libXi-1.3 (i686)

make-3.81-19.el6

sysstat-9.0.4-11.el6 (x86_64)

2、创建oracle用户和组

[root@ora12c Server]# groupadd oinstall

[root@ora12c Server]# groupadd dba

[root@ora12c Server]# useradd -g oinstall -G dba oracle

[root@ora12c Server]# passwd oracle

Changing password for user oracle.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@ora12c Server]# mkdir -p /oracle/

[root@ora12c Server]# chown -R oracle:oinstall /oracle/

[root@ora12c Server]# chmod -R 775 /oracle/

4、修改内核参数

在/etc/sysctl.conf文件下加入如下参数

[root@ora12c Server]# vim /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 2536870912

kernel.shmmni = 4096

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

/sbin/sysctl -p 使参数生效

[root@ora12c Server]# /sbin/sysctl -p

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

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

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 2

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 68719476736

kernel.shmall = 4294967296

注意：kernel.shmmax一般为物理内存的一半，SGA大小不能超过这个值，否则报错

5、修改用户限制

在/etc/security/limits.conf加入相关配置

[root@ora12c Server]# vim /etc/security/limits.conf

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft stack 10240

oracle hard stack 10240

修改文件/etc/pam.d/login，增加以下内容：

session required pam_limits.so

6、配置环境变量

在 .bash_profile配置如下变量

oracle@ora12c ~]$ vim .bash_profile

export ORACLE_BASE=/oracle/ora12c

export ORACLE_HOME=$ORACLE_BASE/db1

export ORACLE_SID=ora12c

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

export NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS";

export PATH=$ORACLE_BASE/bin:$ORACLE_HOME/bin:/bin:/sbin:/usr/ccs/bin:/usr/local/bin:$PATH

umask 022

使配置文件生效

[oracle@ora12c ~]$ source .bash_profile

后面的安装就是使用xmanager进行图形界面安装，根据界面提示一步步来就可以了。
