在OEL6上至今没有解决oracle-rdbms-server-12cR1-preinstall问题，所以尝试了下OEL5，在OEL5使用OVC是没有问题的。
下面不过多介绍，请阅读OEL6上安装Oracle 12c。

1、系统信息：
[root@12c ~]# uname -a
Linux 12c.luocs.com 2.6.32-300.10.1.el5uek #1 SMP Wed Feb 22 17:37:40 EST 2012 x86_64 x86_64 x86_64 GNU/Linux

[root@12c ~]# grep MemTotal /proc/meminfo
MemTotal: 3273192 kB

[root@12c ~]# grep SwapTotal /proc/meminfo
SwapTotal: 8285752 kB

[root@12c ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 36G 3.8G 31G 12% /
/dev/sda1 99M 22M 72M 24% /boot
tmpfs 1.6G 0 1.6G 0% /dev/shm
/dev/sdb1 5.0G 5.0G 0 100% /usr/swap

这里简单说明下，我安装的OEL5 SWAP空间仍然不够大，因此我就扩展了下，扩展方法：
我在虚拟机新增一块儿5G的disk，启动后fdisk分区了下：
[root@12c ~]# fdisk -l

Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 421 3277260 82 Linux swap / Solaris
/dev/sda3 422 5221 38556000 83 Linux

Disk /dev/sdb: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 1 652 5237158+ 83 Linux

ext3格式化：
[root@12c ~]# mkfs.ext3 /dev/sdb1
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
655360 inodes, 1309289 blocks
65464 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=1342177280
40 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 31 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

创建一个目录，准备将此文件系统挂载：
[root@12c ~]# mkdir /usr/swap
[root@12c ~]# mount /dev/sdb1 /usr/swap

在/usr/swap下dd出5GB的空间
[root@12c ~]# dd if=/dev/zero of=/usr/swap/swapdisk bs=10240K count=500
dd: writing `/usr/swap/swapdisk': No space left on device
490+0 records in
489+0 records out
5128712192 bytes (5.1 GB) copied, 33.1548 seconds, 155 MB/s

创建新交换分区空间
[root@12c ~]# mkswap /usr/swap/swapdisk
Setting up swapspace version 1, size = 5128708 kB

查看原先的分区空间
[root@12c ~]# free -m
total used free shared buffers cached
Mem: 3196 2778 417 0 20 2502
-/+ buffers/cache: 255 2941
Swap: 3200 0 3200

启动新增加的swaptest的交换空间
[root@12c ~]# swapon /usr/swap/swapdisk

查看增加后的交换空间
[root@12c ~]# free -m
total used free shared buffers cached
Mem: 3196 3146 49 0 8 2885
-/+ buffers/cache: 252 2944
Swap: 8091 0 8091

将新增加交换分区空间添加进开机启动
[root@12c ~]# vi /etc/fstab
– 添加一行
/dev/sdb1 /usr/swap ext3 defaults 0 0
/usr/swap/swapdisk swap swap defaults 0 0

最后reboot重启验证

安装rlwrap
[root@12c ~]# rpm -ivh /install/rlwrap-0.37-1.el5.x86_64.rpm
warning: /install/rlwrap-0.37-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
Preparing… ########################################### [100%]
1:rlwrap ########################################### [100%]

修改/etc/hosts
[root@12c ~]# vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
192.168.80.139 12c.luocs.com 12c

配置yum源，这里我参考了http://public-yum.oracle.com，其中有如下内容：
Getting Started
1. Download and Install Oracle Linux
2. Download and copy the appropriate yum configuration file in place, by running the following commands as root:
Oracle Linux 4, Update 6 or Newer
# cd /etc/yum.repos.d
# mv Oracle-Base.repo Oracle-Base.repo.disabled
# wget http://public-yum.oracle.com/public-yum-el4.repo

Oracle Linux 5
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo

Oracle Linux 6
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo

Oracle VM 2
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ovm2.repo
3. Enable the appropriate repository by editing the yum configuration file
○ Open the yum configuration file in a text editor
○ Locate the section in the file for the repository you plan to update from, e.g. [el4_u6_base]
○ Change enabled=0 to enabled=1
4. Begin using yum, for example:
yum list
yum install firefox
You may be prompted to confirm the import of the Oracle OSS Group GPG key.

首先下载linux 5 对应的yum配置文件
[root@12c ~]# cd /etc/yum.repos.d/
[root@12c yum.repos.d]# wget http://public-yum.oracle.com/public-yum-el5.repo
–2013-06-27 10:16:02– http://public-yum.oracle.com/public-yum-el5.repo

配置文件中将enable全部启动，0改为1。

安装oracle-validated
[root@12c yum.repos.d]# yum install oracle-validated -y

安装完成之后，基本的预安装条件都已经满足了
[root@12c ~]# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba)

创建安装目录并授权
[root@12c ~]# mkdir -p /u01/app/oracle/product/12.1.0/db_1
[root@12c ~]# chown -R oracle:oinstall /u01
[root@12c ~]# chmod -R 775 /u01

配置环境变量
[oracle@12c ~]$ vi .bash_profile
export PATH
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=12c.luocs.com
export ORACLE_UNQNAME=luocs12c
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/dbhome_1
export ORACLE_SID=luocs12c
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

alias sqlplus="rlwrap sqlplus"
alias rman="rlwrap rman"

解压介质
[root@12c ~]# chown -R oracle.oinstall /install/
[root@12c ~]# su – oracle
[oracle@12c ~]$ cd /install/
[oracle@12c install]$ unzip linuxamd64_12c_database_1of2.zip
[oracle@12c install]$ unzip linuxamd64_12c_database_2of2.zip

这里我先仅安装数据库软件，然后netca配置了监听器，略

这里稍作解释，我勾选了Create As Container Database，然后选择了Create a Container Database with one or more PDBs，数量为2个，PDB Name为luocs,到时候就以luocs1、luocs2形式出现。当然，我们也可以在后续手动方式创建或者克隆出PDBs

最后简单查看，发现CDB，PDB数据库都有自己的system、sysaux、default tablespace、temp是独立的，但undo、control、redo是共享的
