Oracle enterprise cloud control 12c的安装是一个比较复杂的过程，因为他需要依赖于Oracel database以及Oracle Weblogic。现在Oracle已经整合了Weblogic到cloud control安装包中还是省事很多，本文是基于Oracle Linux 6.3上安装Oracle enterprise cloud control 12c，以下是具体描述。

1、安装前的准备
a) os安装参考
   Virtual Box下安装Oracle Linux 6.3

b) Oracel software安装及创建DB参考
   使用yum快速部署Oracle安装环境(11g)
   Oracle Linux 6.3下安装Oracle 11g R2(11.2.0.3)

2、JAVA运行环境部署
   [root@oel64 src]# pwd
   /usr/local/src
   [root@oel64 src]# chmod u+x jdk-6u45-linux-x64-rpm.bin
   [root@oel64 src]# ./jdk-6u45-linux-x64-rpm.bin

3、 Cloud Control所需的rpm包
 Package Requirements for Oracle Management Service
     make-3.81
     binutils-2.20.51.0.2-5.11
     gcc-4.4.4
     libaio-0.3.107
     glibc-common-2.12-1
     libstdc++-4.4.4
     libXtst-1.0.99.2-3.el6.x86_64.rpm
     sysstat-9.0.4
     glibc-devel-2.12-1.7.el6.i686 (This is a 32-bit package)
     glibc-devel-2.12-1.7.el6.x86_64 (This is a 64-bit package)
     (Applicable only for Oracle Linux 6.2, which includes RH6.2 and UEK 6.2) glibc-2.12-1.47.0.2

 Package Requirements for Oracle Management Agent   
     make-3.81               
     binutils-2.20.51.0.2-5.11
     gcc-4.4.4               
     libaio-0.3.107          
     glibc-common-2.12-1.7   
     libstdc++-4.4.4         
     sysstat-9.0.4          
 
 #使用下面的方式校验rpm包
 [root@oel63 ~]# rpm -qa make binutils gcc libaio glibc-common libstdc++ sysstat --queryformat "%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n"
   glibc-common-2.12-1.132.el6_5.1(x86_64)
   sysstat-9.0.4-20.el6(x86_64)
   libaio-0.3.107-10.el6(x86_64)
   gcc-4.4.7-4.el6(x86_64)
   binutils-2.20.51.0.2-5.34.el6(x86_64)
   libstdc++-4.4.7-4.el6(x86_64)
   make-3.81-20.el6(x86_64)

 [root@oel63 ~]# rpm -qa glibc-devel --queryformat "%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n"
   glibc-devel-2.12-1.132.el6_5.1(x86_64)

   #在安装的时候出现了一个错误提示,无法找到glibc-devel-2.12-1.7-i686
 [root@oel63 ~]# yum install glibc-devel*i686
 [root@oel63 ~]# rpm -qa | grep glibc-devel
   glibc-devel-2.12-1.132.el6_5.1.i686
   glibc-devel-2.12-1.132.el6_5.1.x86_64

4、配置数据库选项 
a) 如果当前数据库配置了dbconsole，先deconfig
   [oracle@oel63 ~]$ emctl status dbconsole    #这个查询表明本机没有配置dbconsole
   OC4J Configuration issue. /u01/ora11g/db_1/oc4j/j2ee/OC4J_DBConsole_oel63.ycdata.net_ora11g not found.
   #使用下面的命令deconfig dbconsole
   $ emca -deconfig dbcontrol db -repos drop -SYS_PWD <sys pasword> -SYSMAN_PWD <sysman password> 

b) 相关参数修改 
  SQL> ALTER SYSTEM SET processes=300 SCOPE=SPFILE;

  SQL> ALTER SYSTEM SET session_cached_cursors=200 SCOPE=SPFILE;

  SQL> ALTER SYSTEM SET sga_target=2G SCOPE=SPFILE;

  SQL> ALTER SYSTEM SET shared_pool_size=600M SCOPE=SPFILE;

  SQL> ALTER SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE;

  SQL> ALTER SYSTEM SET job_queue_processes=20 SCOPE=SPFILE;

  SQL> shutdown immediate;

  SQL> startup

4、安装cloud control
  [oracle@oel63 ~]$ mkdir -p /u01/oms12cr3
  [oracle@oel63 ~]$ mkdir -p /u01/agent12cr2
  # Author: Leshami
  # Blog  : http://blog.csdn.net/leshami
  [oracle@oel63 ~]$ cd /usr/local/src/em12cc/
  [oracle@oel63 em12cc]$ ls
  em12103p1_linux64_disk1.zip  em12103p1_linux64_disk2.zip  em12103p1_linux64_disk3.zip

  [oracle@oel63 em12cc]$ unzip em12103p1_linux64_disk1.zip
  [oracle@oel63 em12cc]$ unzip em12103p1_linux64_disk2.zip
  [oracle@oel63 em12cc]$ unzip em12103p1_linux64_disk3.zip

  [oracle@oel63 em12cc]$ export DISPLAY=192.168.7.133:0.0
  [oracle@oel63 em12cc]$ ./runInstaller

  #把这2行添加到~/.bash_profile
  export OMS_HOME=/u01/oms12cr3/oms
  export AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0
  $ source ~/.bash_profile
  安装完毕后可以通过下面的URL登陆到oms https://oel63.ycdata.net:7802/em
