在OOW 2011期间甲骨文发布了新一代的企业管理器Enterprise Manager Cloud Control 12c,这里我们来介绍如何在Oracle Enterprise Linux 5上快速部署EM 12c和其Agent。
硬件要求
安装Enterprise Manager Cloud Control 12c的硬件要求如下表，推荐至少有4GB内存
更多关于OS软件要求的信息，可以直接访问EM 安装手册 <Meeting Package, Kernel Parameter, and Library Requirements>章节。
准备工作
在正式部署EM 12c 之前我们需要完成一系列的准备工作，包括：
1. 下载EM 12c(12.1) 安装介质
EM 12.1的安装介质可以从Oracle技术网络OTN上找到其下载页面，64位软件的具体下载地址:
介质包括 disk1和disk2 2个接近3GB的zip压缩包，其中em12_linux64_disk1of2.zip包含了主要的EM binary，而em12_linux64_disk2of2.zip包含了为EM扩展的插件，如支持Exadata、IBM DB2的插件等。
2. 在安装EM的Host上创建EM软件的拥有者OS账号
这里我创建oem用户来执行后续的安装操作:
这里推荐新建一个11.2.0.2 版本的数据库作为EM Repository。
此外作为EM Repository的数据库还必须使用EM所要求的初始化参数，这些要求包括:
Prerequisite Checks会检测EM安装的前提条件，这里因为物理内存不足(要求3g)而出现Warning，点击Next忽略该警告
点击Yes,忽略该问题
若检测顺利，则如下图:
下一步选择create a new Enterprise Manager -> Simple ，为Middleware Home location选定一可用的空目录，注意目录的拥有者应为oem(EM 所有者用户)
选择想要安装的插件，这里我们不安装额外的插件，保持默认配置点击Next:
选择暂时不安装Exalogic Elastic Cloud Infrastructure插件, Install Later:
配置Weblogic Server，填入Weblogic和Node Manager密码及OMS instance Base Location:
配置数据库连接信息，填入repository database的连接信息:
输入 sysman用户和Agent注册使用的密码， 安装程序会自动为你提供EM所需创建表空间数据文件的位置：
选择EM 12c将要使用的端口，一般默认即可，除非这些端口有其他用途:
点击 Next后 再点击Install Now进入安装过程:
安装流程包括Copy Files、Configure Plugins Prerequisites Check、Repository Configuration、MDS Schema Configuration、OMS Configuration、Plugins Deployment and Configuration 、 Start Oracle Management Service、 Oracle Configuration Manager Repeater、Agent Configuration Assistant 、Run root scripts，总耗时在1个小时左右。
在此过程中推荐监控安装进程的日志，这些日志的位置如下:

使用如下命令停止OMS和Agent 服务:
系统和软件包要求
推荐在Oracle Enterprise Linux 5.7或6.1上安装EM 12c ， 可以从edelivery.oracle.com 下载到这2款操作系统的安装介质。
以下演示中的主机均采用Oracle Enterprise Linux 5.7 操作系统。
以下表格列出了在Oracle Linux 6或5.x上 安装EM 12c ，所要求预装的操作系统软件包，这些软件包可以直接从OS安装DVD介质中找到:
| Platform | 32-Bit Packages for 32-Bit Platform | 64-Bit Packages for 64-Bit Platform |
|---|---|---|
| Oracle Linux 6 |
|
|
| Oracle Linux 5.xRed Hat Enterprise Linux 5.x |
|
|
介质包括 disk1和disk2 2个接近3GB的zip压缩包，其中em12_linux64_disk1of2.zip包含了主要的EM binary，而em12_linux64_disk2of2.zip包含了为EM扩展的插件，如支持Exadata、IBM DB2的插件等。
2. 在安装EM的Host上创建EM软件的拥有者OS账号
这里我创建oem用户来执行后续的安装操作:
groupadd -g 800 oinstall useradd -g oinstall oem3. 解压安装介质 创建存放解压后安装介质的目录并解压上述zip包：
su - oem [oem@vrh5 tmp]$ mkdir em_cloud [oem@vrh5 tmp]$ cd em_cloud/ [oem@vrh5 em_cloud]$ unzip ../V28375-01.zip [oem@vrh5 em_cloud]$ unzip ../V28376-01.zip4. 在EM主机上安装必要的rpm 软件包以及调整/etc/sysctl.conf中的内核参数，该步骤可以通过oracle-validated工具代劳，详见<Understand Oracle Validated Configurations> 5. 为 EM拥有者用户配置必要的ulimit 参数 , 需要修改/etc/security/limits.conf配置文件，如:
[root@vrh5 ~]# tail -10 /etc/security/limits.conf #ftp hard nproc 0 #@student - maxlogins 4 # End of file oem soft nofile 4096 oem hard nofile 40966. 为EM 12c配置合适的repository database以存放数据 这里可以在Metalink上的Certification Matrix中找到EM 12c已认证的数据库版本,如下图所示 11.2.0.2和11.2.0.3 均已通过该认证:
这里推荐新建一个11.2.0.2 版本的数据库作为EM Repository。
此外作为EM Repository的数据库还必须使用EM所要求的初始化参数，这些要求包括:
Check the CBO stats gathering job Disable the stats gathering job
1.Check the processes instance parameter value
The processes instance parameter needs to be set to at least 300.
2.Check the session_cached_cursors instance parameter value.
The session_cached_cursors instance parameter should be set to 300.
Any value between 200 and 500, inclusive, will be accepted.
3.Check the job_queue_processes instance parameter value.
The job_queue_processes instance parameter should be set to 20.
4.Check the shared_pool_size instance parameter value.
The shared_pool_size instance parameter should be set to
at least 600 megabytes or roughly one third of the sga_target size.
5. Check the redo log size.
The size of the EM database instance should be 300 megabytes or greater.
Generally, there should be 3 or more redo logs available of this size.
6. Ensure that the EM tablespace has at least one datafile set to autoextensible
Add at least one datafile with the autoextend attribute to the EM tablespace
7.Check the open_cursors instance parameter value.
The open_cursors instance parameter should be set between 300 and 400, inclusive.
8.Check the sga_target instance parameter value.
The sga_target instance parameter should be set to at least 2 gigabytes, and
roughly twice the size of the pga_aggregate_target setting.
9.Check for invalid objects in the EM repository
Compile all invalid objects in the EM repository
可以通过以下命令满足上述的参数要求，当然参数的值还可以适当放大:
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;注意EM 要求 repository database没有配置DB control ，如果有的话需要通过下列命令drop 掉:
export ORACLE_HOME= $YOUR_ORACLE_HOME export ORACLE_SID= $Repository_SID $ORACLE_HOME/bin/emca -deconfig dbcontrol db -repos drop同时要求sysman 和 sysman_mds、 sysman_opss用户不存在，已创建该用户的DB 可以drop 掉:

