[root@leo ~]# sysctl -p   --使參數生效

2.1 配置用戶shell限制

[root@leo ~]# vi /etc/security/limits.conf
oracle          soft    nproc           2047
oracle          hard    nproc           16384
oracle          soft    nofile          1024
oracle          hard    nofile          65536
oracle          soft    memlock         3145728
oracle          hard    memlock         3145728
oracle          soft    stack           10240
oracle          hard    stack           10240

2.2 模塊配置

[root@leo ~]# vi /etc/pam.d/login
session    required     /lib64/security/pam_limits.so

2.3 創建用戶和組

 groupadd oinstall
 groupadd dba
 useradd -m -g oinstall -G dba oracle
 echo "oracle"|passwd --stdin oracle
 mkdir -p /DBSoft/product/12.2.0.1/db_1
 chown -R oracle:oinstall /DBSoft

2.4 操作系統profile配置

[root@leo ~]# vi /etc/profile
if [ \$USER = "oracle" ]; then  
    if [ \$SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

2.5 配置oracle用戶環境變量

vi /home/oracle/.bash_profile
export EDITOR=vi
export ORACLE_SID=woo
export ORACLE_BASE=/DBSoft
export ORACLE_HOME=\$ORACLE_BASE/product/12.2.0.1/db_1
export LD_LIBRARY_PATH=\$ORACLE_HOME/lib
export PATH=\$ORACLE_HOME/bin:\$PATH
umask 022

2.6 關閉防火牆、selinux

chkconfig --level 345 ip6tables off
chkconfig --level 345 iptables off
service ip6tables stop
service iptables stop
sed -i "/^SELINUX=/s#enforcing#disabled#" /etc/selinux/config

2.7 修改hosts文件

vi /etc/hosts
192.168.3.2  leo

3 安裝數據庫軟件

[oracle@leo ~]$ ls
linuxx64_12201_database.zip
[oracle@oemdb ~]$ unzip linuxx64_12201_database.zip
[oracle@leo ~]$ ll

Successfully Setup Software.

3.1 GUI界面









這是一個bug，已經執行並且添加，不用管，詳見supprt (文檔 ID 2287806.1)，點擊忽略即可。



3.2 執行root腳本

[root@leo ~]# /DBSoft/oracle/product/12.2.0.1/db_1/root.sh 

4 DBCA創建數據庫
















修改日誌組的大小爲250M



4.1 修改數據庫配置

SQL> alter system set processes= 2000 scope=spfile;
SQL> alter system set session_cached_cursors=300 scope=spfile
SQL> alter system set open_cursors=350 scope=spfile;
SQL> alter system set sessions=2000 scope=spfile;
SQL> alter system set shared_pool_size=5120M scope=spfile;
SQL> alter system set "_allow_insert_with_update_check"=true;

5 安裝OEM
注意：OEM 13cR2安裝包下載之後不要解壓，直接執行em13200_linux64.bin文件會自動解壓到／tmp目錄中，隨後會會調用安裝程序起圖形界面，這個過程大約5-10分鐘，需耐心等待。













注意：看到這些信息要在數據庫端修改對應的參數再重新執行即可。







注意：經過3.5個小時的安裝終於出現彈出需要執行allroot.sh腳本界面，安裝基本告成。執行allroot.sh腳本

6 使用OEM
打開瀏覽器進入OEM頁面https://192.168.3.2:7802/em 用戶名sysman密碼oracle123
進入之後接受許可協議





7 安裝部署Agent
7.1 添加地址解析

在所有受管理的服務器增加OMS服務解析地址：
# echo “192.168.3.3     oem13c” >> /etc/hosts

7.2 部署Agent

7.3 執行root.sh腳本

所有受管節點以root用戶執行root.sh腳本
[root@leo ~]# /DBSoft2/oracle/product/oem13c/AgentHome/agent_13.2.0.0.0/root.sh

至此，EM13C Agent 部署完成。
