一、GC系统架构
包括OracleManagement Service(OMS),OracleManagement Agent,OracleManagement Repository,GridControl Console四个组成部分. 系统架构如下:
二、安装准备工作
1）、对于OMS安装，需要卸载系统原有的dbcontrol，以下为卸载步骤：
[oracle@ocm1 soft]$ emctl status dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0
Copyright (c) 1996,2011 Oracle Corporation. All rights reserved.
https://ocm1:1158/em/console/aboutApplication
Oracle Enterprise Manager 11g is not running.

[oracle@ocm1 soft]$ emctl stop dbconsole

https://ocm1:1158/em/console/aboutApplication
Oracle Enterprise Manager 11g is not running.
卸载dbcontrol：
[oracle@ocm1 soft]$ emca -deconfig dbcontrol db -repos drop

2）、配置数据库参数
14:42:46 SYS@ enmoedu>ALTER SYSTEM SET log_buffer=10485760 SCOPE=SPFILE;
System altered.
14:43:00 SYS@ enmoedu>ALTER SYSTEM SET processes=500 SCOPE=SPFILE;
System altered.
14:43:14 SYS@ enmoedu>ALTER SYSTEM SET session_cached_cursors=200 SCOPE=SPFILE;
System altered.
14:44:39 SYS@ enmoedu>alter database datafile 3 resize 200m;
Database altered.
调整redo logfile的size，每个日志组大小为200m。
3）、配置Oracle用户环境变量
[oracle@ocm1 ~]$ cat .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=emrp
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export ORACLE_MIDDLEWARE_HOME_LOCATION=/u01/app/Oracle/Middleware
export OMS_HOME=/u01/app/Oracle/gc_inst
三、安装OMS
1）、首先安装JDK要求版本在1.6以上（可以从OTN下载）
[root@ocm1 soft]# rpm -ivh jdk-8u101-linux-x64.rpm
Preparing... ########################################### [100%]
1:jdk1.8.0_101 ########################################### [100%]
Unpacking JAR files...
tools.jar...
plugin.jar...
javaws.jar...
deploy.jar...
rt.jar...
jsse.jar...
charsets.jar...
localedata.jar...
2）安装Weblogic
由于OTN现在只提供10.3.6版本以上版本的下载，多次使用10.3.6（32或64位），在OMS configuration阶段总是“Failed”；根据多方面建议，选择10.3.2版本，由于系统、数据库、GC都是64位版本，建议Weblogic也使用64位版本。本次安装没有能获得10.3.2的64位版本，故用32位代替。
[oracle@ocm1 soft]$ export DISPLAY=192.168.8.254:0.0
[oracle@ocm1 soft]$ chmod +x wls1032_linux32
[oracle@ocm1 soft]$ ./wls1032_linux32
Launcher log file is /tmp/OraInstall2016-09-20_02-15-34PM/launcher2016-09-20_02-15-34PM.log.
Extracting files..........
Starting Oracle Universal Installer
Weblogic安装完后，不选择“quick start”；不需要配置Weblogic的domain，在安装GC时会配置。
3）安装Grid Control （Version：11.1.0.1 ，64位）
对于Grid Control的安装，注意配置主机名，需要有域名支持
[root@ocm1 soft]# cat /etc/hosts
127.0.0.1 localhost
192.168.8.200 ocm1.enmoedu.com ocm1
[root@ocm1 soft]# ls -l gc
total 4328832
-rwxr--r-- 1 oracle oinstall 1430649530 Sep 20 12:00 GridControl_11.1.0.1.0_Linux_x86-64_1of3.zip
-rwxr--r-- 1 oracle oinstall 1589671704 Sep 20 10:43 GridControl_11.1.0.1.0_Linux_x86-64_2of3.zip
-rwxr--r-- 1 oracle oinstall 1408054645 Sep 20 11:52 GridControl_11.1.0.1.0_Linux_x86-64_3of3.zip
[oracle@ocm1 soft]$ export DISPLAY=192.168.8.254:0.0
[oracle@ocm1 gc]$./runInstaller
注意：GC的安装要求主机物理内存在3G以上
注意：图中Middleware Home Location：应该为 ‘/u01/app/Oracle/Middleware'
注意：图中SID根据数据实际情况应该为：emrp
注意：图中路径中的“enmoedu”按照实际安装路径应该是“emrp”
注意：以“root”用户的身份运行脚本
注意：在weblogic使用10.3.6版本（32或64），在OMS configuration阶段总是“Failed”；在使用10.3.2后，安装成功！
Failed 日志：
weblogic 10.3.6 安装gc 错误：
OMS configuration：
[oracle@ocm1 ~]$ tail -f /u01/app/Oracle/Middleware/oms11g/cfgtoollogs/omsca/omsca_20160921043159.log

Congratulations： Grid Control Install 终于Success ！
三、安装后的验证
1）、查看OMS服务端口
[oracle@ocm1 gc]$ netstat -an |grep 7799
tcp 0 0 0.0.0.0:7799 0.0.0.0:* LISTEN
[oracle@ocm1 gc]$ netstat -an |grep 7101
tcp 0 0 192.168.8.200:7101 0.0.0.0:* LISTEN
tcp 0 0 192.168.8.200:7101 192.168.8.200:55547 ESTABLISHED
tcp 0 0 192.168.8.200:7101 192.168.8.200:55566 ESTABLISHED
tcp 0 0 192.168.8.200:55555 192.168.8.200:7101 ESTABLISHED
2）、查看OMS Server状态
[oracle@ocm1 gc]$ cd /u01/app/Oracle/Middleware/oms11g/bin
[oracle@ocm1 bin]$ ./emctl status oms
Oracle Enterprise Manager 11g Release 1 Grid Control
Copyright (c) 1996,2010 Oracle Corporation. All rights reserved.
WebTier is Up
Oracle Management Server is Up
3）、查看OMS agent状态
[oracle@ocm1 bin]$ pwd
/u01/app/Oracle/Middleware/agent11g/bin
[oracle@ocm1 bin]$ ./emctl status agent
Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0
Copyright (c) 1996,2010 Oracle Corporation. All rights reserved.

---------------------------------------------------------------

[oracle@ocm1 bin]$
4）、通过console访问OMS
对于OMS通过浏览器访问的https端口是7799，http访问是7202
[oracle@ocm1 bin]$ netstat -an |grep 7202
tcp 0 0 192.168.8.200:7202 0.0.0.0:* LISTEN
tcp 0 0 192.168.8.200:27800 192.168.8.200:7202 ESTABLISHED
tcp 0 0 192.168.8.200:7202 192.168.8.200:61800 TIME_WAIT
tcp 0 0 192.168.8.200:7202 192.168.8.200:27792 ESTABLISHED
通过http访问连接到OMS，访问成功！
总结：
对于Oracle 11g Grid Control安装过程并不复杂，但是必须保证Weblogic版本和Grid Control版本匹配，才能保证安装顺利进行！
后续：Oracle 11g Grid Control Agent install
