache/Apache/bin; export PATH

#PS1="`hostname`> "
set -o emacs
set filec
