oem12c_install_for_linux

一、状况描述

伴随着oracle database

12c的登场，作为DBA的工作好像越来越少，软件的功能更加智能化、人性化，不知是咱喜欢得瑟还是爱与表现，总喜欢打开的终端，在那无止境的敲打着代码，其实也挺累的。既然工具都出来了，那就用呗，效果直观还有利于管理，管理数据库不就更简单了吗。下面，咱看一下oem12c在linux的安装吧。

二、环境准备

Redhat5.4_x64+em12cr2p1+oracle11.2.0.4

在linux下安装oracle这里不再详细说明，安装之前需建好用户，配置相应系统参数、软件包。查看数据库是否可正常访问。

alter

system set processes= 500 scope=spfile;

alter

system set session_cached_cursors=500 scope=spfile;

alter

system set shared_pool_size=650M scope=spfile;

alter

system set job_queue_processes=22 scope=spfile;

alter

database add logfile size 320M;

alter

system set open_cursors=350 scope=spfile;

alter

system set sga_target=2g scope=spfile;

ALTER

SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE;

$ORACLE_HOME/bin/emca

-deconfig dbcontrol db -repos drop

三、安装过程

启动安装界面

如下图所示，由于是虚拟机安装，系统内存等不符合其安装要求，glibc软件版本低，

选择好安装目录，并填写操作系统的hostname

输入密码，至少8位，填写存储信息的数据库实例信息

检查oracle数据库参数是否符合安装要求

给出如下警告，提示你对数据库参数应设置的数值

数据库参数修改完成，查看

完成安装，虚拟机下安装该软件用了2个多小时，提示em管理、控制登录地址。

下面是oem安装后主目录下内容(我们可以看出，服务是通过weblogic管理的)

添加监控数据库

选择搜索列表

如上图所示，可添加描述信息，便于管理数据库

下图为数据库实例监控信息(由于浏览器版本低，下图通过远程登录显示内容)，这样我们能直观看出EMREP数据库信息
