Oracle Enterprise Manager Cloud Control 13c 配置——Linux目标重定向（EMCC12c代理升级EMCC13c）
2024-05-25 03:48:40
背景描述：
1，当前有一套EMCC12c的监控，最近规划将EMCC12c的监控迁移到EMCC13c的监控，原有的EMCC12c监控的目标端需要重新定向到EMCC13c
2，参考资料：
（Redirecting Oracle Management Agent to Another Oracle Management Service）https://docs.oracle.com/cd/E24628_01/install.121/e24089/appdx_repoint_agent.htm#EMADV14498
13.3的版本
https://docs.oracle.com/en/enterprise-manager/cloud-control/enterprise-manager-cloud-control/13.3.1/emadv/redirecting-oracle-management-agent-another-oracle-management-service.html#GUID-5FBE50D6-2DE4-4420-A11A-D41B5E543A63
步骤：
将Oracle管理代理重定向到另一个Oracle管理服务（OMS）
1，确保新的OMS版本和管理的代理版本一致，或者更高的版本
2，确保新的OMS上部署了和老OMS相同的插件集(plug-ins)，或者版本更高的插件集
查看OMS插件集：（设置——可扩展性——插件）
查看agent代理插件集：$<AGENT_INSTANCE_HOME>/bin/emctl listplugins agent -type all
3，确保需要重定向的代理软件已启动并运行，然后运行以下命令重建 plugins.txt文件
$AGENT_HOME/perl/bin/perl $AGENT_HOME/sysman/install/create_plugin_list.pl -instancehome <AGENT_INSTANCE_HOME>
（默认情况下，在create_plugin_list.pl中将perl安装位置指定为/usr/local/bin。如果perl安装在管理代理主机的其他位置，请确保编辑create_plugin_list.pl的第一行，并指定安装perl的位置。）
4，停止管理代理
$<AGENT_INSTANCE_HOME>/bin/emctl stop agent
5，在旧的OMS上删除代理（可不做）
$<OMS_HOME>/bin/emcli delete_target -delete_monitored_targets -name=<name_of_agent_target> -type="oracle_emd"
6，移除代理实例目录
rm -rf <absolute_path_to_agent_instance_home>
7，运行带有 -configOnly 选项的agentDeploy.sh (agentDeploy.bat for Microsoft Windows hosts) 脚本，创建一个新的实例指向新的OMS
$<AGENT_BASE_DIR>/core/12.1.0.5.0/sysman/install/agentDeploy.sh AGENT_BASE_DIR=<absolute_path_to_agent_base_dir> AGENT_INSTANCE_HOME=<absolute_path_to_agent_base_dir>/agent_inst AGENT_PORT=<port_for_agent_process> OMS_HOST=<new_oms_host_name> EM_UPLOAD_PORT=<upload_port> AGENT_REGISTRATION_PASSWORD=<agent_reg_password> b_upgrade=false b_12cupgrade=false b_agentUpgrade=false b_noUpgrade=true -configOnly
linux目标的重定向
1，目标端配置环境变量
[oracle@zg ~]$ vi .bash_profile
目录根据实际情况配置
添加如下：
export AGENT_HOME=/agent/core/12.1.0.5.0
export AGENT_INSTANCE_HOME=/agent/agent_inst2，看目标端agent状态以及插件版本
[oracle@zg ~]$ $AGENT_INSTANCE_HOME/bin/emctl status agent
