设置主机名
编辑/etc/sysconfig/network中的HOSTNAME
设置完成之后重启，永久生效
-
编辑/etc/hosts 文件
添加（ip 主机名）：
192.168.56.126 oracle11g
ip 如何快捷有效设置，参考我的经验：怎样设置虚拟机virtualbox 网关和linux ip
-
设置内核参数
1：编辑/etc/sysctl.conf
添加：
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
#kernel.shmall = 2097152
#kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl,semmns,semopm,semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
编辑完之后需要执行命令：/sbin/sysctl -p
2：编辑/etc/security/limits.conf
添加：
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 4096
oracle hard nofile 65536
oracle soft stack 10240
3：编辑/etc/pam.d/login
添加
session required pam_limits.so
4：编辑/etc/security/limits.d/90-nproc.conf
将
* soft nproc 1024
设置成
* - nproc 16384
5：编辑/etc/selinux/config
将SELINUX设置为permissive：SELINUX=permissive

编辑oracle环境
[oracle@node1 ~]$ vi .bash_profile
export ORACLE_SID=test
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
[oracle@oracle11g ~]$ source .bash_profile 使环境生效
[oracle@oracle11g ~]$ echo $ORACLE_HOME 测试是否生效
/u01/app/oracle/product/11.2.0/db_1
-
dbca 建库
建库可参考我的经验：oracle 10g(10.2.0.4) install on rhel 5 中的 dbca建库
-
netca 创建监听
[oracle@oracle11g ~]$ netca
然后一直点击 next,最后点击finish 即可
