   Oracle cloud control 12c整個安裝比較複雜，光是安裝路徑的選擇，登入密碼，埠號等眾多個配置不免讓人眼花繚亂，目不暇接。本文描述的是安裝完畢後如何獲取安裝時設定的各類埠號，URL以及如何啟動、關閉cloud control等等，供大家參考。

有關cloud control的安裝配置可以參考：Oracle Enterprise Manager Cloud Control 12c Release 3 Installation
1、當前的環境配置
[oracle@oel63 ~]$ more /etc/issue
Oracle Linux Server release 6.3
Kernel \r on an \m

[oracle@oel63 ~]$ sqlplus -v
SQL*Plus: Release 11.2.0.3.0 Production

[oracle@oel63 ~]$ more ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
export PATH=$PATH:$HOME/bin

# Oracle Settings
export TMP=/tmp;
export TMPDIR=$TMP;
export ORACLE_HOSTNAME=oel63.ycdata.net;
export ORACLE_UNQNAME=ora11g;
export ORACLE_BASE=/u01/ora11g;
export ORACLE_HOME=$ORACLE_BASE/db_1;
export ORACLE_SID=ora11g;
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH;
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;
export OMS_HOME=/u01/oms12cr3/oms
export AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0

2、啟動repository DB及OMS
#啟動oms前，需要先啟動Repository DB，該DB用於存放收集到的監控資訊
#啟動DB時，同時需要啟動監聽器，否則收到Failed to connect to repository database.
#不過OMS會自動重啟，當偵測到DB和監聽處於UP時(OMS will be automatically restarted once it identifies that database and listener are up.)
[oracle@oel63 ~]$ lsnrctl start
[oracle@oel63 ~]$ ps -ef | grep pmon | grep -v grep
[oracle@oel63 ~]$ sqlplus / as sysdba
SQL> startup
SQL> exit

#使用以下的命令啟動oms以及agent
[oracle@oel63 ~]$ $OMS_HOME/bin/emctl start oms
[oracle@oel63 ~]$ $AGENT_HOME/bin/emctl start agent

3、檢視安裝資訊
#透過檢視之前的安裝資訊以及埠資訊，然後據此連線到cloud control console
[oracle@oel63 ~]$ cd $OMS_HOME/install
[oracle@oel63 ~]$ more $OMS_HOME/install/eminstall.info
INSTALL_TYPE=NOSEED
UPGRADE=false
ORACLE_MIDDLEWARE_HOME_LOCATION=/u01/oms12cr3 #Weblogic安裝位置
OMS_HOME=/u01/oms12cr3/oms                     #OMS安裝位置
AGENT_BASE_DIR=/u01/agent12cr2                 #Agent基目錄
AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0     #Agent安裝位置

#下面是一些重要的埠資訊
[oracle@oel63 install]$ more $OMS_HOME/install/portlist.ini
Enterprise Manager Upload Http Port=4889
Enterprise Manager Upload Http SSL Port=4903
Enterprise Manager Central Console Http SSL Port=7802
Node Manager Http SSL Port=7403
Managed Server Http Port=7202
Enterprise Manager Central Console Http Port=7788
Oracle Management Agent Port=3872
Admin Server Http SSL Port=7102
Managed Server Http SSL Port=7301

[oracle@oel63 install]$ more $OMS_HOME/install/setupinfo.txt
This information is also available at:
        /u01/oms12cr3/oms/install/setupinfo.txt
See below for information pertaining to your Enterprise Manager installation:

#以下是登入到cloud control console以及登入到Weblogic的URL,根據這個URL登入後進行相應的管理
Use the following URL to access:
        1. Enterprise Manager Cloud Control URL:
        2. Admin Server URL:

The following details need to be provided during the additional OMS install:
        1. Admin Server Hostname: oel63.ycdata.net
        2. Admin Server Port: 7102

You can find the ports details used by this deployment at : /u01/oms12cr3/oms/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/gc_inst/em/EMGC_OMS1/sysman/backup on host oel63.ycdata.net. 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/oms12cr3/oms/bin/emctl exportconfig oms -dir

4、關閉OMS及repository DB
[oracle@oel63 ~]$ $OMS_HOME/bin/emctl stop oms -all
[oracle@oel63 ~]$ $AGENT_HOME/bin/emctl stop agent
[oracle@oel63 ~]$ lsnrctl stop
[oracle@oel63 ~]$ export ORACLE_SID=ora11g
[oracle@oel63 ~]$ sqlplus / as sysdba
SQL> shutdown immediate;
