centos5.5 x64安装oracle11g…

1、[oracle@dba ~]$ sqlplus / as sysdba
sqlplus: error while loading shared libraries:/u01/oracle/product/10.2.0/lib/libclntsh.so.11.1: cannot restoresegment prot after reloc: Permission denied
方法：
[root@dba CentOS]# service iptables stop
清除防火墙规则：                                          [确定]
把 chains 设置为 ACCEPT 策略：natfilter                  [确定]
正在卸载 Iiptables模块：                                 [确定]
[root@dba CentOS]# setenforce 0
[root@dba CentOS]# getenforce
Permissive

之后就可以登录了：sqlplus / as sysdba

2、oracle11g安装时遇到的软件问题，和系统参数和之前的10g不一样

11g：
vim /etc/sysctl.conf
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.conf.all.rp_filter = 1
fs.file-max = 6815744
fs.aio-max-nr = 1048576
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

软件问题：
centos5.5安装所需软件包

之后还是缺少：sysstat-5.0.5，镜像里没有网上下载
