 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。
