Oracle cloud control 12c整个安装比较复杂，光是安装路径的选择，登录密码，端口号等众多个配置不免让人眼花缭乱，目不暇接。本文描述的是安装完毕后如何获取安装时设定的各类端口号，URL以及如何启动、关闭cloud control等等，供大家参考。
有关cloud control的安装配置可以参考：Oracle Enterprise Manager Cloud Control 12c Release 3 Installation
1、当前的环境配置
[oracle@oel63 ~]$ more ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=oel63.ycdata.net; export ORACLE_HOSTNAME
ORACLE_UNQNAME=ora11g; export ORACLE_UNQNAME
ORACLE_BASE=/u01/ora11g; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/db_1; export ORACLE_HOME
ORACLE_SID=ora11g; export ORACLE_SID
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
export OMS_HOME=/u01/oms12cr3/oms
export AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0
[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
2、启动repository DB及OMS
#启动oms前，需要先启动Repository DB，该DB用于存放收集到的监控信息
#启动DB时，同时需要启动监听器，否则收到Failed to connect to repository database.
#不过OMS会自动重启，当侦测到DB和监听处于UP时(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
#使用以下的命令启动oms以及agent
[oracle@oel63 ~]$ $OMS_HOME/bin/emctl start oms
[oracle@oel63 ~]$ $AGENT_HOME/bin/emctl start agent
3、查看安装信息
#通过查看之前的安装信息以及端口信息，然后据此连接到cloud control console
[oracle@oel63 ~]$ cd $OMS_HOME/install
[oracle@oel63 install]$ more eminstall.info
INSTALL_TYPE=NOSEED
UPGRADE=false
ORACLE_MIDDLEWARE_HOME_LOCATION=/u01/oms12cr3 #Weblogic安装位置
OMS_HOME=/u01/oms12cr3/oms #OMS安装位置
AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0 #Agent安装位置
AGENT_BASE_DIR=/u01/agent12cr2 #Agent基目录

[oracle@oel63 install]$ more portlist.ini

Enterprise Manager Upload Http SSL Port=4903
Enterprise Manager Central Console Http SSL Port=7802
Node Manager Http SSL Port=7403

[oracle@oel63 install]$ more setupinfo.txt
This information is also available at:
/u01/oms12cr3/oms/install/setupinfo.txt
See below for information pertaining to your Enterprise Manager installation:
#以下是登录到cloud control console以及登录到Weblogic的URL,根据这个URL登录后进行相应的管理
Use the following URL to access:
1. Enterprise Manager Cloud Control URL: https://oel63.ycdata.net:7802/em
2. Admin Server URL: https://oel63.ycdata.net:7102/console
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 <backup dir>
4、关闭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;
