Installing Enterprise Manager Cloud Control 12c release2 on Linux(安装em12c)

oracle推出了新一代的企业管理器Enterprise Manager Cloud Control 12c,目前在OTN已经可以下载到12c Release 2版本,下面记录一下安装过程,期间因为安装过程中关机重装带来了一些问题,总体安装很简单

EM 12c在安装时和11EM相似,只是增加了Plug-ins 的选择,Plug-ins 和 Connectors做为GRID CONTROLE的扩展并增加了一些非oracle的产品整合为”Cloud”云管理包含DATABASE,Middleware,VM server

目前包含的plug-ins包含 Oracle Database, Oracle Exadata, My Oracle Support, Oracle Fusion Middleware, Oracle Virtualisation  IBM DB2, Sybase ,ms-sqlserver, .net,apathe tomcat 等等

我是安装在OEL 5.8 X64平台上,Enterprise Manager Cloud Control 12c 也是r2版本在ORACLE官方网站都可下载到,em 12c总共目前5G(两个压缩包),包含了Weblogic server,只要一台内存在4G以上cpu2个以上的机器安装Small模式

其它硬件要求

Small Medium Large
(1 OMS, <=1000 targets, <100 agents) (2 OMSes for <=10,000 targets and <1000 agents) (> 2 OMSes, >=10,000 targets, >=1000 agents)
CPU Cores/Host 2 4 8
RAM 4 GB 6 GB 8 GB
RAM with ADPFoot 1 , JVMDFoot 2 6GB 10 GB 14 GB
Oracle WebLogic Server JVM Heap SizeFoot 3 512 MB 1 GB 2 GB
Hard Disk Space 7 GB 7 GB 7 GB
Hard Disk Space with ADP, JVMD 10 GB 12 GB 14 GB

Packages required:

  • binutils-2.17.50.0.6
  • gcc -4.1.1
  • libaio-0.3.106
  • glibc-common-2.3.4

•Enterprise Manager Upload HTTP SSL Port = 1159, 4899 – 4908

•Enterprise Manager Central Console HTTP SSL Port = 7799 – 7809

•Oracle Management Agent Port = 3872, 1830 – 1849

Repository Database requirements
所需要数据库存放数据要先安装,推荐的版本是11202,11203,10205,如果是11201还要修复 bugs 10014178 、 8799099,我这里安装选用了10205

参数配置

open_cursors needs to be 300 to 400
processes should be greater than 300
session_cached_cursors between 200 and 500
job_queue_interval needs to be at least 20
shared pool size minimum 600 MB
Redo log file sizes minimum 300 MB and 3 groups or more
UNDO tablespace has a minimum space of 200 MB
pga_aggregate_target size minimum 1g
sga_target greater than 2g

停止 Gather Statistics job

For 10g use :
execute dbms_scheduler.disable(‘GATHER_STATS_JOB’,TRUE);
execute dbms_scheduler.stop_job(‘GATHER_STATS_JOB’,TRUE);

For 11g use :
execute dbms_auto_task_admin.disable(‘auto optimizer stats collection’,null,null);

下面开始安装,我是把数据库和oem装在了一台机器上,从装操作系统开始
1,install OEL5.8 X64 OS

2,install oracle-validated 为了简化安装,并帮配置内核参数

放入OS安装DVD盘,配置yum源
[root@oem u02]# vi /etc/yum.repos.d/public-yum-el5.repo
[oel5]
name = Enterprise Linux 5.8 DVD
baseurl=file:///media/disk/Server/
gpgcheck=0
enabled=1
[root@oem u02] yum install oracle-validated

3,install oracle database 10201

./runInstaller -ignoreSysPrereqs

4,install oracle database 10205 patch
如果选择了配置OEM最后会有异常不影响数据库,bug read node 1222603.1,如果dbca前后都可以通过应用8350262补丁解决,因为安装em12c是不允许配置db console和grid control的,所以忽略

5,修改db 参数,参照上面的需要

SQL> alter system set processes=350 scope=spfile;
SQL> alter system set session_cached_cursors=300 scope=spfile;
SQL> alter system set shared_pool_size=700M;
SQL> alter system set pga_aggregate_target=1100m;
SQL> alter system set job_queue_processes=25;
sql> alter system set shared_pool_size=700m;

6,netca 配置listener并启动

7, drop repository db for db console and grid control

[oracle@oem ~]$ emca -deconfig dbcontrol db -repos drop

8,增加em12c 专用os用户(不是必需)
[root@oem ~]# useradd -g oinstall – cloud
[root@oem ~]# passwd cloud

[root@oem ~]#vi /etc/security/limits.conf
##—append for em—-
cloud soft nofile 4096
cloud hard nofile 4096

9, 创建em 安装目录配置正确的权限,解压安装文件包

[root@oem u02]# hostname
oem

[root@oem u02]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost
#::1 localhost6.localdomain6 localhost6
192.168.168.191 oem.anbob.com oem

10,用 Enterprise Manager Prerequisite Kit utility (emprereqkit)进行装前检查,注意修改为自己的数据库配置
su – cloud
unset ORACLE_HOME ORACLE_BASE ORACLE_SID
/u02/em12c是安装文件解压后目录
[cloud@oem bin]$ pwd
/u02/em12c/install/requisites/bin

[cloud@oem bin]$ ./emprereqkit -executionType install -prerequisiteXMLLoc /u02/em12c/install/requisites/list -dbHost oem -dbPort 1521 -dbSid oem12c -dbUser SYS -dbPassword syspassowrd -dbRole sysdba -showPrereqs

11,正式安装

[cloud@oem em12c]$./runInstaller

按照图形提示就可以,最后要用root执行一个allroot.sh
最后一页是成功的提示文件在/install/setupinfo.txt

    Enterprise Manager Cloud Control can communicate only with Oracle Management Agent 12c and not with any other earlier release of the Management Agent. You can not configure your exising Agents to communicate with Enterprise Manager 12c OMS
