早期的Grid Control问题实在太多了，以至于把10.2.0.1的Grid Control升级到10.2.0.5几乎是不可能完成的任务；此外10.2.0.5以前的gc不支持11g作为repository database仓库数据库，不仅于此10.2.0.1版本是不支持rhel5或OEL5的，如果想安装的话rhel/oel 4是仅有理想的平台。这就这为我们制造了许多局限。如果是Fresh Installation的话似乎只安装软件(software only)，而不在安装10.2.0.1阶段配置oms，在升级到10.2.0.5后再进行oms的config会是一种比较理想的安装方法。不过我们仍需要应付一个复杂的配置过程，写这个文档的目的是帮助我们应付(包括已安装过的人，因为很容易忘记)这种窘况。
1.我们需要一个已经存在的Oracle数据库，当然它应当是纯净的(没有相关的em repository)，其版本最好是10.2.0.5或者11.2.0.2；我们假设你的数据库已经满足了一切安装grid control的前提要求，这包括设置几个初始化参数和装有dbms_shared_pool包等等。
2.其次你需要下载对应的软件，这包括了完全版本的10.2.0.1安装介质和10.2.0.5 gc patchset，并且最好有10.2.0.5版的agent(个人经验agent不太稳定，有时候需要重配，所以有介质的话会方便些):
- Linux_Grid_Control_full_102010_disk1.zip
- Linux_Grid_Control_full_102010_disk2.zip
- Linux_Grid_Control_full_102010_disk3.zip
- gc_x86_64_10205_part1of2.zip
- gc_x86_64_10205_part2of2.zip
- Linux_x86_64_Grid_Control_agent_download_10_2_0_5_0.zip
要下载这一大堆介质可能是我们安装过程中最麻烦的一件事情，特别是当你的网络状况欠佳的季节。
因为都是zip包，所以你只需要使用unzip命令将以上介质一一解压到合适目录就可以了。
3.配置OMS所在主机的内核参数和rpm包，下面给出了相关配置文件的示例值：
/etc/sysctl.conf:
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
# semaphores: semmsl, semmns, semopm, semmni
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
/* 注意以上参数并不一定适合你的主机，具体如何配置请参见Metalink文档 */
同时修改/etc/security/limits.conf参数文件:
* soft nproc 2047
* hard nproc 16384
* soft nofile 1024
* hard nofile 65536
/* 星号换上你的安装用户名，如oracle或者其他dba组成员 */
安装适当的rpm包，安装database时需要的包一律也都需要，此外请特别留意安装一下几个包:
compat-libstdc++-296-2.96-138.i386
libstdc++-devel-4.1.2-48.el5.x86_64
libstdc++-devel-4.1.2-48.el5.i386
glibc-devel-2.5-49.x86_64
glibc-devel-2.5-49.i386
并建立下列符号连接:
ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2
4.上述工作完成后我们需要修改response文件以满足安装的需要，在10.2.0.1安装介质的解压目录下操作:
[root@nas media]# ls
dcommon doc index.htm install libskgxn oms rdbms response runInstaller stage
[root@nas media]# vi response/em_using_existing_db.rsp
/* 修改em_using_existing_db.rsp响应文件 */
包括以下参数需要从默认值修改为指定值:
UNIX_GROUP_NAME="dba"
#dba应当是有效的安装用户所在组
FROM_LOCATION="/s01/media/oms/Disk1/stage/products.xml"
#FROM LOCATION指向安装介质stage目录下的products.xml文件
BASEDIR="/s01/app/gc"
#BASEDIR指向grid control安装的基础目录
INSTALLATION_NAME="oms10g"
#安装名
s_reposHost="rh3.oracle.com"
#repository数据库的主机名或ip地址
s_reposPort="1521"
#repository数据库的监听端口
s_reposSID="EMREP"
#repository数据库的sid
s_reposDBAPwd="maclean"
#repository数据库的sys用户密码
s_mgmtTbsName="/s01/orabase/oradata/EMREP/mgmt.dbf"
#repository数据库今后的mgmt表空间的数据文件名
s_ecmTbsName=s_mgmtTbsName="/s01/orabase/oradata/EMREP/mgmt_ecm.dbf"
#repository数据库今后的ecm表空间的数据文件名
s_securePassword="maclean"
#agent将来使用的secure密码
s_securePasswordConfirm="maclean"
#确认上一步的密码
b_lockedSelected=false
#确定agent交互是否被锁
s_reposPwd="maclean"
#确定仓库数据库中模式拥有者(sysman)的密码
s_reposPwdConfirm="maclean"
#确认上一步的密码
5.以静默方式安装grid control 10.2.0.1，但不配置oms:
[maclean@nas ~]$ export TMP=/tmp
[maclean@nas ~]$ /s01/media/install/runInstaller -noconfig -silent -ignoreSysPrereqs -responseFile \
/s01/media/response/em_using_existing_db.rsp use_prereq_checker=false b_skipDBValidation=true -force
以上安装完成后，运行相关脚本:
[maclean@nas ~]$ su - root -c "/home/maclean/oraInventory/orainstRoot.sh"
[maclean@nas ~]$ su - root -c "/s01/app/gc/oms10g/allroot.sh"
并使用opmonctl命令关闭http等服务:
[maclean@nas ~]$ /s01/app/gc/oms10g/opmn/bin/opmnctl stopall
opmnctl: stopping opmn and all managed processes...
