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:

groupadd -g 800 oinstalluseradd -g oinstall oem

3. 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.zip

4. 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 4096oem hard nofile 4096

6. 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_HOMEexport 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:

SQL> select * from v$version;

7. 确保能够从 EM 主机顺利登录到 repository 数据库 :

[oem@vrh5 tmp]$ tnsping vrh4:1521/SBDB

TNS Ping Utility for Linux: Version 11.2.0.2.0 - Production on 16-OCT-2011 21:18:24

SQL>

8. 确保网络正常

这里要求 EM 主机必须使用 statics IP 静态 IP ，否则安装会出错， 且已正确在/etc/hosts 或 DNS 配置唯一的域

名解析

正式安装

我们开始正式通过 OUI 安装 Oracle Enterprise Manager Cloud Control 12c(12.1)，这里要用到图形化的界

面，确保 DISPLAY 环境变量正确或者使用 Xmanager 之类的软件:

(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/*.log

em_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:

SEVERE: oracle.sysman.top.oms:MDS Schema Creation is failed 创建失败是由 bug引起的

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:

在<OEL 5 上快速部署 Enterprise Manager Cloud Control 12c(12.1)> 中我介绍了如何安装配置 Oracle Enterprise Manager Cloud Control 12c(12.1) Server ，我们知道光有 EM Server 而不部署 Agent是无法发挥

其管理特性的。

接下来我们会再次通过实践了解 Em 12c(12.1)中部署 Agent 代理程序的过程，整个过程和 10g/11g Grid Control 中的 Deploy Agent 有较大的区别。

这里我们要注意一点，OMS 12c(12.1) 只能和 12.1 的 Agent 代理程序配合工作，而不能使用之前任何版本的

Agent。“Enterprise Manager Cloud Control can communicate only with Oracle Management Agent 12c and not with any other earlier release of the Management Agent. You can not configure your exising Agents to communicate with Enterprise Manager 12c OMS.”

系统和软件包要求

推荐在 Oracle Enterprise Linux 5.7 或 6.1 上安装 EM 12c 的 agent ， 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。

准备工作

1. 12c 部署 agent 要求在创建必要的 credential profile，该 credential profile将包含能够从 OMS server ssh 到目标节点 target node 的用户身份认证，且要求该用户能够在 target node 上以 sudo 执行 root 用户的

权限。

这里我们以 oracle 用户为例，我们将以目标节点上的 oracle 用户身份创建 credential profile，首先我们要确保

oracle 用户能够以 sudo 执行 root 用户的权限，这需要用到/etc/sudoers 配置文件:

!确保/usr/local/bin/sudo 这个符号链接存在

[root@vrh2 ~]# ln -s /usr/bin/sudo /usr/local/bin/sudo

[root@vrh2 m01]# ls -l /etc/sudoers-r--r----- 1 root root 3407 Oct 18 19:30 /etc/sudoers

[root@vrh2 m01]# cp /etc/sudoers /etc/sudoers.bak

打开/etc/sudoers 将以下三处修改

修改前:Defaults requiretty

修改后:Defaults:oracle !requiretty

修改前:Defaults !visiblepw

修改后:Defaults visiblepw

修改前:#### Allow root to run any commands anywhereroot ALL=(ALL) ALL

修改后

#### Allow root to run any commands anywhereroot ALL=(ALL) ALLoracle ALL=(ALL) ALL --这里加一行

以上三处修改完成后，save 文件

测试 oracle 能否正常 sudo

[root@vrh2 m01]# su - oracle

[oracle@vrh2 ~]$ ls -l /rootls: /root: Permission denied

[oracle@vrh2 ~]$ sudo ls -l /root

[sudo] password for oracle:total 88-rw------- 1 root root 1832 Aug 11 05:26 anaconda-ks.cfgdrwxr-xr-x 2 root root 4096 Aug 10 21:31 Desktop-rw-r--r-- 1 root root 56307 Aug 11 05:26 install.log-rw-r--r-- 1 root root 4136 Aug 11 05:26 install.log.syslog

2. 在目标节点上创建必要的目录 :

[root@vrh2 m01]# mkdir /m01

[root@vrh2 m01]# chown oracle:oinstall /m01

3. 确保 OMS server 和 target server 间的通信畅通，如没有使用 dns 服务 ，那么不要忘记将 host/ip 信息

写入到/etc/hosts 文件中，如果漏掉这部将报 target node can not be reached 错误

正式安装

首先再次以 sysman身份登录 EM https console，如 https://192.168.1.169:7799/em。

点击右上角的 setup-> Add Target -> Add Targets Manually

进入 Add Targets Manually 页面，选择” Add Host Target” ，并点击 Add Host …按钮:

在”add Target – Host and Platform “页面使用默认的”session name”即可，点选”+Add”按钮填入主机名和平台

信息:

注意这里推荐填入规范的 hostname，如”vrh2.oracle.com”， 注意主机名不能带下划线 “_”， 若 Platform 下拉

列表中没有你要的平台那么说明在该平台上还没有 12.1 的 agent 可用。

输入完成后点击 Next进入”Add Target - Installation Details ” 页面，点中 deployment details 出现下来菜单选

择 Fresh Agent install ，并填入 installation base directory 等目录信息。

接着在 Named confidential 点击蓝色的”+” 图形按钮，会跳出 create new Named confidential 的窗口，填入之

前配好的 oracle 用户的信息:

完成后点击 Ok,回到原”Add Target - Installation Details “界面，确认并点击 Next:

进入Review 页面，确认信息正确并点击 Deploy Agent:

完成后会进入 Agent Deployment summary 页面 ，这里存在三个阶段：

1. Initialization — 拷贝 agent 介质到目标服务器

2. Remote Prerequisite Check — 检测目标服务器的安装先决条件

3. Agent Deployment –具体的 Installation Agent 、Secure Agent 和 执行 root.sh

若一开始没有正确配置用户的 sudo ，则可能在 Remote Prerequisite Check阶段出现检测警告，例如下图:

如果一切顺利，以上三个阶段完成后 Agent即在运作了:

Agent Deployment 的日志存放在 $OMS_HOME/sysman/prov/agentpush/$date 目录下，也可以从 EM 的网页

界面上找到这些日志的具体位置。

之后点击 Target -> host 可以看到新加入的主机:

之后点击 Target -> Database -> add 添加数据库配置信息:

在 host栏填入新增加的目标服务器，并点击 continue:

EM 会自动找出目标服务器上已有的数据库, 点击 Configure 填入 dbsnmp 用户的密码后保存并 Continue:

之后点击 Target -> database 就可以看到新增的数据库了:

点击数据库名 -> 点击 Performance -> Performance Home 后可以看到新的 12c 的性能总览图:
