注意:OEM管理RAC數據庫須要先添加主機,集羣高可用服務(也能夠直接添加數據庫,不添加高可用服務,後續文檔補充),後添加數據庫;單機先添加主機(不用添加集羣高可用服務),後添加數據庫,GC服務器很耗資源,須要安裝oracle軟件,建立實例再配置OEM服務端,agent端,建議服務端32G+內存。
安裝Enterprise Manager Cloud Control 12c的硬件要求如如下列表,要求至少4G內存,
Linux 6.X 須要的依賴包以下:
yum -y install make binutils gcc libaio glibc-common libstdc++ sysstat glibc-devel glibc-devel
linux 5.X的依賴包以下:
yum -y install make binutils gcc libaio glibc-common libstdc setarch sysstat rng-utils libXtst xorg-x11-utils
注意: server和agent端都須要安裝依賴包
須要的軟件包:
em12105_linux64_disk1
em12105_linux64_disk2
em12105_linux64_disk3

若是數據庫配置了dbcontrol,使用以下命令將其刪除:
SYSMAN_PWD: Password for SYSMAN user
SYS_PWD: Password for SYS user
$ emca -deconfig dbcontrol db -repos drop -SYS_PWD -SYSMAN_PWD
刪除EM案例:
$ emca -deconfig dbcontrol db -repos drop -oracle -Oracle123
建立目錄
mkdir -p /u01/app/oracle/Middleware/
mkdir -p /u01/app/oracle/agent
chown -R oracle:oinstall /u01/app/oracle/Middleware
chown -R oracle:oinstall /u01/app/oracle/agent
解壓文件(同一個目錄解壓)
unzip em12105_linux64_disk1
unzip em12105_linux64_disk2
unzip em12105_linux64_disk3
注意:確保安裝目錄空間至少14G
修改一下參數:
可酌情修改參數,GC服務器很耗資源,建議參數不要過小。
oracle用戶進入解壓目錄,運行./runInstaller
選擇」Skip」跳過更新,點擊NEXT
Prerequisite checks安裝檢測,如遇報錯,請根據提示修改(或者忽略),點擊NEXT
定製版本:
安裝目錄選擇,middleware HOME目錄必定要爲空
Host name 能夠不爲域名格式
用戶名密碼設置:
weblogic/XXX
sysman/XXX
配置oem服務用戶名和密碼:
服務端口號設置:默認便可:
下一步:
執行腳本:
查看服務器端的OEM 狀態:
/u01/app/oracle/Middleware/oms/bin/emctl status oms
查看服務器端agent狀態:
/u01/app/oracle/agent/agent_inst/bin/emctl status agent
控制檯地址:
啓動OEM時,須要先啓動所在oms服務器的數據庫,以及中間件控制檯,最後啓動OMS(安裝完成後,默認已啓動),啓動中間件管理臺(默認服務器重啓會自動啓動):
Root:
nohup /u01/app/oracle/gc_inst/user_projects/domains/GCDomain/bin/startWebLogic.sh &
控制檯地址:
https:// IP:7102/console
啓動oms:
Oracle:
/u01/app/oracle/Middleware/oms/bin/emctl start oms -all
啓動客戶端:
/u01/app/oracle/agent/agent_inst/bin/emctl start agent

2.3.1.前期環境準備
mkdir -p /u01/agent/
chmod oracle.oinstall /u01/agent
注意:
1./u01/agent/ 必定要爲空。
2.全部監控服務器/etc/hosts 配置域名解析
3.全部服務器作如下sudo文件配置:
確保/usr/local/bin/sudo 這個符號連接存在
ROOT:
ln -s /usr/bin/sudo /usr/local/bin/sudo
ls -l /etc/sudoers
-r--r----- 1 root root 3407 Oct 18 19:30 /etc/sudoers

重啓sshd 服務:service sshd restart
2.3.2.安裝agent
設置 -> 添加目標 ->手動添加目標
靜默安裝agent參照:http://www.cnblogs.com/hmwh/p/8657498.html
添加須要監控的數據庫:

進行保存(已添加過能夠更新)
上圖能夠根據選擇添加主機的集羣高可用服務。
點擊 Target -> Database -> add 添加數據庫配置信息:(注意,若是有多套cluster 數據庫添加,也能夠用這種辦法添加:http://www.cnblogs.com/hmwh/p/8657498.html)

注意如下圖須要配置1,2,3:
依次配置1,2,3;配置2的時候,設置實例->監聽程序計算機名,須要設置IP,最好不要寫成域名。
