创建安装目录

mkdir –r /data/oracle/middleware

mkdir –r /data/oracle/middlewareagent

五．dbca建库

19C可以选择标准模板建库

部分系统参数需要修改

alter system set parallel_min_servers=0;alter system set session_cached_cursors=400 scope=spfile;alter system set log_buffer=8M scope=spfile;alter system set open_cursors=600 scope=spfile;alter system set processes=800 scope=spfile;alter system set shared_pool_size=1G scope=spfile;alter system set session_cached_cursors=400 scope=spfile;redo log 设置300Malter database add logfile group 4 ('/data/OEMDB/redo04.log') size 400M;alter database add logfile group 5 ('/data/OEMDB/redo05.log') size 400M;alter database add logfile group 6 ('/data/OEMDB/redo06.log') size 400M;alter database drop logfile group 1;alter database drop logfile group 2;alter database drop logfile group 3;restart dbshutdown immediatestartup

alter system set "_allow_insert_with_update_check"=true scope=both;

If this key is lost, all encrypted data in the Repository becomes unusable.A backup of the OMS configuration is available in /data/oracle/gc_inst/em/EMGC_OMS1/sysman/backup on host SZSPLORCOEM01. See Cloud Control Administrators Guide for details on how to back up and recover an OMS.NOTE: This backup is valid only for the initial OMS configuration. For example, it will not reflect plug-ins installed later, topology changes like the addition of a load balancer, or changes to other properties made using emctl or emcli. Backups should be created on a regular basis to ensure they capture the current OMS configuration. Use the following command to backup the OMS configuration:/data/oracle/middleware/bin/emctl exportconfig oms -dir <backup dir>

如果添加主机ssh不是默认22端口 需要修改如下文件

[oracle@szsplorcoem01 resources]$ pwd/data/oracle/middleware/oui/prov/resources[oracle@szsplorcoem01 resources]$vi /data/oracle/middleware/oui/prov/resources/Paths.properties

六．新加被监控集群

1. 手动配置安装代理
2. 确保OEM主机和db主机host都配置OK

1. 主机选择主机名，和平台 11g目前只支持linux x86-64

1. 配置安装目录 --确保安装目录不存在，系统会自动创建

1. 配置oracle用户名和密码

1. 配置root 用户和密码

1. 开始部署

1. 初始化部署 可能会需要一些时间

cd /u01/app/oracle/agent/ADATMP_2023-05-30_15-23-43-PM;/u01/app/oracle/agent/ADATMP_2023-05-30_15-23-43-PM/agentDeploy.sh -ignorePrereqs ORACLE_HOSTNAME=jxrac01 AGENT_BASE_DIR=/u01/app/oracle/agent OMS_HOST=SZSPLORCOEM01 EM_UPLOAD_PORT=4903 AGENT_INSTANCE_HOME=/u01/app/oracle/agent/agent_inst b_doDiscovery=false START_AGENT=false b_forceInstCheck=true -force AGENT_PORT=3872

报错处理：

如果遇到如下问题 请排查

1. db端和oms端的hosts文件均配置好主机IP应对关系
2. wget https://SZSPLORCOEM01:4903/empbs/upload --no-check-certificate

异常

正常 此命令能够正常执行是是否能推送成功agent的前提

报错图片

添加RAC集群

1. 首先按上面的步骤将agent在主机上安装好
2. 自动发现主机上的目标

点到新加主机，然后点立即搜索

1. 添加集群数据库

依次添加两个实例 测试连接，下一步完成

异常处理 dbname重复问题

如果dbname重复可能无法加入会报错

以下目标已经存在于基于属性的资料档案库中:- jxmes : rac_database

解决办法如下

1. 首先搜索主机上的目标，找到主机上的集群数据库的名字

如果已经集群的dbname重复了，则发现的集群数据库可能会是如下图

orcl_1 或者是大写的ORCL等等 只要名字不通就可以添加成功
