Oracle12C EMCC部署安装
在oracle 11g之前，管理集群一般都是用GC,但是到了 12c，为了适应“云”架构，oracle推出了新的集群管理软件EMCC，相比之前的GC而言，功能强大。
EMCC的部署方式跟oracle 11g GC的部署方式很类似，服务端安装OMS服务，客户端安装agent代理服务，OMS收集客户端的统计信息都是通过代理来完成的。
EMCC的部署同样也需要一个资料库来存储信息，资料库可以使用11g库，也可以使用12c库。
资料库部署：
这里选择使用12c(12.1.0.2)版本作为EMCC资料库。
安装oracle12C
系统要求：
磁盘至少6.4G
内存至少2G
配置yum源
安装软件包：
yum -y install binutils compat-libcap1 compat-libstdc++ gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel libXext libXtst libX11 libXau libxcb libXi make sysstat 设置内核参数：
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586Enter the following command to change the current values of the kernel parameters:
/sbin/sysctl -p安装目录级权限：
# mkdir -p /u01/app/
# chown -R oracle:oinstall /u01/app/
# chmod -R 775 /u01/app/用户及用户组设置：
id oracle
uid=440(oracle) gid=200(oinstall) groups=201(dba),202(oper)环境变量设置：
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1; export ORACLE_HOME
ORACLE_SID=jhdb; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
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=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH开始安装：
xhost +
su - oracle
./runInstaller 创建实例：
./dbca
选择高级安装（Advanced Mode）
Golbal database name:imdb
SID:imdb
创建pdbs ，当然也可以手工创建，手工创建请参考我另外一个文章：
http://mp.blog.csdn.net/mdeditor/79400588
EMCC部署：
1、系统预设：
系统内核参数调整
在/etc/sysctl.conf中添如下内核参数：
kernel.shmmax = 4294967296删除EM配置：
$ORACLE_HOME/bin/emca -deconfig dbcontrol db -repos drop安装编译依赖软件包
yum -y install glibc-devel-2.17-55.el7.i686.rpm修改数据库配置参数，不然会报错误：
alter system set processes= 500 scope=spfile;
alter system set session_cached_cursors=500 scope=spfile;
alter system set shared_pool_size=650M scope=spfile;
alter system set job_queue_processes=22 scope=spfile;
alter database add logfile size 320M;
alter system set open_cursors=350 scope=spfile;
alter system set sga_target=2g scope=spfile;
ALTER SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE;
alter system set parallel_max_servers = 20 scope=both;
2、选择高级安装模式
3、选择安装路径
4、选择安装插件
5、web服务配置
6、EMCC资料库配置，如果选择CDB作为资料库，需要使用pdb来作为资料库。
pdb在创建完成默认是关闭状态，需要打开。
alter pluggable database emrep open;
EMCC添加目标：
在11g之前的库安装代理，一般都是通过在客户端登陆服务端发布的网址来下载安装包，然后在客户端安装代理。但是在12c的时候，安装代理要方便很多，直接在服务端推送代理到客户端，在推送之前需要设置客户端和服务端之间的互信，需要注意的是需要配置彼此的主机名。
1 .
2 .
client中增加server的/etc/hosts配置，server中增加client的/etc/hosts。
10.37.2.254 jhim
10.37.2.33 emcc
10.37.2.111 ams2 . 服务端推送代理的时候需要输入客户端登录名，为了安全起见，需要设置sudo，在客户端设置sudo权限：
[root@localhost ~]# ls /usr/local/bin/sudo
ls: cannot access /usr/local/bin/sudo: No such file or directory
[root@localhost ~]# whereis sudo
sudo: /usr/bin/sudo /etc/sudo.conf /usr/share/man/man8/sudo.8.gz
[root@localhost ~]# ln -s /usr/bin/sudo /usr/local/bin/sudo
[root@localhost ~]# cp -p /etc/sudoers /etc/sudoers.bak
修改Defaults:oracle !requiretty
新增oracle ALL=(ALL) ALL
修改Defaults visiblepw
[root@localhost ~]# vi /etc/sudoers
#
# Refuse to run if unable to disable echo on the tty. This setting should also be
# changed in order to be able to use sudo without a tty. See requiretty above.
#
Defaults visiblepw
#
# Disable "ssh hostname sudo ", because it will show the password in clear.
# You have to run "ssh -t hostname sudo ".
#
Defaults:oracle !requirettyll
oracle ALL=(ALL) ALL在服务端运行如下脚本，配置互信，为后面推送代理程序做准备：
[oracle@EMCC ~]$ /u01/app/oms/oms/oui/prov/resources/scripts/sshUserSetup.sh -setup -user oracle -hosts jhim输入两次‘yes’,ssh 互信直接空格下一步，最后需要输入客户端oracle密码。
3 . 填写客户端主机信息
4 . 部署代理
5 . 服务端监控推送日志：

问题2：
oms 资料库部署在linux 6.6上，想监控windows 主机，发现代理不兼容。
看到这里，需要升级代理程序，由于没有mos账号，所以不能联机升级，只能脱机升级，
脱机打补丁需要首先下载em资料库，先升级em然后通过em去连接升级oms补丁。
按照提示升级。
把下载的补丁包上传到OMS服务器，登录到OMS服务器执行 ：
oracle@EMCC bin]$ ./emcli login -username=sysman
Enter password
Login successful
[oracle@EMCC bin]$ ./emcli import_update_catalog -file=/home/p9348486_112000_Generic.zip -omslocal然后就可以下载代理补丁了：
