需求：安装部署OEM 13.2
环境：两台主机，系统RHEL 6.5，分别部署OMS和OMR：
OMS，也就是OEMCC的服务端 IP：192.168.1.88 内存：12G+ 硬盘：100G+
OMR，也就是OEM底层的资料库 IP：192.168.1.89 内存：8G+ 硬盘：100G+
步骤：
参考文档：
1.准备安装介质
需要下载的介质： - http://www.oracle.com/technetwork/oem/enterprise-manager/downloads/index.htmlOEMCC 13.2.0.0 介质(8G)：
em13200p1_linux64.bin
em13200p1_linux64-2.zip
em13200p1_linux64-3.zip
em13200p1_linux64-4.zip
em13200p1_linux64-5.zip
em13200p1_linux64-6.zip
em13200p1_linux64-7.zip
dbca建库模板文件(360M):
12.1.0.2.0_Database_Template_for_EM13_2_0_0_0_Linux_x64.zip
Oracle 12.1.0.2 介质(2.5G)：
linuxamd64_12102_database_1of2.zip
linuxamd64_12102_database_2of2.zip
总共大概要下载11G大小的安装介质。这同时也反映出OEM的庞大。
2.OMR：安装Oracle 12.1.0.2软件
这一步就是安装12.1.0.2的数据库软件，可以参考： - [Linux平台Oracle 12.1.0.2 单实例安装部署](http://www.cnblogs.com/jyzhao/p/8318547.html)注：选用12.1.0.2版本的软件，是因为OEM13.2提供的资料库模板是12.1.0.2版本的。
3.OMR：使用OEM模板dbca建库
使用Oracle提供的EM模板`12.1.0.2.0_Database_Template_for_EM13_2_0_0_0_Linux_x64.zip`，dbca创建需要的资料库oemrepo实例：3.1 将模板文件拷贝到Oracle数据库的DBCA模板目录下并解压：
DBCA的模板目录位于：$ORACLE_HOME/assistants/dbca/templates/
[oracle@OMR u01]$ cd $ORACLE_HOME/assistants/dbca/templates/
[oracle@OMR templates]$ pwd
/u01/app/oracle/product/12.1.0/dbhome_1/assistants/dbca/templates
[oracle@OMR templates]$ cp /u01/12.1.0.2.0_Database_Template_for_EM13_2_0_0_0_Linux_x64.zip ./
[oracle@OMR templates]$ unzip 12.1.0.2.0_Database_Template_for_EM13_2_0_0_0_Linux_x64.zip
[oracle@OMR templates]$ ls -lrth

3.2 dbca创建资料库oemrepo实例的关键步骤：
第2步：选择高级选项
第3步：可以看到多出的3个模板，根据需求，我这里选择small的
第6步：输入统一密码，我这里是OEMrepo123
第13步：安装概览
第15步：完成实例oemrepo的安装
最后使用netca创建监听，至此OMR的所有操作就已经完成了。
4.OMS：安装部署OEM13.2
4.1 创建oracle用户
groupadd -g 501 oinstall
groupadd -g 502 dba
useradd -u 502 -g oinstall -G dba oracle
4.2 安装依赖的rpm软件包
直接使用yum安装所有需要的软件包：
yum install -y binutils.x86_64 compat-libcap1.x86_64 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64 gcc.x86_64 gcc-c++.x86_64 glibc.x86_64 glibc.i686 glibc-devel.x86_64 glibc-devel.i686 ksh.x86_64 libgcc.x86_64 libgcc.i686 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.i686 libstdc++-devel.x86_64 libaio.x86_64 libaio.i686 libaio-devel.i686 libaio-devel.x86_64 libXext.x86_64 libXext.i686 libXtst.x86_64 libXtst.i686 libX11.x86_64 libX11.i686 libXau.x86_64 libXau.i686 libxcb.x86_64 libxcb.i686 libXi.x86_64 libXi.i686 make.x86_64 sysstat.x86_64
yum本地源配置参考：http://www.cnblogs.com/jyzhao/p/3938290.html
4.3 系统参数调整
/etc/sysctl.conf
# Oracle EM 13c
fs.aio-max-nr = 1048576
fs.file-max = 65536
kernel.shmall = 2097152

net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
sysctl -p 生效。

4.4 oracle环境变量：
环境变量中包含了两个产品目录：
- OMS
- Agent
oracle环境变量：
# Oracle OMS
export ORACLE_BASE=/u01/app/oracle
export OMS_HOME=$ORACLE_BASE/product/oem13.2/middleware
export AGENT_HOME=$ORACLE_BASE/product/oem13.2/agent/agent_13.2.0.0.0
4.5 创建目录：
chown oracle.oinstall /u01
su - oracle
mkdir -p /u01/app/oracle/product/oem13.2/agent
mkdir -p /u01/app/oracle/product/oem13.2/middleware
4.6 开始安装：
[oracle@OMS u01]$ ./em13200p1_linux64.bin

