??? Oracle cloud control 12c整個安裝比較復雜，光是安裝路徑的選擇，登錄password，端口號等眾多個配置不免讓人眼花繚亂，目不暇接。本文描寫敘述的是安裝完成后怎樣獲取安裝時設定的各類端口號，URL以及怎樣啟動、關閉cloud control等等，供大家參考。
??? 有關cloud control的安裝配置能夠參考： Oracle Enterprise Manager Cloud Control 12c Release 3 Installation

1、當前的環境配置
[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、啟動repository DB及OMS
#啟動oms前，須要先啟動Repository DB，該DB用于存放收集到的監控信息
#啟動DB時，同一時候須要啟動監聽器，否則收到Failed to connect to repository database.
#只是OMS會自己主動重新啟動，當偵測到DB和監聽處于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

?

#使用下面的命令啟動oms以及agent
[oracle@oel63 ~]$ $OMS_HOME/bin/emctl start oms
[oracle@oel63 ~]$ $AGENT_HOME/bin/emctl start agent

?

3、查看安裝信息
#通過查看之前的安裝信息以及端口信息，然后據此連接到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安裝位置
OMS_HOME=/u01/oms12cr3/oms???????????????????? #OMS安裝位置
AGENT_HOME=/u01/agent12cr2/core/12.1.0.3.0???? #Agent安裝位置
AGENT_BASE_DIR=/u01/agent12cr2???????????????? #Agent基文件夾

?

#下面是一些重要的端口信息 Author : Leshami?? Blog : http://blog.csdn.net/leshami
[oracle@oel63 install]$ more 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 setupinfo.txt

This information is also available at:

??????? /u01/oms12cr3/oms/install/setupinfo.txt

See below for information pertaining to your Enterprise Manager installation:

?

#下面是登錄到cloud control console以及登錄到Weblogic的URL,依據這個URL登錄后進行對應的管理
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、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;