5.接下来我们需要安装grid control 10.2.0.5补丁集，同样的需要修改一个response响应文件:
[maclean@nas 10205]$ unzip /tmp/gc_x86_64_10205_part2of2.zip
Archive: /tmp/gc_x86_64_10205_part2of2.zip
extracting: p3731593_10205_Linux-x86-64.zip
[maclean@nas 10205]$ unzip p3731593_10205_Linux-x86-64.zip
..............
[maclean@nas ~]$ cp /s01/10205/3731593/Disk1/response/patchset.rsp /s01/10205/3731593/Disk1/response/oms_patchset.rsp
/* 对oms_patchset.rsp修改已有的参数为指定值 */
[maclean@nas ~]$ vi /s01/10205/3731593/Disk1/response/oms_patchset.rsp
ORACLE_HOME="/s01/app/gc/oms10g"
b_softwareonly=true
s_sysPassword="maclean"
sl_pwdInfo={ "maclean" }
oracle.iappserver.st_midtier:szl_InstanceInformation={ "maclean" }
ORACLE_HOME_NAME="oms10g"
#另外增加以上条目
[maclean@nas ~]$ /s01/10205/3731593/Disk1/runInstaller -noconfig -silent \
-responseFile /s01/10205/3731593/Disk1/response/oms_patchset.rsp
/* 以上10.2.0.5补丁安装完成后，同样需要执行root.sh */
[maclean@nas ~]$ su - root -c "/s01/app/gc/oms10g/root.sh"
6.完成上述安装后可以开始配置OMS了:
[maclean@nas ~]$ export PERL5LIB=/s01/app/gc/oms10g/perl/lib/5.6.1
[maclean@nas ~]$ /s01/app/gc/oms10g/perl/bin/perl /s01/app/gc/oms10g/sysman/install/ConfigureGC.pl \
/s01/app/gc
Base Directory: /s01/app/gc
Starting ito execute Configuration Assistants:
Running the configuration assistants using the following command:
/s01/app/gc/oms10g/oui/bin/runConfig.sh INV_PTR_LOC=/s01/app/gc/oms10g/oraInst.loc
ORACLE_HOME=/s01/app/gc/oms10g ACTION=configure MODE=perform
COMPONENT_XML={encap_oms.1_0_0_0_0.xml}
perform - mode is starting for action: configure
以上命令的具体形式为:
<OMS ORACLE_HOME>/perl/bin/perl <OMS ORACLE_HOME>/sysman/install/ConfigureGC.pl <Parent Directory filepath>
配置会消耗大量的时间，建议通过.../oms10g/cfgtoollogs/oui/configActions<>.log.日志文件监控配置过程:
[root@nas oui]# cd /s01/app/gc/oms10g/cfgtoollogs/oui
[root@nas oui]# tail -f configActions2011-01-23_08-57-20-AM.log
... return status = 0 (success)

7.如果以上oms configuration顺利完成那么Grid Control的网页界面已经可以登录了，但我们在本地服务器上的agent仍是10.2.0.1版本的(所以Agent Configuration Assistant失败了)，这里我推荐将原agent目录删除后通过10.2.0.5的agent介质(Linux_x86_64_Grid_Control_agent_download_10_2_0_5_0.zip)重新安装并部署，这样可以很大程度上避免出现问题。