This information is also available at:
/u01/app/oracle/product/oem13.2/middleware/install/setupinfo.txt
See the following for information pertaining to your Enterprise Manager installation:
Use the following URL to access:
1. Enterprise Manager Cloud Control URL: https://OMS:7802/em
2. Admin Server URL: https://OMS:7102/console
3. BI Publisher URL: https://OMS:9803/xmlpserver
The following details need to be provided while installing an additional OMS:
1. Admin Server Host Name: OMS
2. Admin Server Port: 7102
You can find the details on ports used by this deployment at : /u01/app/oracle/product/oem13.2/middleware/install/portlist.ini
NOTE:
An encryption key has been generated to encrypt sensitive data in the Management Repository. If this key is lost, all encrypted data in the Repository becomes unusable.
A backup of the OMS configuration is available in /u01/app/oracle/product/oem13.2/gc_inst/em/EMGC_OMS1/sysman/backup on host OMS. See Cloud Control Administrators Guide for details on how to back up and recover an OMS.
NOTE: This backup is valid only for the initial OMS configuration. For example, it will not reflect plug-ins installed later, topology changes like the addition of a load balancer, or changes to other properties made using emctl or emcli. Backups should be created on a regular basis to ensure they capture the current OMS configuration. Use the following command to backup the OMS configuration:
/u01/app/oracle/product/oem13.2/middleware/bin/emctl exportconfig oms -dir <backup dir>
至此完成OMS的安装。

5.OMS：添加监控资源
OEMCC监控的主机需要部署对应的agent，官档描述如下： > Oracle Management Agent (Management Agent) is one of the core components of Enterprise Manager Cloud Control that enables you to convert an unmanaged host to a managed host in the Enterprise Manager system. The Management Agent works in conjunction with the plug-ins to monitor the targets running on that managed host.我直接在OEMCC上手动添加目标：
起初在被监控的主机上部署agent时，碰到报错，如下：
报错信息文字：
在主机 192.168.1.61 上执行命令 cd /opt/app/scratch/agentHome/ADATMP_2018-01-23_13-38-45-PM;/opt/app/scratch/agentHome/ADATMP_2018-01-23_13-38-45-PM/agentDeploy.sh -ignorePrereqs ORACLE_HOSTNAME=192.168.1.61 AGENT_BASE_DIR=/opt/app/scratch/agentHome OMS_HOST=OMS EM_UPLOAD_PORT=4903 AGENT_INSTANCE_HOME=/opt/app/scratch/agentHome/agent_inst b_doDiscovery=false START_AGENT=false b_forceInstCheck=true -force AGENT_PORT=3872 失败
错误消息: The Oracle Management Server (OMS) host and port specified via OMS_HOST and EM_UPLOAD_PORT is not available. Pass in a valid hostname and port number for the OMS to successfully deploy the agent.
退出代码 :1
开始认为是主机间可能有防火墙没关闭，或者是端口配置不对，进一步根据MOS的一些文档说明：
- EM 12C: Enterprise Manager 12c Cloud Control Agent Silent Installation Fails while Validating OMS Host and Port (文档 ID 1368010.1)
- EM 12c Agent Install fails with ERROR: The Oracle Management Server (OMS) host and port specified via OMS_HOST and EM_UPLOAD_PORT is not available (文档 ID 1524756.1)
首先确认OMS的端口配置正确：

查看日志发现是这一段之后报错：

Validating the OMS_HOST & EM_UPLOAD_PORT has failed
根据文档1368010.1的思路排查：
1). OMS status
[oracle@OMS ~]$ $OMS_HOME/bin/emctl status oms

BI Publisher is disabled, to enable BI Publisher on this host, use the 'emctl config oms -enable_bip' command
OMS is ok.
2). ping OMS
[oracle@jystdrac1 ADATMP_2018-01-23_13-38-45-PM]$ ping OMS
ping: unknown host OMS

在OEMCC上部署agent（推送方式）步骤截图如下：
最后就可以在OEMCC上直观看到该主机的相关监控数据：
至此，我们就熟悉了OEMCC 13.2 的整体安装、部署、配置agent等基本操作，后续就可以在这个环境下逐渐深入学习并感受OEMCC的强大功能了。
