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sids_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.rspORACLE_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

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。