(oem)$ unset ORACLE_HOME ORACLE_BASE ORACLE_SID (oem)$ export DISPLAY=:0 (oem)$ cd /tmp/em_cloud/ 注意这里若你的EM Host拥有多个host name ,那么要使用ORACLE_HOSTNAME参数指定规范的host name 如/etc/hosts 中的信息为： 192.168.1.8 vrh5 vrh5.oracle.com 那么要选用vrh5.oracle.com 这个hostname 如果host name 中带"_"符号 可能导致安装失败 (oem)$ ./runInstaller ORACLE_HOSTNAME=vrh5.oracle.com Starting Oracle Universal Installer…如下图OUI界面顺利启动，勾销" I wish to receive security update..."，并点击Next:
Prerequisite Checks会检测EM安装的前提条件，这里因为物理内存不足(要求3g)而出现Warning，点击Next忽略该警告
点击Yes,忽略该问题
若检测顺利，则如下图:
下一步选择create a new Enterprise Manager -> Simple ，为Middleware Home location选定一可用的空目录，注意目录的拥有者应为oem(EM 所有者用户)
选择想要安装的插件，这里我们不安装额外的插件，保持默认配置点击Next:
选择暂时不安装Exalogic Elastic Cloud Infrastructure插件, Install Later:
配置Weblogic Server，填入Weblogic和Node Manager密码及OMS instance Base Location:
配置数据库连接信息，填入repository database的连接信息:
输入 sysman用户和Agent注册使用的密码， 安装程序会自动为你提供EM所需创建表空间数据文件的位置：
选择EM 12c将要使用的端口，一般默认即可，除非这些端口有其他用途:
点击 Next后 再点击Install Now进入安装过程:
安装流程包括Copy Files、Configure Plugins Prerequisites Check、Repository Configuration、MDS Schema Configuration、OMS Configuration、Plugins Deployment and Configuration 、 Start Oracle Management Service、 Oracle Configuration Manager Repeater、Agent Configuration Assistant 、Run root scripts，总耗时在1个小时左右。
在此过程中推荐监控安装进程的日志，这些日志的位置如下:
例如: /m01/midd/oms/sysman/log/schemamanager/m_$date/m_$date.CREATE/em_repos_config.log /m01/midd/oms/sysman/log/schemamanager/m_$date/m_$date.CREATE/emschema.log /m01/midd/oms/cfgtoollogs/cfgfw/oracle.sysman.top.oms_*.log /m01/midd/oms/cfgtoollogs/omsca/*.logem_repos_config.log记录了em repository的配置日志，在此安装过程中可能遇到如下错误:

遇到该错误后，手动登录到数据库并执行以下create user命令:
create user SYSMAN_MDS identified by sysman_mds;创建该SYSMAN_MDS用户后，回到安装界面并点击retry按钮，安装会继续下去。 OMS和Agent配置过程中的日志如下:
